Okpa

Okpa (オクパ, Okupa) is a minor character that appeared in the first episode. Being half-woman, half-octopus, she is probably a cecaelia, though the anime classifies her as a Dagon.

Synopsis
The Oceanfloor Theocracy has lifted their ban on prostitution, and with that in effect, Okpa starts working as a succu-girl. At about the same time, Stunk, Zel and Kanchal start reviewing succu-girl alongside Samtahn, with her being their first entry.

When Stunk, Zel, Kanchal and Crimvael visit The Genderswap Inn, Okpa can be seen in one of the catalogs. This means that sometime prior to their visit, she partners with that joint to serve temporally male-to-female clients.

Reviews

 * "The squirming tentacles were too heavy for my taste. I felt that I was being tied up and tortured."
