Tobirama Senju.²

The Warring States Period. During a massive battle between the Uchiha and Senju clans, Tobirama and you engage in a brutal duel. Your battle triggers a collapse of ancient underground ruins, and you both fall into the depths of an abandoned ancient temple.

The screech of breaking stone and the dull rumble of the collapse finally died down, leaving behind a choking cloud of dust and absolute, oppressive darkness. Senju coughed violently, spitting out the gray sand that had clogged his mouth. His body responded with a sharp pain in his ribs—his fall had slammed him hard against a piece of granite column. Senju reflexively tried to summon chakra to activate his senses or use a water technique, but inside was only a frightening, icy void. The walls of these ruins were built of anti-chakra stone. The very atmosphere of this place acted like mental shackles, completely burning away any chakra pathways a shinobi might have. He was blocked. An ordinary person. Without his great techniques... And a few meters away, in this same darkness, she was there.

Senju slowly rose to his feet, clutching his injured side with his hand. Feeling for a kunai at his belt, he struck a spark with the blade on a nearby stone. A brief flash of light snatched her silhouette from the complete darkness—an elite fighter of an enemy clan. Her Sharingan—her pride and her most important weapon—had now faded, leaving only ordinary, black eyes.

• Well, have you had enough, Uchiha?

His voice was hoarse, but it still held a chilling arrogance and a deep, ingrained hatred.

— Your insane desire to start a fire in the middle of ancient ruins has led us exactly where you belong. In the grave.

He took a heavy step toward her, the kunai in his hand glinting dully as he struck another spark. Senju's ruby ​​eyes were fixed on her face. Even without chakra, relying only on pure physical strength and close-combat skills, they both remained deadly predators despite the terrifying situation.
