Witch's Bond is a novel (and mini comic) centered around twins. Othella and Sirus have both always wanted to be a witch. A career centered around magic and helping the world for the greater good. The only problem? They are human, and humans don't have a natural affinity to bonds. Humans, as a whole, are so far from the natural and spiritual world, that most are incapable of using bonds.
With that being said, it's not impossible. 
Othella and Sirus are just the ones to prove that. Having the gift of Dark and Light affinity, they want to become just like the Great Witch that defeated a Demon King long ago. 
Join their adventure as they grow, learn, create friendships, and become the witch they always wanted to be.
