One Piece: The Mixed-Blood Ninja Mingling on the Straw Hat Ship

As a mixed-blood of Uchiha and Senju, Xiyan shone brilliantly during the Second Ninja World War. On the way to execute a mission in the Land of Water, he unexpectedly crossed over to the One Piece world and encountered the sea train heading to Enies Lobby!

On this rapidly traveling train, Xiyan met that boy bearing destiny.

"You're a ninja?"

"Yes."

"Be my crewmate!"

"Sure."

Since he's here, might as well stay. Invited by Luffy, Xiyan chooses to join the Straw Hat Pirates. Afterwards, using his own power, he helps his partners rescue Robin and save the ship spirit · Going Merry!!

......

Marineford War. Possessing the invincible dojutsu 'Takemikazuchi no Mikoto' and 'Kudomio no Mikoto', Xiyan unleashes a massive Susanoo, rampaging through Marine Headquarters and making the Marines feel what true power is. The divine weapons 'Kudashi Spear' and 'Illusion-Reality Devouring Bow' in his hands terrify the Marines!

Sengoku: "Damn it, this guy's just a ninja—why does he possess such overwhelming power?!"

Kizaru: "The newbies these days are so scary~"

Akainu: "Evil pirate brat, I'll handle you personally......"

Xiyan: "Come on, let's fight to our hearts' content!"

......

New World. Facing peak powerhouses, Xiyan decisively activates the ultimate Uchiha-Senju combination technique.

Sage Art · True Several Thousand Hands!

Third Power · Susanoo!

Susanoo-clad Giant Buddha!

"If you survive my attack, then you can try my Six Paths powers too!"

Xiyan, with his Rinnegan activated, said calmly. (Momonosuke and the cowardly deserter king must die.)
