Parasyte (Japanese: 寄生獣 Hepburn: Kiseijū?, lit. "Parasitic Beasts") is a science fiction horror manga series written and illustrated by Hitoshi Iwaaki, and published in Kodansha's Afternoon magazine from 1988 to 1995. The manga was published in North America by first Tokyopop, then Del Rey, and finally Kodansha Comics USA. The manga has been adapted into two live-action films in Japan in 2014 and 2015. An anime television series adaptation by Madhouse, titled Parasyte -the maxim- (寄生獣 セイの格率 Kiseijū Sei no Kakuritsu?), aired in Japan between October 2014 and March 2015.[3]


A manga panel showing a parasite about to attack a human being.

Parasyte centers on a 17-year-old male named Shinichi Izumi, who lives with his mother and father in a quiet neighborhood in Tokyo. One night, worm-like creatures called Parasites appear on Earth, taking over the brains of human hosts by entering through their ears or noses. One Parasite attempts to crawl into Shinichi's ear while he sleeps, but fails as Shinichi is wearing headphones, and enters his body by burrowing into his arm instead. In the Japanese version, it takes over his right hand and is named Migi (ミギー?), after the Japanese word for 'right'; Tokyopop's version, in which the images are flipped horizontally, has the Parasite take over Shinichi's left hand and it is named Lefty.

Because Shinichi was able to prevent Migi from travelling further up into his brain, both beings retain their separate intellect and personality. As the duo encounter other Parasites, they capitalize on their strange situation and gradually form a strong bond, working together to survive. This gives them an edge in battling other Parasites who frequently attack the pair upon realization that Shinichi's human brain is still intact. Shinichi feels compelled to fight other Parasites, who devour humans as food, while enlisting Migi's help.


Main characters[edit]

Shinichi Izumi (泉 新一 Izumi Shin'ichi)
Voiced by: Nobunaga Shimazaki (Japanese), Adam Gibbs[4] (English)
Shinichi is the protagonist of the manga, a thoughtful, compassionate high-school boy whose hand is infected with a Parasite. Shinichi is repeatedly put into difficult positions. He must find a way to peacefully coexist with Migi, the Parasite which has taken over his hand, and reconcile his desire to protect humanity from the Parasites with his desire to keep his own Parasite a secret in order to avoid being killed or used as a laboratory specimen. Like a superhero with a secret identity, he must also find a way to explain away his Parasite-fighting activities, as well as the stress and grief they cause him, to his friends and family. Shinichi's retention of a human mind, emotion, and sensibilities causes other Parasites to see him as a threat. He and his Parasite must defend themselves from attacks by other Parasites, and their ability to think and act independently, and as a team, gives them a tactical edge over normal Parasites.
Masanori Harada, a 20-year-old student, wrote to the editor of the Monthly Afternoon noted that Shinichi acts calm when he is threatened and that he is "not human anymore!" Iwaaki responded, stating that Shinichi is accustomed to "close calls" partly because Migi calms Shinichi down during battle. The statement and response were printed in the April 1993 Afternoon.[5]
Shinichi is portrayed by Shota Sometani in the film.
Migi (ミギー Migī, also called "Righty")
Voiced by: Aya Hirano (voice), Rinka (sound effect)[6] (Japanese), Brittney Karbowski[4] (English)
Migi is the Parasite which lives in Shinichi's right hand, named after the Japanese word for "right" ( migi?). Unlike "successful" Parasites, Migi has no desire to kill humans for sustenance, and is nourished by the food Shinichi eats. Migi is, like other Parasites, completely without emotion. His primary consideration is survival, and he has threatened (and in some cases attempted) to kill other humans who pose a threat to his and Shinichi's secrecy. When he and Shinichi were first coming to terms, he even threatened to remove Shinichi's other limbs in order to render him unable to place the two of them in danger. Migi can be reasoned with, however, and has just as much reason to be mistrustful of other Parasites as does Shinichi. On the other hand, unlike Shinichi, Migi has no inclination to place himself at risk in order to protect other humans from Parasites. As the series goes along however, he becomes more human, whereas the reverse happens to Shinichi.
Iwaaki explained that while Migi appears to be Shinichi's weapon, in fact Migi is in control of the battle and orders around Shinichi. Iwaaki explained that Migi is easily able to order Shinichi since Shinichi is young and "needs guidance", while Migi would find difficulty if he became a part of a politician or a president of a company since in that scenario Migi and his host would argue a lot.[5]
An 18-year-old from Saitama Prefecture named "Midari" asked in the letters to the editor that if Migi took Shinichi's left hand, if he would have been named "Hidari". Iwaaki answered that it would be Hidari, but Iwaaki felt that the name would be similar to those of Bokuzen Hidari or Tenpei Hidari and the name would "bring to mind a doddering old man, so that wouldn't have been a good idea". Iwaaki then said that the first man to climb Mount Everest "had a name an awful lot like that..."[7]
Migi is voiced by Sadao Abe in the film.


Satomi Murano (村野 里美 Murano Satomi)
Voiced by: Kana Hanazawa (Japanese), Luci Christian[4] (English)
Shinichi's best friend and sometime companion. Shinichi and Satomi develop a romantic relationship over the course of the series, but their attraction to and fondness for one another is hampered by Shinichi's fear of his own monstrous nature, and Satomi's fear of Shinichi's secretive behavior and the mood swings that result from the trials and tribulations in his life. Up until the last volume, she has no idea about Migi, until a near death experience may have driven him to use his abilities without Shinichi's realization.
Satomi is played by Ai Hashimoto in the film.
Kana Kimishima (君嶋 加奈 Kimishima Kana)
Voiced by: Miyuki Sawashiro
Kana is a disobedient "bad girl" who develops a crush on Shinichi. She is attracted to him because of his sensitive personality, and because she can sense something "different" about him. In reality, Kana has an unexplained psychic ability to sense Parasites. However, her senses are not as fine tuned as those of the Parasites themselves, and she cannot tell whether she is sensing the presence of Shinichi or of a normal Parasite, putting her in considerable danger. This ability is eventually what leads to her death when she is told about the Parasites, and a total breakdown of Shinichi for a good volume or so, until he recovers from it; the after effects of this lead to estranging him from his friends and get police to keep an eye on him, all of which last until near the final volume.
Yuko Tachikawa (立川 裕子 Tachikawa Yūko)
Voiced by: Kiyono Yasuno (Japanese), Terri Doty[4] (English)
One of Satomi's two best friends. Her brother works as a criminal profiling illustrator for the police departement. Due to her seeing her brother's sketches of Parasites and her crush on Hideo Shimada, she ended up at the center of a highly dangerous situation.
Akiho Suzuki (鈴木 アキホ Suzuki Akiho)
Voiced by: Rena Maeda
The other of Satomi's two best friends, who has a minor crush on Shinichi.
Uragami (浦上)
Voiced by: Hiroyuki Yoshino (Japanese), Andrew Love[4] (English)
A serial killer and cannibal who has the ability to distinguish between humans and Parasites. He is brought in by the military to help them in their operation to exterminate the Parasites in East Fukuyama City, but escapes when the military unit is slaughtered by Goto. He returns at the end of the series and attempts to kill Shinichi and Satomi.
Kazuyuki Izumi (泉 一之 Izumi Kazuyuki)
Voiced by: Masaki Aizawa (Japanese), Rob Mungle[4] (English)
Kazuyuki is Shinichi's father. Shortly after his wife was killed by a Parasite, he had some suspicions as to whether or not Shinichi was infected (although he never said so outright).
Nobuko Izumi (泉 信子 Izumi Nobuko)
Voiced by: Chieko Sasai (Japanese), Allison Sumrall[4] (English)
Nobuko is Shinichi's mother. She dies early on when she is killed and her body taken by a Parasite, and her Parasite form stabs Shinichi through the heart when he refuses to realize that 'Nobuko' is not who she appears to be; the Parasite is later killed by Shinichi and Uda working together.
Kazuki Nagai (長井 和輝 Nagai Kazuki)
Voiced by: Shinya Hamazoe
Mitsuo (光夫)
Voiced by: KENN
A student from Kana's school and possibly her ex-boyfriend, he is jealous of her crush on Shinichi.
Makiko Hayase (早瀬 真樹子 Hayase Makiko)
Voiced by: Yū Serizawa
Makiko is a young schoolgirl who lives with her parents, grandfather, and younger brother in the small town where Shinichi's father is hospitalized. Her family owns a hotel in the town where Shinichi stays for a few days, in order to be near his father. It is shown that she develops a crush on Shinichi during his stay.
Mamoru Uda (宇田 守 Uda Mamoru)
Voiced by: Takuma Suzuki
Uda is, like Shinichi, a human who had a Parasite merge with a part of his body other than his brain. In Uda's case, the Parasite took over the lower part of his head and face, most notably his jaw. Uda's Parasite originally does not have a name, but is later renamed Joe (ジョー , after the english word "jaw") (Voiced by: Ayumu Murase). It is brash and crude—it even seems to have a sense of humor—and often assumes control of Uda's mouth, distorting it into odd shapes and forcing Uda to say strange or inappropriate things. The pair befriends Shinichi and Migi, but prefers to simply avoid Parasites. Because Uda is slightly overweight and his Parasite is located in the jaw area, fights with other Parasites tend to leave him out of breath. However, because it is located in the lower part of the head, his Parasite can extend itself downward into his chest, protecting his heart (a primary target for hostile parasites). Uda is a peaceful, easygoing man, but is shown to be nervous under pressure and highly emotional, often crying easily. He works as a hotel employee.
Shiro Kuramori (倉森 志郎 Kuramori Shirō)
Voiced by: Issei Futamata
A private investigator hired by Reiko to spy on Shinichi and caught by Migi when he takes picture of them. When his assistant Taro goes missing, Shiro asks Shinichi to find him, and ends up recording a fight between Shinichi and a Parasite. Later his family is killed by Parasites, and in a frenzy of grief he kidnaps Reiko's infant son, leading to a critical confrontation at a park.
Takeshi Hirokawa (広川 剛志 Hirokawa Takeshi)
Voiced by: Yuu Mizushima
Hirokawa is the leader of a cabal of Parasites which has Reiko and Goto among its members. The group attempts to accrue political power in order to set up safehouses where they can safely kill and eat their victims in secret. Hirokawa gains election to the office of mayor in East Fukuyama City, a small town (by Japanese standards) of 500,000 people close to Shinichi's hometown. Hirokawa wins by running on a campaign centered on locally based environmentalism. Secretly, Hirokawa is a radical environmentalist who believes that the Parasites' purpose is to cull the human population, standing one step above them on the food chain. The police force kills Hirokawa and discovers that he was never a Parasite, but a human Parasite sympathizer.
Hirama (平間)
Voiced by: Takuma Suzuki
A veteran detective who first suspected Shinichi for Kana's death.
Yamagishi (山岸)
Voiced by: Rikiya Koyama
A police officer assigned to the Parasyte Extermination Squad. He is killed by Gotoh.
Mitsuyo (美津代)
Voiced by: Seiko Fujiki


Reiko Tamura (田村 玲子 Tamura Reiko)
Voiced by: Atsuko Tanaka (Japanese), Maggie Flecknoe (English)
A Parasite who infected and took on the identity of a woman named Ryōko Tamiya (田宮 良子 Tamiya Ryōko), one of Shinichi's high school teachers. Reiko has scientific inclinations, and is driven to discover the biology, origin, and purpose of Parasites. Reiko discovers—by becoming impregnated by another Parasite named Mr. A—that a pregnant body controlled by a Parasite will bear a normal, human child, and that Parasites have no apparent means of reproduction. This however came at the cost of losing her job for bearing a "fatherless" child. After killing off Ryōko's parents, the Parasite changed its looks and created a new identity known as "Reiko Tamura". Reiko is more logical and reasonable than many other Parasites, and allows Shinichi to live unmolested largely because she finds him an interesting anomaly worthy of study. She eventually gives birth to Mr. A's baby; after betraying her fellow Parasites and killing quite a few of them, she lets the police brutally kill her in an ambush in a park instead of trying to resist or escape. The baby survives because of her protection and decision not to fight back against or run away from the police.
Tamura is portrayed by Eri Fukatsu in the film.
Mr. B (B)
Voiced by: Tōru Nara
Mr. A (A Ē)
Voiced by: Makoto Yasumura (Japanese), David Wald (English)
Mr. A is a Parasite who considers Shinichi a threat. Reiko calls him a fool while Migi describes him as "not one of our smart ones". Mr. A has no capacity for subtlety or deception, and no qualms about using his shapeshifting abilities in view of the public, reasoning that he can always get out of trouble by fighting, running away, and changing into a different face. Mr. A (or rather, his host body) is the father of Reiko's child. Shinichi is forced to battle Mr. A when he attempts to hunt Shinichi down and kill him at school. Though Shinichi and Migi badly wound him, they are forced to flee before they could destroy him. Reiko finally kills him for endangering her human cover.
Hideo Shimada (島田 秀雄 Shimada Hideo)
Voiced by: Akira Ishida
Hideo is a Parasite with a teenager's body who decides to integrate with human society. Hideo enrolls in Shinichi's high school and expresses a desire to become friends with Shinichi, who does not trust him. Although Hideo is a relatively peaceful Parasite, he has no qualms about brutalizing or even killing bullies who try to start fights with him, and he continues to hunt humans (although he claims that he is learning to eat normal food instead). After another student discovers his secret and confronts him about it, he goes on a killing spree. He is killed after he escapes to the roof, when Shinichi, using Migi to enhance his right arm's strength, throws a well-aimed stone through his chest, destroying his heart.
Kusano (草野)
Voiced by: Takaya Aoyagi
Gotou (後藤 Gotō)
Voiced by: Kazuhiko Inoue
Gotō is an 'experimental' Parasite created by Reiko. He is actually a combination of several Parasites, whose shapeshifting ability has advanced to the point where they can switch positions, each forming a different limb as the situation requires. Gotō is the most intelligent and skilled, and is the de facto leader of the composite body. Because his head and all of his limbs are made of Parasite cells, Gotō is much faster, stronger, and more dangerous than standard Parasites, and nearly impossible to injure. Gotō is able to use the Parasites in his legs to change the shape of his feet and ankles to give him an advantage in mobility, or speed, when fighting. Gotō is the last Parasite that Shinichi and Migi take down; Gotō actually ends up causing the temporary death of Migi, and absorbs Migi into his body for a small period of time. Shinichi is left with only one arm during this period, but manages to recover Migi and secure victory. The name "Gotō" is a pun as one of the kanji is synonymous with the kanji for five ( go), implying he can control 5 Parasites,.[8]

Miki (三木, lit. Three trees)

Voiced by: Daisuke Namikawa
One of the experimental Parasites created by Reiko in Gotou's body. Similar to "Migi", Miki's default position in the body is the right arm. His name has an additional meaning, which means "Three trees", referencing how he is only able to manipulate 3 Parasites in the body (including himself) when he takes the head position. Unlike other Parasites, Miki has learnt to show emotions just like humans.[8] His body is composed of five parasites, one in each of his arms and legs and another in his head, they can apparently swap their places in the body but only two of them are able to unify the five and make them fight as a single being.

Names in Tokyopop publication[edit]

In the Tokyopop publication the main character's name was Shin and his hand was called "Lefty'", as the image had been flipped to read left to right.[9] Satomi Murano is Sara. Jaw, Uda's Parasite is referred to as Jaws, in reference to the film Jaws by Peter Benchley. Tamura is known as Tamara Rockford in the Tokyopop version.[10] Gotō's name was written without a macron.


Iwaaki chose a high school setting due to a scene he had thought of. When considering a scene where Migi turns his shape into a penis in front of Satomi Murano, Iwaaki believed that the scene would work best in a high school setting, so Iwaaki gave Parasyte a high school setting.[11]



Parasyte was originally serialized in Japan in the Morning Open Zōkan[12] from 1988 and switched to Afternoon after a few issues in 1990.[12] It was collected into ten tankōbon volumes by Kodansha, and was later republished in eight kanzenban volumes. It was originally licensed for English translation and North American distribution by Tokyopop, which published the series over 12 volumes. The Tokyopop version ran in Mixxzine.[citation needed] Daily pages from the Tokyopop version ran in the Japanimation Station, a service accessible to users of America Online.[13] The Tokyopop English-language manga went out of print on May 2, 2005.[14] Del Rey Manga later acquired the rights to the series,[15] and published eight volumes following the kanzenban release. Kodansha Comics USA later republished the volumes in North America between 2011 and 2012.

Live-action films[edit]

Hollywood's New Line Cinema had acquired the film rights to Parasyte in 2005,[16] and a film adaptation was reported to be in the works, with Jim Henson Studios and Don Murphy allegedly in charge of production.[17] New Line Cinema's option expired in 2013, prompting a bidding war in Japan. Film studio and distributor Toho won the rights, and decided to adapt the manga into a two-part live-action film series directed by Takashi Yamazaki. The first part, Parasyte: Part 1, was released in November 2014 and the second part, Parasyte: Part 2, was released in April 2015.[18]


An anime television series adaptation by Madhouse titled Parasyte -the maxim- (寄生獣 セイの格率 Kiseijū Sei no Kakuritsu?) aired in Japan on NTV between October 8, 2014 and March 25, 2015.[19] The series was simulcast by Crunchyroll outside of Asia and by Animax Asia in Southeast Asia and South Asia.[20][21] Sentai Filmworks has licensed the anime for North America, South America, United Kingdom, Australia, and New Zealand release.[22] UK Distributor Animatsu Entertainment will release the series in the UK.[23] The opening theme song is "Let Me Hear" performed by Fear, and loathing in Las Vegas. The ending theme is "It's the Right Time" performed by Daichi Miura. At Anime Expo 2015, Sentai Filmworks has announced that the anime will run on Adult Swim's Toonami block on October 3, 2015.[24][25]


The series won the Kodansha Manga Award for general manga in 1993. It also won the Seiun Award for being the best manga of the year in 1996.[26] The live action film Parasyte: Part 1 had grossed around ¥800 million at the Japanese box office after two weeks.[27]
