Wagaya no Oinari-sama (Werewolf Transformations)

(Edit: the original youtube links were removed, so I've replaced them with links from Dutch Bull's site.)

This anime just had a two-parter chock-full of werewolfy goodness!
First off, here's the first wolf-out, episode 21 (Dutch Bull mis-identifies the werewolf's gender).
And there's even more lycanthropic fun from episode 22, as you can see here, here and here.
