Reincarnation Game: Starting from Naruto

Makoto Nishikado was just another transmigrator dropped into a chaotic crossover world. At Shuchiin Academy, surrounded by elites who could bend reality with their family influence, he was reminded of a brutal truth. Where you’re born decides everything. Then the Reincarnation Game descended. Survive… or die. Each instance was a different world. Clear it, or be erased. And the real twist? Anything you gained inside those worlds… you could bring back. Naruto~ While other players were still fumbling through ninja school, learning the Three Basic Jutsu, Makoto had already slipped into the Uchiha Clan Masscare. When the blood settled, he walked away with the Mangekyou Sharingan. One Piece~ Others debated whether to join the Marines or the World Government. Makoto? He teamed up with Blackbeard. Hunting down powerful Devil Fruits... not for himself, but for the women waiting back home. Dragon Ball~ While everyone else argued over which master to follow… He stole a spaceship. Headed straight for Namek. And used the Dragon Balls to rewrite himself into a Saiyan. — Description from novelcodex.org
