This 90 min special re-caps the events of the first season.

Originally released as an OAD sold with the Limited Edition of Volume 5 of the Kodomo no Jikan manga to promote the second eason.

Kuro wants to become friends with Shirai, because she admires her and feels they have something in common (i.e. hating Aoki). As a sign of friendship Kuro gives a white hair pin to Shirai and wears a black version herself. One day, Shirai inadvertently hurts Kuro's feelings by dismissing her infatuation for Rin as abnormal. After realizing what she has done, Shirai eventually decides to wear the white hair pin in front of Kuro, making her very happy. Shirai ponders what her life would be like if she had a friend like Kuro in her youth.

Daisuke, Kyoko, Rin, Kuro and Mimi travel to Daisuke's hometown where they meet his family, including his younger sister, Chika. As the girls go to the beach, Rin recalls the times she went to the beach with Aki and Reiji. Later that night, Rin tries to make a move on Daisuke as he sleeps, but backs off when she believes him to be 'a bit too big' for her. Meanwhile, Kyoko, who got very drunk, mistakes Chika for Daisuke and kisses her, though forgets about it the next morning. The next day, the girls help with preparations for Obon, giving Rin fond memories of her mother, so Daisuke lets her hug her during the night. They return home the next day, with Rin leaving behind a photo of them to sit next to a picture of Daisuke when he was younger.
