On the page 11 i looked at the witch on the broom and my reaction was "Dat ass!" xD Just look at it, it's so weird :D Even the Neko-sensei (Fotgot her name so i'll call her like that xD) pointed it out with her pointer (/stick? :D)
It would have been great if this was a series instead of just a one-shot. It just seems like such an ambiguous ending which would have provided such a great series premise.
