While preparing for the school festival, Tetsuro's uniform and glasses are destroyed in a painting accident, so Yayoi dresses him up in a girl's uniform. Miya is taken by this fresh-faced newcomer, adopting "Tetsuko Nakata" as her younger sister, and insists that they exchange ribbons. The members of Koi Koi 7 convince Tetsuro to return the ribbon, which he does reluctantly, knowing Miya will be crushed -- and she is, attacking yet again in a giant robot. Celonius 28 has by this time infiltrated the school, and posing as a student, saves Tetsuro from Miya, kissing him before disappearing once again with Kano hot on her tail.
