Three Months Later: kassAI, while visiting Boss's Office:

Day 2: saikAI, during the 9:21 AM investigation segment:
An electronic darts game. Date: Why do you have this? Boss: So if we're trapped down here when World War III starts, we'll have something to do.
Date: (Maybe if you get a high score, you get a clue...) Aiba: (Do you really think that is the case?) Aiba: (This isn't an escape room.)
Day 4: syuurAI, during the 9:32 AM investigation segment:
An electronic darts game. Boss: So the darts board has all these holes, and the tip of the dart goes in, right? Boss: It's kinda sexual, don't you think? Aiba: I do not understand. What is sexual about it? Date: You don't wanna know.
Three Months Later: kassAI, while visiting Boss's Office:
An electronic darts game. Iris: Cheer me on, okay? Iris: Here I go! Iris: One, two, three! Boss: Throw!
Day 2: saikAI, during the 9:21 AM investigation segment:

Day 4: syuurAI, during the 9:32 AM investigation segment:
A soccer ball Boss: I've been wondering... Boss: Which balls are bigger, yours or this soccer ball? Date: The soccer ball, obviously!
Three Months Later: kassAI, while visiting Boss's Office:

Day 3: gyoukAI, during the 9:37 AM investigation segment:
Boss: Looking at that reminds me of my old boyfriend from high school... Date: You said that about the soccer ball yesterday. Boss: Oh, that just reminded me of his balls. Because of the size, you know? Date: That sounds like a serious medical condition.
Day 4: syuurAI, during the 4:06 PM investigation segment:
A volleyball. Pewter: Spiking is an important part of volleyball. Pewter: Hm. Spiking...spike...spikechun? Date: What is that?
Three Months Later: kassAI, while visiting Boss's Office:
It's a volleyball. Boss: Volleyball... Boss: "Volley" reminds me of a valley, like cleavage. And of course, "ball" is self-explanatory. Boss: Isn't it kind of dirty? Date: No, it isn't! Date: There's nothing dirty about volleyball! Boss: Don't get mad at me... Iris: There's nothing AO about volleyball!
Day 2: saikAI, during the 9:21 AM investigation segment:
Boss: Overall length of 15.35 inches, width of 8.8, height of 5.35, and a body weight of just a hair over 830 grams. Boss: This RC car has friction dampers on the front and rear axles as well. Date: Uh, how do you know all this stuff? Boss: I used to be a flag girl for RC car racing in my glory days.
Date: (I know! Boss must be radio controlled!) Date: (She's a robot who was programmed to show up at Hitomi's house!) Aiba: (Date...calm down.)
Day 4: syuurAI, during the 9:32 AM investigation segment:
A remote-control car. Boss: Ah, if only I could control you with a remote. Boss: Make you do this, make you do that...
Three Months Later: kassAI, while visiting Boss's Office:
An RC car. Boss: That RC car kind of reminds me of Date's car... Hey, Iris. Iris: Yeah? Boss: What's the deal with you and Date? You still into him? Iris: Hahahaha, no.
Date: (Maybe she was a fisherman in a past life!) Aiba: (Why would that matter...?)
Day 3: gyoukAI, during the 9:37 AM investigation segment:
A flag with "Big Catch" on it. Boss: It's good luck, you know? Boss: Whether it's catching fish or catching criminals.
Day 4: syuurAI, during the 4:06 PM investigation segment:
A flag with "Big Catch" on it. Boss: Wait a minute, did you let #89 escape on purpose? Boss: So that you could catch the bigger fish? Pewter: Y-Yeah, Boss! Exactly! Boss: I was kidding...
Three Months Later: kassAI, while visiting Boss's Office:
A flag with "Big Catch" on it. Iris: Where did you get that? Boss: Oh, you haven't heard? Boss: Starting next year, that's going to be the official flag of Japan. Iris: Wow, really?
Day 2: saikAI, during the 9:21 AM investigation segment:
Boss: I can't live without coffee. Boss: I love it smooth and dark. I'm always amused by Boss's ability to make anything sound dirty. I wonder if she does it on purpose.
Date: (Boss drinks her coffee black...) Date: (It must be a symbol of her black heart!) Aiba: (You have cracked the case wide open.)
Day 4: syuurAI, during the 9:32 AM investigation segment:
A coffee maker. Boss: There's something about a man who likes his coffee black. Boss: Black coffee puts hair on your chest. Date: Does it now? Boss: And somewhere lower... Aiba: I understand. You are referring to Date's leg hair. Aiba: It is quite prominent.
Three Months Later: kassAI, while visiting Boss's Office:
Boss: Coffee maker... Boss: Coffee? Beans? Brewing? Hm... Boss: Damn, I can't think of any more dirty jokes! Date: Who are you talking to?
Date: (Maybe something is inside this shogi piece?) Aiba: (I looked with the X-ray mode but did not discover anything.)
Day 3: gyoukAI, during the 9:37 AM investigation segment:
It's a "King" shogi piece. Boss: Do you know why shogi pieces are pentagons? Boss: So that every shape is equal. Boss: It makes everything fair. Date: Is that right? Boss: Maybe, I just came up with that right now. Date: You made it up!
Aiba: I know why shogi pieces are pentagons. Aiba: In chess, you can distinguish your pieces from your opponent's by colors. Aiba: White and black. Aiba: But in shogi, the pieces are the same color. Aiba: Why is that? Aiba: Because you can use your opponent's pieces as your own. Aiba: Therefore, you cannot color-code them. Aiba: Instead, your pieces are determined by the direction they are facing. Aiba: The irregular shape makes it easy to determine orientation.
Day 4: syuurAI, during the 4:06 PM investigation segment:
It's a "King" shogi piece. Boss: A shogi player gave that to me. Boss: I think his name was Hanyu? Pewter:The Hanyu? Boss: Yup, that's him.

Boss: You think it's true that a tanuki's ballsack can stretch up to 10 square feet? Date: Yeah, I-I-I wouldn't know...
Date: (Boss loves her wine...) Date: (Maybe she got drunk and went to Hitomi's house for some reason.) Aiba: (You sound drunk yourself.)
Day 3: gyoukAI, during the 9:37 AM investigation segment:
A wine bottle. Boss: I'm a sucker for white wine. Boss: Shame you don't have an eye for it. Date: I have a right eye. Aiba: And a left.
Day 4: syuurAI, during the 4:06 PM investigation segment:
A wine bottle. Boss: Date, Pewter. Once we're done here, let's pop that bottle. Date: Not a bad idea. Pewter: But when the Boss gets drunk, she has the tendency to crush balls... Aiba: (In that case, perhaps we should never solve this case...)
Three Months Later: kassAI, while visiting Boss's Office:
There are wine bottles lined up. Date: Hey, Boss. Didn't you say that once this case was settled, you were gonna open up that bottle for me? Boss: No, I didn't. Date: Yes, you did! Boss: Did not. Date: Why are you lying about this? Boss: Because I don't want anyone to drink my wine. Boss: That wine is mine, bottom line. Date: You can't get out of your promise with a rhyme!
Day 2: saikAI, during the 9:21 AM investigation segment:
Date: (Damn it, Boss, hiding something from me...) Date: (I could beat her over the head with that tombstone.)
Day 3: gyoukAI, during the 9:37 AM investigation segment:
A tombstone. RIP. Boss: That means "Rest In Peace." Boss: As in, sleep peacefully. Date: Who's it for? Boss: Ma, from the host club.
Aiba: "RIP" specifically refers to the Latin phrase "Requiescat in Pace." Aiba: Boss is correct about the general meaning.
Ma's tombstone, I guess.
Day 4: syuurAI, during the 9:32 AM investigation segment:
Ma's tombstone.
Three Months Later: kassAI, while visiting Boss's Office:

Day 2: saikAI, during the 9:21 AM investigation segment:

Day 4: syuurAI, during the 9:32 AM investigation segment:
A pumpkin carved like a Jack-o-lantern. Boss: Where should I put old Jack here? Aiba: I thought his name was "Bill"? Date: ...

Day 2: saikAI, during the 9:21 AM investigation segment:
Boss: That's a Persian rug, you know. Very expensive. Date: Oh yeah? How much? Boss: Ten billion yen. Date: What are you, in elementary school?
Maybe there's a clue under the rug... I lifted up the rug but didn't find anything other than a few homoerotic manga.
There's nothing under there but gay manga.
Day 4: syuurAI, during the 9:32 AM investigation segment:
There's a nice rug here. Boss: Under no circumstances are you allowed to look under this rug! Boss: Do you understand?! Date: What have you got under there?

Somehow, I knew... There's dirty, gay erotica hidden under that rug...

Day 2: saikAI, during the 9:21 AM investigation segment:
Boss: That's my grandpa's death mask. Date: The guy had a huge face!
It's Boss's grandfather's death mask.
Day 4: syuurAI, during the 9:32 AM investigation segment:

Three Months Later: kassAI, while visiting Boss's Office:
A mysterious mask is displayed on the wall. Boss: Kuranushi... Boss: Poor Grandpa Kuranushi! Boss's mental health is still in question.
Date: Have you always been down here? Date: Maybe you've overheard some of Boss's secrets... Figure: ... No answer. Keeping quiet, eh? Date: Maybe I'll Psync with you. Aiba: (Date, if you don't take this more seriously, I will end you.)
The figure is maintaining the right to remain silent.
Day 3: gyoukAI, during the 9:37 AM investigation segment:
A plaster figure. Boss: That's my boyfriend from about 10 years back. Boss: We had a bad breakup, so I sliced his head off and coated it in plaster. I know that she's joking, but I also know what Boss is capable of...
Boss's former lover...

Date: Reminds me of you, Boss Date: You have many faces, one inside the other. Date: No matter how deep you go, you'll never get to the real you. Boss: Matryoshka's eventually end, though. Boss: You get to the last one, the smallest one, like a child... Boss: That's the real me.
I opened the matryoshka. There was a smaller one inside.
I opened the matryoshka. There was a smaller one inside.
I opened the matryoshka. There was a smaller one inside.
I opened the matryoshka. There was a smaller one inside.
I opened the matryoshka. Inside was a strip of paper saying, "Not A Winner. Too Bad!" Date: (It's mocking me...) Aiba: (Don't blame the matryoshka for your stupidity.)
There were no clues inside the matryoshka.
Day 4: syuurAI, during the 9:32 AM investigation segment:

Day 2: saikAI, during the 9:21 AM investigation segment:
Boss: Like it? It reminds me of you, Date. My name is Kaname. The kanji for "key" can be read as "Kaname." But that's not my real name. I don't know my real name. I don't know anything about myself past six years ago...
Date: (I got it! I found it!) Date: (This must be the "key" to solving the mystery!) Aiba: (Good work, Date. Now you only need to find the giant keyhole.)
Maybe it isn't relevant...
Day 4: syuurAI, during the 4:06 PM investigation segment:
It's a large key. Pewter: But no keyhole for it. Pewter: Same as you, Date. Date: What do you mean by that?
Day 3: gyoukAI, during the 9:37 AM investigation segment:
Date: Hey, Boss. Why are you always sitting on top of the desk? Boss: Because I like to be on top of my work. Aiba: You sit that way on the off chance you get the opportunity to use a pun?
Day 4: syuurAI, during the 9:32 AM investigation segment:
Boss's chair. Boss: Y'know, the kanji for "chair" comes out to "strange mushroom." Boss: Makes me think of a man's "strange mushroom," if you know what I mean. Date: Seriously, is that the only thing you can think about right now?
Day 4: syuurAI, during the 4:06 PM investigation segment:
Boss's chair. Pewter: I really like chairs. Pewter: They look delicious. Date: (What the hell are you talking about?)
Three Months Later: kassAI, while visiting Boss's Office:
Boss's chair. Iris: Hey, Boss. Can I sit in your chair? Boss: No. It's my chair.
Day 3: gyoukAI, during the 9:37 AM investigation segment:
Boss: That was a piece of evidence in a case about eight years ago. Boss: A mathematics teacher used it to stab her boyfriend when she found out he was cheating on her. Aiba: The triangular ruler must have come in handy for solving that...love triangle. Date: Booo...
Day 4: syuurAI, during the 9:32 AM investigation segment:
A triangular ruler. Boss: Did you ever use to play with these rulers like a gun when you were in elementary school? Date: I don't know. I don't have any memories from back then, remember?
Three Months Later: kassAI, while visiting Boss's Office:
Iris: I had no idea you guys had B-2 stealth bombers in here! Date: That's a ruler...
Day 2: saikAI, during the 9:21 AM investigation segment:
Boss: The battery died on that thing, so the hands have stopped. Boss: Like you and me. Date: What do you mean? Boss: *sigh* Oh, Date...
Date: (Maybe this clock means something...) Aiba: (Like what?) Date: (...) Aiba: (I would appreciate it if you exercised thought before opening your mouth.)
Day 4: syuurAI, during the 4:06 PM investigation segment:
There's a clock off to the side of her desk. Pewter: If you had the power to stop time, what would you do? Date: Do you even have to ask? Aiba: (Your heart rate is increasing rapidly.)
Three Months Later: kassAI, while visiting Boss's Office:
There's a clock off to the side of her desk. Boss: Iris, if you had the ability to stop time, what would you do? Iris: Hm, let me think... Iris: I want to catch a skyfish!
Day 3: gyoukAI, during the 9:37 AM investigation segment:
It's a floaty... Date: Why do you have that here? Boss: We're six floors underground, right? Boss: What if it rains? We might get flooded. Aiba: I don't think a floaty would save us in that predicament...
Day 4: syuurAI, during the 9:32 AM investigation segment:
It's a floaty... Boss: Consider it a good luck charm. Boss: So you don't drown when you Psync.
Three Months Later: kassAI, while visiting Boss's Office:
It's a lifesaver... Iris: Oh, donuts sound good right about now... Boss: Oh, me too! Me too!

Trivia[]
General[]
-AI- The Somnium Files- Unused Item Dialogue - Boss's Office
The Office contains unused dialogue for 3 items that never appear in the room: a Baseball Bat, a Gourd Doll, and a Vuvuzuela. You can hear the audio for these unused lines in this video.
References to Media and Pop Culture[]
In the chapter Day 4: Monday –syuurAI–, if you examine the Volleyball during the investigation segment where Pewter is present, he'll mention that the act of spiking is an important aspect of Volleyball, followed by him saying, "Hm. Spiking...spike...spikechun?" The name "Spikechun" is a common abbreviation of Spike Chunsoft, the video game company that developed AI: THE SOMNIUM FILES.
In the chapter Day 2: Saturday —saikAI—, if you examine the Skis, Boss will ask Date if he's heard of "the murder case at the resort called Spur." This is a direct reference to the series of murders that occurs at the ski lodge named "Spur," located in the mountain range of Shinsho (Nagano), within the 1994 video game Kamaitachi no Yoru (localized as "Snowflake Inn" in Banshee's Last Cry), developed by Chunsoft years before its merger with Spike to become the aformentioned Spike Chunsoft.
Within the game's code, there is hidden unused dialogue for interacting with the Skis on Day 2: Saturday —saikAI—. The full unused conversation with Boss goes as follows:
Narration: Skis.
Boss: "Are you familiar with the murder case at the resort called Spur?"
Boss: "That pole there was the murder weapon."
The line most likely goes unused due to the ski pole not being visible among the skis and the other items within the room. However, the line itself is a proper reference to the events of Ending 11 —one of the Bad Endings— of Kamaitachi no Yoru, where the protagonist is attacked and killed with a ski pole. This would suggest that, if this unused line were to be taken as canonical, then the following events are canon within the universe of AI: THE SOMNIUM FILES:
Kamaitachi no Yoru (Banshee's Last Cry) spoilers here!
In Ending 11, all of the characters in the story are killed except for Mikimoto (Faberge) and Mari (Grace). The majority of the cast is killed in their default death scenario against Mikimoto. Haruko (Amber) is killed by Mikimoto in the hallway. Toru (Max), the protagonist, seeks out the three OLs assuming one or all three must be the killer, telling his girlfriend Mari to lock her room and to wait for him to return. When Toru knocks at their room, he is greeted by Kanako (Tiffany) attacking him with the ski pole in question, piercing his shoulder. Toru fights back in self-defence with his mop in hand, crushing her skull and killing her. Inside the girls' room, he finds Keiko (Debbie) and Aki (Molly) already dead, presumably killed by Mikimoto, and when Toru turns around, he finds Mari watching him in shock. Believing Toru was the true killer in the end, Mari stabs him in the neck with the ski pole, killing him. Mari's fate is undetermined, as it is unclear if she was able to fend off against Mikimoto like in other endings or if she was ultimately killed by him. The murders are eventually investigated by the police, and the skis and the supposed ski pole find themselves from Shinsho/Nagano all the way to Boss's Office.
The police poster located behind Boss's desk contains an icon at the bottom right corner. The icon is of the mascot character Usami, from the game Danganronpa 2: Goodbye Despair.[1]
The life-sized police doll Mario (鞠夫, Mario) is most likely a reference to a short-story/novel series known as the Mario series (鞠夫シリーズ) and/or the Doll series (人形シリーズ). The story revolves around the ventriloquist Yoshio Tomonaga and his split-personality Mario Marikoji, the latter of which is manifested as Yoshio's doll and who acts as a detective that solves crimes. The books were written by Takemaru Abiko, who is also known as the scenario writer for Kaimatachi no Yoru, the game mentioned earlier in this Trivia section.[2]
In the chapter Day 3: Sunday -gyoukAI-, when you examine the Mask (Left), Boss will say that spikes come out of the mask if you put it on and Date will say that it sounds familiar. What's more, in the chapter Three Months Later -kassAI -, Iris says that she wants to wear the mask and Date replies by saying that if she wears it and gets her blood on it, she will turn into a vampire. This is a reference to the Stone Mask in Jojo's Bizarre Adventure, which can turn someone into a vampire if the person wears it and pours blood on it.
Boss: *whooo*...
Date: Stop ogling me.
Boss: *whooo*...
Iris: Hm, let me think...
