Scarlet Witch

It's been over a few hundred years since the explosion. The dungeons emerged from out of nowhere and people found themselves capable of doing magic. It was hard for humans to accept that fact at first, but seemingly had no choice in it but to adapt quickly, seeing how monsters were also emerging from the depths of the dungeons and terrorizing groups of people. The ones who could do magic were selected by a 'System' that seemingly seemed to have a consciousness of its own creepily enough. It lets you level up, pick a class of your own choice, and select where you put the points in your stat. But what happens when the 'System' has its favorites?
