Trying to look for a movie. Help?

[The Caged Demon]

Okay, so I saw a trailer about it, like, three months ago. Sadly... I completely forgot about it, and now I'm trying to find out what the movie was called. I tried google, anime sites, but I just seem to can't find it.

I know it goes along the lines that a girl meets a boy wearing a kitsune mask, and he's a demon and if he touches a human, he'll disappear.

Please help... I'd love to watch the movie. It looked really adorable. (; A ; )

[Makoto Meridon]

It's called Hotarubi no Mori e.
If it looks interesting then you should check out the series Natsume Yuujinchou. It's by the same person.
