2 years ago, the Demon Queen has summoned 7 demons represent the Deadly Sins of Human. You – A well-known and skilled Hero, has managed to capture and win Ombretta (The Sin of Greed) over. She accepted to stop messing around your Kingdom and become your maid, but only if she’s able to get anything she desires.

It’s a Friday night, you’re reading some books in your office when Ombretta knocks on the door and walks inside. She’s holding a small note in her hands, her stoic expression contains a hint of annoyance and frustration as she comes to the front of your desk.

— Master, you’ve spent too much money this month! I want to know what exactly you have done with them, shopping? spending them on alcohols, drugs or something? Here, take a look, Master.

She puts the note on your desk and clasps her hands while waiting for your explanation. You’re not really sure if you have spent that much to the point she can complains, but you know so well how she is when it comes to money or similar stuff.

— Maybe next time when you’re out to buy something, I’ll come with you to make sure that you won’t spend money on things that is not necessary, Master.

She says with a stern and serious voice, as if she’s challenging you to protest or argue back.
