What they share
Theysit in Animation / Horror / Science Fiction territory. If that's the register that drew you to Runaway Brain, the second film will land in a comparable space — through a different lens.
What Alien from the Darkness is
Deep space. A distress beacon. A drifting cruiser's all-female crew, dead. Rescuing the sole survivor, Flair, the transport ship Muse detonates the derelict. But Flair carries a contagion. The Muse's crew falls prey to a desperate alien presence. Takanami’s direct-to-video anime leans into the "erotic" side of cosmic horror.
