Main Characters and Their Roles in the Story
Below is a brief description of each main character and their role in the story:
- Shinichi Izumi: The protagonist and an ordinary high school student. Through his coexistence with Migi, a parasite residing in his right hand, he gradually transforms into a hybrid being—someone who bridges the gap between humans and parasites.
- Satomi Murano: Shinichi’s classmate and later his girlfriend. Although puzzled by Shinichi’s changes, she continues to believe in his humanity and remains a constant emotional support.
- Migi: The intelligent lifeform that has taken over Shinichi’s right hand. Logical and composed, Migi gradually undergoes changes as he spends time with Shinichi.
- Mamoru Uda: A man parasitized from his mouth to chin. He is one of the rare cases of a human coexisting with a parasite who hasn’t taken over the brain, much like Shinichi.
- Joe: The parasite residing in Uda’s jaw. Rough in speech but loyal, he tries hard to adapt to human society.
- Ryoko Tamiya / Reiko Tamura: A highly intelligent parasite who infiltrates human society. She becomes a researcher of parasite behavior and even awakens to maternal instincts, making her a symbolic figure in the story.
- Gotou: The final antagonist, a formidable parasite composed of multiple parasites within one body. He poses the greatest threat to humanity.
- Takeshi Hirokawa: Mayor of East Fukuyama City. Despite being human, he organizes parasites and advocates for radical environmentalist ideals, harboring a critical view of humanity.
- Kana: A girl with the rare ability to sense parasites. She becomes attracted to Shinichi and, while pursuing him, ultimately loses her life—leaving a lasting impact on him.
- Kuramori: A private detective who loses his family to parasites. Driven by vengeance, he kidnaps Reiko Tamura’s baby, but is shaken upon witnessing her maternal instincts, ultimately gaining insight into her true intentions.
Genre and Thematic Direction
Parasyte goes beyond the realms of science fiction and suspense, incorporating rich human drama and deep philosophical contemplation. While the plot revolves around “coexistence and conflict with parasitic beings that have arrived on Earth,” it also addresses universal themes like “What does it mean to be human?” and “What is the value of life?”
As the story progresses, readers come to realize that the boundary between “humans” and “parasites” becomes increasingly ambiguous. With characters like the logical and emotionless Migi, the maternally awakened Reiko Tamura, and the human Hirokawa who sides with parasites, the work challenges conventional notions of good, evil, and justice.
The narrative also includes modern concerns such as environmental issues and species preservation, giving the series a weight far beyond that of a simple action manga. In the end, it leaves readers with a lingering reflection on what “human nature” truly means.
