There is still no official background for Saber Lily, but another fan speculation states this is how Saber would probably look is she never had to hide her gender when she was alive. In Battle Moon Wars, this was how Saber looked when she was Kohaku’s Servant.I think Saber Lily is still Saber, but it would be nice if there was some background story for her too like Dark Saber. Thanks to Belia for sending this!
