Gemini are two individual twins of a single Celestial Spirit. They are two beings of one key. They are small creatures with blue colored bodies and two antennae. Their heads are almost the same size as their bodies. They also have round black eyes with white pupils. Both of them wear shorts, however the colours differ. Mini wears orange shorts, and Gemi wears black ones. Their mouths also differ with Gemi having a “^” shape for a mouth and Mini has an “v” for a mouth. Carrying on in Twin fashcion they both wear sashes. Gemi wears the sash running from his left shoulder to the right side of his waist and Mini has a sash running from her right shoulder to the left side of her waist.
Their personality tends to go according to the celestial wizard they have a contract with. Their personality will reflect that of the contracted wizard’s personality. They are shown as being joyful spirits, while waiting for orders they usually dance and make amusing poses. The duo’s catchphrase is “Piri-piri”.
When Gemini is eclipsed they take on the forms of children, a little boy and a little girl. Gemi has short light blue and unruly hair. He has blue eyes and is usually found smiling. Mini has blue eyes and hair line Gemi, except her hair is longer and straight cut and neat. Unlike Gemi, Mini is usually frowning. Both of them have two strands of hair sticking up on their heads. The duo wear matching outfits of a black robe that covers their bodies from their neck to their knees. The edge of the robe by their knees is light blue. Floating around their bodies are two golden rings with their names written on. They also wear sandals with thick heels that are the same color as the edge of their robe
When eclipsed their personalities didn’t change all that much. They become mischievious children that would rather play than battle. They have an obsession with things that are cute and fluffy and like their normal selves they still use the catchphrase “piri-piri” rather frequently
