is a Japanese rock duo founded in 2017 represented by Universal Music Japan. The group is composed of N-buna, a former vocaloid music producer, and Suis, a female vocalist. The duo is extremely secretive, never publicly revealing their faces or holding many concerts. As of date, Yorushika has only held two concerts, one in July 2017 and another in August 2019. [1] The group's music are described as "passionate" and "upbeat", serving as a contrast to the heavier lyrics, which often explore ideas such as love and human emotion and draw from works of literature including Masuji Ibuse and Jules Verne. According to an interview with Natalie, N-buna and Suis met through a common acquaintance; Suis was a longtime fan of N-buna's vocaloid work. Suis first appeared as a guest vocalist during N-buna's two solo concerts in Tokyo. [4][9] N-buna reached out to Suis to form Yorushika as part of N-buna's effort to find a "more human" voice to use in his music, as opposed to vocaloid.[2] Since then, the two have released two extended plays and three full albums, all of which charted on both the Oricon Albums Chart and the Billboard Japan Hot 100 Albums Chart. Yorushika's popularity grew explosively, with critics noting that the lyrics seemed to strike a chord with younger audiences.
