Visit Radiant City, designed using the principles of psychetecture to soothe its inhabitants. But something went horribly wrong, and the city instead causes anxiety, insomnia, and madness!

Returning from exile with a mission to recover Radiant City's original blueprints, only one man has a chance of restoring its sanity — the enigmatic Mister X!
