The Necromancer Game, a dungeon-crawling game where all players' real lives are bound to in-game outcomes, hides hidden dangers. Milo Chen enters the game personally to approach Taviel, the cold, stoic game prosecutor who has lost all past memories. They fight through multiple eerie Instance Dungeons, recover lost memories to uncover the shared past where they once risked their lives to protect each other, join forces to dismantle the behind-the-scenes scam, and complete mutual redemption.
