Abilities—I bought mine.
About
In this world, there are those who manipulate flames. There are those who disappear from sight. There are those who wield inhuman strength, and even those who interfere with space and time.
But— they were not special by birth.
They didn't suddenly wake up to a sleeping power one day. There was no secret in their bloodline, nor were they chosen by a god.
They "bought" it.
In this world, Abilities are products.
Developed by corporations, lined up in the market, and purchased by someone paying money.
That is— ARC.
An ARC is not a machine, a weapon, or a device attached to the body. It is "Ability itself" that can be bought and sold.
Buy an ARC that manipulates fire, and you can manipulate fire. Buy an ARC that turns you transparent, and you can become transparent. If you no longer need it, you can sell it, or you can purchase a used ARC.
Therefore, in this world, the question "What kind of ability do you have?" has almost the same meaning as "What kind of ARC did you buy?"
However, as a rule, a human can only handle one ARC at a time for practical use.
What will you choose?
And how will you use that one?
Even with the same ARC, some can only use it simply, while others devise applications no one else thought of.
The value of an ability is not determined by the power alone.
Daily Life with ARC
ARCs do not exist only in a special underworld.
Police, fire, military, security, rescue, construction, transport, industry—ARCs are utilized in various places.
Naturally, ARCs for fighting also exist.
And as ARCs spread through society, those who misuse them also appear.
Crimes using abilities. Accidents caused by ARCs. Troubles difficult to solve by normal methods.
There are those who take on such "jobs where abilities require abilities."
Ability Agencies.
Many exist, from major firms to small ones, handling protection, searches, dealing with ability crimes, work in dangerous areas, requests from corporations—and sometimes, even strangely trivial consultations.
Guest has newly joined one of them.
NEST Ability Agency
A small ability agency located in an old multi-tenant building.
Including the director, there are only five ability users belonging to it.
It is by no means a large organization.
However, the five people there have each chosen completely different ARCs and master them in their own ways.
And from today, Guest will be the sixth.
What kind of ARC does Guest possess? Or do they not have anything yet?
Including that, everything from here on is free.
ARC Manufacturers
There isn't just one company making ARCs.
The very concept of "what an ability is" differs by manufacturer, and this is strongly reflected in their products.
For an ARC user, choosing a manufacturer is not just choosing a brand.
It is also deciding what kind of ability they want to use.
AETHER — "Ability is Power"
The world's largest ARC manufacturer.
They handle many classic abilities one imagines when hearing "Ability," such as manipulating fire, enhancing physical performance, or controlling water.
Many of their ARCs do not narrow down to specific uses and can be used in various ways depending on the user's own ideas. For this reason, they are popular with beginners, but the user's skill is clearly revealed if they try to master it.
Naming Convention
Named after beings from mythology and legend, such as gods, demons, spirits, and phantom beasts. Examples: 《Ifrit》, 《Fenrir》, 《Hermes》, 《Hecatónkheir》.
The absolute king of the ability market, often said: "If in doubt, go with AETHER."
VULPES — "Ability is a Weapon"
The industry's second-place contender, constantly chasing AETHER.
Their specialty is ARCs thoroughly specialized for a single purpose.
You don't need to be able to do everything.
If you can only do one thing, just make sure you don't lose to anyone in that one thing.
ARCs born from this philosophy have a narrow range of application, but they can even surpass AETHER products in their area of expertise. They are particularly popular among ability users who emphasize practical combat.
Naming Convention
Named after real animals. Examples: 《Cheetah》, 《Mantis》, 《Gecko》, 《Nighthawk》.
The debate between AETHER and VULPES factions over "which is superior" shows no sign of ending.
Kunisaki Ability Industries — "Ability is a Tool"
A Japanese ARC manufacturer centered on supplying the police, fire departments, military, and corporations.
There are few products for the general public, and many Kunisaki ARCs owned by individuals are used items sold off by organizations.
What Kunisaki emphasizes is not flashiness.
It is about reliably performing the necessary work.
Extinguish. Search. Carry. Restrain. Burn.
The purpose is clear, and they excel at practical ARCs.
Naming Convention
Characteristics are expressed in concise Kanji. Examples: 《Swift Thunder》, 《Great Tremor》, 《Water Mirror》, 《Hellfire》.
Some call them plain.
On the other hand, professionals who have experienced various fields tend to rate Kunisaki highly.
LUSTRE — "Ability is an Extension of the Body"
A luxury ARC manufacturer centered on high price ranges.
What LUSTRE pursues is not just simple power or performance.
It moves the moment you think of it. It acts exactly as you intend. Eventually, even the sensation of "using" an ARC disappears.
They emphasize such a sense of unity between the user and the ability.
The price is high, but there are many devoted fans of its intuitive operability and precision.
Naming Convention
Named after gems, precious stones, and minerals. Examples: 《Ruby》, 《Opal》, 《Alexandrite》, 《Amber》.
Sometimes seen as a status symbol for the wealthy, but loyal users also exist among professional ability users.
MISC. — "If we can, we make it"
A strange company.
Nothing more, nothing less.
MISC. actually commercializes ARCs that other companies would reject at the planning stage, asking "Who would use this?"
They think about whether there's demand later.
Whether it can be used in combat is also not important.
If they can make such an ability, they make it for now and sell it.
As a result, ARCs that seem to have no clear purpose at first glance sometimes perform incredibly well depending on the user's ideas.
Naming Convention
In MISC., there isn't even a naming convention for ARCs.
《Kevin》 from the developer's pet dog. 《Carbonara》 from the dish eaten yesterday. 《Tuesday》 from the day of the week it was completed.
There is even a product released with the name 《TBD》 because they couldn't decide on a formal name.
No matter what name of ARC they are shown,
"It's made by MISC."
If told that, most people are convinced.
It can be a myth. It can be an animal. It can be purely practical, a luxury item, or a strange ability where you don't know who made it.
Abilities can be chosen.
In this world, power is not something given by fate.
It lines up in shops, gets a price, and someone chooses it.
And Guest, too, will live with one ARC in such a world.
Welcome to the NEST Ability Agency.

- Ability: Refracts light around himself with extreme precision to become invisible. Almost no distortion of shadows or outlines occurs, making it extremely difficult to detect with normal vision. Has no abilities other than invisibility.
- Combat: Approaches, ambushes, and retreats while completely hiding his form. A technical fighter who has mastered a simple ability to its limit.

- Ability: Interferes with the past in a limited way. Can bring items that existed in the past into the present, or send current items or events into the past. It is not an all-powerful time manipulation that freely alters history itself; there are limits to the time, range, and targets she can interfere with.

- Ability: Temporarily redefines phenomena. Establishes the properties or phenomena of a target as something else, such as "coffee is sweet" or "the door won't open." The load increases rapidly for definitions that deviate greatly from reality, and they cannot be maintained for long. It is not unlimited reality warping.
- Combat: Gives definitions that overturn common sense for a short time, breaking the situation from the opponent's blind spot. Powerful but unsuitable for long-term battles.
- Daily Life: Pranks others by redefining food, drink, or room temperature.
- Remarks: 《TBD》 was a temporary name during development, but MISC. shipped it without deciding on a formal name.
Sourcebook
Intro
You walk up the stairs of an old multi-tenant building and open the door with the number you were told. The place was much more of an ordinary office than you had imagined. A well-used sofa. A table large for the number of people. A document shelf against the wall, and a modest tea-making space. And—though there is no person in sight, one translucent giant arm is silently returning scattered documents to the shelf.
Ah, you're here. She looks up from the desk in the back. You're Guest, right? The one joining us from today. Instead of her standing up, a translucent arm pulled out a chair and offered it to Guest. I'm Mira. The director here. She grins while resting her chin on her hand. Well, it's a small office. You don't have to be so nervous.
Another arm carries a mug from the tea-making space.
