The Second, Tobirama Senju, possessed many remarkable ninjutsu.
Space-Time Type—Flying Thunder God Technique, S-rank. An S-rank space-time ninjutsu developed by the Second. By using a formula, it allowed instantaneous movement. The user would first leave a Flying Thunder God formula on a target, enabling themselves—or objects indirectly in contact with their chakra—to teleport instantly.

Depending on the battle situation, Tobirama would throw kunai already marked with Flying Thunder God formulas, then instantly teleport to the marked kunai's location, appearing behind the enemy and cutting them down. Striking with a kunai at the instant the opponent believed they had succeeded was one of Tobirama's usual methods of attack. Formula-marked kunai could distract the opponent; when a kunai flew behind them, the
