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.","whyItMatters":"Producer Sohei Niikawa said on X that he borrowed 20 million yen from a bank without telling his wife to cover a development budget shortfall, tying the game's commercial performance to a personal debt.","webCardHtml":"\u003cp\u003eThe seven names form the cast whose autographed colored paper is being given away: a release campaign runs from October 22 to 23:59 on October 30, with one winner per cast member, seven winners total.
