Vocal unit CYNHN (pronounced "SWEENY"), means "blue." The group consists of Shiki Ayase, Neru Tsukumo, Tooru Aoyanagi, and Minori Hirose.
Their creative identity revolves around the concept of "blue" (青/Ao), a theme expressed through every aspect of their artistry — from their music and lyrics to their visuals and stage performances. Much of their repertoire has been crafted by songwriter Sho Watanabe, whose lyrics capture "viridian" (碧/Midori,Ao)-tinged yet deeply human emotions that define the group's worldview.
Their sound fuses a contemporary J-Pop foundation with elements of emotional rock, post-rock, and experimental pop. As "The Blue, Unfinished Vocal Unit," they continue to pursue and refine their vocal expression.
