Jujutsu Kaisen character anime poster city elegance

Create a vertical Japanese anime promotional poster, featuring from "Jujutsu Kaisen", using a unified hierarchical key visual composition and dramatic ink collage style. Canvas: 3:4 vertical poster, using a warm-toned off-white old paper texture with subtle grain, dust spots, minor scratches, and scattered ink marks. Visual hierarchy: The upper half is dominated by a huge close-up of Gojo Satoru's right profile, wearing a black blindfold, with a slight smile at the corner of his mouth, his spiky white hair exploding upward, turning into translucent feather-like fragments and blue-purple energy streams. In the center foreground, place a full-body Gojo Satoru walking toward the viewer, tall and slender, wearing a high-collared black uniform, blindfolded, one hand in his pocket, the other hand raised with two fingers extended; red cursed energy lightning coils around his torso and legs. Use deep indigo, violet, blue, black, white, and deep red as accents, combined with expressive ink splashes and sharp manga lines.
