Anime girl with spear overlooking fireworks at temple

A girl with long crimson hair and a single short ponytail on the right side tied with a large black bow with red string, golden eyes, an ankle-length white dress with red circular rivets with black lines, a short black skirt with loose and dangling black belts, gold-trimmed skirts with red crystals at the edges of the material, long black socks with white tips, athletic shoes, a girl holding a red and white spear with hanging crystals in shades of black and gray, a girl standing and watching the fireworks display from the temple mount towards the small city and the sea on a starry night.
