She gains pearl blue, rounded lace sleeves while her skirt turns a blue gradient, with white to pastel indigo ruffled fabric around the bottom covered with bubbles.
In her Mode Elegant Sango, her longer hair is worn with a gold tiara adorned by a sapphire heart and the fabric from the original piece. She keeps her earrings and gains a new necklace. Her white, floor-length dress has scalloped layered sleeves and frill accents, with a pale blue ribbon on the chest decorated with a pink shell and sapphire gem. On the navel is a big white bow with a gold sphere and bunched, pearl blue fabric wrapped around the skirt. The top layer of skirting has pale blue lining and a layered white and baby blue ribbon on each side, adorned by a sphere with the shell and gem design, and ruffled tails. The second skirt layer is white scalloped with a stripe of gold, followed by a pearl blue petticoat covered with spheres. Her sleeves are plain white. In Royal form the gown gains a very big, pale blue lace ribbon with trident, shell, and and coral designs.
In her Grand Princess mode, her longer hair is in a tighter curl towards the bottom, her accessory now an ornate gold crown with a sapphire heart. Her white choker has a bow on the front and a blue sphere in the middle. She wears a white and gold dress with a ruffled split along the seam to reveal white to gold scalloped layer lined in gold, and a white petticoat. Around the shoulder is a large gold cape with fluffy hood lining and white lined bottom, a baby blue bow cravat rests in the middle with a gold center. Her sleeves gain gold accents.
In her Mode Elegant Halloween, the fabric in her hair is worn with three big yellow flowers. Her chiffon dress has white ruffles to accent the layered sleeves, and a white collar. The pearls on the chest remain the same, but connect to a yellow flower with leaf on the navel, adorned by a blue pearl. Long, pearl blue ribbon strands hang from the flower. The skirt has a ruffled seam residing over two white layers. She gains layered white sleeves.
In the final, Minami's hair has been pulled back into a braided ponytail and she wears a white lab-coat.
