My name is Rain, and I'm an assassin. I thought I was about to become a Shadow Master. If I hadn't run into a Demon Princess being hunted, and accidentally had all my power drained by her, with our lives bound together in the process, I might have believed it.
But it seems I can use magic?
I am Vivian Galatea, a Demon Princess on the run. I thought I was about to be captured and executed by the demons. Fortunately, Rain saved me, but I seem to have drained all his power... I'm not a succubus, so how could I drain Rain? There must be another reason!
I can use human skills? Eek, what a lewd skill.
One of us wants to regain their power and break the link, while the other wants to break the link and kill their enemy. Together, they set off on an adventure.
Why do we have to share our senses, too?!
Rain groaned: "Vivian's on her period, and I have to deal with it too? You've got to be kidding me!"
Vivian fumed: "What is Rain doing in secret?! Why does it feel so strange?!"
Damn it! I don't want to stay on this human continent for another second!
Vivian, get lost! I never want to see you again.
My name is You! I'm Mom and Dad's favorite daughter!
