My Yandere Vampire Little Sister and My Cross-Dressing, Story-Obsessed Older Brother

"Become my kin, my other half, and live on, big brother."

Not only have I become a vampire girl's kin, I also have to cross-dress and attend the girls' division of her school with her?! But wait, isn't going to school with a vampire an amazing thing...? I'm not talking about the cross-dressing!

Can a cross-dressing boy, immersed in stories, really have a fateful encounter with tales of monsters?

If you yearn for a "story," perhaps you'll find your answer here.
