Naruto: Return of Yahiko

Yahiko, a former ninja of Hidden Rain Village, later sacrificed himself for his companions in the conspiracy of Sansho Hanzo and Danzo. After the mysterious masked man appeared, he turned the tide, repelled Hanzo and Danzo, and later assisted Nagato in revenge. And just after killing Hanzo, Yahiko's corpse, which had been transformed into Pain Tendo, was reborn with memories that did not belong to this world. Everything, what is the reason? What will Yahiko, who has absolute power and everything in the world, do? "No matter what, even if I am alone, I will fight to the death with the outsiders that day!"
