I love how you've written both Iruka and Kakashi here. I especially love the class scene where Kakashi and the old ladies were seeing entirely two different things, and sadistically inclined Iruka just made me laugh because what teacher isn't a bit of a sadist? Thank you very much for putting this up, I really enjoyed reading it.

Kakashi being a Shinobi, he can see underneath the underneath ;) ANd I think teachers have to be bad-ass out of sheer self-defence...
