Crowley Eusford

Crowley Eusford (クローリー・ユースフォード) is a Thirteenth Progenitor among vampires and a member of Seventh Progenitor Ferid Bathory's faction. However, he hides his strength under Ferid's orders and is actually equal in strength to a Seventh Progenitor. He is also a Michaela.

Human
Crowley had blue eyes, short red hair, thick eyebrows, and his looks made him quite popular with the women.

Vampire
Crowley is a tall and muscular vampire with broad shoulders. He has red bangs and thick eyebrows, while the rest of his hair is dark brown. His back hair is long and kept in a braid that comes over his shoulder on the left side of his neck. He has a single piercing in each ear. Like all vampires, he has red eyes, fangs, and pointed ears.

As a progenitor, he does not wear the standard uniform for vampire soldiers. He wears black boots with white heels and toes that reach below his knees. He wears white pants and a white army shirt; the top buttons are undone to show his pecs. He has a black belt with a chain on the right side and his scabbard on the left. He wears a black sleeve and glove over his right arm, and this sleeve is fastened to his the cape that covers his left shoulder and reaches the back of his right shoulder. The sleeve has two white stripes at the end. He has a second cape trailing from his waist to the back of his knees. His overall attire represents that of what a crusader in the 13th century would wear.


 * Anime: In the anime, his shoulders are more narrow and less muscular.

Human
Crowley is calm and brave. He cares deeply about his comrades and trains hard to protect them during the Crusades. He is laid-back and gets along well with everyone. After their commander perishes, he leads the group due to his commander's final order. He tends to smirk a lot.

Despite his strength, he knows when he is beaten and gives up after a vampire slaughters his comrades and has him by the neck, much to that vampire's displeasure.

After surviving the Crusades, he suffers from PTSD and refuses to rise in the ranks of the knights which can indicate that he lacks ambition. Even so, he cares deeply about his friends and former comrades and fights to solve the mystery of their deaths and avenge them.

He loses his human life trying to warn his former comrades to escape and fights against Ferid until he can no longer move.

Vampire
Crowley is still calm and brave which makes him a patient vampire who enjoys fighting any opponent. Even when Crowley is in a tight spot, he remains calm with a pleasant smile. While Ferid tells him he does not care if he lives or dies, Crowley only looks mildly disappointed.

Despite sticking to Ferid, he appears to be emotionally detached to him, such as throwing the latter out of the bus as "revenge". Crowley also appears to be quite unimpressed with Ferid half of the time, calling his antics "stupid" and even sympathizing for the children getting dragged into the mess that Ferid created. He also doesn't appear to trust Ferid, and is not afraid to be blunt to him for it.

Whether things are interesting seems to be an important motive for Crowley's actions and movements. He joined Ferid Bathory's faction for this reason and while on the battlefield constantly, he exclaims when/if something impresses him with an almost childlike curiosity.

He has also displayed insight, noticing how fast humans are evolving and even deducing they can't have done it by themselves, which would mean a vampire has gone traitor. He discussed this with his aides, Seventeenth Progenitor Horn Skuld and Seventeenth Progenitor Chess Belle, whom he also warned about the weapons after testing the ability of one. Regarding Horn and Chess, Crowley is almost always in the company of his aides.

Crowley has a clear mind set concerning humans and views them nothing but livestock. He is willing to drain them completely without hesitation and use them as bait to attract more enemy soldiers.

He does not appear to be very susceptible to fear. Whether it is because he has yet to face a real threat in battle in the series or not is unknown. Crowley also does not seem to mind recognizing his enemies' abilities while in the battlefield; this is shown when he recognized the force of Goshi's illusion, saying that it was impressive that a illusion spell conjured by a human could affect even a vampire noble's brain.

Despite all of his views on humans and his displays of cruelty, Crowley does appear to retain some level of his humanity and can still treat humans with kindness and even sympathy. This is shown in recent chapters where he is shown to treat Yu and his squad kindly and patiently, even coaching them in fighting and showing pity at them for being involved in Ferid's schemes. Along with that, he almost looked horrified when learning that Ferid intends to have Yu see all of his family member corpses, showing despite having regularly taunted others sarcastically, he isn't actually so cruel. He also seems to look down on his former pride as a crusader and his views of humans also apparently extends to resenting them for their evil, clearly being uncomfortable when he talks on his human life and displaying disgust when he refers to humans as having killed more than Vampires. Despite having fed on humans remorselessly, he has stated that he has never killed even a single human as a vampire, implying that while he drained them of a great deal of their blood, he has not directly killed a human and all humans who may have died because of him were due to their weakness. Though this seems to be a view not always enforced about his admission of never killing a single human as a vampire, as he is shown at some point killing ten humans from the Moon Demon Company when they assault Chess and Horn at the attack on Nagoya.

History
Crowley used to be a crusader in the 13th century and was considered a hero. He believes in God until the reality of war and unanswered prayers changed him. When his commander dies, he stops praying to God. Even then, he still hopes for God to do something and even touches his commander's rosary until becoming a vampire.

Crowley first encounters a tan dark-haired vampire during the Crusades. Although Ferid is also there, Ferid does not talk to Crowley until years later. Ferid began watching for Crowley approximately 150 years before he turned Crowley because he was waiting for someone with the Michaela trait.

Ferid drives Crowley to hate him, using methods such as killing everyone who was important to him, and thus remember his face before force feeding him a vial of Saitō's blood to turn Crowley into a vampire. When Crowley finally hunts Ferid down decades later, Crowley's human feelings have waned to the point where he does not recall why he wanted revenge on Ferid, and he becomes Ferid's comrade. Crowley later says he joined Ferid Bathory's faction because Ferid always makes things interesting.

Events of 2016
In 2016, Crowley Eusford is in Sanguinem, and visits Ferid at a library. He asks Ferid about a kid named Sakuma in which Ferid responds that he is a Buddhist. Crowley asks what that is, which Ferid questions him if he actually know what Buddhism is. Crowley repeated the conversation he overheard between Ferid and Sakuma.

Hearing Ferid's mention of Christianity, Crowley remarks that he has forgotten Christianity, as God no longer watches over him. He expands on that asking if God was watching over him, why did he become a vampire? Ferid answers that Crowley's actions were to blame which shocks Crowley. Crowley then asks what Ferid is reading, which Ferid says is the Bible. Checking the cover, Crowley sees that the book is "History of Names", and asks if the book is interesting. Getting no response, he then asks why Ferid called him down to Sanguinem.

He reflects on the nightmare he has of his comrades being killed and flashbacks from battles during the Crusades. He wakes up to the sounds of swords clashing.

Shinjuku Arc
Crowley first appeared encountering Shinoa Hīragi's squad while they were on their way to Shinjuku, and intentionally rammed their hummer into him. He easily stopped it with one hand. Yoichi fired arrows at him, but he activated his sword, easily blocking the attack. He then slashes at Yoichi, but Shinoa and Mitsuba manage to deflect the attack. Shinoa warns her squad that he is armed with a first-class weapon, but he quickly steps behind her before she can finish talking. Kimizuki defends Shinoa while Yu cuts off his sword arm. In response, Crowley smiles, complements them, and asks who they are. His unreasonably chill response unnerves Yu.

His two female aides, Horn Skuld and Chess Belle, arrive and inform him that Seventh Progenitor Ferid Bathory requested his presence on the front lines. Disappointed, he smiles at Yu, moves behind him at supersonic speed, pats him on the shoulder, and promises to see him again before taking off. Like Ferid, he deems the teenagers lambs.

He finally makes it to the 5th Street intersection, and the squad he fights with him before heading there makes it before him, despite the fact he left first. This may be because he had to go all the way around the human fortress at Shinjuku while they simply went straight through it. Crowley arrives as Ferid draws his sword. Noticing him, Ferid returns his sword to his scabbard and gives the orders to turn the vampire extermination unit into vampire livestock. Mikaela Hyakuya attempts to kidnap Yūichiro while the other vampires attack the remaining humans. Crowley pins down Shinoa, and she screams. He straddles her with his hand around her neck.

When she tells Yu to run, he moves that hand to her mouth, informing her that cattle do not talk.

He bites her on the left side of her neck, and Yu undergoes a transformation into a one-winged monster. He strikes at Crowley, or rather the human beneath Crowley. Crowley avoids his attack, and he misses Shinoa by a few feet.

Returning to Ferid, Crowley asks for orders. Ferid questions Guren, who he has by the neck. The monster attempts to kill Shinoa, and Mika blocks the attack with his body, resulting in a serious injury. Shinoa hugs him, returning Yu to normal. Major General Shinya Hīragi snipes at Ferid, causing a small injury to Ferid's shoulder. The Shibuya Main Army arrives to reinforce the humans.

Crowley asks Ferid for orders. Ferid says he is going to leave and tells Crowley he can live or die, whichever he pleases. Ferid suggests they both just go home and claims he did what he wished to do. Crowley asks what Ferid wished to do, but Ferid claims that is his secret. Crowley retreats with the other vampires while Ferid grabs ahold of Mika.

Nagoya Arc
In the start of Nagoya, the Moon Demon Company of the Japanese Imperial Demon Army attacks Nagoya.

Crowley, Chess, and Horn wait in the Nagoya City Hall. The humans planned to kill Chess and Horn, but Crowley helps take down six squads of the Moon Demon Company, killing ten of them and keeping the remaining twenty as hostages. He releases a fatally-injured soldier named Kusunoki to deliver the news to Lieutenant Colonel Guren Ichinose. After this, although Guren initially planned on avoiding Crowley, he adds Crowley's name to his hit list. Crowley looks forward to their arrival. He waits with Chess and Horn, pondering over the demon weapons and wondering which high-ranking vampire has been traitorously aiding the humans. He cuts his finger while examining a demon blade and lets Horn lick his wound.

Yoichi fires Gekkōin at Crowley but he catches the manifested Gekkōin with his hands. Utterly unharmed, he then flings it aside. Yoichi recognizes Crowley as the vampire noble his squad encountered on their way from Harajuku to Shinjuku during the previous vampire attack. Guren and his team discuss what to do while Crowley, Horn, and Chess wait for them.

Horn speculates that the humans may be preparing an attack strong enough to wipe out all of them. Crowley agrees but adds that the humans may have an entirely different objective. Crowley decides to capture one of the humans as a souvenir for Ferid. Both Chess and Horn mention they do not like Lord Ferid because he is devious and hard to predict, even for them. Crowley counters that there is never a dull moment with Ferid. He then orders them to ignore the grunts and grab one or two of their more knowledgeable officers.

Shinya and Guren attack Crowley, but he easily negates their attacks at close-range. Crowley swings Guren into Shinya, throwing the pair straight through the wall behind him. Crowley, Chess, and Horn step toward them.

Crowley easily parries each of Guren and Shinya's attacks while only using one hand to hold his sword. Shinya and Guren struggle but manage to escape through a hole in the wall after they knock up enough dust.

Crowley's hand reaches through the wall and grabs Shinya by the chest, but Guren swings at the hand and drives it back. Guren puts Shinya's arm over his shoulder as they run down the hall. Crowley breaks through the wall and states that he hates running. He attacks them and cuts through Guren's left shoulder before remembering that he does not want to kill these two. Guren orders Shinya to abandon him and continue the mission. Crowley allows it.

Before Shinya can flee, the ground beneath Guren and Crowley breaks apart with Yu jumping through the floor.

Yu attacks Crowley, but he easily blocks it and moves to decapitate Yu. Kimizuki parries the attack, and Mitsuba distracts Crowley by summoning dummies with Tenjiryū. Yu uses Asura Kannon, but Chess and Horn immediately step in and defend Crowley from it. Chess and Horn counterattack and rip apart the shield Mitsuba forms with Tenjiryū.

Guren orders Shinoa Squad to leave. Crowley recognizes Yu as the one who went berserk in Shinjuku and comments that this battle has taken an unexpected turn.

Chess complains that the group blabbers too much and Horn asks Crowley if they can dispose of them. Crowley says no and states that this may be something for Ferid to deal with.

Guren orders Goshi to take action. Guren's squad breaks in through the windows, and he orders them to save Shinya and escape. Goshi makes an illusion of flames and magma, which startles Chess. Horn comments that the illusion is powerful enough to affect nobles, and Crowley once again wonders who the humans acquired such power from.

Crowley swings his sword and rips out the wall, commenting that Guren has been abandoned. Crowley orders Chess and Horn to restrain Guren and take him with them.

Yu battles with Crowley with the intent of rescuing Guren. Crowley defends himself on time, parrying the attack and wondering to himself whether Yu is really human.

Crowley activates his sword when Yu intends to attack him with Asura Kannon and attacks, impressed that Yu can dodge the attack as he goes for another attack. Seeing that Yū is able to block, Crowley commends he's a tough one and that he might just have to use both hands while wielding his sword.

Guren jumps between, yelling at Yu that Crowley is on a whole other level and Yu can't possibly hope to defeat him. Yu, shocked, asks himself why he still isn't strong enough.

Crowley comments on the words, telling Yu that it's simple because he's just livestock and that the vampires will never see them as a threat. Infuriated by the words and to Crowley's amusement, Yu attacks him once again. Crowley comments Yu is getting faster and Guren pleads for the boy to stop before the demon takes over.

The warning is thrown aside and Yu becomes (part) demon.

Delighted, Crowley states he knew that getting involved with Ferid would turn out interesting, his curiosity and interest growing, even stating he might just drink him dry next time he gets the chance.

At this point Kimizuki steps in and uses Kiseki-o to grab Yu and get out of there, encouraged by Guren. Crowley shows interest in the technique and makes no sign of pursuing.

Crowley is next seen revealing that five nobles were killed, and all of their whereabouts were known.

Ferid approaches Crowley. Crowley says there is "too much fun" going on, so Ferid must be behind it somehow. He accuses Ferid of leaking information to the humans, but Ferid says he hates fools who betray their comrades more than anything else. Crowley does not buy it and then says the thing that gets him is that Ferid sold out his location to the humans as well. He asks Ferid to explain that. He says he thought he was part of Ferid's faction.

Ferid points out that Crowley was entertained, and Crowley admits that. Ferid asks for thanks for sending something to liven up Crowley's boring day. Ferid says having a member of his own faction attacked makes him less likely to be suspected. Ferid admits to giving the information to humans, but he says someone even more twisted than he pulled the strings this time and points to Guren Ichinose, who lies beaten on the ground.

Crowley says Guren does not look like it, but Ferid says that Guren is a namanari. A namanari is a human one step short of becoming a full demon. He says there are two beings in Guren's body, and they share their time in control. He says one half is the idealist who wants to save his friends and followers. He says the other half is possessed by the vengeful spirit of Guren's dead lover, a perfectionist who reduced herself to a demon in order to get what she wants.

When Krul orders the vampires to set out for Nagoya Airport, a bit further away, Crowley asks Ferid about what is really about to start. Ferid laughs, stating that it is a grand party. He tells Crowley to stay close behind him at all times or else Crowley will die.

Later at the battle at Nagoya Airport after Yu returns from losing control of his Seraph, Crowley sneaks up behind Krul to attack the Queen as a distraction. His arm is sliced off by Krul as she then comments that his movements are too slow out of arrogance - in which Ferid then appears from behind her, stating that her pretty neck was open before ultimately biting into her shoulder.

Following the event, Crowley inquires Ferid about his plans, telling the Seventh that he too was interested in what he was planning. Learning that Ferid was only "wasting time", he proceeds to question Ferid whether his motives were acceptable, saying it would be punishable for him touching the Queen. His faction leader assures him that the higher powers (Progenitors) would soon come to punish Krul for her wrongdoings and betrayal and that due to the experimentations carried out by humans that vampires were no longer safe. Crowley watches by Ferid's side as the latter takes control over the vampires and commands them to eradicate the humans' research facilities.

Post-Nagoya Arc
Three months after the battle, Crowley is present when Ferid calls for an urgent call for the Progenitor Council. He speaks up, along with Horn and Chess, making small, irrelevant comments in between. They are scolded for their foolish behavior by 2nd Progenitor Urd Geales, when they do so. Later as Ferid reveals Krul's betrayal to the progenitor councils, Crowley comments that they were in trouble.

Shortly afterwards, the humans attacks Sanguinem and invades the palace.

Later on, Ferid drives a western car with Crowley in the passenger's seat. Crowley asks where they are headed, and Ferid says they are going to see his friends. After some banter, Ferid says they are actually going to a little fishing village to meet Yu and Mika and to "become their new best friends."

Crowley and Ferid quickly drive to the fishing village where the Shinoa squad and others had been hiding. Crowley points out that Ferid already killed Yu and Mika's entire family for fun, and Ferid agrees. Ferid says they are going on this trip to become their new best friends anyway. When Crowley says that is unlikely, Ferid cheerfully tells him to not be confined by common sense and says how the idea of "former enemies coming together all through the power of friendship" is so exciting. Ferid mentions killing all of Crowley's friends once and states that they are now "buddy-buddy."

Crowley points out the group spotted them and are running. Ferid orders Crowley to run after them since he is busy driving. When Crowley, who mentioned how much he hates running during the previous arc, then offers to drive instead, Ferid tells him to get going. He says Crowley needs to stop them. He can cut off a leg or two, but he tells Crowley not to kill them. Crowley brings up Ferid's previous comments about becoming buddy-buddy with Yu and Mika before jumping out of the car to chase after them. Crowley lands in front of their group and quickly races between them to strike Mitsuba's shoulder with his sword and send her flying. He throws her to the ground. He is pleased and says fighting will make waiting for Ferid less boring.

Mitsuba latches onto Crowley’s leg and orders the squad to abandon her and flee since they cannot waste time there. Yoichi refuses and shoots at Crowley, who easily deflects his shots.

Kimizuki manifests Kiseki-Ō and begins his count of nine, but Crowley recalls seeing that technique before. He considers pulling back and asks if Mitsuba would release his leg. When she refuses, he says he will just cut off her arms.

Shinoa steps in and blocks Crowley’s sword with her scythe. Yu tells Crowley he is surrendering, but Crowley says he is actually not after anything in particular himself.

Ferid appears behind Yu and Mika and nearly drives over them. He jeers that he heard they were being attacked by a dangerous vampire, so he came to their rescue. He says he will save them if they take a ride with him, but Crowley says they already finished that part and surrendered. After Ferid presents Akane's head in a jar to them, Crowley tells the humans he pities them for having to put up with Ferid's exhausting antics. As Yu struggles against his demon after seeing Akane's head, Kimizuki looks at Crowley and asks for a temporary truce. Crowley says he does not mind, and Ferid agrees. Sometime later, Crowley works on fixing a bus engine and comments he has learned a lot about fixing cars because Ferid keeps making him repair them. Not exactly pleased with the situation, the main characters enter the bus. Crowley drives them.

The group takes a brief rest stop. Ferid and Crowley joke about the kids' taking a long bathroom break. Crowley asks where they are really going, and Ferid confesses to lying about taking them to the place of the Seraph of the End experiment. He reveals he is actually taking them to Osaka Bay to rendezvous with Guren.

Osaka Arc
Back on the bus, Crowley says they have nearly reached Osaka Bay and asks for more information. Ferid only says they will become extremely busy and refuses to divulge anymore information in order to spare Crowley from being tortured. Ferid calls him his "precious son," and Crowley promptly rejects the notion. Crowley asks about Saitō, their sire, but Ferid says nothing.

Crowley asks if this is all to get back at Saitō and says he might get revenge on Ferid instead if Ferid says nothing, and Ferid only tells him to make it spectacular if he must. As Ferid appears to answer Mika's question of where they're going, Crowley slams on the breaks, which sends Ferid flying through the windshield and has Yu hit his head. After recovering from the crash, Ferid asks why Crowley stomped on the breaks, which the latter responds by asking if that was "spectacular" enough for Ferid, and Ferid shows surprise before laughing. He says he did not see that one coming.

Crowley tells Yu to not move or else he will get killed multiple times. He does not react when Ferid asks him if he tried his hardest under an incompetent queen. He then sees Ferid meet Saitō and asks if it is their father. He thinks trying to kill Saitō would be too hard, but Ferid tells him by practicing on Fifth progenitors and making their way up to Urd will make them strong enough to kill Saitō. Crowley does not reply to Ferid's words.

Crowley returns to where the humans are and watches Ferid get exposure torture. He tells Yu that they cannot rescue Ferid and Krul immediately and must wait. Crowley is amused by Ferid's screams and asks if Yu really wants to save them. He tells Yuu that exposure torture must be painful because both of them are screaming.

Yuu decides he wants to rescue them and asks if there is a way to do so. Crowley says there is but in order to do so they must tame the seraph of the end in Yuu and to do that they have to go to Ferid's mansion.

Crowley leads Shinoa Squad to Ferid's fifth mansion, and goes ahead of them to unlock the front door. Later Tenth Progenitor Fuola Honte fights Shinoa Squad and claims a monster is chasing him. Crowley then appears and steps out of the mansion, approaching Fuola. Fuola recognizes Crowley and says a thirteenth progenitor like him should be unable to touch a tenth. Crowley attacks him, beheading him and cleaving his torso in half before Fuola can even defend himself.

The group comments on Crowley’s strength, and Shinoa says she will not complain about their allies being too powerful. Fuola says Ferid will not forgive Crowley’s treachery, but Crowley says Ferid is the one who ordered him to do this. He turns Fuola into ash.

Crowley smiles and looks back at the teenagers. He says the battle formation takes him back to when he was human. He challenges them to see if they can defeat him.

They fight, and the teens lose easily. Yu complains that Crowley is way stronger than before, but Crowley says he held back at that time. When Narumi asks how a thirteenth progenitor could defeat a tenth progenitor, Crowley reveals his strength is actually closer to a seventh progenitor, and he’s been hiding his strength for the past 800 or so years.

When Mika gets Crowley to reveal that was all due to Ferid’s scheming, Mika repeats that Ferid cannot be trusted. Crowley says he agrees that dealing with Ferid is a pain in the ass, and he suggests they forget about rescuing them. Yu says they already decided to rescue him and says he has things he needs Ferid to tell him. He says he also owes the queen for saving his family.

Since they have decided, Crowley tells them they must get stronger quickly since they had difficulty fighting a tenth and must face a fifth progenitor in order to rescue Ferid and Krul.

Yu interrogates Crowley about being a human, surprising the others by his lack of fear. The two of them walk into the mansion while the others remain outside. In the mansion, Crowley finds an envelope with Ferid giving his next instructions in the form of a riddle. Crowley sighs

and tries to work it out, so Yu takes the opportunity to attempt to strike Crowley from behind. Crowley blocks it with ease and knocks Yu's sword into the ceiling. He criticizes Yu's lack of technique. Yu attempts again, but Crowley holds his sword back with ease and scolds him for having so much wasted movement.

Yu asks Crowley about his past, and Crowley says he was a crusader fighting in a holy war. Yu nods along, and Crowley says that Yu does not know history after all.

When Yu says it is not right for a former human to kill humans, Crowley points out that nothing kills more humans than humans. He says he killed far more humans when he was human compared to after he became a vampire.

Crowley gives Yu the riddle, and Yu tells him the answer is a candle. Crowley praises him for being smart. He finds an envelope under a three-pronged candelabra.

The rest of the team arrives, and they ask about food. Crowley directs them to the kitchen. Yu realizes Mika should be thirsty right about now, but Mika holds up a hand.

Ferid's note says that the remains of Yu and the others' family members are kept in the cellar It warns him to restrain Yu if he goes berserk and to protect his newfound friends. Crowley wonders about these "friends" and glances at the humans with a troubled expression. Yu asks him what is wrong, and he says it is kinda tough to be given friends for the first time in 800 years.

Crowley tells Yu to go eat before they go into the cellar. Yu asks what is in there, and Crowley says he will tell them after they eat.

While the group is eating, Crowley goes to check out the basement on his own. He finds another letter addressed to him. The letter warns him that Ferid laid a trap that will be activated if Crowley tries entering the basement without having a human with him. Despite the initial warning, Crowley's curiosity makes him open the basement door. A loud 'clunk' is heard and the group hears his scream across the mansion. Crowley re-enters the room dusty and annoyed. Having heard his scream, the group asks if he's okay and he explains that he was the victim of a petty trick. After that, he explains what they can expect to find in the basement, he does this to prevent Yu from going berserk out of shock. Yu still wants to go with everyone, Crowley settles the unease of the group by saying he'll chop of Yu's limbs if he loses control.

Once everyone is in the basement, Crowley pauses to stare intently at a person inside the preserving tubes. Shinoa notices and asks him if it's someone he knows, Crowley answers a negative at first, then admits he sort of does and says that Ferid is very twisted. When Shinoa questions him if he wants to bring them back to life, Crowley says that he's a vampire and thus he doesn't have that desire. He also mentions that help will arrive soon, some of her old friends.

With Guren now present, Crowley stands by mostly in silence. He notices Shinoa's unease and asks her what's wrong. When Mikaela attacks Guren out of rage, Crowley wonders to himself how much longer he will hold that passion.

Crowley is present as Yuu learns how to control his Seraph, He provides information at times.

A flashback to the plan shows Crowley pointing out that there's no chance of their group defeating Ky Luc without anyone taking a hit. He foreshadowed the 5th progenitor's cold logic and cunning nature, meaning that he will see through their plan and will likely even be amused.

When the group attacks Ky Luc, Crowley is in the constant lineup of attacks. He helps out Norito Goshi by attacking Ky Luc but is decapitated in the process.

The next time we see Crowley, his head is reattached and healing. He throws a sword to Ferid, who has been cut in half and escaped the flame torture. Ferid gets decapitated by Shinoa shortly after being healed and Crowley throws his head back to him. Crowley questions Ferid about the torture and Ferid questions back if Crowley was worried about him. Crowley wonders to himself that maybe he was, since Ferid is the only one for him to worry about. The two joke around a bit more, admitting their jealousy of humans for being alive, they look at Yuu's group with smiles.

Crowley points out that they will definitely be branded traitors now and asks Ferid what's next on the agenda. As Ferid responds vaguely, Crowley asks him who they are going to fight. Ferid says they will be fighting a god.

Shibuya Arc
Listening to Guren and Kureto talking, Crowley asks Ferid beside him whether the Saito they mentioned is Rigr Stafford. He asks Ferid where they are going when he leaves for them both to check in on the first. Following Ferid into the examination room where Shinoa was moved to, Crowley asks if Ferid really does know how to stop her transformation into a vampire, and again asks how. He looks on in shock upon discovering that Ferid's simple solution is to draw his sword and kill the person before the transformation is complete.

Upon Ferid’s signal, Crowley grabs his head and nonchalantly flings Ferid away from Shikama Doji who manifested to defend Shinoa from his attack. Crowley fights against an onslaught of attacks noting it is hard. He turns to clarify if they should run away, with Ferid missing his legs at which point Crowley promptly has his head cut off and his body falls to it’s knees. He manages to stand, pick up and reattach his head as he listens to Ferid questioning the first’s motives.

With the first leaving to investigate a surprise attack from the Hyakuya Sect on Shibuya, Crowley arrives on the walls and gains one of the attackers attention. Crowley is recognised by Basteya Irclu as he tells them he thought they were dead. Crowley asks why they are here, and that it is a good question when Basteya asks the same of him.

After Ferid's failed ambush on the sixth progenitor, Crowley is mentioned as one of Ferid's allies. When discussions fail, Crowley uses his sword to deflect heavy fire on the wall before suggesting to Ferid that he stop standing there daydreaming and maybe protect himself. Crowley is not too keen that he has to protect Ferid since he is thinking right now.

As a result of a member of the Hyakuya Sect using Jigenso to redirect Shinya's Byakkomaru projectile, Crowley turns to the attack appearing behind him for it to blow up directly in his face. Mito calls out the Hyakuya soldiers that have scaled the walls, and Crowley sweeps them away with a swing of his sword. Calling to Ferid that he just got a scratch, Crowley asks whether he has collected his thoughts yet but is uncertain of what the "Mr. Handy-weapon man" Ferid refers to is.

Watching the fight between the first and Saito, Crowley thinks that Ferid has been pretty occupied with looking up at dad. He questions what type of complex Ferid really has, and replies that his lolita complex answer is not funny before asking what do they do about this situation. He asks inquisitively who their ally is that Ferid mentions, and again who "Mr. Namanari" boy is. Standing amongst the stabbed and unconscious Hyakuya Sect members, Crowley notices and comments on Ferid appearing in a good mood. He remarks further that if one were to look through the whole city and pick the person in the best mood in these crummy circumstances, then it would definitely be Ferid. Asking what Ferid is nervous about, Crowley thinks it was stupid to ask a serious question considering his response. He asks what the knife Ferid is balancing on his finger is used for, remembering it as the one he took out the child who had been turned into a seraph. Hearing that Rigr wants the instrument, Crowley asks Ferid what he wants it for.

Walking calmly as the Hyakuya Sect retreat having completed their mission, Crowley confirms that he is thirsty having done a lot of exercise today, before he sees Ferid take ahold of a Hyakuya Sect operative. Asked whether he wants the blood of the Imperial Demon Army soldier who Ferid just rescued, Crowley replies did Ferid not just say they were allies. Understanding Ferid saying that the blood of allies just betrayed is tastiest kind, Crowley mentions how Ferid guzzled his down back in the day. Told to turn back into a human for Ferid to try it again, Crowley states to not ask for the impossible. He advises against Ferid trying his blood anyway, or Crowley will drink Ferid's blood.

Gulping when Ferid mentions to actually drink his blood to kill him, Crowley breaks the silence with asking him to stop the jokes now and to do what they are here for. He has noticed the smell of the same blood in their veins and darkly observes that it is father's blood. He joins Ferid down an alley where the drag marks of many chains lead and comes across the upper torso of Saitō, with his left arm gone and the chains coming out from his body. With Ferid asking what he thinks of the point of killing Saitō, and that the father's duty is to teach the sons what the point of living is, Crowley replies that Ferid force fed him a vial of father's blood. Technically Ferid made him a vampire and Crowley says does it not mean that Ferid is supposed to teach him, rather than Saitō. He does not remember Ferid being the picture of familial responsibility.

It is recalled how those important to him were killed when Crowley was human, and yet despite that nothing changed. Crowley listens to Ferid's views on living until commenting on how fast it was when Saitō leaves a faint scrape across Ferid's cheek. Indifferent after the explosion in the alley, after the dust has settled Crowley is in disbelief that Ferid was a prince as he continues to speak with Saitō. He shares Ferid's view with a voice offering help heard and shouts to Ferid that there is trouble. He catches Ferid's chain clad arm as it is sliced off and catches the dismembered arm that is still gripping the sinful key. Crowley does not have a good feeling about this, and the fears are grounded since Urd Geales, Lest Karr and Ky Luc have joined them. Once Saitō accepts Urd's offer of help, Crowley uses his sword to defend against the attacking second progenitor. Shouting to Ferid as Urd raises his sword, Crowley blocks and bears the brunt of the strike.

Not doubtful that Urd could cut through his sword if he wanted, Crowley questions Ferid on what they do now. He is shocked that Ferid rejected the chance to surrender and says to wait as Urd powers his sword. With Ferid cut in half Crowley seizes Ferid's arm that is holding the sinful key then leaps upwards taking Ferid's upper torso as well. Surprised that Ferid's UV-blocking rings are on the other half of his body, Crowley takes ahold if him again and says they have to run. Questioning whether Ferid is trying to die today, Crowley is requested to throw him down twenty-three degrees diagonally to the left of here.

In the air he complies after hearing they might win if they are lucky. Crowley is stood in the alley behind Urd and receives the sinful key thrown to him by Ferid who used Jigenso's portal to join them. Activating the key, Crowley agrees they definitely need to end it here. Pained by a loud window shattering scream, Crowley wonders whose is it. In contrast to Ferid's merriment, Crowley says he is not having much fun at all. He takes Ferid and escapes the scene.

Natural abilities
As a vampire, Crowley is naturally much stronger and more powerful than a human. Some characters described him as being a monster in terms of power. Being a Thirteenth Progenitor, he is very strong even among vampires and stronger than lower ranking vampires. He can easily regenerate from non-curse wounds. As a noble, he also has permission and the ability to turn someone into a vampire if he so chooses. Further prove of his strength is that he is capable of becoming seven progenitor vampire but simply hiding his true strength as thirteen progenitor under Ferid orders. This was shown when Crowley Eusford easily defeat tenth progenitor Fuola despite him being Thirteen progenitor and ranked lower than Fuola.

Crowley displayed his strength to superhuman levels. During the battle at Nagoya, he's even capable of catching the manifestation of Yoichi's Gekkōin directed after him - unharmed.

He can also move at superhuman speeds, as he demonstrated to Yu outside Shinjuku by getting behind him faster than the he could've possibly followed. From his past as a knight, Crowley is an exceptional swordsman. Superior physical abilities aside, he is a superior swordsman to Yu, lecturing him on his lack of technique.

Crowley, in both the light novel and the manga, is shown to be a patient teacher. This is apparently because he used to train soldiers back when he was still a human.

Crowley is shown to be quite adept at fixing vehicles, stating that he's forced to learn it because Ferid is not capable of fixing vehicles himself.

Equipment
He wields a first-class vampire sword. It drinks his blood by piercing his hand with spikes that pierce his palm and go through the back of his hand.

The sword has a distinctive knuckle guard and quillon and appears to be designed for two hand wielding instead of one.

Seraph of the End: Vampire Reign
"Whoa! Wow. Not bad for a bunch of humans. Who are you?"

- Crowley to Shinoa's squad upon getting his arm cut off by them.

"I'll let you go this time. But next time... I'm going to enjoy sipping on your blood. See you later, my cute little lambs."

- Crowley to Shinoa's squad when he receives orders to join Ferid Bathory.

"Cattle don't talk."

- Crowley to Shinoa Hiragi while pinning her down on the battlefield at Shinjuku.

"What the heck? Looks like something dangerous..."

- Crowley when Yuichiro Hyakuya transforms.

"Once those humans get here, I hope things will get more interesting."

- Crowley to Horn Skuld and Chess Belle.

"It's okay. One or two doesn't matter. It's not like a human life is worth much. After all, we've got others."

- Crowley when Chess accidentally kills a hostage.

"I was just wondering if the humans might be getting a little too powerful, too fast. See... Humans have always had a lust for power, even if it meant delving into the forbidden to get it. But were they ever this strong before? It makes me wonder. Is someone, somewhere... giving humans information they have no business having?"

- Crowley to Horn and Chess.

"Ha ha! You were the ones who attacked first, and now you don't want me to follow? You humans are always so selfish."

- Crowley to Guren and Shinya.

"You're a tough one. Well then... I just might have to use both hands."

- Crowley against Yu after Yu takes three pills.

"That's easy. 'Cause you're just livestock. You humans eat cows and pigs. Do you live in fear of them revolting someday? No. In the end... No matter what you do, we will never fear you."

- Crowley's response when Yu asks why he is not strong enough.

"Whoa! I knew it! Getting involved with Ferid's plans always means something interesting will happen. You're so lively and full of energy that I want your blood now. Sorry, Ferid... Next time he gets close, I might just drink him dry."

- Crowley after Yu becomes possessed.

"Him? That brash human? He sure doesn't look it."

- Crowley to Ferid Bathory after Ferid reveals the plan in Nagoya was all Guren's doing.

"I haven't seen Ferid in such a good mood in ages."

- Crowley to Chess and Horn.

"You'' have friends?"

- Crowley to Ferid.

"I never trusted you with anything, ever."

- Crowley to Ferid.

"Did you really mean what you just said? You do remember that you killed Yu and Mika's entire family once, right? For fun."

- Crowley to Ferid.

"Whew! Finally caught up. Okay. Until Ferid shows up, let's have some fun."

- Crowley to the main group.

"Oh, nice. If you fight with me, that'll make waiting for Ferid less boring."

- Crowley to the main group.

"Uh, actually... I'm not after anything in particular myself.""

- Crowley to Yu after Yu surrenders to him.

"Too bad. I feel for you lot... Hanging out with him with all his antics is exhausting."

- Crowley to Shinoa Squad about Ferid.

"I learned because you keep making me repair your classic cars."

- Crowley to Ferid.

"Precious, my ass... I didn't ask you to turn me into a vampire, you know. I've been mad at you about it these last 800 years.... Not only did you turn me, you went out of your way to have me drink some other vampire's blood. Whose was it again?"

- Crowley to Ferid.

"So that means we're siblings. Yet I've never met our father, and I don't know what my brother is really up to. Are you doing all this just to get back at him? If you don't tell me, I'll decide it's you I want my revenge on instead of him."

- Crowley to Ferid about Saito.

"Was that spectacular enough for you?"

- Crowley to Ferid after sending Ferid flying through the windshield of the bus.

"Uh, no. Trying to kill that thing would be impossible."

- Crowley to Ferid about Saito.

"We can't rescue them. Not right now, anyway. Still... This is amazing. Ferid is actually screaming."

- Crowley to Yu.

"A battle formation, huh? Man, that takes me back. I used to do the same thing a long time ago, when I was human. I know! What say we test it? Let's see if you and Mika, in that little formation of yours... can actually stop me."

- Crowley to the Shinoa Squad.

"Oh, that? The 'thirteenth progenitor' thing is all just a front. In reality, my strength is a lot greater than that. I'm closer to seventh progenitor."

- Crowley to Shinoa Squad.

"Turn a human using the blood of a seventh progenitor, and you'll usually get a vampire that's powerful enough to be classed as a thirteenth or fourteenth. But when Ferid turned me, he didn't use his own blood. He had me drink a second progenitor's. That puts my real power at about the same level as his... seventh or eighth. Keeping it a secret is an advantage for me. See, all the upper-level progenitors I know think I'm a thirteenth.... So, if we fight, they underestimate my strength."

- Crowley to the Shinoa Squad.

"You have the speed, but your lack of technique is holding you back. Study even basic swordsmanship, and you'll get much better."

- Crowley to Yuichiro.

"When I was human, huh? Hnn... That was an awfully long time ago. You familiar with history? Okay then. This might surprise you, but I was a crusader. A knight fighting in a holy war for the sake of God, who's now fallen so far as to become a vampire. It's funny when you think about it, isn't it?"

- Crowley to Yuichiro.

"Are you serious? Just look at history. Nothing kills more humans than humans. I killed scores upon scores of humans when I was still human. In fact, compared to that, ever since I became a vampire, I practically haven't killed any."

- Crowley to Yuichiro.

"Uh, well... It's kinda tough being given friends for the first time in 800 years, is all."

- Crowley to Yuichiro.

"Oh? So this time, you'll destroy the whole world for your ego? What amazing greed. You sound just like a demon."

- Crowley to Yuichiro.

"But he's a vampire. Vampires don't grow to like anybody. They can't."

- Crowley's thoughts when Yu says Mika will come to like Guren.

"I've seen him a few times and each time he always looked like he was amused. Amusement is an emotion. Emotions are unusual for vampires. Plus.. He's a little like Ferid in that way. He has a vampire's typical cold logic mixed with a dash of madness. I'm sure he'll figure us out, and it is will amuse him."

- Crowley talking about Ky Luc.

"It's always easy to hold back the thirst... until it suddenly isn't."

- Ferid to Crowley.

"Yeah. Now that you mention it, I am a little thirsty. I did a lot of exercise today."

- Replying to Ferid and his views after the Hyakuya Sect invasion.

"Sinful key. Engage."

- Having caught the sinful key thrown to him by Ferid, Crowley verbally activates the device and targets vampire progenitors Urd Geales, Lest Kar and Ky Luc.
