Huh. There was a request for this artist's stuff earlier this year actually.
Good News: There is a full version with the monster actually slashing her and - most impressive - sound.
Bad News: The artist's Pivix actually doesn't have the full version. They originally hosted everything on a website that has since gone down. I guess when it went down, they lost a lot of their stuff. So for those who've seen their whole archive before the site went down, their Pivix page is painfully disappointing.
Better News: Someone managed to save everything before the site went down. Deep in the Animated Gifs thread on /g, there's a link to a working Mega that contains (as far as I can tell) the whole archive. It includes the full version of this one, as well as all of the artists other amazing animations and still art.
Best News: I'm a nice guy, so I went and dug out the link: https://mega.nz/#!aIAhnZpY!soVrLjUG80jet65GvmZADKT4dRV5WttTFa1eeRaDJCY
It should still be working.
