The bell is about to ring on Kenichi's biggest fight yet. In this corner: Takeda, a former pro boxer with a mysterious past. It's going to be a slaughter unless Kenichi can pinpoint the pugilist's weakness.
What makes a pro athlete trade his dreams for a life as a Ragnarok goon? Takeda has no problem sharing the tragic tale - just like he's got no problem pummeling Kenichi in a rooftop brawl.
Following Takeda's failure, Ragnarok goes to Plan B: Kill Kenichi. A brawler named Tsuji is dispatched to deal with the kid once and for all. Little do his commanders know, Tsuji has a Plan C of his own creation.

Ragnarok is preparing for war. The gang of delinquents is stronger than ever, their ranks bolstered by the promotion of a tough girl named Kisara - and she's got Kenichi and Takeda in her sights.
What makes a fighter stand above his foes? Some are blessed with natural skill. Others must depend on perseverance. As Takeda ponders these thoughts, he will face a demon from the past.
Kenichi is rushing to Takeda's aid as the boxer faces off with the Ragnarok squad. He may thrash his way through the foot soldiers, but Kisara waits for her chance to punish Takeda's betrayal.
Niijima has created an army - The Shinpaku Alliance. With Kenichi's brawn and his own brain, Niijima figures their path to legend is certain. Kenichi knows better - and Ragnarok's troubled by the clique, too.
When Niijima and Izumi visit Ryozanpaku, you could cut the tension with a sword. Miu and Izumi trade a few uneasy smiles, but Kenichi might have to intervene before they start trading blows!

Ragnarok captures Niijima and the gang's preparing to ship him far, far away. Miu and Kenichi rush to the rescue - but Siegfried's got plans to make Ryozanpaku's disciple face the music.
Niijima's still in trouble - and so is Kenichi. Siegfried's reputation as an unbeatable opponent appears to be valid, and unless Kenichi can put his training to use like never before, his friend is doomed.
Hermit returns from his self-imposed seclusion, eager to beat Kenichi once and for all. His time away was spent training, but nothing could prepare him for who he must deal with next - Honoka!
Tired of the torturous training, Kenichi runs away from Ryozanpaku - straight into the biggest fight of his life. Honoka's in trouble, and if he wants to save her, Kenichi will have to get through Hermit first!
Kenichi is taking a serious beating when Hermit shares the tragic tale of his childhood. With Honoka in real danger, Kenichi knows the time for words is over - he'll let his fists do the talking.
