|Higurashi no Naku Koro ni Matsuri Chronology|
After helping with preparations for the Watanagashi Festival, Keiichi Maebara and Shion Sonozaki have a clandestine conversation by the river about the history of the curse of Oyashiro. The following day, the club plays a variation of Clue, which Mion loses. As punishment, she is made to run errands for the other members. While doing so, she warns Keiichi to stay away from Shion.
Keiichi and Mion meet up at the Okinomiya library. Unbeknownst to Keiichi, the girl he is meeting with is actually Shion pretending to be Mion. "Mion" reveals more details about the curse of Oyashiro as well as the fact that Jirou Tomitake has been found dead. The following day, Keiichi and Rena Ryuuguu are confronted by Kuraudo Ooishi, a detective investigating the curse of Oyashiro. Ooishi informs Keiichi of the Sonozaki family's ties to the yearly incidents, however Keiichi is skeptical. When Keiichi returns home, he finds Rena waiting for him. Rena interrogates Keiichi on his meeting with the detective and leaves when Keiichi begins lying to her. Later, Ooishi calls Keiichi's house and informs him that both Shion and Mion have been missing since Keiichi's visit to the library. Ooishi elaborates that this is the second year in a row that the twins have disappeared after the Watanagashi Festival. Keiichi is concerned by this but tries to maintain a façade of happiness so that he doesn't ruin the dynamic he has with his friends.
There are two available endings for Taraimawashi-hen. Ending A is available during the first playthrough of the arc. Ending B becomes available after completing Tsukiotoshi-hen.
- Ending A: Ten years later, Ooishi meets up with Mamoru Akasaka to visit Mion in the hospital. While the majority of the villagers in Hinamizawa fell victim to the Great Hinamizawa Disaster, Mion survived as she was locked in the basement of the Sonozaki Estate with a head injury. As a result of this injury, Mion sustained severe memory loss and is incapable of recognizing Ooishi or Akasaka. Instead, Mion attempts to play cards with them, believing them to be her friends from the club.
- Ending B: As with the first ending, Ooishi and Akasaka visit Mion in the hospital but are unable to get a response from her. Just before leaving, Ooishi places Rena's hat in front of Mion. He explains that it was found alongside the remains of a hamster inside a box in the river. The detectives leave. Mion suddenly wakes up, realizing the message Rena was trying to send with the box. She asks the nurse to bring the detectives back, declaring that there was "no disaster in Hinamizawa". The next morning, Mion dies of acute heart failure.
