Roro Morooka is a character in Ongaku Shoujo. She is a member of the idol group of the same name. Despite looking 10, Roro is actually 18! She was raised by her grandmother, so her likes and things she knows are a bit old-fashioned. When she catches a cold, she wraps a green onion around her neck and puts umeboshi skin on her forehead.

Ongaku Shoujo
There are eleven girls that consist the C-class Ongaku Shoujo idol unit under Pine Records. Despite generating red sales marks and not being very popular, Producer Ikebashi and the members are trying their very best to up their levels. Nevertheless, Ikebashi suggests recruiting a new member for Ongaku Shoujo; someone who can act as a catalyst for the success of the group. Thus, an audition was opened, leading to the soon-to-be legendary group's meeting to a girl named Hanako.
