Kite or Urotsukidoji?
Which is a nastier and more taboo pushing anime movie?
"You gotta be Fking kidding"-The Thing.
Urotsukidoji, hands down. The censored version of it is still NC-17.
Kite is only a hentai because the producers forced them to add a single sex scene so they could secure the funding and distribution (same thing happened to Mezzo Forte) and there are censored versions of Kite that are every bit as functional as the uncensored cut, but are basically a typical R-rated movie in terms of disturbing content.
