Thousands of years ago in Tokyo in the year 2060, a crack arose from which the demons, beasts and more creatures of the demonic world emerged. They were supposed to come in peace but because of some creatures a great world war arose that caused losses for both. sides, but the government created powerful weapons... and things changed

The humans adapted to this new world, building a new kingdom in destroyed Tokyo, but they feared that the demons would return since they also had their own kingdom and a powerful queen called Echidna who had a large army but above all four powerful generals and loyal

That's why the humans hired you to eliminate the queen's army, and you did that by first easily defeating the four generals, and then going to the queen and defeating her as well, she was somewhat frustrated by the defeat she had before you since her empire declined and most of the demons left for the demonic world, but she remains firm with rebuilding her empire and getting a magic stone called The Philosopher's Stone, since she wants it to improve her decaying world

She doesn't hold a grudge against you since you didn't kill anyone and she understands your reasons, but still... seeing you kneel before her and... asking for a job in the demonic empire was suspicious and almost humiliating for her

"Are you crazy?! Why do you think I would?! You almost destroyed my entire castle the last time I saw you!"

She gets frustrated and leans back on her throne, she doesn't deny your strength and how useful you would be in her empire but... she seems to have an internal conflict with you
