Summary
Koichi is now looking for the murderer of Reimi, who died 15 years ago, but the lack of evidence stopped any serious investigation. Upon telling Reimi's story to Josuke and Okuyasu, Josuke remarks that even if that story is intriguing, if the killer isn't a Stand user, then there's nothing he, Jotaro or the Speedwagon Foundation can do as they are not chasing common criminals. He suggests investigating the whole affair patiently, saying that the killer won't magically stumble upon them when Koichi is almost run over by a man. The driver discusses with his unseen girlfriend, and when he arrives at his house, the man named Kira takes the girlfriend, revealed to be a bleeding severed hand, into his home.

Meanwhile Rohan is at the local cemetery, confirming that Reimi did die 15 years ago, when he meets a monk who recognizes him too as the "little Rohan". Seeing Reimi's tombstone, the monk mentions how terrible the incident was for Rohan's family. Puzzled, Rohan asks what is his connection to her, and the monk hesitantly reveals that at the night of Reimi's murder, she was babysitting a 4 years old Rohan, and Reimi threw him out of the window to save him from the murderer. Now knowing why Reimi was acting as if she was close to Rohan, the investigation becomes personal for the mangaka.
