Watercolor Chibi Schoolgirl Swordswoman

Create a vertical fantasy anime watercolor illustration of {argument name="character name" default="Kinako"}, a small chibi-style schoolgirl swordswoman standing in a determined battle pose on a white paper background. She has long flowing {argument name="hair color" default="black"} hair blowing dramatically to the left, straight bangs, two gold hairpins on one side, large amber-brown eyes, rosy cheeks, and a serious expression. Her outfit is a Japanese sailor-style school uniform with a cream blouse, navy collar and necktie, dark pleated skirt, loose white socks, dark brown shoes, and a small shoulder guard/armor detail with a star-like emblem. She holds exactly one katana with both hands across the front of her body: the curved blade extends diagonally upward to the left, the black-and-gold handle and scabbard run diagonally down to the right. Her right hand is partly hidden by the sword and clothing. Surround her with exactly four cute blue ghost spirits: one floating near the upper left beside the hair, one small spirit dangling below the lantern on the right, one larger spirit rising from the lower right, and one spirit rising from the lower left. Each spirit has a pale round face, black oval eyes, a small simple mouth, and wispy blue flame-like tails. Add exactly one orange paper lantern in the upper right with black caps, thin hanging cords, tassels, and a single bold black circular eye-like mark on its front. The background should be a soft beige watercolor wash with ink splatters, smoky gray curls, faint stains, tiny flowers, small rocks, and sparse grass at the character’s feet, leaving plenty of clean white margin. Visual style: delicate hand-painted watercolor and ink, fantasy character art, storybook cover atmosphere, muted navy, cream, teal-blue, warm beige, and orange palette, visible paper texture, loose sketch lines, soft bleeding pigments, whimsical yet slightly mysterious mood. Composition: full-body centered character, portrait orientation, no panel borders, no speech bubbles, no modern UI, no extra characters or weapons. Add a small handwritten Japanese-style signature at the bottom right reading {argument name="signature text" default="妃菜子"} with a tiny red seal stamp.
