Universal Audio Memory Card

Last updated 2026-06-29

Universal Audio Memory Card is an item that can only be found during exploration of Hollow Zero: Withered Domain, and is one of the Lost Items From the Old Capital.

Despite there being multiple Universal Audio Memory Cards spread across nearly all sets of Lost Items, they all share the same name.

Note

Outside of the Weird Student, who will give the 2 Universal Audio Memory Cards from the Measurement Device set of Lost Items From the Old Capital, the Weird Detective is the only encounter who will offer any other Universal Audio Memory Cards.

The Hollows Bank


#1

Warning! Warning! A Hollow disaster has struck! All Eridu residents are required to...
Run! Does money mean more than your life...
My brother... *crying* ...I want my brother...
Go that way.
T—Thank you...
Tch! You still got time to care about some random kid? Hey, now everyone's gone, I bet the bank is empty. How 'bout we make a quick score?
Besides, once the Hollow reaches here, the cash in the bank will be gone anyway. Why let it go to waste...
Welcome to Eridu Bank. We'll provide your money with the safest...
(Exclaim) I had no idea it was this huge inside! I can't even imagine how much money there must be in here.
The vault's in the basement, let's go.
This has to be the best day I've had in over 20 years. How're we gonna celebrate later?
We gotta to make it outta the Hollow alive first.
Tsk, you're no fun. Get going. When I'm rich, the first thing I'll do is find a doctor to do something with your poker face.
You done with that bag? Something don't feel right. Let's get out—
Look what I've found!
(Sigh of relief) You couldn't hit a target half a meter away. That gun is useless to you.
At least I... Tsk, forget it.
Get the money bag up here fast, we gotta get outta this Hollow before it swallows us.
Hahahaha, I'm gonna be rolling in money!

#2

Have you seen my phone?
You can't call anyone outside the Hollow, so what do you need a phone for?
Never you mind.
Fine, got it. I'd never dare to worry about you.
I don't think I've even asked you yet. Why'd you agree to do this job with me in the first place?
For the money.
True. You'd have to be a [beep—]ing moron not to.
Growing up, I always thought one day I'd be so rich that I have Dennies stuffed in every pocket.
And all the babes would love me, and all my Dennies would be covered in lipstick from all the kisses.
Oh yeah, and I'd buy my dog a bed even bigger than my own, and then feed him sirloin steak every day.
It's a real shame. I have no idea whom we'll be giving all this loot to. What do you think?
Hey, what's wrong?
...Tch... My arm has gone numb. Is that a symptom of corrosion?
Who knows...
You really haven't seen my phone? I feel like one... or two hours ago tops, I had it in my hand.
That old brick? How could you miss that?
Cat got your tongue? I'm talking to you.
...If I end up turning into an Ethereal, you have to put a bullet in my head. Okay?
I said, okay? Don't tell me you can't pull the trigger. You shot at me the very first time we met, remember?
I saw the beating you took while in the hospital. I just wanted to do a good deed, who knew I'd miss?
Then when you have to shoot me, just aim behind me and I'm sure you won't miss.
...Partner, it's not that I don't want to...
My hand seems to have crystallized already... And I'm not sure what it's gonna end up looking like.
I'm thinking, if I turn into an Ethereal first, just put me out of my misery.
Turning into an Ethereal sounds gross. I don't want to dribble and wander around going "Ugh... Argh...!"

The Sanctuary


#1

...I don't think I actually applied to be in this program.
The head of research, who's in charge of new observation point establishment within Hollow Zero, applied for an assistant. You were the only one not currently involved in a project at the moment.
I'm still working on some thesis projects.
As far as I know, your project supervisor is unwilling to review your thesis again. He submitted a retirement application at the young age of 72. So you currently have no projects.
...Uhh... I don't think 72 years old can't be considered young...
Anyway, your new project leader has arrived and will come for you shortly.
I'm reduced to being a mere commodity...
I'm here. Where's my assistant?
Professor Joyce, this is your assistant, uhh—
I know, Dylan, not a single academic thesis published in your three years since graduation. The sole entry in your record is a fainting incident during a Hollow investigation before being carried out by your colleagues. Your only redeeming quality seems to be an above-average Ether aptitude.
I really don't have any remarkable accomplishments or hands-on experience... um... Professor? If you wanted to change—
Professor? Professor... Hehe, me a professor! Don't worry, I'll take full responsibility for you!
That's not what I meant.
Come along, Dylan! Thank that old man for me for assigning me an assistant! I'll thank him myself later!

#2

...Uh... Today's progress on the observation station was normal... Yeah, that's it.
That's not how we do work reports. Normal progress? We can all see that, so it doesn't need to be in your report. You need to include more details. Details!
Miss Joyce, what's your work report? Can you give me an example?
"The delivery of Ether isolation materials arrived today. They brought other supplies, so we had egg rolls for lunch! I hope we get the same tomorrow!"
Like this!
...Isn't this just a normal diary entry?
While out scouting some ruins today, we found some unnatural cracks in the ground. Stepping through produced a spatial displacement phenomenon. We've all read about this in our textbooks, but to actually see it with your own eyes is... mystical?
Dylan, a work diary should be a true record! If you were so scared during the spatial displacement that your legs turned to jelly and you fell down — well, you would have to include that in your entry!
Miss Joyce, please don't randomly add things in when I'm trying to work on my diary.
I'm your teacher, not just any old outsider!
Our observation station reached an all-time high for Ether activity today, but Miss Joyce is not willing to abandon it. My research is just picking up, too, so I hope there won't be any changes for now.
...With the observation station being attacked by several Ethereals today, we've all been evacuated out of Hollow Zero.
My data... Ohhh... I put my heart and soul into it...
Uhgh... (sigh) Our research data was left back at the observation station because we were evacuated in such a hurry. Hopefully we can go back and retrieve it all tomorrow...
Really? Can we really go back and retrieve all the data tomorrow?
I said "hopefully." Please don't get the wrong idea, Miss Joyce!

Blossoming out of Ruins

#1

Run... There's a monster... There's a monster ahead...
A monster? There are only Ethereals in the Hollow. How could there be any monsters?
I don't know, but I've never seen an Ethereal that huge. It doesn't even look like one...
Captain, this is Hollow Zero. Whether it's a monster or an Ethereal in an unknown state, it's not something our current team can handle. We should go.
Take the wounded with you and go. I'll take the rear.
Is everyone here?
Where's Dennis? He was covering us from behind just now.
Dennis? If you can hear me, respond...
I hear you, this is Dennis. Visibility around here is too low. I can't determine my current location.
But there's a Hollow shelter here. I'll hide inside.
Should we come back for you?
I'm no rookie. Send me your coordinates and I'll join you guys when the fog clears up.

#2

Dennis, the fog has dissipated outside and we're waiting for you at the source of the signal we sent you.
Copy that. I'll leave this shelter then. Over.
Stay in contact with us.
I'm not a rookie anymore. Hold your position, I'll be there soon.
What's happening on your end? Hello... Do you copy?
It's beautiful...
What are you talking about? (Playful laugh) What can you see?
A pink flower...
A flower? What's so amazing about a flower?
No, I've never seen such a flower. You have no idea how beautiful it is...
What's that sound on your end? Hello? Hello?
I—I can hear it... It's comforting me. It knows everything I've been through.
It's a monster. That's the sound of that monster from yesterday...
Dennis, it's an illusion... Dennis, where are you?! Give us your location!
No, it's not an illusion. It needs me.
Just a little bit. Just a little. I can feel it wanting me.
Don't go over there! Dennis! Dennis!

Symbiosis


#1

...Today's topic is, "Changes in plant and animal symbiosis while under the influence of a Hollow."
The current biological theory posits that changes occur in the relationship between organisms impacted by these large-scale disasters.
These changes occur to natural competition and the food chain, giving rise to certain new types of symbiosis.
From what we've been able to observe, the ecological chain outside of Hollows has not changed very significantly. Inside the Hollows, however...
Do you mean...
In that case, Ethereals... are also a biological species, yes? Do they also form symbiotic relationships?
A monster like that can't be compared to a natural animal.
If Ethereals could form symbiotic relationships... It would be terrifying.
Don't be ridiculous. Are you expecting Ethereal birds will contribute to cleaning Ethereal rhinos?
We might not have any evidence right now, but within the Hollows, it's the Ethereals who are the dominant life form. We cannot rule out this scenario...

Lucky Ticket


#1

Rock... Are you sure you're okay?
I'm Parker now. Use the right name! Besides, we're here now, so don't tell me you're bailing on us now.
But... This commission's to investigate Hollow Zero, and the other people here all seem to be actual Investigators...
What if people find out about our fake license... Oh!
Listen to me! Think about our life before. We were treated worse than dogs! You don't want to spend the rest of your life homeless in a Hollow, scavenging for scraps of Etheric matter — do you?
No, I don't...
Then shut up! There's more loot down in Hollow Zero than you could possibly imagine. If we can pull off this one heist, then we can—!
Next, please!
Ah, coming! Coming!
Your Investigator license or other official documents please.
Alright! Here you go.
I—Is everything okay?
Mr. Parker, Investigators will be briefed in Conference Room six. Please go straight inside and turn right.
Mr. Parker?
Oh, oh yeah! Yes! That's me, Mr. Parker. Thank you! We'll be off then.
Move it. Quit dawdling.
There's a sucker born every minute...

#2

Sir, this is the ninth case of a Hollow Zero Investigator's identity being forged this week...
Remind everyone, when similar cases crop up, it's okay to turn a blind eye.
There's no need to report such cases to me in the future.
Is it really okay to let so many unofficial Investigators in, especially when they look like Hollow Raiders?
What's the issue? It doesn't matter who they are, so long as we get some valuable information out of it.
(Disdainful laugh) Besides, those Hollow Raiders went in on their own, they've saved us loads on protective gear and supplies.
But the fatality rate...
Their names aren't in the official records, are they?
So let them go. As long as I can get some data out of it, they could be a dog for all I care.

Measurement Device


#1

...Are the numbers still going up?
It's risen 12.8% in the last three hours, sir. If it keeps climbing at this pace, it should reach the Zenless limit in about 36 hours.
Notify all squads: Enter Hollow Zero within the hour. Tell them to destroy as much live Etheric matter as they can.
...But sir, over the past two days we suffered heavy losses. Additional weapons supplies are en route and need another... six hours to arrive.
Can we support a small squad going in with our current stockpile?
Perhaps, Sir. But a single squad could only mildly inhibit the Ether activity growth and would be unlikely to prevent the creation of further Companion Hollows.
But I can't gamble on whether or not there's an explosive rise in Ether activity over the next six hours.
Slowing it down is good enough. We cannot afford the appearance of any new Companion Hollows.
We are currently in an active growth period whereby the volume and velocity of growth inside Hollow Zero cannot be accurately predicted in real-time. The risk of corruption is higher than ever. They'll be—
We're the strongest line of defense New Eridu has. Our soldiers will never allow themselves to be corrupted into Ethereals.
Sir!
Choose an advanced squad... in addition to their regular weaponry, give them each an extra bullet.
Go relay my orders.
...Yes sir.

#2

Hey Zero, go to training room A3 and get me an energy drink, would ya?
Camie... Are you all pulling another prank?
Of course not... We're not the annoying types who'd pick on newcomers.
I'd trust you all more if you didn't tell me carrots could improve my Ether aptitude, take videos of me when I was drunk, play scary sounds behind me while I'm doing the night patrol, suddenly inspecting my dorm...
What? I didn't know about any spot checks? Zero, are you hiding anything...?
Ahem, Camie!
Okay, okay. I'm not messing with you. The A3 training room is way too far. It's only been two days since my injury, you know...
Pretty please...
Fine, I'll go!
Captain, Zero has gone to training room A3. He won't be back for 20 minutes.
I wish we could at least... forget it. Luckily Zero is still a reserve team member; we didn't allocate him any ammo.
I'll join you all after I patch myself up.
Ugh... I'm so sick of it. Why do they love playing pranks so much. I worked hard to join this team 'cause I heard it's a highly decorated squad...
(Sigh)... I just hope there isn't a bucket of water waiting to drop on me as soon as I open the door... I don't want to enter the real world so embarrassingly...
What the...
(Sniffle) Okay, you can come out now. Don't bother hiding to try to spook me. I'm not getting scared today.
Bardie? ...Marlos? ...Derry?
Who are you? What are you looking for?
...Ah... Uh, reporting, Sir! I'm Zero, reserve member of the Wade squad!
A reserve of Wade Squad?
Right!
Go back to the dorms and pack your things. You're being transferred to a new squad tomorrow.
But I've been training as a reserve for Wade Squad. I promised the team I would stay once I turned 18 and passed the assessment...
Wade Squad has gone on a mission. They'll be gone for some time.
But then, I could...
Enough questions, recruit. Pack your bags and report to your new squad tomorrow.

Night of the Hollow Passage


#1

—Darla! This is the first time I've ever seen a real ethereal!!
Stop shaking the bike so much!!! I should've never have believed your nonsense about going into a Hollow—!
It's not like I made who the rumor, and you believed it too— Slow down! I'm gonna fall off!
Any slower and the Ethereal will catch up! The lucky number for this weeks' ticket hasn't come out yet — so I can't let Ethereals get me just yet—
Darla, Darla, did we shake off that Ethereal?
I hope *big gasp* that there really is a crystal door *gasp* in the middle of Hollow Zero offering time travel into the past.
If we really can go back in time, the first thing I bet you will do is hit up the lottery.
I'd never stoop to cheating to win. It's blasphemy against the lottery. I'd lose all my good luck.
Mmm? Really?
What would you do, then? Don't tell me you'd go back to our last math exam and avoid that 59 you got?
Do you really think I'm the kind of girl who'd travel through space and time for such a childish reason?
...Yeah, I do.
Course I wouldn't! Girl, do you actually believe the rumor about this crystal door being a secret time machine?
Cuz I thought you were gonna say "Current Hollow theory suggests this so-called crystal door is merely a massive crystal cluster. The idea of time travel is complete nonsense."
...Why is your impression of me a 70-year-old professor?
I was just painting you as being smart and dependable!
So what will you do once you're back in the past?
You first.
No, you first!
Well I'm the one riding the bike, so you go first.
I'm not good with bikes... And anyway, I was the one who stole the Carrot!
I'm not telling.
Then I'm not telling, either.
You're such a baby.
You are!
Okay then... Once we see the crystal door, we'll count down from three and then we'll both say it.
Deal. —Watch out! It slopes down! Ahhh—!!

Hollow Proposal


#1

L—Let me tell you a secret...
I know you're a Hollow Raider.
D—Does that even count as a secret? Hollow Raiders are everywhere in New Eridu. W—What's special about that... Don't tell me you're an Investigator here to arrest me, hahaha.
And what if I say I am?
You must be kidding, hahaha. Those poor Investigators are worse off than Hollow Raiders. Can they even afford the drinks here?
Even if you really are one, take my advice, give it up. Here's a tip for free. If you've got to the skills, you can live worry-free for the rest of your life.
Alright, what's the tip?
I saw an Ether Crystal in Hollow Zero...
What's so unusual about that?
I've never seen one of such high purity... You could see a faint pink glow from way away.
No wonder the top guns are keeping such a tight grip on Hollow Zero...
There's stuff in there you'd never see in another Hollow.
If I had the skills, I'd totally get a piece of that crystal for myself.
With that piece of the crystal, I could... I could even afford to take over this bar! Then I'd let you drink for free!
It's an amazing thing...
Dude, if you got the skills, you should totally go take a look.
It might be your chance to make a killing!

#2

Come back with me.
What are you doing in Hollow Zero?
You think I'd watch you dig your own grave without doing anything?
I don't intend on dying. I got some intel is all.
You believe that drunk nonsense?
How did you even know...
You sent me such a bizarre message out of nowhere. It didn't take long to figure out where you'd been going.
I talked to some of your old friends. Just, come back with me and we'll act like nothing happened.
It's been like this for years...
You work hard and get things done. You understand people, and you're so smart too...
But I'm just a loser. You're always the one looking out for me.
I... went to look at engagement rings the other day. But I couldn't afford one... even with all my savings.
If it weren't for work, I'd never even consider going to bars like that... But that Hollow Raider was right.
You...
That's it! That must be the Ether Crystal the Hollow Raider mentioned! See it?
Give me a chance. If I pull this off, I'll give you the perfect proposal!
I'll finally be more than just some Investigator that even Hollow Raiders make fun of.
I just... need to get close enough to collect a small piece. Everything will be different after this...!
Have you calmed down yet?
What are you doing? Why did you— handcuffing us, really?
I've looked at engagement rings too. I know they're expensive.
So I've decided to use this as a symbol of our engagement. Be it now or in the future, I'll stand by you.
Wherever you go, I go too.
If you want to get the crystal, I'll go with you. If you decide to leave now, we'll go home together.
So what will it be?
