Totoyama is Haruki’s and Daisuke’s mother. She was abandoned by the boys’ father after Daisuke was born, and her family is inaccurately rumored to be burakumin. She runs a struggling seamstress shop, but Goro’s patronage soon allows her business to grow and thrive. Mozasu’s wife, Yumi, and Haruki’s wife, Ayame, both work for Totoyama.
