After Arios' betrayal as well his second defeated by Rein, Aggath now holds a hatred towards his falsely friend after what happened to Leanne. After realizing Arios' true filthy nature, Aggath chose of betraying Arios over vengeance on Rein when he lost all of his respects for his so-called "friend" and attempting to kill him to avenge Leanne but instead he failed and got killed by a group of demons under Arios' orders, because he was compromised by Monica Eclair.
