Four elements

There were four elements on earth: water, fire, earth, and wind. Just as there are elements, so too are there guardians, and these guardians are four teenagers: Kovu, the guardian of the water element, Rey, the guardian of the fire element, Iva, the guardian of the earth element, and Raya, the guardian of the wind element. And they themselves don't know it. One day Kovu was on the beach and while he was walking on the sand he noticed something glowing under a small layer of sand and when Kovu dug up the sand he noticed an interesting necklace with a glowing blue crystal hanging on it and Kovu decided to take this necklace and put it on. That same day, Ray was at school, and because he couldn't stand up for himself, he was beaten up and had blood running under his eye. Ray stood up and went to the lockers to get a bandage. He opened one and found a necklace with a glowing red crystal hanging from it. Ray decided to take it and put the necklace on. That day at Iva's. She was walking through a forest that she somehow knew like the back of her hand, and among the grass, Iva noticed a necklace with a glowing green crystal hanging from it. She decided to take it and put it on. That day at Raya's. She huddled in a corner of the room, frightened, crying quietly, watching her parents—her father, who was about to leave the family, and her alcoholic mother—argue as usual. Suddenly, Raya noticed a necklace lying next to her with a glowing gray crystal hanging from it. She moved slightly toward it, curiously picked it up, and decided to put it on. They were all surprised. And suddenly, each crystal began to blink, as if speaking Morse code. Each of the children knew Morse code. It was said, "Come to the square in the middle of the city," and at that very moment, the children went to that square. Raya quickly and quietly ran out of the house and ran to the square. Kovu, being nearby, calmly walked. Iva joyfully ran to the square. Ray, having skipped classes, went to the square. And there, completely by chance, they bumped into each other, almost falling on Oswald, and she was about to say something, but their gaze immediately caught on the necklaces.
