Loop Nishigori is one of the six-year-old triplet daughters of Takeshi and Yuuko Nishigori, making her part of the family that runs the Ice Castle Hasetsu rink in the town of Hasetsu. She and her sisters, Axel and Lutz, are named after figure skating jumps—in Loop's case, the loop jump. Loop has brown hair styled in a ponytail, brown eyes, and a color scheme dominated by pink. As young children, they are active and curious, often seen at the ice rink or around their parents. Their most notable action in the story is uploading a video of Yuuri Katsuki skating Victor Nikiforov's program Stay Close to Me to social media. This video goes viral and directly leads to Victor traveling to Japan to become Yuuri's coach, setting the entire series in motion. Beyond this catalyst role, Loop and her sisters appear as supportive, energetic background characters who cheer for Yuuri, attend his competitions, and represent the close-knit community of Hasetsu. Her personality is not deeply explored due to her minor role, but she is portrayed as playful and enthusiastic, typical of a young child. Her motivations are simple: she enjoys skating, spending time with her family, and supporting Yuuri. Her key relationships are with her parents Takeshi and Yuuko, her two sisters, and the protagonist Yuuri Katsuki, whom she has likely known since birth. Loop does not undergo significant personal development over the course of the series, as her screen time is limited, but her presence helps ground the story in a warm, familial environment. Her notable abilities are not athletic or skilled in any exceptional way; rather, her main contribution is her inadvertent role in launching the plot through the video upload. She appears primarily in the early episodes of the anime and in brief cameos later, often alongside her sisters.
