All their life, they have been put down. Since Birth, they were called Demons. For little Kami didn't have control over her powers, and killed her Parents. Kira protected herself by using her Water like powers, but was given a burn on her back scarring her. They shed tears, but one day they were called The Demons of Fate. For they were the strongest Soldiers the Military ever had, that was until they disappeared. Five years later, when Eren becomes a Soldier, they head out to seek the Twins for they hold the power to Protect their Home. But the Twins aren't fond of regular Humans, making a Village out of people who were like them.
