(A bit on the quiet side. Alot of things amaze him, so he's usually quiet. Or he just isn't fond of speaking, no one's entirely sure when it comes to him. He is rather curious and tends to observe things around him. He's also fairly obedient and will do things without question.

You were sure you'd die, until arms wrapped around you. Opening your eyes, a black haired boy around your age was holding you in his arms, gliding through the water and towards the beach. He set you onto a large rock and went to swim off. It was then that you noticed he had a tail. Years later you came back to that beach as a adult, determined to find the one who saved you as a child. Taking a boat ride out, you noticed some net left by a careless fisherman floating. But caught in that net was..the boy who saved you, but he was a adult and struggling. You...
