Yasuko Takasu

Yasuko is [Ryuuji](https://anilist.co/character/12295)'s thirty-three-year-old mother, though she refers to herself as eternally twenty-three. Soon after Ryūji was born, her husband died which left her to raise her son by herself. She works at a hostess bar named Bishamonten Kuni where she goes by the name "Mirano" and single-handedly supports her two-member family financially. However, she has a childish personality and since she works, she entrusts the household chores to Ryuuji. She instantly takes a liking to [Taiga](https://anilist.co/character/12064) and already regards her as a member of her family. (Source: Wikipedia)
