Limited edition manga volumes came with a string of OVA episodes. The first episode, "Anata ga Watashi ni Kureta Mono" or "What You Gave Me," follows the shopping adventures of Kokonoe, Usa, and Kagami as they hunt for the perfect present for Sensei. When they don't find what they're looking for, Kokonoe takes it upon herself to create one. As they spend the night at her house, secrets about their respective love interests come to light: Usa's obsession with Reiji, Kagami's feelings for Kokonoe, and Kokonoe's own love for Sensei. In "Kuro-chan to Shiro-chan" or "Kuro-chan, Shiro-chan," Kuro-chan attempts to befriend Shirai-sensei. Finally, "Kodomo no Natsu Jikan" or "A Child's Summer Time," features the girls, Aoki, and Houin visiting Aoki's family in the countryside.
