Academy SP 〜An Ex-Mercenary Reincarnated as a Mob in a Gal Game. I Ditched My Bodyguard Job to Enjoy High School Life, but When the Ultra-Rich Heroines Were About to Get Killed, I Stepped In… and Somehow Built a Harem Powerful Enough to Control Japan〜 - Chapter 01

Chapter 01

DADADADADADA!!

—Gunshots rang out without pause, mixed with explosions and sharp cracking noises. The air was thick with the stench of gunpowder and burning metal, enough to sting my throat.

“All units, spread out!! Move it! You’ll get riddled with bullets!!”

—Our officer’s furious shout cut through the chaos.

“Guaaah!!” “Hey, Miller got hit!!” “Not good! His head’s gone!!”

—Screams followed one after another. Bright red blood sprayed through the air.

“Tch… useless idiots…”

I felt irritation rise at my incompetent allies, but I raised my assault rifle and stepped forward anyway.

I wiped out the enemy soldiers in a single sweep.

Because we were short on manpower, a lot of rookies had been sent to the front lines today.

What a pain…

Before something stupid happened, I needed to finish the enemy fast—

“Whaaa—!! Die, all of you!! I’ll blow everything to hell with this!!”

A bad feeling crawled up my spine.

I turned toward the rookie screaming behind me—and sure enough, that idiot had already pulled the safety pin on a grenade.

“You dumbass!! Who the hell told you to do that?!”

I shouted at him… but it was already too late.

“WhaaaAAAAAA—!!”

The rookie threw the grenade—straight at the enemy.

But… the throw was terrible.

The enemy soldiers were hiding inside the forest, and the grenade hit a tree instead.

Then, after bouncing off—

—It came flying right back toward my face.

—Friendly fire.

That was what they called it when you accidentally attacked your own allies.

My life flashed before my eyes.

There was no way left to dodge the grenade as it crept closer in slow motion.

In that split second, I looked back on my life.

Dropped out of middle school.

My teenage years were spent drifting around, working part-time jobs here and there.

At eighteen, I joined the French Foreign Legion.

I went through several deployments, finished my five-year term, and then headed to the Middle East to become a mercenary.

I wanted to test the skills I had trained as a soldier.

And then about ten years passed—living as a mercenary.

Dying at thirty-three years old… huh.

A lot of comrades had died in war.

Some were blown apart by enemy shells.

Some died from illness.

Some were hated by their own unit and got shot in the back of the head.

No matter how good a soldier you were, death came fast.

That was why I had always been prepared for an ending like this.

And honestly, I didn’t regret anything—there was nothing I wished I had done differently back there.

—But… still.

I chose the life of a mercenary, sure, but wasn’t the real reason because I wanted to change myself?

I had been gloomy, awkward, and going nowhere. That was supposed to be why I did it.

Only after dying did I realize it.

I wanted more normal things… like school festivals, club activities… hanging out with friends, getting a girlfriend.

Just an ordinary life—well, maybe leaning a bit more toward the cheerful side.

Maybe that was all I ever really wanted.

So if there was one regret, it was only that.

I wanted to enjoy a fun school life… more.

DOOOOBOOOOOOM!!!!!

The last thing I heard was that cold, lifeless explosion.

My vision went dark.

The smell of gunpowder faded.

The burning heat of the sun disappeared.

And the only thing I understood was that my soul was truly rising up, leaving everything behind.

〇

Beep… beep… beep…

“Huh!?”

I kicked the blanket away and snapped upright in bed.

Only after completing that motion did I realize something important:

I had been sleeping under a blanket, on a bed, and had woken up to an alarm clock.

Years of mercenary life had drilled this into my body. You never knew when the enemy would attack, so the moment you woke up, you got up and prepared to fight.

That habit was burned into my mind.

Which meant I only understood my current situation a moment later.

“Huh? What is this place…? Where am I…?”

I quickly turned my head, checking my surroundings.

The room was about six tatami mats in size.

A desk with a computer, a TV—and a poster of some athlete.

Judging from that, it was a guy’s room.

And somehow… it felt young. No, this was clearly a kid’s room.

“What’s going on…? Was I captured by the enemy?”

No, that made no sense. I was sure I had died in that explosion.

“And besides—”

I glanced at the calendar hanging on the wall.

It was written in Japanese.

Which meant… this was Japan. My homeland?

That was impossible. I had been in the middle of a military operation in the Middle East, and I hadn’t returned to Japan even once.

No—there was something even stranger.

It was the year written on that calendar.

“‘Seitei’… year twelve?”

What the hell kind of era name was that?

What was going on here…?

…………

No, wait.

I had read it as Seitei without hesitation.

Why did I know how to read that?

Something stirred—like a distant memory scratching at the back of my mind.

But then, suddenly, my gaze snapped toward the door.

It was an ordinary hinged door. Nothing special about it.

Yet—

Someone was on the other side.

They were holding their breath, staying perfectly still, just waiting.

—An ambush?

Were they planning to attack the moment I opened the door?

Otherwise, there was no reason to hide like that.

Fine by me. I needed information anyway.

I’d beat them down, squeeze the answers out of them—and if they resisted, I’d erase them.

I deliberately made noise with my footsteps, letting them know I was approaching.

Then, acting like I didn’t suspect a thing, I opened the door.

No one was there.

No—someone was hiding behind the door.

I walked forward calmly and leaned out.

And just as expected—someone lunged at me from behind the door, aiming straight for my back!

I sensed it instantly.

I spun around, grabbed their arm, slammed them face-down, and pinned them to the floor in one smooth motion.

“Heh. You thought you could take me with skills like that? Now talk. Who are you!?”

Wasting time was annoying.

At this rate, breaking one of their arms would—

That was when it happened.

“GYAAAAAAAH!! That hurts, that hurts, that huuurrts!! I surrender! I surrender!! Yuu-kun, stop already!! It’s Papa! Papa!!”

“…Huh? Yuu-kun?”

That ridiculously pathetic scream made the words slip out of my mouth without thinking.

The man I had pinned down had a sagging belly that looked nothing like a soldier’s, a balding head, and crooked glasses sliding down his face.

More than anything—he was just a regular middle-aged guy.

“Mooou, what’s all this noise so early in the morning~?”

At that calm, gentle female voice, I instinctively lifted my head.

Enemy reinforcements!?

…Or so I thought.

Standing there was a housewife-looking woman wearing a flower-patterned apron, ladle in hand as if she had been in the middle of cooking.

“Oh my, Yuu-kun! You shouldn’t twist Papa up like that, you know!? Mama doesn’t remember raising you to be such a violent child! Honestly!”

“H-Huh…?”

I let out a confused sound as the woman puffed up her cheeks and scolded me.

W-What was going on here…?

And what was with this Papa and Mama stuff…?

“M-Mama… please don’t scold Yuu-kun… Papa started it first. After all, Yuu-kun is becoming an ‘Academy SP’ starting today! You never know what kind of enemy might attack from a blind spot, so I thought I’d test him with a surprise attack on his first day… but I never imagined I’d get countered this badly! Yes, Yuu-kun, you’ve really grown strong!”

“Oh, is that what happened~? In that case, Yuu-kun, you’re amazing.”

“Yeah! Our son has grown into a fine young man!”

While listening to the couple calling themselves Papa and Mama—and calling me Yuu-kun—my head was full of confusion.

Still, one word stuck in my ears.

—Academy SP.

Hey… don’t tell me—

“H-Hey… there’s something I want to ask… When you say ‘the first day of the entrance ceremony’… what school am I supposed to be enrolling in, anyway?”

“Ahh, Yuu-kun, are you still half-asleep? The school you’re entering is Yushu Girls’ Academy, you know? Well, it’s a girls’ school, but starting this year they’re allowing boys in too.”

“—!?”

The moment I heard that school’s name, my grip tightened.

“Ow ow ow ow!? Yuu-kun!? H-Hey, Papa’s joints are locked already!! Please, have mercy!!”

A school like that—I had never heard of one in Japan.

No way…

No way…

I immediately released Papa and dashed past Mama.

I ran into the bathroom and looked at my own face in the mirror.

“W-What…!?”

T-This guy was…

That’s right. He existed. I remembered now.

There had been a mob like this in the class!

A completely average nobody with no defining traits at all!!

“I remember now…”

The words slipped out, and pathetically enough, my mouth was trembling.

I had stood on countless battlefields, yet for the first time in a long while, I was shaking from the bottom of my heart.

This wasn’t the Japan I knew.

————————————————————

The time was one of chaos—Japan had lost its former glory, recognized the independence of surrounding nations, and its authority was steadily crumbling.

Amid that turmoil, a shockwave ran through the prestigious girls’ school, Yushu Girls’ Academy.

—The reason was simple.

The daughters of the four most powerful ultra-rich families in Japan were all enrolling at the same time.

The moment this news reached the school administration, alarm bells rang.

Those families had grown obscenely wealthy during Japan’s imperial era, swelling larger and larger even as the economy worsened. To the public, they were nothing but “evil rich people,” and before long, individuals who wanted them dead began to appear.

Protecting young ladies so deeply resented by society…

There was no way ordinary teachers alone could handle that.

—And so, the current headmaster made a bold decision.

For the three years until those elite heiresses graduated, male students would be admitted under a special enrollment system to serve as on-campus bodyguards.

These male students were required not only to have strong academics, proper family backgrounds, and refined character—but above all, real strength, enough to suppress trouble if anything went wrong inside the school.

In other words, to protect the academy’s safety—and the overwhelmingly rich and powerful heiresses—

The school established the Yushu Academy SP (Special Police) Department.

This was the story of the protagonist, Amagaya Shiro, and the elite young ladies of Japan’s most powerful families—

A wild, chaotic, heartwarming academy story filled with laughter, tears… and heart-pounding, sexy moments.

A super over-the-top, feel-good school story!

————————————————————

—Wait, hold on. Somehow I just went along with the flow and narrated the prologue, but…

Isn’t this the world of the gal game Academy SP that I played back in middle school!?

More importantly—

Didn’t I seriously reincarnate into that world!?

And not even as the protagonist—

But as a mob!!

No, seriously—who the hell is this guy!?
