Sister of Iesu

Sister of Aies is one of the Supporting Characters of the Ore dake Irerukakushi Dungeon.

Personality
She hated people being hurt the most.

Background
Aies' younger sister was suddenly abducted by the King's guards and forced to participate the Noble Battle, but she was killed in it, having her body dumped outside the city.

Her death is the reason why Aies created the S identity and found the Fangs of Counterattack, targeting the same nobility and royalty responsible for her death.
