Makoto, Shin's childhood friend, came to the Kouda house. Makoto said she had come to see Kujima, but contrary to her expectations, Kujima spoke in a loud, human language, making her doubt if he was really a bird. Meanwhile, Kujima also started saying things in Russian that sounded like he was picking a fight. Shin stepped in to mediate and tried to get the two to shake hands and make up.

A kotatsu (heated table) was set up in the Kouda family's living room. Kujima, completely captivated by it, spent most of his days under the kotatsu and ended up getting quite plump. Meanwhile, Arata, who had been playing around instead of studying since Kujima arrived, finally got his comeuppance on his final exams, scoring only 38 points. He decided to invite Makoto over for a study session.
