Fujimoto, a once-human sea sorcerer, serves as the ocean’s caretaker from his underwater harbor home, where he lives with his many daughters. Tasked with restoring marine balance, he combats human pollution using potions and elixirs refined since 1907. Towering at 196 cm with a lean build, he cuts a striking figure with long crimson hair, turquoise eyes, and unique markings—azure shadows beneath his eyes and rosy cheek stripes. His flamboyant wardrobe features pinstriped suits, a magenta cravat, and a dark magenta coat fastened by golden clasps. A fiercely overprotective father to Ponyo and her sisters, Fujimoto’s distrust of humanity fuels his desire to revert the ocean to its primordial state, a mission rooted in his own human past. His clashes with Ponyo escalate when she flees to the surface, defying his isolationist ideals. Though stern, his love for his daughters endures, strained by the absence of his wife, Granmamare, the sea goddess, whose divine duties keep her distant. Skilled in crafting vitality-boosting potions, summoning water spirits for surveillance, and conjuring protective bubbles, Fujimoto’s magic remains overshadowed by his daughters’ inherited divine prowess. Land excursions demand a seawater humidifier to counteract his vulnerability to dehydration. When retrieving Ponyo, he dispatches water spirits and confronts Sosuke’s family but refrains from violence, prioritizing intimidation over harm. His rigid worldview wavers after Granmamare intervenes, proposing a test for Ponyo’s future. Initially doubting Sosuke’s ability to love Ponyo unconditionally, Fujimoto reluctantly accepts the boy’s resolve, permitting Ponyo’s transition to humanity. This evolution highlights his concealed tenderness beneath ecological zeal. Interactions with surface dwellers, like elderly nursing home residents, further unveil his capacity for measured patience and unexpected courtesy, complicating his brusque exterior.
