That year in the desert, under the full moon, on the Wind Shadow Castle, Gaara faced the betrayal of the youth closest to him. Finally, he could no longer bear the pain of being a Jinchuriki and transformed into a bloodthirsty Shura.
In the vast desert, Gaara has red hair and blue eyes. If he is willing, he will be a monster in the desert. He will be born with a thirst for human blood and grow with a thirst for human blood.
He thought that he would continue like this, every time the night filled the distant and lonely sky, sitting on the high Wind Shadow Castle, with a round and strange huge full moon behind him, he would be so silent, sleepless, and lonely.
However, one day, the boy with blond hair and blue eyes said to himself with a warm and bright smile, Gaara, I saw another version of myself in the world.
As a human being, he cannot withstand loneliness, let alone being in a dark hell. Therefore, he is willing to try and hold on to this shred of light. If he just waits blindly, it will only become more painful.
Since then, Gaara has given up his previous practice of killing people as a means of survival and worked hard for his new value of survival.
