Characters are arranged alphabetically by family name, and listed in Japanese format as family name first, given name second.
Rika is a part of one of the three head families that control Hinamizawa, the Furude family. They take care of the shrine honoring Oyashiro-sama, and every year Rika takes part in the Watangashi festival. Since Rika's parents died, she and Satoko live together near the shrine.
Satoko is a year younger then Keiichi and the same age as Rika. She loves setting and catching people in her traps, and is very energentic and mischievous. Satoko's parents died a few years ago, her aunt was killed the previous year, and her brother went missing, so she now lives with her friend Rika.
Keiichi is the main character of the 'Question' arcs. He recently moved to Hinamizawa and quickly made good friends with Rena, Mion, Satoko and Rika. Keiichi lives with his mother and his father, who is an artist.
Rena is a young teenage girl who loves cute things, and some would say she has strange tastes for the things she likes. She recently moved back to Hinamizawa, after having moved away a few years ago. When she moved back, she quickly made friends with Mion, Satoko, Rika and Keiichi. For some reason, Rena seems to have a strong belief that Oyashiro-sama and Oyashiro-sama's Curse exists.
Mion is a part of one of the three head families that control Hinamizawa, the Sonozaki family. She has a twin sister Shion, but since Mion is set to become the head of Sonozaki after her grandmother dies, she lives in Hinamizawa and Shion lives in Okinomiya. While Shion is quite girlish, Mion acts as the tough boyish sister. She usually carries an airsoft gun in an armpit holster, and she is also the leader of the school's games club.
Shion is Mion's twin sister. While Mion is the boyish, tough sister, Shion appears to be the shy caring one. Though they're twin sisters, Shion doesn't live with Mion and their grandmother. Instead, she went to a private school, but escaped and moved to Okinomiya.
Akasaka is the main character of the Himatsubushi arc. He is a police investigator at the Metropolitan Police Department in Tokyo and was sent to Hinamizawa on a kidnapping case.
