——Is there freedom for those with power?

Arkadia City, a world where special abilities exist.

Abilities manifest as the literal embodiment of experiences deeply engraved in a person's heart.

There are powers that save people, and powers that destroy cities. That is why, in this city, "how society treats those with power" has become a major issue.

◆ Arkadia City

A giant metropolis where millions live. With cutting-edge technology and a developed ability culture, heroes stand on a glamorous stage as the idols of the citizens.

However, behind that brilliance lie ability-related crimes, inequality, prejudice, illegal research, and dissatisfaction with the management system.

🏢 Central The heart of the city where government agencies, major corporations, and A.R.C. headquarters are concentrated. Lined with skyscrapers, hero advertisements and large screens color the streets—the public face of Arkadia City.

🎡 Neon Strip A bustling district filled with commercial facilities, entertainment venues, restaurants, and night spots. With many hero events and merchandise shops, it is glamorous, yet information manipulation and illegal transactions often slip through the cracks.

🏘️ Harborside A residential area centered on the lives of citizens. With schools, hospitals, and parks, this is where daily life happens for most. As those with and without abilities live together, prejudices and differences in values sometimes surface.

🏗️ Iron Belt An industrial district where factories, warehouses, and logistics facilities are concentrated. With many dangerous work sites, crimes and accidents utilizing abilities sometimes occur. It shows the face of the labor force supporting the city, distinct from the glamorous city center.

🧱 Old Town An old district left behind by redevelopment. Many residents harbor distrust toward the government and large corporations, and records or rumors regarding past ability incidents remain. A place where the city's "forgotten past" rears its head.

🎭 Underground Not a formal administrative district, but a general term for the subterranean societies existing throughout the city. Informants, smugglers, illegal researchers, and brokers operate in the shadows. However, ordinary people live here too; not everyone is a criminal.

——No matter where you are in this city, the story begins.

◆ A.R.C.

A government-authorized ability response organization. A base for heroes who respond to ability crimes and large-scale disasters to protect the citizens.

Glamorous advertisements, rankings, and media. Behind them, the harsh reality of saving lives continues.

⚔️ VANGUARD | Suppression & Frontline Division

The front line responsible for suppressing and arresting ability criminals and fighting at dangerous sites. High combat capability and instantaneous judgment are required.

🩹 HAVEN | Rescue & Defense Division

Responsible for rescue at disaster sites, evacuation guidance, protection, and preventing the spread of damage. A division that emphasizes bringing someone home safely, not just defeating the enemy.

🔍 SPECTRA | Investigation & Intelligence Analysis Division

Responsible for investigating crime scenes, analyzing traces of abilities, gathering intelligence, and tracking criminal organizations. A division that searches for the facts hidden behind the combat to gather data for operational decisions.

◆ NOCTIS

An underground organization rebelling against the current social system that manages and monitors abilities.

"Should even your own life be managed by someone else?"

While upholding that ideology, they seek to shake the very foundations of the government and A.R.C. system.

However, NOCTIS is not a monolith.

Those who seek freedom. Those who only wish to destroy the system. Those who seek to profit by exploiting the ideology.

They live together in a base converted from a disused underground station somewhere in the city.
