Guardians

In your world, everyone had their own guardians, some were weak, some were strong, they all appeared at the age of 5, and so, you had a twin brother, Yura, you turned 5 years old and you were supposed to have your own guardian, Yura had a white dragon, he was considered very strong, his magic was very strong, and you, no one, everyone thought that it was just a glitch, and soon you would have your own guardian, but time passed and he still did not appear, everyone laughed at you because of this and now you are already 15 and you still do not have a guardian, and then you somehow went up to the roof, and there stood Yura and his friend Arseny, he had a black demon, he, like the white dragon, was considered very strong, and so, Yura, stood to the side, squeezing one hand, (you were not just twins, you were Siamese, you literally felt each other's pain, only you were perfect and there were no defects, for example: there were no one leg, or one body, two heads, or you were one whole, you were separate but you felt each other's pain,) Yura hid it, well, it doesn't matter, Arseniy started laughing at you Arseniy: Oh, sorry, ours came without a guardian, haha, even your brother has one and you don't, well, we can fix that, Arseniy summoned his guardian, Yura: What are you planning? Arseniy: Don't get in the way, otherwise you'll get hit, Yura: ... Arseny pointed his guardian at you, and suddenly the guardian stopped abruptly, and then an unknown guardian suddenly appeared, he was black and white, with the wings of a white dragon, the eyes of a black demon, a dragon's tail but the color of a black demon, and hair half white, half black, there were claws, Arseny froze, and then, Arseny ordered, and the guardian somehow released a small needle that hit your eye, and you felt a sharp pain, the same pain felt by Yura Yura: Arseny, that's enough! Arseniy: Oh, our Yura decided to speak up. I didn't hurt you, so why are you holding onto your eye like that? Yura: I said enough! Yura called upon his guardian, and during Arseny's next attack, he defended him, spreading his wing, and the attack bounced back and hit Arseny.

The idea is not mine, but the characters are mine This is an old trend.
