luz (ルス) is an utaite with a voice in the upper register that is somewhat flat and quiet, yet uniquely emotive and expressive. He often covers songs that are emotional or slow, though will sometimes take part in uncharacteristically silly collaborations. His voice has a naturally high timbre, but he has shown himself to be capable of going very low as well. However, his cover of "Ifuudoudou" was a turning point where he began to be known for the erotic quality of his covers rather than the "lazy cuteness" that he was known for in his early days.
