Bluebell is the Rain Funeral Wreath and used to own the Rain Mare Ring. With the other Funeral Wreaths, Bluebell reigned over other parallel universes; however, in those universes, they instead faced great misfortunes. However, Byakuran found them and because of their resolution to him, showed them how to become stronger. Bluebell is the only female Funeral Wreath and is possibly the youngest. It is unknown if she is completely human, as she was first seen contained within a tank of water and can make her own body parts change into water. Bluebell has a childish personality similar to Byakuran; though, despite her appearance of being around 10 years old, she also seems to have a very sharp tongue. (Source: RebornWiki)
