Alien from the Darkness 淫獣エイリアン OVA 01

While on a government mission far from civilization, the all-female crew of the spaceship Muze finds a seemingly lifeless ship, named the Zogne, drifting in space. They investigate and stumble across numerous dead bodies as well as a single survivor — Flair Mytomeyer, an innocuous-looking girl, who is diagnosed with amnesia after being found in a sleep chamber. The crew bring the girl back to the Muze and treat her with sympathy as a medical patient. Computer expert Hikari begins attempting to decrypt the computer records of the Zogne to find out what happened to its crew.
