A curious girl found during Otsuu's exploration in the underground caverns.
She is powerful enough to rule the denizens of the underground caverns, but she seems to have a hard time saying her lines straight, and can be found tripping on herself, which makes it hard for many to take her seriously.

At first, she called herself the "Demon King," defeating the many Marchens in the underground caverns, but now that she gained friends, she apparently "changed jobs," and is now a self-proclaimed "Hero."
