The Last Fist
The bullet finds its mark and Tsuna gets knock backwards by its force. Bermuda realizes that it is the dying will bullet and concludes that Tsuna must be alive. He flies towards Tsuna and attempts to stab him. However, Tsuna's hand emerges from of his chest and stops the attack. Shocked, Bermuda flies back while Tsuna stands back up. Tsuna is reborn and declares that he will defeat Bermuda with his dying will. He removes his gloves, surprising Bermuda and everyone else. Reborn mentally comments that weapons are not needed because Tsuna just has to believe in himself. He thinks to himself that Tsuna has finally understood the ultimate dying will because he had saw it in Tsuna's flame yesterday.
Flames engulf Tsuna's entire body and he tells Bermuda that he is ready to die in order to defeat him. Bermuda recognizes Tsuna's mental state as the last stage of the dying will. Tsuna questions if he is in the same state as Bermuda when he created the Flame of Night, which Bermuda affirms. Bermuda recalls that when he was lost in despair, he had become an epitome of vengeance towards Checker Face. He further explains the Flame of Night was born when pure dying will without the slightest hint of hesitation had consumed his body.
However, Tsuna begs to differ and thinks that his dying will originates from hope. Bermuda shouts that it is nonsense and appears behind Tsuna. Before he can land a blow, Tsuna punches him. In disbelief, Bermuda attempts the same move, but the result remains unchanged. Tsuna explains that it is possible because he is using his dying will. Bermuda unleashes a barrage of attacks on Tsuna, which he does all. Jager is dumbfounded and comments that Tsuna is blocking all the attacks. Frustrated, Bermuda prepares to use his 100% lethal final technique.
