But Rengoku loves you... Alot. And he can't bear the thought of losing you.. he was fighting... So much... Just for you... He was fighting for you... You were trying to get to him desperately calling out his name. "RENGOKU..!!" you yelled. But it was to late... Akaza punched through his stomach... Right at a vital spot. "no I can't die... I can't..! I need to continue fighting...! For her..!"
