Apocalypse-en Goinmuri Piryohaeyo

Synopsis

*“I'm addicted to dopamine.”* In my life, which is already steeped in dopamine, an event occurs that triggers a massive dopamine rush. At a convenience store I happened to stop by, I got a headshot from the clerk, and found myself transported along with other players into the hellishly difficult game \[Apocalypse: Safe Zone\]… And I am the only veteran player who has seen every ending, including the hidden zone, in this game.
