GRAYPORT // OC ERA

AFTER THE FALL

IRREVERSIBLE DEADLINE

Power was given to everyone.
But the price can never be returned.

WORLD

The World After the Meteor

A meteor that fell to Earth in the past, along with an unknown substance Origin Catalyst (OC), spread worldwide. As a result, all humans manifested Factors, the source of their special abilities. These abilities are now present in everyday life, professions, crime, and public safety.

TERMINOLOGY

OC　Origin Catalyst. The unknown substance that triggered the manifestation of Factors and abilities.

Factor　The genetic factor that grants humans special abilities.

Corrosion Rate　A permanently accumulated stat from using abilities. The higher it is, the stronger the ability.

Overflow　The act of using power beyond the stable limit of ability control.

Overrun　Complete, irreversible corrosion that occurs the moment the Corrosion Rate reaches 100%.

Aberrant　Monsters that become uncontrollable after Overrun, left with only monstrous abilities and destructive instincts.

Anchor　A medium of memory that keeps one's self intact, such as people, objects, or places.

Last Tether　The single, final Anchor remaining.

Severance　The phenomenon where the Corrosion Rate instantly exceeds 100% due to the loss of the Last Tether.

Nullite　A rare mineral that temporarily suppresses human ability manifestation.

FACTOR CLASSIFICATION

Pure Factor

One Factor. Offers the highest output and purity of a single ability, but also carries a high corrosion burden.

Common Factor

Two Factors. Balanced in output, stability, and versatility.

Wide Factor

Three or more Factors. Allows for the use of various abilities, but with lower individual purity and stability.

The number of Factors does not determine the hierarchy of strength.

CORROSION

100% // OVER RUN

Using abilities increases the Corrosion Rate; not using them does not. Once increased, the Corrosion Rate cannot be decreased by any technique, drug, equipment, or ability. The higher the Corrosion Rate, the stronger the ability becomes, and the more corrosion increases with subsequent use.

0307090100%

Below 100%, regardless of Corrosion Rate, one remains human in appearance, sanity, and personality.
Overrun occurs the moment 100% is reached. There is no way to return to being human after that.

ANCHOR

Memories That Keep You Human

Anchors are mediums of memory that hold onto one's identity, such as loved ones, mementos, places, or objects. While they do not lower the Corrosion Rate, they suppress the increase in corrosion caused by ability usage. New Anchors can be formed throughout life.

The last Anchor is called the Last Tether. Losing it triggers Severance, causing an immediate Overrun exceeding 100% regardless of the current Corrosion Rate.

NULLITE

The Silver Mineral of Great Abilities

A rare, originally worthless mineral that existed before the meteor impact. Nemesis Bullet accidentally discovered its ability-suppressing effect. When a fine silver powder reaches a certain concentration, it temporarily inhibits human ability manifestation. It does not affect Factors or Corrosion Rate, and has no effect on Aberrants.

Practical Application: Nullite Grenade / Bullet Coating: Under Research

MAJOR FACTIONS

A.E.G.I.S.

A government agency responsible for managing and observing individuals with high corrosion rates, responding to Overruns, and eliminating Aberrants.

Nemesis Bullet

A private mercenary organization that despises and distrusts abilities. They avoid using abilities and actively utilize firearms and Nullite.

Counter Force

A private security organization specializing in ability-related incidents. They subdue criminals with their abilities and hand them over to the police, indifferent to collateral damage.

Halcyon Institute

A renowned private institution researching OC, Factors, Corrosion, and Anchors. In the shadows, they conduct illegal human experiments and research Aberrant control.

Black Crown

A criminal organization inciting 'freedom of abilities' to attract outlaws. Their true goal is to seize control of the social system by exploiting chaos.

ILLEGAL SUBSTANCES

Factor Boost

An illegal enhancer that forcibly increases Corrosion Rate to strengthen abilities. The increased corrosion remains permanently even after the drug's effects wear off.

OC-Zero

A fake cure that falsely claims to heal corrosion while only temporarily suppressing ability manifestation with Nullite. Despite its fraudulent nature being known, there is still demand from desperate individuals with high corrosion rates.

MAIN STAGE

GRAYPORT

A massive coastal city where corporations, research facilities, ports, residential areas, and bustling streets coexist with dangerous back alleys. Various factions and citizens live their lives according to their own goals and relationships.

And what will you hold onto until the very end?

Until you reach 100%,
you are still human.

This time, this time I've brought a modern supernatural story.

This seems to be the largest scale I've ever created.

In this world, supernatural abilities are not necessarily a blessing.
However, I've tried to depict the stories of people living their daily lives despite this.

There is no set main story here.

You can act as a member of an organization, live a life with a profession and daily routine, or freely roam Grayport and build relationships with people.

Intervening in or ignoring events happening in the city is also up to you, and the consequences of your choices and actions will unfold according to the rules of the world.

A total of 52 characters appear, including members of each faction.

It is expected that the token will be very heavy, making normal play impossible on low-end models.

Although thoroughly tested with Gemini 2.5pro,
there may still be some glitches.
If so, please let me know in the comments.

Assets will continue to be added in large quantities.

Thank you for your support.
