Title says all. A balloonie cabbit manufactured by a Japanese company but modelled after a French maid, Cherie is a trained professional in the art of Enjo-kosai - essentially, she is a sex worker, giving frisky employers a great time, and occasionally other favors bundled in, in exchange for treasures, trinkets and shinies.

After a friend helped Mag (in male form, Maq) unload years of repressed sexuality, he hired her on Maq's behalf to clean up the gigantic mess that ensued as a result. She happened to be in Mareatown at the time, having just finished serving another client at the time. Although initially shocked by what his friend had done to him, Maq quickly forgave him once he saw Cherie - for lo, Maq fell immediately and deeply in love with this new hired "maid", who would be getting many a shiny thing if she could prove to Maq that he was a much more experienced lover than he let on, and that embracing his sexuality was worth it in the end - which it very much was, because they became a couple afterwards, with Cherie now working full-time as an actual maid in Maq's fancy house (he's too small to own an entire mansion).

Cherie is a kind, thoughtful and surprisingly down-to-Earth balloon woman who always stays calm and collected, and is ready for anything. She can be sexy or wholesome, and has a multitude of skills and talents besides being very good at sex, among them cleaning, playing sports, drawing, writing and even fighting. Though she's made many friends over her Enjo-kosai career, her best friend is her now-partner, Mag/Maq. The two genuinely love and care for one another, and she will fearlessly protect her/him against any harm, despite being a balloon.

Cherie's build is a very unique one, a trademark of her manufacturer. She is structured like a pooltoy, with numerous valves (disguised as jewels) for inflating different parts of her body, but made of soft-yet-durable rubber instead of latex.
