Rei Miyamoto (宮本麗, Miyamoto Rei) is a second year student of Fujimi Academy, and a classmate and childhood friend of Takashi Komuro since kindergarten. She is also a protagonist of the story, next to Takashi Komuro and Saeko Busujima. Rei is a member of the Sojutsu club, and her combat skills have proven to be a strong asset to the group. She fights with a spear made from a broomstick, but, later in the story, she uses a M1A1 Rifle with a bayonet attached. She's also a member of Takashi's Group.
Rei has long, orangy-brown hair with bangs hanging over her face with two strands sticking out above the rest of her hair along with a small, single ponytail on the back of her head which leaves the rest of her hair long and reddish-brown eyes. She also has a slender figure and ample breasts. Throughout the series, she has been constantly dressed in her school uniform and has seldom changed her attire.
After they leave Rika Minami's house, Rei stops wearing the black, thigh-high socks she had on and replaces them with knee pads, in addition to elbow pads. She wears a different green skirt and removes the bow from her shirt. She also adds white fingerless gloves and combat webbing to hang her M1A1 rifle on.
While at Shizuka Marikawa's friend's house, Rei changed into her pajamas which is a tight, pink tank top and white panties.
At the Takagi Estate, Rei is shown wearing a white robe.
In an Omake chapter in the manga, Rei is seen wearing a maid outfit, an Elegant dress with earrings, a bondage dress with a whip and even a puppy costume, as suggested by other female characters.
When she was in kindergarten with Takashi Komuro, she made a pinky promise with him that, when they grow up, they will marry each other. Despite always harboring a deep affection for Takashi, his constant reluctance caused her to give up on him and date Hisashi Igou (one of Takashi's friends). Although she was dating Hisashi, she never got over Takashi and still always liked him, despite their friendship appearing totally ruined to their friends. Although Rei is supposed to be a senior along with Saeko Busujima, Rei was held back a year since her father was the police officer in charge of investigating her teacher's father. That teacher is known as Koichi Shido, who is cruel and ruthless. As some sort of revenge for having his father investigated by Rei's father, he forced her to repeat the whole year. Since then, she has held a grudge against him.
As a member of the Sojutsu Club, Rei is a headstrong and reliable member of the group. She is very caring towards everyone, especially Takashi Komuro, and is easily one of the most kind-hearted members of the group, if not the most kind-hearted. Despite her combat abilities, Rei has a generally pacifistic personality, and seems to be the only member of the group who recognizes "them" as people- during the group's fight in Taiei Shopping Town, she states that, in spite of all they've been through, she still hasn't gotten used to killing in order to survive, and she hopes she never will.
Despite her kindness, Rei isn't above tearing into her friends when she thinks they're in the wrong. An example of this is when she calls out Takashi for killing Hisashi Igou in cold blood, even saying that he did it out of resentment rather than to save her, though she wasn't thinking straight when she said it and takes it back immediately afterwards. Although constantly reprimanding Takashi for his selflessness, she admits that this was one of the reasons she originally fell in love with him, and is in fact deeply touched by his attempts to rescue Alice, as it was a reminder that they were still human beings. She is also very protective of Takashi, as shown when she stabbed Tsunoda in response to him attempting to attack Takashi.
Rei also seems to have a perverted side, as when the girls took a bath together, she groped Shizuka Marikawa's breasts to see if they were real and later did the same thing to Saeko Busujima. Rei gets extremely jealous whenever Saeko gets near Takashi and is shown to compete with Saeko for Takashi's affection, something that perplexes Saeko as it sharply contrasts her calm maturity. Rei is also implied to be highly intelligent, if not as much as Saya Takagi; according to Takashi, she's a straight-A student, which is why he couldn't understand why she had been held back.
The only person Rei seems to genuinely hate is Koichi Shido; in retribution for Tadashi Miyamoto (Rei's father) investigating the shady Shido business led by Ichirou Shido, Shido forced Rei to repeat a grade in spite of being a straight-A student. Rei's father blamed himself for the incident, and Rei has despised Shido ever since. When Shido is around, Rei displays a very dark and cold side to her completely unlike her usual kind self, to the point that she tries to convince Takashi to abandon him to be eaten by "them" and states that he would regret saving him, an instinct that ultimately turns out to be correct. However, even when Souichiro Takagi (Saya's father) gives Rei clearance to kill Shido in retribution, Rei ultimately can't bring herself to do it, having decided he isn't even worth it, a decision that earns her Souichiro's respect.
Rei has held deep affection for Takashi since they were in kindergarten and has always liked him, even promising to marry him when they were kids. However, him ignoring her after she was held back in school caused Rei to believe that he had abandoned her, hence why she left him for Hisashi. Despite getting back together with him so soon after Hisashi's death, Rei doesn't consider Takashi to be a replacement for him, and even gets angry at Takashi for suspecting as much. At the Takagi Estate, Rei admits that she never should have broken up with Takashi, that she still loves him and if he were to fall in love with another girl, she wouldn't be able to live on.
Rei is in a relationship with Hisashi Igou and has seemingly given up on hopes of being with Takashi Komuro. When the zombie apocalypse breaks out, she escapes to the rooftop of their school with them both. On the way, she is attacked by a teacher and both guys try to help her, but Hisashi is bitten as a result. At the rooftop, Hisashi dies and turns into a zombie. Despite Rei's pleas, Takashi kills him. She blames Takashi for killing him, and says that he must have liked to do so because she thought he would hate Hisashi since he was her boyfriend. After hearing such a statement, Takashi attempts to leave their barricade and go fight some zombies. Only until Rei implores him not to go and tells him that she wants him to stay with her, he changes his mind, embracing Rei in an intimate hug which seemingly rekindled their friendship/relationship. After the events on the rooftop, the two meet up with Saya Takagi, Kohta Hirano, Shizuka Marikawa and Saeko Busujima.
Later, they gather at a faculty room and plan their escape from the school. Deciding to take the school bus, the group heads toward the bus, encountering some survivors on the way and rescuing them, but they later died. After they boarded the bus, Rei spots Koichi Shido and some of his students running to their bus. She begs Shizuka and Takashi to go now, but they refuse and let Shidou and his students on. This leads to Rei becoming very displeased and she tells Takashi he will regret his decision.
Tokonosu City Streets
Now with her nemesis on the bus, Rei hastily leaves the bus with a trailing Takashi Komuro because she can't stand Koichi Shido's self-promoting speeches. After the two leave the bus, another bus crashes around them, forcing them into a tunnel to avoid the flaming wreckage. As the wreckage burns, they manage to arrange a meeting place with Saeko Busujima at the East Police Station. After walking a short distance, they encounter a zombie with a motorcycle helmet. As the zombie attacks Takashi, Rei saves him in time by striking the zombie on the head with a cement block. They later find the zombie's motorcycle and ride off in the night to get to their meeting place.
As they ride on in the night, they come across a crashed police car and salvages a pistol and some bullets. This proves to be useful later on. Later, they go to a gas station, only to find that it is self-serve and requires money to operate. Since Takashi has no money, he asks Rei if she has any, leading her to call him "the worst" which they argue about and increase tensions. Since they both realize that they don't have any cash, Takashi goes inside the store and breaks apart the cashier taking some cash, until he hears Rei scream. When he comes back, he finds Rei being held hostage by a big gangster wannabe. The man threatens to kill Rei which incites Rei to tell Takashi to rescue her, leading to the man violently groping Rei's breasts (in the anime, he also pulls down her shirt) while commenting on her body and voice. After some useless negotiation, Takashi pulls out his gun and shoots the thug at point-blank range. Rei is saved and is about to punish the man, until Takashi stops her and tells her that they have no time to deal with such scum and she notices how that the gunshot sounds attracted dozens of zombies. They left the man to his fate and then continued to ride toward their destination.
As Rei and Takashi ride away from the gas station, they witness many men in the streets slaughtering other people. Takashi remarks that it's like a battlefield, and Rei says she has never heard of any battlefield being that brutal. They try to drive past, but a few of the men notice them and one shoots at them with a shotgun, barely missing them but grazing the back of the motorcycle. Rei does not understand why they would shoot at other people, and Takashi tells her they have gone crazy "just like us". She repeats this with tears in her eyes. They ride up to a road sign which points to Tokonosu Bridge. Takashi turns sharply in the opposite direction, and, when Rei tells him the bridge is the other way, he tells her they can't go that way and to look. She looks and sees that the bridge is blocked and full of people trying to get across. They decide to head towards Onbetsu Bridge hoping they will meet the others on the way and realize they have a gun and can force out Shido if it comes to it. When they get to the bridge they are disappointed because it is also blocked, but then they see Saeko and the others who have just left the bus. Rei is particularly happy to see Shizuka Marikawa, immediately running up to hug her. When the group makes their way to Rika Minami's house, Rei helps fight off "them" who are gathered around the house.
Later, in the bathroom at Rika's house, Rei is sharing the bathtub with Shizuka Marikawa. She remarks at how huge Shizuka's breasts are and Shizuka responds arrogantly that she gets that a lot. This annoys Rei who then grabs Shizuka's breasts from behind and squeezes them firmly. She is still seen grabbing Shizuka's boobs and saying, "They're enormous!" after Takashi Komuro and Kohta Hirano find the guns. After Rei leaves the bathroom, she comes in to the bedroom to find Takashi holding Shizuka up by her butt and saying he would be enjoying it if it was for "that" reason. Rei acts jealous for a moment, but her demeanor quickly changes as she says she sees three of Takashi and falls to the floor. Takashi asks if she has been drinking, but she just says she is really tired and a lot has changed in just a day, though she is obviously a little drunk. She brings up Hisashi Igou's death and starts crying, which causes Takashi to look a little angry as he walks off to carry Shizuka down the stairs. Rei then begins calling Takashi from the stairs until he comes up to talk to her. She starts talking about how Hisashi was a nice guy and gets angry when Takashi doesn't really want to listen to her. She says he is boring and begins to criticize him, but Takashi yells at her, telling her that he is not Hisashi, Hisashi is dead, he killed him because he turned into one of "them", and she needs to face reality. Rei looks upset and starts crying again but then moves closer to Takashi and barely kisses him. Takashi turns away saying they should stop, and Rei smiles and points out that he has an erection.
They are then interrupted by the sound of a dog barking, and Takashi runs off to investigate. When Takashi says he is going to rescue the little girl, Rei wants to go with him. Takashi tells her to stay back and guard the front gate, and she starts to object, but Saeko tells her to let him go. Just before Takashi leaves she tells him to at least take the handgun and gives it to him. She then helps Saeko open the gates. While Takashi is rescuing Alice, she helps Saya load the supplies and equipment onto the Humvee.
The next morning, Rei is seen sleeping on Takashi in the Humvee while they are crossing the river. Shizuka wakes her up and she is happy when she sees Takashi but then annoyed when she notices Saeko Busujima sleeping on his lap. She rudely awakens Takashi by pinching his cheek and says that he is popular, and must be enjoying it. Takashi looks down and sees Saeko, who had been drooling, waking up. Rei looks amused as she asks Saeko what she was doing and Saeko gets embarrassed. When they reach the other side of the river, she helps Alice get changed then gets changed with the other girls.
She comes back out wearing her school uniform again and holding the Springfield M1A1 rifle. She doesn't really know how to shoot it, so Kohta puts a bayonet on it so she can use it as a spear. Rei and Takashi are later riding on the top of the Humvee, and she is very happy and points out that they haven't seen any of "them" since the previous night. However, they soon start seeing more and more of "them" when Kohta notices and ruins the fact that they might have been safe from "them" for once.
Rei notices that the closer they get to Higashi Hill's 2-chome, the more of "them" there are. Takashi and her held on tightly as the Humvee is runs into many of "them". When she sees the wires across the road ahead, she yells out to Shizuka to stop, but it is too late. The Humvee slams into the ropes smashing many of "them". The blood and guts from "them" covers the road and causes the Humvee to slide in place and the tires lock up. While Shizuka is trying to get them free, she swerves the front, causing Rei to fall off and land on her back on the pavement. She is unable to get up so Takashi jumps off to save her. They are surrounded by them, and the fight seems hopeless. Takashi hugs Rei for the last time and realizes that she has a gun. He twists it around to use it, and, because of the way it is harnessed onto her chest, Rei has severe pain in her breasts every time the gun is fired.
They are soon saved by Yuriko Takagi (Saya Takagi's mother). At the Takagi Estate, Rei is forced by Shizuka Marikawa to have ointment applied to her injury while Takashi Komuro holds her down. This is extremely painful for her and she calls Takashi a traitor. When he questions her, she says the ointment is fine but it would be better if it wasn't Shizuka. When he is still confused, she gets angry and says him shooting really hurt her tits and she will apply her own ointment from on. Later, the group decide to have a meeting in her room and she is upset that they have gather around her bed since she can't move anywhere. There is an argument among the group which leaves Takashi very angry, but Rei is able to calm him down with Alice's help.
She is next seen with the others standing around Kohta Hirano when Souichiro Takagi (Saya's father) is trying to take the guns. When the group is preparing to leave the Takagi estate, Rei walks in on Takashi practicing using his gun. He starts to talk about doubting his leadership skills and how everyone in the group is good at something except for him. Rei responds by telling him girls like guys who are cute and caring. He says he is neither of those anymore. She tells him he has always been, she would do anything to be with him, and if he ever fell in love with another girl, she wouldn't be able to go on. He doesn't understand, so she just says girls are complex. Her injuries start hurting again so she leaves and finds Saeko Busujima standing outside the door. Rei is a little angry to see and, as she walks off, Saeko asks that if "that" is true, then Rei should stop calling her senpai. Rei angrily responds that she'd rather not bring that topic up. When the group is ready to go, they gather outside the Takagi house.
While they are looking at the ATV, Rei sees Koichi Shido's bus driving in through the gate. She grabs her gun and runs to him, and, as soon as he is off the bus, she has her bayonet pressed against his face. Shido's father was a corrupt politician who was being investigated by Rei's father. To protect him and his father from getting arrested, Shido caused Rei to be held back in school one year to scare her father away from the investigation. Rei holds him accountable for holding her back and is angry that he made her father suffer. As the bayonet begins to cut into his cheek, Saya's father yells to kill him and that he would do it himself if he had a reason. Shido taunts her for a few moments, but she lowers the gun and decides not to kill him, saying he is not worth it. When Takashi tries to console her, she yells at him, but she then lightens her mood and says it's over now. After the group escapes they encounter a large number of "them" on the road. Rei is not happy that Takashi and Saeko decided to use themselves as bait so the others could get around.
Taiei Shopping Town
When Saya Takagi says that Saeko Busujima went with Takashi Komuro so they could be prepared, Rei gets a bit annoyed. The group is rejoined later at the shopping mall. Rei seems to be acting a little cold towards Saeko. After she shows Takashi the bikes and says they can use them from now on, she tells him angrily that she knows whats going on and then storms off. Takashi wonders if she is jealous about Saeko. Rei becomes very anxious to leave the mall after Shizuka Marikawa almost got raped. She questions Takashi as to when they will be leaving, saying she could be the next to get raped and that if Takashi got raped by "some bodybuilder like Hard Gay" he would understand. Saya and Saeko try telling her they need to be prepared, but she gets even angrier saying her house is only twenty minutes away. After Saeko tells her a twenty minute walk could take all night, she calms down. Soon after, she is quick to help in finding supplies.
Later, after Takashi, Kohta Hirano and Asami Nakaoka return from the clinic, Rei, Saya and Saeko are discussing how to cope in their situation. Rei wonders how they will keep the guys from snapping and becoming dangerous, and Saeko says they will have to be good companions to them and not forget she is of the female sex. As the group plans to leave the mall, they decide to got to the East Police Station and Onbetsu Elementary to find Rei's and Takashi's parents. Rei says that if they don't find them there, then they will end their search and worry about surviving. Takashi tells the others they don't have to go along with he and Rei, but they all seem happy to be in the group. They begin their escape just as "they" break into the mall.
As they are fighting their way out, Rei remarks that she hopes she never gets used to fighting like this. The group goes through the emergency exit, then Asami says she needs something and runs back in with Rei following her. They run to a fireworks shop where Asami picks up a bag of firecrackers for Alice. Rei says they should test them, but when Asami asks for a lighter, Rei yells that she's only a high school student. The group stops after escaping the mall because of Kohta being in shock from the incident in which he killed Asami. Takashi looks around and tells Rei they can't go home because they are low on ammo and would have to fight an army of "them". Rei gets upset because she is worried about her mom. After Takashi elaborates, she shows some annoyance that Hirano had to go crazy. Rei and Takashi debate until Saeko breaks them up. Rei then brings up her father. The others think it's a good plan so they set off for the East Police Station.
East Police Station
Rei is next seen as she and the others are fighting their way to the police station. They reach the station and find it abandoned. Rei begins to panic, fearing her father is dead. Takashi Komuro tries to calm her, but he is unable to. When Kohta Hirano discovers the tire tracks, she seems to calm down a little. They enter the station, and Rei points out some blood on the floor. Takashi suggests they find guns and then look for leads on Tadashi Miyamoto (Rei's father), in which Rei looks very happy at this. When they are wondering where the guns are, Rei suggests that they probably have a storeroom. They set out towards the armory, and on the way, Rei says that it's probably locked. They get to the door and Kohta asks when the station was renovated, since an older door would be easier to get through, and Rei says it was when her father transferred there, which was when she was in kindergarten. After they get the door open, an officer who has become one of "them" approaches from behind, and Rei identifies him as Officer Kato. After not finding anything, they leave the armory empty-handed, so Kohta asks where the evidence room is, and Rei says it's on the third floor and she went there when she was in middle school. As they are on the way there, they encounter more of "them", and Rei joins in the fight. They find guns and ammunition in the evidence room, and upon leaving, Saya Takagi asks Rei where the communications office is. Rei says it is the top floor, so they run for the stairs. Rei takes the lead as they fight their way up the stairs.
Rei is at the rear of the group as they enter the communications room of the police station. After they find the information about the evacuation and start running down the stairs, Saya tells the others that the evacuation is taking place at Shintoko Third Elementary School. Rei gets angry when she thinks they will go there to find Takashi's mother and forget about her parents. Saeko Busujima turns and tells her that she made a promise to be useful, and she intends to keep it. Takashi puts his hand on her shoulder and tells her that her father comes first. Rei is happy when she hears this, and she leads them down a hallway to the Public Safety Division, where she thinks her father may be. She bursts into the room and calls him, but it is deserted, and she stands and stares in disbelief. Takashi puts his hands on her shoulders to comfort her, and asks the others to help search around the room for clues. Rei goes to her fathers desk, on which there is a sign saying he is the Assistant Inspector and Chief of Public Safety and a picture of Rei standing next to a woman who appears to be her mother. When the message is revealed saying the survivors have gone to the elementary school, Rei is ecstatic and recognizes the handwriting as her father's. She runs over and hugs Takashi with tears of joy in her eyes.
Takashi tells the group that they need to go to Rei's house and try to find her mother before they go to the elementary school. When he is finished speaking and is urinated on by Zeke, he begins to doubt his leadership, so Rei tells him they couldn't have asked for anyone better to be their leader. The group exits the station and finds that it will likely begin to rain soon. Kohta suggests they go to a convenience store and get ponchos. Rei says she knows where one is, and she directs them towards it.
The group arrives at the Sevenson Station convenience store just before it starts to rain, and they begin to gather supplies. They find rain gear in a clothing store next to the station. They leave the station wearing their rain gear, and Rei is wearing a long, hooded rain coat. Rei takes the lead with Takashi as they make their way towards the neighborhood in which the two live, killing some of "them" along the way.
As they near the neighborhood, Saeko replaces Takashi and Rei in the lead, saying they may encounter neighbors or family members who have become "them." Rei then falls to the rear with Takashi. Takashi tells Saeko their only objective is Rei's mother, prompting Rei to ask about their neighbors, the Ito's, but Takashi isn't concerned about them. When the group is in danger of being surrounded by "them," Takashi leads them through a gate to a fence which is broken and has a removable section, allowing them to cut through to the house on the other side. Alice goes through to see if it is clear but falls down, resulting in Saya and Saeko going to help her. One of "them" that they are fighting is a female who Rei and Takashi recognize as Mrs. Seto. After the fight, Takashi tells Saeko she was right as neither he nor Rei could help when they recognized her. Takashi finds a clear path to Rei's house, and they set off down the street.
As they approach Rei's house, they hear someone yelling nearby. Rei recognizes the voice as her mother's. They find Kiriko Miyamoto standing outside of a barrier and yelling at the people on the other side. Rei runs up to hug her mother, and Kiriko is pleased to see her daughter. She explains how she had been living with her neighbors, and they had sent her out to get supplies but wouldn't let her back in now. Takashi invites her to accompany the group as they go to the elementary school for the evacuation. Kiriko tells the neighbors about the evacuation, but they don't believe her, even when Takashi steps in and says it's true, so they decide to leave them behind. Kohta asks Kiriko about the police uniform she is wearing, and she tells them about how she was a police officer until she met Rei's father, Tadashi. Rei asks her mother if she has heard from her father, but she only replies that she knows he wouldn't let himself be killed. Rei adds that, if he was killed, it would be to protect someone else. She asks about the weapons they are carrying, then shows them Tadashi's spear, which she took without asking. When everyone is prepared to leave, Takashi gives them orders not to run and not to shoot until he says to, then leads them down the street as a group of "them" approaches.
Rei is a member of the Sojutso club, and thus her weapons are mainly spears. At the start of the series, Rei fights with a broomstick with a broken nail at the end forming sharp edge. She then used a nightstick after losing her broomstick at the gas station. After visiting Rika's House, she upgrades to a Springfield M1A1 Super Match rifle with a Bayonet attached (she has only been seen using the bayonet and has never fired the gun) .
