My Crush is a Vampire! (Male Reader X My Monster Secret Harem!)

Hi, my name is (Y/N) (L/N), and after some pressure from my best friend Jack, well, I finally get the courage to confess to the girl of my dreams, Youko Shiragame! But well the thing is ..... SHE'S A VAMPIRE!!! I CAN'T BELIEVE THIS! The fact of the matter is, she can only keep attending High School if no one finds out about it. That's going to be a toughie, because well, she's super dense, not to mention my childhood friend Mikan picking on us! Not only that, but Jack and I learn that a bunch of our classmates are hiding things! We have an alien girl who lives inside of a robotic suit, a werewolf who changes gender, and the fact that our teacher is related to the principal of the school, who is a 1000-year-old demon!
