Hakuoh intensifies his duel against Benny Haha after realizing his shields endangered his allies, vowing to achieve a Perfect Duel with all defenses intact. Mikuni explains this rare strategy, while Yumama returns after defeating Kokujo and traps Mimi behind an invisible magical barrier. Benny Haha confronts Hakuoh about his past treatment of White Knight soldiers, who confirm he discarded them despite their loyalty. This revelation shocks Benny Haha, who learns Hakuoh’s grief over his mother’s death drove his behavior. Despite this, the duel continues. Benny Haha attempts a tactical shift by darkening the stage, but Hakuoh retains all four shields and defeats him. Benny Haha releases Mikuni and Aizen safely into the sea, urging fair play in the finals before detonating the stage. Knight and Dr. Root arrive at the hotel, witness the explosion, and rush to assist the collapsing structure.
