Welp...
"Autoing (also known as "bunnying" in certain RP communities) is the act of controlling another RPer's character without their permission. This may take many different forms - from describing another player's character taking a certain action that their player did not make them take to forcing a hit on another player's character in a battle - all of which are equally annoying and none of which are considered acceptable behaviour."
I guess you're kind of right, but with how you said it and emphasized the words "no one", it seemed that you were saying that no one should have seen her reenter or her disappearance (which follows under the portion I bolded). I mean, if it didn't fit your character at all, then I'm sorry for the confusion and for the mistake. But saying that your character came in unnoticed would be wrong XD since, as I've explained from my very last post, that Miel had noticed her disappearance and had Laplace go and see her, while Butch could see everything since she's at the very back of the class. Plus, your character made a stunning performance, so who wouldn't notice her disappearance? Maybe Mr. Allen wouldn't notice her reentering into the class until he turned around in his chair, and maybe a few students who didn't pay attention, but still.
Not sure if this is minimodding either, but eh :/ I'm just really confused, and wanted clarification.
