Isabeau is a character from Shin Megami Tensei IV.
She is the only female member of the Samurai, a group formed to hunt down demons. She was born into the Luxuries, the noble class. She keeps herself well disciplined and also wants others to follow in her training. There is more to her than what you see, as she seems to be keeping some things hidden. Walter calls her "Iron Face" because of her cold personality.
