I'm a little intrigued by this Geass Canceler. When you think about it, it can get quite complex with Lelouch's ability. Sure, when you apply it with Rolo or Mao's Geass, it would be quite simple how the canceler would act, it would simply prevent them from using their Geass or interrupt them.

On Lelouch case however, it cancel orders. Which brings me to the point, do the canceled victim remembers it was Geassed? Shirley remembered stuff because Lelouch's command specifically told her to forget, so canceling the order would make her remember. And what about orders that were already executed? Kallen's case for example. I honestly don't think anything would happen to her in terms of memory, but I think canceling her would give Lelouch the ability to Geass her again.
