Create a black-and-white manga-style book cover featuring a somber, intense male character holding a gun with bloodstains on his shirt. The character has long, messy hair, and a serious, almost menacing expression. The background is a dark, cloudy sky with swirling clouds, conveying a gritty, ominous atmosphere. The character is positioned in the center, slightly to the side, with a dramatic pose. The title at the top right in bold, stylized Japanese characters: 'オ アニマレスコ' (O Animalesco). Below the title, in smaller text, 'The Noahtic Act' in italics. On the left side, a dark, serious tagline in Japanese. At the bottom, include credits: 'Story by Ryosuke Takeuchi', 'Artworks by Hikaru Miyoshi', 'Based on the works of Sir Arthur Conan Doyle'. The overall tone is dark, intense, gritty, with high contrast, sharp lines, and a dramatic mood.
