Description
Kokoro is an elderly mermaid who serves as the stationmaster of Shift Station and the primary conductor of the Puffing Tom, the sea train that connects Water 7 to Enies Lobby. In her younger years, she worked as the secretary for the legendary shipwright Tom as part of his shipbuilding group, Tom's Workers, where she came to know a young Iceberg and Franky. The deep grief she experienced following Tom's arrest and execution led her to turn to heavy drinking, a habit she maintains alongside her lively and carefree demeanor.
Despite her age and eccentric, boisterous personality, Kokoro is highly knowledgeable, competent, and possesses a strong moral compass. She lives with her young granddaughter, Chimney, and their pet rabbit, Gonbe, at the remote Shift Station. Her primary motivation is to provide a stable life for her family and operate the sea train she is deeply familiar with.
When the World Government agent organization CP9 frames Iceberg and kidnaps Nico Robin during the Water 7 incident, Kokoro demonstrates immense courage. Recognizing the injustice, she risks her safety and her position to aid the Straw Hat Pirates. She uses her intimate knowledge of the sea train's schedule and capabilities to pilot the Puffing Tom on a dangerous emergency run directly to Enies Lobby, playing a crucial role in the pirates' rescue mission and their defiance of the World Government.
A significant element of her character is the revelation of her true nature as an icefish mermaid. This fact explains her exceptional swimming ability and connects her to the wider aquatic world, defying common expectations about mermaid appearances. Her primary abilities include her unmatched technical expertise in operating and maintaining the sea train, her extensive local geographical knowledge, and her physical resilience as a mermaid. While she does not undergo a drastic personal transformation, her role deepens as she moves from a seemingly simple, eccentric background figure to a brave ally who takes direct action in a major conflict, embodying the idea that courage and moral conviction are not limited to young warriors. After the events of the Enies Lobby arc, she returns to her duties at Shift Station, continuing to serve as a vital link in the community.
