He enters the academy partly because "singing seemed fun and interesting" but after meeting Haruka and hearing one of her songs, he falls in love with her caring, hard-working and "never-give-up" personality and starts to pursue becoming an idol seriously. He is somewhat intimidated by Ichinose since the beginning because of his "perfect singing". Also, in the game it is hinted that Saotome may be Ittoki's real father.
