Shizuka Minamoto appears in the short film "Doraemon Comes Back," playing a supportive role during the emotional climax. Following Doraemon's departure, she shows heartfelt concern for Nobita after Gian and Suneo trick him into believing Doraemon has returned, intensifying his grief. When Doraemon unexpectedly reappears, Shizuka joins Gian and Suneo in visiting Nobita to offer comfort. Her presence contributes to the group's reconciliation and shared joy at Doraemon's return.
Across official media, Shizuka consistently displays kindness and empathy. She cares deeply for others, especially those vulnerable or distressed like Nobita during bullying. She champions fairness and inclusivity, threatening to reject Suneo's invitations if he excludes Nobita. Her compassion extends to animals and nature, such as rescuing trapped birds or grieving over the loss of the Grandfather Tree.
Shizuka's relationship with Nobita is multifaceted. She frequently encourages him during academic or personal struggles and assists him when injured or bullied. While she becomes angry at his irresponsible actions—like interrupting her violin practice or accidentally intruding on her baths—she readily forgives him when he shows kindness or genuine remorse. Their bond evolves into marriage in the future, where they have a son named Nobisuke. Shizuka accepts Nobita's proposal based on her belief in his inherent goodness, contrasting her polite but platonic friendship with the academically gifted Dekisugi.
Shizuka possesses distinct interests and quirks. She enjoys bathing multiple times daily and passionately plays the violin, though her notably poor skills often disturb neighbors. She secretly loves sweet potatoes, collects dolls, and watches cartoons featuring heroic themes. Her career aspirations include nursing or becoming an air hostess, reflecting her nurturing disposition.
She maintains civil relationships with Gian and Suneo despite disapproving of their bullying. While attending Gian's concerts or Suneo's gatherings out of politeness, she openly challenges their exclusionary behavior toward Nobita. Her ability to mediate is evident when she facilitates Gian and Suneo's apology to Nobita in "Doraemon Comes Back."
