First, let me say that as hard as it is to wrap your head around this (if you can't read heaps of Japanese), it is very enjoyable. It IS a H-SRPG, but the emphasis is on the SRPG element rather than just the H. Most of the characters are drawn in a loli-esque style, but I just want to assure you, that they indeed are NOT lolis.

As Print Screen doesn't seem to work with this, I have to use a shot not from the game itself, but has the art you can expect to find in-game as well.

The only thing it's missing is someone with green hair.

Huge, I know. It's worth it though. Fret ye not, for I shall also post a torrent which I shall be seeding for some time. The torrent itself is subject to change, as I don't know if this is the one I used myself. In fact, I'm sure it isn't. So even though I'll post this one, I'll more than likely post the one I used as well tomorrow sometime.

Above all else, enjoy!

EDIT: Attatched the .torrent I used to get this.
