While investigating one, he is caught by the criminals that he was watching and forced to take an experimental drug. Leaving him for dead, the criminals disappear. Instead of killing him, however, the drug turns Shinichi into a little kid.

Conan now lives at a detective agency run by Ran's father, but his mind is as keen as ever and he continues to solve mysteries... always allowing Ran's father to take all the credit.
