### Ryusui Nanami Character Description #### Background and Pre-Petrification Life Heir to the Nanami Group, a multinational shipping empire exceeding 200 trillion yen in assets, Ryusui Nanami radiated intense ambition from childhood, rejecting any notion of surrender to desire. When his father slashed his allowance to 1 million yen over perceived extravagance, Ryusui countered by winning a dodgeball grand prix and mastering financial markets to fund his pursuits. His passion for ships began with model collecting as a child, escalating to captaining real vessels by middle school while declaring himself a "pro adventurer." He sailed globally, hosted extravagant parties, and surrounded himself with companions, earning media scorn as the family's "Black Sheep." Yet he devoted sleepless nights to designing traditional-model ships, dreaming of constructing one full-scale. Petrifaction struck him at Seven Seas Academy mid-command, fingers snapping toward his butler Francois. #### Personality and Philosophy Ryusui's core conviction declares "wanting something is justice," framing desire as the noble engine of progress. He openly claims, "This world will be mine," seeking ownership of everything yet respecting exceptional talent. Though perceived as greedy or arrogant, his ambition transcends self-interest; he uplifts others, insisting money unites rather than controls. He rejects leadership if others excel and readily admits faults. He finds all people beautiful regardless of gender or age, using "love" and "desire" inclusively. Selflessness surfaces in critical moments—shielding allies from danger—and he holds immeasurable faith in his comrades' dedication. #### Abilities and Skills - **Sailing/Navigation**: An expert sailor since youth, he precisely judges ocean conditions and executes complex maneuvers. He captained the Kingdom of Science’s Perseus and later piloted aircraft from hot-air balloons to fighter planes. - **Meteorology**: His "sailor's sense" predicts weather accurately, foreseeing storms through atmospheric shifts. - **Leadership/Economics**: He introduced currency (Dragos) to motivate Stone World productivity and orchestrated large-scale projects like ship construction. His negotiation secured vital resource deals, though he later prioritized collective goals over personal profit. - **Combat/Improvisation**: Physically strong enough to rival elite fighters in contests like tug-of-war, he improvises solutions under pressure—like attaching a microphone to remotely activate petrification devices. - **Technical Aptitude**: He masters new technology swiftly—drones, radar systems—drawing on maritime instrumentation knowledge and model engineering. #### Development in the Stone World Revived by Senku Ishigami for sailing expertise, Ryusui initially demanded oil fields and implemented currency. He clashed with Senku over resources but grew to respect his leadership, eventually contributing skills freely to the Kingdom of Science. His desire-driven ethos fueled innovations in ship designs and economic systems. Petrified and smashed during the Treasure Island conflict, he later revived. He sacrificed himself again securing the petrification device, only to be restored once more. Evolving from self-interested negotiator to committed ally, he declared Suika a "true warrior" after her growth during his petrification. He accepted Senku’s choice of Stanley Snyder over him for the moon mission without resentment. #### Relationships - **Francois**: His devoted butler since childhood, revived for culinary mastery. Francois defends his altruism and shares his philosophy that desire empowers others. - **Senku Ishigami**: Initially rivals in resource control, Ryusui acknowledged Senku as the rightful leader after witnessing his vision. He stated he would have hired Senku pre-petrification. - **Suika**: Initially protective of her as a child, he later recognized her as a full-fledged Kingdom of Science member after her crisis contributions. - **Tsukasa Shishio**: Avoided ideological clashes by framing money as motivation—a concept Tsukasa accepted, ensuring tension-free interactions. - **Chrome**: Bonded through shared enthusiasm for adventure, collaborating during airborne emergencies and strategic missions. - **Minami Hokutozai**: Corrected her negative impression by proving selfless intent, like promising her photographs a museum home. #### Key Contributions - Designed and captained the Perseus, enabling global exploration. - Founded the Ryusui Foundation to restore economic systems. - Located petrified individuals underwater using improvised diving gear. - Repelled the Why-Man threat by operating critical technology during planetary conflicts. - Holds the record for most petrifications and revivals (six times), his statues often frozen in dramatic poses. Ryusui’s legacy transforms personal greed into collective progress, proving desire a catalyst for rebuilding civilization.
