The Anomalous Symbiosis

Niki, the girl who had never come across an unusual force that was supplied by her partner. The force was supplied by mental power but one can only do this with concentration. But what's even more interesting is the fact that her partner wasn't even human. Her mission that was given to her out of the blue, involved dealing with Epsilon, an organization that would stop at nothing until her partner was dead. Will she be able to master this force and put a stop to the evil organization called Epsilon?
