A bully steals a paper crane and gets pulled into actual starlight. The dream doesn't matter. What matters is that when he wakes up, he gives it back. A single OVA that understands childhood better than shows ten times its length: that moment where wonder stops being about you and starts being about doing right by someone else.

A bully named Takeshi swipes a delicate paper crane from a classmate, only to discover it's something far more extraordinary: a spaceship that can talk. The crane whisks Takeshi and his friends away from the ordinary world into an amusement park out among the stars. When a girl in the group drops through a hole into a place called Space Hell, the children have to pull together to save her. Afterward, Takeshi wakes and is left unsure whether any of it really happened. This single-episode OVA is a gentle sci-fi adventure built around childhood imagination and cooperation.
