Mahiru Hīragi

Mahiru Hīragi 「柊 真昼, Hīragi Mahiru」 is the love interest and demon weapon of Guren Ichinose. She is also the main female character and plays an important role in the Seraph of the End: Guren Ichinose: Catastrophe at Sixteen light novel series.

Mahiru was the next successor of the Hīragi Family. She stole Krul's brother, Asura, from her and used him as her own demon weapon. She would eventually turn herself into a demon and was sealed within Guren's weapon, becoming a cursed gear called Mahiru-no-yo.

Appearance
In the light novels, Mahiru is described by Guren and many others as a beautiful young girl. She has long ashen (blueish-gray) hair with fringe and amber eyes. Shinoa Hīragi have commented that her sister is taller and way more voluptuous than herself. When she was a namanari, Mahiru displayed no distinct physical features that showed the demon was in control except for a red glint in her pupils. After becoming a vampire, her eyes became red and grew fangs.

In the anime, Mahiru is portrayed to have a more saturated hair color, and the size of her breasts are toned down more.

She is usually seen with the First Shibuya High School uniform, a sailor fuku, which consists of a blouse with red trim around the collar with a grayish blue sailor-style collar which also has red trim and a similarly colored skirt with a belt. The red uniform ribbon which is thinner than normal sailor fuku, is attached to the bottom right end of the collar. The school's emblem is located on the right breast. She wears thigh length grayish blue stockings and dark blue dress shoes along with it.

Human
Mahiru was a very popular member of the Hīragi Family, and she was famous for treating the other clans with kindness and equality. When she was five years old, she rebelled against her family and makes contact with Guren Ichinose, who she soon falls in love with. Her great intelligence and skill made her father favor her, but she hated the Hīragi Family.

She appeared to be less cold-blooded or ruthless than her siblings, saving Sayuri when Seishirō beats her and attempted to strip her. Unlike her brother, she did not seem to enjoy picking on the weak.

She has many expectations on her and does battle with the demon born inside her. In her desperation to save Shinoa, who also had a demon inside her, Mahiru took Shinoa's demon and sacrificed the rest of her humanity.

What's left of Mahiru's human side is often seen wrestling for control with her demonic side in the Light Novels. Whenever Guren is injured, such as when he sliced off his own arm to stop the spread of the demon's curse, Mahiru's human side is able to resurface briefly, crying as she desperately tries to reattach Guren's arm.

Namanari
Mahiru is in this state for most of the Catastrophe light novels. The demonic side of her gradually takes more and more time in control of her body, and twists her love for Guren by starting his transgression into demonhood as well. Her need for power to protect and be with Guren warps into a desire to either rule or destroy the world.

Mahiru-no-yo laughs often and loves to mock Kureto and the other characters. She has no sympathy for anyone, and is willing to kill anyone who stands in her path. She is absolutely delighted when Guren shows his strength or touches her. However, she has no sympathy or compassion for anyone, including Guren, unless her original human personality breaks through.

Since the human and demonic personalities are in flux, they can be seen arguing and fighting for control when Mahiru-no-yo puts Guren in danger.

Vampire
Mahiru's personalities no longer fluctuate, and she expresses both the haughty playfulness of her demon side and the hopeless love of her human one. She is now consumed by lust for blood, especially Guren's. She enjoys feasting on people's blood and drinking them dry.

Demon
The human personality of Mahiru has completely been consumed by Mahiru-no-yo. The fact that she became a possession-type demon suggests she is particularly violent. The demon helps Guren grow into a namanari and possesses him as needed to make Guren's demonic side take control.

History
Mahiru along with her younger sister, Shinoa, were conceived through artificial insemination using the seed of Tenri Hīragi in demon-possessed women. Eventually, the Hiragi had her mother killed, so she attempted to anger them by becoming close to the Ichinose, where she encountered Guren. Shortly afterward, the two fell in love. They were violently separated for the next ten years.

When he was ten years old, Shinya had been selected by the Hīragi family to be the potential mate for Mahiru, and he was adopted into their family to this end. This was a plan by the Hīragi to keep their bloodline strong. However, when Shinya and Mahiru first met she told him she wouldn't fall in love with him as she already had someone. Had she openly stated to her family she didn't want Shinya, they would have disposed of him; and she wasn't allowed to be with Guren, whom she loved. For these reasons, they both agreed Shinya would be her cover-up fiancé until she could be with the person she loved.

Growing up, she saw visions of the future and even prophesied the end of the world on Christmas Day 2012 as God's punishment against human ambition for meddling with the taboo. The trumpets of the Apocalypse would sound, and the Seraph would descend.

Later on, her research on demons eventually turned her into one until Guren killed her. She became the demon within his Cursed Gear and part of the Black Demon Series.

Book 1
In the prologue, Mahiru asks Guren if they can get married when they are older. Guren says they cannot because she is from the head clan while he is from a minor clan. Their stations are too different. People come looking for Mahiru and beat up Guren before dragging her away. This leads to both of them yearning for power as a decade goes by. Mahiru and Guren would cross paths again at First Shibuya High with the latter finally seeing the former give the freshmen address. At the school, Mahiru and her brothers are the most popular and respected by the student body due to their power and family status. After Shinya puts Guren in the nurse's office, Mahiru comes to visit him and reconnect after many years, but he treats her coldly. During the qualification exams, she saves Sayuri when Seishirō severely beats her and begins to strip her. Sometime later, the Brotherhood of a Thousand Nights attacks and kills many students and teachers. While fighting Saitō, Guren and Shinya learn that Mahiru betrayed the Hīragi Family by joining with the Thousand Nights. Mahiru then turns up and attacks Guren with a black katana. The two fight with both proving able in holding against each other.

She then reveals that her sword is a cursed gear, a demon possessed weapon that she and the Thousand Nights were able to successfully create and, with the combination of the Thousand Nights and Hīragi magic, were even able to make contracts with bind high-ranking demons. She tries to convince Guren to join her when she suddenly stops mid-sentence and becomes pained. She is able to get out to Guren that the demon has possessed her and that the cursed gear experiment is actually a failure before denying that that there's anything wrong.

The sword then begins affecting her right arm which prompts Saitō to tell her that they need to go. Angered by the dressed man, Guren lunges at Saitō only for Mahiru to intercept his blade which cuts his sword, Kujakumaru, in half. Mahiru gives Guren one last chance to come with her which he refuses as his quest for power is different from hers. She then tells him about the apocalypse happening on Christmas and will meet again when the world comes to an end. Before making her leave, Mahiru tells Guren she loves him and promising that she will be waiting for him when he needs her again.

Book 2
During their investigation of Ueno Zoo, Guren Squad battle a tiger like creature that was made with genes from the Horsemen of the Apocalypse. When the squad was about to retreat after due to Guren's wound, Mahiru turns up and knocks Mito, Norito, Sayuri, and Shigure unconscious in moments. Shinya was able avoid her strike before Mahiru was able to grab him by the neck and choke him to unconsciousness. She tells Guren that she plans on betraying the Thousand Nights as her loyalties lie wherever there is power. When Guren asks where that power is, Mahiru says that its in depravity and madness which lives deep in the heart, and that Guren should follow that path as well.

She then thrusts the black katana into the ground with its curse affecting Guren. Mahiru encourages him to take the sword to slay the chimera before stepping back to watch. When Guren reaches for the sword, Mahiru suddenly cries out to him to stop and not lose his humanity before telling herself to be silent and hitting herself in the chest. This stops Guren momentarily when he asks Mahiru which one is the real her, which leads her to ask if it had anything to do with his choice. After that, Guren takes the cursed gear which causes a demon to sprout inside him. Mahiru is ecstatic when Guren makes quick work of the chimera, and goads him into killing his friends and joining her. Guren was about to do just that when his other hand used his sword, Hoarfrost, to severe the lower part of this arm that was holding the demon blade. Mahiru quickly gets that limb and holds it tightly to Guren's arm so the demon's regenerative ability can reattach the arm. Mahiru then becomes desperate and becomes tearful when the regeneration process isn't working fast enough. Guren tries to convince Mahiru that there could be another way and for her to stop this cursed gear research, only for her to reject him and getting her offer rejected in return. During their talk, Guren's arm fully reattached itself, and Mahiru promises that he will fall just like her. Ferid Bathory out-matches them without any effort and takes half of the chimera with him.

Book 3
In the prologue, Mahiru meets her victorious fiancé candidate, Shinya Hīragi, for the first time. She informs him that she will never love him because she already loves Guren, but he will have a fake relationship with her in order to protect Guren. Shinya says he does not plan to lose to Guren, and they fight briefly where Mahiru tricks him with an illusion before putting an exploding tag onto his back.

In the present day, Kureto pretends to torture Shinoa while interrogating Guren. Mahiru sends Kureto a message telling him to do as he pleases, and tears briefly form in Shinoa’s eyes. Kureto sends the IP address to Guren, and Guren sends a message to Mahiru. Mahiru calls Guren, and he puts the phone on speaker. Guren, Shinoa, and Kureto all speak to her. Shinoa says everything went as Mahiru predicted. Mahiru twists the conversation and repeatedly states that all of the events occurring since the first Catastrophe volume are his doing. She reveals the special ops he sent after her just now are already dead. A student rushes in and reveals that this entire conversation was just broadcast over the whole school.

After Kureto releases Guren and Shinoa, Mahiru calls him again. She says she only wants to hear his voice and says the demon was in control before. They establish a rendezvous at 5:30 p.m. in apartment 501 located fifteen minutes from Ikejiri-Ohashi Station.

Guren reads about the demon experiments ongoing in Mahiru and Shinoa. The research notes reveal Mahiru and Shinoa’s origin and how the demon’s will drastically increased when Mahiru hit puberty. To prevent Shinoa from suffering the same fate, Mahiru joined the Thousand Nights and used herself as a test subject.

Mahiru does not arrive until 7 p.m.

Although she tells Guren he cannot save her, he insists he can, and they have sex that evening. She tells Guren that he wants to protect his own comrades rather than her. Mahiru reveals she now has both her demon and Shinoa’s demon inside her body, which has sped up the rate of her degeneration. She shared part of the demon with Guren before in order to remove all of the demon from Shinoa, so he will eventually become a demon as well. When he asks to fight by her side, she tells him there is not enough time and reveals the Apocalypse occurring that Christmas.

The vampire who chased Guren and Shinya the previous night enters through the balcony and greets Mahiru, but Mahiru calls upon Asuramaru and quickly kills her.

Mahiru reveals she fabricated information to set the Hīragi House and Thousand Nights against each other. Guren says he refuses to let her give up her humanity. Mahiru jumps out the window. When Guren learns that the Thousand Nights is attacking the school and leaves shortly afterward, he comes across a running motorcycle and a demonic sword waiting for him in an alley that were presumably left behind for him by Mahiru.

Book 4
Mahiru has an illusion over the whole school and is responsible for instigating the conflict between the Hiragi and the Thousand Nights.

Mito, Shinya, and Goshi play video games at Guren’s apartment until Mahiru shows up. Guren attacks her causing them to fall from the twenty-fifth floor. Mahiru stops her fall by using her sword while Guren is badly injured but recovers.

Book 5
Mahiru visits Yuichiro Hyakuya, who is being experimented on and abused by the Hyakuya Sect. She asks him about his reason to live and if he has no right to live if he is a demon which Yu does not know how to answer. Since his mind has not broken from his experiences, she tells him he will find an answer one day. A researcher says he will erase all memory of this conversation from Yu’s mind. She asks about receiving one of the Hyakuya orphans to experiment on with cursed gear.

Kureto calls Mahiru and tells her in explicit detail about how he will torture Guren, but she only laughs and says she is going to Kyoto. Mahiru visits one of the Hyakuya Orphanages with the pseudonym Miyuki Yamada. She chats with Akane Hyakuya and realizes she has a crush on Mikaela Hyakuya, one of the subjects with a body well-suited to experimentation. She “adopts” a child named Juni before taking him to a van on the opposite side of the street, killing the driver, and knocking Juni unconscious. She enters the freeway but is attacked by vampires. She fights them, but they cause a large car pile-up. The vampires capture Mahiru and take her to Kyoto.

Mahiru is tied to a cross deep within Sanguinem and is being tortured. Krul Tepes asks her if she is ready to talk and reveals the date is already December 20th. Mahiru summons Shikama Doji and breaks free. Krul asks Mahiru about Asura Tepes, but Mahiru only laughs.

Book 6
The prologue shows Guren and Mahiru’s first meeting when they were five years old. Guren is training late and night and jumps into a river to cool off. Mahiru appears and claims to be a forest fairy, but Guren points out that they are in the mountains. She reveals that the Ichinose are the reason her mother died. On December 2nd, Mahiru leaves Sanguinem as a vampire sired by Krul. Saito gives her a ring to protect her from sunlight, but she attacks him with Shikama Dōji. Mahiru knocks out a human woman and drinks her blood, noting that it tastes different depending on the age and sex of the human and that the blood turns bad once the human dies. Mahiru then returns to Tokyo.

On December 10th, Kureto sends in Guren and his gang to take care of students that have become possessed by demons at the school. Guren arrives first and knocks out one demon-possessed boy when Mahiru appears and applauds Guren’s strength. She admits this was her doing and asks about the experimentation on Asuramaru. She says a human must be modified in order to use a Black Demon, but the current success rate is less than 20%. Guren says he wants to protect both her and his friends and asks that she surrender, so he can extract the demon from her. She throws down Shikama Dōji and instructs him to give it to Shinoa in order to protect her. The rest of the group arrive and attack Mahiru, but she escapes.

Guren calls Mahiru and says he will betray the Hīragi and join her. She laughs.

Story: Vampire Reign
Although she is present as Lieutenant Colonel Guren Ichinose's weapon from the moment Guren appears in the manga, readers first see her human appearance at the beginning of chapter 17 within his mind. She wants him to seek more power. When he addresses her, she says she's glad that he came as she wanted to meet with him.

Post-Shinjuku Arc
In the following chapter, Guren reveals her form during a fight with Yu. After hearing Guren summon his demon by calling out her name, Shinoa holds her scythe at Guren's neck. She reveals that her weapon specializes in long-range combat and consequently stands no chance against a melee fighter like Guren at that range. Guren calmly says he would let Shinoa kill him. Shinoa asks him if that is his way to atone for killing her sister, Mahiru. She asks if she is in his sword since she heard him call her name. Guren says that Mahiru is already gone since she turned into a demon and saved the world by completing Cursed Gear. Shinoa laughs, stating that Mahiru was never one to care about the world because she loved him. She longed to be with him since they could never be together and became obsessed with demons.

After discussing the events of eight years ago, Shinoa says that if Mahiru hadn't completed the development of Cursed Gear, humanity would have perished. Her sister, who was just a girl in love became something like a Messiah. But then she was killed when she became obsessed with her research and became a demon. She continues saying, the one who killed Mahiru was the person who used to be her lover, him, Guren.

Shinoa asks him if Mahiru is together with him inside his sword, stating that he is being possessed by her. Guren asks her if they ever got along. She explains that she was not close with her sister because Hīragis are raised without knowing familial love.

Shinoa asks if making use of Yu was one of Mahiru's orders and asks if her sister or the demon for lack of a better word inside his sword is ordering him. She then asks him to stop what he is doing if his goal does not benefit Yu.

Guren tells her that Mahiru is dead and isn't coming back. He says that the demon inside his sword is under control so he isn't being possessed by her. But Shinoa doesn't believe him.

Nagoya Arc
In chapter 23, she appears and whispers to Guren in order to make sure he follows her rather than Lieutenant General Kureto Hīragi.

She appears again in chapter 38. She possesses Guren and kills the noble beating him. She uses Guren's body to point a sword at Krul Tepes and states that Krul will help her conduct an experiment on the Seraph of the End at Nagoya Airport.

Natural Abilities
As a human, Mahiru was shown to be a very good fighter, her movements quick and graceful. Guren noted that in terms of fighting, she might be even more skilled than Shinya, who's considered one of the best fighters in the school. Not even Seishirō would dare challenge her to a fight, despite his bellicose and arrogant behaviour. This shows just how much Mahiru outshines the rest of her class in terms of fighting.

Noted by Kureto and Shinoa, Mahiru was also intelligent and a genius. She's one of the early pioneers of the Cursed Gear, which is essential for mankind's survival ever since the Apocalypse. At a young age, Mahiru is able to extract the growing demon inside Shinoa, but at cost of her own humanity. She is credited for completing the Cursed Gear and hailed as a hero.

In Seraph of the End: Guren Ichinose: Catastrophe at Sixteen, upon losing her humanity right after transforming into a vampire, Mahiru noted to herself that she has finally managed to obtain strength, which is equal to a third progenitor like Krul Tepes. Whereas a vampire's power is dependent upon both age and lineage, it's unknown if Mahiru was really as powerful as she believed to be. This was because of Mahiru's was still young being in her late teen, in comparison to Krul, who has lived for a really long time.

Unlike Mikaela, who also became a true noble vampire by Krul, Mahiru doesn't seemed to have a first-class vampire weapon in possession, but still used the demon weapon, Shikama Dōji with its forms and abilities instead.

Upon discarding it, Mahiru can truly unleash her potential power as a true noble vampire, which is greater than that of a demon she originally became before the events of Seraph of the End occurred. Even so, despite the tremendous power she has greatly attained from Krul, it was still not far from enough to even scratch the second progenitor, Saitō and defeat him.
 * Demon's Thrall: Mahiru-no-Yo may enter her host's mind and consume him with illusions in an attempt to break his will. If she wins, she gains control over his body.


 * Basic Form: Mahiru-no-Yo appears as a black katana with a red streak down the middle. Merely drawing her increases her bearer's physical abilities significantly and calling upon her name increases them tremendously.
 * Namanari: A human one step from becoming a demon. Mahiru-no-Yo has managed to turn Guren into one of these. In this form, Guren and Mahiru cooperate and have tremendous power. However, Guren's personality changes to a more demonic, heartless, and demanding one. It is unclear whether this is the demonic side of Guren that Mahiru began to create the summer before the Apocalypse when they were both human or if Mahiru is the one in control of Guren's body.

Cursed Gear
Asuramaru 「阿修羅丸, Ashūramaru, lit. "Perfect Asura"」: Asuramaru is a possession-type demon weapon of the Black Demon Series. It resides inside a black sword that Mahiru once used. Whilst in use, the blade developed a thick green aura. She could call upon Asuramaru to fully use its power to attack opponents.

Shikama Dōji 「四鎌童子, lit. Four-Scythe Child」: A manifestation-type demon weapon from an unknown series. It is strongest at mid-range. Her primary ability is to detect anything that comes within the attack radius of her scythe.

We can perfect this strength together.  We…we can—S-Stay away, Guren!  It’s too late.  Too late…  The demon, it’s already possessed me.  The cursed gear…our experiment…  W-We failed…  This isn’t me.

That’s the one problem with that sword…  The demon ends up possessing the wielder, turning his soul murderous and dark.  Don’t worry, Guren.  Killing these five should temporarily quench the sword’s thirst for blood.  Afterward, we can search for a way to control the cursed gear together.  If we work together, I’m sure the two of us will be able to perfect this power.   No one will be able to stand against us.  No one will ever get in our way again.

 * "Ha! Pretty words.  But are words all you’ve got to persuade me?  What about strength?  Why don’t you just knock the sword out of my hands, grab me in your arms, and make me listen to you?  That’s right.  Because you can’t yet, can you?  I’m so much stronger than you that it’s almost heartbreaking.  I guess that’s what makes me the hare.  Hurtling headlong toward destruction.  I’m still waiting for my tortoise prince, Guren.  Try and save me if you like, before it’s too late."—Chapter 7, Page 315

 * "Hmm… I’m not sure.  But whether Guren is strong or weak, my feelings for him won’t change."—To Shinya when he asks if Guren is as strong as she is, Prologue
 * "I’m pretty sure Guren is strong, though… He’s probably much stronger than me."—To Shinya, Prologue
 * --Do as you like.—An email from Mahiru to Kureto after he announces Shinoa’s death sentence, Chapter 4
 * "Hmm? I never knew Kureto had such a Lolita complex."—To Shinoa after Shinoa reports that Kureto threatened to have her raped, Chapter 4
 * "They won’t? I’m pretty sure that Father places much greater trust in me than he does in you, Kureto.  It isn’t hard to believe that a weak person would be jealous of a strong one.  Remind me, Kureto, which one of us is stronger?  I hate to break it to you, dear sweet brother, but I’ve never once felt jealous of you.  Do you see what I’m getting at here?"—To Kureto, Chapter 4
 * "I…just wanted to hear your voice…" she said. She sounded weak and exhausted, entirely unlike the Mahiru who’d been threatening Kureto moments ago.—To Guren, Chapter 4
 * "W-Wait!" Mahiru cried in a panic.  "Don’t hang up, Guren.  If you hang up now, we might never be able to speak again."—To Guren, Chapter 4
 * "No. It’s not like that.  I wanted…  I…  N-No…  Not yet!" Mahiru’s voice suddenly grew strained.  Her breathing became ragged. Guren had witnessed this before.  Several times, when they had met, it had seemed as if Mahiru were suffering from a split personality. When it had happened before, Mahiru had told Guren to run.  Away from the demon.  That she was already lost. It could all just be an act.  But if it wasn’t… —To Guren, Chapter 4


 * She sounded like she was in pain as she answered, "Yes…I had to call now…while the demon part of me was still asleep…"—To Guren, Chapter 4
 * "I want…" Her voice sounded heavy.  "I want you to kill me…  I’m in control of myself less and less every day.  I’m barely here at all anymore.  It has to be now, before it’s too late…  While I can still resist—"—To Guren, Chapter 4
 * "GUREN!!" screamed Mahiru. She sounded on the verge of tears. In fact, Guren had a feeling she might already be crying.  He could hear a faint, wet sniffling as she spoke. "It’s already too late…"—To Guren, Chapter 4
 * "I’m sorry, Guren. I’m so sorry." —To Guren, Chapter 4
 * "G-Guren." "…" "I love you, Guren." "…" "Please, let me die while I’m still capable of feeling this…"—To Guren, Chapter 4
 * While the researchers may have given up, the project didn’t truly end there.. Because one day, Mahiru began having dreams. Those dreams were dark.  Very dark.  In her dreams, a demon spoke to her and queried her from the shadows. —Reading about Mahiru’s childhood, Chapter 4


 * As the years passed, and Mahiru’s body matured… As her heart and her emotions, her vanity, her sexuality, and her need for recognition grew, the demon’s voice, too, grew louder.—Reading about Mahiru’s childhood, Chapter 4
 * Working with the Hiragis had never been an option. Going to them would reveal the presence of the demon in her sister, who would be subject to experiments without delay. Instead, Mahiru used herself as a guinea pig, engaging in a long and lonely fight.—Reading about Mahiru’s adolescence, Chapter 4
 * "I’m not human anymore, Guren… You can’t hold me.  I’ve lost that right.  I can’t be with you any—"—To Guren, Chapter 4
 * "You…don’t love me, do you? Of course, you don’t.  It’s been ten years, after all…  I’m not even human anymore…  How could…how could anyone love a vile monster like me?"—To Guren, Chapter 4
 * "Please, Guren…" she said, murmuring into his chest. "I want you to take me…  Will you sleep with me?  Even if I am a monster?"—To Guren, Chapter 4
 * "I don’t know… I don’t know anything, anymore.  I’m just so… so tired—"—To Guren, Chapter 4
 * "Heh..heheh," she laughed shyly. "I didn’t expect you to kiss me like that…  My heart’s beating so fast I think it might explode."—To Guren, Chapter 4
 * "Yes, I have. I ate Shinoa’s demon.  I was so desperate to save her that I swallowed it up whole.  But that turned out to be my downfall.  Once I had two demons inside me, I couldn’t hold myself together any longer.  Still…"  Mahiru stared at Guren.  "I might be broken, but I don’t think I’ll forget what we did today.  I love you, Guren.  And I thank you.  You finally gave me what I wanted. She spread both her arms out wide. "Thanks to this…the last bit of weakness left in my heart has finally died.  Mahiru, the pathetic little six-year-old girl who called you on the phone to cry about how much she loved you, has let go of her attachment to this world and passed away."—To Guren, Chapter 4
 * "I’m sorry for getting you wrapped up in all of this, though, Guren… I managed to get the demon out of Shinoa, but in the end I wound up splitting it with you.  Now, you’re going to become a demon, too.  I guess I still wanted to depend on you a little…"—To Guren, Chapter 4
 * "I already told you, the world is going to come to an end. It’s exactly what it sounds like.  The adults will be destroyed first, because they’re the most tainted and filled with desire.  When it happens, everyone in the world over the age of thirteen will die… "God is angry.  At us, for our greed.  At mankind’s vile nature and insatiable desire.  At the unspeakable research we’ve been pursuing. "The land will rot. "Monsters will roam the Earth. "Poison will rain from the sky. "The Seraph of the End will blow its trumpet, and this world will fall. "Mankind won’t be able to survive in the new world.  Not the weak, at least."—To Guren, Chapter 4
 * "Come, Asuramaru…" she said.—To Asuramaru, Chapter 4
 * "Behind killing everyone from the Thousand Nights? I concocted a rumor that the Hiragis did that.  Today, the Thousand Nights are going to get their revenge.  And then the Hiragis will get revenge against the Thousand Nights.  And then the Thousand Nights will—" Mahiru’s words were cut off by the sound of an explosion in the distance.—To Guren, Chapter 4
 * "It looks like it’s started. Until yesterday, I was the only hare in the race… but things are going to change today.  Everyone will need to become a hare.  Everyone in the world.  Make haste, make haste."—To Guren, Chapter 4
 * "I’m trying to be with you, Guren," Mahiru assured him with a smile. "To live with you, even if it’s in the next world.  Even if it’s in a world where mankind can no longer survive.  But for that to happen, we’re going to have to be demons."—To Guren, Chapter 4
 * "Haha. Look at how vile humans are.  Give them the slightest reason to doubt, and they tear each other’s throats out.  Is that the side you want me to join?"—To Guren, Chapter 4
 * "There’s one thing I know, though, Guren. You’re strong.  Very strong.  That’s why I love you.  Kureto can’t hold a candle to you.  If you ever get serious, the whole world will tremble at your feet.  Because human strength lies in naïveté, weakness, and vileness.  A demon’s favorite things."—To Guren, Chapter 4
 * All that she left behind was the darkness and her scent.—Chapter 4

Book 4

 * "You don’t have much time, Guren… If you don’t hurry, you’re going to be too late.  Mito Jujo is waiting for you in the audiovisual room.  She’s on the brink of death, and she’s hungry for you.  She needs it so much.  You should take her, Guren.  Just like earlier, when you took me."—To Guren, Chapter 2
 * "It’s okay," Mahiru whispered into Sayuri’s ear. "It’s only natural for humans to feel lust.  But you’ll never be able to get what you want.  Not in this world.  You just aren’t strong enough.  I’m the one that Guren loves.  Not you.  He’ll never love you."—To Sayuri, Chapter 2
 * "Ahaha. I love how you try to protect these humans, Guren.  I love how greedy you are.  How you try to have it all, and in the end wind up with nothing.  I love you so much, I want you to have even more of the demonic poison!"—To Guren, Chapter 2
 * "That doesn’t matter," she skirted Guren’s question. "What’s important now is that my brother, Kureto, is about to bring the cursed gear project to nearly 90 percent completion.  He’s going to create an antidote to save you.  People will be able to use it to wield cursed gear while still holding onto their sanity…  But greatness requires more.  Any plan put together by a rational person like my brother will always include a large margin of safety.  An approach like that will never aim high enough."—To Guren, Chapter 4
 * "Hang up on me now and I’ll make sure you regret it for the rest of your life," she said.—To Guren, Chapter 4
 * "Oh, Guren. You can’t just screw a girl and run."—To Guren, Chapter 4
 * "Kill me, so I can live on inside of you forever."—To Guren, Epilogue
 * "This makes me love you even more…but I’m afraid a lovers’ suicide is out of the question. I’m entrusting the future to you.  When everything is in hopeless ruins, I want you to be the last ray of light shining on the world."—To Guren, Epilogue

Book 5

 * "You look human to me."—To Yuichiro Amane when he says his parents called him a demon, Prologue
 * "But if you are a demon, or a monster, or whatever," Mahiru continued unfazed, "does that really mean you shouldn’t get to live?"—To Yuichiro, Prologue
 * "I am…" she answered. "I have my own battle to fight, so you’ll have to stay strong on your own.  You do that, and someday I’ll come back to let you out of there."—To Yuichiro, Prologue
 * "I don’t think any human living is worth anything," she said. Yu seemed startled. "No one is really important," she said. "Everyone is just a cog in the end.  Get rid of this or that cog, and the next one will be born soon enough to take its place.  But tell me, Yu, if there’s no real meaning or value to life, what will you live for?"—To Yuichiro, Prologue
 * "Ahh, you’re so adorable, Guren. Even in the situation you’re in, you still don’t know what to do.  You want to be kind to everyone.  You’re exactly the type of person who’s bound to turn to your demon for help.  And you’ll fall so much deeper, so much darker than I did.  You pretend that you’re good and just, but someday, when hope is gone and the future is lost…  Ahh, I can’t wait, Guren.  I can’t wait to see that happen.  But I think we’ve talked enough for now."—To Guren, Chapter 1
 * "Kureto, how about you let your adorable half-sister give you a little advice. If you plan to keep using that demon sword, you should know that always doing things the correct way will only make you weak…  As long as you stick to taking baby steps, you’ll never be able to stop me in time.  Justice?  Reason?  Cast off those chains, Kureto.  If you don’t, you’ll never catch up to me."—To Kureto, Chapter 1
 * I don’t know what it’s like to be loved by your parents, so I don’t understand that feeling, Mahiru thought.—Reflecting to what a child said about thanking her parents back when she was little, Chapter 2
 * "Junji," she said. "You don’t need to be scared.  We’re actually just an ordinary, happy family.  You’ll like it with us."—To Junji at the Hyakuya Orphanage, Chapter 2
 * Mahiru had thought the same way when she was little. That she had the right to be happy. But no such right existed. If you wanted happiness, you had to scratch it out yourself, tearing and screaming, from the jaws of death.—Chapter 2
 * "You think so? Maybe I’m just patient.  My dream, actually, is to be a nice, traditional housewife.  Long-suffering, you know?"—To Krul Tepes, Chapter 5
 * "Ahaha. The turtle has begun to run.  I’m going to have to make sure he doesn’t catch up to me," Mahiru muttered to herself.  But deep down, what she really wanted, really desired, was for that turtle to overtake her and put his arms around her.—To herself after Guren moves outside her predictions, Chapter 5
 * "Ahh, I can hear it again, that noise," Mahiru said in a singsong voice, as Krul stared on. "Tock. Tock. "The sound of desire. "The footsteps of destruction. "Someone cries out.  Man’s sins are too great. "Someone cries out.  Man’s pride has grown too large. "Like Icarus. "Like Babel. "The second hand continues to race. "Avarice marches onward. "Toward the end of the world. "Toward a world of blood. "This is the story of how man goes extinct once more."—To Krul, Chapter 5

Book 6

 * "Because they killed my mother… The Hiragi Clan hunted her down and killed her.  My father barely ever even looks at me.  So I decided to do the one thing I knew would bother the Hiragis the most."—To Guren about why she first approached him, Prologue
 * "I wonder how these bands are created… I’ll have to look into it and make my own."—To herself after tearing her UV-suppressing armband to pieces, Chapter 4
 * "Ahh, I must be thirsty for blood."—To herself while thinking of Guren, Chapter 4
 * "Not that I really qualified as human even before becoming a vampire," she remembered.—To herself, Chapter 4
 * "Are you that scared of me?"—To Guren, Chapter 4
 * "I came to protect what’s dear to me," she answered with a serious expression on her face. "…You… and my sister."—To Guren, Chapter 4
 * "Did you just peek up my skirt, Guren?" Mahiru asked, laughing. "You had that kick coming, you naughty perv!"—To Guren, Chapter 4
 * "I’m still in the lead, Guren. But you’ve gotten very close.  Hurry now, catch up to me and take me in your arms."—To Guren, Chapter 4
 * "Before we go any further, I need to tell you why I’m here. I’ve placed the cursed gear I dropped earlier, Shikama Doji, in your pocket.  Give it to Shinoa.  As long as she has it, she should be able to survive after the world ends…"—To Guren, Chapter 4
 * "Ahh… I love the way you smell, Guren. I wish we could stay like this forever."—To Guren while wrestling with him, Chapter 4
 * "Ahhh, I can’t hold back any longer," Mahiru moaned. "Just a little, Guren, just a little taste."—To Guren before biting him, Chapter 4
 * "You see? You haven’t caught up yet, after all."—To Guren, Chapter 4
 * "Are you calling to invite me on a Christmas date?"—To Guren, Chapter 4
