Reituki fanfic There is an evil spirit in which lurks in the dark. A very interestingly seductibe evil spirit. He's never seen in the light, but comes out in the dark. He's different however. Any bad human spirit he finds, he lures them to a more private location by manipulation, and stares deep into their souls with his powerful changing red eyes, killing the bad human and making that human disappear. And usually, this devil does use physical ways to kill someone. However, when he finds that one person that he does want to kill, he can't...because he's deeply in love with tha person.
