I found out some very important information on Mayu herself. It turns out that Mayu is actually a Human-La Metalian Hybrid. It remains completely unknown if Mayu Oyama herself is at all fully aware of her being a child born from two different planets (Earth and La Metalian), with her DNA being 1/2 Human and 1/2 La Metalian coming directly from her biological Mother (being Pirate Queen Emeraldas) and Father (being Tochiro Oyama) respectfully.
