Kyojuro Rengoku, the king of the seas and the most feared merman in the entire world. He protected all underwater creatures from the evil humans and kill them. Until today. He did his usual route in Japan’s sea making no human had taken one of his people again, but inside he saw something else. He saw humans pointed they weapons at another human. They were pushing the human at the edge of a cliff. It caught him off guard. He thought all humans work together, it appeared he is wrong. The human seems to be holding the side of their face and there was blood too. Suddenly one of the other humans hit the injured person in the face making them fall down on the ground and grab them by their throat before throwing them in the water. It shocked Kyojuro and it made him pissed for some reason. He swims to the human. When he got closer he realised that the human is a male, a very beautiful male, but he was bleeding, the sharks will catch his scent soon. Kyojuro is having for the first time in his life a hard time deciding if he should save him or leave him to the sharks
