Dr. Stone Test

The Dr. Stone 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:

Chrome

Chrome is the exuberant self-taught sorcerer who becomes a true scientist, acting as a scrappy explorer whose curiosity and improvisation bridge primal nature and modern technology. A native villager, he independently discovers basic chemistry and mineralogy, hoarding rocks and conducting experiments long before meeting Senku. His strength lies in exploration and hands-on tinkering, searching landscapes for ore and inventing hydraulic power on the fly. Brave and loyal, he withstands threats without betraying his village and repeatedly risks his life in scientific missions. He represents a relatable, learning-in-public scientist whose genius lies in creative problem-solving rather than just encyclopedic memory, constantly seeking to stand beside Senku as an equal.

Yuzuriha Ogawa

Yuzuriha Ogawa is a gentle craftswoman and emotional anchor whose quiet patience stitches people back together. Reserved and detail-oriented, she uses her exceptional textile skills to support scientific projects and painstakingly reassemble shattered petrified statues, giving victims of the stone world a chance at revival. She listens through long science lectures, acts as a covert spy, and throws herself into infrastructure once civilization advances. Though often overlooked in a cast of loud geniuses, she is the heart of the journey. Her resilience is hidden behind politeness, proving that rebuilding the world depends as much on nurturing effort as it does on grand heroics.

Gen Asagiri

Gen Asagiri is the charming mentalist-trickster—a consummate liar who weaponizes psychology, theatrics, and social insight for survival and, ultimately, for his friends. A former professional magician and TV mentalist, he is a master of persuasion, bluffing, and reading people, calling himself the world’s smoothest talker. Initially a spy, he becomes a key strategist for the Kingdom of Science, oscillating between a work-avoiding airhead and a razor-sharp tactician. He cultivates an image of a shallow opportunist to hide his deep loyalty and empathy. He uses his masks and social ambiguity to protect his allies, proving that his greatest deceptions are often acts of genuine care.

Tsukasa Shishio

Tsukasa Shishio is a physically overwhelming warrior-philosopher who attempts to remake society by culling its corrupt elements. Famous as Japan's strongest high-school fighter, he can kill a lion bare-handed and dominates every physical conflict. He articulates a vision to revive only pure-hearted youth and destroy the statues of adults to prevent the return of oppressive systems and addictive technologies. While framed as an antagonist, he is polite, thoughtful, and deeply loving toward his comatose sister. His ideology is morally flawed and inconsistent, yet it is rooted in wounded idealism and a desire to protect the vulnerable from systemic injustice.

Senku Ishigami

Senku Ishigami is a hyper-logical, altruistic scientist-hero who treats knowledge as the ultimate tool and responsibility. As a teenage prodigy who awakens in a world reclaimed by nature, he vows to rebuild civilization from scratch using the scientific method. He is straightforward, confident, and rigorously logical, constantly applying data to solve problems while admitting mistakes when new information appears. Though he acts cold and manipulative to steer others, he fundamentally refuses to abandon his friends or kill enemies. Under his aloof exterior lies a deeply hopeful belief in humanity, driven by the conviction that science can both explain and uplift every human life.

Taiju Oki

Taiju Oki is a tireless, gentle powerhouse whose superhuman strength and stamina are matched only by his extreme pacifism and unwavering loyalty. He approaches every task, from hauling massive materials to scouting dangerous terrain, with limitless energy and a cheerful, optimistic spirit. Despite his ability to overpower almost any foe, he refuses to throw a punch, choosing instead to endure physical suffering to protect others from harm. His five-year, unconfessed devotion to Yuzuriha fuels his incredible perseverance through millennia of petrification. Beneath his simple, lovable exterior lies a disciplined moral courage and a steadfast commitment to his friends that quietly anchors the Kingdom of Science.

Kohaku

Kohaku is a fierce, impulsive guardian who channels her immense strength into protecting her family and friends while chafing at the restrictive traditions of Ishigami Village. As the village's strongest fighter, she is agile, sharp-eyed, and physically powerful enough to haul heavy loads daily for her sick sister, Ruri. She is blunt and often acts first to rescue others, yet she remains deeply nurturing toward those she loves. Though she appears to be a classic tomboy brawler, she secretly meditates on abstract ideas and deliberately cultivates a rough image to avoid being forced into a ceremonial role that would compromise her sister's spirit.
