Dialogue

Prologue

(Idle)
Strange Man: W—Wait!
Cold Bangboo: Did you need something, citizen?
(Interact with the man and Bangboo near the NEPS building)
Strange Person: Wait, don't leave yet! Just hear me out!
A strange man stops a Bangboo on its way back to Public Security... He seems to be familiar with the Bangboo.
Icon Dialogue Commission (Wait and see what happens)
(Continue commission)
Icon Dialogue Talk (Don't get involved in PubSec affairs)
(Exit dialogue)

Strange Person: Seriously? You don't remember me? We're buddies, you know?
Indifferent Bangboo: Executing the command "remember"... Execution complete. Conclusion: I don't know you. I'm North, a Bangboo working for the Lumina Square Precinct of Public Security. You're just a regular citizen passing by.
Strange Person: No way! I'm not just some regular citizen passing by! I'm Rost! Your one and only pal! Your best buddy ever!
North: Unfortunately, my memory logs don't have a match for a "best buddy ever." How can I assist you? If you need help, I can accompany you to Public Security...
Rost: No, no! Don't go to Public Security. Not me, it's you who can't go! Okay, you have an activity log, right? Check your actions from 11:21 AM today, and you'll understand what I mean! A good friend wouldn't lie to you!
North: In response to this citizen's request, I'm now accessing my operation logs from 11:21 today... Access... failed... The record shows that at 11:21, I was... dead?
North: "Dead" is a biological term for organic life, not for Bangboo. Why is there a record of an incorrect log? Cognitive retrieval failed... Illogical content detected... Unable to comprehend...
The Bangboo's tone is strange, not like the usual service-oriented ones.
Rost: Look, it's alright if you don't understand! Just trust me and don't go to Public Security. They'll subject you to a thorough inspection, and you'll probably get... formatted or something, and your logs will be erased for sure! Then you'll never uncover the truth about your "death"!
Rost: Trust me! Even if the whole world lies to you, I would never do anything like that! I'm here to save you, buddy! And... look at this! I've found this "Memory Detective" on Inter-Knot!
Icon Dialogue Talk (Oh? A detective from Inter-Knot?)
Icon Dialogue Talk (A detective? Where?)
Rost: Don't underestimate (‍himhim / herher‍) as just a stylish young kid; (‍hishis / herher‍) methods are extraordinary! (‍He'sHe's / She'sShe's‍) a famous young detective on Inter-Knot! *winking at you*
Icon Dialogue Talk Wait... are you talking about me?
Icon Dialogue Talk Huh? What does this have to do with me?
Rost: That's right, no need to hide your identity, great detective. You're among friends! *winking at you*
Rost: Listen up, North. With the detective's help, we'll soon find your missing logs and uncover what really happened at 11:21. Just give us a bit more time! It's alright to hold off going back to Public Security for a few days, right?
Rost: Trust me! You might not remember anything now, but once your memory is fixed, you'll see that I'm doing my best to help you, North, old buddy!
North: Okay, tracking down the reason for the erroneous record is a necessary step. I'll hold off on returning to Public Security and wait for your and the detective's findings.
Rost: I knew you'd say that, North! Now, detective... *winking at you* Let's discuss the rest of the investigation somewhere else...
Rost leads you somewhere the Bangboo can't overhear your conversation.
Rost: Sorry for the trouble! Thanks for playing along with me!
Icon Dialogue Talk I wasn't planning on playing along!
Icon Dialogue Talk I'm not a detective!
Rost: Heh, of course you're not! I know you were just passing by! How can someone as young as you be a great detective on Inter-Knot? I was just trying to save my buddy, that's all.
Rost: It's alright. I'll take it from here. Let's just pretend nothing happened. Oh, and here, take this and buy some snacks or something. Remember, nothing happened.
Rost shoves a handful of Dennies into your hand, gives a half-hearted smile, and runs off. As he leaves, he mutters to himself, "Next, I need to post on Inter-Knot..."
(Obtain Denny Denny ×100)
(Idle)
North: ...
(Talk to North, optional)
North: I'll be here waiting for you, citizen and detective.
Icon Dialogue Talk Don't you think...
Icon Dialogue Talk Your way of speaking is a little weird?
North: I don't have the functionality to detect and change my tone. My preset tone is entirely based on Public Security's standardized configuration, and I'm no different from any other Bangboo at the Lumina Square branch.
(ProtagonistProtagonist): (No, you're definitely different... but let's not get into that. The guy who keeps saying "my best buddy" is a hundred times more suspicious in comparison.)

Check the "Bangboo Operation Logs..." commission on Inter-Knot

There is a good chance that Rost will post a new commission on Inter-Knot. Let's check it out.

Inter-Knot Post Bangboo Operation Logs!
[Commission] Bangboo Operation Logs! Who Knows How?
As the title says! Urgently looking for a Proxy who understands Bangboo to help me repair an operation log that's missing some images... If you have questions, don't ask! I just need someone who can go into the Hollow to investigate on-site! Just read the log with your Bangboo and then fill in the missing parts to match the real scene. Oh, and just a heads up, there might still be remnants of a virus in the log, so make sure you're protected. Any skilled Proxy looking to make good cash, this is your chance. First come, first served! Handsome reward guaranteed!

OP, you don't sound like someone who's asking for help. Does that "handsome reward" give you all this confidence?

Hate to break it to you but I'm afraid it won't be as "handsome" as you'd think. In my years of experience lurking around Inter-Knot, clients who actually offer good pay usually come across much nicer and more polite. Probably cause they really need the help, they offer better pay.

Not only that, but the job isn't easy either. You gotta go into a Hollow AND snap shots with a Bangboo. You could run into Ethereals and end up doing multiple retakes. Not worth it IMHO.

Leave it to me, I'll get that log repaired!

Go to the Hollow and complete the commission

Icon Commission Step Description

Head to the Hollow to complete Rost's commission and fix the fragmented operation logs.
(Upon starting the commission)
Fairy Detective Assistant: "The objective of this commission is to act as a Memory Detective, completing missing parts of the operation log."
(After the event)
(SiblingSibling): Hang on! (‍I can't read the logs. There's too many errors!I can't read the logs. There's too many errors! / There are so many errors I can't read the logs!There are so many errors I can't read the logs!‍)
Fairy: Reason for error: Disorderly access to interface protocol.
(SiblingSibling): Let's fix the interface protocol then!
(Interact with the broken tile)
Fairy: Repair preparations are already underway.
Fairy Detective Assistant: "Detective, I've extracted the interface protocol repair screen. Think of this as a way of preparing your tools before the investigation."
Fairy Detective Assistant: "Please try to manipulate the protocol pipeline and change the connection structure to connect to the final access port."
(After the event)
(SiblingSibling): Anyway, we just need to connect the two ends together, right?
(Interact with the Reset Button, optional)
Reset Rules: Before the operation, Fairy backed up the connection structure of the protocol pipeline. If we encounter a dead end with the repairs, try restoring to the backup point and start over.
But even if we restore our progress, we will only return to the state of disorder we started at...
Activate Device
Restore!
Exit
Not now
(Connect the cables)
Fairy: The interface protocol has been repaired. You can now access the video normally.
(SiblingSibling): Alright! (‍Eradicating errors is a blast!Eradicating errors is a blast! / An interface without errors is the best!An interface without errors is the best!‍)
(Interact with the "Backstream" tile)
Fairy Detective Assistant: "Detective, the video sequence from the operation log is about to be extracted."
Fairy Detective Assistant: "In this recording, two sections of the data are corrupt. They need to be investigated and supplemented."
"▇▇Operation Log": This is an incomplete operation log marked "11:00 - 11:21." By extracting this sequence you can adopt the point of view of the Securityboo. This is key to recovering the lost data.
Let's find out what happened!
Activate Device
Extract! Watch!
Exit
Not just yet

(Extract the data)
North: This is Public Security's disaster prevention guide. Citizens who hear this please answer!
(SiblingSibling): It seems to be looking for citizens who need help.
North: This is Public Security's disaster prevention guide. Citizens who hear this please answer!
North: This is Public Security's disaster prevention guide. Citizens who hear this please...
North: Injured citizen detected! Rescuing immediately!
North: Oh... It's just a fallen mannequin...
North: Public Security's disaster prevention guide. Citizens who hear this please...
North: Suspected cries for help detected! Begin rescue operations immediately!
North: The sound came from here!
North: This board should give way if pushed.
???: Meow~
North: Oh... it's a trapped kitten...
North: Come here.
North: Make sure the kitten can leave safely.
North: Keep working, Public Security disaster prevention guide...
???: Is that a Public Security Bangboo? Hey, I'm over here!
North: Shouting confirmed: A citizen needs help!
(SiblingSibling): (‍Ah, another whole stack of errors!Ah, another whole stack of errors! / Ah, more errors popping up.Ah, more errors popping up.‍)
(SiblingSibling): I have to fix the interface protocol before we can continue.
(Interact with the broken tile)
Fairy: The interface protocol repair screen has been successfully loaded.
Fairy: Please manually perform repair operations.
(Connect the cables)
Fairy: The interface protocol has been repaired. You can now access the video normally.
(Continue playback)
Rost: Yes, I'm saved!
North: Hello, citizen! I'm the Public Security authority responsible for guidance during a disaster...
Rost: Yes yes yes, I know. And I'm a good citizen awaiting guidance!
North: Received. Please follow me then, and I will lead you out of the Hollow.
(SiblingSibling): (‍Hold up. Isn't that Rost!Hold up. Isn't that Rost! / Huh? What are you doing here, Rost...Huh? What are you doing here, Rost...‍)

North: Hm? Something is moving over there...
North: There may be a citizen who needs help!
North: Commencing guidance work immediately!
Rost: Huh? Over there... Wait a second!
(SiblingSibling): (‍The operation log suddenly cut out... Ahhh!! There it is again!The operation log suddenly cut out... Ahhh!! There it is again! / The operation log suddenly cut out...The operation log suddenly cut out...‍)
(SiblingSibling): (‍These error messages are like styrofoam — the more I sweep them, the more appear!These error messages are like styrofoam — the more I sweep them, the more appear! / Sure enough, here they come — those accursed error messages.Sure enough, here they come — those accursed error messages.‍)
(Interact with the broken tile)
Fairy: The interface protocol repair screen has been successfully loaded.
Fairy: Based on evaluation, this will be the final interface protocol that requires fixing.
(Connect the cables)
Fairy: The interface protocol has been repaired. You can now access the final video.
(Continue playback)
Rost: Hang on a sec! Securityboo — no, Officer!
North: I'm not a Public Security Officer. I'm Securityboo. May I ask what is going on?
Rost: You must be seeing things. It's probably just a cat...
North: Cats need saving, too. They are important emotional support for citizens.
Rost: Ughh... I'm not feeling well...
North: What's wrong?
Rost: Ugh... I might... be experiencing corruption symptoms!
Rost: I—I feel awful. Do you have any sedatives?
North: No... During a sudden emergency, evacuation of citizens should take priority!
(As they move, something lurks behind)
Rost: Yes, yes, yes, forget about the cat! Get me outta here!
North: The exit is just up ahead.
Rost: *ahem* Ah yes, I can see it!
North: Please go straight through the exit. I have to go back and continue guiding citizens...
Rost: *ahem*! Here's the thing, I really need a favor from you. *ahem*! ...
(The Sharkboo attacks North)
???: Ehn-na nu! (Shark Tornado Fist!)
Rost: Wow, great punch there — where did this bad boy Bangboo come from?!
(The Sharkboo flees)
Rost: Hey! Officer, are you okay! Hey, wake up!

(Playback ends)
Fairy Detective Assistant: "Detective, the missing parts of the operation log have been completed."
Fairy Detective Assistant: "The current time stamp on the video is 11:11, and the following 10 minutes are completely blank."
(After the event)
(SiblingSibling): It's completely empty? (‍That's pretty weird...That's pretty weird... / That doesn't really make any sense...That doesn't really make any sense...‍)
(SiblingSibling): Anyway, let's exit the playback screen for now.
(Exit playback)
(SiblingSibling): We've completed the commission to finish the video (‍recording!recording! / recording.recording.‍)
(SiblingSibling): Let's grab everything that looks interesting and get out of here.
(Reach the exit)
The Amnesiac Memory Detective: Filled in where possible, but... it feels like it's not that simple.
The Amnesiac Memory Detective: What makes Rost think this video can uncover the truth, especially the last 10 minutes of blank space? Could that be what he's really after...
The Amnesiac Memory Detective: But at least the commission is complete up to here.

Interlude

(Idle)
North: I know you, detective!
(Talk to North in front of Lumina Galleria)
North: I know you. You're the Memory Detective from Inter-Knot.
Icon Dialogue Talk I'm not!
Icon Dialogue Talk I'm just a passerby!
North: Rost told you to say that, right? I get it. I understand the tension between Inter-Knot and Public Security. Don't worry, I won't reveal your true identity as a detective. I'm only here to ask for your help.
Icon Dialogue Talk That's not something a Bangboo would normally say...
Icon Dialogue Talk That's definitely not something a PubSec Bangboo would say...
North: You misunderstand. My preset tone is entirely based on Public Security's standardized configuration, and I'm not different from any other Bangboo at Lumina Square.
North: So, Rost sent me the fixed log, but instead of clearing things up, it just made me more confused.
North: I was attacked at 11:11, and then there's this weird blank in the log for 10 minutes. And at 11:21, there's an entry saying "I'm dead." But who is the murderer, and what is their motive...?
North: I don't trust Rost; his actions in the logs are suspiciously obstructive. But I trust you. You are a skilled detective, and your track record of fixing logs proves it.
(ProtagonistProtagonist): (I hate to admit it, but... I did fix the logs.)
North: I'm curious about what's at the "suspicious location" that Rost stopped me from going to. Please take me to the location in the operation logs for an on-site investigation to examine the crime scene.
Icon Dialogue Talk Okay, I'm curious about the truth, too...
Icon Dialogue Talk Okay. What detective could resist the allure of the truth?
North: Thank you. I'm ready whenever you are. Please lead the way to the scene.
(Idle)
North:
(Talk to North again, optional)
North: By the way, please don't mention this to Rost.

Complete North's commission

Icon Commission Step Description

North wants to investigate the crime scene. Go with it.

Head to Lumina Square and talk to North

Icon Commission Step Description

North is at Lumina Square. Go talk to it.
(Idle)
Rost: So, do you remember now?
North: ...
(Talk to North)
Rost: How about it, North, my best buddy! Do you remember everything now?
North: My data is restored, so yes, I remember everything...
North: We attacked a security Bangboo during an evacuation, and you tried to merge our data cores, but something went wrong. At 11:21, both North and the Bangboo were "dead."
North: But here I am, alive and kicking. So, who am I really...?
Icon Dialogue Talk It doesn't matter who you are.
Icon Dialogue Talk What matters is "what kind of Bangboo you want to be"?
Rost: No, no, no, don't say that, it's still very important! Don't think about such complex life and death issues. There's no such thing as dying for a Bangboo. If you call yourself North, then you're North!
Rost: We did it! Now you can stroll right into Public Security without any trouble! Just make sure to avoid any thorough inspections... Anyway, congratulations on getting your memories back! Let's do something incredible together, just like the good old times, because we're best...
North: We are enemies.
Rost: Huh? ...Wait, hey! This isn't what I had in mind...
North: From a PubSec Bangboo's perspective, I should be arresting you as the attacker. According to North's records, you disregarded "my" pleas and chose to forcibly merge. From any standpoint, you are not my "friend," Rost.
North: The detective is right. While it's important to figure out who I truly am, what's even more important is what I want to do. I want to do the right thing, so my top priority right now is to arrest you!
Rost: Arrest me? Hold on. You can't be serious about arresting your best buddy, right? ...Wait, are you serious? No, North, stay right there! Don't come any closer! ...
The moment North starts to move his short legs, Rost also takes off running, and within a few seconds, both of them have vanished from Lumina Square.
Will they arrest Rost? That's not the most important thing right now. What matters is if North remembers the promise to keep the "Detective" identity a secret... Come back to Lumina Square later and find out.

Post-Commission Dialogue

(Return to North's location at a later time) ‍[verification needed]
(Idle)
North: Hello, detective.
(Talk to North)
North: Hello, detective.
Icon Dialogue Talk Did you catch him?
North: No, I didn't catch him. I got stuck at a red light at a crucial intersection. Sure, I could have reported him to Public Security and got him arrested, but I'm not going back there.
Icon Dialogue Talk Did you go back to Public Security?
North: No. I could have reported Rost to Public Security and got him arrested, but I'm not going back there.
North: From what remains of the operation logs, I realized the attacked "me," the PubSec Bangboo, was named Kami. So, I've decided to start fresh as a new, independent Bangboo with a new name.
North: Kami North.
Icon Dialogue Talk You don't want to be a Public Security Bangboo?
North: I can't go back to Public Security. Despite Rost's lies, he's right about one thing: going back means getting a thorough check-up, being formatted, and re-initialized... And that means losing what remains of "North" for good.
Icon Dialogue Talk Are you going to continue being a Hollow Raider?
North: I'm not sure. I don't want to be a Hollow Raider, but I do know despite Rost's lies, he's right about one thing: going back means getting a thorough check-up, being formatted, and re-initialized... And that means losing what remains of "North" for good.
Icon Dialogue Talk You're starting to sound less and less like a Bangboo.
North: Oh, really? I don't have the functionality to detect and change my tone. My preset tone is entirely based on the... "Kami North" plan.
North: I'll take my time gathering enough information to give meaning to my existence. Until then, I'll be acting under the name Kami North, and I've already found motivation and an inspiring role model.
Icon Dialogue Talk What motivation?
Icon Dialogue Talk Who's your role model?
North: You, detective. You don't pick sides, you just do what you want to. I will take these messy and broken memories with me as I aim to do more good.
North: This isn't over yet, because Rost and I were just subjects for the virus. I will figure who created it and their true intentions.
Icon Dialogue Talk If you need any help...
Icon Dialogue Talk Just post on Inter-Knot and call for the detective!
Icon Dialogue Talk I'll see it.
North: Yeah, I will. As long as we're both on the hunt for the truth, our paths will cross somewhere. After all, what detective could resist the allure of the truth?
(Idle)
Kami North: I'll follow your example.
(Talk to Kami North again)
Kami North: I'll follow your example and become a great detective.
Kami North: Don't worry, Detective. I won't reveal anything about your true identity. From now on, I'll operate just as discreetly as you do.
