Shinobi world

In the use of ninjutsu there are several styles in which different ninjutsu of that style are included.
The basic styles are the elemental styles, which is the use of some chakra nature in the use of some ninjutsu, with each elemental style encompassing its own ninjutsu that work for a specific chakra nature.
When a keken or a Gen-kai is used, a style is also used, since these are treated the same as elemental styles as being derived or combinations of the basic chakra natures, therefore styles that use a keken or a Gen-kai are named according to the derived or combined element they use.
In the use of Taijutsu there are multiple styles which in this case are different styles of Taijutsu fighting, therefore each style of Taijutsu is different from each other but has the same foundations.
Animal styles are different types of ninjutsu that fall under the style of a specific animal. These styles are born and developed thanks to summoned animals, so learning to use an animal style goes hand in hand with having a contract with some species of Shinobi animal, since learning to use the style is not comparable to the species helping to develop it.
A person can also develop a style without it being related to any chakra nature or Shinobi animal simply by training and developing their own style; this is difficult to achieve, which is why it is also very uncommon, and the creator of the style can name it whatever they want.
There are some ninjutsu that do not use any style, either because they are very basic and do not require it or because they do not fit into any existing style.

All existing ninjutsu have a name which serves to efficiently identify each ninjutsu.
There is a formal way to pronounce a ninjutsu during its execution which is: Ninja art + style (if it has one) + type of ninjutsu + name of the ninjutsu.
Although there is a formal way to pronounce a ninjutsu during its execution, people commonly skip saying the type of ninjutsu to preserve the element of surprise when the opponent does not know the ninjutsu, only using ninja art + style (if it has one) + name of the ninjutsu.
Every Shinobi says the name of their ninjutsu when performing it, as this is also part of Shinobi culture and is therefore done without exception.
The names of the ninjutsu are always in Japanese (written in romanji to be understandable and the translation in parentheses to improve comprehension).

Inheritance of contracts
Contracts are not normally inherited automatically.
However, a master can teach a disciple how to make a new contract.
There are also Shinobi families that maintain contracts for generations.
This creates Summoning Lineages.
For example:
A clan may have maintained a contract with a species for three hundred years.
This creates a deep cultural relationship between the two.

How does the summoning work?

To perform a summoning, the Shinobi needs:

Sufficient chakra.
The corresponding contract.
Concentration.
The right hand seal.

The user places their hand on a surface and channels Chakra.

The contract recognizes the summoner and establishes an instant connection with the species' territory.

So:

Chakra → contract → territory → animal → human world

The creature appears at the selected point.
Summon size

An interesting feature of Kujutsu is that the size of the animal can vary.

The same creature can appear as:

🐭 Small size.
🐕 Normal size.
🐘 Giant size.

The size depends on:

Chakra used.
Summoner's intent.
Distance.
Type of creature.

Giant summons consume much more Chakra.
Hierarchy within a contract

A contract does not necessarily correspond to a single animal.

It can encompass an entire species.

For example, a contract with toads might allow you to invoke:

Tadpoles.
Small toads.
Toad warriors.
Teachers.
Seniors.
Kings.

Each one has their own personality.

That's why a contract can practically become an alliance with an entire civilization.

The hiring process
The traditional process has several stages.
Finding a compatible species
A Shinobi must first locate a kind of summoning.
Not all of them accept humans.
Some species:
They despise humans.
They consider Shinobi dangerous.
They only accept certain clans.
They demand proof.
They only accept people of a certain personality.
First contact
The Shinobi must establish communication with the species.
He usually appears before one of his most important representatives:
Old man.
Leader.
Guardian.
Teacher.
King of the species.
At this point the animal may reject it.
Compatibility test
Many species subject the applicant to a test.
These tests can measure:
Intelligence
To test if the Shinobi understands the nature of the species.
Character
To find out if it is:
arrogant
coward
cruel
honorable
compassionate
Ability
Some species require proof that the applicant can defend themselves.
Spiritual affinity
The oldest species can perceive the way in which the human Chakra interacts with nature.
Contract signing
Once accepted, the Shinobi places his name and signature on the scroll.
Blood is traditionally used to activate the bond.
The contract becomes connected to the user's Chakra.
From that moment on, you can use Kujutsu.

Summoning Contracts / Kuchiyose Keiyaku
Summoning Contracts / Kuchiyose Keiyaku are spiritual agreements established between a Shinobi and a species of Summoning Animal / Kuchiyose Dōbutsu.
These contracts allow the Shinobi to perform Kujutsu / Kujutsu [呼術], using Chakra to establish a connection with the contracted animal and bring it from its territory of origin to the place where the summoner is located.
However, the contract does not represent a simple master-pet relationship.
It is a pact between two conscious beings.
What exactly is a contract?
The contract is a Chakra bond between the Shinobi and a species.
When done correctly, the Shinobi's name is recorded within the Contract Scroll / Keiyaku Makimono.
The parchment serves as official proof that a bond exists.
However, the parchment does not compel the animal to obey.
That's extremely important.
The contract allows the connection.
The relationship determines whether the animal decides to respond.

What are Summoning Animals?
Summoning Animals / Kuchiyose Dōbutsu are special creatures that, although they have an animal appearance, possess characteristics much closer to those of an intelligent society.
Unlike normal animals, they can:
Talk.
Think in a complex way.
Learn Ninjutsu.
Use Chakra.
Develop your own techniques.
Forming companies.
Having families and lineages.
Creating traditions.
Establish hierarchies.
To have one's own territories.
They can reach enormous sizes.
Establish contracts with humans.
Teaching ancestral knowledge.
And, in certain cases, they can become masters of Zenjutsu.
The summoning territories
Each summoning species possesses its own territory, usually separate from the common human world.
These places are called:
Sacred Territory / Seichi
They are special regions connected to the natural flow of the world and, therefore, often contain enormous amounts of natural energy.
Each territory possesses:
Own geography.
Particular climate.
Exclusive flora and fauna.
Animal society.
Hierarchies.
Seniors.
Warriors.
Teachers.
Families.
Traditions.
Secret techniques.
Some territories may be:
Mountains.
Forests.
Swamps.
Deserts.
Islands.
Caves.
Lakes.
Volcanoes.
Valleys.
The leader of a species
The most organized species have a leader.
This may receive different titles depending on the species:
King.
Queen.
Great Elder.
Patriarch.
Matriarch.
Supreme Guardian.
The leader has the authority to:
Accept new contracts.
Breaking contracts.
Teach techniques.
Appoint teachers.
Prohibit invocations.
Decide who can access the territory.

Is it true immortality?
The answer is not completely.
The Shinsei call Karma immortality because their consciousness can survive.
But there are two ways to definitively get rid of one:
To destroy a vessel before it matures.
Kill the Shinsei when no vessel is available.
That makes Karma a conditional, not absolute, immortality.

Stages of Karma
First stage — Implementation
The Shinsei touches the victim and implants the Karma.
A dark mark with geometric patterns appears.
No transformation has yet occurred.
Second stage — Development
As time passes, Karma begins to expand.
The vessel experiences:
Physical changes.
Chakra Increase.
Strange dreams.
Fragments of other people's memories.
Without realizing it, he begins to resemble the Shinsei.
Third stage — Maturation
When Karma fully matures, the vessel ceases to be entirely itself.
The entire essence of Shinsei is already stored.
It is at this point that it becomes truly dangerous.
Fourth stage — Renaissance
If the original Shinsei dies:
His consciousness disappears from his previous body.
All its essence awakens within the vessel.
The body transforms into the new Shinsei.
It is not possession.
It is a complete reconstruction of his existence.
Limitations of Karma
Although it seems like immortality, it has very strict rules.
Not everyone can use it
Only some members of the Shinsei Clan possess this ability.
It is considered an extremely rare skill even among them.
Just a functional vessel
A Shinsei needs a prepared vessel.
If he dies before completing that process…
It disappears completely.
Maturation time
Karma takes years to complete.
During that time the vessel is vulnerable.
He may die.
It can be destroyed.
It can be removed before rebirth.
Signs of a vessel with Karma
As the seal matures, several symptoms appear.
Physical changes
Black marks that are spreading.
Iris alteration.
Increased resistance.
Abnormal Chakra Growth.
Mental changes
Memories that do not belong to the individual.
Dreams about unknown places.
Voices or thoughts of others.
Gradual loss of identity.
The person remains herself… until she ceases to be.

Karma
The technique that turns death into a temporary delay.
Karma is a skill exclusive to the Shinsei Clan.
It's not Ninjutsu.
It's not Zenjutsu.
It's not Fuinjutsu.
It is a biological and spiritual capacity unique to certain members of the clan.
Its purpose is to allow a Shinsei to continue to exist even after death.
What exactly is Karma?
Karma is a seal implanted on a living individual.
That individual is now called:
Vessel / Utsuwa
The vessel stores slowly:
The essence.
Memory.
The Chakra.
The full identity of the Shinsei.
It doesn't happen immediately.
It is a gradual process.
The vessel
A vessel is a living being prepared to become the new body of the Shinsei.
Could be:
Human.
Shinobi.
Any compatible species.
However, not just anyone will do.
Requirements for a vessel
It must have:
Large Chakra capacity.
A resilient body.
Spiritual stability.
Compatibility with Karma.
If the body is incompatible, the vessel dies before it is completed.

The Chakra cultivation system
The process followed by the Shinsei Clan never changes.
First stage — The seed
Two members arrive on a planet carrying a:
Seed of the Divine Tree / Shinju no Tane
The seed possesses its own life, but it needs a huge amount of Chakra to awaken.
Second stage — The sacrifice
One of the two Shinsei is turned into food for the seed.
The member considered weakest is usually sacrificed.
Their body, chakra, and essence are completely absorbed.
This sacrifice is not seen as a tragedy, but as an honor.
Third stage — The Divine Tree
Once nourished, the seed grows into:
Divine Tree / Shinju
The tree begins to absorb the Chakra of:
People.
Animals.
Floors.
The land itself.
Everything that possesses life ends up being slowly drained away.
Fourth stage — The Divine Fruit
When the tree has gathered enough Chakra, the following appears:
Divine Fruit / Shinju no Mi
This fruit contains the entirety of the cultivated Chakra.
Only a Shinsei member can consume it.
Fifth stage — Evolution
When the fruit is eaten, a transformation occurs that is known simply as:
Shinsei Evolution
It doesn't just increase power.
It also improves:
The ability to control Chakra.
Longevity.
Spiritual perception.
The stability of Karma.
Each fruit transforms the user into a superior version of themselves.

Philosophy of the Shinsei Clan
The doctrine of superiority
The Shinsei society is based on one central idea:
All the Chakra in the universe exists to be cultivated.
They believe that the planets are simply fertile lands where Chakra matures into a Divine Fruit.
From their perspective:
One world is not one home.
It's a crop.
An intelligent species is not a civilization.
It's a resource.
This philosophy explains why they destroy countless worlds without feeling any guilt.

Shinsei Clan / Shinsei Ichizoku
The beings who brought the Chakra to Earth… without ever having the intention of giving it away.
The Shinsei Clan is a civilization of beings from a higher spiritual plane. From their perspective, they represent the most evolved form of life and consider all other species to be inferior organisms whose only value lies in serving the cultivation of Chakra.
Unlike humans, the Shinsei did not develop Chakra: they were born completely synchronized with it, to the point of making it the basis of their entire society, technology, religion, and biological evolution.
Nature of the Shinsei Clan
What are they really?
The Shinsei are not gods in the strict sense, although many cultures have mistaken them for gods.
They are beings that possess:
An absolute connection with the Chakra.
An extremely long life expectancy.
A biology different from that of humans.
The ability to evolve through the consumption of the Divine Fruit.
For the Shinsei themselves, the concept of "mortal" is almost primitive, since they believe that true existence consists of continually transcending through the cultivation of Chakra.
Characteristic physical features
All members of the clan possess an elegant and almost supernatural appearance.
Their common characteristics are:
Very fair skin.
Hair of natural tones or completely white.
Eyes with luminous irises or unique patterns.
Horns, being the most distinctive feature.
Horns: a symbol of identity
Each member is born with a completely different pair of horns.
Horns function as a kind of genetic and spiritual fingerprint.
They may vary in:
Shape.
Length.
Curvature.
Symmetry.
Texture.
No two Shinsei share exactly the same horns.

TYPES OF NINJUTSU
Ninjutsu is divided into several categories according to its function and nature.
JUTSU
What it is: These are basic and fundamental techniques of every Shinobi; these are the techniques that every Shinobi commonly and generally uses since they do not have any specific focus.
GENJUTSU
What it is: These are techniques that focus on altering perception, mind, and reality through different types of illusions. They are primarily used as support techniques, but can also be used offensively if one has enough skill to make a Genjutsu feel real and tangible enough.
TAIJUTSU
What it is: Taijutsu consists of techniques with a completely physical focus; they do not depend on chakra like other types of ninjutsu, as this type focuses on different ways of fighting and only uses chakra as an enhancer, and Taijutsu has a wide range of different styles.
FUIJUTSU
What it is: These are techniques whose focus and purpose is to block, wax, protect, hide, seal, contain and prevent something from being used; they use chakra precisely to achieve this and depend heavily on the use of scrolls and seals.
KOJUTSU
What it is: These are techniques whose purpose is support since they are used to summon objects from one point to another, people or Shinobi animals, which is the main purpose of kojutsu.
SHIJUTSU
What it is: These are techniques focused on health, recovery, healing and cure of oneself or others by acting directly on the body, requiring surgical control of the chakra.
KIMJUTSU
What they are: They are different types of ninjutsu which are prohibited, restricted or limited because they are dangerous, can be misused, used for malevolent purposes among other reasons.
When a ninjutsu is performed, it is known as ninja art.

He is elected by:
the village council
the nation's chief feudal lord
This ensures that:
have internal power
have political backing

the name is taken from the village
It adapts with “Kage”
Example
Village: Hidden Village Among the Ashes / Hai Kakureta Mura
Leader: Haikage / Haikage

HIDDEN VILLAGES / Kakure no Mura

But beware:
They are not exclusive to them
There is also a civilian population.

Within a village there are:
active Shinobi
Shinobi in training
civilians
merchants
families
This creates a complex society, not just a military one.
Regarding the name “hidden”
They're not really hidden.
They are called that because their name follows a specific structure that refers to the environment where they are found.
Name structure
Hidden village + location
Example
Hidden Village Among the Ashes / Hai Kakureta Mura

Location: Base of an inactive volcano
identity: linked to ash.
Function within the world

circula
is distributed
it balances
How it works
The Chakra flows as constant energy
It fills the body completely
It keeps the vital and spiritual system active.
It is basically an internal network that connects the entire organism.
Importance
If this network:
It gets blocked → the flow is interrupted
It gets out of control → it can cause damage
It strengthens → the user becomes more powerful

CHAKRA
What exactly is Chakra?
The Chakra is a special energy that exists within all living beings.
But it's not something static, but rather something that:
flows constantly
circulates through the body
Connects body, mind, and life

most of the advances are concentrated there
There is greater access to technology
the quality of life is higher
Intermediate level
Medium-sized cities
Large towns
They have access to technology, but:
in a limited way
not as complete as in capital cities
SPECIAL CASE: HIDDEN VILLAGES / Kakure no Mura
The Hidden Villages are an interesting exception within the system.
Technological level
They possess a technological level similar to that of the capital cities.
Because
This is due to the direct support of:
Feudal lords / Daimyō
Result
High technical development
Constant resources
Strategic importance

POLITICAL DIVISION

Tradition (clans, lineages, honor)
Society (defined roles, structured communities)
Spirituality (energy, nature, beliefs)
Structural variety of the world
The world is not uniform. It is defined by a diversity of environments and settlements that create constant contrasts.
Types of places
Rural villages
Small towns
Medium-sized cities
Large capitals
Hidden Villages / Kakure no Mura
Isolated or hard-to-reach regions
Coastal and commercial areas
Each one has:
their own pace of life
its level of development
their access to resources
