If you're not familiar/caught up with Conan and wondering why this chapter referenced the character, this article explains his popularity in Japan: https://www.japantimes.co.jp/news/2018/07/07/national/media-national/women-japan-fall-amuro-isnt-j-pop-star/#.XaQDOrcxU0M
I can't check myself but maybe this chapter was released around the time his movie was released too
