Movie
Description
Coo is a kappa, a mythical Japanese water spirit bearing the features of a humanoid turtle-frog hybrid, complete with a bird-like beak, a shelled back, and a water-filled depression atop his head vital to his existence. His origins reach back roughly 200 years to the Tokugawa era, where he lived peacefully with his father in a swamp. Their existence shattered when a samurai murdered his father during a clash over human encroachment. Fleeing the trauma, Coo fell into an earthquake fissure, desiccated into a fossil, and remained preserved underground.
Rediscovered in modern Tokyo by elementary school student Koichi Uehara, Coo revived when washed in water. He awoke to a world utterly transformed, his swamp home replaced by urban sprawl, leaving him grappling with profound loneliness and displacement, convinced he was the last kappa. Though initially wary of humans because of his father's fate, he gradually bonded with the sheltering Uehara family. He forged an especially close telepathic bond with their dog, Ossan, who became his confidant and emotional anchor.
Driven by curiosity about the modern world and a yearning to find other kappa, Coo journeyed with Koichi to the rural, folklore-rich region of Tono. There, a zashiki-warashi house spirit revealed she hadn't encountered another kappa in over a century, deepening his isolation. Back in Tokyo, media exposure disrupted his life. A traumatic television appearance culminated in a cryptid expert displaying his father's severed arm, triggering a psychic outburst. Coo reclaimed the arm, but Ossan died during their escape.
Grief-stricken and contemplating suicide atop a radio tower, Coo was intercepted by a benevolent water dragon. This supernatural entity urged him to persevere. His subsequent departure from the Uehara family was prompted by a letter from another mythical being. Relocating to Okinawa, he joined a kijimuna forest spirit. This being offered to mentor him in shape-shifting and adopted the name "Ossan" to honor the deceased dog. Carrying his father's arm, Coo committed to continuing his search for surviving kappa while holding hope to reunite with the Uehara family. His journey embodies themes of extinction, adaptation, and the coexistence of melancholy and resilience in navigating loss and forging new connections.
