Yukari Otomi (音海 紫 Otomi Yukari?) is a biologist of Mainland, mother of Mayura Otomi and the wife of Seigen Amawaka.
Yukari has yellow and green long, wavy hair and blue eyes, with the usually smiling face. She heavily resembles her daughter, Mayura.
She is caring, curious and stubborn. Those are shown while she smuggled to the Tsuchimikado Island, investigating her brother's death and took a part in Seigen's daily life. She can be very scary at times - even Seigen stated that she is more dangerous than impurities after she got furious during a family meeting with him regarding Mayura and her abilities.
Yukari was born on the Mainland where she was spoiled by her father Zenkichi Otomi and her older brother, Otomi Satoshi. At the age of 23, her brother Satoshi managed to see her before he was to be executed for being cursed. The executer Seigen Amawaka tried to hypnosis her but failed, and she decided to find out the truth and meet him after that. They fell in love, married and lived in the island for years, but one day Seigen decided to drive her out of danger by separating with her. Yukari found her pregnant with Mayura three months after coming back to the Mainland.
Sometime she and Seigen divorced but despite this she still cares very much for him as she and Mayura know that he left to protect them from danger. They are possibly remarried after Seigen retired from the Twelve Guardians, as depicted in the author's Twitter.
