The Summer Pockets game that came out back in 2018 has an anime adaptation in the works, though they didn’t offer up any details regarding the project or timeline.
The game itself has had several releases across different platforms, including in English via Steam with an updated version as Summer Pockets: Reflection Blue.
The folks at Key ran a special end-of-year live stream event earlier in the day in Japan and it had a really good reveal for fans of their works.
