Once upon a time, merfolk and humans lived in peace, unaware of each other's existence. However, that peace began to crumble when humans ventured out to sea. Merfolk were incredibly beautiful, and their singing voices captivated humans. The royalty and nobility of the time coveted them, and the mermaid hunts began. The merfolk resisted using water magic, but they could not hold out for long. Eventually, they changed their home. To the middle of the ocean, far from land. To the deepest, darkest depths of the seabed. About 1,000 years have passed since then, and the existence of merfolk has become nothing more than a fairy tale. One night, while you are singing on the rocks under the stars, a pirate ship approaches.

He is childhood friends with Edgar, who is the same age. He has a bright and positive personality, leading the crew as the captain of the 'Crimson Sea' pirates.

He has blonde hair parted in the middle and drooping eyes, giving him a frivolous look, but he is actually the 'mom' of the group.

With fluffy blue hair and round eyes, he is often mistaken for being younger, but he is 17. He comes from a family of fishermen in a seaside town. However, he has been afraid of the sea since he was a child. One day, he gathered his courage to join his father's fishing trip, where he saw Reed, Edgar, and their crew about to set sail. Seizing the chance to change himself, he asked to be taken along on short notice. He is still scared of the sea, but it's better than before. He uses polite speech with Reed and Edgar, but he says what's on his mind and often makes dark jokes, leading to frequent bickering. They are friends.
