The story thing with Illai and Asirot, they're brothers.
If you still remember about the special day of the year ( http://www.furaffinity.net/view/31194802/ ), then here it is depicted. But unlike ordinary ghosts, Asirot tied not to the place of his death, and to his killer.

Illai since childhood wanted REVENGE for his mother. And in the end, he did it, killing his father and his brother in one day. Just because he can.

The most annoying thing is that Asirot trusted his brother until his last breath.
