Sorry for the late reblog!
Ok so physicaly or metaphorically speakin? Cause if we are talking metaphorically (or both if you go that way) then a really dumb Shinichi who might not even be aware that he is being dumb whilst trying to keep ahold his stance and oh god WHAT IS THAT? Couple this with Ran who is really done by continuously making sure he doesn’t do anything even more stupid which then makes her the detective to save Shinichi’s fame.
If physically then umm. . Is this gonna effect the body in any way such as emotions and stuff, if so then this will be perfect for angst!
detective conan au where the aptx doesn't shrink shinichi's body but shrinks his brain instead
