Outsiders manga volume 1 features story and art by Akira Kanou.

In the first volume, a curious high-school student named Ema finds herself caught in the crossfires of a long-running war. However, she hasn't stumbled upon any conflict, but one from another world involving vampires and werewolves. She is immune to the powers of these other-worldly creatures, but could that attract some unwanted attention?
