3

Whilst sweeping up outside, Hiroyuki bumps into third year Serika Kurusugawa, the sole member of the school’s Occult Research Society. Serika gets Hiroyuki to help her gather ingredients for a magic potion, and subsequently lends him a book on black magic and invites him to participate in one of her ceremonies. However, Hiroyuki forgets and goes to a games arcade with Shiho, leaving Serika waiting alone after school until Akari notices her and goes to find Hiroyuki. (Source: Wikipedia)
