After becoming Choujin Olympic Champion, Kinnikuman is sent on a 'World Tour', as part of his duties as Champion. While the rest of the Chojin go their separate ways, Kinnikuman makes a very brief stop at Planet Kinniku. It is there he learns that if he deviates from his schedule, he will lose his title.
Landing in Hawaii, Kinnikuman is told that his opponent for the Hawaiian Championship Belt is Jesse Maivia. But before that, he has to fight Jesse's servant, Prince Kamehame from Planet Coconuts. Kamehame used to be the Hawaiian Championship, winning 999 times. Seeing how old Kamehame is, Kinnikuman accepts.
- Kinnikuman vs. Prince Kamehame - Despite Kinnikuman's confidence, Kamehame traps him in pin within seven seconds.
After the match, following several failed attempts to challenge Jesse directly, Kamehame offers to teach Kinnikuman his 48 Finishing Techniques. With new strength and new confidence from the training, Kinnikuman challenges Jesse.
- Kinnikuman vs. Jesse Maivia - In a No-Ropes-Deathmatch, Kinnikuman finds that every move he tries, including the Mexican Clutch used to defeat Robin Mask, can be reversed by Jesse, the Master of the Move Reversion. In despair, Kinnikuman loses faith and asks Jesse to finish him. When Jesse hesitates, Kin taunts him, wondering aloud if all Jesse can do is reverse someone else's moves, having no attack power of his own. In rage, Jesse attacks Kin, but soon has his own move turned on him. Kin finishes Jesse with Fu Rin Kazaan, one of the 48 Finishing Moves, winning the match.
Following the match, Kinnikuman gives the Hawaiian Belt to Kamehame. However, he also gives the prize money for the match as well, meaning he and Meat now have to swim to North America, having no way of paying for their flight...
Choujin League Dispute
In America, Kinnikuman learns from the World Supermen Association head, Dorlo Phlears, that during the Chojin Olympics, the World Supermen Council and the World Supermen Federation have taken control of the eastern and western halves of the American Chojin world. To retake America for the WSA, Kinnikuman is disguised with shoe polish and a cowboy outfit as the 'Chanelman' and attacks the district champions of the WSC, starting with the WSC champion, Beauty Rhodes.

As Chanelman continues to defeat the WSC Chojin, the Council claim that it's the work of the Federation. At the WSF's headquarters in Las Vegas, Chanelman watches as the WSC and WSF begin to fight. However, the confrontation was just a ruse to draw Chanelman out, and accuse him of being Kinnikuman. Kin quickly makes up a story about being from Africa and wanting to join the WSF. Skull Bozu, the WSF champion, apparently believes this and invites 'Chanelman' into the Federation. Furious at this betrayal, the WSC head Eddith Harrison orders Rhodes to attack.
- Skull Bozu vs Beauty Rhodes - Skull easily rips off Rhodes' face, forcing the WSC to retreat.

Not wanting to lose the same way he did with Kinnikuman, Robin breaks Piper in half.
Kinnikuman is horrified at this, but his sweat has caused his make-up to dissolve, ruining his Chanelman disguise. Robin, seeing his old rival, quickly challenges Kin to a rematch for his title. The match is to take place in a ring above the Grand Canyon viewed by spectators in flying cruise ship, but the WSF have hired Kinkotsuman and Iwao to help out...
- Kinnikuman vs. Robin Mask - Robin starts off with a flying kick, and then a series of punches, forcing Kinnikuman into the ropes. One rope breaks, and Kin escapes by telling Robin that his wife Alisa is in the stands. This doesn't work for long, and soon Robin is punching away again. However, he misses and almost falls out off the ring, grabbing a rope for salvation. Kind-hearted as he is, Kin can't let Robin fall like that, and helps him up. However, Robin isn't moved, and puts Kin into the Tower Bridge. Kin manages to escape by inverting his position, putting his chest on the Robin's shoulders, and soon the two are brawling again. Annoyed at this, Skull Bozu orders Iwao to crash a plane into the ring, apparently killing both Chojin. Robin is declared the winner by the WSF judges, but since he is dead, Skull Bozu takes the title by default. But as it turns out, Kin and Robin are alive, but Robin is trapped under the plane, having knocked Kin out of the way in time. It is then that Robin reveals what happened after the Chojin Olympics. He and Alisa moved to Africa where Robin became an animal ranger.
