She is Junna's roommate, and at the same time, a Stage Girl with extraordinary talent in both performing and stage creation. She often has the chance to bake together with Mahiru, and she is affectionately nicknamed "Banana". She loves everyone who helps to create the stage together, and that is the reason why she sometimes shows a ruthless side.
