S1, E2: Mikoto invites Kazari and Ruiko over to her dorm room to hang out, ruining Kuroko's plans of celebrating her one month anniversary since becoming Mikoto's roommate. Upon learning that Kuroko had ordered aphrodisiacs for the occasion, Mikoto ends up fighting her in the hallway, only for both of them to be caught using their power by the fearsome dorm supervisor. As punishment, both of them are sent to clean the school pool, where Mikoto is introduced to Kuroko's classmates, Kinuho Wannai and Maaya Awatsuki. As Kinuho offers to help Mikoto clean the pool with her aquakinetic powers as thanks for rescuing her from some thugs a while back, Kuroko gets jealous of how well Mikoto is getting along with others, believing that Mikoto has no use for her. To cheer her up, Mikoto gives Kuroko a present celebrating a slightly different anniversary, being the day when they became friends. However, whilst toasting, Kuroko accidentally drinks the aphrodisiac she had intended to give to Mikoto, becoming so overcome with lust that she steals Mikoto's underwear while she is still wearing them, prompting an electrical punishment.
