The Queen Of Formations (Kai's Past Arc 9)

"So where should we begin?" Kai asked as Ayaka raised her right hand and placed it on his chest, directly over his beating heart.

"The one thing that anyone would check to see whether you are in my harem or not, is the harem mark. So for starters, I will give you the harem mark." She explained as Kai's heart skipped a beat.

A harem mark was similar to a slave mark in a sense of the word since it literally meant that one was the harem overlord's lover and could not be held by anyone else. 

So Kai was a little shocked when he heard Ayaka saying that she would give him the harem mark.

"Remove the upper half of your robes and show me your skin. I need to be directly touching it to give you the harem mark>" Ayaka ordered as Kai's narrowed his eyes.

If someone told him that Ayaka was a hidden assassin trainer, he would definitely agree with that person since she was extremely straight forward.
