The Girl in the Back

 * Three years ago, a 15-year-old boy is on the run from two police officers.
 * A man, respected by the police, decides to take care of the situation by himself.
 * The man takes the boy, Protagonist, to a coffeehouse; the boy ran away from his orphanage to find his parents' whereabouts.undefinedThe man, a private detective named Shunsuke Utsugi, convinces him to become his assistant.
 * A few months later, Utsugi and Protagonist receive a phone call to check over a crime scene.
 * The victim is a freshman schoolgirl named Yoko Kojima. Her time of death is estimated to be around 9-10 PM on October 10.
 * Protagonist gathers information from Ushimitsu High School to solve the Yoko case, and connects it with the Genjiro Kaneda case.
 * Yoko was deep into an investigation of "The Tale of the Girl in Back"; this rumor involves a ghost of a blood-soaked girl that stands behind a student.[19]
 * The "Girl in Back" story originated 15 years ago, when a schoolgirl of Ushimitsu, Shinobu Asakawa went missing. This was around the same time of the murder of Genjiro Kaneda; that case's statute of limitations was going to expire soon.
 * Protagonist learns more background about the ghost story.
 * Ms. Hayama, a teacher at the school, admits to Protagonist that she started the rumor.
 * On the night of the Kaneda murder, the then sophomore went to the school to get some forgotten homework, but saw the "Girl in Back".
 * Hayama confirms passing by the old school building during the night she saw the "Girl in Back", but the wall was unfinished.
 * During the conversation, Protagonist catches Tazaki eavesdropping. He tries to chase him down, but fails.undefinedAfter he returns to the detective agency, Ayumi gives him a cup of coffee that makes him go unconscious.
 * He gains his consciousness, Protagonist realizes Ayumi drugged his coffee; a letter from Ayumi says she went to track down Tazaki herself.
 * Protagonist searches through a town, and ends up in a downtown galleria. Eventually, he ends up from Tazaki's apartment, to his mother's village, and finally down a cliff, where Ayumi is kept hostage by an unstable Tazaki. He threatens to kill her, but gives up afterward. He confesses about his false alibi and talks of his past.
 * Protagonist has the altruistic Urabe admit he lied about Tazaki's alibi, but he showed no regrets.
 * Protagonist finds that many students and teachers - particularly Mr. Hibino - respect Urabe as a fine educator.
 * Protagonist notices a portrait of Shinobu in the school; the painter, Ryoko Katsuragi, tells Protagonist about Shinobu's personality. Yoko and Shinobu were also cousins.
 * When Protagonist arrives at Goro's apartment, the game presents a scene of Goro getting murdered.
 * Protagonist realizes that Goro was the man Urabe hanged out with at the galleria. He was holding a pen with the initials "T.U."; these match the initials of Teruhiko Uchida and Tadashi Urabe.[34]
 * Sayaka Ishibashi tells Protagonist that the Uchida boy was indeed Teruhiko's son, Tatsuya.
 * This boy later turns out to be Tatsuya Hibino.
 * Hibino tells Protagonist about how he developed his father-son relationship with Urabe. He also shows his extreme resentment towards the Kanedas. He has no alibi for the Goro murder, but throws a temper tantrum when Protagonist considers Urabe a suspect.
 * Conversing with Hayama, Protagonist realizes Urabe was never on any business trip, as he claimed before. When she went to school on the night of the Kaneda murder, through the window of the old school building did she see the bloody girl - this was likely Shinobu.
 * Tazaki reveals that on that night he was indeed plastering the wall of the old school building, but he took a break. The next morning, it looked like someone had used his tools.
 * Back at the detective agency, a resentful tipster calls to tell that the "lowlife" was at the school.
 * Ayumi was taking a make-up test for Hibino before they went outside to meet Protagonist.
 * The three break through the door into Urabe's office, and Protagonist is shown a visual of the suicided Urabe.
 * Urabe had left a suicide letter; on it, he shamefully confesses as the serial killer.
 * Hibino is revealed to be the serial killer.
 * Flashback: Hibino makes detailed confessions of his murders.
 * After confessing about Genjiro, Shinobu, Goro, and Yoko, Hibino tries to slash the cornered Protagonist and Ayumi in the hallway with the giant mirror. Instead, he ends up stabbing the mirror and shattering it into pieces. It reveals the corpse of Shinobu; as police, Maruyama, and Utsugi arrive, Ayumi faints.
 * Utsugi and Protagonist discuss their findings.
 * Afterwards, Utsugi introduces Ayumi as an official assistant of his.
 * When Protagonist asks Utsugi about the "T.U." pen, he does not answer why it didn't read "T.H." instead - but he and Ayumi go out to eat, leaving Protagonist behind.
 * Hibino was Urabe's son all along - having lost his wife after she gave birth to Hibino, Urabe entrusted his son to his friends, Mr. and Mrs. Uchida. The "T.U." initials on the pen are then revealed to be directed not to Tatsuya Hibino, but to Tatsuya Urabe, his son.
 * Two years later, Zenzou Tanabe calls the Utsugi Detective Agency over to his Myojin Village.
 * Protagonist goes out to the village, while leaving behind Ayumi.
