Ketsueki_Hasu

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 eyes continued to alternate between icy and hot while my brain decided it wanted to wiggle around like an actual noodle as the effects of this 'niche power' she just taught to me showed their aftereffects.

"Uh... Gods this hurts... I guess maybe it lets you see... someone's power level or something..? Help see if they have enchanted items on them or how tattooed they might be?"

Rubbing my temples, I groaned again before sending a gentle wave of cool air across my face as I tried to get rid of my pain as best I could, and as I was soothing myself Lilith said "Technically you aren't wrong, Katherine, but there was something else I was going to say... though perhaps you've never come across one yourself..? They are rather rare..."
