After Roy traveled to One Piece, he realized that something was wrong in this pirate world!
Devil Fruit is a curse. As long as the person with the fruit's ability does not use the ability, once it is used, if he does not transform into a Kamen Rider to bear it, his body will explode and die immediately!
After saving Luffy from dying and letting him become a Kamen Rider, Roy became the only knight mentor in the sea.
Shanks solemnly entrusted the future of Straw Hat and Luffy to him.
When the world's government and navy run rampant with mass-produced drives,
When the Knights of the Beasts of the Four Emperors roared into the new world,
Roy adjusted his glasses and took out his Vientiane Driver.
"Sakaski, your magma drive is overheating."
"Kaido, the version of your fish fruit ability should be updated."
It wasn't until the end, the final battle, that Im was horrified to discover that the drive technology they monopolized was all pirated copies full of loopholes in front of Roy!
