Mrs. Yukino is a minor supporting character in the anime series Queen Millennia. She is the wife of the ramen shop owner who, along with her husband, adopted the extraterrestrial Queen Millennia known as Yayoi Yukino as their daughter. Living above the family-run ramen shop, Mrs. Yukino provides a warm, ordinary home life that contrasts with Yayoi's cosmic mission. Her personality is gentle, nurturing, and motherly; she treats Yayoi with genuine affection and is unaware of her daughter's true extraterrestrial origins and role as the Millennial Queen. Her motivations center on caring for her family and running the shop, offering Yayoi a sense of normalcy on Earth. In the story, she represents the everyday human world that Yayoi grows to love, which become a key factor in Yayoi's decision to protect humanity rather than follow La‑Metal's original plan. Her relationship with Yayoi is that of a loving adoptive mother, and she is also a supportive neighbour to others in the community. Mrs. Yukino has no significant character development or notable abilities; she remains a static, kindly figure throughout the series.
