High-quality anime-style illustration of a young-looking androgynous boy with a delicate, doll-like appearance. He is actually a demon who can freely change his form and age. Has small hidden horns, subtle devil wings on his back, and a thin devil tail that can appear or vanish at will. His eyes are jet black with glowing purple pupils, droopy and mysterious. He wears light purple eyeliner, giving a decadent and sweet aura combined with a faint sense of authority. Short light-blonde hair with straight bangs and a soft bob cut. His skin is pale with a faint sexy pink tint on his cheeks and joints. He is wearing a playful Halloween-themed cosplay costume: asymmetrical bikini-style top — right side shaped like a jack-o'-lantern, left like a ghost with frilled edge, matching bottom with spiderweb mesh at the waist, bat ribbons on both hips, and a black spider pattern at the center of the design. Witch hat with a wide brim, decorated with hanging Halloween charms (pumpkins, ghosts, bats, spiders), and cute seasonal accessories such as pumpkin earrings and bat-shaped hairpins. Soft magical lighting, cinematic glow, focus on costume silhouette and playful seasonal atmosphere.
