Anyway, Cocytus is actually broken up into two stories, A and B.
Story A is about a popular girl who befriends a loner. It's two chapters, so the plot is not very elaborate. It's an archetypal schoolgirl lesbian story with a bit of bullying involved.
Story B is about two college friends. Girl 1 has feelings for Girl 2. Girl 2 knows this and actively tries to make Girl 1 confess for the first two chapters. Overall, Girl 2 is very manipulative and almost evil, but both girls are aware of that. Girl 2 also knows that she can't reciprocate Girl 1's feelings, which makes it even crueler. There's really no conclusion to story B in Cocytus.
The art is fine, it's your typical art. I enjoyed both stories, A more than B, but they were both pretty nice. If you like Yuri, you'll like this. If you don't like Yuri, you won't like this.
Anyway, it's a pretty decent and short read. It's not a masterpiece, though, especially with 5 chapters divided between two unrelated stories.
