2.OVA "Crystal Children and Mothers"

3, comics: "Magic Fight"

4, 76-77 episode "Kudou Shinichi VS Blackmarket Haidong" 2-hour special.

Besides the magic fight, I think episode 2 19 can best show the love between Qing Zi and the magic fight.

Fighting, Qing Zi is very similar to Xiaolan and Xinyi. Xinyi and Kuaidou have the same seiyuu, and Xiaolan and Qing Zi have the same seiyuu. Moreover, the two couples are childhood friends, and sometimes they quarrel. Men also have a secret from women: it is strange to keep it from Qing Zi himself; Xinyi hides Xiaolan from herself and becomes Conan.
