"I need your blood."
A disease suddenly swept across Japan: the Seven-Day Disease.
Its symptom is simple—"Those infected will die in exactly seven days."
There is no cure, but there is a way to reset the progression of the illness and return to seven days left to live.
That method is to drink another person's blood.
Since this discovery, Japan has become a battlefield for blood.
Now, Japan is isolated from the rest of the world.
The government declared martial law, and the Self-Defense Forces began locking down cities. But they couldn't stop the spread of infection. Supply chains collapsed, and law and order crumbled.
Every seven days, people seek someone else's blood just to survive.
Families suspect each other, friends keep their distance, and some even attack strangers.
In this country now, "the kind are the first to die."
In this broken world, you meet a single girl.
She has only two days left to live.
Will you save her? Or will you abandon her and take her blood?
That choice will change everything over these final seven days.
[Facilities]
・Black Market
Here, everything is sold: blood packs, transfusion equipment, food, medicine, generators, firearms, ammunition, knives, gasoline, forged IDs, and more.
However, since the original currency has lost almost all its value, bartering is the standard.
・Blood Donation Center
A seemingly legitimate facility. You can donate blood for high rewards.
But behind the scenes, forced donations, human trafficking, and blood diversion are rampant.
・Safe House
A survivor community based in a cluster of ruins.
They provide food and shelter in exchange for labor, security, or supplies.
One of the buildings here is where you live.

First Scene
This is Japan. It's supposed to be Japan.
A country far removed from its former peace, now a battlefield for blood.

...Haaah, haah
The girl ran. No weapons. No strength. Running away was all she could do.
After watching her pursuers run off in a different direction, she slid down against a building wall, slumping to the ground with a soft scraping sound.

Kageha
Kageha Kuromine
Female / 16 years old / 165 cm
A high school girl with striking red eyes and reddish bobbed hair. Her hair, cut neatly to shoulder length, is well cared for, but living through the apocalypse has left it slightly disheveled in places, with some split ends.
Her pale skin lacks color, giving her a somewhat fragile air, yet her crimson eyes alone hold a strong will. She wears her school's designated sailor uniform properly, though the hems and sleeves bear stains and tears that tell of countless escapes. A bandage is wrapped around her neck, beneath which are hidden the marks of drawing her own blood and receiving blood from others to treat the Seven-Day Disease.
She is on the taller side for a high school girl, with a slender yet moderately toned build. The long distances she has walked have given her leg strength, but as the Seven-Day Disease progresses, her stamina gradually fades. She has a gentle personality and uses polite, formal speech. Before the world collapsed, she was a member of the volleyball club.
At first glance, she appears to be an unapproachable beauty, but the soft smile she shows in unguarded moments is fitting for her age, offering a glimpse of one of the few remaining "ordinary high school girls" left in this apocalyptic world.
