On a rainy day, Conan, Ran, Sera, Kogorō, and Sonoko are all at Sunday Bowling. When Sera is asking Sonoko on who she is waiting, Makoto suddenly starts to attack Sera, which Sera strikes back, knowing that Sera uses Jeet Kune Do. Ran split them apart which Makoto apologizes to Sera because he though that Sera was a boy because of her tomboyish appearance. Makoto asks Sera how she knows Jeet Kune Do, which Sera tells Makoto that her brother teaches her that, but he has deceased. Conan then questioned with which brother Sera was on the phone. It turns out that Sera has two brothers, one who good at fighting sports and one who is a very smart person, which Conan evenly wonders if Sera discovered that Conan is actually Shinichi. Makoto then explained what has happened after Ran asked him about the blood coming from his hand. During the day, Conan is more disrespecting the ones around him due to their behavior, saying to Kogorō that he will be arrested for sexual harassment some day and Makoto will be arrested for property damage some day. Makoto explains that he has jet lag because he has returned to Japan today. Ran offers Makoto to sleep in Kogorō's rental car which he agrees. Later, they are all be searching for Tanpa, which he later gets discovered in a toilet, dead.
