Milly Cotone is a youthful and strong-willed alien girl who lived in an ancient underground colony deep below the earth’s surface. All of her plant-comrades and family possess a small physique, they also fear the civilization above ground. However, intrigued by the stories of her taller ancestors who used to live above the surface, Milly emerged from the subterranean and ventured above ground to feel the warmth and potency of natural sunlight.
She is trying her best to photosynthesize and grow as tall and as powerful as the legendary giant Godzilla so that she could protect her people and the remaining greeneries from evil.
