I Was Stranded on a Deserted Island with a Beautiful Classmate - Chapter 31

It was already a huge success just knowing that a ship had passed through this sea area. Someday, they’re sure to notice our presence.

“This gives me hope. Maybe we can go home now.”

“Yeah, seeing a ship means this is probably within Japan’s territorial waters.”

It wasn’t some foreign island. It wasn’t an uncharted island. It didn’t seem to be a parallel world either. This is Japan.

As I felt a sense of relief—huh? I thought I saw a human figure by the sea?

“What’s wrong, Hayasaka?”

“No…Didn’t you see someone?”

“Huh? Where?”

I asked Amane to get up, and I cautiously walked forward. There, I saw a small shadow, tossed by the rough waves.

“…Ugh, aaaaah! Failed again!”

“Whoa, what the!?”

A…float? Something that looked like one came crashing toward me and hit with a thud. I was knocked down on my backside.

“Owww…That hurt!”

“W-wait, what’s going on!?”

Something had landed on me. What just came flying at me…?

“Hayasaka, are you okay!?”

“Y-yeah…Luckily, I’m not hurt. But can you get this thing off me?”

“R-right. Wait, this is…”

Amane pulled the mysterious object off me. Upon closer inspection, it was indeed a float…with a young girl on top of it.

“Uh…is she an elementary school student?”

“No, I’m not! I’m a highschool student! A highschool student, okay!?”

Seriously? She doesn’t look like a highschool student at all.

And on top of that, she’s wearing a school swimsuit. Her name tag says “Momose.” Her pink hair, though probably natural, is quite flashy.

“Are you a student from our school?”

“That’s right, Hayasaka! I’m in your class! Don’t you remember?”

“Wait, really!?”

“Don’t look so surprised!”

The fact that a girl from my class actually remembered my name was enough to move me. I thought I was treated like I was invisible, but maybe I was wrong.

“How did you recognize me?”

“Come on, it’s normal to at least remember the names of people in your own class. But still, I didn’t expect to find you with Ai-chan.”

No, it’s not normal to memorize everyone’s name. That’s a hassle. Maybe Momose is just the type to remember everyone. She’s really meticulous. While I was thinking that, Amane started asking Momose about the situation.

“So, it’s Momose-chan.”

“Hey, Mana-chan. I’m glad you’re okay.”

It seems like the two of them are on good terms.

“Yeah, I’ve been with Hayasaka and some other students from different classes.”

“Is that so? I’ve been living in survival mode all by myself.”

“Wait, all alone!?”

“Yeah, on the day of that typhoon…I came across some important information.”

“Information?”

“I overheard the grade head talking. Tachikawa-sensei is apparently searching for Captain Kidd’s treasure. He’s plotting with someone named Kurashima to sink the ship in a major incident.”

Kurashima…?

That guy was secretly meeting with the grade head?

Wait, does that mean this was all planned from the start…? And Captain Kidd’s treasure—if that’s true, then this is “Treasure Island.”

“Is that true, Momose?”

“I’ve got the recording on my phone.”

It seems like Momose’s phone survived. She played the recording for us.

‘…Kurashima, I don’t care about the students’ lives. What I want is enormous wealth…the treasure…’

This gravelly voice—it’s definitely the grade head’s! This is real!

‘I never imagined Tachikawa-sensei would confide something like this in me.’

‘There’s no one else I can rely on. I know you’re the son of a boss of a certain organization. That’s why I let you enroll at this school.’

‘So, you want me to sink the ship?’

‘Exactly. Everything is already prepared.’

‘Of course. The explosives are already planted on the ship. I can sink it whenever I want. And luckily, there’s a typhoon approaching today. The students will surely scatter.’

‘That’s all within the plan. I’ll give you the girls you like. Do whatever you want with them. I’m heading to “Treasure Island” with John Smith, the foreigner I hired for this plan. That’s where Captain Kidd’s treasure lies.’

‘Is there really treasure there? Involving the students like this…you’re a monster.’

‘I need to be declared dead for this plan to succeed. That’s why I even made a fake corpse. But if I’m the only body found, people will be suspicious. So, I’ll mix in the students’ bodies as well.

Here’s the scenario: the ship capsizes due to damage from the typhoon, multiple students are thrown into the sea, either drowning or going missing…Some may be lucky enough to drift ashore, but surviving in these isolated waters will be next to impossible. Most will perish, and the incident will be treated as an unfortunate accident.

Kurashima, you can have the girls you desire. Build your own utopia on some island. I will take the treasure and escape abroad.’

‘I understand, Sensei. I’ll be happy with ten cute girls like Amane. It’s time to establish my harem empire! …Heh, hahahaha…!’

At that moment, the recording ended.

Both Amane and I were speechless at the shocking revelation.

We stood there in silence for about three minutes.

“What the hell is this!?”

“Kurashima and the grade head…So that’s why the ship sank…It’s all their fault!”

Both Amane and I were furious.

To think not only Kurashima, but also the grade head Tachikawa had planned all this…They didn’t care about the students’ lives!

They sank the ship for their own selfish gain. It’s too cruel. This kind of evil can never be forgiven.

“At first, I thought it was some kind of joke or prank. But when the ship really sank, I was convinced. Those two are devils…I’m sorry, if I had warned everyone sooner, this might not have happened…”

“No, anyone would’ve had a hard time believing it. But this means there’s a chance Tachikawa is still on this island.”

“I think this island might be ‘Treasure Island.’ I’m not sure, but…”

We defeated Kurashima, but the real enemy is the grade head.

Could those bubbles we saw in the lake not have been from Kurashima…? No way, was someone diving in a place like that?

But if they were searching for treasure, it makes sense.

“We need to tell everyone back at the base.”

“Base?”

“Yeah, Amane and I have been sleeping in a cave. You should come with us, Momose.”

“Sure, I’ve got nowhere else to go, so I’ll tag along.”

“By the way, where have you been staying, Momose?”

“I’ve been sleeping in a hammock I set up by weaving a net in the trees nearby.”

What an impressive skill. Apparently, Momose is good at climbing trees and has been living off the fruit that grows there.

She also seems to have some useful items.

As we walked, I explained to Momose everything that had happened up to this point.

After walking through the forest, we finally reached the base.

Kitakami and Chitose were sitting in front of the campfire.

“Good morning, Kitakami.”

“Good morning. Where have you been…wait, who’s that?”

“Oh, this pink-haired girl is Momose from my class. We found her on the beach.”

“You found her!?”

“It’s a long story…but for now, there’s something important we need to talk about. Once Yaegashi and the others gather, I’ll explain everything.”

An hour passed while we waited for everyone to gather. Ooi and the others walked over from the original base. That made thirteen of us, including me. They’re all girls…Was this part of Kurashima’s plan?

But I’m the one at the center now.

Sorry, Kurashima.

Your plan has been foiled.

But that’s no longer the most important thing.

I played Momose’s recording for everyone to hear…
