Hokenshitsu no Kageyama-Kun保健室の影山くん; 保健室的影山君

Hiyori, a high-school student with a complex about her small stature and elementary-schooler-like appearance, managed to get an injury thanks to her friends' teasing about her unrequited love. Unexpectedly, the infirmary is not only dark, but also has an underclassman, Kageyama, rather than the nurse. Even more unexpectedly, Kageyama suddenly confesses to being a vampire, having fallen for Hiyori at first sight, and then asks her to be his *food*. How is the modest Hiyori going to deal with this stubborn and addlebrained kohai?
