|“||I have to protect my Family's sword! Have you ever had that kind of responsibility?||”|
—Yu Mira, to Jin Mori during her wedding
Yu Mira (유미라, Yu Mira; "Mira Yu") is one of the three protagonists of The God of High School, and is the 25th Master of the Moon Light Sword Style. She was invited to participate in the God Of High School Tournament. During the World Tournament and RagnarÖk, she received Original Greed and through it Ultio R bequeath her Okhwang's physical power (which he had previously stolen). Due to that, Sang Man-Duk recognized her as the Jade Emperor's successor. In addition, she also received Gáe Bolg from Seo Han-Ryang, 27th Leader of National Assembly of the Homeless, and chosen by the five head 'family' to become the 28th Leader.
Initially, Mira had reddish brown, shoulder-length hair and generally wore round spectacles. She was usually seen wearing a full-sleeved tee along with a mini skirt during and outside of battles. After the time-skip she grew out her hair to the point that it was waist length and wore a black shirt with a red skirt. During the World Tournament, Mira went back to her original hair style and she wore a sleeveless shirt that exposed her midriff with a small black tie to go with it, dark-coloured short shorts with two overlapping straps that held her many swords, dark grey tights and white gloves over her hands; by this point she had stopped wearing her spectacles. Seventeen years after the events of RagnarÖk, Mira's hair has turned white and her face and neck feature small scars from her fight with Ryu but her overall appearance remains the same. She wears an encompassing dark cloak over what appears to be her previous outfit.
By her peers, family, and admirers, Mira is regarded as a beautiful young woman with a great body.
