A burglary job spirals into something that rewires the entire world in forty minutes. The pacing doesn't give you time to ask questions, which is exactly the point: you're running alongside Shido, drowning in reveals that contradict everything you thought you knew. The action sequences are drawn with real weight, the opening theme hits like a hammer, the ambition is staggering, and then it ends before you can catch your breath. For viewers who prefer velocity and spectacle over coherence, this OVA moves like nothing else.
Humanity's world stands fractured by a colossal barrier, a desperate measure against the creeping plague known as Dark mist. Behind this wall, massive artificial cities called Arks house the desperate and displaced, each one a self-contained refuge from the contamination beyond. Shido Enishi works the streets of the ninth Ark as a private detective, handling the small cases that keep him afloat in this stratified society. When a routine job to apprehend a burglar lands on his desk, it seems like easy money. Instead, the capture pulls him into something far darker: a conspiracy that reaches into the highest levels of Ark governance. As Shido digs deeper, the walls of his understanding begin to crack, revealing uncomfortable truths about the barrier, the cities themselves, and who really controls them. What started as a straightforward bounty transforms into a race against forces determined to keep secrets buried. Sometimes the simplest cases carry the heaviest consequences.
