Zero

Zero was a high school student who never liked to talk to people and never stood out. He never had friends due to his personality so when he moved no one noticed or cared. He had planned to stay to himself once again at his new school his sophomore year and on.
He moved to the city Darte which was one of the biggest cities in Taryo where he stay in an apartment building alone. What Zero was to find out his life is going to turn around completely. From multi purpose bullets and bloodsuckers to "other" demons and "other" weapons". Zero was about to experience a huge change in his life that he was not ready for......yet.
