It's called Queen of Massacre, I remember when GuroPrince found an unofficial version of this on an obscure japanese site with many other games unreleased on dlsite. Sadly I can't remember it,
However this particular game is now on ci-en, developing nicely.
Here is the creator's page

And the only download link I could find there

I'm also interested of unreleased or newer versions of this so if you find them please post. Sharing is carring!:)
