Megalo Box

The plot centers on a man (only identified by the ring moniker Junk Dog) who competes in pre-arranged contests in fight clubs that are situated in the Restricted Area. He nearly collides with Yukiko Shirato, the CEO of the corporation Shirato Group, one evening as he is riding his motorcycle in the Administrative Area. Junk Dog gets into a battle with Yri, her bodyguard and Megaloboxing champion. Yukiko breaks up the fight, but Yri goes in search of Junk Dog and finds him in a fight club. After easily defeating the less-experienced fighter, Yri challenges Junk Dog to a rematch in the Megaloboxing competition Megalonia, for which Junk Dog would need to be at the top of the official Megalobox rankings and possess the necessary citizenship ID in order to enter the rankings in the first place. The two are granted three months to reach their objective of climbing to the top of the Megalobox rankings in order to have a shot of competing in Megalonia after Junk Dog's coach Gansaku Nanbu convinces the mafia boss Fujimaki to forge Junk Dog an ID under the name Joe.
