Background / History

Mahiru is the Shiina Family head's second granddaughter. Although she was considered decently talented in every area, her cousin Shiina Mashiro's extraordinary artistic success caused Mahiru to be unfavorably compared with her from childhood. Her mother's resentment and her father's neglect left Mahiru meek, humble, and desperate for approval. 228

Despite this upbringing, Mahiru excelled academically. Her school awarded her a monthly living allowance of 118,000 yen and waived her tuition after she placed first in her studies. Her mother later took Mahiru's savings, accused her of immoral behavior, and expelled her from the apartment Mahiru had been paying for. 229

While homeless during a rainstorm, Mahiru encountered Akasaka Ryunosuke. Moved by his kindness despite his own circumstances, she took him into her home and began caring for him. Their initially sibling-like arrangement became romantic after Akasaka nursed her through a cold and handled the household work in her place. Mahiru eventually proposed to him, and the two secretly registered their marriage. 229 230

After Akasaka disappeared, Mahiru remained in their old apartment because she feared he would be unable to find her if she moved. Her despair became severe enough that Sakata Gintoki, Shimura Shinpachi, and Kagura stayed close to prevent her from harming herself. 467

Akasaka recovered his memories of Mahiru after seeing an old photograph of her with Shiina Hiyori and immediately sought her out, remorseful that she had waited for him for roughly a year and a half. 481 482

Mahiru's mother had originally been married into the Vongola Family as part of an alliance arranged by the Shiina Family head. After her father Iemitsu Sawada abandoned the marriage for another woman and son, Mahiru's mother redirected her resentment toward Mahiru and eventually abandoned her as well. 915 917

Wanting to secure a future for her child, Mahiru returned to the Vongola Family despite her painful history with it. Timoteo, the Vongola Ninth, welcomed her back and arranged for Reborn to train her as his successor. 915 917 924

After the Ring War, Mahiru left Japan for Italy with her child, Ai Hayasaka, Hayasaka's daughter, and Kagura in order to establish herself at Vongola headquarters. She subsequently received the Ninth's investiture and officially became the tenth-generation Vongola Boss. 992 997

Appearance

Mahiru is recognizable by her long, straight flaxen hair and distinctive amber eyes. 467 481

• Often wears a pink apron while cooking in the home she shares with Akasaka. 467
• Her daughter Shiina Mahane resembles her closely, including her amber eyes and hair color. 958
• At her Vongola investiture, she wears a conservative black mafia suit with black trousers and a red tie. 997

Personality

Mahiru is fundamentally gentle, considerate, and self-reliant. She continued studying at home after pausing her education because of marriage and pregnancy, and she had previously ranked first in every subject. Unlike her cousins, she is capable of managing housework due to the hardships of her upbringing. 703 791

She treats Ai Hayasaka and Nao Hayasaka as members of the household rather than servants, allowing them to eat at the same table and ensuring they are not overworked. 740 909

Her abandonment trauma makes her intensely fearful of losing Akasaka. When she learns of his other relationships, she becomes cold, possessive, and confrontational; she struggles to accept polygamy despite eventually accepting Hiyori. 486 797 903 909 Her anger can be intimidating enough to silence Akasaka and frighten Yui. 879 907

Mahiru's kindness also extends to those Akasaka brings under her protection. She accepts Chrome Dokuro as a younger sister and reassures her that she belongs to the family. 956

As Vongola Boss, Mahiru displays practical judgment and a growing sense of responsibility. She brings trusted caretakers to Italy, intends to build a dependable inner circle, and identifies Kagura as a potential Guardian. 992 Her future self is notably calm and tactically composed under VSXANXUS's artillery assault, reflecting the confidence she gains as Vongola leader. 989
