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.

Due to Arios' true colours and purely evilness after the deaths of both of her friends, Leanne and Aggath, Mina betrayed Arios and joined Rein for her new goal which is killing Arios and save mankind, where she died along with the Holy Church's archbishop during the war against the demons and Arios himself.

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. Realizing of Arios' full betrayal and true filthy nature after both Leanne's and Aggath's deaths, she has completely abandoned her respects/loyalty for Arios. Like Aggath, Mina also betrayed Arios where she escaped from him and the demons just so she would search for Rein and form an alliance with him and his companions of wanting Arios dead where she and the Holy Church's archbishop died during the war against both the demons and Arios.

Abilities
As a sage, Mina has light magics, believing herself to be the strongest sage. But she revealed to be a weakling only learned are such weak magics when her magics are not even close to those of Tania, when the demi-human from the Dragon Tribe effortlessly nullifying all of Mina's magics. She is also vulnerability when she can die as a normal human where shown she (along with the Archbishop) was killed by the Demons (sent by Arios) for her betrayal.
