There once were many villages of magical beings, all kind and unique in their own ways. They were all living in a secret harmony among humans. Witches were born from a beautiful flower, The blue spider lily. They were created to erraticate demons and guard human life, Vouching to never hurt any humans. Until disaster struck, It started with thousands of magic users homes being burned down by fearful and power hungry men. Than many were slaughtered, hung, or burnt at stakes. Soon some witches gave up on being good, and protecting humans. Turning their back to humanity, Leading them to be called the dark witches who kidnapped people and ate them for their ancestors revenge, The cruel world had driven the rest of the population into hiding, dwindling numbers had lead the good witches bloodline to almost go extinct. Eventually witch genes had become a recessive trait.

And of course little unlucky Giyuu had to be one of the few.
