One hundred and thirty-three years ago, Koide was transformed into a vampire when he was only sixteen. Sadly, he is now caught in an infinite cycle of repetitive homework, tedious lectures, meaningless exams, and an insatiable craving for blood. With each passing year, Koide has relived his unremarkable sophomore year of high school one hundred and thirty-three times. In his one hundred and thirty-fourth year, he feels no anticipation for any alterations, being too disinterested to do so.
Nevertheless, this year's classmates are distinct. They are excited to have a vampire among them and eager to assist him in any way feasible. Will Koide's 134th year turn out to be the one in which he breaks the curse, or is it merely a vain hope?
