Five minutes before the fight ends on the rooftop, Zoro duels Ryuma in Hogback's lab while Franky guards over the injured Brook. Neither Zoro, nor Ryuma, can gain any advantage over the other, as they keep matching the other's attack. Their attacks quickly destroy the lab, forcing them to escape the room and continue their fierce duel on the roof. As Brook watches on, he realized that Ryuma was holding back in their fights. After an intense sword fight, during which the entire roof collapses to the ground below, Zoro finally defeats Ryuma using a technique which sets him ablaze. Zoro lands hard on the lip of the roof below. Ryuma manages to land on a higher ledge, staggering while throwing his sword Shunsui to Zoro as acknowledgement of his opponent's skills. Ryuma collapses in a bout of flames and Brook's shadow is finally returned to him, to his great joy. Zoro acknowledges Ryuma's skill as a swordsman and says he wishes he could have met Ryuuma before he died. He also agrees to forget the outcome of their fight.
