Long Time Ago........
Humans and Monsters used to work together and help each other as David, The Human King, and John, The Monster King, were friends.......
As years passed, David suddenly grew cold and unkind to both monsters and humans that he wants war against The Monsters.......
John kept on asking why they have to have war, but David refused to talk to him........

Soon, there was war
Many humans and Monsters suffered and it was a time of chaos and destruction........
Finally, the kings ended the war and decided to be friends once again......
But then an AU traveler appeared.....
The AU traveler seems nice and kind but deep inside their heart is evil.....
Soon The AU traveler attacked and ended all of the humans......Including David......

To protect their kond
John and some monsters go to The UnderGround and shielded around Mount Merculas ( MT Ebott ) with a powerful spell that bans anyone who does not belong to the AU......
It was like that for centuries........
Until a skeleton girl proved that there are good people out there in The Multiverse.......
And her name......Is.....Sofia
