Kinnikuman II Sei: Ultimate Muscle

The legendary Kinnikuman, once a goofy but powerful hero, has long since retired from the wrestling ring. Now, his son, Mantaro, is tasked with upholding the family name and defending Earth from a new wave of monstrous Choujin. But Mantaro is a far cry from his father's stoic strength, preferring to chase girls and avoid training whenever possible. His journey to become a true Ultimate Muscle is paved with hilarious blunders, unexpected friendships, and a whole lot of spectacular, over-the-top wrestling action. Join Mantaro and his colorful cast of allies and rivals as they grapple their way through outlandish tournaments and intergalactic threats. This sci-fi action-comedy delivers a perfect blend of high-flying martial arts, slapstick humor, and genuine heart, proving that even the most reluctant hero can rise to the occasion when the fate of the world (and his own reputation) is on the line.
