      Bodyguard: We told you, you can't come in here!
      Bodyguard: You can't do what you want just because you're a cop.
      Bodyguard: You're trespassing. That's a crime, you know.
      Bodyguard: Get lost.
      No use pushing it.
      If they called HQ, we would get arrested for sure.
      And what would happen to Iris...?
      Who would protect her?
      Naix is a huge organization. They have people everywhere.
      I can't risk being caught. Then I wouldn't be able to save Iris.

      Date icon.png Date: This is definitely where the smell is coming from.
      Aibear icon.png Aiba: (Is there something inside?)

      Date icon.png Date: The left eye is hollowed out...
      Aibear icon.png Aiba: (This is most likely a crime committed by the New Cyclops Killer.)
    2. Date icon.png Date: Do you have an estimated time of death?
      Aibear icon.png Aiba: (Today, some time between 11:00am and noon.)
      Date icon.png Date: That's about when I was talking to Ota at Matsushita Diner...
      Aibear icon.png Aiba: (At that time, Mayumi was in police custody and Iris was in the ICU of Central Hospital.)
      Aibear icon.png Aiba: (They have not moved.)
      Date icon.png Date: That means Ota, Mayumi, and Iris couldn't possibly have committed the crime.
      Date icon.png Date: Assuming that this is the work of a single killer, those three can be eliminated from the list of suspects.
      Aibear icon.png Aiba: (Ota, Mayumi, and Iris are not the New Cyclops Killer.
      Date icon.png Date: Right.
    3. Date icon.png Date: By the way, why is there no one in the mansion?
      Date icon.png Date: No bodyguards, no housekeepers...
      Aibear icon.png Aiba: (I do not know.)
      Date icon.png Date: Does So have family?
      Aibear icon.png Aiba: (So Sejima's wife died in labor 30 years ago giving birth to their son.)
      Aibear icon.png Aiba: (Their son is currently living abroad.)
      Date icon.png Date: So lived here alone?
      Aibear icon.png Aiba: (Do you find that suspicious...?)
      Date icon.png Date: No just...
      Aibear icon.png Aiba: (Date, a call from Pewter.)
      Date icon.png Date: Connect me.
      Pewter icon small.png Pewter: Date, the Psync machine is up and running!
      Pewter icon small.png Pewter: You can Psync with Mayumi now.
      Date icon.png Date: Oh, thanks, Pewter...
      Date icon.png Date: But there are more pressing matters now.
      Pewter icon small.png Pewter: Did something happen?
      Date icon.png Date: Yeah. I found So Sejima's body.

      Pewter icon small.png Pewter: What?!
      Date icon.png Date: I'm at the Sejima household.
      Date icon.png Date: Send the investigation team over.
      Pewter icon small.png Pewter: I can answer your questions when I get back to ABIS.
      Pewter icon small.png Pewter: Got it!
      Aibear icon.png Aiba: (Date, what is your plan?)
      Aibear icon.png Aiba: (Wait until Crime Scene Investigation arrives?)
      Date icon.png Date: No, there's something I need to do.
      Date icon.png Date: If that taxi driver was telling the truth, Mayumi was at the warehouse yesterday.
      Date icon.png Date: And we know the chocolate we found at the scene was hers.
      Date icon.png Date: Maybe she saw something. Maybe she knows something we don't.
      Date icon.png Date: Some kind of clue or information about the culprit.
      Aibear icon.png Aiba: (Then...)
      Date icon.png Date: Yeah. We're going to Psync with Mayumi.

  • Trivia

    • On Day 5: Tuesday -dakkAI-:
      • If you examine the Topiary, Date will think to himself that it's a blob, and that aligning 4 of them together would make them disappear, before correcting himself. This is a reference to the Puyo Puyo video game series, in which colored blob creatures named "Puyo" fall on a grid, and aligning 4 of the same color make them disappear, moving the remainder downwards.[1]
      • If you examine the Island, Date will mention how "Small Island" sounds like "Kojima" in Japanese, at which point Aiba becomes excited at hearing that The Director Kojima was present. When she realizes he's not here, she exclaims "It honestly wouldn't be that weird for him." This is a reference to video game creator and director Hideo Kojima, famous for his eccentric style of game direction and storytelling, as featured in games such as Metal Gear Solid and Death Stranding.[2]
    • Out of all the locations featured in the video "A-set Reservations Unknown", the Sejima Residence was the only one not properly introduced by name.
