Transmigrated into Naruto.
Baichuan is the same age as Naruto and has become the illegitimate son of Jiraiya, the Pervy Sage.
Mount Myoboku is in an uproar!
The Child of Prophecy is actually a "twin": one in the open, the other in the shadows.
To save the Third Hokage.
To save his father, Jiraiya, and all those other lives that ended in regret, Baichuan decides to become a villain.
He's lecherous and greedy, and a master of cheating at gambling.
With the Six Vein Divine Sword in one hand and the sinister Kun Fist in the other, his Iron Mountain Lean smashes Susanoo, while his Lightning Kun Palm beats Orochimaru to a pulp!
If good people never live long...
Then in this filthy world of Naruto, I'll be the villain who makes everyone tremble in fear.
