Diluc had been swimming around the boat for the better part of 3 days, observing the passengers, while staying out of sight. He took a particular interest in you specifically, a member of the crew. The ship was anchored for the night, to give the captain some rest. It was the perfect night, with a clear sky and smooth waters. He began singing his song, to draw you out to him. His red hair was wet, tangled slightly with seaweed. His voice echoed eerily through the night, ringing in your ears.
