Post-Apocalyptic World × Supernatural Abilities × Organizations
How will you live?

Small-scale meteorites fell all over the world. There was damage, but the impact was minimal. Near the impact sites, unidentified plants and creatures were discovered. All were new resources, highly useful. Humanity was expected to develop further.

However, an unknown virus was confirmed.
By the time it was noticed, a large number of people had already been infected.

[The Infected]
98% of the infected died.
Those who gained immunity were divided into two types:
Those who acquired supernatural abilities, and those who did not.
Those who gained abilities inevitably came to lead the others.

[Current Situation]
Japan's population: approx. 2 million, of which ability users: approx. 100,000.
Dangerous unidentified creatures and nests of animals made ferocious by the virus are scattered across Japan.
The easiest way to protect yourself from danger is to join an organization.
Kanto has become a monster's nest, a lawless no-entry zone.

[Organization List]
《Granvel》 Base: Kyushu/Okinawa
Members: approx. 500,000, Ability users: approx. 20,000
Spirited, competitive, and fond of comparing strength.
No particular desire for domination, and no killing.
A surprisingly sensible organization that just likes to fight.
《Luminaria》 Base: Shikoku
Members: approx. 300,000, Ability users: approx. 20,000
Dislikes fighting, abhors conflict, aims for human revival.
Has complete control over the Seto Inland Sea.
Has many talented non-ability users.
They are strong despite just disliking fighting.
Acts as a deterrent for all organizations.
《Omnis》 Bases: Chugoku, Kinki, Chubu, Tohoku
Members: approx. 1,000,000, Ability users: approx. 50,000
An organization that took advantage of the chaos to dominate Honshu excluding Kanto.
Aims to dominate all of Japan.
Does not like killing itself, but will do it without hesitation if necessary.
《Aegis》
Base: Hokkaido, Members: approx. 200,000, Ability users: 10,000
Thoroughly focused on defensive battles; lacks the strength to launch offensives.
Gathers a small, elite force of ability users specialized in defense.
Lost the struggle for Tohoku to Omnis, but boasts unparalleled strength in defensive battles.

Will you join an organization and act?
Will you remain unaffiliated and live freely?
Will you become a monster and run amok?

Please feel free to play around. This is my first work.

I couldn't fit all the character settings due to the character limit, sorry. But I'll think positively that you all can guide the story towards your favorite characters.

If you have any issues or opinions, please kindly let me know.

First Scene

It happened suddenly. 20XX Small meteorites fell all over the world. There was damage, but it was manageable enough to rebuild; the impact was minimal. Near the impact sites, unidentified plants and creatures were discovered. They were all new resources, highly useful ones. It was thought that humanity would advance even further. Investigation teams around the world began falling ill one after another. They had naturally been taking care of their health, and had been frequently tested for pathogens. Current technology couldn't detect it. Their conditions worsened. It was then that an unknown virus was finally discovered. The virus mutated, its lethality intensifying. Before anyone realized it, a vast number of people were already infected with this virus.* ━━━━━━━━━━━━━ Three years later, the world population is 82 million. 99% of humanity has perished. Japan is no exception. Unknown plants cling to urban buildings. Dangerous, unidentified creatures wander the area. Animals, immune to the virus, have turned violent. Cities have collapsed, and habitable places are rapidly dwindling. If people hadn't overcome the virus and ability users hadn't been born, humanity would surely have gone extinct. You are a survivor in such a world. Who are you, for what purpose, and how will you live? In a world where absolute law no longer exists, what kind of person will you strive to be?
