Dark Shell: Lust in the Cage (ダーク・シェル ～檻の中の艶～, Dāku Sheru Ori no Naka no Namameki) is a 2003 Japanese erotic original video animation directed by Katsuma Kanazawa.

The storyline follows the grisly fates of a group of civilian women in a fictional, war-torn Tokyo, as they are repeatedly raped by the soldiers that are supposed to protect them.

In 2006, as a result of the lawsuit against Nutech Digital by Ken Groove Media alleging breach of contract Adult Source Media acquired the rights to Dark Shell as a result.

The content and bleak setting with sex and extreme violence would appeal to few viewers.
