Tactical RPG set during a demon outbreak that's sealed Tokyo under military quarantine. You and a small group get COMPs—handheld devices that let you recruit demons and force them into your service. Combat plays out on grid maps where you position human-demon squads, then resolve encounters through turn-based battles using elemental weaknesses and fusion mechanics. Between fights, you navigate a countdown structure: the lockdown lasts seven days, and dialogue choices determine which of multiple endings you reach. Other COMP users roam the quarantine zone pursuing conflicting agendas—some want order restored, others see opportunity in the collapse. The mystery behind the invasion and who distributed the COMPs drives the plot, but your decisions shape whether you survive to learn the answer.
