The Overpowered Cheat Starts an Adventure in One Piece

Looks very confused

The plot is too fast

It's still three stars. It adds a lot of private settings and it looks pretty good. Without adding any private settings, it feels like it can reach 8.0. The most important thing is to add a forcibly weakened black coffin.

There is no need to add another weakness to yourself by eating Devil Fruit, just develop more of the Five Spirit Kings.
