Being born with strange body and peculiar horn, Famura was isolated and exiled by her own people without even understand why. Because of that, she spent her live trying to find a way to be accepted and something that she had in common with others. She found it. She found that everyone has 'bones', the same white bones, no matter what color your skin, your gender, or race. Since that day, she's been obsessed with bones.
Many years passed, her small horn has grown bigger and can't no longer be concealed with his red ribbon. And her obsession with bones and magic has lead her into darker path and brought her into field of forbidden magic.
