A mischievous kid solves impossible problems with logic instead of power, turning every mistake into a lesson nobody saw coming. The show knows Ikkyu's real superpower isn't being smart, it's caring enough to use it for people who have no one else. 296 episodes of a boy outwitting his own teachers to save someone, one riddle at a time, and somehow never running out of new ways to do it.

A precocious young boy named Ikkyu lives at Ankokuji Temple, where he is training to become a monk. He is mischievous and something of a troublemaker, but also remarkably bright, and he keeps coming up with fresh ways to get the better of his exasperated teachers. His clever schemes often end up helping other people along the way. The result is a long-running comedy about a sharp little monk whose quick wit keeps temple life anything but dull.
