"Plaintive Betrayal" (哀切なる背信 Aisetsunaru haishin) is the tenth episode of the Shinmai Maou no Testament anime series. It premiered on March 11, 2015.
Lars threatens Zest and his master by reporting their act of treason to the demon lord for abducting Mio and holding her in their castle if she does not comply to their trade. Zest eliminates Lars and orders Maria to subdue Basara. Compliant to her new master—Zolgear—who holds her mother hostage, Maria transforms into her adult form to subjugate Basara. Meanwhile, Yuki arrives in Zolgear's lair and clashes against Zest alongside Mio. Envying the bond Basara shares with his servants, Zest is soon defeated as is Maria, who breaks down after Basara embraces her—vowing that he will save her and everyone else. Zolgear paralyzes Mio and Yuki while strangling Zest for her failure in keeping Mio captive. Basara uses his Banishing Shift on Zolgear and eliminates the magic holding Mio, Yuki and Zest. As Basara and her servants rally against the evil demon, Zolgear immobilizes Basara using his mental bondage as he approaches him to obtain his powers for himself.
