This story is basically like Alice in Wonderland, exept Key, Its one of those you wont get untill the ending.
it has a dark mood to it.

Key has no idea what is happening to him, all these things are going on and is comepletely lost and has no control over anything, the only thing he wants is to escape this horible never ending hell and get back to reality.
but you never know, Maybe This is his new reality.
