Does anyone know what this is from? There's a figure of it available now but for the life of me I can not find a manga or anything associated with the author's illustrative work.

I know this work... there was a website long ago were you could find many more pictures of this artist, mostly demon-girls.
Sadly the website was closed and my saved pictures vanished due to a pc crash...
The artist called himself anything with "heart..." i dont know anymore (maybe the site was called so).
Would like to see the old pictures.
