The game is the first full-length release under the holo Indie brand, which Cover Corp describes as a "collective term for a game brand for fan games created using the game creator support program." The program is designed to support derivative works by independent developers. CCMC, a wholly owned subsidiary of Cover Corp established on October 10, 2023, handles game production support and publishing for the brand.
The story is set at "HoloHigh," a prestigious academy divided into two factions: the rebellious second-year group "HoloMyth" and the discipline-oriented first-year group "HoloCouncil," appointed by the school to maintain order. The conflict between them escalates until a mysterious incident occurs, with Gawr Gura emerging as the prime suspect. Players must navigate the faction tension, interrogate suspects and witnesses, and piece together the timeline to save Gura from suspension.
Developer VTAC Games said in a comment: "HoloTrials is a free mystery game made by fans, for fans. We created it with love for the hololive community. We aim to make it an accessible entry point for newcomers while also satisfying existing visual novel fans." The game uses a lineless 2D art style with fully animated sprites.
