Ouji is a third-year student at Private Aria Academy and basically the definition of the school idol. He leads a group called the Musical Princes, which has made him pretty much the most popular guy on campus—especially with the girls. Kanade's had a crush on him for a while, and Ellen ended up developing feelings for him too.
He's a huge fan of Maria Hojo, Hibiki's mom, which puts him in good company since most of Hibiki's classmates are into her as well.
