This is a story of 3 girls from our world that are teleported into the Naruto world. They are also far from ordinary and more close to demons. (The world that the three sisters come from is more like bleach.)
It's a tough world out there, people come and people go.
As for Gaara, people always left.
But soon he had gained someone, someone who cared, someone who he learned to love. And she learned to love him, doing anything she could to protect him. Even if it meant giving up her own life.
