Synopsis

While the world tunes in to watch a major choujin rugby match, Hydra King—calling himself the Underground Space Emperor—has his Underground Space Supermen kidnap Robin Mask. The plan is simple: use Robin Mask as bait to draw out the Seigi Choujins, then exploit the Robin Memo, a document listing all their weaknesses, to take them down. Kinnikuman and the other Seigi Choujins catch the broadcast and realize what's happening. They team up and head straight for Planet Hydra to rescue Robin Mask and stop Hydra King's scheme.
