Middle school student Miharu, a quiet loner whose life's plans extend to the inevitable inheritance of his parents' Okonomiyaki shop, carefully avoids becoming involved in anything that would require him to care about anyone (or anything), or worse, require anyone to care about him. Unfortunately, his dreams of perfect apathy are shattered when he discovers that he holds The Secret Art shinra banshu--the power to control everything in creation--inside his own body.
