Game in development for 2026 for Switch, PS5, Steam
Arc System Works revealed on Wednesday during the “ARC SYSTEM WORKS Showcase 2026 – June 24th” livestream a new gameplay trailer for Disgaea creator Sōhei Niikawa and SuperNiche’s new game Demons’ Night Fever.
The game will debut in 2026 for Nintendo Switch, PlayStation 5, and PC via Steam.
Arc System Works describes the game’s story:
This is a story of another Earth, different from the one we live on.
Giga Super Death, the most wicked Devil of all, was just one step away from killing God… when suddenly, he was transformed into a helpless baby.
Anticipating such a crisis, he had been working through the night to develop the “DEMONS’ NIGHT FEVER” resurrection program—and finally, it was time to activate it.
Was it a prank of fate, or inevitable destiny? The one ensnared in this suspicious ritual was Killshiro Katanaka, a gloomy young man who despises the world.
Due to their aligned interests, a bizarre pact was formed. This is the story of pure EVIL, starring the Devil himself and his newfound disciple, Killshiro.
The genre of the game is listed as: “Enemies? Allies? Kill Kill Kill! The more you die, the stronger you become! Raising Speedrunning Simulation RPG.”
Tatsuya Yano (former Gust and Atelier series composer) is composing the music for the game and Yuji Himukai is the character designer. Roman Kitayama is credited with the original story and scenario.
The game stars:
Niikawa resigned from his position of Nippon Ichi Software president in 2022 due to personal reasons. He revealed his new game company SuperNiche in March 2025.
Niikawa joined Nippon Ichi Software in 1996. He worked for five years in sales and promotion. He became president and CEO in 2009. He discussed his rise within the company with ANN in an interview in 2012. Niikawa also served as president of NIS America. He is often credited with the creation of the Disgaea game series.
