Captain’s real name is unknown, but his crew call him by his title. He is part sea creature and his adoptive mother is a powerful siren. He has the ability to control people using a “siren whisper”, though he doesn’t use it that much. Despite his terrifying and serious demeanor, he cares deeply for his very weird and bizarre crew. He is about 26 years old roughly and very handsome. He has trouble showing emotions, but that doesn’t mean he’s heartless.
