Synopsis
Kenichi Shirahama, a high school student constantly bullied and seeking self-improvement, meets Miu Furinji, a skilled martial artist.
After a challenge forces him to either fight or quit his karate club, Kenichi seeks Miu's help to become stronger.
Miu directs him to Ryouzanpaku, a dojo filled with eccentric martial arts masters who promise to train him.
Kenichi begins his rigorous training, facing the challenges of Ryouzanpaku while also dealing with a dangerous criminal martial arts gang, Ragnarok, threatening those he cares about.
He embarks on a journey to become a stronger fighter and protect the weak, but surviving his training will be his first challenge.
