Nikolai Plisetsky is a supporting character in the anime Yuri!!! on Ice. He is the grandfather of the Russian figure skating prodigy Yuri Plisetsky. An elderly man with short gray hair, green eyes, and often seen wearing a cap, Nikolai embodies a quiet and kind presence. He is a gentle gentleman who speaks little and prefers to listen attentively, especially when his grandson talks. His role in the story is primarily a familial one, centered on his genuine and loving care for Yuri. He is shown performing warm, everyday acts of support, such as picking Yuri up from Sheremetyevo International Airport after his travels, preparing homemade pirozhki for him, and taking an active interest in learning about his grandson's likes and interests. His key relationship is with Yuri Plisetsky, to whom he serves as a stable and affectionate guardian figure. While the series does not explore Nikolai's own background in depth or show a personal arc of development, his consistent presence highlights the importance of family support in Yuri's life. His notable abilities are not in skating but in the practical and emotional care he provides, establishing a home environment where Yuri can return. Nikolai's personality is marked by patience, a lack of judgment, and a calm demeanor that contrasts with Yuri's fiery and competitive nature off the ice. He represents a source of unconditional acceptance and quiet strength within Yuri's world.
