Makasi is the strongest vampire hunter, but her younger brother is the weakest vampire.
She follows the rules of a human family and raises her only younger brother.
No one can stop her. She crushes every threat and denial.
Until one day, she discovers that she isn't his sister.
"So I was adopted." Makasi smiled as she closed in on the other person, watching their pitiful, pleading expression. "How interesting. You managed to keep that from me all this time."
"What a wonderful surprise."
"Now, what should you give me to repay all the years I've spent taking care of you?"
