You have a sister named Juri. She is soft and innocent, and she will sweetly call you Onasan-sama.
In this way... I want to become one with her and be with her forever.
But... The vampires in this world are actually family marriages.
You can't stand this outcome, you can't stand having your lovely Juri taken away.
So...
"Juri wants to be with me."
"Otherwise, I don't know what will happen if I step into a crazy monster..."
Intention: My love for you is as separate as flesh and bone
