I Was Stranded on a Deserted Island with a Beautiful Classmate

Her name seems to be ‘Kitakami Kizuna.’

She’s a girl from the same class, and despite her gal-like appearance, she was quite polite. Although, she did point a knife at me.

“Um… Kitakami, right? I’m glad to meet another human.”

“You came to rescue us, right? I was alone too, so I’m relieved.”

“…Unfortunately, we’re also in a distress situation.”

“What…?”

Still straddling me, Kitakami dropped her shoulders.

How long is this going to continue?

It’s not that heavy, but… Amane is looking at me with a pout.

“Let’s just get along for now. The more people, the higher the survival rate.”

Upon my suggestion, Kitakami sheathed her knife.

She finally got up—at that moment, I saw pink.

…While I was pondering this, Amane nearly stomped on my face, so I avoided it. And now, I see it again.

“Tsk, missed.”

“What are you doing, Amane? Puffing up like that.”

“Shut up. Do you like gals, Hayasaka-kun?”

“I don’t dislike them.”

“I see… Maybe I should dye my hair.”

“Amane, why are you mumbling?”

“N-nothing!”

She blushed and turned her face away.

What’s up with her…?

Did I say something?

“By the way, Kitakami, why are you carrying a knife?”

“Good question, Hayasaka-kun. My hobby is survival games.”

“Oh, so you have an air gun?”

“Yes, and I also have a knife.”

That’s an unexpected hobby.

This gal-like Kitakami, huh.

Seems kind of cool.

“This foldable knife is small enough that the teachers won’t notice if I keep it.”

Indeed, Kitakami’s knife is quite small. It’s not a survival knife.

It’s a multi-tool with pliers, a screwdriver, a saw, and a file, typically used in outdoor activities.

Must be a Leatherman.

She knows her stuff.

“A knife is versatile. Kitakami, if you don’t mind, could you help with cooking?”

“Sure, but please spare me from bugs.”

Bugs are a valuable protein source, though.

Still, I don’t like eating weird things. It’s something I’d do only if necessary.

“Got it. I’ll avoid them as much as possible. By the way, this cave…”

“It seems safe here. If we had a fire, it would be even safer.”

I quickly took out the fire starter.

Kitakami was surprised.

“Wow, a fire starter! Hayasaka-kun, you have something good.”

“With Kitakami and me working together, we’re almost unbeatable.”

For survival, having a knife and a fire starter is usually enough. That’s been proven by famous adventurers.

Like Bear Grylls and Ed Stafford.

I started to see a bit of hope—just then, Amane shouted.

“Wait a minute!”

“What’s wrong, Amane?”

“It’s unfair for just the two of you. I have items too.”

“Come to think of it, I thought you were empty-handed… Do you have something other than your phone and wallet?”

“Ah, I have something! Look, an aluminum sheet!”

“Wow!!”

Both Kitakami and I couldn’t help but exclaim.

It’s a pocket-sized aluminum sheet. When unfolded, it’s about the size of a blanket and is quite warm. It also has insulation effects, making it quite useful.

Wow, you had such a good item.

“Amane, that…”

“Yes. Before the ship sank, the teacher gave it to us for emergencies.”

“I see. I was on the deck, so I didn’t notice.”

I wonder how the teacher and other students are doing now. For now, it’s just me, Amane, and Kitakami on this uninhabited island… I hope they’re okay.

After checking the items, I took another look at the cave.

It seems to go quite deep. It’s dangerous to go too far in, so I decided to make the area about five meters from the entrance our ‘base.’

It’s dim, but visibility isn’t too bad.

“So, what should we do now?”

Kitakami looked at me with her eyes, and I felt a bit confused. I get nervous just talking to Amane, and now it’s Kitakami. I guess I have to get used to it.

“I’m thirsty and want to drink water. Kitakami, do you have any ideas?”

“Water, huh…? I haven’t had much to drink either. Hayasaka-kun, can’t you do something?”

Hmm, even if she says that.

I’m not a cheat character reborn in another world. I can’t use magic, so I rely on survival knowledge.

At times like this—

“…!”

Suddenly, Amane was wiping her face.

“Amane, is your eye hurting?”

“No. There are water droplets falling from the ceiling…”

“That’s it!! Amane, thanks to you, we might solve the water problem!!”

“Huh? What do you mean?”

You didn’t realize it!?

I explained to everyone.

“Drink the water droplets. Inside the cave, it’s relatively clean and can moisten your throat a bit.”

“Oh, I see! Hayasaka-kun, you’re a genius!”

“I didn’t notice that… I’ve been in the cave for half a day.”

They quickly opened their mouths towards the droplets.

They savored the drops falling slowly.

…Delicious.

Even though it’s just a drop of water, it tastes so good. I’d like to drink more, but this is all we have for now.

Amane and Kitakami were also enjoying the droplets.

“…Phew, that was refreshing.”

Though it wasn’t satisfying, it helped a lot. For now, it’s enough.

“Glad to drink water. It’s thanks to you, Hayasaka-kun.”

“No, it’s thanks to Amane’s face catching the droplets. We’ve secured a small amount of water. If we had a container, we might be able to collect more while we sleep.”

In times like these, we should head to the beach.

There’s almost always a plastic bottle among the trash coming from Honshu or overseas. And there are many useful containers too.

Recently, plastic waste issues are frequently pointed out, but in times of distress like this, they become invaluable items.

“You two should look for containers and food… Huh?”

It seems they were staring at each other or rather glaring at each other. When did they get into such a heated argument?

“Kitakami, I’ll go out with Hayasaka-kun.”

“I’m the one with the knife, so I’m more useful. Right, Hayasaka-kun?”

What happened in such a short time!?

“Wait, wait, calm down, both of you. We should work together.”

But they kept glaring at each other.

This isn’t good; fighting here is pointless. It only wastes energy.

It looks like I have to calm them down.
