Shinmai Maou no Testament

Synopsis

Basara struggles to fight against Zolgear. After temporarily disabling Basara with an erotic illusion, Zolgear faces against Maria and shows her the gruesome remains of her mother. Seeing the grim aftermath of Maria's mother, the immense power within Mio awakens. While successful at initially containing it, Mio's inherited and natural strength proves too powerful for Zolgear to obtain after losing his right arm. As Mio exacts her revenge to Zolgear for slaughtering her foster parents, Basara prevents her from doing so, otherwise Mio's future would be tainted with despair and hatred. As Zolgear retreats, Shella—Maria's mother—reveals herself alive and well. Outside his lair, Zolgear faces with Lars, whom the latter thought to be dead; Lars explains that he substituted himself and Shella with his puppet dummies to escape death and intends to kill Zolgear himself to avenge the death of Mio's caretakers who also fostered him as a child. As Basara and co. escape Zolgear's lair, the barrier restraining it disappears, thus allowing it to alter itself back to its original form—a giant demonic monster. Trapped inside the beast's belly, Zest guides Basara, Mio and Yuki into the vital core of the monster and destroy it. (Source: Wikipedia)
