Ferid Bathory/Relationships

Chess Belle

Crowley Eusford
A thirteenth progenitor and member of Ferid's faction. He resides in Nagoya. They appear to be friends. Crowley follows Ferid because he claims Ferid always makes interesting things happen. He joins Ferid on the battlefield in Shinjuku, and later meets him again in Nagoya after Guren had been captured. Things got tense when Crowley accused Ferid of revealing his whereabouts to the humans, though the silver-tongued noble explained he did that so no one would suspect him of leaking secrets to the humans. He is also most likely the one who turned Crowley into a vampire.

Horn Skuld
One of Crowley's aides and a seventeenth progenitor. She resides in Nagoya with Crowley. She dislikes Ferid and considers him to be sneaky. She goes with Chess to fetch Crowley in Shinjuku before joining Ferid on the battlefield.

Krul Tepes
The vampire queen of Japan and a third progenitor. She is forever stuck in the form of a twelve-year-old girl. Ferid enjoys her angry expressions, and he loves her power as well. Naturally, she hates his guts. She turns Mikaela Hyakuya into a vampire. Ferid is using blackmail against her to prevent her from killing him, but she sincerely wants him dead.

Lacus Welt

Lest Karr
A third progenitor who is contesting Krul Tepes for rule over Japan. He recently exterminated a group of spellcasters in Europe who were experimenting on the Seraph of the End. Although he is 200 years younger than Krul, he claims to be stronger than her.

Lucal Wesker
A member of Lest Karr's faction. He considers Ferid to be unpredictable. He is killed by the Moon Demon Company when they attack Nagoya.

Mikaela Hyakuya
A survivor of the Hyakuya orphanage and one of the seraph of the end. Krul takes him into Sanguinem in 2012 to raise as livestock. At some point, Mika approaches Ferid. Ferid gives him money and good food as payment for biting Mika and drinking his blood directly. However, Mika's goal is actually to steal a map and escape Sanguinem. Ferid feigns ignorance and waits for Mika at the exit. When the orphans try to escape, he slaughters all of them except for Yuichiro and Mika. Mika charges at Ferid to give Yu a chance to escape, and Ferid fatally wounds him. Afterward, Krul Tepes turns him into a vampire. Since she lets Mika drink her blood instead of human blood, Mika continues to age. Ferid is concerned that Mika may grow beyond the age he considers to be most beautiful.Ferid teaches Mika how greedy and wicked humans are, and Mika even witnesses the humans turn Yu into a mindless monster on the battlefield. Ferid often prefers to be close to Mika and establishes physical contact with him at every opportunity, but Mika usually tells him to shut up or moves away from him.

After becoming a vampire, Mika lives only to rescue Yu. He is known as Krul's favorite pet. Although Krul claims to be his own, Ferid considers Mika to be his favorite servant. Mika currently works as a city guard with Lacus Welt and René Simm.

After Yu arrives, Ferid defeats him again and has him by the neck until Major General Shinya Hiragi attempts to snipe him. Crowley captures him in Nagoya, planning to let Ferid deal with him.
