Mina

Mina is the former member of the hero party until Arios' betrayal towards her and the others as well he was stripped as a hero.

Personality
Mina is wise and thoughtful.

However, she was devastated by Arios' betrayal towards the Hero's Party and he eventually sided with the Demon Lord for his vengeance upon Rein, his friend, as well Mina, her former teammates and humanity itself. After Arios' second defeat by Rein, Mina (as much as Aggus and Leanne) developed her hatred towards Arios and viewed him as a traitor.
