One Piece: The Half-Blood Ninja Who Hides on the Straw Hat Ship
BTTHFan
Xi Yan, a half-Uchiha and half-Senju, shone brightly during the Second Shinobi World War.
While on a mission to the Land of Water, he unexpectedly found himself transported to the world of One Piece, encountering a sea train bound for Enies Lobby!
On this speeding train, Xi Yan met a boy carrying a destiny.
Luffy: You're a ninja?
Xi Yan: Yes. Luffy: Be my crewmate!
Xi Yan: Sure, since I'm here, I might as well join.
Invited by Luffy, Xi Yan chose to join the Straw Hat Pirates.
He then used his power to help his crewmates rescue Robin and protect the ship spirit, Merry!
During the Marineford War, possessing the invincible eye techniques 'Takemitsukiko no Mikoto' and 'Kitsu no Mikoto,' Xi Yan unleashed a massive Susanoo that wreaked havoc at Marine Headquarters, showing the Marines what true power was.
His two divine weapons, 'Kitsu no Mikoto' and 'Kitsu no Mikoto,' terrified the Marines!
Sengoku: Damn it, this guy's just a ninja, why does he possess such immense power?!
Kizaru: These newbies are terrifying these days~ Akainu: You evil pirate brat, I'll personally.
Xiyan: Come on, let's fight to the death!
In the New World, facing a peak powerhouse, Xiyan decisively unleashed the strongest combination technique of the Uchiha and Senju.
Sage Art: True Several Thousand Hands! Third Power: Susanoo! Susanoo Set Great Buddha!
"If you survive my attack, you can try my Six Paths Power!"
Xiyan, having activated his Rinnegan, calmly stated.
(Momonosuke and the deserter king are doomed)
