It just so happens that Mistress Fumiko and her husband Haru have a daughter. Yumiko Yureimoto (I'm just using Fumiko's maiden name since Haru's surname isn't mentioned) is the daughter of Mistress Fumiko Yureimoto (a harianago) and Haru (a kappa). Little know fact, during the events of the comic 'Spirits Bloom' when Emiko left the Yokai district, Fumiko and her husband Haru bared a child, whom she was merely 9 months pregnant with. Once Naomi was born she was given Emiko's old room as her own, and her family put all of Emiko's original belongings in a storage place or attic. Granted, Naomi has never met her aunt Emiko before, she was born after she left, but has heard the story of how she left her home to live with a human man. She is polite, sweet, charming, and can be a little shy and mischievous.
