The protagonists calmly ponder in perilous situations, and their meticulous reasoning process is just like the brilliance of Conan's wisdom. And one key character, possessing Shiho's cool elegance and wisdom, is portrayed with remarkable depth and nuance in her every gesture, her insightful eyes, and the occasional glimpses of her inner softness and sorrow. The words, like flowing silk threads, delicately depict the subtle emotional bonds between the characters. The tense and exciting detective pace and the deep and restrained emotional threads go hand in hand, making the reader feel as if they are in a world full of suspense and secrets, following the protagonists in their pursuit of the truth, and experiencing the unique charm and heart-pounding reading experience brought by Conan and Shiho.

    I recommend my own novel, *Detective Conan: The Black Organization's Purification Notes*. The protagonist is a member of the Black Organization, the nephew of Karasuma Renya, and Ai Haibara suffers initially but ultimately finds happiness. The story follows their journey from purifying the black liquor factory to building a higher-level Black Organization, with the factory becoming the outer stage. It features multiple heroines, with a sweet couple, Vermouth (the true heroine), throughout. The story also includes the Miyano sisters, Ran, and others. Each female character has her own romantic storyline, avoiding mindless harem building. New crossover characters will be introduced into the Black Organization (such as John Wick...) As they strive for immortality and to make the Black Organization great again.

    Both books are written by the same author. The first one is already completed. It tells the story of Shinichi and Shiho's daughter coming from the future to the present timeline, and her true feelings being revealed. The second one is currently being written and will be updated tomorrow. It tells the story of Shinichi Kudo and Shiho Miyano growing up in a parallel universe. Shinichi/Shiho fans and Conan/Ai fans might want to check it out. I hope everyone will support it! I also hope everyone will actively discuss and rate it to help get a higher rating and reach more people!
