Koide was turned into a vampire at the age of sixteen--one hundred and thirty three years ago. Now, poor Koide is trapped in an eternal loop of the same old homework, the same boring lectures and meaningless tests, and an ever-unquenchable thirst for blood. Koide has repeated his uneventful sophomore year of high school one hundred and thirty-three times, and now, in his one hundred-and-thirty-fourth-year, he doesnt expect things to change and is frankly too bored to care.

But his classmates this year seem a little different than ever before. Theyre thrilled to have a vampire in their midst, and are eager to do whatever they can to help. Will 134 be Koides lucky number or is that just wishful thinking?
