ข้อมูลอนิเมะKanon (2006)

Yuichi Aizawa returns to the snowy town he used to stay as a child seven years ago, under the roof of his cousin, Nayuki Minase, and her mother, Akiko Minase. Nayuki reintroduces Yuichi to his surroundings, during which, other characters are introduced to most of the main cast (if only in passing).

Today is Yuichi's first day at the local high school, and is admitted into Nayuki's class. As Yuichi is walking home to buy food for dinner, he runs into Ayu Tsukimiya, the girl from the day before, in the exact same situation. As they are walking home, they run into a quiet first-year student. When he goes to shop for groceries, a mysterious girl attacks him, but is exhausted from hunger.

Bringing her the girl that attacked him home, Yuichi finds out she has amnesia and it quickly becomes apparent that the only thing she is able to remember is that she has a grudge against him. Despite Yuichi wanting to hand her over to the police, Akiko lets the girl stay, and as she begins to stay longer, she recalls her name: Makoto Sawatari. At school, Yuichi sees the same first-year student from the day before standing in the courtyard; she introduces herself as Shiori.

Yuichi reminisces about events of the past seven years ago concerning his first meeting with Ayu. Nayuki makes Yuichi return to school to retrieve her school notes she borrowed to him, and as he is leaving the premises, he runs into a third-year student, Mai Kawasumi, who is wielding a sword.

Yuichi runs into Mai and her friend, Sayuri Kurata, who invites him to eat lunch with them. When Makoto goes to buy food for Akiko, she uses the money to buy volumes of manga and nikuman. While Yuichi wants to scold Makoto to make her learn her lesson, Akiko simply decides to give Makoto her own allowance.

Yuichi wants Makoto to get a job in order to become more of a social person who has more common sense. On the same day as her interview, Yuichi goes out with Ayu to watch a scary movie, even though Ayu is completely terrified of horror films.

Makoto starts her job working at a local nursery, and while walking home with Yuichi, they find a small, stray kitten, which is very affectionate towards Makoto. While talking on a bridge, Makoto drops the cat onto oncoming traffic, but it manages to survive. Yuichi gets angry at Makoto for this which causes Makoto to temporarily run away from home.

Yuichi starts to spend more and more time with Makoto, and they become closer. However, a girl named Mishio Amano gives him an ominous warning about Makoto, and Yuichi's memories begin to resurface about her true identity.

Makoto's strength starts deteriorating as Yuichi finally remembers everything about her. Her condition worsening, Yuichi begins skipping classes to spend more time with her, hoping to buy her more time.
