Profile

They have been familiar with piano since their’s childhood. They started playing in a band in high school, playing drums and keyboards. Hatsune Miku” was once a topic of conversation at the company where They worked, but since They liked instrumental music, They was not interested in it at the time. Later, They became ill and was unable to play an instrument properly, which also affected Their’s interest in singing things. It was the VOCALOIDs Hatsune Miku, Kagamine Rin, and Len that gave Them hope to continue with music. They like various genres. They have been composing music since They was a student, but VOCALOID is the first time They have publicly shared Their’s work. It was also the first time for Them to write lyrics for VOCALOID. It was also Them first attempt at a video under a different name(Tappo).

From childhood, They had a frail constitution, living each day as if poor health were the norm.
Wanting to be even a little stronger, They devoted Theirself to sports during Their student years to build Their body. Influenced by Their mother, who loved singing, They adored music from a young age.
A friend’s invitation led Them to start playing drums in high school and begin band activities.
Later, aiming for a professional career, They moved to Tokyo and pursued band activities in the city. They have a history of winning contests.
Life was fulfilling, but a few years later, a mysterious symptom struck: They suddenly lost all grip strength and could no longer hold drumsticks. Then, as if to compound the blow, a serious illness was diagnosed, forcing Them to abandon Their dreams. They tried giving up music and returning to an ordinary life, but it felt like a gaping hole had opened in Their heart. Everything lost its color, and They suffered for a long time from the sense of loss, as if They’d lost something precious.
Amidst this, They resolved to challenge the world of music once more, forming a unit with mirun and stepping back into the musical realm.
Later, They took on illustration despite having no prior experience. Having always loved singing and being quite particular about it, They also challenged Theirself with Vocaloid voice tuning.
