About the Game

Mitrasphere is a role playing game developed by Bank of Innovation, Inc. that presents a world where the sky is covered by a vast sea and golden crystals called Mitra drift down from above. The player travels through this strange and nostalgic setting, gradually uncovering the secrets of the world and discovering how personal destiny connects to the falling crystals. The original online service ended on June 30, 2023, but this offline application preserves much of the main experience so that both returning players and newcomers can still explore its story and atmosphere.
Important service notice: the online version of Mitrasphere concluded its service at 16:59 on Friday, June 30, 2023. This offline app is the official continuation of that experience in a limited form. It is intended for players who want to revisit the world or experience the main story for the first time without needing an online connection. Further information about the service transition is available on the official Bank of Innovation website.
What the offline app includes:
The story section allows you to read through the complete main narrative at your own pace. This is the central part of the app and gives you the full arc that was available in the online version. If you have never played the online version, you can start from the beginning and follow the journey without any prior knowledge.
The map section lets you browse the visual appearance of different zones. While you cannot explore them as freely as in the original online game, you can still see how each area was designed and recall the atmosphere of the places you visited.
The sound section collects songs that appeared in the online version. You can listen to these tracks directly inside the app, making it a useful way to enjoy the game's music even after the online service has ended.
The avatar section supports dressing up your character with weapons and other visual elements that were part of the original game. You can also take shots of your avatar, which makes this feature appealing for players who enjoyed customizing their appearance and sharing or saving images.
The picture book section shows characters and monsters from the online version. This gives you a reference guide to the world's inhabitants and enemies, helping you remember the cast and creatures you encountered during the story.
Please keep in mind that not all content from the online version is present here. Event stories and event zones are not included. Some characters, some monsters, and some songs are also missing from this offline app. The developer has stated that official support is not provided for the offline application, so it should be treated as a preserved archive rather than a fully maintained product.
Playing Mitrasphere on PC with MuMuPlayer is a comfortable way to enjoy this preserved adventure. The story is text-heavy, and reading long narrative sections is often easier on a larger monitor than on a phone screen. The map visuals and picture book entries also benefit from being viewed at a bigger size. When you use MuMuPlayer, you can keep the app open on your PC while doing other tasks, listen to the soundtrack through your computer's audio setup, and manage screenshots from the avatar feature more conveniently. This setup works well whether you are using a Windows desktop, a MacBook, or another macOS machine through the emulator. MuMuPlayer gives the offline app a stable home on your computer, letting you revisit Mitrasphere whenever you want without relying on a mobile device.
System requirements for the app list Android 5.1 or later and a 64-bit terminal. Some devices may not function properly even if they meet these conditions. Because this is an offline application, there is no need to worry about server maintenance or connection issues while reading the story or browsing the included content.
The official Twitter account for Mitrasphere remains available for historical updates and community information. The app itself is best understood as a farewell archive from Bank of Innovation, Inc., giving players a way to keep a piece of the world after the online service ended. For anyone who missed the original game, this offline version offers a straightforward introduction to the main story, the visual design of its zones, and the music that defined its atmosphere. For returning players, it serves as a quiet way to revisit favorite scenes, characters, and songs. MuMuPlayer extends that access to PC, so you can experience the world of Mitrasphere on a larger screen and with the convenience of your computer setup.
