Granny is the elderly caretaker of the protagonist, Nio, in Blue Miburo. She runs a small dango shop, a type of rice dumpling eating establishment, where she lives and works alongside Nio and a young girl he refers to as his sister. Neither of the children she cares for is related to her by blood; instead, she has taken in the orphaned Nio and the sister figure as her own family. Her primary role in the story is that of Nio’s guardian and the proprietor of the home that serves as the series’ early setting. Her background indicates she is a kind-hearted individual who provides a stable, if modest, livelihood for the children under her care in Kyoto during the tumultuous Bakumatsu period. While no notable combat abilities or significant character development arc are detailed, her presence establishes the personal stakes and moral foundation for Nio, who is driven by a strong sense of justice he likely learned from her. Information regarding her specific personality traits, motivations, and further relationships is not available.
