Miyu Kouzuki is the main female protagonist of Daa! Daa! Daa!. She was forced to live in the Saionji Temple due to her parents' work for NASA, and lives with Kanata later, as his father left for training in India. She became the Earth mother of Ruu when he arrives.

Miyu is a slim girl with long straight blonde hair in which she sometimes ties in different styles. She often wears casual clothing.

Miyu is shown as an ordinary girl with a kind, generous, motherly personality. She is cheerful, with a ready smile, but also has a soft heart that is easily touched. She feels a deep affection for Ruu.

After Houshou Saionji left the house in their care, she felt nervous living in an unfamiliar place especially together with a boy since it was her first time. After Ruu and Wannya arrive, she felt comfortable living with them as a family. Ruu sees Miyu as her mother and she responds as one to him, knowing how it feels like to be alone.

Miyu often argues with Kanata, but they share a deep bond as they spent time living together with Wannya and Ruu. Together with him, they act as Ruu's parents on Earth.

Ruu calls Miyu "Mama" since she looks similar to his real mother.

Years after Ruu and Wannya have returned to Planet Otto, Miyu and Kanata got married and had a daughter named Miu. Their daughter meets Ruu when she is 12 years old. The story continues in Shin Daa! Daa! Daa!
