More a question to the last chapter, but anyway:

How come that Doranbolt's memory manipulation on himself never wore off? When he was defeated by Azuma his memory manipulation on everyone in Fairy Tail was dispelled, so why was the manipulation he did on himself not released too?

Does he have the ability to really completely delete memories and only the changing of memories is temporary and/or revertable?
