The Caligula Effect: Overdose

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?
