Arc System Works has moved Demon's Night Fever from an unnamed project to a dated release. The game is set for October 22, 2026 on PlayStation 5, Nintendo Switch, and PC via Steam. Digital pre-orders opened on the Nintendo eShop, and the packaged and download versions both cost 4,950 yen including tax. A playable demo is planned for the Sega/Atlus booth at Tokyo Game Show 2026, which runs from September 17 to September 21.
The game is a training RTA simulation RPG developed by Drecom. Souhei Niikawa, known for the Disgaea series, is the producer. Original concept and scenario are credited to Romantoyama, with character design by Yuuji Himukai and music by Tatsuya Yano. The premise follows a programmer named Jaryuin Kyoushirou, who becomes the apostle of a baby evil god, Gigasugoides, and works through a revival program using chapters with day limits. Battles run on a grid in turn-based phases, and servant units act on their own without direct orders. A pre-order trailer features the theme song "Dropout" by syudou.
On September 17, 2026, Arc System Works announced that an official web short manga has begun serialization. The eight-chapter comic follows Kyoushirou, a programmer who hates the world, and Evil God Gigasugoides, who carries a revival program. A giveaway tied to the game's Tokyo Game Show 2026 exhibit offers autographed colored paper from seven voice actors, including Kaori Mizuhashi and Yuya Hirose.
Earlier, on June 3, 2026, the official Anime Expo account announced that Arc System Works would hold a developer panel on July 4, 2026. The panel would feature an unannounced new anime-style title alongside updates on Guilty Gear -Strive- and Demons' Night Fever, with producers Ken Miyauchi and Sohei Shinkawa, and designer Satoshi Hiyae.

Arc System Works released the simulation RPG Demons Night Fever on October 22, 2026, for PlayStation 5, Nintendo Switch, and Steam. The game costs 4,950 yen including tax for both packaged and download versions, and it supports one player offline. Developer Drecom and publisher Arc System Works call the genre a training RTA simulation RPG built on the concept of enjoying evil. Battles center on the Servant Overwork System, where players blow up their own minions with Kill Skills and Sacrifices to clear enemies. At the hideout, five actions (Evil Deeds, Plunder, Recruitment, Treasure Hunting, and Vice Sublimation) earn Vice Points, but every action advances a turn. The story follows the evil god Gigasugoideath, who turns into a baby, and Kyoshiro Jaryuin, a young man who hates the world. Each chapter boss defeated changes the scenario, switching to situations such as becoming a monster to beat a sentai hero or a witch to beat magical girls.
