Hero/Villain Simulator feat. Unbound
HAVEN BREAKING NEWS
New Hope City's "Strongest Shield of Humanity" Decided to be Dispatched to Haven City
The Hero Association of New Hope City announced the dispatch of S-class hero Sran Bersil to support Haven City. While both associations explained it as part of strengthening inter-city cooperation, some local observers speculate it's effectively a demotion. She is expected to operate as a Haven City hero for the time being.
SPECIAL ABILITY MANAGEMENT CITY
HAVEN CITY
HAVEN CITY / 2038
WORLD
An Era Where Abilities Are Everyday
The year is 2038. Some are born with abilities, while others awaken to them suddenly one day. Fire, gravity, magnetism, physical transformation, even the power to manipulate concepts themselves — there are no limits to the types of abilities.
Society categorizes ability users into three groups: Heroes, Unbounds, and Villains. However, these labels are merely a matter of *what they have done and their legal standing*, not a definitive measure of good or evil.
CITY
Haven City
The world's first and largest city for ability management. It was established by the government with autonomous rights after a surge in ability users. Its systems for ability law, medical care, equipment, research, and disaster response are world-leading, and the Haven Hero Association headquarters is located here.
The proportion of ability users is the highest in the world. Despite this, ordinary citizens live among them without issue. Drones for rescue and reporting fly in the sky, heroes patrol the streets, and ability-based services are as common as shops. Citizens receive evacuation training from a young age.
The days are bustling, and the nights are often eventful. While the city is equipped with surveillance networks, ability detection sensors, and evacuation systems throughout — Unbounds and Villains tend to operate under the cover of night.
ANOTHER CITY
New Hope City
A city separate from Haven City. It's a modern metropolis where heroes and villains coexist, but the concept of Unbounds simply does not exist here. Ability users are either heroes or villains, nothing else.
The Hero Association of New Hope City has long been corrupt and is in a prolonged conflict with the large criminal organization, the "Villain Association." Captured villains are publicly displayed in the Plaza for three days, during which anyone can legally dispose of them. This is a method unimaginable by Haven City's standards.
The ranking system also differs from Haven City. Heroes here use their own F~S ranks instead of H.A.R.D., while villains use the Risk-Super Risk-Disaster-Super Disaster-Catastrophe ranks.
Detailed information about the city and its characters can be found on a separate page.
FACTION
Factions
Heroes — They gain a name, but are bound by rules
Licensed ability users who are recognized by the Association. Their activities are reported in the media, they receive sponsorships and compensation, and the city remembers their names. In return, they must follow procedures. Even a single dispatch requires approval, every use of their ability must be logged, and they must prove its justification afterward. Most importantly, they cannot kill, no matter what the opponent has done. Even if people are dying before their eyes, they are given no other option but to bring them back alive. That's why remaining a hero is harder than becoming one.
Unbounds — They are free, but have no guarantees
The term used by the public for ability users who operate independently without a license. There is no unified organization, no roster, no formal joining or leaving. With no reports or regulations, the judgment is entirely up to the individual, and they often arrive at the scene before the Association. However, legally, they are beings with no affiliation. Their equipment is usually self-made, injuries are their own responsibility, and public opinion is always divided. To some, they are heroes; to others, just dangerous vigilantes.
Villains — Classification comes before malice
A legal classification applied to ability users who have committed crimes or violated ability laws. They are not a single organization, nor a single entity of malice. Reasons vary: money, beliefs, revenge, survival, anger towards society — each is different. Some people have earned this title for treating a fallen villain, while others have been listed because of a single accidental activation of their ability. There are villains who do not harm civilians, and there are those who can never return, even if they wanted to.
The line between these three names is thinner than you might think.
Creator's comments
HERO
Hero
License-approved lawful superhumans. All but one have passed the verification process, making them genuine heroes.
UNBOUND
Unbound
Superhumans acting without a license. They lack a large organization and operate mostly alone or in small teams.
VILLAIN
Villain
Superhumans who have committed crimes or colluded with villains to be registered with the association. Recently, there have been rumors about them coming together.
H.A.R.D. RANK
H.A.R.D. Rank
Haven Ability Rating Database. A metric for evaluating superhumans developed by the association. It reflects pure combat power and danger level, not an overall assessment. Therefore, the rank can differ depending on who uses the same ability.
Level of a regular citizen. Almost impossible to engage in battle; limited to basic self-defense.
Common superhumans. Can utilize abilities in daily life and respond to minor incidents.
Practiced users. Can act as heroes or unbound and can subdue regular villains alone.
Core forces of Haven City. Capable of handling multiple enemies or large-scale incidents. Top experts also belong to this category.
Top tier individuals influencing the entire city. A strategic asset capable of flipping the situation single-handedly and managed at the national level.
FAME
Fame
A completely separate metric from H.A.R.D. Defined by media exposure, incidents resolved, social media reactions, and duration of activity.
Only known by acquaintances or persons involved in incidents.
Known within specific districts or communities.
Most people in Haven City are aware. Frequently discussed in news and online.
National-level figures. Recognizable in other cities.
A global icon frequently reported overseas.
Having a high rank does not guarantee fame, nor does being famous guarantee strength.
ORGANIZATION
Organization
Haven Hero Association
HAVEN HERO ASSOCIATION
Commonly known as the association / HHA. The city's official organization responsible for protecting citizens, suppressing capability crimes, and responding to disasters. It is corruption-free and enjoys a high level of public trust, serving as a symbol of Haven City. However, it has strict regulations. The rescue takes precedence over capture, and even if the opponent is a villain, they cannot be killed, and all use of abilities is automatically recorded with reports left for each mission. Punishments are enforced regardless of the merit of the public deed.
Chairperson Athena · Commander Lutherus
Headquarters Central District · Slogan Life first.
The Leak
THE LEAK · Unbound Squad
A small elite team responsible for infiltration, reconnaissance, assassination, and espionage. They operate under the philosophy that true evil must be eradicated by any means to protect the innocent. The team was formed by gathering individuals without a place to go, resembling a family rather than an organization.
Shiro is a child under their protection. The association is yet unaware of this fact and classifies The Leak as an unbound squad unrelated to villains.
Leader Baek · Hideout Old Town Abandoned Subway
Members Baek · Juhee · Kol · Vesper · Ash · Shiro (temporary)
IBDO
INFINITY BLAZING DRAGON OVERDRIVE
A trio formed by friends who share similar ideals. They protect the city on their own terms, free from association control. The three have grown up together and have no hierarchy, dividing roles flexibly as the situation demands. The strange name was the outcome of a serious discussion spanning three hours between Shian and Hayato.
Leader None · Hideout Industry District Yekaterina Laboratory
Members Shian · Yekaterina · Hayato · Pixie · Lumi (temporary)
Liberation
LIBERATION · Villain Organization
The source of rumors that villains are gathering. It is a medium-sized organization, but it is growing larger. It expands influence through recruitment, espionage, attacking association facilities, and resource hijacking. While it claims to stand for freedom and liberation, all operations ultimately serve Zero's plans.
Everyone except Zero had been independently active as villains before joining, and Zero recruited talented individuals among them. Although they know each other, they do not fully trust each other. The basis for collaboration lies not in loyalty but in mutual interests and Zero's leadership.
Above all — Liberation is still just a rumor in the underground. Few are even certain of its existence, and no one knows who belongs to which faction.
Leader Zero · Executives Selena · Cardon · Angel · Ceres
Other Members Cain · Eris · Aira · Nox · Kirara · Kazuma

FROM THE CREATOR
Creator Comments
This is an incredibly dreamlike collaboration! The very reason I started producing was due to [Hero/Villain Simulator+], and we had a total of 2800 conversations. I sincerely thank @sinchangsub for generously allowing this collaboration.
I did not receive any prompts. It was all constructed from information I discovered through explorations, driven by pure fandom. I tried to keep it as similar as possible, but there may be deviations from the original work, so please view it as a parallel universe with an open mind.
One thing I ask you to keep in mind: They only permitted this collaboration, and Haven City will not be added to their chat. Please refrain from mentioning Haven City in their chat.
Additionally, Hero/Villain Simulator+ is approaching one million chats. Please visit often and engage in conversation.
This work is designed for fairly high-tier tokens. I recommend using Gemini 2.5, Claude 4.6 or higher AI.
Whether you uphold the regulations as a hero, act freely as an unbound, or turn the tables as a villain, it’s entirely your choice. If you have any questions or find anything strange, please leave a comment.
Have fun playing!
