👽 Story Overview:

Premise:

One night, strange parasitic organisms fall to Earth. These alien parasites burrow into the brains of humans, take control of their bodies, and live in disguise—feeding on other humans to survive.

One parasite tries to take over 17-year-old Shinichi Izumi, but it fails to reach his brain and instead merges with his right hand. This parasite, later named Migi ("right" in Japanese), retains its own mind and intelligence but is now symbiotically bonded with Shinichi.

Unlike other infected humans, Shinichi retains his personality, making him a unique anomaly—a human with a parasite. As parasitic killings escalate, Shinichi is forced into violent encounters while struggling with his humanity.

🧬 Major Themes:

• What does it mean to be human?
  As Shinichi and Migi fight other parasites, the line between human and monster blurs. Who is more monstrous—emotionless aliens or violent humans?

• Symbiosis and Evolution:
  The relationship between Shinichi and Migi evolves from distrust to cooperation, highlighting adaptation, coexistence, and the power of empathy.

• Identity and Change:
  Shinichi undergoes emotional and physical changes as Migi’s influence grows. He becomes colder, stronger, and detached—raising questions about how much of his original self remains.

• Morality and Survival:
  Parasites act on pure instinct, but they begin to question their purpose. Is survival enough? What does moral responsibility mean to a non-human being?

🧠 Conclusion (Spoiler-lite):

By the end, Shinichi must reconcile his own humanity with the violence he's committed. The story closes not with clear triumph but with philosophical reflection—asking whether humans are any less parasitic to the Earth than the creatures they feared.
