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

Hearing the strained voice of my mate, I grit my teeth and poured more mana into the portal, fighting hard against the operator of this Ritual Circle as I tried to overload it with my own mana, only to have to stand here for longer as they managed to match my output tit for tat.

Ever since the first portal went down, the rest of the monsters and Cultists had bunched up around the portals to defend them with their lives, and they were doing a damn good job with it too.

"Just... a few... more... moments..!"
