Dokonjou Gaeru

Middle schooler Hiroshi trips during a fight with his rival Gorillaimo and lands on a frog. Instead of dying, the frog becomes a living print across the front of Hiroshi's shirt, introduces himself as Pyonkichi, and immediately begins interfering in his owner's life.

Pyonkichi speaks, argues, eats, and displays strength far beyond an ordinary frog, making him both Hiroshi's closest companion and greatest source of embarrassment. School rivalries, family trouble, and neighborhood romance become louder whenever the stubborn pair disagree.
