Mobius. An idyllic world that lets people forget about the pain and problems of reality. Created by a sentient vocaloid program, μ (Mu), reality and fantasy have become blurred, allowing people to relive their high school years in bliss -- but just how real is a virtual happiness?

How it works

Steam login and Steam Guard recovery details appear on your order page.
Know exactly what you are ordering.
Before you buy a Steam account
Ask about offline mode, access restrictions or device compatibility before ordering.
Contact support- Can I play offline?
- Offline play depends on the game and the seller’s instructions. Some games require an internet connection or a separate launcher. Confirm compatibility before purchasing; shared access alone does not guarantee offline play.
- How do I receive access?
- After payment is confirmed, open your protected order page for the available login details and access instructions. Keep your order link for later.
