Crowley Eusford/Relationships

Ferid Bathory
Despite his unpredictable, secretive, and often cold treatment to Crowley, Crowley apears unfazed and unimpressed by the notion. Crowley follows and supports Ferid's faction because according to him 'Getting involved with Ferid always means something interesting will happen'. Crowley also considers Ferid a possible candidate to be sharing information with the humans. Crowley has actually known Ferid ever since he was a young crusader in the 13th century and it's very likely that Ferid was the one that turned him. They share a strange form of companionship and it;s unclear how close they truly are and what either of them truly thinks of the other. Despite that, Crowley goes along with any of Ferid's plans even before questioning the motives. Proven with how he helps Ferid in defeating Krul by acting as a distraction and later tagging along for car ride and only asking later what Ferid planned to do.

Chess Belle
One of Crowley's servants. Immature, playful, and jealous character. It's unsure how Crowley exactly feels about her and Horn, though he did warn them to be careful with the cursed weapons as wounds do not heal. He attacked her with a cursed sword to test its ability, shocking her. Faithful to lord Crowley, both she and Horn seem to have a desire for his blood.

Mikaela Hyakuya
Crowley knows of Mikaela and his position and story. He attacks Mikaela and Yūichirō's group in a local fishing village to hold them up until Ferid arrives.

René Simm
Currently a city guard working with Mikaela Hyakuya and Lacus Welt. Ferid gives orders to him on the Shinjuku battlefield.

Horn Skuld
One of Crowley's servants and the one he most often converses with strategically. Which might be because she is the mature and serious of the two. She can usually be found with Crowley along with Chess. Both she and Chess seem to have a desire for his blood. It's unsure how Crowley exactly feels about her and Chess, though he did warn them to be careful with the cursed weapons.

Krul Tepes
Crowley seems wary of her power and considered her a possible candidate to be leaking information to the humans. He acted as a distraction for Ferid to catch her off guard and defeat her, though he seemed to have some doubts about the whole plan.

Lacus Welt
No seen interaction

Shinoa Hīragi
Crowley fights her squad when they enter Shinjuku. He pinned her down and drinks some of her blood.

Yūichirō Hyakuya
Crowley fought Shinoa's squad when they arrived in Shinjuku, and Yūichirō managed to cut off Crowley's arm. He considers Yūichirō to be quite strong for a human. Crowley takes interest in fighting the boy again for another time after Yūichirō displayed his powers after taking more than one pill and thus making his demon side come out, Crowley was clearly excited. Apologizing softly to Ferid that next time, he might "just drink this one dry." He later attacks Yūichirō and the group at a little fishing village in order to stall them.

Guren Ichinose
The leader of the human resistance in Shinjuku and the one in command of the attack against the vampires in Nagoya. Inititally, Guren wanted to avoid targetting Crowley, but added him after finding out the vampire killed an amount of 10/30 soldiers and was holding the remaining 20 captive at his stronghold. They face off with Shinya aiding Guren but the two of them are quickly outpowered. Crowley, having decided beforehand to capture one of the commanders for information to present to Ferid, allows Shinya and the other soldiers to retreat while he takes only Guren as captive. He is surprised to hear Guren is a namanari, not thinking a human like him could have been pulling the strings at all.

Shihō Kimizuki
Crowley shortly encounters Kimizuki during the battle in Shinjuku. Horn drinks his blood when they are defeated. Kimizuki has dubbed Crowley the "red haired monster'

Yoichi Saotome
Guren launched an attack on Nagoya, and when his forces reached the city hall, Yoichi was tasked with sniping Crowley. As soon as Yoichi fired the Gekkōin at him, Crowley catches it's manifestation and flings it aside. Yoichi recognizes Crowley as the vampire noble his squad rammed a jeep into on their way from Harajuku to Shinjuku during the previous vampire attack. Later he once again is the one to recognize Crowley when they near their hiding place at a local fishing village, warning the others.
