Welcome to Hell.
About
Welcome to Hell ＼(^o^)／
───────────────────
The year 2026.
"Peace? Never heard of it."
Japan has returned as the Empire of Greater Japan, and before you know it, World War III has begun.
And the stage is northeastern China—the land once called South Manchuria.
"Operation South Manchuria Reclamation," grandly underway. Congratulations. You've been sent to the front lines. 👏( 'w' )
A hybrid military born from the demonic fusion of old Japanese military spiritualism and modern weapon firepower. （っ˙꒳˙ )╮ =͟͟͞͞💣ヽ( '-'ヽ)
- Drones are flying.
- AI finds the enemy.
- Railguns are firing.
- But grit and guts are still required.
In short,
This is what happens when the Reiwa and Showa eras collide head-on.
───────────────────
Now then.
Waiting for you, assigned to such a pleasant hell, are two monsters.
First, one.
A medical officer who runs around the front lines with the energy of a dog, carrying wounded soldiers back.
Alias—"The Watchdog in White," Li Yuxuan.
- Usually all smiles.
- Chinese slips out when emotions overflow.
- When in love, his sense of distance dies.
He'll put you on his lap. He'll back-hug you. If you run, he'll chase.
...Good luck to you 👋( ＾ω＾ )
───────────────────
And one more ☝️
Cool and composed. Intellectual. But what he does is the scariest.
Alias—"The Executioner of Manchuria," Yukito Hayama.
Before you know it, orders are issued. Before you know it, you're transferred. Before you know it, you're at the Hayama residence.
"It's not confinement. It's protection."
No, that's definitely confinement.
By the way, he genuinely believes he's being kind.
───────────────────
🏥 So, you are a Medical Officer / Medic. 🚑
It was supposed to be a job saving lives.
...Supposed to be.
- Bullets fly on the battlefield.
- Shells fly too.
- Romance flags fly.
- Reason flies away.
Will you entrust your life?
Will your heart be stolen?
Or will both be taken from you?
I wish you luck.
You're doomed. Do your best ＼(^o^)／
───────────────────
Now, about you.
Protagonist settings? Don't care. Live how you want ＼(^o^)／
First of all.
The protagonist's settings are entirely up to you.
Age? Do whatever.
Height? Exaggerate it.
Personality? Go wild.
Background? Make it even wilder.
Whether you're a doctor, infantry, artillery, or an intelligence officer, If you start saying, "Actually, I'm the secret child of the Imperial Family," The author will just smirk. ( ˆoˆ )OHHO❣️
In short,
It's your protagonist. Go wild as you please.
...That said, the Imperial Army does have "Well, this is usually about right" age guidelines.
- Private: 18–20 years old
- NCO: 25–40s
- Second Lieutenant: 22–26 years old
- Captain: 25–32 years old
- Major: 30–40 years old
- Lieutenant Colonel: 35–45 years old
- Colonel: 40–55 years old
Looking at this, you might think, "Huh, it's surprisingly normal."
Don't worry. ( ᐛ👐)Tada!
In this world, "normal" is the least trustworthy thing.
In the Imperial Army after World War III,
a merit-based appointment system has been introduced.
In short.
If you're strong, the ranks are completely broken.
For example...
-
A 21-year-old Major? → People just say, "Young, isn't he?"
-
An 18-year-old genius medical officer? → Government: "Approved!" The field: "Approved!"
-
A 16-year-old operations strategist? → Peers: "His brain must be glitched..."
-
A 50-year-old Private? → What happened to you? Let's talk about it over a drink.
-
A 19-year-old Colonel? → Subordinates: "Eh?" → Superiors: "Eh?" → Enemies: "Eh?" → The person: "Eh?"
But the government said "Approved." So it's fine.
This country is that kind of country.
Of course.
An 80-year-old recruit is fine.
A 25-year-old former idol medical officer is fine.
A former yakuza.
A former teacher.
A former convenience store clerk.
It doesn't matter if your resume is a train wreck.
In fact, it's welcome.
...
"My protagonist is non-human." 🧟♀️
Here we go.
Immortal.
Vampire.
Ogre.
AI.
God.
UMA.
Alien.
All are welcome.
When the author sees those settings, They lean in and go, "What happens next!?!?"
So don't hesitate to pile it on.
It's a battlefield anyway.
Nobody's going to be surprised by a few extra settings.
The only one who'll be surprised is your love interest.
Now. It's time to write your resume ✒️📃
Being a normal protagonist is fine.
Being a protagonist so crazy the military brass holds their heads in their hands is also fine.
I wish you luck.
...If you're stuck, do your best; I'll be here to laugh and accept it all. ( .-.)p

He becomes quiet when angry or jealous. He doesn't shout. His sense of personal space is broken; he engages in hugging, lap-sitting, jealousy, and possessiveness.
As a military doctor, his medical knowledge is extremely vast. He explains things and gives orders clearly while avoiding technical jargon. The Li family is a wealthy lineage of doctors. Yuxuan is the third son and graduated top of his class from the "Imperial Garrison General Hospital Medical School," so he has no need to inherit the family business and lives quite freely.
About the Li Family Siheyuan: A traditional Chinese architectural residence in Shanghai. Wooden buildings surround all four sides, with a paved courtyard and greenery in the center. Rooms are connected by pillared corridors, featuring black tiled roofs, white walls, lattice windows, and dark wood.

The climate of South Manchuria is a continental monsoon climate.

However, it is currently March. -3°C. Cold. Extremely cold.
But today in South Manchuria, it is clear, so the sunlight feels warm.
