An Osada is Hisako Osada's daughter and murderer. She was the allegedly killed fourth member of Yonagahime 3+1.


An is a petite girl in her twenties. She has straight, dark blue hair that almost reaches her shoulders. She has bright blue eyes and a beautiful face. She has been seen wearing a black and blue dress with black leggings. When she was mourning "Eri Anzai"'s death, she wore a formal, completely black dress. Both dresses reach her knees.



When she was young she dreamed of being a singer and her voice was used to enhance the bands reputation. She tried being a singer later and agreed to be invisible as long as people could listen to her voice but her mother destroyed her dreams because if people analyzed the song it could ruin the bands members later on. This was her motive to have supposedly murdered her mother but that was never confirmed.
