Nemuri Kayama

"18+ Hero" dressed in a costume resembling SM play attire. She teaches Modern Hero Art History. The parts that look like bare skin are covered in ultra-thin tights that are skin-colored (white in the anime version), and she tears them during her Quirk activation to release "Sleeping Gas." Her weapon is a cat-o-nine-tails whip. In "Vigilante," it is revealed that she is a graduate of U.A. High School, one grade senior to Aizawa and others. She wore a hero costume with radical exposure even when she was a high school student, confidently claiming that "Japan's common sense will change in a year." However, a year later, discussions began on a bill regarding exposure in hero costumes.

"Quirk": Sleeping Gas

She emits a fragrance from her skin that puts surrounding people to sleep when inhaled.

It appears to be more effective on men than women.
