Batako-san works as Uncle Jam's assistant in his bakery, managing essential duties like baking, cleaning, laundry, and delivering bread. She performs critical repairs for Anpanman and fellow heroes, replacing Anpanman's depleted head and mending torn capes to restore their flight. Having witnessed Anpanman's birth in the series premiere, she helped raise him alongside Uncle Jam, forming a familial bond where she acts as a maternal figure. She discovered a stray puppy whom she named Cheese, advocated to keep him, and now interprets his barks during their frequent delivery runs—occasionally joined by Uncle Jam. She maintains positive ties with characters such as Currypanman and Bread Head Man and once sustained a long-distance relationship with Omusubiman, though later narratives leave this unexplored. Physically taller than Uncle Jam, she has rosy cheeks, black eyes, a small round nose, and spiky black hair that shortened over the series. She typically wears blue overalls over a white vest and a chef’s hat concealing her bangs; its removal reveals a bowl-cut hairstyle. Her kind, polite, and optimistic nature shines through her diligent work, with minimal conflict. Beyond baking, her sewing expertise allows her to craft dresses and mend heroes’ capes. Her portrayal remains uniform across all official media, including films like *Sore Ike! Anpanman: Tsumiki Shiro no Himitsu*, without significant character evolution. Her origin—how she met Uncle Jam—is unspecified, though early concept art proposed a discarded backstory of her being found as a baby in the woods by a young Anpanman.
