Cool Devices (クールディバイシス Kūru Dibaishisu?) is a series of animated hentai pornographic videos. Released as OVA, the series consists of eleven mainly unrelated episodes referred to as operations and is most noted for its very extreme sexual content, most of which center around BDSM and similar fetish themes as well as its high production values (compared to other hentai titles of the time).

Originally, the series was licensed in North America by Nutech; because of litigation, the company lost the license,[citation needed] which is now owned by Critical Mass.


The United States releases of Cool Devices are rated "18 and up" by the distributors.[citation needed] However, imports of this series can not be legally brought into Canada due to its exploitation of sex.[1]
