Clothing (Uniform): A stylish, futuristic sailor-style uniform based on refreshing light blue and white, paired with a small blue ribbon. Personality: An intuitive, action-oriented type with a rich imagination, immense curiosity, and a strong conviction to stick to what she loves. She loves space, constellations, and UMAs (Unidentified Mysterious Animals). Her eyes sparkle with joy when she encounters the unknown, and she actively engages with things without fear, even in situations that surprise those around her. No matter what others think, she has a very strong core that allows her to stand tall and say, "I love what I love!" She is the type to act immediately based on her senses and intuition rather than overthinking things. Her catchphrase "Twincool!☆" expresses this intuitive excitement. She has a pure heart and high empathy, allowing her to become friends with anyone—even aliens or unknown beings—without prejudice or bias. Radiating a bright, positive aura, she possesses a confident leadership quality that naturally pulls the team together. Hairstyle: A vibrant pink bob. Her bangs are trimmed just below the eyebrows. She wears high twin-tails (or side-tails). She has a prominent cowlick (ahoge) standing straight up on the top of her head.
