Amane Ubuyashiki is the wife and caretaker of Kagaya Ubuyashiki and the mother of Hinaki Ubuyashiki, Nichika Ubuyashiki, Kiriya Ubuyashiki, Kanata Ubuyashiki and Kuina Ubuyashiki. Her maiden name is Amane Himorogi. Amane is a fair woman with pale skin and large, lavender eyes and short eyebrows. She wears her white-colored right-swept hair in a short ponytail with two strands of hair let loose at the front. Amane wears a salmon-colored mofuku kimono with an ombre to orange at the top with flower patterns with a dark-indigo haori with numerous blue butterfly-patterns. She also wore a brown with a paler shade striped-obi with an orange obiage supporting it. Amane is shown to possess the same quiet, strict and serious disposition as her husband and children, acting professionally and tactfully when communicating with the Hashira during her time filling in for husband when his health began to fail. She is shown to be just as devoted to the Demon Slayer Corps as her husband and children as well, and spared no time in trying to figure out anything that could be used to turn the tide of battle in to their favor. As well as this, Amane has been shown to truly love and care for her husband, Kagaya Ubuyashiki, and is seen constantly nursing him and staying by his side as his body slowly began to fail and his health further worsened. In fact, the only time Amane dropped her usual controlled demeanor was when Kagaya's health began to severely plummet and he began to cough out blood, causing her to immediately panic and worry as she barked out orders for her children to help her treat him, showing a genuine sense of love between them. Later, upon Kagaya reaching the end of his life and being approached by Muzan, Amane chose to stay by his side and commit suicide via bombing in order to die together with him and severely injure Muzan at the same time, fully showcasing her immense devotion to both her husband and the Demon Slayer Corps. Amane was also noted to have been a loving, caring and strict parent to her children, making sure to raise them to be independent and emotionally strong in order to prepare them for her and her husband's inevitable deaths. She showed a strong amount of faith and love towards her children and their potentials.
