What is DEMONS NIGHT FEVER?

DEMONS NIGHT FEVER is a strategy simulation RPG developed by Drecom and published by Arc System Works. Players follow Killshiro Katanaka, an overworked programmer who forms an unholy pact with Giga Super Death, a fallen supreme devil transformed into an infant cat, to battle divine forces across warping astral realms.
Each campaign run requires managing a strict thirty-day calendar deadline per chapter across base activities and grid combat. Battles rotate through four phases where players manually control Killshiro to sacrifice, teleport, and detonate autonomous allied peons, spending earned perverse points to build character stats.
