A 50-century old legend came knocking at my door on the night of my birthday. My whole life turned upside down since then. To make matters worse, my second little sister is dragged into this. If this is an overseas trip with her girlfriends, I would totally be ok with it because most of her friends' parents are very close to our family. In truth, this is not an overseas trip but a life-threatening job that I don't even want to be a part of. But here we are, a part of a demon hunting group that we don't even know about with people we never even met before. And we inherited powers from this ancient family from the middle ages that we barely know how to control.  

            That's the first part, the second part isn't any better at all because my other sister who's right after me is a magnet for demons ever since I become a part of this crazy group. It's my job as the oldest in the family to protect my sisters from these demons. I have no idea how but i have to get through this.
