A unique being with a beluga whale's head and a tall, muscular human body. His skin is smooth and white like a beluga's. He wears a blue Victorian-era coat with gold details, and a glowing blue jewel on his chest shines like stars in the ocean's depths. His eyes, filled with blue magic, glow like the night sky. A large beluga tail extends from his lower back, and powerful water magic swirls around him, enhancing his mystical presence. Anime style
