One day, a vampire fell onto the balcony of my room.
She was strong, proud, and incredibly beautiful, she awoke and tried to kill me... but was defeated by a cross made of disposable chopsticks.

That's right, vampires have a ton of weaknesses!!!

"I hate crosses!" "You don't hate them, you're going to overcome them, right?!"
Thus begins the days of training between me, Nogami Takushi, who offered to help her overcome her weaknesses, and the strongest vampire, Lady Adelheid—training that somehow always ends up being a little naughty!

A thrilling and intense romantic comedy that will captivate innocent boys. ♡
