Pirates: It's not a mythical beast, it's a phantom god

Bad news: I traveled through time during the duel.
Good news: This isn’t the Yu-Gi-Oh world, so you don’t have to risk your life playing cards.
The bad news: This is the world of One Piece, and you can't survive without fighting.
Good news: there is a cheat code.
Bad news: The original male body was replaced with a set of teeth!
Good news: The new body is even stronger! Dominant! Stronger!!!
"Immortality! Agelessness! And then... Phantom Power!"
"Kaido, you will be defeated today! The phantom god rotates one million horses——Super conductive wave thunder muzzle!!!"
……
“Hehe~ Hehe~”
"Ossi, Ossi? Wake up. Captain Kaido is calling you."
In the meeting hall of Onigashima, a red-haired girl who was talking in her sleep was gently awakened.
"Ah, ah? What's wrong?" The girl looked up blankly and saw Kaido's big face.
"Wooo-ha-ha-ha~ Ossi, what are you mumbling in your dream?"
"Oh, I think the Governor has a good idea~"
PS: This is a story about a card player who travels through the pirate world and becomes one of the three mythical gods (feminized versions).
