Through the official websites of hololive and developer Entergram, it was announced that Aquarium, a romance visual novel game featuring Minato Aqua, a virtual idol under hololive, will be released for Windows on October 26, 2023. Physical copies of the game are now available for pre-order, while the Steam version will only be available in digital format. It is currently unclear whether the Steam version will be region-locked, thus international fans will have to wait for further details to be announced in the future.

It's worth noting that the PC version will also include some extra stories based on ideas from fans, which will be collected through official Twitter events. These stories will then be added to the existing PlayStation 4 / Nintendo Switch versions through free updates.

Aquarium tells the epic love story between you, who will assume the role of an aristocrat, and your maid Aqua. In addition to that, two other hololive Vtuber members, Houshou Marine and Shirakami Fubuki, will also make appearances in the game.
