Hinamizawa, Japan
Shion is the older (believed to be younger by everyone but the twins themselves) twin sister of the Sonozaki twins. She was sent to St. Lucia's Boarding School, but escaped in 1982 and 1983 with the help of Kasai Tatsuyoshi, a man who acts as a bodyguard to the Sonozaki family. Shion is the main villain in Meakashi-hen, which appears to be Watanagashi-hen from her perspective (though certain differing events mean the two are actually separate arcs) and shows that she was the main villain in Watanagashi-hen as well. She despised Hōjō Satoko in Meakashi-hen, blaming her for Satoshi's suffering, but in the arcs afterward, the two have a sister-like bond, and Shion even puts her life on the line to save her to keep her promise to look after Satoko while Satoshi was gone. In Matsuribayashi-hen, Rika explains that Shion's early dislike for Satoko in the years before 1983 and her learning how to control her inner demon afterward are both momentous events for Shion to avoid being a victim of the Hinamizawa Syndrome. Shion works as a waitress at the Angel Mort (エンジェルモト) restaurant and is also the manager's assistant for the Hinamizawa Fighters little league team. In truth, she was born as Sonozaki Mion, the elder sister, but due the sisters swapping places at a young age, Mion, instead of her, was branded with the oni tattoo which marks the presumptive heir to the Sonozaki family. She had to become "Shion" and her younger sister became "Mion."

When They Cry
Keiichi Maebara has just moved to the quiet little village of Hinamizawa in the summer of 1983, and quickly becomes inseparable friends with schoolmates Rena Ryuuguu, Mion Sonozaki, Satoko Houjou, and Rika Furude. However, darkness lurks underneath the seemingly idyllic life they lead. As the village prepares for its annual festival, Keiichi learns about the local legends surrounding it. To his horror, he discovers that there have been several murders and disappearances in the village in the recent years, and that they all seem to be connected to the festival and the village's patron god, Oyashiro. Keiichi tries to ask his new friends about these incidents, but they are suspiciously silent and refuse to give him the answers he needs. As more and more bizarre events occur, he wonders just what else his friends might be keeping from him, and if he can even trust them at all. When madness and paranoia begin taking root in Keiichi's heart, he will stumble straight into the mysteries at work in Higurashi no Naku Koro ni, a story that is told across multiple arcs.
