Shizuka Minamoto is a central character in "Doraemon: Obāchan no Omoide," where she acts as a supportive friend to Nobita Nobi. She stands by him when he rediscovers an old teddy bear from his grandmother and witnesses his emotional distress. Her kind and compassionate nature leads her to comfort Nobita and join him and Doraemon on a journey through time to visit his younger self and late grandmother, offering moral support during this emotional event. The story also reveals her long-standing friendship with Nobita through a glimpse of her younger self. In the broader franchise, Shizuka is destined to become Nobita's wife, a thread explored in "Stand By Me Doraemon 2." In that adaptation, Nobita's grandmother expresses a desire to see his future bride, prompting a trip to the future. Complications emerge when the adult Nobita flees his wedding to Shizuka, causing worry among his friends. Shizuka is consistently portrayed as smart, kind, and caring, often showing concern for weaker individuals, mistreated animals, and neglected dolls. She aspires to become a nurse or an air hostess, reflecting her nurturing personality. Responsible and studious, she dislikes video games and enjoys bathing several times a day. Her interests include playing the violin poorly, a trait humorously highlighted in the series, and she loves sweet potatoes and baking, frequently sharing cakes and cookies with Nobita and Doraemon. She is also a fan of magical girl cartoons. Among her relationships, Shizuka is a close friend to Nobita, Doraemon, Gian, and Suneo. She often becomes upset with Nobita for his rudeness or when he interrupts her bath time, but she consistently forgives him due to her admiration for his kind heart. She cares deeply for all her friends, showing concern even for Gian when she believes he is hurt, yet she stands up to Suneo's selfishness by threatening to reject his invitations if he excludes Nobita. She also maintains a friendly academic relationship with Hidetoshi Dekisugi, often studying alongside him. Shizuka has a good relationship with her parents, sharing a particularly close bond with her father, who supports her decisions. She owns a pet canary named Peeko that has a habit of running away.
