Just a clarification, this is an OAD (Original Audio Drama), and will lack animation, it looks like it will have anime still pictures at the very least.
The amiami link provided is to the spin-off manga only without the OAD. The version with the OAD bonus is linked below but pre-orders are closed (they probably sold out) https://www.amiami.com/eng/detail/?gcode=MED-BOOK-025382
Amazon jp still has some available here https://www.amazon.co.jp/%E3%81%AE%E3%82%93%E3%81%AE%E3%82%93%E3%81%B3%E3%82%88%E3%82%8A-%E3%82%8A%E3%82%81%E3%82%93%E3%81%B0%E3%83%BC-OAD%E4%BB%98%E3%81%8D%E7%89%B9%E8%A3%85%E7%89%88-MF%E3%82%B3%E3%83%9F%E3%83%83%E3%82%AF%E3%82%B9-%E3%82%A2%E3%83...
Thanks! :D
Here's the wallpaper, and I use Action Launcher 3 as the launcher. It's got some neat features, like changing the search bar, folder colors, etc.
