The door opened, and Tsunade emerged, exhaustion written all over her face. She told Sasuke, "The surgery was a success, for now. Once his spine heals, he'll regain sensation below the second thoracic vertebra. I also removed every cell that wasn't his own or Orochimaru's. He probably won't be able to use some of those bizarre abilities anymore."
Tsunade was referring to the abilities of the Sound Five.
She had actually wanted to remove Orochimaru's cells as well, but they had already spread throughout Kabuto's body. Forcibly removing them would have killed him.
"..." Sasuke stood, breaking free of his handcuffs and shackles. He removed his blindfold, took the bottle containing Kabuto's blood from his ninja tool pouch, dipped his fingers in the blood, and formed hand seals.
"Summoning: Impure World Reincarnation!"
Bang!
A coffin rose, its lid fell away, and the reincarnated Might Guy appeared!
Sasuke strode into the house and supported Kabuto Yakushi, whose upper body was wrapped in bandages, against his shoulder.
Crackle!
Lightning punched through the ceiling, and Sasuke leaped onto the roof.
"Tsunade, you saved Kabuto this time, and you treated me after Tsukuyomi back then. I won't forget what I owe you. As long as you're Hokage, I won't attack Konoha. That's all. Farewell!"
Whoosh!
Sasuke leaped backward onto the ground on the other side of the house, then vanished into the forest with Kabuto, disappearing into the distance!
The guards stepped forward. "Lord Hokage, are we really letting such a dangerous enemy go?"
"Since they kept their promise, we can't go back on our word..."
As Tsunade spoke, she took out a scroll and handed it to the guard captain.
"This is the location Kabuto Yakushi gave us, where the orphaned Senju child is staying. There's no time to waste. Bring him back
