Toru and Akari find and defeat Clay, learning he's been scared of Emperor Arthur after fighting him and Chaika since she was beheaded by the leader of the Eight Heroes, King Stephan Hartgen, so he gives up Arthur's ears so he won't have to see Chaika or the remains again. After acquiring Arthur's ears, Guy appears and tells Toru and Akari to head to the secret island but both of them are now wary since Guy knew about the other Chaikas. Meanwhile, Shin informs his master Stephan that all of Arthur's remains will soon be arriving which Stephan promises his daughters Irina and Alina they will get to see it. Meanwhile, Toru and Chaika have an argument as the latter wants to find the secret island which the former refuses believing it's dangerous which leads her to firing Toru.
