Cool, but just let me get one thing straight: our actions won't affect our real world after we leave the magical one, right? Say for example, the train Chikage is next towards: by the time or before the mooks show up, the train would have stopped, right? And if say, Chikage slams a Mook into a car or a car into a mook, she wouldn't need to worry about the possible collateral damage she's doing, right? Granted she might do it even if she will do major damage, if only to learn she needs to be careful.

Pretty much that. in the good ol' Nanoha style, you could level half of the city while fighting inside the barrier and nothing would happen on the real world.
