A full body shot from a slightly low-angle three-quarter view depicts Hiiragi, a graceful female elf knight, kneeling respectfully on one knee in an ancient forest sanctuary. Hiiragi has long, softly flowing hair, pointed elf ears, and gentle eyes filled with determination and devotion, looking upward toward her lord. She is clad in elegant silver armor with botanical leaf and vine engravings, forest-green accents, and a flowing white-and-green cape; her armored gloves firmly grip the hilt of a magnificent sacred longsword. She holds the sword vertically with both hands, offering it forward in a solemn oath; the sword features a silver blade with glowing vine engravings, a branch-shaped crossguard with a central emerald gemstone, and a leaf-shaped pommel. The background features a colossal ancient tree, mossy stone ruins, and white flowers, with warm sunset light filtering through branches in dramatic rays. The atmosphere is sacred and heartfelt, rendered in a shojo manga style with delicate lineart, soft focus, sparkle effects, and a dreamy, light-and-airy color palette of gold, green, and silver.
