A translucent spirit shows up in the scene, usually drawn with see-through skin, floating limbs, and a spooky glow while it messes with the living. Sex tends to lean into possession, phantom hands pinning someone down, and bodies getting fucked by something that can phase through walls or appear out of nowhere. Some comics go extra gross with ectoplasm-style cum, cold breath, and that “you can’t escape it” haunting vibe.
