Lonely Yuri

Gods are the ones that defend the world. Demons are the ones that torment it. A fallen angel simply roams it, doing as they wish.
The existence of men is unneeded, unessesary. So they should perish, as is my belief.
Being not a normal high-schooler from the beginning, Todoroki's life changes when she befriends a possible murderer. Embarked on a journey full of angels, demons, life and death, the feeling of having a true purpose is made.
Her true purpose, is to become someone evil. Someone dark and deceptive. Yet, all she wishes for is an escape from the loneliness, the darkness, to live a normal life. But the only way to escape that abyss is to accept it's existence.
So, facing it, standing firm. . .Being someone that even the darkness shuns. Being darker than darkness itself, is the only escape from it.

This story is what people tend to refer to as 'dark' and if this is okay with you, simply proceed.
