Hades

Okay, the description thing doesn't give a lot of space so I'll tell you a little more down here. Again, same world as ANWA but it takes place about 200 or so years before ANWA takes place and also pre-CCOR times (if you don't know what the CCOR is, it's not essential but A Night Without Armor will explain it).
"He has no name except the one given to him by the underground society, HADES, an elite league that protects the people from monsters, demons and those who deal with them. Kage, as he was dubbed, is given a new assignment that is crucial, not only for HADES but for the world but when mysterious deaths of certain people occur around him, deaths he is soon blamed for, Kage must look deeper into the Society he cares nothing for to get some answers, avenge his given name, and save the world that has always been against him."
