Anononymous asked: Laura will probably fare well in Subnautica

(Rean) “Hey, has anyone seen Laura? I haven’t seen her in the lifeboat or the base.”

(Ainz) “I think she said she was going to go swimming as practice.”

(Rean) “What?! We were told to stick together!”

(Ainz) “I doubt she went far. Besides, it’s Laura we’re talking about. She’s not stupid.”

MEANWHILE

(Laura) 

AGGRESSIVE BUBBLING

unknownsymbol367 asked: Imagine aqua attracting some of the bigger, scarier, dangerous sea beasts all by accident in subnautica.

(Kazuma) “WHY THE HELL DIDN’T YOU TELL US THAT YOU ATTRACT FISH YOU USELESS GODDESS?! NO WONDER THESE FUCKING THINGS HAVE BEEN ALL OVER US!”

(Aqua) “B-Because these are ALIEN fish, Kazuma! How was I supposed to know it applies to aliens!?”

(Megumin) “Uh, I think they’re trying to break through the windows-”

(Darkness) “Ooooh, I wonder how sharp those teeth are-”

(Kazuma) “AQUA’S ABOUT TO FIND OUT FIRST!”

(Aqua) “SCREW YOU KAZUMA, I’M SORRY OKAY!? I-I DON’T KNOW HOW TO MAKE THEM GO AWAY…Wait, that’s it! I CAN CALL IN A REALLY SCARY FISH TO MAKE THEM GO AWAY!”

(Kazuma) “Wha-NO NO NO NO! DON’T YOU-”

“Warning. Leviathan-class lifeform is approaching the base.”

(Minato) “Uh, guys?”

(Minako) “HOLY SHIT!”

(Yu) “I don’t think our swords can go through that.”

(Akira) “Morgana, can you turn into a submarine?”

(Morgana) “YOU IDIOT, I CAN’T BREATHE UNDERWATER!”

- Doomguy looked at his wristblade, then back at the Reaper Leviathan. He repeated this process a few times.

(Yuuri) “Everyone, we need to get our oxygen tanks!”

(Albedo) “Lord Ainz, what do we do?”

(Ainz) “MY GOD THAT’S HUGE-…ahem…WE PREPARE FOR BATTLE!”

(Byleth) “…Why is it when something happens its always you four?”

(Kazuma) “GOD DAMN IT AQUA!”

===

Anonymous asked: I bet the Slayer's Cyclops is named "BFSub" while his seamoth is "SFSub"

(Byleth) “You know Slayer, You seem to use the letters “BF” for a lot of your weapons and vehicles. What does that even stand for?”

- Doomguy grabbed his PDA (Handheld PC) and typed on it for a moment before giving it to Byleth.

(Byleth) “Big fucking-OOOH. So your sub is Big Fucking Sub. Okay, got it…Then the little one must be…Small fucking sub?”

- Doomguy nodded.

(Byleth) “…Well, I’ve heard worse names.”

Anonymous asked: Imagine House Isekai using a submarine.

The Bridge

(Cocytus) “DO ANY OF US ACTUALLY KNOW HOW TO DRIVE THIS…MACHINE?”

(Sara) “Psh, absolutely not. I don’t even know how to use orbal cars.”

(Sharon) “I am afraid my training did not cover controlling submersibles.”

(Cocytus) “…THEN WHY WERE WE PUT IN CHARGE OF DRIVING?”

(Sara) “I mean, all the staff are in charge. Byleth, Megunee, Towa and Angelica too. If we put our heads together, we can think of something.”

(Sharon) “Lady Sara, do you honestly think that we can get the hang of driving before we crash straight into a rock?”

(Sara) “…Probably not.”

Storage/Entrance

(Akira) “It’s pretty impressive that we all got a Cyclops now.”

(Yu) “Yeah, it took a couple days but it’s really cool seeing this in action. Though, should all of us be packed into it? It’s big, but not that big.”

(Minako) “Well, it’s to get familiar. We’re going to get more submarines for each group. Soon us Persona Users will get our very own sub!”

(Minato) “I’m not exactly sure that’s a good idea. I trust tech savvy people like Futaba, Aigis, and Naoto but…people like Ryuji and Junpei worry me.”

(Yu) “I guess we’ll find out.”

(Akira) “…I think I’m having second thoughts about being a part of a Cyclops.”

Engines

(Ainz) …How the hell are we supposed to make this thing work?! I’ve never even seen a submarine before when I was still in the real world! More importantly there was never anything like this in Yg-

(Albedo) “Lord Ainz?”

(Ainz) “Hm? Oh, Albedo. What is it?”

(Albedo) “Demiurge and I have finished looking at the engines, and we have confirmed there will be no trouble in maintaining it.”

(Ainz) “HM?!”

(Demiurge) “It was a bit of trouble at first, but combined with our magic and the PDA’s assistance, we can safely traverse whatever the ocean may throw at the Cyclops!”

(Ainz) “Ah…G-Good work. I can always rely on you two no matter the situation.”

(Demiurge) “T-Thank you Lord Ainz!”

(Albedo) “You are too kind!”

(Ainz) No, really. I’m pretty sure we’d explode if I got something wrong, it’s a miracle that you managed to make heads and tails of this thing…Thank god Kazuma’s group isn’t working the engines…

Loading Bay

(Kazuma) “What, Aqua?”

(Aqua) “A-Are you sure this thing is safe?! I’ve never seen anything like it!”

(Kazuma) “Hell no I’m not sure. None of us here has even been in anything remotely like this. Well except Doomguy, but he’s on bodyguard detail.”

(Aqua) “THEN WHY ARE WE IN THIS DEATH-TRAP?!”

(Kazuma) “You wanna be swimming out there with seaglider where something can eat your sorry ass whole instead of this massive titanium reinforced hull?”

(Aqua) “I…ugh!”

(Yuki) “Hey, hey! Come look at this Megunee!”

(Megumi) “A-Ah! Please don’t run, Yuki!”

(Kurumi) “Even on an alien world, she’s still having fun.”

(Yuuri) “A little TOO much fun. This entire place is terrifying!”

(Miki) “I mean, I find this trip fun as well. I’ve always wondered what it was like to scuba dive.”

(Yuuri) “I’d rather have done so in a coral reef on Earth.”

(Kurumi) “Technically, our first base was in the Shallows where there are coral reefs-”

(Yuuri) “Don’t get technical on me, Kurumi.”

(Miki) “Hah, well I admit it’s scary, but it’s a sense of terror and amazement!”

(Kurumi) “Agreed…Except the Leviathans…I wonder if I can hit them with my shove-”

(Yuuri) “No.”

Anonymous asked: Megumin is gonna have a blast when the aurora explodes.

- Megumin stood on top of the lifeboat, eyeing longingly at the Aurora in the distance.

- Futaba poked her head out the hatch and raised an eyebrow.

(Futaba) “Oh, hey. What are you doing here? I thought you were with Kazuma and the others.”

(Megumin) “I was but now I’m about to watch some fireworks!”

(Futaba) “Fireworks?”

(Megumin) “Yeah, the Aurora’s about to explode!”

(Futaba) “…W-What? I thought our timeframe was 2 hours!”

(Megumin) “Apparently it reached critical state only a few minutes ago-”

(Futaba) “AND YOU JUST NOW TOLD ME?!”

- Futaba’s clothes changed as she got into her Persona and frantically reached for the screen.

(Futaba) “EVERYONE, GET BEHIND COVER OR TO THE LIFEBOAT RIGHT NOW!”

- Everyone stopped what they were doing in the waters and reached for their PDA’s.

[Radio](Byleth) “Huh?”

[Radio](Akira) “What’s wrong?!”

[Radio](Kazuma) “Wait hang on, why?”

Emergency: A quantum detonation has occurred in the Aurora’s drive core.

[Radio](Rean) “Ooooh crap!”

[Radio](Byleth) “SHIT!”

The reactor will reach a super critical state in T- 10,

[Radio](Ainz) “DIVE, DIVE, DIVE!”

[Radio](Megumi) “EVERYONE, IN THE CAVE!-”

[Radio](Yu) “LIFEBOAT, NOW!”

[Radio](Minato) “OVER THERE, GO!”

- Doomguy shrugged and continued looking for resources.

[Radio](Darkness) “K-Kazuma! You’re so rou-”

3-3-…

[Radio](Kazuma) “SHUT THE FUCK UP, DON’T SAY THAT OVER THE RADIO WHERE EVERYONE CAN HEAR-…WHERE’S MEGUMIN?!”

2-2-

(Futaba) “MEGUMIN, GET DOWN HERE NOW!”

(Megumin) “ARE YOU KIDDING, I GOTTA SEE THIS!”

O-

KAFOOOOOOOOOOOOOOOOOOOOOOOOOM!

(Megumin) “Explosions are such a beautiful thing! If only I could be so grossly incandescent…-”

(Futaba) “KEEP YOUR HEADS DOWN, SHOCKWAVE INCOMING!”

(Megumin) “…Shockwa-?”

On Kazuma’s Cyclops: The Wiz…

- Kazuma drove the Cyclops in the open waters, calmly watching his sonar and hearing the hum of the engine.

- Darkness watched the engines alongside Kurumi and Yuuri while Megumin and Yuki were in the vehicle bay.

- Aqua and Miki were in the bridge with Kazuma, watching the status of the ship quietly.

- Until Aqua spoke up.

(Aqua) “OH MY GOD IM SO BOOORED!”

(Miki) “Um, isn’t quiet in a place like this a good thing?”

(Kazuma) “Yeah, having nothing to do in a killer planet means we’re solid! And besides, we said we were going to get copper and stuff, why did you even tag along if you knew nothing would happen?”

(Aqua) “I don’t wanna be left alone at the base!”

(Kazuma) “Then quit bitching.”

(Miki) “That’s a bit harsh, Kazuma.”

(Kazuma) “Oh don’t you start too, Naoki. You’ve been here long enough to know how I am.”

- Miki sighed.

(Miki) “Fair enough. Oh Aqua! Why don’t you read one of my novels?”

(Aqua) “And fall asleep? No thanks. Ugh whatever. At least nothing bad can happen as we’re going back.”

Warning. Entering Ecological Dead Zone.

(Aqua) “HUH?!”

- The waters in front of Kazuma’s bridge went from a clear blue into almost pitch black as he slowly turned to face Aqua.

(Kazuma) “You gotta be fucking kidding me, Aqua.”

(Miki) “M-MULTIPLE TARGETS APPROACHING THE CYCLOPS BRIDGE!”

- Kazuma reached for the mic they installed near the bridge.

(Kazuma) “HEY EVERYONE, STRAP IN, AQUA GOT US INTO SOME DEEP SH…CRAP!”

(Yuki) “Huh? What’s happening?”

(Darkness) “LEVIATHANS?!”

(Kurumi) “Please don’t make that face.”

(Aqua) “HEY WHY IS IT MY FAU-…”

- Aqua’s face suddenly went pale as she looked out the windows.

- Kazuma and Miki turned to the direction Aqua was facing.

(Kazuma) *a noise that can’t decide whether its a swear or gibberish*

(Aqua) “WHY DOES THIS ALWAYS HAPPEN?!”

Anonymous asked: Everybody gangsta until the warpers speak English.

(Sothis) “Hm? Child, we have a new message from the radio.”

(Byleth) “Oh, we do. Heads up everyone, we got a new message coming in. It could be someone responding to our distress signal.”

(Yuuri) “I hope it is…”

(Ainz) “It could be another lifepod, maybe we could find survivors.”

(Minato) “I sorta doubt it, considering all of them have been torn open.”

(Minako) “That’s optimistic…”

(Yu) “But he’s not wrong for thinking it, is he?”

(Aqua) “Whatever it is, I’m sure it’s going to be friendly!-”

(Everyone) “…”

(Akira) “…I don’t think that was human.”

(Sothis) “What was your first hint?!”

(Kazuma) “What. The. F…Hell, was that?”

(Rean) “You just HAD to open your mouth, huh?”

(Aqua) “OH COME ON, NOW WE’RE BEING HUNTED?!”

(Yuuri) “How do we even know if they’re watching us?”

“…”

(Yuuri) “Put more camera drones everywhere, are we in agreement?”

(Everyone) “Yup.”

Day 1 with the Konosuba Gang

(Rise) “Okay, so from what we’re able to scan, this shallow reef seems to be safe to explore, so we’ll split into groups, grab whatever you guys think will be useful!”

(Byleth) “We’ll be going into our respective groups that we came in with. House Reps, you will be the leader of your group.”

- Kazuma and his group nodded, and dived into the water.

- The first area they went into was a somewhat small cave.

(Aqua) “Oooh, this weird tube thing looks pretty!”

(Darkness) “Is it edible?”

- Kazuma put a scanner to it and read the name.

“Acid Mushroom”

(Kazuma) “…Nope.”

- Kazuma continued to swim off as Aqua stared at it.

(Aqua) “Hm…We could use it for something. Right?”

(Darkness) “I will go find the most hostile fish in this area and…hehehe, fight it!”

- With an insane look in her eye, she swam away.

(Kazuma) “Megumin? Find anything in there?”

- Megumin was inside the cave and found a small red-plant like creature.

(Megumin) “I think so?”

- The plant revealed an eye, which made Megumin jump.

(Megumin) “K-Kazuma?!”

- A creature with a giant eye made an unholy noise as it bolted towards Megumin.

HUUUUUUUUUUUURRRRRRRRRRRRRRRRRRR

- A massive explosion could be heard from across the entire shallows as it jolted Aqua and Kazuma into attention.

(Kazuma) “What the hell!? MEGUMIN!”

- Megumin swam out of the cave with her scuba gear clearly dented as a crazy smile took over her.

(Megumin) “THESE CREATURES! THEY KNOW THE ART OF EXPLOSIONS!”

(Kazuma) “You gotta be- KAMIKAZE FISH?! THAT’S GREAT!”

(Aqua) “Hm…”

- Aqua purified the mushroom and looked at it curiously.

(Kazuma) “DO NOT EAT THAT MUSHROOM! Where’s Darkness?!”

(Darkness) “How disappointing.

- Kazuma and the group saw Darkness getting bitten by some shark-like creature.

(Darkness) “These predators will not provide the stimulation I crave.”

- She punched it so hard it flew into the nearby coral tubes, splitting it apart as if it were paper.

(Kazuma) “OH FOR FUCKS SAKE, DON’T GO PICKING FIGHTS WITH THE PREDATORS-”

(Aqua) “K-Kazuma?!”

- The fish began to swarm Aqua, which eventually led to those same shark creatures headed her direction.

(Kazuma) “RETREAT! RETREAT!”

(Aqua) “Psh, it’s just a buncha fish! THEY’RE NO MATCH FOR THIS GODDESS-”

- The predators began to bite Aqua.

(Aqua) “OWOWOWOWOW-”

- Kazuma began swearing loudly and incoherently as he brought up his knife and tried to save Aqua as Megumin and Darkness took care of the exploding fish being drawn to Aqua.

30 minutes later…

(Sharon) “Welcome back, Master Satou.”

(Kazuma) “Ugh…”

- Kazuma flopped onto the lifeboat’s floor, dragging up Megumin, Aqua and Darkness.

- Sharon helped them up and calmly got a towel while Kazuma continued to groan.

(Sharon) “May I ask what you have found?”

- Kazuma reached into his pocket and put them near Sharon’s feet.

- A fish, several teeth from the shark-like fish, some acid mushrooms, and 1 piece of titanium.

(Sharon) “Would you like some tea?”

(Kazuma) “Please?”

New Class VII visit the back of the Aurora

- Altina drove the Seamoth forward while the rest of Class VII tagged along on their seagliders.

- Juna kept looking around left and right until Kurt spoke.

(Juna) “Juna, are you alright?”

(Kurt) “Ugh…No, not really. I don’t like this place is all. It’s so…alien.”

(Ash) “Well yeah, it’s another planet.”

(Juna) “Bah, you know what I mean! We were never trained for this, surviving underwater!”

(Musse) “Neither was the original House Isekai, but they still survived!”

(Altina) “Instructors Rean, Towa, Aigis, and Kazuma seem to have sufficient knowledge of the planet, despite how much time has passed.”

(Juna) “I wonder how the others are doing right now…”

(Kurt) “If I had to guess, like us. Especially the Garreg Mach students, I don’t think they ever anticipated on going on a journey like this.”

(Musse) “Hm…I don’t think the original three houses ever went on this planet, did they?”

(Ash) “Don’t think Rean mentioned it…Er, Altina where are we going?”

- Class VII only now realized where they were. The waters had changed from a blue-green tint to almost brown.

- They couldn’t see very well in front of them.

(Altina) “I was told to search for blueprints. The back of the crash site seemed like the most likely area to find some.”

(Juna) “Wasn’t this the one place all the Instructors told us NOT to go?”

(Ash) “Eh, I’m sure it’s fi-”

GROAAAAAAAAAAAAAAAAAARRRR

- Altina looked to her right and almost stopped breathing when she felt her Seamoth shake violently.

- The Reaper Leviathan grabbed her Seamoth and swam towards the sand cliffs, slamming it down.

(Juna) “OH MY GOD, ALTINA!”

(Kurt) “We have to help her!”

(Ash) “GET THAT BASTARD!”

(Musse) “Arcus, activate!”

(Altina) “I REQUIRE ASSISTANCE-”

…

(Diluc) “…Hm. Class VII still hasn’t returned.”

(Elizabeth) “Oh dear, you’re right. Should we go look for them?”

(Venti) “I’m sure they’re fine. They’d just call us if they were in trouble.”

(Amber) “Still, this place looks pretty dangerous.”

(Helena) “I think we’re underestimating their skills. They’ll be back.”

…

- All of Class VII was on the Reaper Leviathan, stabbing it with tools and weapons while Altina was still in the seamoth, getting crushed.

(Altina) “CLASS VII, I AM PINNED HERE-”

(Juna) “DIE, DIE DIE DIE!-”

(Kurt) “THE SWORDS WON’T GO THROUGH!”

(Ash) “COME ON YA SON OF A BITCH!”

(Musse) “This rifle is going STRAIGHT INTO YOUR EYE-”

…

(Diluc) “…You’re probably right.”

Garreg Mach Students getting used to the ocean

The Garreg Mach students flew out on their seagliders around the safe shallows, being instructed to grab whatever copper they could find.

Sitri followed them since everyone who had been here before was required to stick with a group.

Not to mention she had been here with Byleth before.

(Elizabeth) “Ugh, this is quite unpleasant…”

(Helena) “What, don’t like the ocean?”

(Elizabeth) “Helena, dear. I enjoy the ocean as much as any girl would-”

(Kairos) “Could’ve fooled me.-”

(Elizabeth) “Shut up, Kairos. And I like walking near the beach, and even swimming. But living inside it and fighting nature? No, I do not like it at all.”

(Stefan) “Y-Yeah this is a bit much for swimming.”

(Astrid) “Least we’re all getting our exercise!”

(Kairos) “…Sure.”

(Helena) “It’ll give us experience in case we ever need to swim underwater.”

(Elizabeth) “Where in Fodlan do we possibly need to swim?!”

(Helena) “With all the places the House keeps dragging us into, it might be handy. Hell, it came in handy for Sitri.”

The group stopped swimming and looked at Sitri, who was gliding right behind them.

(Sitri) “Well, I learned it on the fly like you all are currently. But it is helpful that we’ve been to this world before.”

(Stefan) “Just how many have you been to, Lady Sitri?”

(Sitri) “Let’s see…Here, that one world in the far future, the one where we had to hunt ghosts, the one with the talking animals…”

(Helena) “See? She now has skills that’ll be helpful for surviving in another world.”

(Kairos) “How many times has she been underwater for it?”

Sothis appeared behind Sitri, though the students didn’t seem to notice.

(Sothis) “If only they had met Aqua…”

(Sitri) Yeah, I bet they would’ve been terrified of Leviathans…

(Astrid) “Anyways, this place is seriously freaky. The giant sea monsters trying to eat us, and we can’t even use magic here!”

(Helena) “We could always visit the back of the ship like Class VII did.”

(Kairos) “A-ABSOLUTELY NOT, HELENA!”

(Elizabeth) “Do you have a deathwish, dear?!”

(Stefan) “It’s not so much them I’m worried about, as I am about the dark…”

Everyone shuddered.

(Helena) “That’s true, we can’t really see if something’s coming up from behind, and it might just emerge from the-”

(Astrid) “GAAH, SHUT UP SHUT UUUUP! Ugh, I wanna go back home…”

(Elizabeth) “Sitri, ma'am, how did you survive here last time?”

(Sitri) “Well we all took our own Submarines. I think if you ask Kazuma to ride with him on ‘The Wiz’ he’ll let you.”

(Kairos) “Does Professor Kazuma even know how to drive it?”

(Sitri) “Better than most of us did. The only other ones were the old staff.”

(Stefan) “Then what about you?”

(Sitri) “Um…”

(Helena) “Great confidence there, ma'am.”

(Astrid) “C-Come on, you can be a little nicer.”

(Kairos) “Let’s just go back inside, I’m suddenly feeling a bit queasy…”
