Four broken people moving through a rotting city with nothing left to lose. The OVA strips away plot machinery and just watches them survive, reload, light cigarettes, and occasionally remember why they're still alive. That's the entire story, and it's enough because every frame costs something. Heine's blank stare carries more weight than a dozen anime protagonists screaming about their dreams. This isn't trying to be epic or grand. It's just four damaged humans refusing to disappear, and that refusal is everything.

In a future European city that reaches far underground, with secret, dark levels that hide clues to the past, four dangerous people make their living on the streets and in the depths below. Mihai, a former assassin, has come back and now lives with Kiri, who runs a restaurant. Badou is a one-eyed mercenary who is rarely without a cigarette. Naoto is an orphaned young woman who fights with a katana. Heine is an albino gunman whose body was changed through genetic engineering, and Badou sometimes works as his partner. The four-episode OVA is an action story set among the city's deadly trades.
