As requested by Kenichi, Thor has chosen to leave Ragnarok but he has to be punished for it by the other members. Kisara a.k.a Valkyrie begins to worry the other members so Freya (3rd Fist) is ordered to keep an eye on her. On their way home, Kenichi and Miu run into Kisara who is surprisingly doing something good by taking care of an abandoned kitten but Freya’s girls soon find out about this.

There has been some turmoil between the ranks of Ragnarok’s 8 Fist. Meanwhile Kenichi is still thinking of what will make a fitting deathblow when Nijima informs him of Thor’s (7th Fist), from Ragnarok, lair. This will be the first time that Kenichi chooses to attack head on, even if it’s for Nijima’s benefit.

Kenichi is thinking of coming up an ultimate attack (deathblow) but he’s interrupted by Renka who has discovered where he’s been training. Renka’s arrival begins to cause some friction between Kenichi and Miu’s relationship and eventually becomes a love triangle.

Hermit betrays Ragnarok, by going up against Loki to save Honoka and just when him, Kenichi and Loki were about to get into a fight Odin (1st Fist) comes to end it. But it is not over, because Hermit still wants to finish his fight with Kenichi. With both sustaining terrible injuries, how will this fight end?

After passing many obstacles, Miu, Nijima, Takeda and Ukita arrive on the scene however it is too late. Kenichi’s intense fight with Hermit was cut short, by Loki, who is threatening to harm Honoka. It seems as though Kenichi is willing to do anything to allow his sister to come out of this unharmed.

Honoka has been kidnapped by Loki, so Kenichi is forced into a fight with Hermit, in order to save his sister. Both of their extra training has proven evident, with no determined outcome of this fight. Hermit reveals his tragic past.

Just like always, Kenichi is undergoing to tough training so he can learn a new technique but the training gets to tough and he runs away. Honoka continues to visit Hermit but he soon finds out that she is related to Kenichi. Loki’s plan comes into affect, as he kidnaps Honoka to lure Kenichi.

Later Hermit returns after disappearing for some time and he’s out for Kenichi’s blood. The next day Kenichi and his sister Honoka go out shopping, when they get separated and she runs into Hermit.

While Miu is chasing Loki and is gang, Kenichi continues his intense fight with Siegfried. However no matter what he does Siegfried wouldn’t go down. Is he really immortal? Kenichi will now have to use all that he has learnt to defeat him.

Nijima has been gathering information on Ragnarok, on one member in particular, nonetheless Kenichi quickly dismisses him. While Nijima is out trying to get more info, Ragnarok’s Loki (4th Fist) and Siegfried (5th Fist) captures him. Even though he is reluctant at first, Kenichi ends up going to Nijima’s rescue with Miu.
