With a view of the Irie Clinic, Irie's voice is heard seriously declaring that not only is it not good, it is alarming. Inside, Rika reacts with surprise, and Satoko asks what is alarming. Irie matter-of-factly responds that it is Satoko's uniform. He felt that a maid outfit would better suit her. He laments that Mion would not agree. Satoko flatly celebrates the fact that she did not. Rika reminds him that they are actually there for Satoko's check-up. Brought back to reality, Irie apologizes and reminds that over the past year, Satoko's Hinamizawa Syndrome has drastically improved. Satoko credits Irie's continued presence in Hinamizawa. She happily notes that she has progressed from three shots a day to only one. Looking at the results, Irie responds that she will not need the shots anymore. To Satoko's surprised question, he affirms that her tests are negative. He declares that she is cured of the Hinamizawa Syndrome. Both Satoko and Rika react in a surprise which, if she was there, would send Rena into Cute Mode. Satoko asks if he really means that she is cured. Irie explains that he will run another set of tests, but he believe she is. Tears of happiness form in Satoko's eyes which would send Rena into Take Home Mode if she was there.
However, Rika looks at her with concern.
The block calendar shows, "Weekend, June 6, 1984."
Rika sits in the clinic's waiting room with a similar despondent look. Irie calls out to her. He triumphantly declares that the test results are unchanged. Still serious, Rika reminds him that he once said that once someone's syndrome progressed to a certain level, their symptoms could only be suppressed, and they cannot be cured. Irie responds that he did; however, it seems that the cause of the syndrome has somehow changed. He then reveals that he has seen similar improvements in every person in the village. He then adds that it started a year ago. Rika repeats as a question, "one year ago." Irie asks her if something happened then, but she shakes her head as she claims that she has no idea, then adds a "Nipaa~!" Irie laughs as he recognizes her response, then he walks away. In her Adult Voice, Rika responds to the now empty waiting room that a certain someone who spend a thousand years distrusting humans, finally opened up.
The scene shifts to a view of Hinamizawa at night. At the Sonozaki Main House, Kimiyoshi observes that they do not have many opportunities for the three heads to meet anymore. Sitting up in her bed, Ōryo suggests that people would be worrying if they knew they were meeting. Kimiyoshi turns to Rika, who dutifully sits some distance away, and asks what she wished to discuss. She responds that she has something wants them to do for her. Ōryo gently asks her to spit it out. Rika continues that when they attend the Watanagashi Festival, and the scene cuts without revealing her wish. Kimiyoshi responds that he understands her request and agrees. He turns to Ōryo and says that it is something that must be done, not just for the old people, like themselves, but for the young people as well who are their future. Ōryo looks down and calmly tells the two to go ahead. However, Rika politely insists that it will not work without her. Kimiyoshi turns towards Ōryo and says her name, but she replies that she will repeat that he and Rika may go right ahead. She then curls up to go to sleep.
At night, the paper calendar shows "Sunday, June 17, 1984."
People happily mill about the festival stall, then the taiko drums start. Rika performs her dance. At the end, she bows and receives applause from the audience. Keiichi turns to Rena and Satoko and suggests that they head down to the river. However, the taiko start again to gather everyone's attention. They look and then the audience reacts as Ōryo and Kimiyoshi join Rika on the stage. He asks for their attention for a moment. He reminds them of the Dam War. However, he continues, the scars from that war still run deep in the village. This causes Satoko to blush and look down a bit. Rika then states that it pained Oyashiro-sama to see those scars. Kimiyoshi continues that unless they change, these scars will leave a stain on the village. The older folks do not want to see this happen, and he then indicates that Ōryo agrees which generates surprised murmurs from the crowd. Therefore, Kimiyoshi concludes, he declares the Dam War over and any ties any person or group may have to the war are hereby broken. Satoko looks up in surprise. Rika continues that she is sure people have heard stories about Oyashiro-sama 's curse, particularly on those who trespass into Hinamizawa and those who choose to leave. She insists that the stories are not true. She insists that Oyashiro-sama has watched over the village for a very long time, but now he is happy and has gone back to sleep. Ōryo then speaks up to affirm that Rika speaks the will of Oyashiro-sama. She looks up and dismisses the idea of a curse. Rika repeats that there is no such thing as a curse.
The crowd appears to accept this. Ōryo calmly adds that now a new wind can lift the sails of the village.
Sunny views of the village follow with birds chirping and nary a higurashi. Rika stops walking and calls out to Satoko. Satoko asks her what she wants, and Rika states that she has a favor to ask her: "will you come shopping with me?" Satoko excitedly denies that it is a favor. She asks if Rika is heading to Seven Mart, but Rika corrects her that she is going to Okinomiya today. Confused, Satoko wonders if Rika found some good sales.
In Okinomiya, the two walk into a bookstore. There is a pan of books and magazines. Looking at a display of 1984 calendars priced half-off, Satoko comments that she cannot remember the last time Rika went to a bookstore. She then reaches out and pulls out a guide for "Five-Minute Meals," as she asks if Rika plans to buy a new cookbook. Rika walks past her and directs her to follow. She finds herself in a section for entrance exam study guides. She asks Rika whatever could she need in this section. Rika pulls out one and hands it to Satoko to Satoko's surprise. She asks Rika what it is, and Rika responds that there is something she has dreamed of doing for a very long time. Satoko looks at the book and realizes it is an exam preparation manual for St. Lucia's. She turns to Rika and starts to ask if she means, and Rika smiles, blushes, and nods. She then adds that she wants to make that dream come true with her.
Satoko appears stunned and emits a shocked, "Eh?!"
The scene cuts to black as the credits run with a new theme: Fukisokusei Entropy.
