One Punch to Take Down the Pirates

He transmigrates into the world of One Piece and awakens the Taijutsu inheritance System. From the start, he unlocks Might Guy's inheritance panel.

Saitama. Goku from Dragon Ball.

As one overpowered Taijutsu panel after another from the Myriad Worlds is fused into him, a terrifying Taijutsu monster is born in the world of One Piece.

Hand-to-hand combat, every punch landing solidly: that's a man's romance.

There's nothing a single punch can't solve. And if there is, two punches will do it.

Kaido: "My physique can't compare to his. He's the real monster, the strongest on land, sea, and air."

Garp: "My Taijutsu can't compare to his."

Whitebeard: "He's the real World's Strongest Man."
