Synopsis

"I'm Yuki Kito. I'm a vampire. Nice to meet you." When I entered high school, there was a vampire girl in my class. I wonder how vampires manage lunch. "Well... I haven't eaten. The drinkable blood packs are in short supply..." What!? Are you okay!?

"Kito-san... can you drink my blood...?"
