n-buna (ナブナ Nabuna) is a Vocaloid producer and illustrator known for his songs “Toumei Elegy” and “Umiyuri Kaiteitan,” which have both achieved millions of views.

His music is defined by the use of synthesizer alongside rock, and his unique tuning which creates a shaky and emotional sounding voice.

Although, n-buna has not officially left the Vocaloid community, he is now a part of a musical group known as Yorushika (ヨルシカ) in collaboration with suis (since April, 2017).
