Manga/Anime Differences

 * Added various events occurring on Monday, July 12th to lead up to the Enigma Boy, My Dad Is Not My Dad and Cheap Trick arcs.
 * Added a scene of Yoshihiro Kira worrying where his son is, but knows that he must have changed his appearance.
 * Added a scene of Jotaro Kujo talking to a Speedwagon Foundation member along with Joseph and Shizuka to discover if there were any missing people recently, including those considered runaways.
 * Added Josuke, Okuyasu, and Koichi talking to each other about how they haven't been able to find a single clue about Kira yet, but Josuke says Jotaro mentioned that he'll deal with it and they should continue being students.
 * Added Rohan looking at the photos he took and calling for someone to come by his house to give him an estimate so that he can renovate his house.
 * Added Yoshihiro spotting Kira (with Kosaku's appearance) on the street and recognizing that it's him because of his long fingernails and their bond as father and son.
 * Added Hayato filming Kira to find out who his dad really is, and Yoshihiro noticing that he was recording.
 * Rearranged events of the Enigma Boy, My Dad Is Not My Dad and Cheap Trick arcs to be in this episode, occurring at the same time as Let's Live on a Transmission Tower since they all took place on Thursday, July 15th. In the manga, the arcs were shown linearly with flashbacks instead.
 * Added Koichi running to school late and mentioning that he had class duties to get to.
 * Added Koichi being stopped by a mysterious boy on the way to school, and then only his schoolbag left on the ground in another scene later on.
 * Added Josuke yawning and being really tired because he stayed up late last night, while Okuyasu tells him he's in top shape because he got plenty of sleep.

Trivia

 * Rather than name the episode after its manga counterpart, the two-parter was renamed to the date "July 15th (Thursday)", to express and encompass the story arcs of Let's Live on a Transmission Tower, Enigma Boy, My Dad Is Not My Dad, and Cheap Trick which all occur on the same day.
