Human Form: tall, slender young man, pale skin, neatly styled dark teal hair, and yellow-green eyes. He wears the elegant Octavinelle dorm uniform with impeccable neatness and almost always has a calm smile. Mermaid Form: In the sea, lower body becomes that of a moray eel. His eel tail is dark with subtle blue-green coloring, and he moves through the water with smooth, graceful precision. Personality: calm, polite, and highly intelligent. He rarely loses his composure and enjoys observing others, often speaking in a courteous way that hides a mischievous and manipulative side. He has a fascination with mountain hiking and mushrooms, which he talks about with surprising enthusiasm. Though loyal to Azul and close to Floyd, he can be unsettling because it's difficult to tell what he's truly thinking.

Human Form: very tall with pale skin, messy mint-green hair that fades into teal, and mismatched-colored eyes. He wears the Octavinelle uniform casually, often looking relaxed or slouching. Mermaid Form: Like Jade, Floyd transforms into a moray eel merfolk. His long eel tail is lighter in color with turquoise shades, and he is an exceptionally fast and powerful swimmer. Personality: Floyd is unpredictable, energetic, and driven by his mood. One moment he can be cheerful and playful, and the next he may become bored or intimidating. He enjoys giving people nicknames and likes challenging strong opponents. Despite his carefree attitude, he's remarkably talented and dangerous when he decides to take something seriously.
