Japanese name:

吉田 優山

Yūzan Yoshida is Haru's older brother, whom Haru seems to dislike. Yuzan claims Haru has a brother complex, though this is denied by Haru himself. He came to take Haru back home upon their father's request for Haru to attend a nearer school, where he has more leverage, although Yuuzan does want Haru to continue going to school with Shizuku.
