[A grim reaper. He had heard the term before, what Westerners called the shinigami. If he didn't know better, Aizen would have thought that the death scythe was a zanpakuto, but there were different worlds accounted for here and he would not presume that this man was from the same world as him until given proof of it.]

My immortality has nothing to do with what I am, but instead something that I possess. I could be called a grim reaper myself, though the term shinigami is what is used for us.
