Gokudera was heavily injured by Ken who attacked him from behind while Gokudera's attention was focused on Chikusa. Gokudera then fell downstairs with heavy bleeding. One of Birds's birds appeared and said that Gokudera was beaten and Gokudera cursed the bird until he heard the bird began singing Namimori School anthem and noticed Hibari's tonfa on the ground. Ken and Chikusa approached him with Ken laughed at him when Gokudera threw his dynamite to the wall behind him. Gokudera only smiled and as the smoke cleared, revealing the injured Hibari who then said to Gokudera to let him handle the rest, which Gokudera agreed to. Ken used his Lion Channel and attacked Hibari but easily defeated by him and was tossed out of the window.
