This is a single song wrapped in animation so quietly delightful it doesn't announce itself. Kyouko Takami's voice carries the whole thing, asking a simple question with the kind of gentle persistence that makes you smile without knowing why. A kid's program song that respects the intelligence of the people watching it.

A single music video made for the song Ninja wa Doko ja, performed by Kyouko Takami. The piece was featured on Minna no Uta, a program broadcast by NHK.
