Mahiro's New Friend Mihari catches Mahiro mimicking an anime magical girl character before departing for campus, leaving him to laze around until morning. Mahiro loses in a video game match against Mihari and thus shops for groceries, where he befriends Momiji, Kaede's tomboyish middle school sister. Days after, Mahiro swiftly tidies up his room when he sees the two sisters come over; however, he accidentally knocks over his hentai manga collection in front of Momiji.
