Naozumi Kamura

Naozumi, like Sana; is a child actor who is very famous. He and Sana meet by making a commercial together. Naozumi comes from the Kamura Institute, which is why he knows about Sana's secret past. While he tries to do many noble things for the sake of Sana, he seems to plot them in a rather... scheming way.

Things start to get mixed up once he and Akito meet. Akito obviously likes Sana, and Naozumi has been a fan of Sana's since he (and she) were little. Akito and Naozumi become rivals who sort of compete for Sana, although in totally different ways. Naozumi also has a habit of playing a trumpet extremely loud when he gets frustrated, much to the dismay of his manager.
