The Merman, My Man

This is a story between a bloodthirsty merman and a kind and naive researcher. Linda, a researcher at a Japanese maritime university, found herself raped by a lewd merman in a dream. This tempted her to conduct research on this mythical creature. Together with her professor Gary, they set off to sea in search of merfolk. They successfully caught a merman, but Linda was marked as its mate…Was it a human that had caught a merman, or was it a merman who had found its prey?
