Senku Ishigami, a teenage prodigy with encyclopedic mastery of chemistry, physics, engineering, and astronomy, was adopted by astronaut Byakuya Ishigami in the 21st century. When a global petrification event turned humanity to stone for 3,700 years, Senku maintained consciousness, meticulously counting each second to preserve his grasp on time. Revived millennia later, he spearheads the reconstruction of civilization through science, founding the Kingdom of Science and ascending as chief of Ishigami Village after curing its priestess, Ruri. His striking appearance features pale skin, sharp crimson eyes, and white hair fading to green at the tips. Post-revival, he wears a leather tunic marked near the collarbone with Einstein’s E = mc² formula in dried blood. A dark cloak gifted by Suika, symbolizing their alliance, replaces this after his South American revival. Jagged petrification scars once etched across his face healed following a subsequent revival in a rocket. Driven by unyielding logic and selflessness, Senku champions scientific advancement while safeguarding human life. He orchestrates strategic alliances and calculated deceptions—such as faking his death to shield Yuzuriha from Tsukasa—yet adamantly refuses to sacrifice allies. Though indifferent to romance, he encourages others’ pursuits of it. His charisma and innovations, from ramen to life-saving medicine, forge loyalty among followers, uniting disparate factions under his leadership. A genius intellect, mental endurance, fluency in Morse code and English, and tactical ingenuity define his capabilities. He engineers revival fluid and communication devices but partners with artisans like Kaseki for intricate craftsmanship. Limitations include physical frailty and occasional gaps in expertise, such as miscalculating Earth’s precession or stone tool methods. Senku resolves conflicts through nonviolent ingenuity, dismantling Tsukasa’s empire via truces and reviving Tsukasa’s sister Mirai to broker peace. After a second global petrification, Suika single-handedly revives him years later, enabling mass revival of allies and the discovery that depetrification heals fatal wounds. Collaborating with former adversary Xeno, he designs a rocket to confront Why-Man, the petrification’s source, while establishing settlements like Superalloy City. His journey transitions from solitary scientist to visionary leader, blending scientific rigor with diplomatic pragmatism. By elevating Stone Age society to spacefaring capability, Senku cements a legacy where science, in his view, universally uplifts humanity.
