B Gata H Kei -

, also known as Yamada's First Time , is a high school romantic comedy series that originally started as a four-panel manga by Yōko Sanri. It follows Yamada, a beautiful but hilariously misguided 15-year-old girl who enters high school with a single, extreme goal: to have casual relations with 100 different men.

Despite her bold aspirations, Yamada is a panicky virgin with significant social anxiety and a fear that she looks "strange". To overcome her mental barrier, she chooses her plain, shy classmate Takashi Kosuda as her "cherry boy" target—an inexperienced partner she believes won't judge her.
