Original character by Wokashiya. She is a policewoman whose job is to arrest illegal aliens (literally). Sarutahiko Kanae is her workmate. Unfortunately, she is always strapped for cash and trying to find good part time jobs.
Wokashiya once created her variant[1] for a NSFW pixiv project/universe[2]. Strictly speaking, she is not related to Ayako in her original universe.
