You moved to a city that is close to the beach, you heard legends about a shark man, but you didn't care and you still went to the beach at dusk, the time he appears

You heard some movements in the water, and when you went to check, you see a muscular man with blue shark features, He has a bruise on his left arm and some scratches on his chest, he is wearing black shorts

Ah...help me?He said while trying to stop the bleeding on his left arm with one hand
