Outfit Rei in celestial-themed armor or robes with intricate starry patterns and cosmic details. The design should include glowing elements like stars, moons, and galaxies. Add ethereal wings or a radiant aura to highlight Rei's celestial essence. The background should be a dramatic, starry cosmos or night sky with galaxies, nebulae, and celestial light effects. Ensure the artwork exudes grandeur and cosmic power, making Rei a commanding and awe-inspiring presence.
