Parasyte — Timeline11 events
Parasitic Organisms Appear on Earth — Infestation of Humans Begins
Unidentified microscopic organisms appeared on Earth and began burrowing into sleeping humans through their ears and noses, taking over their hosts' brains. Parasitized humans retained their outward appearance while secretly preying on other people. These events were initially reported as a series of bizarre serial killings.
Shinichi Izumi Prevents Full Parasitism — Begins Coexistence with Migi
High school student Shinichi Izumi woke up during a parasite's invasion attempt, preventing it from reaching his brain. The organism burrowed into his right arm instead and replaced his right hand. Naming itself 'Migi' (Right), the creature proved highly intelligent, and an unusual symbiotic partnership between the two began.
Ryoko Tamura Appears — A Parasite Disguised as a Teacher
Ryoko Tamura, a teacher who transferred to Shinichi's school, was a parasite that had taken over the original Ryoko Tamura. Exceptionally intelligent and adaptive, this parasite studied human society and bore a child with a human man, displaying behavior highly unusual among her kind.
Shinichi's Mother Is Taken Over — His Transformation Begins
During a trip with her husband, Shinichi's mother was killed by a parasite that took over her body. The parasite later stabbed Shinichi through the heart; only the dispersal of Migi's cells throughout his body saved his life. From this point on, Shinichi's emotions became markedly dulled while his physical capabilities increased dramatically.
Hirokawa Rises — The Parasite Mayor's Political Machinations
Hirokawa, a parasite, sought to protect his kind through political power and won election as mayor of Higashifukuyama City. His city hall headquarters became a gathering place for parasites including the powerful Goto, and the organization worked to infiltrate and conceal their existence within human society.
Ryoko Tamura's Transformation — Maternal Attachment and Defiance of Her Own Kind
Ryoko Tamura gradually came to see value in the life of the child she had borne, as she observed it over time. Regarded as a threat by other parasites, she was hunted by her own kind and ultimately entrusted her baby to Shinichi Izumi before dying. Her actions were unprecedented among parasites and left a deep impression on Shinichi.
Police and Self-Defense Forces Storm City Hall
With Hirokawa's organization identified by the authorities, police and Self-Defense Forces launched an operation on Higashifukuyama City Hall. Mayor Hirokawa was shot dead, but Goto — an experimental parasite created by merging multiple organisms — appeared and overwhelmed the SDF troops one after another, single-handedly destroying the assault unit.
Final Battle with Goto — Industrial Waste Turns the Tide
Shinichi and Migi engaged Goto in a final confrontation. Goto had inadvertently absorbed illegally dumped toxic industrial waste, which degraded his capabilities. Seizing this opportunity, Shinichi and Migi delivered a mortal wound, and Shinichi finished Goto off himself — the decisive end to the parasite threat.
Uragami's Chase — Final Scene on the Rooftop
Uragami — a serial killer with the uncanny ability to sense parasites — reappeared after his escape and lured Shinichi to a rooftop by taking Satomi hostage. Migi awakened once more to neutralize Uragami, saving Satomi. After the crisis, Migi told Shinichi that he would soon return to a deep and lasting sleep.
Migi Falls Into Deep Sleep — Parting with Shinichi
With the parasite organization destroyed and Goto dead, Migi informed Shinichi of his intention to sleep. From then on, Migi entered a deep slumber within Shinichi's right arm and no longer awakened under normal circumstances. The story suggests Migi's sleep may last for the rest of both their lives.
Shinichi Izumi and Satomi Murano's New Beginning — Shinichi as a Ronin Student
With the parasite threat over, Shinichi found himself a year behind in schooling due to the turmoil of high school and set out to reach university as a ronin student. His relationship with Satomi continued, and the two began reclaiming an ordinary life. Shinichi's emotions also gradually returned toward something more human.
