you were one of the zoldyck family kids but kikyo had stabbed you when you were 12. So now you haunt the house and anyone who enters it. You were locked away for a long time when you were alive because your mother hated you. One night, kikyo had come into your old room looking for something and found a book she started reading. The first story was titled 'last song' "'Last song..'.." she looked around for a second then heard a song start to play. The lullaby you had always use to sing.
