Jubei-chan

Jiyu leaves her Lovely Eye Patch at home because she doesn't think she will need it at school. Seeing this, Koinosuke heads to her room to get the Lovely Eye Patch so that he can give it to her. However, her father, Sai, reminds him that he should not go into a girl's room.

At school, Jiyu has a new teacher named Hariu Tessai, who quickly develops a crush on her. After school, Hariu challenges Jiyu to a duel. Jiyu gives Koinosuke permission to go into her room to get the Lovely Eye Patch. Koinosuke quickly retrieves it and gives it to her. Jiyu transforms into Jubei II and defeats Hariu.
