Leanne

Lin is former member of the hero party until it was disbanded due to Arios lost his status as a hero from his betrayal towards her and the other teammates.

Personality
She is haughty and arrogant and like the others looked down on Rein. But she still admitted that Rein's skill of taming Strongest Races are impressive as far apologized to him when accepted her defeat at his hands (unlike Arios who refused to accept his defeat).

She was shown to be devastated when Arios betrayed her and the other Heroes. Like Aggus and Mina, Leanne now hates a hatred towards Arios for his betrayal and after his second defeat by Rein, she no longer viewing him as her friend/leader when she now viewed him as a traitor.
