He was an independent musician who made a living through music composition commissions. He was the one who initially inspired Kanade to compose music. When Kanade was in Junior high, her father entered a music competition. Despite his best efforts, he struggled to find satisfaction with his piece. Kanade, seeing this frustration, came up with a section he was lacking, bringing the whole piece together within seconds, to her father's surprise and awe. This song eventually won the competition. However, it was only Kanade's section that earned the attention of the judges. This bothered him, and the feeling only grew as commissioners in the following months only asked for pieces that sounded like Kanade's section, rather than his own work. He became increasingly stressed as he attempted to produce something that sounded similar to Kanade's music. One night, Kanade came into his room, having written a song for him. Upon playing it, her father was shaken, realizing in that moment that his music isn't what modern people need, and that he could never touch the hearts of others with his songs. He then told Kanade to keep creating music, since her music would undoubtedly help people. The next day, Kanade found her father collapsed in his room and unresponsive. At the hospital, the doctors said he collapsed from fatigue, and that he should be able to recover. However, he also suffered from severe burnout, making it difficult for him to remember things properly, without a clear time when he would recover from this psychological damage. Currently, he is still in care at the hospital, slowly recovering from his memory problems

25-ji, Nightcord de., often abbreviated as 25-ji, N25, and Niigo (ニーゴ), is an online music circle that makes songs at 25:00 (1:00 AM). The circle was created by K in hopes of making music that "saves people" and gives them hope. She recruits the members Enanan (Ena Shinonome), Amia (Mizuki Akiyama), and Yuki (Mafuyu Asahina), communicating through a chat tool called "Nightcord." All members were unaware of each other's real names or appearances (excluding Ena, who uploads selfies of herself to the internet, only to be seen by Mizuki) until Chapter 6 of the group's Main Story.
One day, Kanade loses contact with one of her circle members. They find a song file named "Untitled" that is shared with each of them, and upon playing it, they are transported to the Empty SEKAI. In 25-ji, Nightcord de.'s original background setting and the members' introductions, it is mentioned that Kanade approached and recruited all of the members one at a time. Mafuyu joined the group after Kanade found one of her older songs and invited her to work together. After that, Kanade found Ena's art account and came across her illustrations which were based on Kanade's songs, leading to Kanade reaching out to her. A bit later, Mizuki made a video based on one of Kanade's songs and also recorded vocals for it, which culminated in Mizuki joining the group as well.

Mafuyu's SEKAI, the Empty SEKAI, is a dead world containing hardly anything in it. There are a few dim rays of light, broken stage equipment, fallen stage truss, and pyramids that are cold to the touch. These pyramids are said to be Mafuyu's feelings. It is possible to get lost in this SEKAI due to its vastness, as well as how similar the place looks. At a specific location, it reverberates sound differently. It is unsure if this applies to other locations of the SEKAI.

SEKAI (セカイ, World) is a mysterious world separate from the real world. SEKAI are built from emotions, and where VIRTUAL SINGERS live. There are many different SEKAI, each one formed from the feelings of people who are struggling to understand themselves. When the feelings of a person are realized, they will manifest in SEKAI through a song. VIRTUAL SINGERS live in these worlds, with different appearances in each SEKAI, helping people discover their true feelings. People can travel to their SEKAI by playing "Untitled" songs. These songs have no melody or lyrics and are created when a SEKAI is born.
