Aruru Otsuki (大月あるる, Ōtsuki Aruru) is a character in the Shōjo☆Kageki Revue Starlight franchise, original to Re:LIVE. She is a first year student from the Stage Expression Course at Frontier School of Arts.

Always smiling with a naturally cheerful disposition, this Stage Girl never lets anything get her down. She was an amateur with no acting experience, but thanks to her earnestness and ability to get people around her involved in things, she is growing rapidly. She is convinced she is blessed with good luck.
