Raul Chaser wants to be the Hero famed for defeating the Demon Lord - at least, that used to be his dream, until another warrior beat him to the punch! With peace now restored and all Heroes out of commission, Raul reluctantly gets a job at Leon, a small store that sells magical commodities. Compared to slaying demons, Raul’s new life of greeting customers and working the register is uneventful at best - that is, until Fino Bloodstone, the Demon Lord’s busty daughter, is suddenly hired at the stop! Raul now faces a challenge more difficult than vanquishing her father: teaching the clumsy and ill-mannered Fino how to become a respectable employee, while simultaneously fending off tentacle monsters and putting up with pervy regulars’ skirt-flipping antics!

Year 20XX, strange phenomena started to occur all around Japan. The best way to explain it would be a ''hole'' that connects different worlds to our world. Many otherworldly beings - magicians, demons, robots and other fantasy creatures started to appear on this side, with no way to return. With the time passing, Japan was able to adapt to this event and visitors from another world stopped to be anything unusual. And so, an unlucky witch named Henrietta was pulled through the ''hole'' and ended in modern day Japan without a way to return. How will she be able to live in this different world?
