Naruto: I'm the Little Fragrant Pig in Tsunade's Arms

Going with the transmigration trend, he is reborn as Tonton, the little pig in Tsunade's arms.

Though he can't speak, this sweet little cutie grows into Konoha's second-in-command, a mighty figure who shakes the Shinobi World.

Inside the Akatsuki:

Pain: "Itachi, go to Konoha with Kisame and retrieve the Nine-Tails."

Several days later, Itachi and Kisame returned empty-handed. Pain was baffled. Itachi replied, "The second-in-command has returned to Konoha."

"The second-in-command?" Pain didn't understand.

Kisame used both hands to show how big it was, looking utterly helpless. "A little pig."

Pain sneered and went himself.

Two days later, he returned in a sorry state, gathered everyone for a meeting, and drew up a special operation plan with the codename: "Pig Annihilation."
