Very, very funny
This was great! I was expecting something along the lines of a straight parody, but you really managed to add a nice and surprising twist to the whole concept. And on top of that, you even voiced it in Japanese!
The only small thing that bothered me was that it did really borrow it's style rather heavily from typical animes, which was a slight (note, only very slight) bummer. But then again the style fitted the whole thing rather nicely, it's influences and sound being mainly japanese and all.
Overall, great stuff.
