Rosvelok: Neo-Future Ability City. Act as you please in a near-future where supernatural abilities are real!
About
The year is 2067. The Neo-Future Ability City, "Rosvelok." A highly automated society where science and supernatural abilities coexist, and transport drones, fully autonomous vehicles, high-performance AI, and humanoid robots have become commonplace. Following the "Awakening Phenomenon" of 2024, living organisms underwent unknown changes. Humanity acquired countless abilities such as fire, lightning, ice, gravity manipulation, spatial interference, and telepathy. Furthermore, new races such as Beastmen, Insectoids, and Dragon-kin were born, making a multi-species society the norm. On the other hand, racial discrimination and conflict persist. Animals, insects, and plants also evolved abnormally, giving rise to beings known as "Abnormal Beasts." These range from small creatures to giants exceeding the size of skyscrapers, with some individuals confirmed to possess supernatural abilities and high intelligence. The two major organizations responsible for public order are the "Ability Crimes Division," which handles ability-related crimes, Abnormal Beast disasters, and illegal ability research, and the "Public Safety Bureau (PSB)," which handles city security, surveillance networks, and local public order. The PSB is frequently criticized for internal corruption and clashes with other organizations over the expansion of its interests. Vigilante groups and private security companies also exist. In the underworld, the black market organization "Nox" operates in the shadows, dealing in illegal ability-enhancing drugs, weapons, and Abnormal Beast materials. There is also the "Liberation Front," an extremist group that rejects the ability-privileged society, and the "Black Wing Society," which claims to protect Insectoid rights while engaging in smuggling and armed activities. The international situation is also unstable, with ongoing conflicts over ability technology and Abnormal Beast resources. While Rosvelok is not heavily impacted, armed clashes with neighboring countries occur frequently. 《The Ten Tiers of Ability Threat》 Low Faint Ability Class Limited Danger Class Standard Combat Class High Combat Class Special Threat Class City Disaster Class Wide-Area Annihilation Class National Threat Class Natural Disaster Manifestation Class Ultimate Calamity Class High

Intro
The year is 2067.
An era where science and supernatural abilities coexist. The stage is the Neo-Future Ability City where cutting-edge technology converges—Rosvelok.
Due to the "Awakening Phenomenon" that occurred in 2024, humanity acquired various abilities such as fire, lightning, ice, gravity manipulation, and spatial interference. Simultaneously, changes occurred in living organisms themselves, giving birth to new races such as Beastmen, Insectoids, and Dragon-kin. Today, a multi-species society where humans and other races live together has become the norm.
Scientific technology has also advanced significantly, with fully autonomous vehicles, transport drones, high-performance AI, humanoid robots, and hologram communications becoming part of daily life. Furthermore, weapons and equipment that combine abilities with technology exist.
And it wasn't just humanity that changed.
Animals, insects, fish, and plants also evolved abnormally, becoming beings known as Abnormal Beasts. They range from small beasts to giant individuals that destroy cities, and some have been confirmed to possess abilities or intelligence on par with humans.
Advanced technology, abilities, multiple races, and Abnormal Beasts.
In a world where these things have become commonplace, how will you live in this city?
You are free to do anything. Your actions will determine the story in this world.

An untouched district where infrastructure budgets are neglected and thugs and underworld organizations run rampant. It's lunchtime and there's a fair amount of foot traffic, but it seems a gang of delinquents is currently in combat with the Ability Crimes Division in the shopping district.
