Parasyte

Parasyte is Hitoshi Iwaaki's manga about a quiet invasion. Small parasitic life forms appear on Earth and enter human hosts through the nose or ears, consuming the host's brain and taking over the body. The creatures can reshape their hosts into deadly blades and other forms, then move unnoticed through ordinary society while hunting people. Shinichi Izumi, an ordinary high school student, is attacked by one such parasite, but it fails to reach his brain. Instead it burrows into his right hand and becomes a separate thinking being he calls Migi.

Shinichi and Migi are forced into an uneasy partnership. Migi is coldly logical and concerned mainly with survival, while Shinichi remains human and horrified by the killings around him. To stay alive, Shinichi must learn to fight, conceal Migi from family and friends, and recognize that other parasites have already infiltrated schools, homes, and public life. Their encounters with these predators raise difficult questions about what makes a person human and whether humans have any right to judge another species that simply follows its own nature.

The central conflict follows Shinichi and Migi as they face hostile parasites and the growing suspicion of ordinary people. Shinichi is changed physically and emotionally by the bond, and he struggles to protect those close to him without losing his own compassion. The manga mixes body horror, action, and philosophical drama as the two unlikely allies search for a way to survive in a world where the line between monster and human is never simple.

Parasyte is an original manga written and drawn by Hitoshi Iwaaki. It began publication in 1989 and is a finished work, running to 64 chapters that were collected into 10 volumes. Because the series is classified as original source material rather than an adaptation, its production history rests on Iwaaki's own authorship and on the editorial and publishing support of Kodansha, the Japanese rights holder credited alongside the creator on authorized editions of the work.

A later Japanese edition, the complete edition, presents the series in eight volumes. That release gives the manga a distinct production story of its own: covers for volumes one through eight were newly designed, the cover printing uses a special silver foil treatment, and color pages that appeared during the original serialization are reproduced in full. The same edition also gathers question and answer columns from the serialization, giving readers a look at the manga's periodical run alongside the story itself. These features belong to the complete edition of this individual work and reflect how the manga has been reissued and repackaged over time.

Licensing carried Parasyte beyond Japan. Kodansha formally authorized Tongli Publishing to produce a Chinese-language edition, and English-language readers can find the manga through K MANGA, INKR, Naver Webtoon, and Mangas.io. Together these editions mark the manga's path from its 1989 debut to an ongoing international readership.

Parasyte stands as the originating work of its franchise and the main manga entry within it. Serialized from 1989, the ten-volume, sixty-four-chapter series was created by Hitoshi Iwaaki and is cataloged as original source material rather than as an adaptation of an earlier work. The franchise therefore begins here instead of continuing something that came before it.

Later versions and reissues of the story trace back to this manga rather than the reverse. The catalog records it with a main_manga relationship to the broader franchise, marking it as the parent entry from which other installments and editions descend. The complete edition from Kodansha, which redesigns the covers, restores the serialized color pages, and includes the original question-and-answer columns, presents the same material in a collected form for readers who want the full run together.

Within the franchise, this entry functions as the beginning and as a stand-alone original manga. It is not a spin-off, a sequel, or an alternate retelling, but the initial telling of the story that other entries follow or revisit. Its body horror, alien intrusion, and philosophical inquiry establish the tonal groundwork the rest of the franchise draws upon.
