In the MHA Fantasy AU, Eri is the surrogate daughter of Shota Aizawa. Though she lives at Yuuei Guild now, she often visits the Unicorn Meadow where she used to live because her mother abandoned her after she accidentally rewound her father out of existence, leaving her all alone. She was Rewind Magic, and was blessed by a unicorn before she was born when her mother touched the unicorn’s horn. She has a small horn on the side of her forehead.
