07th Expansion Wiki
This article is about a character in
Higurashi When They Cry.

Rina Mamiya (間宮 リナ Mamiya Rina) is a hostess who's dating Rena Ryuugu's father. She first appears in Tsumihoroboshi.


With her gorgeous appearance and smell of perfume, she's great at picking up men. Although she looks very shady, she seems to be involved with Rena's father.

(Translated from the official 07th Expansion website.)


Rina has pink hair and red eyes. She wears a yellow top and has a red star tattooed near the front of her hip. She also wears pink jeans. The PS2 version exchanges Rina's jeans for a blue skirt. Although it is not visible on her sprites, Rina has long fingernails.[2]


At first, Rina seems like a nice woman if a little abrasive at times and is always wearing a strong perfume. In reality, she is very crass and intimidating. She is always looking for men who might have deep pockets and manipulates them into spending it on her and swindling as much of it as she can.

Because Rina relies on intimidation so much, she doesn't seem to have any backup plans for when it fails, as seen in Tsumihoroboshi where she begs Rena to stop as she's being beaten up.


Rina was a hostess at the club Blue Mermaid and was dating Teppei Houjou, joining him in loan sharking and badger games where Rina dates other men and has Teppei accuse them of stealing his girl and then blackmailing them for money. After seeing how much Rena's dad had to spend, Rina started dating him in an attempt to claim another badger game victim.



Teppei Houjou[]

Teppei and Rina became lovers sometime after the death of the former's wife in the fourth year of Oyashiro-sama's curse and moved in together at an apartment in Okinomiya[3]. The two make money through gambling and badger games/marriage fraud scams.

Although they make gross public displays of affection, they yell vulgarities at each other a lot. Rina is also not entirely faithful to Teppei and won't hesitate to abandon him if she ever finds someone better, something she's even said in front of his face.[4]

Rena Ryuugu[]

Rina is dating Rena's father in Tsumihoroboshi, and so the two of them start to know each other better as Rina spends more and more time with her dad. Rina treats Rena kindly but doesn't do much else.

While they may appear to be on good terms, Rina's relationship towards Rena is not genuine as she's only dating her dad just to get at his money. She knows Rena doesn't approve of her, and when Rena explicitly tells her this Rina drops her kind facade and starts acting like her true, vulgar self.

In Higurashi Sotsu, Rina begins to sympathize with Rena's situation since she was also raised by a single parent and tries to break things off with her father.

Tatsuyoshi Kasai[]

Rina refers to Kasai as "General Manager" and is intimidated by him. Both work for the Sonozakis in some capacity, and Kasai is very aware of what Rina's schemes are like.

Role in the Story[]

Higurashi no Naku Koro ni Question Arcs[]


Rina's mutilated corpse is discovered at the very beginning of the chapter by some Hinamizawan villagers. The TIP "East Round Three" shows Ooishi's investigation into her murder, which reveals her real name as Ritsuko and that she worked as a hostess at the bar Blue Mermaid, which was owned by the Sonozaki family. Rina stole protection money and drugs from the place at a grand scale and was killed for it, with the police thinking there had to have been another man involved since it's rare for a single woman to get their hands on yakuza money. It's then revealed that she was Teppei's girlfriend from Okinomiya, and that her death is what caused him to return to Hinamizawa to live with Satoko.

Higurashi no Naku Koro ni Kai[]


Rina makes her first proper appearance and is introduced at Angel Mort talking to a waitress, annoyed that she can't get a seat due to the Dessert Festa. Rena sees her and they exchange pleasantries, with Rina buying some cakes for Rena and her dad. Over time Rena thinks about Rina's relationship with her dad and how Rina has been spending the night at their home more and more often and has started leaving her belongings there. Eventually their entire living room is redecorated, with Rena starting to feel unwanted.

Rena goes to a coffee shop later where she overhears Rina talking with Teppei to two other men and collecting loan money from them. She also overhears Rina's plans to swindle her father by pretending to need money to get rid of her ex-boyfriend. Rina leaves the store to cash a check, unaware that Rena was listening to her. As Rina leaves she runs into Kasai and bows to him, with the latter and Shion telling Rena about how she and Teppei do marriage fraud scams a lot. After doing some investigation, Rena remembers that Rina was planning to move into an expensive apartment in Okinomiya and discovers she had gotten her dad to pay the entire down payment for it.

Rena struggles to come up with a plan to deal with Rina, and she comes home one day where Rina and her dad say they have something to talk about. Rena dodges it by saying she has to go to the junkyard for treasure hunting with friends and runs off. Rina follows her to the junkyard to find her alone and tells her that she and her dad have been thinking about their future, and Rena flat-out says she won't allow them to get married. Faced with this cold rejection, Rina reveals she always knew Rena didn't like her with how she always ran away when she saw her. They exchange vitriol for each other when Rina suddenly claims that she's pregnant. She's Christian and so she can't abort it, and if for some reason Rena's dad breaks off the marriage then it'll cause trouble. Rena yells that she overheard Rina talking with Teppei at the shop and knows of her plans.

Knowing that they're alone at the junkyard where nobody else can hear them, Rina starts strangling Rena and attempts to kill her. She says her plan would've worked if Rena weren't snooping around and doesn't mind killing her, as Rina was going to disappear anyway after she got her dad's money. Rena grabs a piece of glass and cuts Rina's wrist with it, making her let go and yell in pain. Rena then starts beating her with a pipe, and Rina tries to escape only to fall down a mountain of junk and die from breaking her neck.

Rena kills Teppei later and makes to dispose of Rina and Teppei's corpses by chopping them up and hiding the pieces, which leads her to be found out by the club when they come to the junkyard and find the severed limbs. The club helps Rena dispose of the corpses by burying them in a forest, which Mion later moves to somewhere else using her Sonozaki influence since there was a development project to be done in that forest.


It is shown that Rena's dad was spending a lot of money on Rina when he visited the bar, which Rena discovered after checking his bank account. After conversing with Mion and then her dad, Rena had the remaining money moved to her own account and is now solely responsible for it, avoiding the tragedy that would've resulted from Rena's dad continuing to see Rina.

In the TIP "Before the Flight", Rina prepares to run away to Sapporo by plane and receives a plane ticket from one of her lackeys as they discuss a money deal. The TIP ends as soon as they see a group of cars stopping at Rina's apartment with lots of intimidating men pouring out of them. The next TIP "Wet Blanket" has Teppei returning to Hinamizawa after Rina's apparent disappearance, starting the arc's central conflict. Shion later mentions that Rina was murdered, with the police suspecting Teppei as the culprit and surrounding his house in advance.

Other Appearances[]

Miotsukushi (Omote)[]

In this alternate world set after Minagoroshi, Rika attempts to avert the situations that lead to her friends' problems. She overhears Rina and her lackeys talking at the library about their plans to steal money from the Sonozakis and informs Keiichi about it, saying that Rina will be murdered and lead to problems for Satoko if they don't do something. They tell Shion and Kasai about Rina's plans, asking them to stop her without killing her. Shion takes their concern into consideration and tells them that she overheard Rina and Teppei talking about a new badger game target, Rena's father. Rika and Keiichi then tell Rena about Rina's true colors and convince her to talk to her dad about it.

Rina's money-stealing scheme is thwarted since the locks to the Sonozaki safe were changed, meaning the keys she stole were worthless. Kasai threatens Rina non-verbally and transfers her to a different, worse-off bar. Rina's frustration grows when Rena's dad suddenly cuts off all contact with her, with a Sonozaki lawyer saying their engagement was off. Rina drunkenly walks through the village and comes across the Irie Clinic, deciding to break in and steal any money it may have.

Rina successfully sneaks into the clinic and enters the basement floor, becoming horrified when she enters a room containing human brain and spinal cord specimens in jars. Takano appears and calmly walks toward the intruder. Rina grabs a nearby gun and threatens to shoot Takano with it, but the nurse pays no heed to her and goes on about how these specimens will lead her to paradise and wisdom. Rina has no idea what she's talking about, and Takano quickly pulls out her own gun and shoots Rina in the shoulder. Rina loses consciousness as Takano tells her she's been researching a new drug and injects her with it. Rina dies with foam erupting from her mouth.

A few days later, Shion informs Keiichi that Rina's corpse has been discovered; she swears that the Sonozakis had nothing to do with it. At the Watanagashi Festival planning meeting, Rika hears some elderly villagers talking about Rina's death. She was found in a drainage canal behind some Okinomiya apartments and looked like she died from choking on mud.

Higurashi Gou and Sotsu[]


Sotsuep1 rena listens

Rena eavesdrops on Rina's conversation

Rina dates Rena's father and obtains many expensive purchases from him. Rina talks with a friend at a restaurant about her new catch having a lot of money because of his divorce, and unknown to her Rena eavesdrops on them. Rina shows interest in getting a guy to blackmail Yasunori for all of his money and Rena quickly leaves, planning to do something about Rina. However, Rina actually considers breaking things off with him since she learned he has a daughter and sympathizes since she too was raised by a single parent.

A few days later, Rina goes to the Ryuugu residence and runs into Rena there. Rina introduces herself and says she wants to be good friends with her. Rena agrees and asks Rina to come with her to the junkyard to go treasure hunting, taking her cleaver wrapped in cloth. At the junkyard, Rina steps into Rena's secret base despite her protests and tells her about how she wants to break things off with her father. She asks Rena to help too since she can convince him better, but Rena starts trying to choke her, believing she's lying. Rina hits Rena with a lamp to break free and sees her drawing her cleaver. Rina escapes the base and tries to climb a junk mountain, but she slips and falls. Rina repeatedly apologizes to Rena and asks to be spared, but Rena kills her with her cleaver. Satoko watches them from above a cliff.

Rena chops Rina's corpse into pieces and wraps them in several bags, wanting to dispose of them. She hides them in a container in the junkyard and later becomes concerned that Keiichi may have seen them. That night, Ooishi runs into Rena and interrogates her since Rina has gone missing, the last thing anybody knew being that she went to the Ryuugu residence. Rena claims that Rina left after they talked for a while, and Ooishi buys her story.


In the peaceful loop, Rena mentions that she talked to Rina to get her help when her dad started coming home drunk every night.

In the final world Rika and Satoko end up in, Rina is seen at a coffee shop drinking peacefully.

Higurashi Gou (manga) and Meguri[]


Oniaka 1-2 rena thanks rina

Rena reluctantly thanks Rina for helping her father

Rina is dating Rena's father in this world. At the junkyard, Rina speaks to Rena in private and says they plan to get married, but Rena says it's a lie since she overheard Rina talking to a guy named Tetsu (Teppei) about a golden goose. Rina gets angry, admits to her plans, and threatens to kill Rena, but Rena stands her ground and promises to protect her family. Rina starts to remember her own childhood and leaves her be.

After giving it some thought, Rina speaks to Rena again in her junkyard base and apologizes, saying she's broken up with her dad, admitted to the deception, and will pay him back everything. Rina sympathizes with Rena since she was also raised by a single parent: Rina's mom was a hostess and ran away with a customer, and her dad was always being hounded by debt collectors, so Rina grew up thinking she needed money to be happy. Rena says she won't forgive her for tricking her dad, but she does thank her for making him happy.
