Irma

She's a member of an assassination squad who follows orders from the present Queen. She's known as being a cold-blooded killer, a loner and a perfectionist. In fact, nobody to date has escaped her assassination attempts. Her mentor was the previous leader of the Assassins of the Fang, Echidna. The reason for entering the Queen's Blade was due to the Queen's order to eliminate other aspiring fighters from the competition.
