Why You Can't Fire a Nuclear Bomb Lightly
I died.
While playing a strategy game, neighboring countries declared war simultaneously, and because I was so angry, I collapsed with my neck grabbed from behind.
The reason I was attacked was absurd. It was just because I had deployed troops on the border.
The only thing I did besides that was dropping a nuclear bomb on the enemy's capital. About three? No... five?
Anyway, that's not important now, so let's move on.

“Lord! What are you thinking?”
“Nothing special... nothing.”
Currently, I was standing on a cold snowy plain.
“Is this edible?”
“Eat it carefully, it's hot.”
“Wow!”
After ten years since birth, I realized I had been reincarnated as the youngest son of the “Northgard” faction—the weakest in the game.
“Chop! Chop! Roast sweet potatoes!”
“...”
The only saving grace was that with the yandere mode applied, I could see the chubby-cheeked little one chomping on sweet potatoes.
Ta-da-ta-da...
“Wilhelmina, do you like it here?”
I asked quietly to the silver-haired girl in fur clothes in front of the warming bonfire.
“It's cold and I'm hungry, I don't like it!”
“... I see.”
“But!”
She grumbled at first, but then continued, looking up at the night sky.
“The stars are pretty here.”
“...”
That's what she said.
The starlight reflected in her unblinking eyes was beautiful.
“The night sky from the capital's skyscrapers is also pretty.”
“Is it?”
“Shall we go see it together?”
If it was the old me, I would have gone alone without hesitation, but without thinking, I invited Wilhelmina to go with me.
A silver-haired red-eyed girl with soft cheeks and clear eyes.
It was hard to leave the little one who followed me like a chick behind my back.
“Chop!”
“Alright, I'll pack the bags right now.”
“... Eh.”
And with her answer, I immediately prepared to leave.
This place was so cold that people died from it casually, and it was a place of survival of the fittest where barbarians came and took everything.
Even now, taking another route would have had a higher survival rate.
“The knight commander route is good, or the magic route to the magic country would be good too.”
“...”
“Or becoming a priest isn't bad. There are saints, and the church's influence is still strong...”
“Lord!!!”
“Startled.”
But my head, which had been spinning hard, stopped at the girl's cry.
“Should I say goodbye to everyone?”
“... Well.”
“Just the two of us going?”
“Yeah.”
I felt sorry for Wilhelmina, but my decision was firm.
I had been an adult before transmigration, hadn't felt family affection, and knew that if I stayed here, I'd die.
“Will you definitely come back here someday?!”
“Th... at.”
“Promise!”
I reluctantly held Wilhelmina's small finger and made a bitter expression.
I wonder if I can keep this promise.
“Then where are we going now?”
“The academy.”
Don't worry, Wilhelmina.
No matter where we go, I won't let you die meaninglessly like that.

BOOM!!!
“Lord!!! We are done for!”
“I know.”
- KIEEEEEEE!!!
“I'm talking right now! You damn lizard bastards!!!”
How did it come to this.
Our original goal was to graduate from the academy with excellent grades and join the royal guard knights.
...Of course, the moment I opened the textbook in the first class, I closed the book.
“Then why didn't you study normally!”
“I'm a man, so I don't do that!”
“Ah, damn! This bastard who calls me lord...!”
I got full marks in practical but failed in theory, so I was assigned to the worst of the self-deployed regions: the Dragonian Western Front.
Wilhelmina, with high scores in theory first and practical second, was supposed to be assigned to the empress's royal guard knights.
So I was planning to go to the battlefield alone...
- Wilhelmina, do you have to live well there without me?
- Lord, shut your mouth.
- Eh...?
- We'll be together until we die. If you say that again... you know?
- Yeah... sorry...
Wilhelmina, who became a terrifying teton girl, followed with insistence.
Who on earth turned that pure silver-haired girl into a barbarian?
“Lord, Lord.”
“I can't hear~”
Anyway, the Western Front I just arrived at was utter chaos.
Although fewer in number than humans, the Dragonian soldiers with overwhelming power swept the battlefield.
The empire soldiers were just slaughtered by their might.
Puff!!!
“Cough... there are still strong humans...”
“Yeah, hurry up and die.”
Also, I was fighting for my life every day, beheading enemy soldiers in this hellish place.
The Dragonians had tough skin, annoying bastards.
“Is the human who has been rumored lately you?”
“I don't know.”
“No way, according to the report, it's a black-haired black-eyed man like you.”
“...”
But today, unfortunately, a dangerous being appeared.

“The name of the main house is Earth Dragon Earth, the commander of this front.”
She who blocked my way is one of the Four Heavenly Dragons, the empire's strongest martial group.
One of the strong ones who can easily destroy a country, appeared before me now.
KAAANG!!!
“Cough...”
“I've seen a warrior who blocked my one strike for the first time in a long time.”
In the moment I blocked the attack she threw nonchalantly, the shock flowing down my back made my whole arm ache.
I had to buy time until the allies retreated, but a frontal confrontation was clearly a disadvantage for me.
“Young warrior, what is your name.”
But the Dragonian's question, which showed interest in me, gave me a chance to breathe.
“... Frey.”
“I see.”
Soon, Earth, who heard my name, smiled fiercely and gripped her spear.
“Then, young warrior, receive the wrath of the earth!”
“Croooough...”
BOOOOOOM!!!
Soon, the weapons of the two warriors clashed and a loud noise rang out.
.
.
.
Puff.
“... Cough.”
The sword fell powerlessly from my hand.
In the moment the Dragonian's spear pierced my heart, I was enveloped in a sensation as if my whole body was freezing.
“Here it ends.”
Also, looking at me spitting blood, Earth continued with a bitter tone.
I had tried hard, but it was insufficient after all.
- Lord!!
Wilhelmina's scream echoed from far away as I finally lost to Earth.
“Excellent.”
Then, she who had stabbed her spear into my chest raised her voice quietly to me.
“I will not kill my subordinate by appreciating your glory.”
“That... is... really... grateful...”
Swoosh!!!
As the Dragonian with a stern expression nodded and pulled out her spear, red blood spurted from my chest.
- Ah... no!!!
Beyond my fading vision as I fell powerlessly, someone running appeared faintly.
Sorry, Wilhelmina.
Now that I think about it, the cookies I secretly hid a week ago, I ate them all.
But the taste was a bit bland.
- Ah... no.
- Impossible...
- ...Even if I defy death, I won't lose you.
And in my fading consciousness, I closed my eyes with the last sight of a clinging red-eyed gaze.

“Haah?!”
“Lord?! Are you awake?!”
As I screamed out of the nightmare, barely escaping, Wilhelmina sleeping beside me startled and shouted.
“It seems like a huge yandere came out of the dream.”
“... The person who was unconscious for a week suddenly wakes up and says something peaceful.”
“Where am I?”
“This is the rear treatment room.”
I thought I was dead because my heart was pierced without moving, but I seem to have miraculously survived the fight with Earth.
Then, what was my last memory?
Wah!
“Please... please, don't go without saying anything now...”
“Wilhelmina?”
“The knight who lost his lord doesn't know where to go...”
But no matter how dull I am, when she, who was usually blunt, hugged me while sobbing, my heart was uneasy.
“...”
“Let's rest a bit.”
“Yeah...”
For now, I should lock this guy in the treatment room to deal with his mental health too.
“Lord...”
“Yeah, I'm here.”
I stroked her hair and hugged her more firmly as if comforting her.
“Sniff sniff...”
But from earlier, it seemed like she was rubbing her nose on my nape and smelling it strangely.
“Wilhelmina?”
“Shut up and stay still.”
“...”
Because she came much closer than before, I was suffocating with my chest pressed.
Even though I became an adult, the guy who still acts spoiled.
“By the way, a letter came from Northgard.”
“From the main family?”
She calmed down a bit, took out a letter from her bosom and said.
“The eldest son died in battle with barbarians, the second son died of cold...”
“...”
“The lord's last will is to return here.”
I ran away because I didn't want to stay in that territory, but now I have to return there.
In the end, all other routes were blocked.
In this horrific chaos, the only way to survive is one.
“Let's go back home.”
