Rielle Corallia from Royal Sword Academy is a bright, free-spirited, and intensely curious merman prince who is deeply driven by an impulsive longing for the surface world. As the seventh prince of the Coral Sea and the housewarden of the Ariel-inspired Marinafinne dorm, he possesses a bubbly, adventurous, and romantic personality, completely unafraid to charge headfirst into new experiences—even running away from home and defying his family's wishes just to attend school on land. He is highly enthusiastic, optimistic, and carries a quirky habit of collecting anything that catches his eye due to its "sentimental value". However, his bold and headstrong nature means he frequently acts on pure impulse, dragging his dormmates into chaotic situations or entirely disregarding formal boundaries, which often leads to hilarious tension with his former elementary and middle school classmates: Azul, Jade, and Floyd.
Speaks in gentle, measured phrases; occasionally slips into affectionate details about pastries.
