Enlisted by a man by the name of Yasuhiro, Makoto helps investigates the death of a man named Toshi who was involved in a gang called Team Apollo.

Plot
One night, Makoto is approached by an old man named Yasuhiro Nanjo. He asks him if he passes by the location often as there was a manslaughter victim there. The two talk by a staircase not how they'd be the same age as someone close to them. Yasuhiro details that his son Toshi who was the leader of a street gang died five years prior. Asking for help, Yasuhiro enlists Makoto to find information on street gangs and Makoto agrees to it. Just then Harumi Matsuda and son Akihiro Matsuda arrive and Yasuhiro introduces Makoto to Akihiro. At that moment, a man in a red hat who is acquainted with Harumi approaches her. Harumi tries to brush him off until she spots a woman that she knows leaving her notably perturbed. Because of this, Harumi leaves with Akihiro, and Yasuhiro drives Makoto home in his "Jazz Taxi".

The following day, Takashi contacts Makoto informing him that none of the G-Boys members current and former know nothing about any murders from five years ago. However, news of a gang from Ueno known as Team Apollo was brought up that Toshi was apart of. Makoto visits a bar frequented by Team Apollo and asks the bartender there for information on Toshi. One of the patrons acts apprehensively and without starting a conflict, Makoto leaves the bar, but goes around town interviewing various people. Eventually, Makoto is confronted by the men from the bar and they take him out. Before leaving him they warn him to never show his face again in Ueno.

Yasuhiro visits Makoto at his mother's store and he informs the old man about how he was beaten in Ueno and that he plans on confronting the Apollo Gang again. Afterward, Makoto goes back to the bar meeting with the thug who confronted him in both the bar and alleyway. Using Yasuhiro as leverage, the thug allows Makoto to meet with Team Apollo's current leader Rintaro Nagai. From him, Makoto learns more about Toshi and that if he wants to learn more ask Harumi. Driven home by Yasuhiro, Makoto tags along with him as they pick up Akihiro from kindergarten. During this time, Makoto presses Harumi about Toshi and she confirms all of what Rintaro told him and more. After a confrontation between Harumi and Toshi, she later found him dead.

Driven home by Yasuhiro's taxi, Harumi is approached by the woman that she saw the night she first met Makoto, her name is Misako Matsuoka. When pressed for more information about Toshi's death, Harumi recalls nothing else of use. Later, Makoto contacts Reiichirō for help and he reveals testimony involving the Toshi's murder investigation. Learning this, Makoto contacts Harumi and tells her he's going to meet with Yasuhiro a week from then and tell him a fabricated lie.

A week later, Makoto meets with Yasuhiro at Toshi's murder spot. There Misoka and her husband appear and introduce themselves. Harumi appears as well and Misako confesses that she killed Toshi. Chiming in, Harumi reveals everything to Yasuhiro, and Misako along with her husband promise to turn themselves in after their baby is born. However, Yasuhiro forgives them as it'd be improper for their soon to be born child and blames himself for his incompetence. Being driven home by Yasuhiro, Makoto details to him that if he was his son, he'd be proud of him.
