Description
Kuraudo Ōishi is a detective at Okinomiya Police Station, consumed by his investigation into annual deaths in Hinamizawa during the Watanagashi Festival. He relentlessly pursues the Sonozaki family, convinced they orchestrate these incidents, a fixation that escalates as his retirement nears. Born November 15, 1923, in Okinomiya, he lost his estranged biological father in a WWII Nagoya bombing raid. Postwar, while enforcing black market rules, he met a surrogate father figure who managed the Hinamizawa Dam Project. When this man was lynched during labor unrest, Ōishi blamed the Sonozaki family’s anti-dam activities, fueling his obsession.
Physically, Ōishi appears as a muscular but overweight elderly man with short grey hair and green eyes. He chain-smokes "Gaster" cigarettes and wears a black collared shirt, red tie, red suspenders, and yellow pants, often carrying a cream suit jacket. He sports dark brown shoes and a watch on his left wrist.
Beneath an affable, playful exterior, Ōishi employs ruthless tactics: intimidation, violence (like restraining Keiichi Maebara), and manipulation (exploiting Keiichi’s outsider status for intel). Villagers dub him "Oyashiro-sama’s messenger," noting his interviewees often die soon after. Paradoxically, while he suspects the village of conspiracy, locals view him as the curse’s architect.
His relationships reflect this tension. He maintains a volatile alliance with Keiichi across multiple arcs and harbors open hostility toward the Sonozaki family—especially Mion—though they pragmatically cooperate, as during Rena Ryūgū’s search. He later reconciles with Akane Sonozaki, even playing mahjong with her. Professionally, he collaborates with subordinate Katsuya Kumagai and ally Mamoru Akasaka, rescuing a kidnapping victim in 1978 and co-authoring "Higurashi no Naku Koro ni" to document the Great Hinamizawa Disaster.
Ōishi’s investigations drive pivotal events. In *Onikakushi-hen*, he questions Keiichi about Tomitake’s death, revealing Rena’s institutionalization and the Sonozaki family’s alleged role, worsening Keiichi’s paranoia. During *Watanagashi-hen*, he admits to using Keiichi as bait to raid the Sonozaki estate. In *Tatarigoroshi-hen*, he harasses Satoko Hōjō and assaults Keiichi. *Himatsubushi-hen* details his 1978 kidnapping case with Akasaka, showcasing his mahjong skill and ballroom dancing hobby—a passion he dreams of teaching professionally.
Post-retirement, he relocates with his elderly mother, commonly to Sapporo, yet remains haunted by Hinamizawa’s mysteries. When afflicted by Hinamizawa Syndrome in arcs like *Tataridamashi-hen*, he commits violence against villagers, including Shion, Mion, and Satoko.
Trivia notes highlight his wrestling prowess, fearlessness (except toward the dam manager), fan nicknames like "Detective Delicious" (a pun on "Ōishi") and "Cloud" (from "Kuraudo"), and his claim of firearm expertise despite minimal experience.
