I'm here to announce that the DLC 《Another Season Episode》 will be updated next month with chapter 2, which is Sio/Yuuka's story and also will have some new characters joined!
Chapter 2 is also included in the free DLC which means anyone who owns the original game will be able to play it, and there will be a few more chapters after this, so stay tuned!
You may check the DLC store page for more information and also the new trailer.
