Maebara Keiichi (Seiyuu - Souichirou Hoshi) -
Keiichi is the main protagonist in the "question" arcs. The son of a famous artist, his family recently moved to Hinamizawa after an unfortunate event involving him in their hometown.
His charisma and remarkable talent for speechmaking allow him to easily make new friends and become popular in the village.
Although often affected by the paranoia, and sometimes too hasty to jump to conclusions, his inner strength and belief in his friends are one of the keys to solving the mystery.
This paranoia has different severities depending on the chapter and works in different ways.
When he needs a weapon, he uses Satoshi's old baseball bat.
Ryuuguu Rena (Seiyuu - Mai Nakahara) -
Rena is a girl who moved to Hinamizawa one year ago, and is in same grade-level as Keiichi.
She tends to end sentences with ~kana, kana as a reference to the noise that the cicadas make around the area.
She has an obsession with things she perceives as cute - generally, these things are not considered cute by others.
Every now and then, she goes treasure hunting in the town's trash heap, searching for 'cute' things to collect.
According to Mion, while Rena might look cute, people should be careful not to anger her as she becomes quite scary when angered.
When she needs a weapon, she uses a large cleaver that she found at the trash heap.
Sonozaki Mion (Seiyuu - Satsuki Yukino) -
Mion is the oldest classmate in Keiichi's class.
As the elder, she is the class president and everyone looks up to her as the leader.
Her social skills are on par with Keiichi, whom she highly respects as a friend and rival (though it is later shown that she has somewhat of a crush on him).
She acts like a tomboy, and calls herself ojisan (meaning old man), but has a hidden girlish side.
She is next in line to be the head of the Sonozaki household, which holds tremendous influence in Hinamizawa.
She is often seen with a holstered airsoft gun.
Houjou Satoko (Seiyuu - Mika Kanai) -
Satoko is a younger classmate in Keiichi's school.
She has a distinctive style of speech, ending all of her sentences with ~wa which, at times, is grammatically incorrect.
In spite of her young age, she is quite clever in setting up traps, and likes to practice on Keiichi.
Although her personality is quite energetic and mischievous during the events of the games, Satoko's past was full of trauma.
She dislikes Kabocha (Japanese Squash), and cannot tell the difference between cauliflower and broccoli.
Furude Rika (Seiyuu - Yukari Tamura) -
Rika is the main character in Minagoroshi-hen.
She is a younger classmate in Keiichi's school, and is the same grade level as Satoko.
Naturally, she is great friends with her as they live together in the same house.
She is revered by the villagers as the heir of the local shrine, and plays the role of a miko in the annual Watanagashi Festival.
She has been the head of the Furude house since her parents died, but rarely attends the town meetings due to her young age.
She uses "boku" for first-person statements, a word which is usually used only by males.
While she does not speak a lot, she likes to say nonsense words such as "mi~" and "nipa~", which inflame Rena's passion for cute things.
She also tends to end all her sentences with ~desu.
Interestingly, she occasionally shows a secondary personality whose manner of speech is much more advanced than what her age would suggest.
She also seems to have clairvoyant ability.
Despite her young age, she seems to be quite fond of sake.
Sonozaki Shion (Seiyuu - Satsuki Yukino) -
Shion is Mion's identical twin sister, who currently resides in Okinomiya.
She was sent by the Sonozaki family to a private boarding school, but escaped and returned to live near her hometown, where she lives with Kasai.
In spite of their different personalities, she and Mion often switch places, and it can be difficult to distinguish which sister is which.
Meakashi-hen is told from her point of view.
She works as a waitress at the Angel-Mort restaurant and is the manager's assistant for the Hinamizawa Fighters little league team.
She is often seen carrying a taser.
