If it isn’t the Human Genius.

"Lady Allura." 

A green-haired, green bluish eyes, succubus walked into a certain room and bowed her head. 

"You have been summoned." 

"Alright." 

In front of her, stood a white-haired, blue-eyed girl, who had a playful smile on her face as she stood up. 

The succubus glanced at the woman in front of her and couldn't help but step back a bit. 

This human woman… 

She was… unusually intimidating. 

She does not try to be intimidating, she always has a smile on her face when she talks, and she never looks down on anyone, even the servants, but… 

She was still… strangely intimidating…

The Succubus didn't know how to approach this woman, even though she has been serving her for a year already. 

Everything goes well whenever Allura calls her and talks with her, sometimes, she even feels like she is talking to one of her best friends and just goes on and on when Allura is in front of her, 

However, whenever she has to approach her first, 

She always backs down.
