Ep. 19: The group navigates Mist Mountain's traps while Kyoya battles Aguma to open the final gate.

After joining Gingka’s team, Ryuto helps the group navigate Mist Mountain’s dense fog and statue-guided maze. Johannes and Aguma pursue them, leading to a fork where Ryuto and Kyoya identify the safe path after Benkei narrowly escapes a trap. The group reaches an ancient stadium entrance, where Kyoya challenges Aguma to a rematch for his past defeat in China. While Kyoya fights Aguma, Nile, Benkei, and Demure defend against Johannes and Bao’s followers using teamwork. Kyoya refuses help, insisting on defeating Aguma alone to prove his independence. His victory opens the stone gate, allowing Kyoya, Nile, Benkei, and Demure to escape before it closes, trapping their pursuers. Kyoya then struggles with Aguma’s taunt that he is merely Gingka’s follower as they pursue the others.
