Ring Out! The Flute of Shinbu

Synopsis

To obtain the Flute of Shinbu — the item that restores the First Layer — Wataru and Himiko take on a series of riddles. Himiko, racking up correct answers one after another with offbeat logic, is clearly no ordinary girl. She also shines with her "Ninjutsu: Pettan Shuriken." Here it's revealed that when the First Layer is restored, the bad people return to being good as well.
