Ishuzoku Reviewers Synopsis
In a world where there are many different types and prostitution is legal, there are many brothels where the girls in this shop meet depending on the type. Regardless of their race, the girls who devote themselves to this business are called "Succu-Girls" because the blood of the Succubi breed runs through their veins.
Since every brothel and type of girl has different experiences when it comes to sex, some clients have become reviewers who rate their experiences with succu girls and post them on the bulletin boards of local taverns. The series then focuses on a human named Stunk, an elf named Zel, and an angel named Crimvael doing their part work as reviewers.
