I wanted everything. But I got nothing. And I died. Frustrated, dissatisfied, unfulfilled. The darkness in my heart is as black as the darkness in which I am immersed in this oblivion. [[ CHOOSE YOUR CLASS ]] When I opened my eyes, I became someone else. Different appearance, different voice, much younger, and in a different world. I'm the villain of this story, and I have some peculiar abilities. I could have chosen any class, but I chose the most perverse one... I will use the abilities and powers of my secret class to obtain everything I desire and assert my dominance over others. It will be a lot of fun!
