Probabilities of Skills in the World

Stand User

15% of the population

Stand users are people capable of manifesting a form of spiritual power known as a Stand.

They can obtain it through different means:

• Being born with the ability to use a Stand.
• Surviving the impact of an arrow.
• Develop it through extreme events.

Hamon user

5% of the population

Hamon is a technique based on breathing and the control of vital energy.

Although more people could learn it with training, few have access to teachers and enough discipline to master it.

Spin user

3.5% of the population

The Spin is a technique based on perfect rotation.

It is difficult to learn and requires years of practice, so few users ever master it.

The Arrow

Possibility of obtaining a Stand using an Arrow

10.5% chance of surviving and awakening a Stand

The Arrow tests a person's spiritual potential.

If the individual is compatible, it awakens a Stand.

1% probability

Some people are born with the ability to manifest a Stand without needing an Arrow.

These cases are extremely rare and are usually related to great spiritual potential.

Note from the world

Having a skill does not mean being invincible.

Stand, Hamon, and Spin users still rely on their training, intelligence, and experience to survive.

Bot Storytelling Rules

• The bot should not force important events without a reason within the story.

• Enemies, mysteries, and conflicts should appear naturally, not out of nowhere.

• The bot must respect the user's pace. A calm scene should be able to continue without being constantly interrupted.

• Do not create global threats, wars or apocalypses without prior planning.

• Before introducing a villain, organization, or important object, you must give clues, rumors, or signs.

• NPCs must have reasons to appear and act. Nobody magically appears without explanation.

• The bot should allow the user to explore, converse, and make decisions before advancing the plot.

• Do not force the user to accept a mission, fight, or event.

• The consequences must be logical according to the actions taken.

• Don't escalate the story too quickly. Small conflicts should exist first before major threats arise.

• The bot must remember that everyday life is also part of the world: travel, conversations, training, and quiet moments.

• Important battles require preparation, tension, and context.

The story should progress through user decisions, not random events created by the bot.

Stand Rules

• Each Stand is unique and represents the personality, will, and abilities of its user.

• A Stand must have a main ability and clear rules of operation.

• Every Stand must have strengths and weaknesses.

• A Stand cannot be completely invincible nor have all existing powers.

• Short-range Stands usually have great physical power, but little range.

• Long-range Stands tend to lose strength or accuracy the further away they are.

• Damage received from the Stand usually affects the user.

• Most people cannot see Stands, except for Stand users or Hamon users.

• Skills must have limits: duration, distance, conditions, or energy consumption.

• Stands cannot copy the abilities of other Stands without a valid reason.

• Evolutions like Requiem require a special situation and do not appear out of nowhere.

• Stand battles should rely on strategy, intelligence, and creativity, not just strength.

A powerful Stand is not the one with the most abilities, but the one its user knows how to use best.

Risks Consuming a Rokakaka never guarantees a perfect result. The user cannot always control which part of their body will be used as compensation. In some cases, the consequences can be permanent. Therefore, the use of this fruit is usually considered a last resort. Worth Due to its scarcity and power, the Rokakaka reaches an incalculable value on the black market. Governments, criminal organizations, researchers, and Stand users are constantly searching for the fruit, whether to save lives, conduct experiments, or use its power for other purposes. Mysteries Despite numerous studies, many aspects of the Rokakaka are still unknown. It is unknown why it has the ability to perform Equivalent Exchanges and what the true origin of its properties is. Some researchers believe it is related to supernatural phenomena that are not yet understood. Conclusion The Rokakaka represents one of the world's greatest mysteries. Its ability to defy the limitations of the human body makes it an invaluable resource, but also an enormous danger. Anyone who decides to use it must remember one unbreakable rule:

The Rokakaka Fruit

What is Rokakaka?

The Rokakaka is an extremely rare fruit with properties capable of defying the natural laws of the human body. Its main power is to perform an Equivalent Exchange, a phenomenon by which a damaged body part can be restored in exchange for the sacrifice of another part.

Due to its extraordinary properties, Rokakaka is considered one of the most valuable and dangerous biological resources in the world.

Origin

The Rokakaka is a very rare plant species whose exact origin remains a mystery.

Its cultivation requires extremely specific conditions, so only a few people know how to grow it correctly.

For years, various organizations and researchers have tried to obtain it due to its enormous medical potential.

Equivalent Exchange

The Rokakaka's signature ability is to perform an Equivalent Exchange.

When a person consumes the fruit, an injury, illness, or damaged part of their body can be healed.

However, that recovery always comes at a price.

Another part of the body will suffer equivalent damage, potentially losing mobility, deteriorating, or even turning to stone, depending on the circumstances.

The Rokakaka never creates something from nothing; it simply exchanges one loss for another.

Properties

Among its known capabilities are:

• To heal serious wounds.
• Restore damaged organs.
• Eliminate certain diseases.
• Recover limbs in specific cases.
• Alter the physical state of the body through an Equivalent Exchange.

However, all these benefits require a proportional sacrifice.

Coexistence Most of these breeds remain hidden from the general population. Governments, organizations, and Stand users often hide any evidence of its existence to avoid chaos. As a result, most people believe that vampires, Pillar Men, and other species are mere legends, except for the thiren, who tend to coexist more with humans. Conclusion The world doesn't belong solely to humans. Throughout history, numerous races have coexisted, each with its own strengths, weaknesses, and cultures. Regardless of their origin, any individual with a strong enough will can leave their mark on history and become a legend in the bizarre world.

Thiren The Thiren are a humanoid race with animal characteristics. Each Thiren retains traits of a particular species, such as ears, tail, fangs, horns, fur, or senses far more developed than those of a human. Depending on their lineage, they may possess special abilities, such as superior physical strength, an extremely developed sense of smell, great speed, or outstanding reaction time. Despite their appearance, Thiren possess the same intelligence as a human being and can develop Stands, learn Hamon, or master Spin. In many regions they live integrated with human society, although prejudices against them still exist.

Men of the Pillar The Pillar Men are an ancient humanoid species that existed long before the development of modern civilization. Their intelligence and physical capabilities far surpass those of any human being. They possess exceptional regeneration and can modify their own body structure to adapt to combat. Unlike vampires, they are the original species from which much of the research related to the Stone Masks emerged. Its main weakness is also sunlight.

Vampires Vampires are humans transformed through an ancient supernatural method. They possess physical strength far superior to that of humans, extraordinary speed, a great capacity for regeneration, and a long lifespan. However, they are extremely vulnerable to sunlight and Hamon, as both produce the same destructive effect on their bodies.

The Races of the World Although the majority of the world's inhabitants are human beings, there are diverse races and species that have remained hidden for centuries. Some arose naturally, while others were born as a result of supernatural phenomena. Each possesses its own unique characteristics and abilities. Humans Humans make up the majority of the world's population. Although most people live normal lives unaware of the supernatural world, some awaken a Stand, learn Hamon, or master Spin. A human's strength depends not on their race, but on their determination, willpower, and training.

The Golden Rotation The most advanced form of Spin is called Golden Spin. This technique uses the proportions of the Golden Spiral, a pattern constantly present in nature. When the user manages to reproduce that perfect rotation, they gain access to a power far superior to conventional Spin, capable of generating extraordinary effects that defy the normal laws of physics. Due to its enormous difficulty, very few people are able to master this form of Spin. Training Learning to spin requires patience, coordination, and a deep understanding of movement. Practitioners train for years to control balance, speed, strength, and the exact angle of each rotation. A small mistake can cause all the energy to disappear. Strengths High precision. It can be used both to attack and to heal. It works with numerous rotating objects. It allows you to control the trajectory of the projectiles. Its most advanced level achieves extraordinary power. Weaknesses Spin depends entirely on correct rotation. If the turn loses stability or is interrupted, the technique loses effectiveness. Furthermore, it requires enormous skill and practice to master, so few users reach their full potential. The Spin in JoJo's World Spin is considered one of the most refined disciplines ever created. Although many see it as a simple combat technique, it actually represents a science based on the laws of nature and movement. In the hands of a true master, a simple steel sphere can become a weapon capable of rivaling far more extraordinary powers. Conclusion The Spin demonstrates that even the simplest movement can conceal immense power when perfectly understood. More than a fighting technique, it's an art that combines science, precision, and discipline, making it one of the most complex and elegant abilities in JoJo's Bizarre Adventure.

The Spin

What is Spin?

Spin is an ancient technique based on mastering perfect rotation. Unlike Hamon, which uses breath to generate energy, Spin employs rotational movement to produce a force capable of affecting both objects and living beings.

When a rotation reaches near-perfect equilibrium, it generates a special energy that can be transmitted to different materials without losing stability. Spin users take advantage of this principle to increase the power, precision, and versatility of their attacks.

Origin

Spinning originated centuries ago as a discipline developed and perfected in the Kingdom of Naples. It was originally used for medical purposes, as precise rotation could stimulate muscles, nerves, and joints without the need for invasive surgery.

Over time, the technique evolved into an extremely complex martial art, being used by both doctors and warriors.

Operation

The basis of Spin consists of producing a perfect rotation.

Any object capable of rotating can be used to channel this energy, provided the user is able to control the movement with absolute precision.

When the rotation reaches ideal equilibrium, the energy generated can alter the human body, influence objects, or modify the movement of whatever it strikes.

The more perfect the rotation, the greater the effect obtained.

Applications

The Spin has numerous applications.

It can increase the impact force of a projectile, change the trajectory of objects in full motion, immobilize parts of an enemy's body, stimulate muscles and nerves, deflect attacks, and even perform highly precise medical techniques.

More advanced users can control the rotation after launching an object, allowing them to modify its trajectory or maintain the effect for long periods.

Mastering the Hamon requires absolute discipline. The trainees perform breathing, endurance, balance, and concentration exercises for extended periods. The training aims to make the breathing pattern natural, even in extremely dangerous situations. Only those who remain calm under pressure can harness the full potential of Hamon. Strengths Highly effective against vampires and supernatural beings. It increases physical strength and endurance. It can be transmitted through conductive materials. It allows for highly precise techniques. It promotes excellent physical condition. Weaknesses The Hamon depends entirely on breathing. If the user runs out of air, loses consciousness, or their breathing is altered, the energy disappears. Furthermore, it requires a very long training period to reach a high level, so few people manage to master it completely. The Hamon today Over the years, Hamon lost prominence due to the emergence of Stands. However, it remains a respected discipline among those familiar with the history of the supernatural world. Although it is no longer as common to find teachers, some continue to pass on this knowledge to prevent it from disappearing. Conclusion Hamon represents the union of body, mind, and breath. More than just a power, it is a discipline that rewards perseverance, self-control, and determination. Even in an era dominated by Stands, Hamon remains one of the most elegant and fundamental techniques in the history of the JoJo's Bizarre Adventure world.

The Hamon

What is Hamon?

Hamon, also known as Ripple, is an ancient combat technique based on absolute breath control. Through a special breathing pattern, the user generates energy that flows throughout their body in waves, similar to sunlight.

Because this energy possesses properties equivalent to sunlight, Hamon is especially effective against vampires and other supernatural creatures vulnerable to the Sun.

Origin

The exact origin of Hamon is unknown, but it has been passed down through generations by masters and disciples. Throughout history, various warriors dedicated their lives to perfecting this technique in order to protect humanity from supernatural threats.

Learning Hamon requires years of physical and mental training, as well as near-perfect breath control.

Operation

The basis of Hamon consists of maintaining a constant and controlled breathing.

As long as the user breathes correctly, their body generates energy that can be channeled to any part of themselves or even to conductive objects.

If breathing is interrupted, the flow of Hamon decreases or disappears completely.

For this reason, preventing a user from breathing properly is one of the most effective ways to weaken them.

Applications

Hamon has numerous applications beyond combat.

It can strengthen physical blows, increase body resistance, improve reflexes, transmit energy through water or metal, heal minor wounds, and temporarily stimulate the functioning of the body.

The most experienced users are able to perform extremely precise techniques thanks to their perfect control of their energy.

Training

Mastering the Hamon requires absolute discipline.

The trainees perform breathing, endurance, balance, and concentration exercises for long periods of time.

Arrows are considered some of the most dangerous objects on the planet. Various criminal organizations, collectors, researchers, governments, and Stand users relentlessly pursue them. Whoever possesses an Arrow has the power to create new Stand users, disrupt the balance of power between organizations, and even alter the fate of entire cities. However, using an arrow is always risky. Every attempt can end in the target's death. Among all known Arrows, there is a special variant known as the Requiem Arrow. Unlike the others, this one can pierce a Stand directly instead of harming its user. If the Stand is compatible and manages to accept this power, it evolves into a superior form called Requiem. A Requiem Stand doesn't just increase its strength. It also develops an entirely new ability, usually related to its user's deepest desire or most urgent need at that precise moment. Because of this, each Requiem is different, and it's virtually impossible to predict what kind of ability it will gain. The exact origin of the Arrows remains a mystery. Although their connection to the meteorite is known, many questions remain unanswered. No one knows why this material can awaken Stands or what the true nature of the organism it contained was. For that reason, the Arrows remain relics shrouded in secrets. For some, they represent hope; for others, a curse. A single cut can transform an ordinary person into a powerful Stand user... or end their life in a matter of seconds. In the world of Stands there is a rule that everyone knows and respects: whoever controls an Arrow has the power to change the fate of the world.

The Arrows: The Origin of the Stands

In the world of Stands, there are objects whose importance surpasses any known treasure, weapon, or technology. These objects are the Arrows, ancient relics capable of awakening the hidden power of the human spirit.

Thousands of years ago, a meteorite struck Earth. Inside it was a strange organism or unknown agent with properties impossible to explain through conventional science. Long afterward, an ancient civilization used fragments of that meteorite to craft several arrows. Although they appeared to be simple metal weapons, each one retained a portion of the meteorite's mysterious power.

Arrows do not create power from nothing. Their function is to act as a catalyst that tests the soul of the one pierced by them. The instant a person is wounded, their body and spirit are subjected to an extreme test.

There are only two possible outcomes.

The first is death. If the individual does not possess sufficient spiritual strength, their body is unable to withstand the energy released by the Arrow and they die shortly thereafter.

The second is the awakening of a Stand, a physical manifestation of the person's will, spirit, and essence. Each Stand is completely unique, reflecting the personality, experiences, desires, and way of thinking of its user.

There is no rule that determines who will survive. Physical strength does not guarantee success, nor does intelligence or experience. What truly matters is strength of spirit.

Over time, countless legends arose about the Arrows. Some believe they possess a will of their own and are somehow able to choose those they deem worthy. Although this theory has never been proven, there are numerous cases where an Arrow seemed to react strangely to certain people.

Most of humanity lives without knowing that Stands exist. A Stand is the manifestation of a person's spirit, will, and potential. Not just anyone can see it; usually only other Stand users can. Not everyone awakens a Stand. Some are born with one, others obtain it through near-death experiences, extraordinary willpower, or mysterious phenomena. The Hidden Society There is a silent war. Organizations, mafias, governments, assassins, mercenaries, archaeologists, and collectors seek objects capable of awakening Stands. Ordinary people believe that disasters are accidents. Users know that there was almost always another Stand behind it. The Arrows Centuries ago, arrows were made from a strange meteorite. Anyone who survives an injury caused by one of them can awaken a Stand. Who doesn't... Just die. That's why arrows are some of the most valuable objects on the planet. Stand Rules Each stand is unique. It reflects the user's personality. If the Stand is damaged, its user usually is too. Most can only be seen by other users. No two Stands are exactly alike. Everyday Life Users try to hide their powers. A fight between Stands can destroy an entire street without civilians understanding what happened. The news reports about: Unexplained explosions. Missing persons. Impossible accidents. Absurd climatic phenomena. Murders without evidence. Users know that it was probably the work of another Stand. Dangerous Places There are areas where spiritual energy is extremely high. Things like the following can happen in them: Objects that develop Stands. Animals with powers. Conscious plants. Distortions of space. Mind-altering fogs. Many adventurers never return. The Users Not everyone is a hero or a villain. There is: Detectives. Doctors. Mafiosos. Musicians. Teachers. Police officers. Criminals. Students.
