The game lets you control Ai, who pays a visit to her little sister Kokoro who works at Eureka Soft, a women-only game developer company near Tokyo. Despite having not seen each other for a while, Kokoro acts extremely coldly toward her elder sister. In order to discover what changed her, Ai ends up joining Eureka Soft and becomes in charge of the remake of a popular game titled “Yume Utsutsu, the sacrifice, the witch and the world’s end.” The game will show the various conflicts and emotions that game developers can go through and the blossoming of love between girls, all fully voiced. It will also have shocking developments and endings, something actually quite common in overly cute Visual Novels, and something Shimarisu, the team inside Kogado in charge of the game, already did as well.
