The eldest and only daughter of the Yoru imperial family, Mafuyu is good-natured, reliable, considerate and academically talented. She seems to have no flaws whatsoever, however this is a facade. She is said to excel in both academics and sports such as archery; hence, people often set high standards for her to excel in everything, which she does without fail. However, in reality she is heavily burdened and pressured by the expectations placed on her by her mother.
