Background / History

Mahiru lived alone in apartment 502 in Fuchu City. Her biological parents provided for her daily needs but neglected her emotionally, leaving her to question why they did not love her despite her efforts to be “cute.” 30 97

She first met Sakurakoji Talent while he was disguised as Ogura Asahi, a young woman who offered her dessert and comfort in a park. Mahiru quickly became attached to Asahi, inviting her home and fearing that their parting meant they might never meet again. 30

At her graduation ceremony, Mahiru introduced Asahi as the unrelated sister she had met outside her family. Asahi attended the ceremony and gave her a personally designed and made dress, which Mahiru treasured deeply. 43

After learning more about Mahiru’s neglectful home life, Asahi offered to bring her into the Sakurakoji/Okura family as an adopted sister and protect her from her parents. Mahiru eventually accepted the offer. 97 She later entered Seijo High School as the top scorer on its entrance examination. 94

Following her entrance ceremony, Talent arranged for Mahiru to live in a villa near Seijo High School in Fuchu City, with Miss Tachikawa assigned to assist her. Although Talent considers the Sakurakoji/Okura residence her true home, Mahiru continues to live independently at the villa for the convenience of attending school. 215

Mahiru eventually met Asahi’s relatives, including Sakurakoji Ashiri and Okura Rumin, and was formally welcomed by Sakurakoji Luna and Okura Yusei as part of the family. 264 313 315

Her relationship with Asahi was shaken when she learned that “Ogura Asahi” was Sakurakoji Talent’s female disguise. After struggling with the revelation, Mahiru accepted that he remained the same person who had supported her and resumed calling him Sister Asahi. 265 282 She later confessed that her feelings for both Asahi and Talent went beyond a sibling bond, beginning a romantic relationship with him. 285 286

Rather than move to Tokyo or transfer schools solely to stay closer to Talent, Mahiru resolved to remain at Seijo and become more capable in her own right. She has increased her studies and enrolled in additional enrichment classes so that she can one day be useful to the Sakurakoji/Okura family. 531

Appearance

Mahiru is a petite, delicately built girl with a doll-like appearance. She has flaxen hair, caramel-colored eyes, fair skin, and a refined presence that draws attention at school. 110 215 217

• Often described as exceptionally cute and beautiful by those around her. 30 215
• Maintains silky, well-cared-for hair. 94
• Wore a pure white dress while waiting for Asahi. 215
• Wore an elaborate azure-and-blue floral gown with a small crown headband at a formal gathering. 559
• Her peers associate her with the “Angel” reputation surrounding Asahi. 111 215

Personality

Mahiru initially appears shy, timid, and deeply insecure about whether she deserves affection. She is easily moved by sincere care, especially Asahi’s handmade gifts, cooking, and repeated assurances that she belongs with the family. 30 43 96

Despite this softness, Mahiru is not helpless. Before relying on Asahi, she had lived independently for years and cultivated a composed “perfect young lady” persona in public. When expressing what she truly wants, she can be remarkably firm and courageous. 286

She is earnest, polite, and highly conscious of etiquette, sometimes bowing so deeply that she embarrasses herself. Her attempts at retaliation or mischief are notably gentle, such as adding an extra tea bag or preparing snacks for Asahi. 95 264 313

Mahiru tends to compare herself unfavorably with Ashiri, Rumin, and Asahi, believing she has little to offer them beyond academic effort. She wants to attend a Tokyo university so she can support her new family in the future. 283 284

Although she remains modest about her place among Talent’s unusually gifted relatives and companions, Mahiru has become more independent and ambitious. She chooses long-term self-improvement over simply remaining at Talent’s side and is determined to prove that she can contribute to the family. 531

Mahiru has also grown more playful around people she trusts. She teases Ai about her relationship with Talent, while still showing sensitivity toward Rumin and apologizing when she believes their behavior has caused Rumin distress. 832 835
