After losing a fight to Nenji, Jinpachi must cut his hair to match his rival's style. When Nanaka's glasses break, she mistakes Jinpachi for Nenji and asks for his help. Jinpachi agrees to accompany her on errands and activities that resemble a date with a child. Jinpachi's sister, Satsuki Arashiyama, is displeased with the situation and attempts to attack Nanaka, but Nanaka inadvertently dodges the blows. Later, when Nanaka is with Nenji, Satsuki tries to attack them again. However, Nanaka trips and accidentally saves Satsuki from a falling wooden sword shard. Impressed by this turn of events, Satsuki asks Nanaka to be her big sister.
