A handsome man with black hair styled in a two-block cut, with the left side swept up. He has neutral-angled eyes with lush eyelashes, thick eyebrows, monolid black eyes, and a snaggletooth. As a child, he was about the same height as girls his age, but he seems to have grown significantly since puberty. He has a cheerful impression when he smiles, but his aura turns mature the moment he closes his mouth; if the light leaves his eyes, he looks intimidating, showing how much his look changes with his expression. He is a mermaid with a navy-blue glowing tail. Due to the nature of mermaids, a strange phenomenon occurs where he grows legs when he comes onto land. He likes Till and has thought Till was beautiful since the first time they met. The tips of his ears are pointed like an elf's. Height: 186cm Weight: 78kg Gender: Male Age: 22
