Is Haiyuan Ai an adult? Is it the same fate as Conan?

Yes, about Conan's age. She used to be a member of the organization, code-named Shirley. She stopped work to protest because she couldn't see her sister. Organized people are locked up. She was desperate, so she ate AptX4869 with the determination to die. I didn't expect that, like Conan, there was only a small chance of getting smaller, but it really got smaller. I escaped from the garbage dump and decided to go to Conan, so I fainted in front of my new home, was saved by Agasa Hiroshi, and then entered Didan Primary School, and finally even Conan was scared, but that's another story. When Conan sent him home, Haiyuan Ai pointed out their identities to him.
