After the anime ends, Shiina works hard and obtains a scholarship to the prestigious Banda Academy Junior High. She then moves in with Takeo and Norio after her father's plane was attacked by dragons a second time. In an attempt to save Takeo and herself from a United States military attack on a nearby escaped dragon, a missile cuts Shiina's body in half. The following nuclear explosion completely destroys her body. Soon after, she is reborn off the shore of her grandparents' island and it is revealed that her (and Mamiko Kuri's) dragons are, in fact, the whole world. The daughter of Shiina and Takeo (conceived when Shiina has sex with Takeo after declaring her love for him, before the destruction of the world) becomes the new Eve when Mamiko destroys and recreates the planet.
Shiina and her friends usually write her given name with katakana (sometimes as シイナ and sometimes as シーナ); Shiina's mother, Misono, prefers the kanji rendering of her given name (秕), which means "a lifeless shell" or "an empty husk." Shiina's given name is romanized as Shiina in English-language versions and the Japanese graphic novels, while Kodanclub romanizes her given name as Shina
Her seiyuu is Asami Sanada.
In the anime it is not stated, but later in the manga it becomes known that Hoshimaru is Takeo Tsurumaru's dragon, not Shiina's, which explains why she could not link with the creature. When Takeo dies, Hoshimaru attempts to turn his bearer into a virgin princess, but somehow fails.
His seiyuu is Satsuki Yukino.
As a young child, Akira was very friendly and outgoing, but quickly transformed into a hopelessly shy and insecure person after being sexually abused by her father. She keeps all of her pain inside, and tries at first to free herself of that pain by slitting her wrists and later on pointing a gun to her head, but ends up unleashing her rage on her abusive father by killing him with a dagger that Komori gave her. She spends the rest of the manga in a juvenile detention center, but later is apparently released and finds Sudo, who shows her what truly happened to Komori.
In Volume 12, when Akira is seriously injured by a dragon battle (she had helped Shiina find Sudo, also pulling her out of a paralyzed state when her father dies and urging her to make peace with her mother) and sent to a local hospital, her suffering finally ends when she falls out of a window onto the street below. It is not clear whether she jumped out of the window herself or whether someone pushed her.
Her seiyuu is Mamiko Noto.
His seiyuu is Nobuo Tobita.
In the manga, the one who most often makes an appearance and saves Shiina many times over is revealed to be Misho Tamai (玉依 美笙 Tamai Mishō), Shiina's deceased sister. In the manga, Shunji (Shiina's father) discovers a different virgin princess while on a mission in Russia.
Tomonori Komori (小森 朋典 Komori Tomonori): To the outside world, Komori appears to be a kind, polite and popular boy who wants to become a doctor; in reality, however, he is a remorseless killer who wishes to change the world by sacrificing the educated in a similar manner to the Khmer Rouge's revolution in Cambodia. He tells Akira that he is going to build an everlasting empire, and that he will be king and she will be his queen. He dies at the hands of Hoshimaru after introducing immense fear into Shiina's and especially Akira's hearts. His friends and the general public do not know of his death, believing that he has simply gone missing; Shiina and Akira are the only ones who know the truth. Komori had a severely disabled mother whom he was looking after; she starves to death soon after her son's death, being unable to take care of herself. It is noted in the manga that they had no other responsible family members.
In the manga, after Komori is killed, his dragon Push Dagger begins absorbing his body in an attempt to become a virgin princess, but the two are discovered by a team of medical researchers and the half-boy-half-dragon corpse is brought to their underground laboratory and hooked up to machines in an attempt to stop the absorption. It is unknown whether or not they were successful, though it is obvious that they were at least able to slow down the process.
In the English-language Central Park Media anime, his name is Akinori Komori.
His seiyuu is Akira Ishida.
Satomi Ozawa (小沢 さとみ Ozawa Satomi): One of Komori's associates, Satomi is a haughty, stubborn girl who goes to an exclusive all-girls' school called Banda Academy. Her dragon child is a flower-shaped creature called Amapola (アマポーラ Amapōra). She fulfills a favor for Sudo by kidnapping Akira, who is believed to have a dragon. She wishes to kill people, but lacks the strength until she finally unleashes Amapola's power on soldiers on the East Fuji military training ground, creating a field of corpses. She used to have a romantic relationship with Bungo, but has become cold and distant from him since her priorities moved to the dragons.
Satomi holds a particularly strong grudge against Shiina for both killing Komori and attempting to stop her malicious plans, and often discusses with Bungo her desire to kill Shiina. When Shiina enters Banda Academy, she befriends Satomi without knowing of her evil intentions; the truth is only realised when the two visit a gallery show held by Norio and Satomi recognises one of the dolls as being based on Bungo's dragon. Later, while on a school trip, Satomi tries to kill Shiina with Amapola and succeeds in severely injuring her, including breaking her arm, but her plans are ultimately thwarted again. While she is unconscious in the aftermath, she remembers her past and how she and Bungo first came to love one another; afterwards, she becomes close to Bungo once again.
Satomi's fate at the end of the series is never determined; she is last shown screaming when Bungo dies, and then overlooking the sea while Amapola supports Bungo's corpse in a standing position. Amapola and Bungo's dragon are shown in a merged state after Mamiko destroys and recreates the world.
Her seiyuu is Kaori Tomita.
Bungo Takano (高野 文吾 Takano Bungo): A high school student and one of Komori's associates. He is usually very cheerful and carefree, though serious and supportive of his teammates in battle. He is a military fanatic with a great fondness for guns and cannons, handily supplying such weapons to his human allies when needed. His dragon is named Hainuwele (ハイヌウエレ Hainuuere) and resembles an angel with talons; in its first appearance, it attacks Shiina's father while flying a jet plane.
Though a member of his high school's track team, Bungo often skips practice to spend time with Satomi, whom he still has strong feelings for despite an apparent past break-up. He is extremely protective of Satomi, having defended her from bullies at least once when they were younger, and his usual cheerful demeanour vanishes completely when he sees her being hurt in any way. Although he and Sudo work together, he is often puzzled by Sudo's plans.
During his second attack on Shiina's father, his dragon gets sucked into Shunji Tamai's jet turbine and is crushed; Bungo himself collapses in Satomi's arms and dies soon afterwards, after experiencing extreme pain. Hainuwele and Amapola are shown in a merged state after Mamiko destroys and recreates the world. In the English-language manga, Kazuyuki Takano is his name.
His seiyuu is Hisayoshi Suganuma.
Naozumi Sudo (須藤 直角 Sudō Naozumi): One of Komori's friends, he is very calm and polite, but is in fact a dangerous sociopath who does not hesitate to commit crimes such as grand theft auto and murder to accomodate his ideals. Sudo himself claims that he has surpassed a human level of emotional discomfort and desire. He sees himself as someone who protects Earth, even though he sends Satomi Ozawa to kidnap Akira to discover whether she has a dragon. He believes he can change the world, releasing it of its bonds to tradition, custom, and common sense by means of a society based on one's abilities; he claims that only those who have an impact on the world truly deserve to live, and that the human race is wasting the limited amount of resources available to them.
Sudo's dragon resembles Hoshimaru and Ein Soph, but is significantly larger and possesses a menacing armored faceplate. Sudo never named him, but he is referred to as Trickster (トリックスター Torikkusutā) by Mamiko. It is noted that his parents and older brother are missing, and suggested in a conversation between him and one of his old teachers that he may be responsible for his family's "disappearance".
Eventually, he, Satomi, and Bungo begin their plan to destroy the world by means of a nuclear winter, but he starves himself to death whilst endlessly plotting how to select the master race of this new world he would have created. With his dying breath, he says that what he hates most of all is himself.
His seiyuu is Hideki Taizaka.
Hiroko Kaizuka (貝塚 ひろ子 Kaizuka Hiroko (manga), 貝塚 ひろこ Kaizuka Hiroko (anime)): Hiroko, nicknamed "Hiro" (ひろちゃん Hiro-chan) is an extremely intelligent girl, dragon bearer, and Shiina's friend. A group of bullies, consisting of Aki Honda, Miyoko Shito, Hiroka Takamura, and Mihaya Ozaki, torture her when she does not get low scores on exams; the manga reveals an occasion where bullies force Hiroko to ingest worms from a beaker repeatedly, and a separate occasion where the same bullies rape Hiroko with a test tube. In addition, Hiroko's parents scold her for not receiving better marks, unaware that their daughter's poor grades are the price to pay for the bullies to leave her alone. Only finding solace from Shiina, she cannot approach Shiina about the bullying, but must live with it - until the day she snaps.
After experiencing the unfairness in Japanese society, and separated from Shiina via her father's orders, Hiroko wishes that everything would disappear. This activates her shadow dragon, Oni, who proceeds to brutally kill Aki Honda (forcing worms down her throat, and using a talon to rape her and tear her abdomen open before she dies), Aki's brother with whom she has a sexual relationship (though he is only referred to as "lover" in the English manga) (smashing his head against the wall), Hiroka (throwing her off the window of their classroom), Mihaya (brutally stabbing her in a dark alley), and Hiroko's parents (stabbing them), and severely maiming Miyoko by ripping her lower leg off. Believing that Shiina would be better off without her father, she wills Oni to kill him, but Hoshimaru strangles Hiroko before she finishes the job, much to Shiina's horror. Her last words to Shiina are "You can't save everyone with kindness."
Her seiyuu is Sakura Nogawa.
Mamiko Kuri (涅 見子 Kuri Mamiko): Mamiko is a mysterious girl with cold eyes whom Sudo took under his wing when he found out she had a shadow dragon, though it is never clear how he discovered her. She does not like to wear clothing, preferring to be naked when indoors and only using a flimsy dress without any underwear while outside her home or school. She tends to be rather quiet, and often considers the people around her to be inferior, much to Satomi's chagrin when the two first meet.
Sudo eventually enrolls her at Banda Academy, the same school that Shiina and Satomi attend. She explains to Shiina late in the story that they possess the same shadow dragon, Sheol (シェオル Sheoru), and it is the earth itself. They must judge this world and make the choice of what kind of world it will become. It is also noted that she has no family, and seems to have been created by the earth to serve as Shiina's dark side.
Several gang members, who kill Norio in Volume 10 and Tsurumaru in Volume 12, rape and impregnate Mamiko in volume 11. With all of Shiina's close friends and family dead and Mamiko's tremendous power, in Volume 12 of the manga Mamiko goes berserk, destroying everyone and everything in the world (starting with the gangsters who raped her) except Shiina and herself. They begin the world over again, with Mamiko's son as the new Adam of the reborn world.
Her seiyuu is Satsuki Yukino.
Takeo Tsurumaru (鶴丸 丈夫 Tsurumaru Takeo): One of the passengers who disappeared from Shiina's plane flight, whom she confuses with the writer of a threatening note. He helps Shiina and Akira many times, although he does not always understand where his responsibilities should stand. He is quite lecherous, having five illegitimate children and three girls pregnant during the course of the series. Eventually, he impregnates Shiina too, but right before that she teaches him that there is a difference between love and procreation.
In volume 10 Takeo gets caught in a nuclear explosion while trying to escape the hellfire of U.S. soldiers attacking an escaped dragon, and later shows obvious side effects of radiation poisoning, including severe scars and complete hair loss. In volume 11 Takeo kills some of the city thugs - mostly the same ones who kidnap and murder his best friend Norio in Volume 10 and rape Mamiko in Volume 11, including the thug who tortured, raped and killed Norio. Almost at the the end of volume 12, Shiina says she loves him and they have sex, which leads to Shiina becoming pregnant.
In Volume 12 of the manga, the remaining city thugs shoot him to death in his chest at his apartment. For unexplained reasons Hoshimaru (his dragonchild, not Shiina's as many thought) cannot manage to transform him into a virgin princess. Takeo's death is the last straw that triggers Mamiko's destruction and rebuilding of the human world.
His seiyuu is Eiji Miyashita.
Norio Koga (古賀 のり夫 Koga Norio): The other missing passenger from the plane flight, as well as Takeo's roommate and friend. Norio has long hair, earrings, large eyes, and other feminine features, so many characters throughout the series mistake him for a woman, and he's nicknamed "Nori-rin" by one of the girls who mother Takeo's kids. He possesses a high-level shadow dragon named Vagina Dentata (ヴァギナデンタータ Vagina Dentāta) that often follows Takeo, and crafts new shadow dragons as a sort of hobby. Norio is very aloof and rude around other people, and it is touched on a few times that he is angry at the human race. But he actually has fierce loyalty for Takeo, comes to tolerate Shiina, and his deepest, darkest wish is to have his child.
Norio experiences a turbulent death: a gang of street punks and city thugs approaches his and Takeo's house. Norio comes outside when he hears a noise, and collapses after a blow to the stomach. The thugs drag Norio into the house and ask for Takeo's whereabouts. When Norio states that he is not there, a thug slices Norio's left ear with a sword, causing an earring to fall to the floor. Norio tries to run away, but a sword slices his achilles tendon and Norio falls to the ground. One of the thugs, after punching a fellow thug, decides that he wishes to take advantage of Norio.
After Norio is stripped and placed on a bed and a video camera is turned on, the thug rapes and stabs Norio's lower parts before giving the victim a dose of lethal injection in the neck. The other thugs vomit outside during the torture. Norio withstands the torture as bravely as he can, not screaming or crying a single tear until he receives his stab wound, since Vagina Dentata is helping Takeo and Shiina in their mission to aid Jane Franklin; when he finally dies, so does his dragon, from which a fetus develops - an expression of his love for Takeo and his secret dream to bear Takeo's child. A badly injured Takeo and Shiina's parents find Norio's severed head attached to the "body" of Norio's favorite doll; later, Takeo kills the thugs who killed Norio.
His seiyuu is Kouki Akaishi.
Her seiyuu is Satsuki Yukino.
Tatsumi Miyako (宮子 巽 Miyako Tatsumi): Tatsumi is a government agent responsible for investigating the shadow dragon case. He is one of the first to realize Shiina's significance in the dragon events, and eventually teams up with Sudo's team to try and hunt down the remaining dragon bearers. He sometimes acts very childish and feels like everything he does is right. He is also fiercely nationalistic, and often voices his opinions on Japan being the greatest and most powerful nation in the world. At the end of the series he is stabbed in the chest by a man, who, along with a mysterious woman, seems to want revenge for a wrong Miyako did to them in the past.
Her seiyuu is Chizuru Fuyuki.
Aki Sato (佐藤 明希 Satō Aki): Sato is another government agent and Tatsumi's secretary. Due to her beauty, many men at the office try to catch her attention, not knowing that she has a fiancée who is rather nervous and bumbling. Without her lover nearby, she is a cold and heartless manipulator who cares for nothing but her own power. At the end of the series, Sato stays alive until the world is reborn.
After the second incident, Aki, dressed only in a lingerie top in the manga (panties are added in the English and German versions) and a nightgown in the anime, and her brother/lover Yasuhito, sit in their house when Oni breaks through the wall. Hiroko's dragon instantly kills Yasuhito by smashing his head into a wall. After he dies, Oni forces Aki to ingest worms and then kills her. In the original Japanese manga, Oni shoves a clawed finger up Aki's vagina. The finger courses through Aki's organs and reappears through Aki's stomach. The finger then tears downward through Aki's torso; the final image of Aki shows her body cut in half. The English manga removes many of the pages in the scene and arranges the scene so that one instance of the dragon slicing through Aki's stomach is seen.
In the anime version, the torture of Aki after the worms is not clearly seen by the viewer, who only sees the shadow of Aki's body being ripped. In all versions of Shadow Star, Aki is given the fatal hit at the hands of Oni.
Her seiyuu is Kahoru Sasajima.
Miyoko Shito (市東美代子 Shitō Miyoko): A friend of Shiina, she remains always nervous when she helps bully Hiroko because she fears Shiina's potential reaction. Her lack of confidence in her own strength undoubtedly leads to her involvement in the group that bullies Hiroko. The night that the group rapes Hiro with a test tube, Miyoko is late to join them and gets beaten up by the rest of the bullies for her incompetence.
After the deaths of Aki and Mihaya, Miyoko was the first one to realize that Hiroko's bullies were the ones being targeted, and tells the teacher about the bullying and her suspicions. Hiroko's dragon Oni appears at Shiina's school and rips Miyoko's left leg off of her body; Shiina prevents the dragon from killing Miyoko, and Miyoko is taken to the hospital, where she survives (until the end of the world) but must live the rest of her life in a wheelchair.
Her seiyuu is Yuuya Yoshikawa.
Hiroka Takamura (高村宏華 Takamura Hiroka): One of the girls who bullies Hiroko. Hiroka joined their group out of jealousy for Hiroko's perfect test grades. She tries to keep the group's actions a secret at all costs, and protests when Miyoko tells the teacher about what the group had been doing. When Hiroko's dragon Oni appears at Shiina's school, it drops Hiroka out of a window in front of the whole class.
Her seiyuu is Megumi Kobayashi.
Mihaya Ozaki (尾崎三早 Ozaki Mihaya): A classmate of Shiina's and a member of the group that bullies Hiroko. She bullies Hiro along with other girls out of jealousy. Mihaya becomes the first victim of Hiroko's dragon Oni; when she is walking home alone at night after the test tube incident, Mihaya is killed by Oni in a dark alleyway.
Her seiyuu is Megumi Kojima.
Takaya Mizushima (水嶋貴也 Mizushima Takaya): He is a classmate and friend of Hiroko and Shiina. He has a crush on Shiina and has two older sisters who constantly tease him about it. He is the first one to realize Hiroko's strange behavior, but does not know that it is due to the bullying. After coming across Aki Honda and her group of bullies raping Hiroko with a test tube, he yells at the bullies to stop and drives them away. Then, Mizushima travels to Hiroko's house and tells her that he will protect her from her troubles; Hiro tells him that it is "too late," but he is not killed by Hiroko's dragon due to his kindness. Later attending a coeducational junior high school, he appears sporadically throughout the rest of the series.
His seiyuu is Hikaru Tokita.
Shoko Fukuyama (福山笙子 Fukuyama Shōko): A friend of Jyun Ezumi, and cousin and friend of Kyoji Fukuyama. Shoko is emotional and passionate, and loves Kyoji in a deep romantic way even though he is a family member. She is heartbroken when Kyoji gets in an accident and has to be hooked up to life support machines in a hospital. She and Jyun were writing letters to each other after Jyun moved away from Tokyo, but when Jyun appears at Kyoji's hospital and tells Shoko off for being selfish and weak, Shoko is hurt even more.
Shoko befriends Shiina and pours out her troubles to her at the hospital. When Kyoji dies, the following day Shoko and Shiina see his dragon and virgin princess in the sky. Shoko begins to cry and screams to him that she can be strong and go on loving him. After that, Jyun, Kyoji, and Shoko are never seen again.
Her seiyuu is Naoko Suzuki.
Ishida (石田): Ishida is a ninth grader and classmate of Akira. He has had an attraction towards Akira for a few years, and is very defensive of her. In Japanese volume 6 (English 7), Ishida helps carry Akira into the infirmary after she collapses in physical education class. Akira, who had been teased that day and desperately wanted someone to confirm her worth, briefly falls in love with Ishida in the nurse's office. She pulls him onto one of the beds, takes off her bloomers and underpants, and tries to get him to have sex with her, but he nervously declines and leaves the room. He then sits alone and berates himself for his weakness, as Akira loudly masturbates in the infirmary.
His seiyuu is Yuuki Tai.
His seiyuu is Tooru Sakura.
Jane Franklin (ジェーン・フランクリン Jēn Furankurin): Jane is an American woman and the stubborn and strong mother of a boy with cancer, Robert (ロバート Robāto), who owns a dragon, Tarasque (タラスク Tarasuku), that escaped its prison in the United States. It flies to Japan and rampages through the streets of Tokyo in volume 10. Jane meets Shiina, and though they are suspicious of each other at first, they eventually join forces along with Takeo in an effort to stop Robert's dragon. Ultimately, they manage to stop Tarask and rescue little Robert, who dies peacefully in Jane's arms.
Misho Tamai (玉依 美笙 Tamai Mishō): Misho is Shiina's deceased older sister, dead when she was attending junior high. She was cheerful and outgoing, but after the Tamai family moved she suddenly started to act much more somber and depressed.
The day Shiina was born, Misho told her then-unnamed little sister she'd get a cute name, but immediately after that asked her parents if things would be better when she died. Some days later, Misho was found dead in a puddle of her own blood; the injury was inflicted after she was dead, and her demise was filed under "unknown case". Misho's death traumatised Misono so badly that she started smoking and once even attacked little Shiina, which prompted her and Shunji's divorce.
Misho is later seen as one of the Virgin Princess (乙姫 Otohime), appearing more or less often and saving Shiina several times.
