I Want to Win! Instant Awakening is the 25th episode of the Katekyo Hitman Reborn! anime.
Tsuna becomes cornered, unwilling to hurt his friends until Leon bursts and reveals some Mittens and a new bullet, the Rebuke bullet. Reborn shoots Tsuna with the new bullet, allowing him to hear others' thoughts and awaken. His Hyper Dying Will Mode is activated, and when Mukuro possesses Gokudera and Bianchi, Tsuna finds a vein on his friends' necks which he hits to temporarily paralyze them, knocking them out and causing Mukuro to not have good enough bodies to possess.
