# Parasyte

Parasyte (Japanese: 寄生獣, Hepburn: Kiseijū, lit. 'Parasitic Beasts') is a Japanese science fiction horror manga series written and illustrated by Hitoshi Iwaaki. It was published in Kodansha's Morning Open Zōkan (1989) and Monthly Afternoon (1989 to 1994). The manga was published in North America first by Tokyopop, then Del Rey, and finally Kodansha USA. The series follows Shinichi Izumi, a high school senior who is the victim of a failed attempt by a parasitic organism to take over his brain. The parasite, Migi, instead infects and takes over his arm, and both are forced in a peculiar partnership to fight other parasites.
The manga has been adapted into two live-action films in Japan, in 2014 and 2015. An anime television series adaptation produced by Madhouse, titled Parasyte -the maxim-, aired in Japan between October 2014 and March 2015. The English-language dub aired on Adult Swim's Toonami programming block in the United States between October 2015 and April 2016.
By August 2022, the manga had over 25 million copies in circulation, making it one of the best-selling manga series of all time. In 1993, Parasyte received the 17th Kodansha Manga Award for the general category, as well as the 27th Seiun Award for the best manga in 1996.

## Plot

Parasyte centers on a 17-year-old male high school student named Shinichi Izumi, who lives with his mother and father in a quiet neighborhood in Fukuyama, Hiroshima, Japan. One night, tiny worm-like aliens with drill-like heads called Parasites arrive on Earth, taking over the brains of their hosts by entering through their ears or noses. One Parasite attempts to crawl into Shinichi's nose while he sleeps, but fails as Shinichi wakes up, 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".
Because Shinichi was able to prevent Migi from traveling further up into his brain, both beings retain their separate intellects and personalities. As the duo encounters 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 other members of the species they infect as food, while enlisting Migi's help.
The series explores philosophical and psychological questions such as the meaning of humanity, humans' relationship to the environment and other species, the role of instinct and love, and the inherent anthropocentrism of morality. Shinichi's experience with Migi causes him to question if humanity has any right to claim moral superiority to the Parasites, while Migi and Reiko Tamura's experiences with humans cause them to take on more human traits, such as love and sacrifice.

## Development

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 that setting.

### Live-action films

Hollywood's New Line Cinema had acquired the film rights to Parasyte in 2005, and a film adaptation was reported to be in the works, with Jim Henson Studios and Don Murphy allegedly in charge of production. New Line Cinema's option expired in 2013, prompting a bidding war in Japan.

The first part, Parasyte: Part 1, was released in November 2014 and the second part, Parasyte: Part 2, was released in April 2015.

## Reception

Parasyte won the 17th Kodansha Manga Award for the general category in 1993. It also won the 27th Seiun Award for being the best manga of the year in 1996. On TV Asahi's Manga Sōsenkyo 2021 poll, in which 150,000 people voted for their top 100 manga series, Parasyte ranked 60th.
By November 2013, the manga had over 11 million copies in circulation. By December 2020, the manga had more than 24 million copies in circulation; it had over 25 million copies in circulation by August 2022.
The manga series has been praised and recommended by Waseda University professor and literary critic Norihiro Kato [ja], and by philosopher Shunsuke Tsurumi. The manga artist Machiko Satonaka praised the work and described it as "a masterpiece that makes you think about fundamental problems that raises the awareness of identity establishment". Connie Zhang of Mania.com ranked the first volume of Parasyte as A−. Zhang wrote that the series' main focus is the dynamic relationship between Shinichi and Migi and their discussions about human nature. Zhang stated: "It is this casual philosophical pandering that makes Parasyte a cerebral manga. As the parasytes gradually adapt to human life and become cleverer at disguising their true identities, Shinichi finds himself in more and more danger". She concluded: "Parasyte is not just about a teenager saving the world. It is about a teenager at the cusp of adulthood and his cynical, mutinous right hand...saving the world. Highly recommended".
The anime adaptation by Madhouse was well received by critics and fans alike, getting praise for the animation, characterization, pacing and the soundtrack of the anime. In November 2019, Crunchyroll listed Parasyte -the maxim- in their "Top 100 best anime of the 2010s". IGN listed it among the best anime series of the 2010s.

### China ban

On June 12, 2015, the Chinese Ministry of Culture listed Parasyte among 38 anime and manga titles banned in mainland China. Nonetheless, the live-action version of Parasyte managed to be released in nationwide cinemas across mainland China, using a 125-minute special cut which condensed part 1 and part 2.
