Yeah, Kenichi’s a total wimp. He’s always getting picked on and doesn’t have a lot of friends to stick up for him. The guy needs motivation if he hopes to graduate in one piece.
Well, Miu’s the perfect motivation. She’s hot, she accepts him, and she just so happens to live at a dojo with six martial arts masters. You could say fate has led Kenichi to their door, or you could say he was just following the hottie. Either way, he’s about to get whipped into serious shape. If he can survive some hard-core training, he might survive another day at school. He might even score with Miu. Yeah, you could call Kenichi a wimp. But let’s go with underdog instead.
“Weak Legs” Kenichi Shirahama would rather spend his time reading self improvement books than fighting. However, when he finally works up the courage to become strong and join his school’s karate club, he is coerced into fighting a bullying upperclassman who is intent on getting him kicked out of the club. He is about to give it all up until he falls for his mysterious new classmate, Miu Furinji. In order to face this challenge, he undergoes rigorous training at the dojo she lives at, Ryouzanpaku. Some initial training by the masters there allow him to defeat his upperclassman, however his fighting prowess brings him to the attention of the powerful gang of delinquents, Ragnarok. Wishing to protect the things he loves and determined to have the strength to face the increasing adversity, he must learn various martial arts from the dojo’s resident masters, taking Karate, Muay Thai, Ju Jitsu and Chinese Martial Arts and combining them to create his own fighting style!
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?
