越小路 博嗣

He is a relative of Ririka and of Kisaya who is also his childhood friend.

He is very arrogant and manipulative. He doesn't really like Kisaya and only sees his own profit in getting married. He doesn't like Akihito, who's blocking him in his projects and he does not hesitate to use Ririka, forcing her to go and seduce Akihito in the middle of the night, on pain of closing her father's business./
