An idealistic painter rediscovers the beautiful mermaid that served as his boyhood muse... but she's living in a sewer and has horrible golf-ball-sized pustules breaking out on her stomach. And that's not the disgusting part of Mermaid In A Manhole.

Rather, this is the disgusting part: The painter gets her home, and puts her in a bathtub. The pustules rapidly spread to cover her entire body, and she convinces him to lance them for her. This causes her to act like she's climaxing (in a gore-gasm. Get it?) And then he collects the weird pus that drains out of her in a bucket, so he can use it to paint more pictures of her. Because it's Art. Don't you see?

Oh, and you shouldn't watch this clip if you're easily grossed out or offended. Really.

Later, the pustules start having worms and creatures coming out of them. It's like a metaphor. Mermaid In A Manhole is part of the Guinea Pig series of Japanese horror.
