Aggath

Aggath was a former member of the Hero's party until its disbandment due to Arios' betrayal towards his other teammates.

Realizing Arios' true colours, Aggath died when he betrayed Arios (or rather it was Arios who betrayed him) and attempted to kill him. He was killed by a group of demons under Arios' orders instead after he was exposed by Monica Eclair in his attempt to defeat the traitor.

His death, along with Leanne's demise, caused Mina to also betray Arios, and she formed an alliance with Rein Shroud upon realizing how hideous Arios truly was. Aggath's death (along with both Leanne and Mina) were soon to be avenged by Rein after he finally killed Arios for his betrayal and delusions.

Appearance
Aggath is a bald man who wore silver knight armor. He also wielded a two handed greatsword.

Personality
Just like the other members of the Hero's party, Aggath deemed Rein Shroud useless as the party decided to kick Rein out, but he still recognized the beast tamer's navigation skills. Later, he made an appeal to bring Rein back as a navigator through the Lost Forest.

Aggath was devastated when he, along with Mina and Leanne, were betrayed by Arios. After the Hero's betrayal and his second defeat by Rein, Aggath now held a hatred towards his false friend. When realizing Arios' true filthy nature, Aggath chose to betray Arios over seeking vengeance against Rein. He lost all of his respect for his so-called "friend" and attempted to kill him to avenge Leanne's death. However, he failed and was decapitated by Arios, because he was exposed by Monica Eclair.

Background
To be added.

Abilities
Aggath wielded an enormous claymore showing he has great physical strength for a human, though he was still no match for Kanade, who easily defeated Aggath using brute force but without using her full strength.
