He returned with his group and duelled Benchan and defeated him but then when Katsuta arrived and saw Benchan defeated he challenged Onsen and duelled him. This was Onsen's first time to face off Katsuta's "Victory Mode" and lost to him. He usually spends his time in a hot spring (referencing Gallows Cebu Kaiser's affinity for hot springs).
