Despite Koyomi's warnings, Nadeko swallows the talisman and revives Kuchinawa after Shinobu berates her for once again playing the victim. The story then shifts forward to Nadeko's confrontation with Koyomi and Shinobu at the abandoned temple and it is revealed that she defeated both. Kuchinawa then reveals that he had met Nadeko when she swallowed the talisman and all their previous interactions were fruit of Nadeko's own imagination. It is also revealed that it was Ougi who had filled Nadeko about the talisman's location and that all her movements since then were a ploy to infiltrate into Koyomi's house and secure a key to break into there in secret. As Nadeko is about to kill Koyomi, she answers a call from Hitagi at his phone. Hitagi then reveals that Nadeko must kill her, Shinobu and Koyomi at this order or she may end up being killed by either Hitagi or Shinobu, and in exchange for this information, Nadeko agrees to return to kill them all at the day of their graduation. Six months later, the day of graduation is at hand, and Nadeko waits at the polar snake shrine for Koyomi, Hitagi and Shinobu who, accompanied by Suruga and Tsubasa, appear to confront her.

Nadeko awakens in the next day with Tsukihi, who had snuck into Koyomi's bed with the intention of sleeping beside him, at her side. In the occasion, Tsukihi has Nadeko confess that she always was in love with her brother and realizes that the reason why she still harbors feelings for him it is because it makes easy for her to reject all other boys who ask her out, as she believes that having a proper relationship is too bothersome. Following that, Tsukihi then grabs a pair of scissors and cuts out Nadeko's bangs, claiming that she is doing her a favour. Later at school, Nadeko's homeroom teacher keeps pressuring her to help him restore the mood along her classmates, but when she tries to ditch him out as usual, she realizes that without her bangs, her face is fully exposed, preventing her from hiding her true feelings and suddenly, she vents out her anger at him for pushing all his work on her and following that, she lashes out at her classmates for refusing to make amends with each other after the charms incident. After school, Kuchinawa reveals that Nadeko's sudden change of behavior is because his presence made her show her true feelings which she usually keeps repressed and claims that he discovered that what he wants Nadeko to seek for him is hidden in Koyomi's house. Nadeko then sneaks there and searches Koyomi's room until she finds a talisman and Kuchinawa, revealing that it is what he was looking for, asks her if she has any wish he could grant her as an act of gratitude. Nadeko then reveals that her wish is to have her feelings for Koyomi become requited, but Koyomi himself steps into the room and asserts that it is not possible.

After lying to Koyomi claiming that she was just imagining things, Nadeko decides to help Kuchinawa find his lost corpse, but they agree that she will attend school as usual, while looking for his body at night. In the next day, during school, it is revealed that Nadeko's class is still in a bad mood due to the incident with Kaiki's charms, and thus the position of class rep was somewhat forced on her. Later at night, Nadeko sneaks out of her room to start looking for Kuchinawa's body and after following a false lead, she is found by Koyomi, who takes her to his house. It is then revealed that Nadeko's parents had realized she was missing and contacted Tsukihi, who lied to them claiming that she was sleeping there, while Koyomi left to look for her. After insinuating to Nadeko that they should sleep together, Koyomi is knocked out by Shinobu who appears before her and ponders on how convenient it is for her to have such a cute and defenseless demeanor before she drags Koyomi away to have him sleep on the couch.

Fully transformed into an apparition, Nadeko confronts Shinobu and a battered Koyomi who attack with the intention of killing her, and envious of their relationship, she stabs Koyomi's heart. The story then retrocedes to some days before, in Halloween, when Nadeko, on her way to school has a short encounter with Ougi Oshino, Meme Oshino's niece, who is also a first year student Koyomi's high school. For some reason, Ougi claims that it is about time for Nadeko to stop always playing the victim before she leaves. At her school, Nadeko starts having visions of white snakes and calls Koyomi for advice, and they agree to meet at 10 PM at his house, as by that time Shinobu must be awake to provide some help. Soon after, Nadeko hears the voice of a snake instructing her to meet it at the shrine where she used to kill snakes instead and there it reveals itself as the giant apparition snake, Kuchinawa, who demands compensation for its fellow white snakes she killed by asking for a favor, to which she agrees.
