She plays a human-like creature that the protagonist, Masuoka, discovers in the subterranean world. "F" is found naked and chained to a tunnel wall. She is animalistic in demeanor, like a feral child, and has vampiric tendencies, subsisting solely on blood. Masuoka takes her home and tries to civilize her, referring to her as a modern-day analog of Kaspar Hauser.
