Overview:Spring break is the time between second and third years of high school. Koyomi Araragi encounters a blood-curdling beauty. She called herself Kiss-shot Acerola-orion Heart-under-blade, an iron-blooded, hot-blooded, and cold-blooded vampire. Kiss-shot, who lost her limbs and was on the verge of death, asks Koyomi for help. After all her fear, confusion, and conflict, Koyomi gives her own blood to save her - and the next time she wakes up, Koyomi is Kiss-shot's kin. . Koyomi wishes to change back from being a vampire to a human. But for that to happen, Kiss-shot needed to fully regain her powers. With Meme Oshino, who acts as her negotiator, standing between them, Koyomi takes on three vampire extermination experts in order to retrieve her lost limbs. The last, hellish spring break of my high school life had only just begun.
