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 acts like a wise and thoughtful person but thinking Arios Orlando is the only one who can take down the demon lord makes her mindlessly follow and aide him in the journey which led her to ignorantly deem Rein Shroud useless. She is very conceited thinking she knows and is better than commoners even after her first defeat at the hand's Rein's party member.

However, she was devastated by Arios' betrayal. After Arios' second defeat by Rein, Mina developed her hatred towards Arios and viewed him as a traitor.
