History's strongest deciple kenichi [TV]
The story focuses on Kenichi Shirahama, an average 17-year-old high school student who has been picked on his whole life. However, on his first day of class, he meets and befriends the mysterious transfer student, Miu F?rinji. Driven by his desire to become stronger, he follows her to Ry?zanpaku, a dojo housing several masters of diverse martial arts, led by her grandfather Hayato F?rinji, who is known as the strongest man on Earth. After learning basics from Miu, Kenichi is able to beat a high-ranking member of the school’s karate club, and becomes a target for all the delinquents in the school. While initially training to get stronger and protect himself, Kenichi eventually becomes a full-fledged disciple of Ry?zanpaku, working hard to fulfill his oath to protect the ones in need, especially Miu, with whom he falls in love. Subsequently, Kenichi’s daily routine is divided between hellish training under the six masters of Ry?zanpaku, and his fights against the members of Ragnarok, a gang that views him as either a possible ally or an impending threat to their plans.
After Ragnarok is disbanded, Kenichi faces a new enemy called Yomi, a group of disciples who are each personally trained by a master of an even bigger organization rivaling Ry?zanpaku, Yami. While the masters of Ry?zanpaku and their allies follow the principle of always sparing their opponents’ lives (Katsujin-ken), the members of Yami believe that defeating an opponent is valid by any means including murder (Satsujin-ken). Caught in the struggle between the two factions, Kenichi, Miu and their ever growing team of allies join forces to fight the members of Yomi, while his masters confront the members of Yami in a battle to decide the future of the martial arts’ world.
