"Yumekake Uta", featuring KAITO, is the 13th original work of Intro-P's. It is a slow-paced traditional song, also featuring Intro-P on backvocals. According to the author's comment, the song was composed when Intro-P came across with KOSU's illustration on piapro, and decided to dedicate a song for it. The said illustration is also featured in the video. This song is featured in Intro-P's album, Introduce My Love. It has entered the Hall of Fame.
