Közi is a Japanese visual kei rock musician who plays guitar, piano, keyboard and synthesizer. He is best known as guitarist for the rock band Malice Mizer. After the band went on an indefinite hiatus in 2001, he formed the industrial rock duo Eve of Destiny and also started a solo career. As of 2012, Közi is in the bands Dalle, My Horror Revue, XA-VAT and ZIZ, while occasionally working on his solo career.During his time in Malice Mizer, Közi often assumed the role of a pierrot doll, dressing in clown-like costumes with large ruffs, always in shades of red, his favourite colour. In music videos and on-stage he would often make movements reminiscent of a marionette (string puppet). Közi has continued this visual style to some extent, but his contemporary stage costumes are more gothic. His work on the Izayoi no Tsuki project was reminiscent of carnival music, and artwork for his projects usually follow a dramatic, theatrical theme. Very few details about his private life are known.
