Fifteen years ago, his mother died in a plane crash, resulting in him having to be brought in at an orphanage. Also, he has never "met" his father, who is in fact Shining Saotome. His adoptive mother, who is a Christian, also gave him a rosary that he keeps with him. There is also rumour that Cecil is his younger brother.
Haruka's classmate in A Class. He's a friendly and positive person who enjoys singing. He shares a room with Tokiya from Class S. In the anime, he stands up for Haruka when she was barred from taking the entrance exam due to being late. He enters the Academy partly because "singing seemed fun and interesting" but after meeting Haruka & 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".
