Produced by Pink Pineapple, the first episode of Koakuma Kanojo tells two stories of high school students possessed by "evil" spirits. One becomes a lustful succubus, the other a siscon futanari. If you're feeling intrigued to expand your repertoire of fetishes, but you're yet to find futa art that would appeal to you, right here is your gateway drug. This hentai title introduces some of the exciting possibilities girls with dicks can offer, such as self-sucking and cum eating. The reason I'd call this title a "gateway" is because the first girl doesn't even have a cock. Her succubus tail doesn't look the part but actslike a penis, reacting to stimulus and shooting semen. That's just the perfect scenario to ease yourself into the experience.

The art is standard Pink Pineapple quality: curvy, highly detailed girls, visibly erect nipples, puffy pussies, etc. The stories - or scenarios rather, are simplistic but passable, wasting the optimal bare minimum of time between the action. There's just enough backstory to set the lovely events in motion.

The animation is an adaptation from the original manga by Hisasi. No western release of the OVA is available, but thanks to EROBEAT, a fansubbed version exists.
