Sakura Akiyama is the mother of Asuka and Miku Akiyama, serving as their primary caretaker while her husband remains abroad on a long-term business trip. She embodies the Yamato Nadeshiko ideal, often wearing a kimono at home while upholding traditional domestic practices. Her weekly routine includes teaching flower arrangement classes from her residence.

Physically, she possesses gray eyes and gray hair, typically fastened in a waist-length ponytail using a hair tube, with a distinguishing mole on her face. Her stable family life fractures when intruders target her daughter Asuka for humiliation, invading their home to exploit Sakura's vulnerability during her husband's absence.

In the sequel narrative, her family confronts heightened brutality. After Asuka's marriage to Ryosuke, a criminal group abducts the entire family. Sakura, Asuka, and Miku suffer gang rape and forced sexual slavery, emphasizing her role as a victim within a cycle of exploitation targeting the family. The documented materials do not depict Sakura shielding or supporting her daughters during captivity. Secondary plot threads involve Sakura and Miku attempting to attract Ryosuke’s attention before their abduction, actions that precipitate their capture by other antagonists.

Sakura’s character arc concludes with minor appearances alongside Asuka in certain endings; her post-sequel fate and status remain unspecified.
