The Kreats.
Half cat, half human.
At first, all that Anna knows about them is that they're different from regular humans...and their fights.
'Bond' fights, as they call them.
What are they, she wonders? And why are they dangerous to humans?
She didn't know why, until...he comes along.
Sora. A Kreat amongst an all-human school. Sora, who's a loner by nature, and who doesn't want to get close to Anna at any cost. 'The danger'...he tells her.
But when Anna unwillingly gets pulled into his fascinating world of Kreats and bond-fights, she develops an unnatural bond with him. Why is Sora so distant? What could have happened in his past to make him that way?
