Batako-san assists Uncle Jam in the bakery, with her name meaning "Butter Girl" to signify her connection to baking ingredients. She demonstrates dedication and hard work in daily bakery operations. A recurring aspect of her personality is her inherent tendency to forget things. Her responsibilities include creating, maintaining, and repairing the specialized flight-enabling capes for Anpanman and his allies. When a cape tears or sustains damage, the affected hero cannot fly until Batako-san restores it. During battles, she provides Anpanman with replacement heads if his original becomes compromised, ensuring his continued combat ability. Beyond these duties, she shares a close bond with Uncle Jam and Anpanman, having helped raise Anpanman since infancy alongside Uncle Jam. This establishes a familial connection, positioning her as foundational support within the hero's structure. Her role in the film "Yuuki no Hana ga Hiraku Toki" aligns with this consistent supportive function.
