Demons’ Night Fever: Anime Expo 2026 Impression

Demons’ Night Fever is an incredibly eccentric, oddball flip on what SRPG players have come to expect from the genre. It is very firmly not Disgaea, and the gameplay loop and combat feel like they have a solid, fresh foundation, even if the writing feels like it’s going to be incredibly hit-or-miss for many players.

For those who see the visual similarities and know the history behind Demons’ Night Fever‘s origins — being helmed by now-independent Disgaea creator Sohei Niikawa — a first glance might suggest this game is Disgaea in new clothing. My biggest takeaway: it’s not. In fact, it’s quite different, especially on the gameplay front, in a quirky, inventive, and intriguing way; Demons’ Night Fever is a game marked by eccentricity. An overflowing amount of eccentricity. At Anime Expo 2026, I was given the chance to try out around 45 minutes of the game, and while I walked away with a good handful of answers, I also found myself with a decent pocketful of questions.

Demons’ Night Fever has a relatively simple but entertaining premise: Giga Super Death, essentially the devil but as an adorable but wicked cat, was one step away from killing God. Unfortunately for him, he came just short and was turned into a baby. However, Giga Super Death had been planning for this and thus activated the “Demons’ Night Fever” resurrection program. In a twist of fate, Giga Super Death’s ritual ensnares the game’s main character, Killshiro Katanaka. Killshiro is a gloomy, bitter, miserable man in his late 20s who works at an unethical game corporation. After suddenly passing out from the Demons’ Night Fever ritual, he finds himself meeting Giga Super Death. Together, they form a pact to kill God and do as much evil as possible.

On the whole, the writing is quirky and somewhat entertaining because of its bizarre, exaggerated nature, but it probably won’t be for everyone. There isn’t a whole lot of nuance, and some lines in the demo were seriously eyerolling. Prior to falling into the Demons’ Night Fever ritual and meeting Giga Super Death, Killshiro laments being a virgin at 29 and claims that in one more year, he’ll be a “full-on incel wizard.” He also noticeably harbors resentment towards his ex-classmate Mary Haley, who became a world-famous idol and is due to stand on the side of God in the full game in an attempt to “save” Killshiro, though she did not appear in the demo. The biggest question story-wise is how Killshiro and Mary are going to interact, especially in a game with so few characters.

The more interesting element of Demons’ Night Fever is its gameplay and combat. Essentially, the gameplay loop has players collecting “Peon” underlings, essentially character units, and then performing Misdeeds of various flavors, be it murder, kidnapping, etc. Through Misdeeds and gathering resources, Killshiro slowly becomes more powerful and can upgrade the Peons and gain new abilities, including positional advantages or actions that allow him to exploit Peons, such as draining their health or killing them, which basically turns them into high-damage bombs on the field. While doing all of this, players must account for deadlines on a calendar, meaning they only have a certain number of in-game days to balance raising their stats and strengthening their Peons before clearing mandatory event battles.

Given the relatively small slice of the demo, it’s difficult to say how well this gameplay loop will hold up over the full game, but it felt intriguing during the demo. If Demons’ Night Fever ends up being quite long, I can see how the loop would become tiresome without some sort of changes introduced later. That said, killing Peons is quite fun, and players can resurrect them for significant stat boosts. Battles themselves were much more interesting due to the sheer advantage and entertainment of murdering your own allies, with some truly chaotic moments. As someone new to SRPGs, I felt a bit confused by the systems at times; it’s quite a lot to balance and manage, with some engaging but slightly overwhelming complexity. That said, by the end of the demo, it felt like everything started clicking into place.

As it stands, Demons’ Night Fever is an incredibly eccentric, oddball flip on what SRPG players have come to expect from the genre. It is very firmly not Disgaea, and the gameplay loop and combat feel like they have a solid, fresh foundation, even if the writing feels like it’s going to be incredibly hit-or-miss for many players. Blowing up your own Peons is a hell of a good time, though, and I’m excited to see how the strategic depth of this game plays out over a significantly longer runtime.
