Sakura, Dokuro and Shizuki are on a school trip where they are asked to draw the scenery, but not without Dokuro harassing him most of the time.

After Dokuro and Zakuro are scared of a "monster" they read about in a myth book, they then want (and force) Sakura to join them in the bath.

Sabato's mother informs everyone that Sabato has to return to the future, but Sakura tries to stop her from leaving, thus everyone ends up in a prison cell. Many attempts to escape go very wrong.
