The Demon King's Op-Op Fruit

A little observation, plus a touch of creativity...

The Op-Op Fruit is far more powerful than you think!

What would happen if the characters in One Piece really put their minds to developing their abilities?

Welcome to a technical-minded pirate story with a power system set many levels higher!

Delve into the lore behind One Piece: the origins of the devils, the true nature of Devil Fruits, and the secrets of the Celestial Dragons.

Hopefully these poor characters won't go crazy.
