A demon god drags a high school girl into the underworld to save his sister, and the 1988 animation moves like nothing else from that era, fluid, deliberate, gorgeous in its darkness. The mythological premise has weight; this isn't decoration, it's the engine. Watch it for the art, but you'll stay because Deimos and Minako's chemistry generates real tension across the visual storytelling alone. The story cuts off mid-narrative and assumes you know the manga, which means new viewers hit a wall. That's not a flaw if you know what you're walking into.
A high school girl named Minako stumbles into the crosshairs of an ancient curse when a fallen deity mistakes her for someone from his past. Deimos, once a god cast down for loving his own sister, now walks the earth as a demon driven by a single obsession: rescuing Venus from her divine prison requires Minako's body as a vessel. But Minako knows nothing of this supernatural debt yet. She's focused on finding her missing friend, which leads her to the decaying mansion of a reclusive botanist whose reputation carries whispers of something far worse than mere eccentricity. What unfolds is a taut mystery tangled with gothic horror and forbidden desire. The mansion becomes a trap where reality bends, where plants seem to breathe with malevolent purpose, and where Minako's connection to Deimos becomes increasingly impossible to deny. Trust dissolves when the line between rescuer and predator blurs entirely. This OVA captures the unsettling beauty of being wanted for reasons beyond your control, where romance and dread intertwine as thoroughly as roots in dark soil.
