History's Strongest Disciple Kenichi Wiki

The Betrayal Arc is the eighth arc in the History's Strongest Disciple manga series

Story Outline[]

The arc begins at the Ragnarok hideout, with Loki telling Valkyrie, Freya, Thor, and Berserker that he could’ve defeated Kenichi and Hermit if Odin hadn’t stopped him. But the real problem is that a new gang called Yomi has been running amok on their turf. Loki also told him that Odin was the only one that trained under Kensei in secret while the others never even met him. Thor ignored him, since he didn’t care about not having a master as long as he could spread his Combat Sumo all around the world. Freya was about to fight Thor if Valkyrie hadn’t reminded them that private fights between fists are forbidden. Before leaving, he secretly told Number 20 that he planted the seeds of his plan into action. At school, Kenichi was still thinking about what he finishing move was, but in battle he always forgets. Nijima told him that he used his finishing move against a fake Loki at the cafe they were at and named it Strongest Combo. Nijima told Kenichi about a pit club being run by Ragnarok’s seventh fist, Thor. Kenichi didn’t want to do it, but Nijima told him that if he doesn’t attack first then an event like Honoka’s kidnapping would happen again. Outside the Pit Club, Nijima devises a plan to have Kenichi fight Thor without having to fight anyone else first. Nijima had Takeda and Ukita stay outside to prevent them for being noticed, but they were noticed by the Shinpaku Alliance that was supposed to be left outside. Nijima used his brainwashing to have Thor fight Kenichi one-on-one. Kenichi wanted to make a bet first which was that if Kenichi wins then Thor must leave Ragnarok, but if Kenichi loses then Kenichi will do anything Thor wants. Thor remembered that Siegfried left Ragnarok to find himself. The match started in the ring before Thor told Kenichi that he must become Thor’s Sumo apprentice if Kenichi loses. Thor landed some powerful hits on Kenichi, but didn’t defeat him. Takeda saw that Thor has the advantage in the ring, since you can move a lot in a small ring. Kenichi used his Strongest Combo on Thor although the throw was difficult due to Thor’s weight. Eventually, Kenichi shifted Thor’s center of gravity and tossed him up and out of the ring making Kenichi the winner. Thor honored the deal and said he would quit Sumo, but Kenichi told him it was a bet to leave Ragnarok and he should keep improving his Combat Sumo. Before leaving, Nijima told Thor that Kenichi wasn’t a subordinate, he was his friend. Thor remembered his friendship with Siegfried and knew that's why he left. The Shinpaku Alliance carried Kenichi home for his victory against Thor.

Kenichi's Overconfidence[]

Kenichi was being overconfidence when Nijima told Kenichi about about his and defeating over half of Ragnarok. This overconfidence had Kenichi slack off on his training though.
