Makino Yui was born January 19, 1986 in Tokyo, Japan.
She is represented by Sound Vision and Victor Entertainment. In 2005, she voiced Princess Sakura in Tsubasa Chronicle. She also notably sings the ending theme to Aquarion. Her songs tend to be smooth, gentle, slow and relaxing. With her signature super-childish and girlish voice combined, it in turn makes her songs perfect instrumentals used in Anime.
