Nogizaka Haruka no Himitsu (乃木坂春香の秘密, lit. Haruka Nogizaka’s Secret) is a Japanese light novel series by Yūsaku Igarashi, with illustrations by Shaa. An anime adaptation produced by Studio Barcelona aired between July and September 2008; a second anime season aired between October and December 2009.
The story is set at the private high school Hakujō Academy in Japan and centers around Yūto Ayase and his classmate Haruka Nogizaka. While Yūto is rather ordinary, Haruka is very attractive, intelligent, and rich. Due to this, she is the school’s most unattainable girl and is so idolized by her schoolmates. One day, Yūto’s good friend Nobunaga Asakura asks him to return a book to the school library, and when he goes to return it, Yūto stumbles across Haruka and her darkest secret—she is a diehard fan of anime, manga, and the otaku culture. Yūto promises to keep her secret hidden, since her hobby is considered unworthy of her status, and the two become close friends and start spending much of their time together. Yūto does his best to help hide Haruka’s secret hobby while further developing his relationship with her.
