Genjirou Shiragami

Youko's father, a pure-blood vampire, possesses a physique several times that of an ordinary human. He is a novelist and writes a fiction novel titled "Vampire Breeding Diary". He writes on standard manuscript paper, which seems quite cramped for him.

He is very strict with his daughter, but in reality, he dotes on her deeply. On the other hand, he is completely submissive to his wife, Kiriko.

He met Kiriko during high school and fell in love; like Youko, they lived hiding their vampire secrets, but failed.

When Asahi and others advanced to their third year, he entered the school as Midorisaka Yumi (mentioned above).

He is 452 centimeters tall and weighs 825 kilograms. Born on May 5th, blood type B. He likes alcohol and his daughter. He dislikes crosses, garlic, and cockroaches. His special skill is building card towers. His hobbies include gaming, writing novels, and fishing.
