Kinro, elder brother of Ginro and son of Tetsuken and Shirogane, begins his journey as a guard of Ishigami Village alongside his sibling before aligning with the Kingdom of Science’s Power Team Defense Division. Standing 180 cm tall with a muscular 77 kg frame, his brown hair frames a stern face marked by a right-cheek scar and a long lock hanging between his green eyes. A habitual scowl, partly from nearsightedness, softens slightly after he adopts glasses post-village tournament. His attire evolves from a sleeveless royal blue karate gi with a rope belt and star-patterned buckler to include a katana following Hyoga’s raid. Rigidly principled and duty-bound, Kinro enforces rules with unwavering resolve, refusing Senku entry despite the latter saving Kohaku and resisting the allure of ramen he deems sorcery. His integrity drives him to question the ethics of using Suika’s borrowed glasses during his duel with Magma, seeking Jasper’s counsel afterward. Though initially distrustful of Senku, he grows into a steadfast ally, advocating for the Kingdom of Science while retaining his core values. A master spearman, Kinro wields his weapon with a gilded spearhead gifted by Senku and later demonstrates equal prowess with a katana during clashes with the Empire of Might. His physical strength rivals Ishigami’s elite, matched only by Magma and Kohaku, while his stamina proves vital in manually powering generators until automated solutions emerge. Enhanced eyesight via glasses eliminates his last combat weakness. Named “golden wolf” to complement Ginro’s “silver wolf,” Kinro’s July 9th birthday mirrors gold’s atomic number (79). His evolution from inflexible enforcer to adaptable Kingdom loyalist underscores a journey where duty and principle remain unshaken, even as his methods embrace progress.
