Cool Devices is an OVA Hentai series released in 1995. The series is often regarded as the nastiest and most depraved Hentai series ever produced, and by heaven, is that saying a lot. However, this seems largely to be on account of the widely varying plethora of fetishes and paraphilias on display, ranging from BDSM to incest to enemas and beyond.

The series is an Anthology, consisting of 11 episodes called "operations", each written and animated by a different producer, and with the storylines of each being self-sustained and unconnected to each other; with the exceptions of episodes 5 and 6, and 8 and 9.

Tropes used in Cool Devices include:
