ข้อมูลอนิเมะMonogatari Series: Second Season

It's the beginning of the second semester and on her way to the first day of school, Tsubasa has a short meeting with Mayoi who reveals that she has just came from Koyomi's house where she forgot her backpack, but could not retrieve it as he was not at home by that time. Soon after, Tsubasa has an encounter with an apparition in the form of a huge white tiger who just passes by her and upon arriving at school she tells Hitagi about it. Hitagi points out that despite Koyomi is for sure be the best person to assist her, Tsubasa did not call for his help at all, also remembering that in fact he always stood for them without the need of asking him. Some time later, Tsubasa and Hitagi watch smoke rising from afar and Tsubasa discovers that her house is on fire. With her house destroyed and no place to sleep, Tsubasa claims to her parents that she will sleep at a friend's house, but she decides to spend the night at the abandoned cram school where Oshino lived instead. Hitagi finds her there upon learning of her situation and decides to take her to her house, suspecting that the white tiger she saw might have some connection with the fire. After deciding to skip school for the next day, Hitagi and Tsubasa receive a mail from Koyomi, where he states that he must leave for a while to deal with some business of his and as they are about to take a bath together, Hitagi asks Tsubasa if she still loves Koyomi. Tsubasa instantly replies that she does.

As her parents still had not found another place to live, Tsubasa keeps staying at Hitagi's place. However, it is later revealed that the recent events had such an impact on Tsubasa that she is once again possessed by the Cursed Cat. The possessed Tsubasa sneaks away from Hitagi's house to confront the tiger she had met previously, as according to her, the fire at her house was caused by it. After a fierce confrontation with the apparition, Tsubasa returns to Hitagi's house just to find her awake and waiting for her. As Hitagi was already aware of the Cursed Cat, she was not suprised upon meeting it. In the next day, Tsubasa is back to normal with no memories of her possession like usual and for some reason, Hitagi asks her once again if she is really in love with Koyomi.

Following her question, Hitagi points out to Tsubasa that despite being similar at willing to help others, she and Koyomi are too different in everything else, including how Tsubasa is too innocent to realize if someone could approach her with malice. On the same day, Tsubasa meets Suruga at the school and learns from her that Koyomi had sent a message to her, and from the message she deduces that he wants to meet her later that night at the abandoned cram school. Upon returning to Hitagi's house, where she meets her father, Tsubasa relays to her what she learned from Suruga, and both agree to not meddle in Koyomi's affairs this time. They are later visited by Karen and Tsukihi who offer their house for Tsubasa to take shelter. Tsubasa accepts their offer, just to later learn that she must sleep on Koyomi's room. In the middle of the night, Tsubasa is possessed again and Shinobu appears before her, claiming that her connection with Koyomi was severed and she is looking for him. The possessed Tsubasa not only reveals about Koyomi's meeting with Suruga, but also offers herself to help her get there faster, but just as the two arrive at the cram school, they find the whole place burned to the ground.

Tsubasa awakens in the next day at the Araragi house and finds out that she was possessed again. As she leaves the house, she is stopped by Koyomi's mother, Mrs. Araragi. The mother explains that while having Tsubasa as a guest is no burden to them, she should not consider the Araragi family as her own. Mrs. Araragi also explains that adverting ones eyes from the truth isn't running away from the problem, mentioning Tsubasa's strained relationship with her own parents. Later, while walking through a park, Tsubasa encounters a man named 'Mr. Episode', who is a half-vampire and once almost killed her. He was also accompanied by a woman named Izuko Gaen, who Meme referred to as his senpai. Gaen claims she knows everything, but surprises Tsubasa when she shows her knowledge on Tsubasa's feelings towards Koyomi, aswell as her tiger problem. Gaen and Mr. Episode depart, after saying that Tsubasa's problem is her own, and only she can solve it. Tsubasa goes to the library to research "Kako", what Gaen called the Tiger, but finds nothing. She calls Hitagi, whom expresses her concern that Gaen named the Tiger "Kako" herself, to learn that Gaen was the maiden name of Kanbaru and her mother. Hitagi then explains that Tsubasa and the burnings are linked, as wherever Tsubasa sleeps, the place burns down soon after, which may eventually include Hitagi and Koyomi's houses. Tsubasa returns to the Araragi house, to be forced into a game of cards with Karen and Tsukihi. They discuss what the words "fire" and "flame" mean, and the sister's boyfriends. Tsubasa explains that Koyomi refuses to acknowledge the sister's boyfriends because of envy, then realizes that she is being jealous. As she prepares to confront the tiger, Tsubasa believes that she may never be able to see Koyomi again, and after attempting to leave her own mark in Koyomi's room so he remembers her, she takes a picture of herself and sends it to someone, and writes a note to her other self, in hopes that they can share each others knowledge and feelings.

In her letter to the cat spirit, Tsubasa reveals that just like her, Kako is another apparition sired by her repressed feelings, this time of jealousy and asks her to return both to her heart, as she is finally determined to shoulder all of her negative feelings no matter how it will change herself. As Kako is about to burn Hitagi's apartment, Tsubasa appears to confront it. Despite having no chance to defeat Kako, Tsubasa manages to stall it long enough to Koyomi to appear and defeat it with Heartspan. Before absorbing both the cat and tiger spirit, Tsubasa finally confesses her love for Koyomi, and as expected, he rejects her, assuming that his love for Hitagi is stronger. After her family finally rents another house for them to live, it is revealed that Tsubasa's hair developed white stripes just like a tiger, that she hides by dying them black, and she had at last asked her parents for a room just for herself, as a sign that she finally had become a true member of her own family.

On the first day of Golden Week, Koyomi Araragi, together with Tsubasa Hanekawa, buries a tailless cat that was ran over by a car. A supposedly petty and commonplace event. However, the curtain rises on the “nine days of hell" that follow.

On August 20th, Koyomi Araragi left his home to deliver to Mayoi Hachikuji something she had forgotten, and bumped into the young shikigami girl Yotsugi Ononoki. Koyomi ended up buying Yotsugi a popsicle but was unable to find Mayoi. He realized upon coming home that he had not done any of the homework that he was supposed to do, yet tomorrow was already the day of the term opening ceremony.

Realizing that he traveled to a day before Mayoi's death, Koyomi decides to save her and prevent that she becomes a ghost. While looking for directions, he and Shinobu meet a six year old Tsubasa who, suspicious of him, points them to the nearby police station where they learn Mayoi's address and return in the following day planning to guide her safely to her mother's house, but after hours of waiting, Mayoi's father appears and they learn from him that she had left home early in the morning. Koyomi manages to meet Mayoi at the same place where they first met, but after scaring her away, he saves her from being hit by a truck and his plan to prevent her death succeeds. However, after returning to the present, Koyomi realizes that his actions changed drastically the course of history as according to him, it led the world to its destruction.

Returning to the present, Koyomi and Shinobu find the whole city deserted and it does not take long for them to realize that it was a consequence of saving Mayoi's life in the past. Based on the date of the most recent newspaper they found, they come to the conclusion that something dire happened during the events of "Tsubasa Cat" and return to the shrine to look for a way to return to the past. However, they find that Oshino had put a different charm that prevents them from using its powers and when night falls they are surrounded by undead beings. After escaping, Shinobu realizes that the undead were once vampires who lost their master, and that said master must be no other than herself. According to her conclusions, when Shinobu ran away from home, it was Mayoi who helped Koyomi find her, and as she did not become a ghost in the current timeline, she had never become friends with him, thus he did not manage to find Shinobu, leading him to be killed by the Cursed Cat and Shinobu starting a worldwide vampire infection before killing herself. Looking for survivors, Koyomi and Shinobu decide to use some fireworks to bring the attention of whoever managed to escape with their lives, but it ended drawing the undead to them once more.
