This eventually drives him to murder Rena and Mion, who w were trying to help him, and he dies from clawing his own neck inside a phone booth. Despite this, the inner strength and unshakable belief in his friends he acquires in the later arcs end up being a key detail in the series' resolution. Eventually, he is even able to recall some of the events of the past repetitions. Before fighting, he wields Satoshi's old baseball bat. His family's reason for moving to Hinamizawa is revealed in Tsumihoroboshi-hen: he grew weary of school, and was ostracized because he thought differently than the other children; to cope with his immense stress, he begins to shoot children with a BB gun, becoming increasingly aggressive with these crimes until he accidentally shoots a young girl in an eye. Immediately following this incident, Keiichi reveals his crimes to his parents and he and his family move to Hinamizawa to have a "fresh start".

Played by: Aika (film), Hinata Honma (TV series)

One of Keiichi's friends and the main protagonist of both the fourth and final "question" arc and all the "answer" arcs, as well as the ultimately true main protagonist of the entire series. She is in the same grade level as Satoko and they live together in the same house. She is revered by the villagers as the heir of the local shrine and as the "reincarnation of Oyashiro-sama", and plays the role of a miko in the annual Watanagashi Festival. She becomes the head of her house, surpassing her parents, but rarely attends town meetings at a young age. She often likes to say nonsense words such as mii (みぃ〜) and nipah (にぱ〜) and also likes to end her sentences with nano desu (〜なのです, lit. "it is so"); these inflame Rena's passion for cute things. She also likes to describe events using onomatopoeia, such as "The cat was going 'nya nya' and 'scritch scritch'" or saying "Clap! Clap! Clap!" when clapping her hands. In contrast to her surface personality, Rika (and Hanyū) are time loopers, who have been repeating events of the series for around a century by the time of Minagoroshi-hen. Her ultimate goal is to continue looping through time until she discovers a way to get past her seemingly guaranteed death as part of "the curse of June 1983". In most of the worlds, she and Hanyū are the only ones to remember the previous timelines. She believes she has lived over 100 years by the time of Tsumihoroboshi-hen, but continues to act like a child in order not to alarm her friends. Prior to Matsuribayashi-hen, she befriends Hanyū beyond her imagination. Despite her young age, she sometimes drinks wine and eats kimchi as a coping mechanism, much to the chagrin of Hanyū. It is later revealed that the reason for Rika's consistent deaths is Takano Miyo's belief that her death would cause mass hysteria among all those afflicted with Hinamizawa Syndrome.

She is distinguished by her obsession with things she perceives as adorable, calling them kāii (かぁいい, a slurred form of kawaii (かわいい), meaning "cute"), which are usually moekko characters or items she finds while scouring the local dump. Whenever she sees something that grabs her attention, she proclaims "I'm gonna take it home!" (お持ち帰り〜, Omochikaerī) and proceeds to try and do so, becoming virtually unstoppable during these intervals. She also utters the phrase haū (はぅ〜) when excited or flustered, and has a habit of repeating phrases at the ends of her sentences, most famously kana? kana? (かな? かな?, lit. "I wonder, I wonder?"). She was born and raised in Hinamizawa under her real name, Reina (礼奈), which she used until her parents' divorce. Her family moved to Ibaraki Prefecture because of her mother's career, where she resides until a year before the events of the story. It's revealed in Tsumihoroboshi-hen that she lives with her father and remains bitter and resentful towards her mother because she had an affair and left her father. Rena blames herself for trusting her mother and the man her mother had an affair with, and this guilt causes Rena to have a mental breakdown, where she breaks many windows and assaults three male students at her school. She also attempts to slit both her wrists under the influence of Hinamizawa Syndrome. Believing herself to be cursed by Oyashiro for leaving Hinamizawa, Rena and her father returned to the village after the incident, and she changes her name to "Rena" because the letter 'i' in Reina represents 'icky' things that she swore not to remind her of. As not to alarm Keiichi about her past, Rena claims to be a relative newcomer of the village. Due to the incident, Rena is sensitive about the topic of Oyashiro, believing strongly in the existence of the deity and the curse, and becoming angry and unstable whenever anyone questions it. She wields a large machete borrowed from her tool shed.

One of Keiichi's friends, Mion is Shion's identical twin sister and the leader of the after-school club. Her social skills are on par with Keiichi, whom she highly respects as a friend and rival (though it is later shown that she is in love with him). She acts like a tomboy, and calls herself oji-san (meaning old man), but has a hidden girlish side. She is next in line to be the head of the Sonozaki household, one of the Three Families of Hinamizawa, whom hold tremendous influence. She is often seen with a holstered airsoft gun in the original visual novel and anime, even though she does not use it (this was removed in the PS2 adaption of the game). She has also received military training, consisting of leadership instruction, martial arts, helicopter piloting, and radio operating, as shown in Minagoroshi-hen. As a result of her upbringing and training, she is an exceptional leader, being able to best the paramilitary force of the Mountain Dogs through the use of guerrilla warfare. She is notable as the only character that has never been driven to the extreme paranoia that causes the others to kill in the question arcs and the first two answer arcs. Her real name is actually Shion, as she was born second to the family, but the two sisters choose to swap places during their childhood to experience each other's different side of life. Due to this swap, she ended up being mistakenly "becoming" Mion and she is branded with the oni tattoo, ultimately causing her to live as Mion permanently. She organizes a variety of strategy-based games for the members to play, with penalties for any losers. Penalties usually involve wearing embarrassing or frilly outfits on the way home. Each game she organizes involves bending the general rules, or using questionable and crude methods to win, such as using marked playing cards or using feminine wiles to discourage opposition.

Played by: Rin Asuka (film), Rika Nakai (TV series)

Mion's identical twin sister living in Okinomiya. In spite of their externally different personalities, her and Mion often switch places and it can be difficult to distinguish between them. It is noted by Rena that, although externally the twins are very different on the inside, they are really the same. Their first switch took place when they were little. Right before tattooing the symbol of a demon, the sisters swapped their roles together to live their own lifes as one another with the real Mion becoming Shion while the real Shion became Mion who later has her entire back tattooed to denote her as the Sonozaki heir which was only mentioned in the sound novel and manga. A year before the storyline shown in Meakashi chapter, Shion abandons St. Lucia Academy that her grandmother, Oryu sent her to as she strongly dislikes her own boarding school and returns to the village. In spite of it, she and Mion maintain a close relationship and helped each other. She later meets Satoshi who she develops an instant liking to him after he rescue her from the delinquents after accidentally angering them. In most of the arcs, she is at a different school from the other characters, and therefore appears less frequently. Shion blames the Three Families for Satoshi's disappearance in Watanagashi-hen and Meakashi-hen (the latter told from her point of view). In the sound novel, manga and anime, when Oryu became aware of Shion living in Okinomiya and exposing her true identity, she was summoned to the main house and forced to perform a "Distinction of Right and Wrong," a ritual of self-mutilation to pluck out three fingernails in front of witnesses in order to purge her 'sins'; first with Kasai, her close bodyguard for assisting her to escape the school, second with Yoshirou, one of her uncles who's also her employer for the Angel Mort and third with Satoshi because she was interacting with a family member of the Hōjōs whom the villagers despise for supporting the dam construction in Hinamizawa. Believing that doing so will cause Satoshi to be spared, an event personally overseen by Mion, which drastically strains their relationship. This, along with a demonic alter-ego she manifested in her grief, eventually drives her to mass murder, which led her previously latent paranoid schizophrenia to eventually develop into a full-on psychosis. One of the last words that they exchanged before he disappeared was a promise to take care of Satoko. In Watanagashi-hen and, more explicitly, Meakashi-hen, her resentment toward Satoko for her role in his disappearance causes her to forget this promise and murder her in cold blood. In Meakashi-hen, she inadvertently blames her family and friends for Satoshi's disappearance. But in Minagoroshi-hen, Upon remembering Satoshi's promises in this world.

In Matsuribayashi-hen, Irie learns that Satoko accidentally shoved her parents from the cliff to their deaths below the river. Satoko suffers with the syndrome at that time and though Takano wanted to dissect her alive for study, Irie fought to save her life. She is one of the few characters to ever recover from the fifth level, but has to take shots on a regular basis. Though she greatly misses Satoshi, and feels that by being strong he will return, she comes to regard Keiichi as her new "nii-nii" (にーにー, a cute term for "older brother"), and once even regards Shion as "nee-nee" (ねーねー, a cute term for "older sister").

Hanyū (羽入, Hanyū)

Voiced by: Yui Horie (Japanese); Xanthe Huynh (2020 anime) (English)^[3]

Hanyū is the true identity of "Oyashiro-sama". Though her existence as Hanyū is only explicitly revealed in Minagoroshi-hen, her identity and true nature (as opposed to the superstitions surrounding Oyashiro-sama) is hinted at throughout the series. Until Matsuribayashi-hen, she cannot be seen or interacted with by any of the characters besides Furude Rika, for whom she serves as a close friend. The mysterious "transfer student" in Matsuribayashi-hen. She has a pair of dark-colored horns on her head, one of which is chipped slightly. In the original sound novels, they are mentioned by Keiichi, who mistook them for toys, but after noticing that Hanyū was sensitive about them, he apologizes and the club members assure her there is nothing wrong with them. However in the anime, nobody notices or mentions them, except Takano calling her a "monster". She has appeared to Rika all her life, but only in Matsuribayashi-hen and Miotsukushi-hen did she gain the power to interact with others, posing as a distant relative of Rika's and given the name "Hanyū Furude." Like many of the characters, she can be frightening when angered, and with her spirit-like nature, her appearance can change with her mood until she takes a physical form. She is the one responsible for the eternally repeating June 1983, which she created in order to save Rika. She is also responsible for the "extra footstep you hear after you stop walking," "feeling of being watched as you sleep," and hearing "I'm sorry" when no one is around or says it, which amplifies the characters' paranoia. She follows around the characters, repeatedly apologizing for not being able to change their fate. She is very meek and often makes the noise "Au au, au au…" when she is nervous or uncomfortable, or sometimes while trying to make a point. She tends to end her sentences with nano desu (なのです, lit. "it is so"). She dislikes alcohol and kimchi, which Rika threatens her with as punishment when she finds Hanyū annoying (as Hanyū and Rika's senses are linked together until Hanyū takes physical form). She mentions that she is a "being above humans" after being sacrificed to atone for the sin of humans, while both Rika and Takano describe her as a kind of deity. Rika refers to her as "Oyashiro" when talking with others (evident from Shion's chat with Rika in Meakashi-hen) but does not personally think of her as Oyashiro. In Higurashi no Naku Koro ni Rei, Hanyū tells Rika that she was sacrificed to atone for the sins of the people of the village, and Hanyū asked Ōka Furude (古手 桜花, Furude Ōka) (Hanyū's own daughter and Rika's ancestor, who appears physically almost identical to Rika) to kill her and then make the village a better place. In the DS-exclusive arc, Kotohogushi-hen, it was revealed that Hanyū's real name was Hainiryuun Ieasomuuru Jieda (ハイ=リューン・イェアソムール・ジェダ), and that she had a child, Ōka, with the Shinto Priest Riku whom she rescued him as a baby in a house fire.

Satoko calls him nii-nii, a childish form of the Japanese word ani (兄, meaning older brother). It is later revealed that he had been taking the brunt of the siblings' uncle and aunt's physical and emotional abuse, often stepping in to save Satoko from suffering.
