Early in the morning, the Minase family is having their breakfast, with Nayuki in zombie mode as usual. What's different is that Akiko bought out all her homemade jams on display.
And she invited Ayu to have some of her special jam. This instantly wakes Nayuki up and the two got out of the house asap.
On the way to school, the two felt sorry for Ayu that they couldn't warn her of the jam.
Nayuki then gave a present to Yuuichi. (Bunny ear) Yuuichi took it out from the paper bag and wore it, making passerby's stare on amusingly, but a not so happy Nayuki reminded him that he had asked her the other day on making a girl look cuter. Thanking Nayuki, Yuuichi was about to put the ear back into the bag when he had a flashback of...
A girl in the wheat fields wth a pair of bunny ears. As he couldn't remember the person, he shrugged it off and continued on to school.
During lunch, he went up to the usual place but only Mai was there. Sayuri had classroom duties on that day, so they had to wait a while before Sayuri can come with the lunch boxes. In the meanwhile, Yuuichi asked Mai for more information on why the monsters are attacking him but Mai said she does not know.
And he also played Shiritori, where Mai lost badly.
(Cute Mai ^_^ and Sayuri ^_^ ne!)
After school, Yuuichi managed to parry Nayuki's going home call and went to the rooftop to practice his mediocre katana skills. Mai agreed to practice with him, and Yuuichi ended up badly mauled by Mai.
However, Sayuri found the two and wanted to join too. Mai and Yuuichi warned her that they are not playing, but Sayuri was adamant.
(Yaaaaaaaa!) And Sayuri was pwned by Mai. Mai then shot Sayuri to tears by saying that she was interfering.
After his training, Yuuichi was on the way home when he met Sayuri.
Sayuri then told Yuuichi about her past; why she is close to Mai and the meaning of Kanon. They also agreed to meet at Sayuri's house to celebrate Mai's birthday and that Sayuri would call Yuuichi once she's ready.
In the evening, as Sayuri did not call Yuuichi at the stipulated time, Yuuichi decided to go to school to call Mai to go home. Telling Nayuki that he is going off to a friend's birthday party, Yuuichi went to school. 10 minutes later, Sayuri called to the Minase residence, but of course Yuuichi wasn't at home by this time.
On hearing that Yuuichi had "went to a birthday party", Sayuri decided to go to school along with the anteater plushie and her food. Halfway to the school, it then dawned on Yuuichi that if Sayuri couldnt' contact him, she may go to school to find him. He rushed to a telephone booth to call home and Akiko confirmed his worst fear.
He rushed to school, only to find a emo Mai and... ...
Mai was on the verge of a breakdown and wanted to kill herself but Yuuichi managed to persuade her off it. They decided to kill off all the monsters tonight to end this mess once and for all.
