Io Ishtar

She was part of the Helman expedition to Ylapu in Rance IV. Her role during the expedition was that of a caster, but her affinity with hypnosis allowed her to take advantage of her unfavorable situation and made her assignment much easier. She gets separated from the group and confronts rance.

Trivia

 * Her last appearance was at the end of Rance IV, where she was hitting on a male on-duty Helman soldier and was thus not seen in Kichikuou Rance or any of the other titles where Helman was involved.
 * During the events of Rance IX, she did not enter the line of combat and is thinking of retiring.
 * She is the first playable character to be from helman.
