Katherine Zara, a single middle aged office worker, went about her day as she always had; wake up, go to work, come home and read or play games. However, today would be different. Before she left for work, her ex broke into her apartment and killed her. 
When she woke up, she was given many choices. She could pick her new world, pick her starting point, and pick her system among many other things. And so Katherine decided to become a servant to a villainess.
Follow Katherine as she serves her petty, demanding mistress in a world of swords and magic.

Additional: The Female Lead (Katherine) will be submissive to her mistress, but will be cold towards others. I plan on having some action, but mainly this will be a story about Katherine serving her mistress and leveling up her system.

My Servant System

Upon completion of the final puzzle we were unceremoniously transported out of the trial space and into the blinding, multicolored plane that gifted us our reward, which this time wasn't something tangible like the Mana Crystals had been but instead something that changed about us.

Technically speaking the growth of our Cores was a tangible change but to me it didn't count since I wasn't going to be ripping my own Core out anytime soon to truly perceive it in it's entirety, and I was definitely not going to do that to Jahi or Leone.

The other part of the reward was actually intangible though since it accelerated our mana regeneration by an untold amount, making it easier for us to fill up our newly enhanced Core's and make use of more powerful, deadlier spells whenever and however we wanted.
