Mion locks the door to the latrine. Satisfied, she feels that that should delay those trying to carry out the curse. With wild eyes, she declares that this is her chance to get Keiichi somewhere safe.
The scene pans the walk home in Hinamizawa. Concerned, Rena asks the walking Keiichi what is wrong. With Mion slightly behind him, he confesses that it is all his fault. While Rena asks, "It's your fault," Mion stares ahead. When the view centers on her face as she asks him why he thinks it is his fault, it reveals that behind her are two men in construction worker's clothes standing at the crossroads outside of a van. Keiichi starts to reply, but he is startled by the presence of the men. They turn away from them and walk towards their van. Keiichi tells Rena that it is nothing. The three pass by the men who appear to try to obscure their faces.
The higurashi c ry as the scene transitions to an arial view of the Sonozaki mansion. It focuses on one of the cameras, then the blood smeared chair that previously held Kimiyoshi. Mion, changed into her kimono, walks with Shion's body draped over her back and shoulders. Panting, she slowly makes her way to the well. She deposits Shion on the edge then pushes her over. With a view up from the well, she peers down.
The scene cuts to black with the sound of a phone ringing. Keiichi answer.png.pngs as the scene, with higurashi d oing what higurashi d o, opens in Mion's room in the Sonozaki mansion. He answer.png.pngs desperately asking if it is Shion, then changes, when Mion does not respond, to ask if it is Mion. With a wild look that When They C ry Wiki Cannot Adequately Describe™, Mion commands him to come over immediately.
The scene shifts to an arial view of the school. Police have gathered on the grounds. Satoko walks down the stairs inside and hears Chie begging the police to find Rika. She sees her bowing politely to the departing Kumagai. Chie stands straight, turns, and is surprised to see Satoko. Satoko asks her what the police said about Rika. Putting on a pleasant expression, Chie assures her that they will find her, and while she knows Satoko is worried, they will find her. For her part, Satoko looks sad and asks what she should do. Chie cheerfully encourages her to go home so she can greet Rika with a big smile when she comes back. Satoko lowers her head, which allows her bangs to obscure her eyes in shadow, as she replies that, knowing Rika, she will come back pretending that nothing happened. She looks up with a smile as she finishes. Chie relaxes in response and agrees.
A dog sniffs the grounds. The scene reveals that it is a police dog. Some distance away, Satoko voices the request that they find her as her eyes blaze. She muses that Rika going missing is the worse thing that could happen to her. With her eyes returned to normal, she turns and continues that perhaps she should ask her directly since it will be the fastest way.
At the waterwheel in her school clothes, Mion tells Keiichi that he is nervous, but she knows how he feels right now. Keiichi sweats, but his face relaxes a bit with her reassurance. However, she turns with a sad face that startles him. Her face relaxes into a smile and she invites him to talk at her home. The reflexion of the two walking towards her home is viewed in the sideview mirror of the van. The man inside reports on his radio that Sonozaki Mion has made contact with Maebara Keiichi. Ōishi replies on the radio that he is to join the detectives around the Sonozaki property and to continue his surveillance. As the two continue their walk, the detective acknowledges. Some distance away, in his car, Kumagai asks Ōishi if he believes the Sonozaki are connected to the disappearance of Kimiyoshi. Ōishi sighs and notes that Ōryo called him over, and he has been missing since.
Kumagai asks him what Ōryo has to say about this. Ōishi replies that she refuses to see them, but Mion claims he went home right after their talk. Kumagai asks if he thinks Mion is lying; Ōishi sighs again, "who knows?" Kumagai continues that if she is, then that means the mayor is still on the Sonozaki property. He then asks why they do not just barge in. Ōishi patiently replies that if they did without a good reason they might put up a fight. Kumagai grunts in concession. Smiling, Ōishi adds that if they do have a good reason, and Kumagai interrupts that that is why Ōishi has surveilled them. Ōishi laughs and replies that the moment the police hear the quietest scream they can move in.
At the entrance to the mansion, Keiichi remarks that Mion's front gate is huge. She invites him in. As he does so, one of the detectives dressed in construction worker's clothes peers around the corner of the building.
The higurashi c ry as the scene shifts to the entrance to the Furude Shrine. Satoko walks towards the home she share s d with Rika.
Inside her living room, Mion conforts Keiichi. He asks her if he can ask her a question: "why does someone have to die on the night of Watanagashi every year?" She remains silent. The scene shifts to Satoko removing a large bottle from the cabinet under the kitchen sink. She walks away with it. In the sitting room in the foreground there is a clipboard with a piece of paper in it lying on the table. The scene reveals that it is an announcement from the Sonozaki that they are delighted to share their soy sauce. It instructs the recipient to simply bring an empty bottle.
Mion stands with Keiich in the entrance to the Sonozaki underground. He asks her what the place is, but she simply silently walks in. He follows her. She places her hands on the inner door and replies that this is the safest place on the Sonozaki grounds. The scene shifts to Ōishi's car. He receives a report that there is movement in front of the Sonozaki mansion, but it is "not one of them." In response to his request for explanation, the detective informs Ōishi that they seem to have a visitor. The scene shifts back to Mion. She looks flatly at Keiichi, now behind bars, who begs her to let him help her. She looks down and asks him if he remembers the game tournament and when he gave her the doll. With a blush she looks at him and smiles as she recalls that he treated her as a girl and it made her happy. Keiichi reacts with some surprise. More seriously, she confesses that she loves him, and that is why she needs to protect him. She explains that the only way to protect him is to end this tradition once and for all.
Keiichi calmly says her name, and Mion awaits him to continue, but they are interrupted by an alarm. The scene shifts to the desk with monitors. Keiichi asks if they are here, and Mion replies that it is their minion. The monitor reveals Satoko is at the door holding the bottle. The scene, with a dramatic cord from Kawai Sensei, focuses on Satoko's face.
She grins.
Mion muses that it is interesting, and she supposes that she should say hello. Keiichi starts to ask her what she is going to do, but Mion interrupts him to tell him that she has to greet a guest. She opens a drawer and pulls out a hand gun. The scene shifts to outside her massive gate where Satoko waits. Mion opens the side door, and Satoko teases her about making her wait. Mion pretends embarrassment that she did not hear the intercom. When she asks Satoko why she is there, Satoko reminds her of her family's offer to share their soy sauce. They banter: Mion clearly does not know about this offer, and Satoko dramatically expresses her disappointment at coming to her home and not receiving the soy sauce. Mion invite her in, and a detective dressed in the construction worker clothes radios that Mion has let Satoko in. Ōishi asks him if he sees Keiichi; the detective responds that he does not from his position. Ōishi complains to Kumagai that people keep coming in but never come out. Kumagai reminds him that if Kimiyoshi is in there then what are the Sonozaki doing. Ōishi shouts into the radio a command that all should be ready to go in, then he announces that he is going in.
Keiichi slams his shoulder into the door of his cell and succeeds in breaking through. He sees the monitors that show numerous detectives dresses as workers on the grounds and communicating on their radios. Keiichi swears and then finds himself locked in by another door. He attempts to break it down as the scene shifts to black as the higurashi c ry. It resolves to a floor then an outside view of one of the houses on the compound with Mion asking who told Satoko to come. Following behind her, Satoko repeats that, as she told her, she received a notice. Irritated, Mion notes that though Rika is still missing, she came over for soy sauce. The scene reveals Satoko holding up her bottle as Mion scratches at her neck. Satoko expresses surprise that Mion has not heard that Rika came out of her hiding right after she left. The scene focuses on Mion, scratching at her neck, as she asks, "did she now?" Satoko explains that Rika hid herself to scare all of them, and she should not worry anymore.
Mion reacts by angrily scratching her neck. She demands that the smiling Satoko give her an honest answer.png.png: who told her to come? When she adds that she is done with her lies, Satoko mockingly suggests that is seems that Mion knows where Rika is. As she asks Satoko is she wants to know where Rika is, she draws her gun and points it at Satoko. Undaunted, Satoko insists that she does. Pointing her gun at Satoko's forehead, Mion insists that she first tell her who sent her, who is in charge, and who gave the order. She continues that she knows they are after Keiichi, but Satoko only replies by asking where is Rika. This shocks Mion, and Satoko continues to ask if she is still alive. Shocked, Mion declares that if Satoko is not going to answer.png.png her, as the scene shifts to her pulling the trigger.
With a view of the roof of the building, the gunshot is heard.
The bottle Satoko held falls to the ground. A gun barrel smokes. Mion looks down shocked and in pain. She holds her belly where blood is spreading. She asks "Why? How?" as she drops her own gun. She falls to the ground to reveal that Satoko is holding her own gun. She repeats her question: "where is Rika?" Mion angrily shouts "Satoko" as she reaches for her gun, but with another shot, Satoko blows away her fingers. She genially apologizes that she is quite skilled with firearms. She kicks away Mion's gun then sarcastically thanks Mion for teaching her. With a view of her bloody revolver and severed finger, Mion screams Satoko's name again, but Satoko kicks her in the face. As she explains that she wants to hear Mion's answer.png.png to her question, she presses her hot barrel into Mion's wound. Mion laughs, mocking Satoko that she is too late since Rika is already dead. She mockingly apologizes for it, but Satoko renews her inquiry. Mion screams that she strangled her like a bird, and she hopes Rika was dead, because she disposed of her in the latrine. So either Rika died from strangulation or, as Mion rather uncharitably boasts, she drowned in their own "piss and shit!"
She laugh manically, but Satoko simply seems satisfied. She deems this good. When Mion questions this responds, Satoko answer.png.png by shooting her in the head. She flatly explains that if Mion can describe Rika's death in such detail then she must have seen her to her death. She states that she will see her, "Rika," again as she places her gun to her head. Her finger snaps, and she blows her brains out. She falls, the gun lands on the floor, and the scene focuses on both her and Mion's bodies as the higurashi c ry and the scene transitions into the End Titles.
