When I Arrived in the Pirate World, I Had the Kamui Sharingan.

Luma was originally an orphaned high school student who loved watching One Piece. He followed the latest episode of One Piece as usual. When he saw Ace being killed by Akainu, he was filled with sorrow and hatred. "Damn red*, if I were here, I would definitely kick your head like a ball." "As you wish." A voice appeared in his mind, and he fell asleep on the way. When he woke up, he had arrived in the pirate world. This novel and its characters are purely fictitious.
