Mitama is the daughter of Azama and was raised in her own Deeprealm world, more exactly in a local shrine. Whenever her mother would visit her, she often sang lullabies to Mitama. However, at her young age, she often forgot the melodies and only remembered the words. Mitama's caretakers were shrine priestesses who had a plethora of poetry books, mainly about tanka and haiku. She developed a fascination with crafting haiku in particular. It was noted that her very first haiku was about her mother, though its theme revolved around her longing to see her again.
