The red moon hangs over everything, and the survivors left behind aren't just fighting monsters, they're fighting the ones next to them who might be infected from the inside out. The animation carries weight that most ONA productions don't bother attempting, with facial expressions that make every moment of psychological breakdown land harder than the action sequences. You watch people deteriorate in real time, and the show refuses to let you look away.
A crimson moon hangs in the sky where it shouldn't exist, and humanity scrambles behind massive walls to survive the catastrophe. Most people adapt to this new reality. Others don't. When mental mutations begin surfacing in survivors, some learn to harness their twisted powers while others become living hazards, their corrupted minds leaking poison into everyone around them. The infection spreads like a virus, and these contaminated individuals threaten the fragile safety of the walled cities. Lu Xin sees potential where others see danger. He joins a specialized government unit tasked with managing the mentally afflicted, seeking to understand and control the very powers that make these people threats. But the deeper he goes, the more he realizes the red moon's arrival wasn't random. Something fundamental has changed about human consciousness itself, and the line between savior and victim keeps blurring. Between psychological horror and sci-fi mystery, this story asks what we'll sacrifice to survive and whether some powers are meant to be controlled at all.
