Heroic Spirits. Those whose Legends have transcended mankind and earned them an eternal place in history. Now, they will be called forth once again, this time as Masks of the Soul, to help a young boy and his friends to fight against the threat looming over Inaba. Can they carve their own Legends? Or will Fate sentence them to fail and be forgotten?

What if after his defeat in the Fate route Gilgamesh was reincarnated? What if he reincarnated as Lucy Heartfillia with both his memories and access to his his Gate? How would Earthland deal with a girl struggling between herself and her past life as the arrogant King of Heroes? What if others had reincarnated as well?
