One Piece: This Barbarian King Is Pretty Fierce

Mu Bai transmigrates into the world of One Piece, binds himself to a League of Legends System, and becomes a blood-soaked Barbarian King.

And so, during the Paramount War, a fully equipped young man appears, having hacked his way from being a little pirate all the way to the Execution Platform!

To Mu Bai's surprise, the System lets him freely switch between heroes.

Yasuo, the Unforgiven; Master Yi, the Wuju Bladesman; Caitlyn, the Sheriff of Piltover; Lux, the Lady of Luminosity; Garen!

Huh! Wait a minute, how come Ultra Rapid Fire is here too!

"Feel the wind!"

Akainu: "That bastard Mu Bai actually blocked my Meteor Volcano!"

Kizaru: "Mu Bai is terrifying. I think I'll just keep sitting this one out!"

Whitebeard: "Mu Bai, I'm going to make you the Pirate King!"

One day, Mu Bai switches into the adorable little girl Annie.

The System glitches, and Mu Bai is instantly dumbfounded. Is it going to make him a female Pirate King?
