I've witnessed a number of these incidents personally. [ A lot of ninjas have come and gone in her time here before--not to mention some of them are from the past. ] Our teacher was here as a kid while I was gone and that sort of thing.

It's really weird!

[ Also magic doesn't exist in ninja land so naturally she's trying to apply some kind of logic to it only to come up empty handed each time. ]

Just the way things are... it's frustrating, but if that's what it is, that's what it is.
