Ragnarok member Thor plans to develop his Sumo wrestling into a practical martial art. Loki plots against Odin by planning to replace him with Berserker.

Niijima suggests Kenichi go on the offensive by attacking a Ragnarok member. Kenichi asks his masters advice on being the one to instigate violence. The masters are happy Kenichi has matured enough to ask such a question but insist that finding his own answer is an important part of his training. Kenichi decides it is acceptable to attack as long as he fights with honour. Kenichi and Shinpaku Alliance head to an underground fighting arena run by Thor where Kenichi challenges him to a match. If Kenichi wins, Thor must leave Ragnarok, if Thor wins Kenichi must become Thor's disciple and help him make Sumo into a real martial art. They enter a ring that has been dug into the ground so fighters cannot be thrown out, and instead must be beaten unconscious. Due to his thick muscles Kenichi is unable to hurt Thor with his normal attacks and gets hit by him several times. Kenichi uses his death blow on Thor but struggles to throw such a heavy opponent. Somehow Kenichi finds the strength to lift Thor completely off the ground and throw him out of the hole, which counts as Thor leaving the ring and being defeated. As an honourable martial artist Thor admits defeat and swears to leave Ragnarok and give up on his dreams to develop Sumo wrestling, though Kenichi points out he only asked Thor to leave Ragnarok and encourages him to keep following his dream.

They are surprised that Shigure plans on eating with them at the table instead of alone in her room. The Elder is happy Kenichi has such a positive effect on her. Tochūmaru sends Shigure a firework signal warning her Kenichi is in trouble. The vet assures Miu the kitten is merely unconscious so she rushes to help Kenichi.

He also remembers Ryūto bought the cat badge Kenichi ended up trading to Miu and together he and Ryuto watched the 6 year old Miu beat up 3 thugs trying to rob the store, which led to Kenichi and Ryuto making their promise, to train in martial arts until they became as strong as Miu.

Sakaki and Apachai take Honoka to a restaurant where Sakaki knocks out a thug also without touching him, explaining to Honoka that he used his Qi to knock out his opponent with his powerful killing intent, the same move Ryuto used on Kenichi. Despite being injured Kenichi uses his own Qi to stand, shocking Ryuto. Miu explains, as Kenichi is routinely beaten up by masters who are far stronger than Ryuto, he has gained a tremendous level of resistance to physical damage. Despite this Kenichi is unable to get past Ryuto's "Seikuken", the area around his body over which Ryuto has perfect control, allowing for perfect defence and offense everywhere within the reach of his arms and legs, and as Kenichi has no real killing intent he is unable to break the Seikuken, even with his death blow. Ryuto steals his Yin-yang badge and replaces it with his own identical Yin-yang badge he also bought 10 years ago after Kenichi did something he found unforgivable, claiming it to be the badge of a loser. He leaves with Kenichi's badge. Niijima starts a rumour that Tanimoto has joined Shinpaku Alliance, when in reality it was Siegfried, now a member of Shinpaku Alliance, wearing Tanimoto's Hermit clothes. At Ryozanpaku Dojo the masters mercilessly tease Kenichi over his defeat until he regains his fighting spirit. The Elder reassures Kenichi that even though he lost he learned more about himself than he would have done had he won.

The Elder proves adept at catching fish with his bare hands, while Kenichi catches nothing and instead scavenges nuts from the forest. The unseen presence continues to harass Kenichi who goes against the Elders orders and secretly trains at night, which leaves him exhausted and starving. He attempts to steal the Elders food but ends up lost in the forest. At Ryozanpaku Dojo they become worried for Kenichi's safety and threaten to serve Akisame nothing but green bell peppers, which he hates, unless he tells them what the Elder is up to.

Kenichi is found unconscious by Ogata Ishinsai who lives alone in the Dark Valley. Kenichi tells him about his defeat by Odin.

Due to his loss against Odin, Kenichi is dangerously close to losing control, and the Elder is trying to prevent this happening. Akisame explains Ryozanpaku Dojo had a disciple before Kenichi, Ogata Ishinsai, who did lose control and was expelled after he killed another martial artist. Kenichi is attacked by a bear but is saved by Ogata who brutally slaughters it, horrifying Kenichi. Ogata offers to become Kenichi's master and train him to gain the power to kill his opponents.

The Elder is happy Kenichi has learned to control his anger and teaches Kenichi how to use the Seikuken, allowing him to finally catch a fish. Kenichi also manages to defend himself from the Elder, who was actually the one swiping at the back of his head with his super speed. Kenichi's joy at learning Seikuken soon disappears when the Elder announces his real Dark Valley training can now begin.

Kisara disagrees as she chooses to use martial arts to become stronger rather than rely on a weapon to gain strength. Miu keeps the Valkyrie from interfering in their fight.

Odin recalls how, as a child, he realised Kenichi was not as dedicated to learning martial arts as he was and after Kenichi's betrayal bought himself a Yin-yang badge and trained for 10 years to defeat Kenichi and prove he was weak by swapping his badge for Kenichi's. Eventually he witnessed Sage fist mercilessly kill two assassins and became his disciple to attain power. Kenichi allows himself to be struck several times to get in close and use the powerful punch he used to defeat Siegfried, though Odin still manages to block it. Realising that Odin can predict his every move with his Inner Eye Kenichi instead models his movements after all of his masters, completely changing the rhythm of his movements so that even Odin's Inner Eye cannot predict where he will strike. By copying the movements of Apachai, Sakaki, Kensei, and Shigure Kenichi is able to land multiple powerful strikes on Odin. This greatly entertains the watching masters who are proud their disciple has improved to such a degree as to copy their moves. By finally imitating Akisame Kenichi performs a Judo throw but Odin is accidentally wounded when he lands on broken metal. Odin, furious that Kenichi still does not remember how he betrayed him as a child uses an extremely dangerous technique, by combining both the Dou and Sei energies in his body he becomes monstrously powerful.

She defeated the thug but Kenichi was knocked out and Odin took the credit for warning Miu. Feeling guilty Odin fought with Kenichi over the Yin-yang badge, though Kenichi ended up winning he tried to give Odin the badge and said if anyone asked, Odin could claim he won their fight. This drove Odin to train for 10 years, not so he could take the badge, but so he could finally win against Kenichi for real.
