It's Sachi's birthday and the school pulls out a big party at the church for her. Kanako is very excited and starts looking at an album with many pictures of Sachi, which is soon confiscated by Mariya. At the party, Kanako has the intention of giving her present to Sachi (an erotic lingerie set) but gets also confiscated by Mariya. After Kanako runs away from the party, Mariya gives to Sachi Kanako's album, saying it was Kanako's present but she forgot it at her room. As a punishment for her nasty attitude, Kanako doesn't have the right to talk during the next episode.

Miki, Kanako's little sister, visits Ame no Kisaki. She met Mariya when she was in elementary school, and has been in love with her since then. She wants to date Mariya when she enters high school, but Kanako tells her she's a boy. Despite this, Miki promises to enter Ame no Kisaki when she's older and to date Mariya.
