same but completely opposite (garra×oc love story)

Right before the chunin exams two new villages were discovered, the village hidden in the sound and the village hidden in the elements. The village hidden in the elements is far different from all the other villages, some things make it stand out from the rest like that facts that no one's heard of them before, secondly they're on an island far past the hidden mist village, 3rd they only produce 3 Ninja every 20 years. But that's not all, the most shocking news of all is that they have 3 demons as strong as the 9 tailed beast. As the years went on they didn't need an alliance with anyone else but as the numbers of Islanders where slowly diminishing they needed a way to keep their legacy alive. So 3 Ninja are decided to go to the village, but there's a catch all 3 Ninja are the demons, oh but there's more these are children of the village leader. Mizuko(water Ninja), Daichi(earth Ninja), and Kasai(fire Ninja) are the 3 demon Ninja of the element. Mizuko is the strongest Ninja in her village along with her two brothers, Daichi the second strongest, and Kasai the third strongest. All of them living hard lifes, they're cold anyone and everyone. But what happens if they meet two other people like them.
