Being a part of the Vocaloid music circle, 夜鳴夜叉 (Yonaki Yasha) participated in numerous group such as Demonoa, Fade Into Color and Rice Records, though unfortunately, Fade Into Color isn't active any more. His expertise lies in making genre such as metalcore, post-hardcore and sometimes, assembled a deathcore music from time to time. He also bear a different name called Ashay, which make difference from this alias as he barely used a Vocaloid voice while producing music as Ashay and usually sang with his own voice.
