After the event of 1 year ago Shinichi is now back to normal self. But after leaving friends behind he still uses his bow tie voice changer he is able to talk to Genta Mitsuhiko and Ayumi. But sometimes he just doesn't hasve the time since they are now freshman in Shinichi original highschool. And Shinichi is just his years of college with Ran and Sonoko. Maybe a poison of APTX 4869 will come back to haunt him.
