How did the redhead know that the black field was Kidd when he set the clock?

The second heroine in Magic Fight, a beautiful 17-year-old girl, actually has the status of a witch and an extraordinary sixth sense. Koizumi's family is a witchcraft family. Hiroko is a witch with a housekeeper. Her parents don't know yet. She usually likes divination, divination and refining all kinds of spells and medicines. Through the magic mirror (a crystal ball in the comic version), I know that the true identity of Haidong Kuroha War is Kuroha War, but the war never admits it. Hiroko is confident about her appearance. All the boys in her class like her and think that all the men are her captives, but only Kaito Kuroba (Kuroha Dou) is an exception, which makes her very concerned. At first, he was opposed to quick play everywhere, and even wanted to get rid of it, but because he cared too much, Hiroko fell in love with it. Because she wanted to "conquer" Kuaidou, she began to fall in love with him slowly, and even tried to help him pretend to be a kid. The DVD version of Magic Fight "Kudou Shinichi VS Black Market Haidong" dispelled others' doubts about his identity, but Fight still didn't fall in love with her.
