While Ren’ai Phase is still in the midst of development Giga has already published a teaser image for their next project. It’s available on a special teaser page here and once again shows the silhouettes of the 4 main heroines. The page itself contains nothing more other than the text “new project” and the main staff names.
The artists for the game will be Akemi Mikoto (vndb), Takako Hitsuji (vndb), and Unasaka (vndb). Whereby Akemi Mikoto is the artist of Giga’s “Kiss” series, so perhaps this new game might be another entry in that series. Takako Hitsuji joined Akemi’s work in Kiss Ato (2014). And Unasaka is also working on the upcoming Sorairo Innocent by Akabei Soft.
As for the scenario, it seems that it’ll have two main writers, Kotoya Tamaki (vndb) and Jiino (Gino?) Masaki (vndb). Kotoya Tamaki worked on some games by Giga before, including Kiss Ato and Harvest OverRay.
In any case, we won’t know more than this until they publish more information.
