By the time Yami reached the beach the sun had set once again. The moon was still full for the most part and it provided good light for him to swim by. He stripped off his clothes and walked into the surf. He allowed the water to wash over him as he floated on his back. The water cooled and soothed his injuries.
See? He thought to himself, There's nothing here. And I'm not crazy.
He submerged himself fully and felt himself consumed by the sea. It sealed him away from the world and he hung in what felt like suspended animation. It relaxed and purified him. It was the definition of silence which could only be found here, in his eden, the ocean.
He cracked open his eyes below the water and a flash of purple cut across his vision. It had been shiny. Like fish scales? Yami thought. It was certainly a large fish! If I catch it it could feed us all! Giving no thought to the fact that he did not have any fishing gear, he chased after the shimmering figure.
It was lucky enough that he had seen it in the first place. Predator and prey were swimming about five feet below the water, so it was pretty dark. Ocasionally a cloud would cover the moon and Yami would lose sight of it completely. But it would always appear about where it had been before when the light from the moon returned.
It's strange, He thought, surely a fish of this size could've easily outswam me by now. It almost seemed to be taunting him. Going slow enough for him to keep up but never catch up. Like this was some sort of game. And I never lose a game! Yami thought. He noticed they were getting closer the the rock pool where he had been sitting last night. A plan formed in his mind. I can outsmart a stupid fish, he thought arrogantly. He grabbed a quick breath of air and resubmerged.
He grabbed a medium sized rock off the bottom and continued his pursuit. Once the fish had moved into the pool Yami sprung his trap. The rock pool had only two escape routes, out around the outcrop of rock where he had sat last night and another off to the side. Yami noticed the fish already making its way over to the second exit. He stopped swimming and began treading water. Using all his strength he hurled the rock directly in front of the fish. His plan worked. The sea-beast spooked, thinking it was being attacked from the front, and swam directly into Yami's arms. He quickly pinned it to a rock behind him and straddled his own body on top of it to prevent its escape.
Yami observed his catch from bottom to top. My God! This thing is enormous! The tail alone must be- But he stopped midthought. His eyes had come to rest on something that didn't belong on a fish... Skin. Human skin. A hand wrapped around his wrist, which was still pinning the fish down by the tail. His head whipped up-
And his dark crimson eyes locked with hauntingly familiar purple ones. Yami was so startled he almost released the thing. Almost. But he wasn't about to let this catch of the day get away.
"It's not possible!" Yami screamed, "You're not real!" but he is... said a voice in his head, not only is he real, he's a-a-a-a "mermaid" Yami finished aloud.
[AN] totally predictable plot twist ftw! I know it's short and I considered adding a bit of random backstory/flashbacks for Yami but it didn't seem to really fit just yet.
