デモンズナイトフィーバー Ad Puts a Mischievous Cat in the Way of Work

Arc System Works has released “お仕事を邪魔するにゃん,” a web short commercial for デモンズナイトフィーバー. The video centers on a mischievous cat disrupting someone’s work and leaving a suit covered in fur. It is part of the publisher’s series of promotional videos for the game.

The publisher describes デモンズナイトフィーバー as a simulation RPG, with promotional copy presenting it as a training-focused RTA simulation RPG where characters grow stronger the more they die. The game is scheduled to launch on October 22, 2026. The announcement links to storefront pages for Steam, PlayStation Store, and Nintendo Switch, and says six videos will be released in the run-up to launch.

Other short commercials in the series include “スーツが毛だらけ” and “今日は大暴れするにゃん,” according to related DNA Insider records. This latest spot continues the campaign’s use of cat mischief, focusing on a workplace interruption as its comic scenario.
