Haradachi, a human incapable of using magic, and his sister, a magic prodigy live alone in dark times.. When Haradachi's sister fades out of the picture, what can he do to get her back?

I am Rook, your average shut in NEET, who, surprise surprise, doesn't like to g outside often. Imagine my surprise when I find out that I have this type of Gift, where I am basically the ghost rider, but I found out I'm not the only one I know who has odd powers DISCLAIMER: This is a work of fiction, and take place within the world of Cursed (as I do not know if I should just retcon the story yet) as such, all locations, people, and companies are all owned by their respective groups (please look them up, I am too lazy to do so)
