Ep. 12: Alicia joins Fallen forces while Diablo binds Klem and Rem forgives Alicia after her suicide attempt.

12

Alicia joins the army of Fallen as Edelgard, Eulerex, and she celebrate the return of the true Krebskulm. Shera treats Rem's injuries with potions while Diablo battles Krebskulm, damaging her significantly but failing to defeat her. Emile shields the girls from debris, allowing Rem to reveal she is unharmed, which causes Krebskulm to revert to the little girl Klem. The army of Fallen turns on Alicia for her failure, but Edelgard holds them off and urges her to escape. Sylvie attempts to kill Klem for the destruction caused, but relents when Diablo casts a spell to bind Klem to him as a slave, creating a collar that prevents disobedience. Later, Alicia appears and reveals she sneaked Edelgard, heavily injured from fighting off the other Fallen, into the city and begs Klem to heal her, which she does. Klem orders Edelgard to never kill mortals again. Rem asks Alicia why she did what she did and she reveals her past suffering and desire to wipe out the mortal races. Since Klem will not kill, Alicia attempts suicide, but Diablo stops her and tells her to find a new purpose to live for, then Rem forgives her. Diablo collapses in exhaustion and is embarrassed when all five girls strip and rub against him to donate magical energy. The next day, Edelgard disguises herself as a human and mingles with the people. Alicia leaves for a new journey. Shera and Rem ask Diablo choose one of them and kiss her, but he refuses, as he is a Demon Lord and only does what he wants.
