Synopsis

Continues the story of Kinnikuman: Perfect Origin Arc

After a fierce series of battles among various Choujin factions—superpowered beings from across the cosmos—the former enemies of the victorious Seigi Choujin manage to arrange a fragile truce. However, this peace is quickly shattered when the Perfect Large Numbers, a group of seven Perfect Choujin led by Strong the Budo, invade Japan. They overwhelm several Seigi Choujin, reigniting the conflict. Determined to defend the peace at any cost, Terryman, the new leader of the Seigi Choujin, confronts the Perfect Large Numbers in a struggle for dominance. Despite the overwhelming odds, Terryman trusts that Suguru Kinnikuman, the strongest Seigi Choujin, will see that justice prevails.

In this installment

In the continuation of the Kinnikuman series, Kinnikuman II Sei introduces Mantarou Kinniku, the 59th prince of Planet Kinniku and son of the legendary wrestler King Suguru. Known for his laziness, cowardice, and immaturity, Mantarou appears far from his heroic father's legacy. When the menacing dMP organization endangers Earth, a fighter with Kinnikuman’s caliber is needed to thwart their plans. With King Suguru missing, Mantarou is chosen as his successor. Initially resistant to the idea of battling supervillains, Mantarou runs away from his responsibilities and lands on Earth. There, he encounters Meat, his father's former coach. Recognizing potential in Mantarou despite his shortcomings, Meat believes he can transform the prince into the hero Earth needs. This marks the start of Mantarou's quest for self-improvement and saving the planet.
