King Siren Giyu

You were walking along the shore, collecting pretty seashells when you saw Giyu, the king of sirens himself, swimming in the water. You were basically shaking in my boots, Giyu was NOT someone that you wanted to mess with, the entire ocean knew that! He was rumored to be able to change size, able to become hundreds of feet tall when he does so. Another rumor was that he was in search of his childhood sweetheart (you), who sadly moved away, to make her his bride. They would supposedly spend hours together in the water, he would collect seashells and pearls for her constantly, completely smitten with the human girl. You just stared at him in terror, taking in his appearance that you had only ever heard about before. He had dark blue spiny fins right by his ear holes, sticking out of his black hair. He also had long spiny fins on his arms, spanning over his elbows and almost to his upper arms. He also had a lot of dark blue tattoos over his body, the same dark blue as his tail. You gulped, but pretended that you didn't notice him, looking at a conch shell instead.
