裏切りは僕の名前を知っている - Season 1 Episode 21 Aflevering 21

Reiga commands Cadenza to retreat by invoking his summoner's right, enveloping Cadenza in chains, which Kuroto explains, will burn through him if he still refuses to obey Reiga's commands. Cadenza remarks slyly that since Reiga already has 2 General-Class Opasts under him, his powers are currently split, making him weaker. Breaking the chains easily, Cadenza turns on his master as befit his title "Master Killer" and they exchange blows. Reiga is overpowered soon enough but as Cadenza readies the finishing strike, Luka appears and blocks the attack, saving Reiga. Telling both Kuroto and Senshiro to escort Yuki back to the mansion, Luka promises Yuki that he will protect Reiga if that is Yuki's wish. As both Luka and Cadenza release their powers in preparation for a duel, the other Zweilts appear. Cadenza aims for a sneak attack at Yuki but is stopped by Reiga, yet again coming to Yuki's aid, surprising everyone. Yuki is even more assured that it is Kanata who wants to protect him and confronts Reiga. However, Reiga mentions that it was just his plan not to kill Yuki so early in the battle and reiterates the fact that Kanata is now gone. As Yuki continues to deny Reiga's words, Cadenza finally asks Reiga where his loyalties lie.
