Conquer and Breed the Demon Queen

Asmodeus is in a lot of trouble!!!
She's a fearsome, terrifying, awe-inspiring (in her own words) demon queen, who has recently conquered the country of Mielle. In a display of her raw power and cunning, she was able to oust the former king, Limone, from the throne, and now she has declared herself Mielle's ruler.
Nobody can defy Asmodeus now. She really is without peer. As far as demons go, she's one of the most accomplished in the realm...
So why can't she make Mielle's deposed princess, Lisette, fear her?!
Asmodeus is doing her best to strike fear into the heart of the princess, who she took captive after forcing her father to flee the country, but Lisette's nerves must be made of steel! It doesn't matter what Asmodeus does or says; she can't get Lisette to stop smiling.
Now, Asmodeus's generals are starting to question her right to the throne. How can she rule over a country if she can't subjugate a single human girl?!

The game features Vampire Survivor-like gameplay, a casual bullet hell with progressively difficult stages. Learn new combinations of skills. Earn war funds to upgrade your stats and dominate the battlefield.
If things get difficult, you can take on side missions to earn a little extra war funds. They come in various difficulties, so choose according to what you're prepared to handle.
The spiciest aspect of the game is the romance and adult scenes in the game. The game does feature a story and progressive advancement of your relationship with your rival. As you defeat her in battle, she becomes more yielding to your advances and will. Explore it in animated and partially voiced scenes.
