Early October

• Hitomi Sagan went to Fuchu Prison to meet with Inmate #89 for one of her regular meet-ups. Afterwards, Hitomi spotted "Shoko Nadami" (who was actually Saito Sejima) arriving to meet #89 himself. Saito met #89, and during their conversation, #89 realized that the person inside Shoko was Saito himself.
• Renju Okiura was in his office at Lemniscate crying, presumably about Manaka Iwai's death almost 18 years ago, when Mizuki Okiura spotted him through the door. Suddenly, Renju stepped outside and drove towards the Cold Storage Warehouse, and Mizuki followed him in a taxi (potentially Takushi Ibarado's taxi operating near Lemniscate).
  • Renju arrived and lamented over Manaka's corpse, while Mizuki hiding behind the shelves. Once Renju left, Mizuki approached the frozen forklift and found Manaka's body inside. Thinking the body was Iris Sagan, she hurried over to the Sagan Residence and encountered a still-breathing Iris. Mizuki proceeded to convince herself that what she saw was simply an illusion, repressing the memory.

Around October 25th

• Inmate #89 made a phone call to So Sejima, first answered by his secretary. When So took the phone, #89 told him "A woman named Shoko Nadami knows what happened 18 years ago. Contact her. I realized everything when Shoko arrived. I have to see her again," alluding to Rohan's knowledge of Saito Sejima.

November 1

• Around 4 PM - Renju Okiura received a call from Saito Sejima (a parasite inside Shoko Nadami), asking to meet him at a factory in the Kabasaki District.
• Around 5 PM - Renju arrived at the Kabasaki Chemical Plant, where he was sedated/knocked unconscious by Saito (in Shoko). Placed in the Prototype Psync Machine, the two swapped bodies. Saito (in Renju) proceeded to stab Renju (in Shoko) to death with an ice pick, and then ate Shoko's eye.
• Between 6:00 PM-8:00 PM - Saito (in Renju) took Shoko's body and drove through the abandoned subway line. He arrived at Bloom Park, strapped her body at the merry-go-round, and stabbed the ice pick in her eye socket. Her phone dropped, and Renju placed it inside the adjacent horse ride's mouth.
  • 8:05 PM - Saito (in Renju) sent a NILE message to Mizuki Okiura, and then lied in wait for her. The message read: "Mizuki, Daddy got caught in something serious. Please come to Bloom Park's merry-go-round right away. Daddy needs your help. Please, do as I say."
  • 8:10 PM - Mizuki called Ota Matsushita and asked him to come with her to visit Bloom Park, so that she wouldn't go into the restricted zone alone. Ota agreed, and they set out to meet nearby.
• 9:00 PM - Mizuki and Ota arrived at Bloom Park, and together they found the dead corpse of Shoko Nadami. Ota fled from the scene in fear and dropped his phone in a puddle, while Mizuki stood staring at the body in shock. She saw the silhouette of Renju in the distance by the park's back exit.
  • 9:02 PM - So Sejima, curious about last week's phone call, decided to use a rental phone to call Shoko Nadami. Her phone rang inside the horse ride, and with that —along with the sight of the mysterious silhouette—, Mizuki hid inside the merry-go-round pillar out of fear. Saito (in Renju) approached the pillar, locked the inside, and drove away.
  • 9:05 PM - After fleeing from the park and realizing he dropped his phone in a puddle of water, Ota went to a nearby pay phone and called the police. Leaving an anonymous tip, he told them that screams were heard from inside Bloom Park, and returned home for the night.
• Between 9:30-11:00 PM - With Mizuki hidden inside the locked pillar, the First Response team arrived at Bloom Park and reported the scene. The forensic crew, lead by Araya Kagami, arrived with the police, and Detective Akasaka investigated the crime scene as lead detective.
  • Around 10:30 PM - The corpse found is identified, and the information is sent to Shizue "Boss" Kuranushi. Recognizing the name "Shoko Nadami," Boss contacted Special Agent Kaname Date, to go and investigate the scene himself.
• 10:54 PM - Kaname Date and Aiba arrived at the scene, and began investigating the corpse. He spoke with Boss (and befriended Kagami), and soon the four heard a noise coming from the pillar. Blasting the lock open with Evolver, Date found Mizuki inside.
• Around 11 PM-12 AM - Date took Mizuki to Central Hospital, where she was admitted into a room for the night. Date called Renju, in order to tell him about Mizuki, but Saito didn't picked up the phone. Date stayed with Mizuki the whole night, and soon enough fell asleep.
  • Aiba entered Date's dreams, as Date began to remember parts of his past, particularly the event in which he accidentally show Hitomi Sagan in 2013.

November 2

• In the Morning:
  • The Metropolitan Police Department broke the news on the death of Shoko Nadami, keeping information down to a minimum. Her name is spread wide, and many people heard the news of her death, including Iris Sagan, Moma Kumakura, So Sejima, and even Inmate #89 all the way in Fuchu Prison.
  • Saito (in Renju) is taken into interrogation by the MPD investigation team (most likely lead by Akasaka) in regards to "his ex-wife's" murder.
  • Iris headed to the Lemniscate Entertainment Offices, where she met up with Ota Matsushita. While talking, Iris brought up Shoko's murder as a topic, and Ota confessed to what he and Mizuki saw that night. Soon after, Iris headed to the recording booth for her podcast.
  • At Central Hospital, the doctors determined that Mizuki was suffering from aphonia due to the traumatic event.
• 9:21 AM - Kaname Date arrived at Boss's office, and the two discussed the developments in the recent case. During the conversation, Aiba popped out and revealed she identified the anonymous caller as Ota Matsushita. With that, Date and Aiba depart to investigate.
• 10:18 AM - Date arrived at Matsushita Diner, where he met Mayumi Matsushita. She recounted memories about her husband and the gift her son made her. After finding a Azamon box with an A-set figurine, they learn that Ota could be at Lemniscate.
• Around Noon:
  • 11:45 AM - Date arrived at Lemniscate, where he found Ota in the middle of sockpuppeting for A-set online using his 3 extra accounts. Date struggled to get his attention until Aiba hacked his laptop, at which point Date used it to blackmail Ota and he confessed to finding the body with Mizuki and keeping quiet about it.
  • Once Iris's podcast ended, she left the recording booth, met up with Ota, and is introduced to Date, who vaguely recognized her. After several questions, Date decided to leave, but Iris put up a scandalous show on him —with Ota recording— and used it as blackmail to take her along. With that, Date takes Iris to Bloom Park.
  • Noon - Saito (in Renju) is released from interrogation, and soon resumed his master plan for his next target: Iris.
• In the Afternoon:
  • Inmate #89 sent a phone call to the MPD, where Detective Akasaka picked it up. #89 stated that he knows who killed Shoko Nadami, and offered a plea bargain.
  • Saito (in Renju) made a private reservation for a nighttime event at Sunfish Pocket, then prepared for his next kill by purchasing beer kegs and hooks.
  • Boss blackmailed the director of Central Hospital in regards to his sexual harassment of the Hospital's nurses. The director allowed Boss to take Mizuki to ABIS to prepare her for a Psync.
• Around 1:00 PM - While driving to Bloom Park, Iris and Date got acquainted with each other. The two talked about their respective jobs, and Iris mentioned that she is "going to die soon." Her real name caused some of Date's memories of him with a young Iris to resurface.
• 1:12 PM - Date and Iris investigated the park. Iris gave off useless mythology trivia and Illuminati conspiracy theories, but then asked about the ice pick in Shoko's eye. Date noted that the ice pick was found in Mizuki's hands, and that the crime scene has no blood around the body. Date determined that Mizuki had pulled out the ice pick from Shoko's body, and that the crime actually occurred elsewhere. With that, Date decided to leave, but suddenly, Iris's brain tumor caused her to collapse. Date carried her to the car, learning she weighs 105 pounds.
• Between 1:00 PM-3:00 PM - While driving to the Sagan Residence, Iris rolled down the window and took in the cool breeze and playing with the air. She remarked about how Date appeared to be familiar to her in some way.
• 3:09 PM - Date dropped off Iris at her house, but before leaving, he spots Iris's mother through the door, and recognized her as the woman who was in his dream the previous night. Iris welcomed Date inside as she served him some tea, and they have a small conversation. Hitomi talked about her relationship with Renju and Shoko, and about Iris. She also mentioned her shoulder injury, while Iris talked about the winter iris flower at home. After some talk, Date decided to leave, and promised to see Iris again.
• Around 4:00 PM - On the way back to ABIS, Date and Aiba discussed the timeline of events for this particular case. They went over "Shoko's" time of death and all the new clues gathered today. Together, they concluded that Mizuki couldn't have murdered her mother after all.
• From 4:26 PM-4:46 PM:
  • Date arrived at Boss's office to find Mizuki waiting there. Boss convinced him to Psync with her, in order to get clues as well as to potentially cure her aphonia.
  • As Pewter prepared the Psync, Date discussed the specifics of the Psync and the case with both him at Boss. Date explains to the mute Mizuki his work at ABIS and the process of Psyncing, and then promised her some food.
• 4:46 PM - Date and Aiba entered Mizuki's dream of Bloom Park.
  • They removed an "ice pick" from a photograph of Shoko and attempted to remove a giant cage encasing the merry-go-round. They eventually found two large Bird Cages, one with a torn up picture and another with balloons.
  • Date chose to lift the left Bird Cage, and rebuilt an old picture of the Okiura family visiting Bloom Park 8 years ago. After remembering the event surround the torn picture, the pair free Mizuki from the pillar, and Aiba embraced her to soothe Mizuki. In doing so, a Blue Figure appeared leaving the park's back exit.
• 4:52 PM - After the Psync, Mizuki was healed from her aphonia, embracing Date. She provided further testimony about the figure she saw and the actions she took at the park. Boss assigned Date to return to Bloom Park for further information, and he decided to bring Mizuki along to specify where the figure was standing.
• 4:58 PM - Saito (in Renju) called Iris and asked her to meet with him about a gig at Sunfish Pocket. Iris agreed, and decided to head to Sunfish Pocket for their meeting. Saito either waits for the next hour at Sunfish Pocket or heads there himself if he hadn't arrived yet.
• From 5:00 PM-6:15 PM:
  • Ota Matsushita spent his night traversing Akihabara, visiting many otaku and electronic shops. He purchased a brand new replacement phone in one of the stores.
  • Around 6:00 PM - Iris arrived at Sunfish Pocket and meets with Saito (in Renju), who explained the false offer to "work as hired talent for the special venue at Sunpoke." Iris seemingly refused, to which Saito offered to take her home.
  • 6:10 PM - A traffic collision occurred at Capital City Highway, Minato District, in which a negligent truck driver crashed into 5 other vehicles. Six people were injured, but only for minor injuries.
  • 6:15 PM - While walking around Akihabara, Ota headed to Sunfish Pocket and witnessed Iris and Saito leaving the establishment, getting into Renju's car, and drive away. Ota approached the cafe but leaves when he realizes it's closed. While in Renju's car, Saito drugged Iris and took her to the Kabasaki Chemical Plant.
• Around 7:00 PM-8:00 PM:
  • Iris was taken to the Kabasaki Chemical, was placed in the Prototype Psync Machine, and Saito (in Renju) Psynced with her, swapping bodies. Saito, now in Iris's body, proceeded to strangle Iris, in Renju's body, killing her. Saito then proceeded to take out Renju's eye and ate it.
  • Saito dragged and placed Renju's body inside a specially prepared oil drum, which is rolled over to Renju's car and placed in the trunk. Saito (in Iris) proceeded to drive back to Sunfish Pocket.
• During the entire nighttime (the following section is speculative):
  • Hitomi Sagan called So Sejima using a voice changer and blackmailed him for money, telling him to meet at Okiura Fishery Cold Storage Warehouse. Hitomi left her home and headed to the warehouse, where she took out Manaka's body and placed it on display in the warehouse. So, who had returned home from work, left his residence to meet with his blackmailer.
  • When he arrived, So found Manaka's body on display. Hitomi proceeded to call again and blackmail So with Manaka's body, and ordered him to not contact the police or the Kumakura Family. So returned home, and afterwards, Hitomi proceeded to hide Manaka's body back in the forklift.
• Around 8:00 PM - MPD released more information about Shoko Nadami's murder, which is broadcasted in radio stations. Following one of these broadcasts, the radio reported on the accident at Capital City Highway, including the arrest of the truck driver who caused it.
• From 8:13 PM to around 9:30 PM or later - Date and Mizuki arrived at Bloom Park, and investigated the back exit to the park. After some quick investigation, they learned that Renju's car passed through the abandoned tunnels and stopped at Bloom Park, making him a bigger suspect for the crime.
  • 8:50 PM - Ota continued his night around Akihabara. Saito, in Iris's body and driving Renju's car, stopped at a red signal nearby. Ota spotted "Iris" and approached him, asking if "Iris" has a license. Saito, worried that Ota would discover Renju's corpse in the back of the car, made him promise not to tell anyone that "Iris" was driving around without a license under the pretense of doing a favor for Renju.
  • 8:55 PM - Saito arrived at Sunfish Pocket. He took the elevator up with Renju inside the oil drum, recorded in the cafe's weight system. He created a pulley system above the bar, took out Renju's body from the oil drum, and hosted it in the air, not noticing that Renju's watch had fallen off inside the oil drum. Before leaving, Saito disabled all the security cameras in the cafe and erased all its footage.
• Around 10 PM - Date and Mizuki headed over to Renju's house, hoping to find him there. On the way over, Mizuki defended her father, claiming he would never kill her mom, while Date questions that line of thinking with evidence, such as the car footage and the recently hacked NILE message Renju's phone had sent to Mizuki. During their talk, Boss called and informs them that Renju had gone missing since his interrogation, and that the police could not find him at home. With nowhere else to go, Mizuki suggested that Renju could be at Sunfish Pocket instead, and so Date veered course over to the cafe.
• 10:20 PM - Date and Mizuki arrived at Sunfish Pocket, but once they entered the cafe, they found Renju's corpse hanging from the ceiling, a hook inside his mouth and his left eye missing.
• Around 11 PM - After Date and Mizuki found Renju's body, the first response team arrived at Sunfish Pocket. Mizuki was once again taken to the hospital for the night.

November 3rd

• 1:00 AM - A-set's late-night live-stream was scheduled to begin. Whether Saito, in Iris's body, decided to stream at night is unclear.
• Morning:
  • The Ujisaki golf tournament finished, and the Kumakura Family returned to central Tokyo, back to their offices.
  • Saito, as Iris, attended work at Lemniscate, doing recordings and podcasts all day long.
• 9:17 AM - The ABIS team met up at Boss's Office, where they discussed Renju's death and revealed to Date the previous Cyclops case from 2013. Date decided to return to Sunfish Pocket to investigate. Meanwhile, Mizukisnuck out of Central Hospital and hid in Date's car.
• Around 10:00 AM - As Date drove to Sunfish Pocket, he and Aiba spotted Mizuki hanging out in the backseat. At first, he considered taking her back to the Hospital, but Mizuki convinced him to have her tag along. Once Date agreed, they continued towards Sunfish Pocket as the pair discussed Shoko's involvement in an investment fraud scheme.
• 10:33 AM - Date and Mizuki arrived at Sunfish Pocket, where Kagami and the forensic team were still investigating. During the investigation, Date discovered Renju's watch inside the oil drum, the lack of security footage from the cameras, and the elevator's weight log history from the previous night. Date and Mizuki discuss the relevant people to the investigation, and they determine that they must speak with Iris and Ota, plus Date's informant Mama. They choose to head to Matsushita Diner, Lemniscate, and snack bar Marble as possible locations to investigate.
• Approximately 11:30 AM - Date and Mizuki visited Matsushita Diner looking for Ota, but Mayumi told them that Ota had left for the day. They headed out and continued investigating.
• Approximately 12:45 PM - Date and Mizuki arrived at Lemniscate and spoke with the receptionist, Ritsuko Enshu. She informed them that "Iris" is recording a podcast and can't be interrupted. Date gave Ritsuko his contact info and asked to call him in case Ota stopped by the office.
• Early in the Afternoon - So Sejima stopped by the Kumakura Office in the afternoon to speak with them regarding some business.
  • (Currently speculative) - So visited the Kumakura Family in response to Hitomi's blackmail, despite her insistence to not contact them. So remained at the office to discuss it, smoking Klein cigarettes.
• Approximately 2:00 PM - Date and Mizuki dropped by Marble, while Mama was taking a break. The two of them discussed Renju's visits at Marble, and the conditions for which Date and Mizuki had them living together, while a radio broadcast speaking about last night's Capital City Highway accident was played.
  • Mama returned to her station behind the bar, and she discussed with Date and Mizuki about Renju's secret lover, who had gifted him the watch, as well as Renju's past connections to the Kumakura Family. Once he realized that he must head to the Kumakura Office to investigate further, Date pretended to head to the bathroom, called Boss to have someone pick up Mizuki at the bar, and headed alone (with Aiba) towards the Kumakura Office.
• 3:22 PM - Date arrived at the Kumakura Office, where Moma, Chinpei, and Dokuta were hanging out, while So Sejima hid in the back room. After knocking down Chinpei and Dokuta, Date asked Moma some questions about Shoko and Renju.
  • Moma resisted his questions, so Aiba used her X-ray function and spotted someone's silhouette (So) on the other side of the nearby door. When Date attempted to investigate, Chinpei retaliates, and a shootout ensues inside. Aiba and Date manage to defeat Chinpei and Dokuta once more, and So revealed himself to the Special Agent.
  • Date questioned So and Moma, obtaining their alibis from their previous nights, delving into the connections they had with each other and with Shoko & Renju, and they briefly discussed the Kumakura family history and the hospitalization and eventual death of Rohan Kumakura.
    • (Speculative): So lied about his alibi, stating that he was home all night after arriving from work, when he had been blackmailed by Hitomi at Cold Storage Warehouse.
  • Once his investigation finished, Date got a phone call from Ritsuko, who stated that Ota had just arrived at Lemniscate. Date headed to Lemniscate to speak with him.
• From 3:00 PM onwards - A new MPD recruit stopped at Marble to pick up Mizuki, under Boss's orders. She took Mizuki home for the day. The recruit stayed with her for a while, but after some time, Mizuki told her she's free to leave, promising to check up with her later.
• Around 5 PM - On the drive to Lemniscate, Date and Aiba discussed the situation regarding the Kumakuras. They brought up So's past living in the Kabasaki District, and the scandal involving the chemical plant explosion from 8 years in the past.
  • Detective Akasaka called Date and informed him of the phone call Investigation HQ had received the previous day from #89. He played a recording of the phone call, which stated that more bodies would drop. Akasaka stated that the phone call came in before they had found Renju's body, meaning that #89 seemingly knows something about this mystery.
• 5:59 PM - Date arrived at Lemniscate and spoke with Ota. At first he was reluctant, but after Date put some pressure on him, Ota revealed that the previous night he had seen "Renju" and Iris leave Sunfish Pocket. Soon after, Saito (in Iris) walked out of her podcast, and with the new circumstances surrounding her lack of alibi, Date took "Iris" to Headquarters.
• 8:23 PM - Date began his interrogation of Saito (in Iris) at the Interrogation Room. Saito attempted to play off his knowledge of the events and of Sunfish Pocket, and gave an alibi that can't be corroborated, due to Hitomi not being home the previous night.
  • Date laid down the evidence regarding Renju's murder, such as how "Iris" could have murdered Renju by drugging him, used the oil drum to transport the body, and that the weights in the elevator matched Iris's weight.
  • During the entire interrogation, Saito kept in communication with Ota via NILE messages using Iris's phone under the table. Ota promised to keep their encounter last night by Renju's car a secret, but Aiba and Date noticed Saito using the phone from the security cameras and the mirror. With the secret messages exchanged mid-interrogation, Boss gave Date permission to Psync with "Iris".
• Around 9:00 PM - Date began to Psync with Saito, whom he assumed was Iris. Date and Aiba found themselves inside an empty abandoned room they didn't recognize.
  • After hitting the side of a CRT TV, the pair began seeing various drawings of animals being mutilated, found across numerous television monitors, as Date and Aiba replicated each of the animal murders. At the very end of the Psync, they witnessed a blue figure kissing what appeared to be So Sejima.
  • After the Somnium, the ABIS team wondered why So Sejima suddenly appeared in "Iris's" dream. Date asked "Iris", but Saito lied about not knowing So. Date called Ota to ask about the NILE messages he exchanged with "Iris" during the interrogation, but Ota demanded Date to release Iris and meet with him to discuss those further.
• 9:46 PM - Date arrived with Saito (in Iris) at Matsushita Diner. Ota waited in the diner while Mayumi was resting in the back. Date asked him about the NILE messages he exchanged with "Iris", but Ota tricked him to look at a family photo, hitting him from behind with a wok, knocking Date unconscious.
  • Awoken by the commotion, Mayumi headed to the front of the diner, where she encounters "Iris," Ota, and an unconscious Date. Aiba records footage from an inconvenient angle of Saito approaching Mayumi and taking the flower knife from her hands, while Ota was preparing the Matsushita van. Ota and Saito leave the diner, but Mayumi soon chases after them hailing a taxi driven by Takushi Ibarado.
• From around 10:00 PM to 11:00 PM:
  • Around 10:00 PM - Ota and Saito (in Iris) drove from the Diner all the way to Fuchu City, with Mayumi and Takushi close to their tail. Once they're near Fuchu, Saito asked Ota to stop at a convenience store to buy a drink.
  • 10:32 PM - Ota stopped at a FamiSto in Fuchu to buy "Iris" a drink. Takushi parked the taxi at a nearby 8-12, but Mayumi suddenly lapsed in her memory and wandered inside the store to buy some Odoroki-man chocolate. With Ota inside the FamiSto, Saito took the van and drives back to central Tokyo.
  • 10:33 PM - As Mayumi bought the chocolate, Ota stole a nearby station wagon and attempted to pursue his van. Takushi quickly called for Mayumi to return to the taxi, and they promptly followed the van. Ota eventually lost track of the van, but Mayumi and Takushi remained on its trail.
• 11:00 PM-11:10 PM - Saito, in Iris's body, arrived at the Sejima Residence and asked to speak with So Sejima. Some unknown words were exchanged between father and "daughter"/son, and during that interaction, Saito is able to convince So to let him take him somewhere in the van.
  • Mayumi and Takushi followed behind the van and waited outside the Residence once they arrived. When the van pulled out of the residence, the pair resume their chase.
• 11:40 PM - Saito (in Iris) drove So to the Kabasaki District. They reached the abandoned factory, at which point So was already drugged and unconscious.
  • Takushi and Mayumi followed suit, but once Saito drove into the restricted Kabasaki District, Takushi stopped at the edge and refused to enter any further. With nothing to do, the pair wait at the entrance to the district in the hopes that their target would exit through the same path.

November 4th

• Around Midnight to 12:25 AM - Saito, while in Iris, placed So inside the Prototype Psync Machine. He psynced with him, and the two swapped bodies. Saito, now in So's body, took So, now in Iris's body, and placed him in the van to drive out.
  • 12:25 AM - Saito left the Kabasaki District and headed towards the Warehouse District. Mayumi and Takushispotted the van leaving Kabasaki and continued their pursuit.
• Around 1:00 AM - Saito, in So, arrived at the Cold Storage Warehouse and began prepping for the murder. He took out a computer and camera, prepped the ice-cutting machine, and put on a Polar Bear costume. He proceeded to place So, in Iris, at the table in front of the ice-cutting machine.
  • The taxi arrived at the Warehouse District, and Mayumi got off immediately and reached the warehouse on foot. She witnessed "a polar bear" preparing the murder before her. Mayumi ran away, dropping her chocolateby accident.
• Until 3:00 AM - Ota continued to search for his family van, having lost it. After many hours searching by car, he stopped at a net cafe and used a computer to track the GPS on his phone, which he had left in the van. Using that signal, he headed towards the Warehouse District.
  • Around 2:30 AM - Date woke up alone at the Matsushita Diner. His head hurting, he headed out in his carand began searching for Iris and Ota.
  • 2:50 AM - While Date drove, Boss called Date and told him that a livestream had just begun: an unconscious "Iris" laid at a table with an ice-cutting machine above, left eye missing. Date headed straight towards the Warehouses, which Aiba noted was 20 minutes away.
• 3:15 AM - Saito, inside a polar bear suit, activated the ice-cutting machine live on stream to kill So, inside Iris. Date, Aiba, Boss, and presumably others like Mizuki watched the saw-blade drop downward.
  • However, just in time, Ota appeared and turned off the machine, and began fighting Saito off-screen from the stream. During the scuffle, Ota manages to injure Saito's leg with a crane, which made Saito drop the flower knife near his pool of [So's] blood. Ota approached the knife and recognized it as his mother's, and during the confusion, Saito quickly picked up the knife and stabbed Ota, making him collapse on top of So's pool of blood.
  • 3:17 AM - Date arrived at the warehouse, and Saito fled the scene. After making sure that Ota and "Iris" were alive, he chased after the culprit, but Saito, in So, had gotten away.
• Around 3:30 AM - Ota and So, in Iris, were taken to Central Hospital, where they were both placed in surgery overnight.
• Around 4:00 AM - Hitomi was woken up by police officers, who took her to Central Hospital to see "Iris." The same occurred for Mayumi, who had recently returned home, to visit Ota.
  • Once Hitomi was informed that Iris was alive, she collapsed from exhaustion and was taken to one of the nearby rooms.
• 9:34 AM - Date and Boss discussed the events of last night: the fleeing killer, Ota and "Iris's" recovery, how Hitomi remained at the hospital while Mayumi headed home to collect Ota's things for him. They also discussed Renju's relation to the warehouse, and the events witnessed inside "Iris's" Somnium. Date headed out to investigate.
• Approximately 10:30 AM - Date and Aiba arrived at the Warehouse District and investigated the crime scene. They discovered the van and the station wagon in front of the Cold Storage Warehouse, the streaming equipment left inside by the culprit, and the chocolate that was dropped by Mayumi. Aiba informed him about the warehouse's ownership and its relation to Renju.
• Approximately 12:00 PM - Date visited Matsushita Diner to speak with Mayumi, but after attempting to hold a conversation with her, he and Aiba realized that Mayumi suffers from dementia. Five years ago, her diner had closed down and her husband had passed away, yet she remembers none of it. Date headed out of the diner and continued to investigate.
• Approximately 1:15 PM - Visiting the Sejima Residence, Date asked Saito, in So, for an alibi of the previous night's events. Saito lied and claimed he was home the entire night, and he denied any connection to either Iris or the Kumakuras. His bodyguards threatened Date from taking any action against "So" without a warrant, and so Date departed.
• Approximately 2:30 PM - Date went to the hospital and found Hitomi in one of the rooms. She recounted the time when her friend, Manaka, was murdered, and how similar it felt when she learned about Iris the previous night. Date debated to himself the chances for which she could be the culprit of the current case.
• Approximately 3:45 PM - Date headed home to check on Mizuki. He apologized to her for leaving her at Marble alone with Mama. Mizuki told him about the history of the Okiura Fishery, as well as her grandpa's supernatural strength. Mizuki asked to investigate with him, but Date refused. He recalled the events of a year ago, where he trained Mizuki and uncovered her hidden strength, and soon after left to continue investigating.
• Around 5:00 PM - As Date drove to Headquarters, Aiba discussed with him the lack of connections between all the various points of interest in the case. She revealed that Mayumi's fingerprints were on the chocolate found at the latest crime scene. Boss called Date to head to Central Hospital to interrogate the recently awoken Ota.
• 5:42 PM - Date and Boss interrogated Ota at the Hospital. He explained his actions the previous night, and revealed that he saw "Iris" driving Renju's car on the night of November 2nd. Aiba used X-ray on Ota, discovering that he was hiding a knife at his bed. Date restrained Ota, and Boss knocked him out with sleeping gas. She suggests to Date to take Ota to the Psync Machine to Psync with him.
• 8:15 PM - Date psynced into Ota's Somnium, where they saw Ota act as a Kamen Rider superhero fighting off the Polar Bear. Aiba and Date aided in Ota's battle against the Polar Bear in order to save Iris.
  • In the Somnium, Ota was led to the red shelf, and managed to use a crane to injure the Polar Bear's leg. Date attempted to stay past the 6 minute limit to see the killer's identity, but Ota was stabbed, ending the dream.
• 8:21 PM - Boss reprimanded Date for his actions in the Somnium, warning him about overpassing the limit. They questioned Ota, and he remembered injuring the culprit in real life. Soon after, Date fell unconscious from strenuous effects from the Psync.
• Rest of the Night:
  • Date was taken to his home by Boss and Pewter, where Mizuki was. The pair told her about the new developments in the case before leaving Date in her care.
  • Ota was taken back to the Hospital to rest.

November 5th
