Danzo's Return, Inheriting the Darkness of the Shinobi World

Hokage Office.

Tobirama Senju held the recovered Impure World Reincarnation research materials in his hands, looking over the experimental notes he had personally written ten years ago.

For a moment, countless emotions welled up within him. It felt like a child burying a time capsule, only to unearth it years later. The traces left by the middle-aged Tobirama were now being reviewed by his older self.

Ten years. Did anyone know how he had spent them?

The Impure World Reincarnation he had thought about day and night could finally resume its research.

In his delight, Tobirama lost his usual sternness. "As expected of you, Toji. You easily accomplished what I could not."

Toji sighed softly, his expression turning serious as he spoke earnestly. "Tobirama, if we truly succeed in developing Impure World Reincarnation, how do you intend to use it to reduce the village's casualties?"

Drawn in by Toji's mood, Tobirama's smile faded. "My idea is to combine Impure World Reincarnation with Mutual Multiplying Explosive Tags."

"Ninja revived through Impure World Reincarnation possess immortal bodies. Paired with Mutual Multiplying Explosive Tags, they would become Konoha's strongest line of defense on the battlefield."

So that really was it.

At the cost of desecrating the dead and bearing sin, all for the sake of creating a batch of human-shaped walking bombs.

Tobirama Senju, you were too naive.

Hearing him state that goal aloud, Toji actually felt somewhat disappointed.

If all they wanted was to make human-shaped walking bombs—

Weren't there plenty of death-row
