A kid walks into the wrong dream and wakes up entangled with a creature that feeds on desire. Ryuuhei's brother is dead, the city is infected with twisted wants made flesh, and he's stuck between them with no map and no reason to trust anything he sees. The show treats its premise as a problem to solve, not a concept to explain, which means you're constantly disoriented the way Ryuuhei is, never sure if the next person is real or another manifestation of hunger wearing a human shape.
Ryuuhei's ordinary high school life in Shibuya shatters the moment a strange creature bites him after kickboxing practice. That night, nightmares plague his sleep, vivid and wrong in ways he can't explain. The next morning, whispers spread through the city about mysterious "Drops," and Ryuuhei realizes he's caught between two worlds: his normal routine and something darker that's bleeding through. The creature, calling itself Tris, drags him into a hidden conflict where twisted desires manifest as real threats. Ryuuhei's older brother died under mysterious circumstances years ago, and now the pieces of that tragedy start to make terrible sense. As more people around him fall prey to the same supernatural forces, Ryuuhei must decide whether to run from this nightmare or confront it head-on. This is action-driven fantasy wrapped in urban dread. The atmosphere shifts between mundane school life and genuinely unsettling horror, keeping you off-balance. If you want supernatural action with personal stakes and a protagonist forced to grow up fast, this delivers that experience.
