OVA
Description
Oryou Sonozaki leads the Sonozaki family, one of Hinamizawa's governing Three Great Families. Her name bears the kanji for demon (鬼), reflecting her position. Estimated to be in her 70s, she appears as an elderly woman usually clad in a black kimono. Post-World War II, Oryou and her husband Souhei rebuilt Hinamizawa using wealth gained through black market dealings. This reconstruction cemented the Sonozaki family's power, though rumors about their supply sources led to external stigma. While historical claims linked the Sonozakis to incidents like the 1978 kidnapping of the Minister of Construction's grandson during the dam conflict, later revelations showed the family often claimed credit for such events to enhance their fearsome reputation, without direct involvement.

Her personality displays marked duality. Publicly, Oryou cultivates an image of sternness, particularly towards the Houjou family stemming from past dam protest conflicts. This animosity fueled the village's ostracization of the Houjous, though she never intended this hostility to reach their children. Privately, she shows consideration and kindness, such as annually preparing ohagi for a dam construction foreman's grave and arranging family land sales to attract new residents, aiming to "freshen the air" in Hinamizawa. She worries about Satoko Houjou's welfare but feels restricted by her role from showing public support. This conflict between duty and personal feeling necessitates careful maneuvering, evident when she covertly aids efforts to rescue Satoko from her abusive uncle while demanding Keiichi Maebara fabricate a story where he threatened her, preserving the family's fearsome image.

Family dynamics profoundly shape her background and actions. She disowned her daughter Akane for marrying a yakuza member against her wishes, enforcing the traditional "nail punishment" involving fingernail removal on Akane. Oryou later performed the same punishment on herself as atonement. When her twin granddaughters, Mion and Shion, were born, tradition demanded one be killed to prevent succession disputes, but Oryou avoided this. Mion was designated heir and trained for leadership, while Shion was sent away to St. Lucia Academy, fostering lasting resentment between the sisters. Despite Shion's open defiance and insults—frequently calling her "Onibaba" (Demon Hag)—Oryou permitted Shion to stay in Hinamizawa after enforcing the nail punishment following Shion's public declaration of love for Satoshi Houjou. Oryou maintained a complex relationship with Mion, whom she respected as her successor, and privately reconciled with Akane, sharing tea despite the formal disownment.

Her involvement spans multiple arcs. In *Meakashi-hen*, Shion overhears Oryou discussing the deaths of Takano and Tomitake, leading Shion to believe the Sonozakis orchestrated their murders and Satoshi's disappearance. Shion incapacitates Oryou with a stun gun, unintentionally killing her due to Oryou's frailty, and desecrates the corpse. *Minagoroshi-hen* and its *Gou/Sotsu* counterpart *Tataridamashi-hen* depict Keiichi confronting Oryou to secure support for Satoko, resulting in her clandestine assistance after private talks with Kiichirou Kimiyoshi and Akane. *Matsuribayashi-hen* explores her desire for societal change in Hinamizawa, acknowledging the need to resolve lingering Houjou resentment. She formally announces the end of the dam conflict and Oyashiro-sama's curse during the 1983 Watanagashi Festival in *Satokowashi-hen*, a scene repeated after timeline resets in *Higurashi Gou*. In *Watadamashi-hen*, a timeline variation shows Mion killing Oryou with a stun gun during an interrogation attempt and disposing of her body similarly to Shion's actions. Her final appearance is in *Kagurashi-hen*, visiting a grave alongside Akane in a peaceful timeline following Rika and Satoko's conflict.

Oryou's legacy lies in balancing the Sonozaki family's perceived authority with her underlying concern for Hinamizawa's future, navigating tradition while acknowledging the need for reconciliation beyond longstanding feuds.
