Shirahama "weak legs" Kenichi is a typical high school student with typical problems: he's frequently bullied and tends to run away in the face of his enemies. Things change when Kenichi meets Furinji Miu, whose grandfather runs a dojo; and not knowing what he's getting himself into, he signs up to become a disciple. As Kenichi's life-threatening training continues and he becomes more and more powerful, he inadvertently becomes the target of the deadly gang called Ragnarok. With mental and physical challenges ahead, can Kenichi survive his encounters with Ragnarok, or will the masters of his dojo get to him first?
Both of these series share a love of fighting and use it as the central part of their respective stories. This fighting is given new meanings by its constant changing and the growing of the main characters as they learn to fight better and defeat stronger and stronger enemies.
