Description
Mahiru Sakai is the late mother of Wakana Sakai and the wife of Keisuke Sakai, having passed away just before her daughter was set to begin high school. Her birth date is noted as May 15th. She is a figure whose influence permeates the entire narrative, even in her absence, as her life and death serve as a catalyst for her daughter's emotional journey and, by extension, the formation of the central choral club.

In terms of appearance, Mahiru shared a strong resemblance to her daughter, Wakana. Both are depicted with black hair, typically tied in a ponytail, and brown eyes. The primary distinctions are that Mahiru had slightly longer hair with straight, square bangs, whereas her daughter's hair is a bit shorter with multiple strands framing her face.

Her personality is described as easy-going, cheerful, and always inclined to see the positive side of things. She was an open and affectionate person who shared a deep and playful relationship with her daughter when Wakana was young. This warm and spirited nature extended to her friendships, most notably with her high school classmate Naoko Takakura. Her fundamental belief about music was that it should be fun and serve as a means to bring people together and convey feelings, a philosophy that contrasted with the more rigid views held by others.

As a student at Shirahamazaka High School, Mahiru was a member of the original choir club, alongside her best friend Naoko Takakura and Shiho Okita, who is the mother of Sawa Okita. Her talent was so significant that Naoko later describes Mahiru as having single-handedly defined the choir club and its music during their era. Her creative abilities extended beyond performance, as she was a songwriter who penned the song Amigo Amigo, which became a hit for the fictional musical duo Condor Queens and is a favorite of Konatsu Miyamoto.

The central motivation that defines her posthumous role in the story is a promise she made to her daughter: to write a song together. Before her death, Mahiru had begun composing a piece with the hopeful aspiration of finishing it with Wakana. However, as her daughter grew older, she became more distant, and Wakana turned down the offer to collaborate. Mahiru continued to work on the song until her illness prevented her from finishing it. This unfinished song, a symbol of their fractured bond, is discovered by Wakana later, and completing it becomes a crucial step in the protagonist's healing process.

Mahiru's role in the story is that of a beloved memory and a source of lingering grief. Her untimely death from illness left a profound emotional wound in her daughter, causing Wakana to abandon music and become withdrawn. The entire narrative of Tari Tari revolves around the main characters, particularly Wakana, coming to terms with their personal struggles, and Mahiru’s legacy is the emotional core of this process. Her friends from high school, Naoko and Shiho, are also deeply affected by her loss, with the former struggling to reconcile her fond memories of Mahiru with her own strict approach to music education.

The character of Mahiru does not undergo development herself, as she exists only in flashbacks. Instead, her development is felt through the evolution of her legacy. What begins as a source of pain and regret for Wakana gradually transforms into a source of inspiration and connection. As Wakana learns more about her mother's impact on others and the joyous spirit with which she approached music, she is able to move past her grief and embrace her mother's dream, ultimately completing the song under the title Radiant Melody.

Her notable abilities included singing, playing the piano, and songwriting. Her talent was remarkable enough to be remembered by her peers and to have produced a professional hit song. More importantly, her most significant ability was her profound, intangible impact on the people around her, using music as a vehicle for her warmth, joy, and love, which continued to resonate long after she was gone.
