This illustration features a large ensemble cast of characters rendered in a classic anime style. In the immediate foreground, a young boy with dark, spiky hair and oversized glasses—the central protagonist—points forward with an expressive, determined look. He is dressed in a blue blazer, a white collared shirt, and a red bow tie. To his left stands a taller man in a white tuxedo and top hat, holding a monocle, providing a sharp contrast to the school-aged children and adults gathered around.
The composition is a dense, layered montage of various characters from the series, including students in school uniforms, professional detectives, and mysterious figures. The background is segmented by geometric shapes and blocks of muted colour, creating a framed effect for each group of individuals. The characters are captured with diverse expressions ranging from serious and contemplative to cheerful and energetic, characteristic of a high-stakes mystery narrative.
The artwork utilizes a clean, flat-colour palette with bold outlines typical of traditional cel-shaded animation. The lighting is bright and even, ensuring that no single character is lost in shadow, while the colour scheme features a mix of earth tones, deep blues, and vibrant pops of colour like the protagonist's red bowtie and the white of the tuxedo. The overall mood is professional and inquisitive, evoking the tension and camaraderie found in a suspenseful detective story.
