大石 蔵人

Ōishi will stop at nothing to solve the serial murders, and believes the entire village to be in on it, with the Sonozaki family at the center. Due to this, he is hated by most of the village, particularly Mion, who firmly believes in her family's innocence. 

Even though Ōishi suspects the entire village as the culprits, ironically, the villagers themselves suspect that he could be the culprit, even going as far as calling him "Oyashiro-sama's messenger". This is due to fact that Ōishi happened to come in contact with each of the victims of the curse shortly before their deaths, leading the villagers to believe that he chose them./
