Renge was a tall and beautiful, young woman, with long, dark strawberry blond hair that reached her shoulders. She had whitish, tanned skin and had the same cool light, blue eyes as her sons. Her appearance overall greatly resembled that of her youngest son, Ren.
Renge was a famous idol that was known throughout the world. She died relatively young in an accident sometime after her youngest son, Ren was born. After dying, her husband, in his grief, discarded every item of Renge that was in the house. Because he could only see his mother's face through recorded videotapes of her performances, Ren would watch it whenever he felt lonely. During one of these periods, Renge's husband discovered Ren with the video and immediately disposed of it. Some point after this, Ren found an mp3 of his mother singing a song to her then unborn baby, which Ren would listen to every time he went running to the park upset.
