She is 2 years older than Kurosu and lives in the apartment adjacent to him. She enjoys cooking and murdering males that she invites to her room. Her weapon of choice is a box cutter. She goes to college, but is very antisocial.

Spoiler

She was shot in the stomach by the police officer and had her carotid artery slashed by Kurosu and was believed to have died, but wasn't actually killed. She instead got amnesia after being in a coma for two years.
