Seems like I've been transported to an desert island.

It's a blessing amidst this disaster that Chiyu is with me, but what am I supposed to do now?

"So-kun..."

Chiyu's expression didn't change, but she was probably scared out of her wits.

If a normal high school student suddenly got transported to a place they didn't know, it was only natural that they'd be thrown into a panic.

I myself was just barely managing to keep my head straight; if Chiyu hadn't been there, I might have panicked too.

"It's okay, Chiyu. No matter what happens, I will— "Is this a class teleport?"

If this were a variety show, I'd have dramatically fallen over from the sheer relief that washed over me.

"Yeah, you really are Chiyu."

I couldn't imagine my childhood friend ever falling apart like that.

Just as I thought about it, Chiyu squeezed my hand tightly, the one we'd been holding since earlier.

"I'm lying. I'm scared too. I'm glad So-kun is here."

"...Yeah. Let's try to get through this situation together."

"Yeah. First things first, let's assess the situation."

"Agreed."

Inventory check first. That took no time at all.

Just my uniform and indoor slippers. My pockets were empty, and I had neither a bag nor a smartphone.

Next, a rough survey of the immediate area. I avoided stepping into the forest, given the risk of getting lost.

We'd materialized on a sandy beach, with no other islands visible in sight.

One sun, a blue sky, white clouds.

If there were two suns, we’d know for sure it was another world or planet, but with this setup, it’s impossible to judge.

I didn’t encounter any other humans, but I probably assume our classmates have been transported along with us.

"Besides, there's still a possibility this isn't an desert island, you know."

"It’s good to have hope. But yeah, it’s probably just a desert island."

"Nah, I mean, I think that too, though..."

That had not been a dream; we answered the questions written on the blackboard and were immediately zapped off to this desert island.

Of course, we could have mustered the usual display of panic.

We might have stubbornly clung to the belief that it was a dream, or suspected this was all a TV show taping, or maybe even a kidnapping.

But Sou and Chiyu accepted the situation with a detachment that went beyond merely being apathetic modern kids or being well-versed in isekai manga.

The reason was simple—they could use their abilities.

It had happened just moments before, while exploring the beach.

A pebble had gotten into my indoor slipper, and when I stepped on it at an awkward angle, I injured my foot.

I took off the slipper and sock, only to find blood seeping from the wound.

"Healing Magic"—Basic Cure.

The moment Chiyu spoke those words, light enveloped my injury—and it healed in an instant.

"Huh? Chiyu, was that..."

"Mm. The Mystery Blackboard seems to have given us our abilities properly."

"That's amazing...!"

"I'm a bit embarrassed. What about your side, Sou-kun?"

The entity that had flung us to this island. Chiyu called it the Mystery Blackboard, so I went along with it, but apparently, the bestowal of abilities had been executed without any issues.

It was hard to believe at first, but you couldn't deny what was happening right in front of your eyes.

"Got it! So... how do I use the 'Craft' ability?"

The instant he focused his consciousness on the ability, the method of its use flooded into his mind.

― "Craft Ability"

—— Allows you to convert objects separated from the ground into 'Items'.

—— 'Items' can be stored in your 'Inventory' and placed at any desired location.

—— 'Items' within the 'Inventory' can be used for 'Crafting'.

—— For a list of items that can be 'Crafted', refer to the 'Recipes'.

—— As for how to unlock more 'Recipes', figure it out yourself.

"W-Wait, isn't there some weird terminology mixed in here?"

Just like when a game quickly dumps its settings on you, it was impossible to memorize everything right away.

So, just like with games, I decided to learn by doing.

"I see, I get the gist."

Essentially, you can't extract seawater from the 'Sea' because it's still connected to the land.

This holds true when scooping by hand as well; if it leaks out immediately, it seems the system does not recognize it as having been separated.

I tried using a seashell as a container, and apparently succeeded in "Itemizing" it, causing it to vanish smoothly.

The "Inventory" is essentially what you'd call storage or an item box.

When I focused my will, something like a game interface appeared in my field of vision, displaying "[Small Seashell] x1" and "[Seawater (Trace Amount) x1]".

Even if put in together, they are treated as separate entries once itemized.

Once itemized, it can be retrieved individually as "[Seawater (Trace Amount) x1]" when taking it out.

Recipes seem to be displayed in the form of the crafted item and its required materials.

The currently available recipes include "Lime," "Soap," "Salt," "Spear," "Stone Knife," "Stone Axe," "Wooden Vessel," and "Wooden Cutlery," among others, so there aren't many.

It doesn't seem to be determined solely by what has been itemized.

Lime and Soap were noted as unlocked upon acquiring the seashell. Salt likely corresponds to seawater. As for wood... since I had faced toward the forest, it must have appeared in my view numerous times. Stone was the same.

Regarding the spear, checking the recipe listed wood, stone, and vines as materials.

In other words—

"Do new recipes appear once I personally reach a state where I can itemize them?"

To be more precise, is it a matter of simply discovering them?

Then again, that doesn't seem to be the whole story.

Maybe there are conditions, like having to discover at least half of the ingredients that make up a recipe.

Or perhaps, as in games, recipes get unlocked based on level or creation count, or can only be obtained by clearing specific quests……

No, I shouldn't rely too much on my knowledge of games or isekai comics……

Since no books written by people who've been transferred to desert islands are even for sale, there's nothing in reality to reference.

For now, let me try generating 'Salt'.

— Generated 'Salt (Trace Amount)'.

— Acquired 'Water (Trace Amount)' additionally.

The text appeared in his field of vision.

"Oh...!"

"Did you generate it?"

"Yeah, I did."

So that's convenient.

Drinking water, the most important item when stranded, had become easily obtainable.

But setting that aside.

Specifying his palm as the target, he placed 'Salt (Trace Amount)'.

Several grains of salt landed on his palm.

"...Salt?"

It must be hard to see; Sengyū tilts her head. "Yeah, salt. But it's pretty plain, isn't it?"

"Quite the opposite. If you have the [Craft] ability, it’s incredibly handy."

"I chose this ability precisely because it’s so useful."

In survival games set on desert islands, this is a feature found in almost every title.

Well, within the game mechanics, it's usually treated as the protagonist's craftsmanship skill rather than a specific [Craft] ability.

"For starters, in a situation like this, securing water?"

"That ability seems applicable for that too."

"……No way. Can you separate 'salt' and 'water' from seawater?"

Her voice lacked inflection, but given their long history together, it was clear she was surprised.

"Yeah. You can check the item details, actually. It says 'Safe for drinking.'"

"……It even removes impurities? Truly a remarkable ability."

"Right!"

"Also, what happens to anything other than sodium chloride?"

"Hm?"

"……The so-called 'nigari' (bitter liquid)."

"Aah! Indeed... but there's no display, huh."

There must be some reason behind it.

There were still plenty of mysteries left unsolved.

I'm counting on you!!!!!

It seems like we've been transported to an desert island.

It's a relief to be with Senyuu, but I wonder what we should do now. "Sousuke..."

Senyuu's expression doesn't change, but I'm sure she's probably terrified.

It's natural for a normal high school student to be shaken up when suddenly transported to an unknown place.

I'm trying my best to stay calm, but if Senyuu wasn't here, I might have panicked.

"It's okay, Senyuu. No matter what happens, I'll be there for you." "Is this a class transfer?"

I feel like I'd be making a big fuss if this were on a variety show.

"Yeah, Senyuu is still Senyuu."

I can't even imagine what it would be like if she was panicking.

Then, she suddenly squeezes my hand, which has been clasped since earlier.

"Liar. I'm scared too. I'm glad you're here."

"...Yeah. Let's get through this together."

「Yeah. First, let's get a handle on the situation.」
「Right.」

First, I checked my belongings. This was done in an instant.

I only had my school uniform and indoor shoes. My pockets were empty, and I didn't have a bag or a phone.

Next, I took a quick look around. I didn't venture into the forest, since there was a risk of getting lost.

We had appeared on a beach, and there were no other islands in sight.

There was only one sun, the sky was blue, and the clouds were white.

If there had been two suns, we would definitely be in another world or on another planet, but I couldn't be sure here.

I didn't encounter anyone else, but I think the rest of the class has probably been transported here.

「After all, there's a chance this isn't an desert island.」

「It's good to hope for the best, but I think we're on an desert island.」

「Yeah, I think so too, but...」

This wasn't a dream; we had answered the question written on the blackboard and were sent to this desert island.

Of course, I could put on the usual act of being shocked.

I could stubbornly believe it was a dream, or think it was a TV show recording, or even suspect kidnapping.

But Rikyu and I accepted this situation for a different reason than being modern kids who were jaded or familiar with other-worldly comics.

The reason was simple – we could use our abilities.

This happened just a little while ago, when I was exploring the beach.

A pebble got stuck in my slipper, and when I stepped on it at an awkward angle, I hurt my foot.

When I took off my slipper and socks, there was blood on my foot. "Healing Magic – Basic Healing"

Rikyu said that, and suddenly light enveloped my wound – it healed in an instant.

"Wh-what? Rikyu, what just happened...?"

"Yep. The mystery blackboard seems to have given us our abilities." "That's amazing...!"

"I'm blushing. How about you, So?"

The existence that sent us to this island. Rikyu calls it the mystery blackboard, and I follow her lead, but it seems our abilities were definitely given to us.

It's hard to believe, but there's no point in denying what happened right in front of me.

"Oh, I see! So, how do you use the 'Crafting Ability'?"

The moment I focused my mind on the ability, its usage flooded into my head. -- 'Crafting Ability'

-- It's possible to turn 'objects' detached from the ground into 'items.'

-- 'Items' can be stored in an 'Inventory' and placed in any location.

-- 'Items' in the 'Inventory' can be used for 'crafting.'

-- 'Craftable' items can be referenced in 'recipes.'

-- To increase the number of 'recipes,' you'll have to find them yourself.

"Wow, there are so many terms mixed in."

Just like when a game quickly explains its settings, it's hard to remember everything right away.

So, like a game, I decided to learn by actually trying it. "I see, I get the gist of it."

In other words, you can't take seawater from the 'sea' because it's connected to the land.

This is the same when scooping by hand; if it leaks out immediately, it doesn't seem to be considered separated.

When I tried using a shell as a container, it seems I successfully "Itemized" it, as it vanished.

"Inventory" is like a storage or an item box.

When I concentrate, a game screen-like thing appears in my field of vision, showing "Shell (small) x1" and "Sea water (very small amount) x1."

They may be together when put in, but as items, they are separate.

Once they are itemized, you can take them out as individual items, like "Sea water (very small amount) x1."

The recipes are displayed in the form of the creation and its materials.

Currently, the available recipes are "Lime," "Soap," "Salt," "Spear," "Stone Knife," "Stone Axe," "Wooden Vessel," "Wooden Utensils," and so on, not many.

It's not determined solely by itemized things.

Lime and soap were unlocked when I got the shell. Salt is made from sea water. Wood... I faced the direction of the forest, so it appeared in my field of vision many times. Stone is the same.

For the spear, when I looked at the recipe, the materials were wood, stone, and vines. In other words...

"Will the recipes increase if I can itemize them myself?"

To be more precise, should I find them?

Still, that's not all.

Maybe half of the items required for a recipe need to be found, or there might be other conditions.

Or, in a game, recipes could be unlocked based on level or the number of items made, or only obtainable after completing a specific quest...

Though, relying too much on game or other-worldly comic knowledge isn't good either...

Books written by people who were transferred to a desert island aren't sold, so there's no point in referring to reality.

Let's try generating some 'salt' for now.

--Generated 'Salt (a small amount).'

--Also obtained 'Water (a small amount).' appears in my vision. "Wow...!" "Did it generate?" "Yeah, yeah, it did." That's quite handy.

In a survival situation, obtaining drinking water has become easy. Anyway.

I specify my palm to place the 'Salt (a small amount).'

A few grains of salt land on my palm. "Salt?"

She must not be able to see clearly, since Senyuu is tilting her head. "Yeah, salt. But it's kind of boring."

"It's not. If you can use the 'Crafting Ability,' it's really convenient."

"I chose this ability because I thought it would be convenient."

In survival games on desert islands, this ability is almost always included.

Well, in the game, it's treated as the main character's crafting skills rather than the crafting ability.

"Anyway, in a situation like this, securing water?"

"This ability could be useful for that too."

"…You mean, you can separate 'salt' and 'water' from seawater?"

There's no inflection in her voice, but I can tell she's surprised by her long years of experience with her.

"Yeah. You can see the details of the item, and it says 'drinkable'."

"…It even removes impurities. That's a pretty impressive ability." "What!"

"By the way, what about the other stuff besides sodium chloride?" "Hm?" "…What's commonly known as 'brine'?"

「Ah! Indeed... but there’s no display.」
I wonder if there’s some reason for it. There are still many mysteries.
