Krul Tepes/Relationships

Mikaela Hyakuya
Turned into a vampire in 2016 against his will by Krul Tepes. He ages still because he has yet to drink human blood and is dependent on Krul's blood. Currently a city guard working with Lacus Welt and René Simm. A survivor of the Hyakuya orphanage, who is taken into Sanguinem by Krul Tepes when she has actually been ordered to kill him. One of the "seraph of the end." Ferid fatally wounds him when his orphan family attempts to escape, and Yuichiro Hyakuya escapes by leaving him behind. Krul teaches him how nasty humans are. She gives him the motivation to save Yu from them. Ferid presents Mika as his favorite servant to the Progenitor Council. Krul Tepes's favorite pet. He appears to be the only one besides Krul who knows her true plans.

Seventh Progenitor Ferid Bathory
A meddlesome vampire, who is always smiling. He allows the seraph child Yuichiro Hyakuya to escape in 2016, and he fatally injures Mikaela Hyakuya. It is uncertain if he planned to turn Mika into a vampire or kill him. He claims Yu shot him in the head in order to escape, which Krul believes is a lie. He knows Krul has dabbled in the "seraph of the end," and he is using this information to blackmail her into not killing him. He adores Mika and touches him at every opportunity, and he often acts as if he is Mika's master. He even presents Mika to the Progenitor Council as his favorite servant rather than Krul's. A sadistic pedophile, he also likes the permanently youthful Krul, especially her angry expressions. Krul hates him and wishes she killed him back in 2016.

Third Progenitor Lest Karr
Although he is younger than Krul by 200 years, he claims to be stronger than her. He wants to take her place as the ruler of Japan.
