Shin Dokonjou Gaeru

Middle schooler Hiroshi is as hot-blooded as ever, but his strangest companion is still Pyonkichi, the stubborn frog flattened onto the front of his shirt after an unlucky fall. Pyonkichi can talk, argue, eat, and interfere in Hiroshi's life with enough force of personality to make being a living shirt seem almost ordinary.

Between clashes with friends, teachers, neighborhood troublemakers, and Hiroshi's long-suffering mother, the inseparable pair stumble from one ridiculous problem to another. No matter how fiercely Hiroshi and Pyonkichi quarrel, their unusual friendship keeps pulling them back together for another loud and chaotic day.
