After the Conan kidnapping case ended, Xu Yue had clearly stepped up his supervision of Conan. He simply ordered Maya to keep a closer eye on him and notify him if she saw a dark-skinned high school student with an Osaka accent come looking for the Mori Detective Agency.
There were Reincarnators in this world, and they were also searching for clues about Shinichi. All things considered, he had already minimized Kudo Shinichi's influence as much as possible. In several cases where Conan had solved them in Kudo Shinichi's name in the original story, he had used his own name instead.
Thus, to the Reincarnators, it would appear that Kudo Shinichi had vanished almost as soon as they arrived in this world.
Even so, he still had to interfere in the incidents where Conan turned back into himself. Mm, he just needed to snuff out every hope of him growing bigger in the cradle. How nice was it for him to obediently remain Conan? It would not be fun if he grew up...
Maya did not disappoint Xu Yue either. After Conan solved another two or three cases, she reported that a young dark-skinned man seemingly from Osaka had come to the Mori Detective Agency.
Upon receiving the notice, Xu Yue naturally headed straight for the destination.
With the favorability he had built up, there was no need to make an appointment before dropping by. They would welcome him warmly anyway.
When Xu Yue arrived at the Mori Detective Agency, he heard part of a deduction from inside before he even knocked.
"...The fact that he called you means he cares about you, yet he never asked how you were doing. Instead, he kept talking about himself, telling you not to worry. Clearly, he knew your situation very well.
