Securing a better quality of life is now the top priority. Soon, he's visited by a chance he never even thought to ask for when he comes upon a request to exorcise some evil spirits haunting a mansion. While she's normally a no-good goddess, Aqua actually seems to be an expert on exorcism so Kazuma replies immediately that he will take on this quest and rare opportunity but what's actually in store for them at this creepy estate...?!
