The who that I really am

Nystro of Din lives a normal life among humans. One day, on his normal routine, he is attacked by a demon, the human's natural enemy! That leads to him awakening a dark power to defeat it! But now everyone sees him as a monster and try to kill him as well? How will he deal with the betrayal from the humans?

(Please keep in mind that at the start I'm still getting the hang of it and only after a few chapter does the story actually get better) :D
