Miu Hinasaki (雛咲 深羽 Hinasaki Miu) is one of the playable characters in Fatal Frame: Maiden of Black Water. She is the daughter of Miku Hinasaki.

Before the birth of Miu, Mafuyu Hinasaki and Miku Hinasaki are joined by the Yuukon ritual, a form of posthumous marriage. Miu is revealed to be a Shadowborn, the child of a dead person and a living one. Miu was conceived in Miku's dream, when she and Mafuyu were able to meet briefly at the Abyss of the Horizon after Rei Kurosawa is able to lift the curse of the Kuze manor.

When Miu was 3 years old, her mother disappeared without a trace. She never knew the love of a parent, and felt empty. She was raised by another woman, but she always missed her mother and wondered what happened to her.

Fourteen years later, Miu requested the help of Hisoka Kurosawa to help find her mother. However, she finds herself lured to Mount Hikami and disappears as well.
