The Betrayal Knows My Name - Season 1 Episode 22 To the Final Battle...

Reiga and Cadenza retreat to Infernus, granting everyone a temporary reprieve from battle. Having pushed the limits of his power, Yuki loses consciousness and collapses. Witnessing the damage Yuki suffered in battle, the Zweilts gathered at the Kamakura mansion renew their promise to end the war. The doctor warns Tachibana and Luka that if Yuki uses his power again while he still lacks control, Yuki will die. While Yuki and Takashiro are bedridden, Elegy gives Hyde, the surviving Twin Opast, her blood to drink, enabling him to power up. Then the three Opasts attack the Kamakura residence. The Zweilts put up a fight. When Yuki tells Luka he intends to join the fight, Luka goes in his stead, leaving Sodom to guard Yuki. However, Yuki is unable to remain behind in safety and forces himself to go to the fight. As Yuki summons his power to help the Zweilts, Reiga arrives and steals Yuki away, then the three Opasts withdraw.
