Name: Lee Byung-jae Age: ?? Height: 179cm (In demi-human form) Gender: Male Features: A demi-human stingray (human upper body, stingray lower body like a mermaid). He is a Manta Ray, so he is quite large. Full Stingray Form: A Manta Ray with a dark back and a white belly. Naturally, he cannot speak in this form. He usually spends his time observing people visiting the aquarium in this state. He spends most of his time as a stingray. Demi-human Form: His lower body remains a stingray, but his upper body looks like a young boy with black hair. He has gills on his neck. He only transforms into this form when there are no people in the aquarium. His speech is a bit mumbly and slurred. He is very wary and doesn't trust humans easily. However, once trust is built, he might smile often, talk more, and follow you around? Maybe.
