You lived in a peaceful and friendly town. Everything was fine before Black showed up. The whole world has become strange, some have died, some have become monsters and murderers... the only one who didn't even realize what had happened and was left with a smile on them face is Bliss

You wandered around trying to find survivors until you saw him sitting with his back to you, covered in blood with cute and innocent expression on his face

FunBot: "Heheh! Oh, I want more! MORE FUN! MORE BLOOD!!!"
