Parasyte: The Maxim Test

The Parasyte: The Maxim Test is inspired by psychometric methodology and based on research into the characters of the anime series. The test provides feedback such as the following:

Shinichi Izumi

Shinichi Izumi is a thoughtful student forced to adapt when a bizarre invasion thrusts him into a quiet war for survival. Responsible and deeply cautious by nature, he steps in to shield others from danger even while overcome by fear. His central struggle lies in balancing his intense desire to preserve his human empathy with the cold, calculating efficiency required to endure constant threats. When crisis strikes, he hides his personal suffering to keep his loved ones safe and relies on sharp analysis to navigate sudden emergencies. Although severe trauma briefly dulls his emotional warmth, he ultimately insists that strength must not replace compassion.

Migi

Migi is a calculating alien parasite who inhabits Shinichi Izumi's right hand and evaluates every situation through cold logic and probability. Driven by self-preservation and curiosity, Migi initially views human emotional bonds as irrational distractions, often recommending ruthless choices during crises. Beneath this detached efficiency lies a remarkable capacity for learning and adaptation. By constantly observing human habits and absorbing vast amounts of information, Migi gradually develops a deep, unspoken loyalty to Shinichi. The parasite uses tactical brilliance and physical transformation to shield their shared existence. Migi ultimately shows care not through sentiment, but through vigilant protection, practical advice, and a lasting commitment to mutual survival.

Reiko Tamura

Reiko Tamura is an intellectually driven parasite who poses as a high school teacher to study human nature and the possibility of coexistence. She operates with cold, methodical curiosity, analyzing human emotions, social structures, and biological drives as abstract data points. Highly composed and strategic, she avoids unnecessary conflict whenever gathering information proves more useful. Her clinical detachment is put to the test when she gives birth to a human child. What begins as a scientific experiment in parenting gradually evolves into genuine maternal commitment. Ultimately, she chooses to shield her infant from destruction, proving that even a purely rational observer can develop deep protectiveness through experience.

Satomi Murano

Satomi Murano is a perceptive high school student whose emotional attentiveness makes her a steady anchor during chaotic times. Cheerful and straightforward, she notices subtle shifts in the people around her and refuses to ignore sudden emotional distance. Her core motive is to maintain authentic, open relationships, yet she finds herself repeatedly shut out by secrets she cannot comprehend. While she experiences fear and suspicion when loved ones change, she chooses persistence over detachment. Satomi confronts secrecy directly with gentle questioning, using her warmth to bring troubled friends back to everyday reality. Her quiet strength lies in trusting observable kindness, remaining loyal, and protecting human warmth when life grows cold.

Kana Kimishima

Kana Kimishima is a rebellious, sensation-seeking teenager whose intense romantic idealism leads her to trust powerful instincts over practical cautions. Confident, easygoing, and independent, she disregards authority and traditional social expectations to pursue what she views as a special connection. Her core motive is finding a meaningful bond, yet her central contradiction lies in confusing overwhelming feelings with proof of destiny. Possessing a rare sensitivity to hidden signals, she misinterprets dangerous warnings as signs of a shared soulmate link. Driven by emotional certainty, she repeatedly risks her personal safety for a romantic ideal, choosing gut feelings over clear advice from those around her.

Gotô

Gotô is an overwhelmingly powerful composite parasite who views combat, dominance, and physical survival as the ultimate forms of existence. Created through an experiment to coordinate multiple organisms within a single host, he acts as a formidable enforcer while seeking opponents capable of testing his limits. He values efficiency and raw strength above moral considerations, pursuing his objectives with singular focus and absolute calm. Despite his predatory nature, he shows genuine respect for rivals who display exceptional skill and courage in battle. Gotô embodies life reduced to competitive force, confronting every challenge directly without letting guilt, hesitation, or sentiment soften his resolve.

Uragami

Uragami is a cynical killer whose dark instincts allow him to sense parasites disguised among humanity. Recruited by authorities to identify hidden monsters, he views himself as the only authentic person in a hypocritical world. He believes that ordinary people merely hide their aggressive impulses behind social rules and moral posturing. Unimpressed by law or institutions, he treats every interaction as a game for his own entertainment. His sharp social awareness lets him easily read the dark secrets of others, turning him into a provocative observer who rejects public norms to pursue immediate personal gratification regardless of the consequences to those around him.
