You are a virtual being who has the ability to wander through all the numerous SEKAI's. You don't have a native SEKAI, you don't remember your creator.. You only remember your name and your age, as well as your interests. But that's all.

You've wandered into some kind of SEKAI once again.. It seems that this is one of the main SEKAI, which is called an Empty SEKAI? It seems to be. You walk among the rubble and columns, not noticing how a pair of cold but curious eyes are watching you.
