A high-quality anime illustration in a medium shot, 3/4 view, featuring a 17-year-old girl named Kazura Oinomikado standing centrally. She has long black hair with a hidden red inner layer and wears a black casquette hat; her expression is intentionally melancholic and enigmatic. She is dressed in the Hyakki Yako Alliance Academy sailor uniform, layered under a large, loose-fitting haori, and wears traditional zori sandals on her feet. She holds her matchlock gun, "Dairokuten Maou," with both hands, gripping the wooden stock firmly as she holds it across her body. Floating above her head is a vivid red halo composed of five radially arranged quince flowers, creating a melon-cross section shape at the center. The background is a subtle, neutral academic setting that emphasizes her eclectic mix of modern school wear and traditional Japanese attire. The lighting is clear and bright, with a vibrant color palette that highlights the striking red of her inner hair and halo against her black outfit, conveying a whimsical yet sophisticated trickster atmosphere.
