Not much is revealed about Yoshihisa during the anime or even about his family life except that he and Hiyori Moritani go back quite a while, she often offering for him to come and visit her dojo. Before meeting Haruka Kotoura, he was like any other teenage boy, going to meals with his friends and hanging around with them. https://kotoura-san.fandom.com/wiki/Category:Characters
