Koyomi Araragi, a second year high school student at Naoetsu Private High School, befriends Tsubasa Hanekawa, the top honours student at his school. Koyomi soon realizes as he returns home that the imagery of Tsubasa's panties are still in his head, and this urges him to rush to the nearby bookstore to buy an erotic magazine for himself. Although seemingly unaffected by Tsubasa declaring her friendship with him, Koyomi eventually finds himself elated. Tsubasa instead borrows his phone and quickly gives her number and e-mail address before parting ways with him. Koyomi refuses, thinking that it will not help boost his grades. Regardless, as they return to the front gate of Naoetsu Private High School, Tsubasa attempts to bring Koyomi with her to the nearby library to study. According to him, he would experience the sadness and pain his friends would experience on the other hand, seeing the happiness and joy in his friends would only make him feel jealous, something that Tsubasa sees as a petty idea. Koyomi responds by saying that having friends decreases one's strength as a person. Tsubasa comments that for someone with no friends, Koyomi is surprisingly easy to talk to, and wonders why he does not have any. Regardless, Tsubasa shows interest in meeting one herself. Here, she warns Koyomi of rumors of a vampire with blond hair roaming across town at night, something that Koyomi does not take seriously. Despite the awkward encounter, Koyomi is accompanied by Tsubasa on their way to the nearby park, and she starts a conversation with him.

On March 25, a boy named Koyomi Araragi meets Tsubasa Hanekawa in front of Naoetsu Private High School, and their meeting is accentuated by Tsubasa's skirt being lifted by the wind in front of Koyomi's eyes.
