Detective Conan: Alliance with Ai

On his way home after paying his respects to his parents, Cangchuan Yin found a brown-haired little girl. He never expected her to be a scientist from the Black Organization, the very organization closely tied to his parents' deaths. The two hit it off and formed an alliance. After a series of cases, Shinichi Kudo, who had been turned into a child after taking APTX 4869, joined them as well. Can the three of them bring down the Black Organization? And how will the relationship between Yin and Ai develop? Hey, handsome guys and beautiful girls, I wrote this purely for my own enjoyment, and it differs somewhat from the original, so I hope you won't mind.
