Ok, so it seems that you need more clarifications for this, huh?
So, first things first:
- The teachers are there to look after/guide your characters. Nothing is disallowing them from taking part, especially if things get out of hand for the students. The way they'll behave is really a choice of their own.
- If establishing a post order is the best idea for you then so be it. Just don't be too attached to it to the point it may slow down the story's progress.
- The team name's part is just a joke on the RWBY-like nature of the RP. The main difference being that Reiko and Aria aren't mad enough to push unsupervised teens off of a cliff, into a forest of certain death... yet.
- The faster you begin the missions the faster we get to the good parts. The teams are supposed to leave the Academy as soon as they've assembled. If that wasn't clear enough IC.
- I guess that's pretty much all that you need to know by now.
