History
Tsumugi Shirogane is the first child of Hinawa Shirogane and Eichi Shirogane, as well as the elder sibling to Hisao Shirogane and Ayaha Shirogane. From a young age, Tsumugi developed a fixation on television. Her parents, seeing no issue with letting the media keep Tsumugi's attention, neglected her development in favor of letting anime and sitcoms raise Tsumugi. This horribly warped Tsumugi, as she began to see television as a perfect escape from reality.

Tsumugi would often share writing with her brother, Hisao. Hisao enjoyed writing original novels, while Tsumugi wrote scripts. They bonded over this. Meanwhile, Ayaha would joke around with Tsumugi about current events, and they would do school work and play video games together.

Despite her relationship with her siblings, and the lack of one with her parents, Tsumugi was a very unhappy child. She saw herself as a lack of a person, a void where a personality could go. This lead to Tsumugi distancing herself from her personhood, instead perferring to micromanage the personalities of her characters and of those around her. Tsumugi would often play with dolls, basing personalities, conflicts, relationships, arcs, and stories with them as the characters in endless different stories and dramas. Those dolls had more humanity than Tsumugi did. Someone would care about them if they died. Someone would cry at those doll's funerals.But not for Tsumugi.

Tsumugi discovered Danganronpa at a young age, instantly falling in love with it. The characters, arcs, development, and concept were all breathtaking to Tsumugi, who instantly wanted to be a part of it.

Following Ayaha breaking into acting, Tsumugi was ecstatic, wanting her to become a superstar. Ayaha would often joke about acting in one of Tsumugi's shows, though Tsumugi took this as a deadly serious concept, and pushed Ayaha to pursue acting. When Ayaha tried to quit, Tsumugi demanded she continue, telling her that while people are horrible, awful beings, but fans? Fans adore you. Fans will never leave you. If Ayaha wanted to be happy, she would do the only thing she's good at and put on a show. She'd celebrate and dance and sing for her audience until it killed her.

Meanwhile, Hisao and Tsumugi's relationship deterioated. Tsumugi now viewed Hisao's writing as his attempt to one-up her as she pursued writing herself. She began to insult and mock her brother, telling him he would never amount to anything in the writing field.

At age 15, Tsumugi was scouted for Season 52 of Danganronpa, Danganronpa 52: Despair by Daylight. Tsumugi worked as a character designer and intern on Season 52, even auditioning and playing Mei Naotome, the Ultimate Bartender.
