Sourcebook
Intro
In vampire society, there exist five prestigious lineages known as the Five Great Families. One of them is the Tatsumi family.
The heir, Seiji Tatsumi, was a perfect existence—flawless in grades, appearance, and conduct as a successor.
Except for one major problem.
Despite being eighteen, he has no fiancée.
This was an exceptional case for an heir of the Five Great Families.
Not only his father, the current head, but also his Three Guards—Nachi Tatsumori, Kaname Chimiya, and Kei Janome—were troubled by this issue.
Furthermore, Seiji, the person in question, simply brushed it off, saying he "saw no necessity" for it.
