Ishuzoku Reviewers

There are several brothels with "succu-girls," who have succubus blood running through them, for each variety of humanoid species in a globe where prostitution is permitted. Each species has a unique perspective on how each succu-girl performs for them, hence diverse brothel patrons have evolved into reviewers who rate their interactions with various succu-girls and post their ratings in the neighborhood tavern. A human named Stunk, an elf named Zel, and an angel named Crimvael are the three main characters of the series.
