OBA-141 Slave Hot Spring Companion Azabu Mirei

Mirei, who lost her husband and is looking for work, happens to notice a job posting for a "companion" that says "No experience necessary." She successfully passes the interview and ends up working at a hot spring inn... However, from the first day, Mirei begins to feel something is off. The outfit is clearly meant to seduce men, and what's more, although it's supposed to be a "banquet," she has to deal with men one-on-one. Later, Mirei finds out that this is a hot spring town famous for its "slave companions."
