About This Game

Background

On a midnight in your thirties, you wake up surrounded by Lesser Demons closing in for the kill.

Soaked in cold sweat. The mountains around you make no sense; the city walls pulse like a living heart.

Your mind goes blank—

This doesn't look anything like your world.

You are Ren Xia.

A medical doctor. A surgeon.

And the vast continent before you is called Xiaoyao—a land worshipped by countless souls under the rule of a single Divine Emperor.

Day after day, the people of Xiaoyao battle invading evil and the quiet ailments inside themselves.

Your training tells you something impossible:

this world runs on the very same rules as the human body.

—Xiaoyao IS the Divine Emperor's body.

The souls who would die for him are the cells that make him whole.

You are, as of now, the only one in all of Xiaoyao who knows.

You will fight beside the dutiful denizens you meet, and they will come to call you a hero;

You will take up the five great bounties the Emperor has carried for years unsolved;

And as Doctor Hero, on this strange journey, you will peel back the secrets of this world—and seek the way back to your own…

About the Game

*Doctor Hero* is a story-driven RPG built on medical science and clothed in Eastern wuxia.

Through visual-novel storytelling and combat shaped by clinical strategy, you will pick up everyday health knowledge—and serious immunology and physiology—simply by playing.

Across fantastical adventures that span the common cold (acute viral upper respiratory infection), gastritis (chronic atrophic gastritis), cardiac arrhythmia, and pancreatic cancer (pancreatic ductal adenocarcinoma) and beyond,

laugh your way into becoming the kind of expert who can take apart cellular function on demand.

Main Characters

> Beneath the eyes of Doctor Hero, the workings of all things become startlingly clear—

> Even if [Doctor View] sounds like a foreign tongue at first, after playing, the Hero in you will come to understand.

Ren Xia

[Hero View]

To Xiaoyao, you are a stranger of unknown origin, with a gourd of lollipops at your hip.

But you know the truth—you are a doctor of medicine, a surgeon. In this world, can your inner qi and your knowledge work miracles, and carry you back home?

[Doctor View]

You come to suspect, fairly soon, that your role and abilities mirror those of a Natural Killer cell (NK cell).

A sharp blade, the spirit of a wanderer—you will bring profound change to Xiaoyao.

Chun

[Hero View]

The most ordinary of the [Marrow Guard] juniors, a young woman among the first to charge the front lines.

She met Ren Xia by chance during the Lesser Demon incident, and became his trusting, devoted disciple.

[Doctor View]

Innate Immune Cell · Myeloid · Neutrophil

The most abundant of white blood cells. As the immune system's first responders, neutrophils rush to sites of infection and eliminate pathogens through phagocytosis and the release of antimicrobial agents.

Xiao Ba

[Hero View]

A warrior of the Marine Army, risen through layered trials. Cheerful, confident, and gently self-deprecating about his own wits—he hunts traitors and corrupted souls on the strength of intelligence reports and warrants.

He met Ren Xia during the Yanxia Pass crisis—and that meeting stirred up a past he had long tried to bury…

[Doctor View]

Adaptive Immune Cell · Lymphocyte · T Cell · Cytotoxic T Cell (CD8+)

The principal killing force of adaptive immunity. Releases perforin and granzymes to drive infected or transformed cells into apoptosis.

Xiao Si

[Hero View]

The strategist of the Marine Army, also forged through layered trials. Steady and sharp-minded—he supports allies, gathers intelligence, and shapes the rhythm of the field.

He met Ren Xia during the Yanxia Pass crisis—and noticed there was something not quite right about him…

[Doctor View]

Adaptive Immune Cell · Lymphocyte · T Cell · Helper T Cell (CD4+)

Through cytokine release and other signals, the helper T cell coordinates and reinforces the rest of the adaptive immune response.

Zhao

[Hero View]

A Giant Marrow Guard, the lady general who keeps watch deep in the bamboo forest. With a great cauldron in hand, she devours demons and gathers in the remains of fallen comrades alike.

Her bond with Ren Xia, forged during the Lesser Demon turmoil, has set her thinking about Xiaoyao's fate.

[Doctor View]

Innate Immune Cell · Myeloid · Macrophage

A large phagocyte, and a professional antigen-presenting cell (APC)—the bridge between innate and adaptive immunity.

Jian

[Hero View]

An Epithelial Guard, a common citizen standing the front line at Yanxia Pass. No fighter—what he is good at is calling for help and absorbing blows.

Behind that thick-skinned, plain-spoken exterior is a man who, after the Yanxia Pass incident, has come to regard Ren Xia as the one who saved his life…

[Doctor View]

Tissue Cell · Epithelial Cell

Tightly arrayed cells that form the body's physical barrier against external invaders.

Lei

[Hero View]

A messenger—the eyes and ears of the Divine Emperor. Through a secret transmission art passed down within his order, he gathers information across wide regions and reports it home.

The Emperor's surveillance, the Emperor's hearing—his arts are wondrous enough that he can sit motionless and act a thousand miles away.

[Doctor View]

Nervous System · Primary Sensory Neuron

The fundamental unit of the nervous system. Conducts electrical impulses; links sensation to coordination across the entire body.

> And many more companions still wait along the road to be revealed…

> Fight, adventure, and untangle the troubles of Xiaoyao alongside its cells—and rise as the famed Doctor Hero.
