[ Rosario+Vampire × To Aru Majutsu No Index (Accelerator) ] Accelerator, he wasn't defined as a human, he wasn't any saint, hero-- like a certain idiotic ilusion slayer-- and he was sure as hell no angel. He was a monster... a terrifying being, with an equally terrifying power, a power that leads only to one way: godhood. The manipulation of vectors, and the calculations dedicated to it would be difficult for any man... but, Accelerator was no man, he was a monster, a monster in power AND intellect, a prodigy in case. The rude, sadistic, un-godly 15 year old had just lost to the stupid hero, and Accelerator couldn't begin to thathom how annoyed he was, people began to see him as weak, but, it was far from the case, and he would show them. He defeated them without budging a single muscle like he always did, the retarted esper-gifted thugs. Tsk, they were annoying as hell. In the original story, Accelerator would have an unlikely encounter with one of the many sisters of Misaka Mikoto, and he would later begin a quest of justice of some kind... however, this is not the original story. Accelerator doesn't meet Last Order, that fateful day, it never happened, and thus, began a parralel story, one where Accelerator enrolls as a 15 year old freshman into Yokai Academy, a school for... Monsters. ============ Note: This is my first crossover, and my first using such a complex character like Accelerator, I always wondered what Accelerator, the esper monster he is, would be like in a school for monsters. This story will be AU, it became that the second that Accelerator joined this universe. More information of this story will be in the | Bio | chapter. I hope you enjoy this story, and I would like to warn you, that at points this story may be contradicting.
