Don't try to peek behind it or steal it. No nonsense like filling it with glue, either. That's pretty much it.

[The glue thing gets an honorary mention because some delinquent kids tried that one before. It resulted in them finding out the hard way that Hyakki Academy has no rule that prohibits teachers from dealing with unruly kids by ~any means neccessary.~ (He gave those wannabe gangsters a trashing that made them never want to mess with him ever again.)

Looking at Ange, Douman doubts that she's the type to pull practical pranks like that, though.]

Ask away. Answering questions is what teachers are there for, isn't it? But I won't answer any that I don't like, and some will cost you a little extra. [He spreads his arms in a way that lets the smirk on his lips shine through.]
