Sagami, Rei

Rei serves as Sana's manager.

Spoiler

Sana labels him her "pimp" after reading a book containing the word, though she does not grasp its true meaning. Additionally, Sana considers Rei to be her boyfriend. Later, Akito informs Sana that Rei is merely playing with her, viewing her simply as a little girl wanting to play. Misako also tells Sana that Rei cannot be her boyfriend. This leaves Sana devastated. But after she gets over her heartbreak, Rei remains her manager and her friend.
