The title is most likely the original strategy RPG developed together with a major game company, revealed back in 2019.
Back in June, Mikage LLC—the company formed by former Imageepoch head Ryohei Mikage—updated its official website with info on two more of their upcoming games.
This is identical with a trademark filed by the company back in February of this year, and is set to release in Winter 2022.
Currently, the company’s only officially announced game, which also happens to be the company’s first project, is Criminal Girls X. The first new project is something called “AAproject,” which has yet to be officially announced, but will reportedly release in Fall 2021.
