History's Strongest Disciple Kenichi
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?
