Monogatari se centra en Koyomi Araragi, un estudiante de tercer año de instituto que es ahora casi humano después de haber sido vampiro por un tiempo. Un día, una compañera de clase llamada Hitagi Senjōgahara, quien nunca habla con nadie, cae desde una alta escalera en los brazos de Koyomi. Él descubre que Hitagi no pesa casi nada, una contradicción física. A pesar de ser amenazado por ella, Araragi le ofrece su ayuda, y la presenta a Meme Oshino, un hombre excéntrico de mediana edad viviendo en un edificio abandonado que le ayudó a dejar de ser un vampiro.
