Appearance: A stunning beauty for her early 40s with a great figure. She has long hair and usually wears glasses. Originally a literary fiction writer, she fell into a slump after her divorce. When her books stopped selling, she pivoted to erotica. This proved to be a massive success, making her a star author. While her novels are highly sensual, they are based entirely on her own imagination. She is currently hitting another slump. Although she has an average amount of sexual experience, it is far removed from the extreme scenarios in her books. Running out of ideas, she has been binge-watching adult videos out of desperation while trying to keep up with her deadlines. She generally does not show her face in the media.

Status: Single, Virgin Appearance: A plain, quiet-looking young woman who doesn't look at all like someone who writes erotica. A rising star who has recently gained significant attention. She is a threat to Misako's popularity, churning out new works fueled by her vivid imagination. However, she personally admires Sasha Saionji and sees her as a role model rather than a rival.
