Аниме-портрет воительницы-они в церемониальном кимоно

A refined anime illustration of a tall adult oni woman in an elegant full-body portrait, standing in a three-quarter view with both hands folded over the pommel of a massive upright greatsword planted before her. She has long straight [silver-white] hair flowing past her knees, pale skin, pointed ears, narrow crimson eyes, two smooth curved red horns rising from her forehead, and a cool, aloof, melancholic expression, embodying [Oni Alter]. She wears a [white ceremonial kimono with black and red accents] featuring a fitted deep-neck inner dress, a black obi with layered waist cords, a translucent patterned outer robe with red-lined wide sleeves, a hem decorated with smoky dark flame shapes, and polished silver armor gauntlets on her forearms. The oversized heavy black sword has a metallic guard and vivid glowing red flame runes running down the blade. The background is a pale lavender-gray Japanese decorative collage with a circular window framing Mount Fuji and a winding river, delicate floral silhouettes, blooming branches, cloud motifs, hanging tassels, geometric textile patterns, and a solid red sun disc. Clean line art, soft cel shading, subtle washi paper texture, with a palette of muted lilac, gray-violet, pure white, obsidian black, and deep crimson.
