This one doesn't ask you to care about the crew, it asks you to count them down. Nine people land near Inferno II, a planet already flagged forbidden because the first ship went quiet there, and the OVA spends its runtime turning that roster into meat with the bluntness of a 1987 direct-to-video budget that had no censors to answer to. What keeps it running is the clock: Makuro Kitazato is the last one standing, and a third ship is already inbound, so the job stops being survival and becomes cleanup before more bodies arrive. It is Alien with the philosophy scraped off and the wet parts left in, structured so the story eats the cast rather than developing it. If you hunt late-80s horror OVAs for the ones that commit fully to the kill and don't apologize, this is a 45-minute shift in the abattoir.

Years after a spaceship vanishes near the forbidden planet Inferno II, a second vessel carrying nine crew members reaches it. There they run into a monster that slaughters nearly all of them in short order. Makuro Kitazato is the only one left alive, and a third ship is already on its way. He has to kill the creature before it can catch the new arrivals off guard. A single-episode 1987 OVA, it blends horror with science fiction.
