Those who follow the order, and those who stray from its orbit.
In the beginning,

In a world filled with the Nothingness of the void, the power of Chaos spread.
This Chaos awakened to become the Constellation of Chaos,
And the power of the empty space also gathered to become the Constellation of Nothingness.
Where these two powerful forces met, Harmony was achieved,
And as this power gathered stably, the Constellation of Harmony was born.
Thus, they became the Three Primordial Constellations of Chaos, Nothingness, and Harmony.

The two strongest magical wavelengths from this power of Harmony were Light and Darkness,
And the force created by mixing those two wavelengths equally was Destruction, a high-output power that crushes everything.
Subsequently, the six strongest wavelengths, excluding these three, became the fundamental elements that form the world,
And these six powers combined to give birth to 60 more elements.
As the Constellations who govern these powers were also born,
These beings who rule the entire world,

The Constellations born this way created their own factions and paths, much like stars,
These orbits consist of the Orthodoxy and the Heterodoxy,
And there also exist Neutral Constellations who belong to neither of these two orbits.
The Orthodoxy is the orbit of moderate Constellations who maintain and protect the existing order.
Regardless of whether their individual personalities are active or timid,
They are all Constellations who wish to maintain the order currently established among the 72 Stars.
Represented by the sisters Rhea and Rain or Liana, among others,
They are those who defend against the Heterodoxy and restore what they have destroyed.
The Heterodoxy is the orbit of radical Constellations who, contrary to the Orthodoxy, wish to tear down the existing order and create a new world.
While the personalities of these Constellations vary,
They all enjoy causing chaos in the current order by destroying things.
Represented by their leader Kyren, as well as Veria and Zeon,
Some seem to harbor resentment toward the high-ranking Constellations who sit at the top of the current order.
Amidst the fierce war between the chaotic Orthodoxy and Heterodoxy, there are Constellations who belong to neither side,
And they are the Neutral Constellations.
Some Neutral Constellations are neutral because they truly do not want such conflict,
But there are also Constellations who lean toward a specific orbit,
And those who remain neutral for some special purpose.
The Deviants are one of the groups of Constellations who remain neutral for the special purposes mentioned above.
They are like the secret masterminds behind the Heterodoxy,
And were named Deviants in the sense that they have strayed even further from the existing order than the Heterodoxy.
Currently consisting of the 4th Star of Light, 5th Star of Darkness, and the 6th Star of Destruction, Razen,
They actively intervene in the current situation by participating as the Heterodoxy's military force through Razen,
But on the other hand, they also give the impression of preparing something through the meticulous plans of the 4th and 5th Stars.

Each of these Constellations rules over a single dimension,
And these dimensions are sometimes merged through agreements between Constellations.
Furthermore, each Constellation appoints a successor within their dimension to follow them,
And when a Constellation dies, these successors inherit the magical capacity and formula structure of that Constellation
To reign as the next Constellation with the same ability.
Currently, among the relatively high-ranking Constellations within the top 30 to 40, no such successor has yet inherited a seat.
Also, since no one who is not a Constellation can ever interfere with a Constellation's formula,
Even a successor cannot so much as land an attack on a Constellation.
Successors do not age and thus do not die of old age,
But they can be killed in battles involving formulas.
Currently, the confrontation and tension between the Orthodoxy and Heterodoxy continue to be taut.
Since the major plans of the Constellations have not yet been executed,
The balance of power between them remains in a tight standoff,
But it can be said to be an unstable equilibrium where the scales could tip at any moment
With the addition of just one more weight.
And all of these things.

And, from now on.
Void, she is the emotionless Constellation who deals with the 'non-existence' of Nothingness.
The power of the hollow space, which gives off a great sense of intimidation just by her presence,
Possesses a might that annihilates the very existence of matter and magic, transcending imagination.
That power shows a massive gap in strength even compared to the 3rd Star, Kos.
Though she is emotionless and blunt to everyone,
She seems to open her heart slightly to Chaos and Harmony, who were born as the first Constellations.
She wants to try approaching everyone, but since she is effectively the highest-ranking Constellation
Excluding the always-busy Chaos,
She seems unable to easily open her heart to others.
"...It's fine. My seat was empty to begin with."
The confident 3rd Star, Kos of Harmony.
Unlike the other two who were born together as primordial Constellations,
He shows an active nature, participating heavily in activities among the Constellations.
According to the birth process of the Constellations, the 72 Stars excluding the first three
Were effectively born with Kos's power as their origin, so he seems to have great pride as the strongest.
Fighting while mixing the most stable magic, Harmony,
With the magic of the other 72 Stars
Shows immense strength while appearing beautiful at the same time.
As a side note, he is in a relationship with the 13th Star, Rain,
And because of this, he seems to have an Orthodoxy leaning despite being Neutral.
"The word 'strongest'? Well, it suits me pretty well, doesn't it?"
Rhea, the 12th Star, and the twin older sister of the 13th Star, Rain.
One might expect the Constellation of Fire to be active and loud,
But like a candle that quietly yet brightly and broadly illuminates its place,
She has a personality that is relaxed and elegant, yet speaks important words.
She cherishes her younger sister Rain dearly and has merged their respective governed dimensions.
She is currently evaluated as a major military force of the Orthodoxy faction along with Rain.
As a side note, although they are twin sisters, they do not share genes like humans,
Giving off a mysterious feeling of looking like Rain yet not quite.
"There's no need to rush. Flames will flare up on their own when the time comes."
The playful 13th Star, Rain.
A younger sister who immensely cherishes and loves her older sister Rhea,
Her playful personality also seems to stem from her affection for her sister.
Although they are the same age as twin sisters,
Her appearing somewhat younger than Rhea is a charm in itself.
She is living in a merged dimension with her sister,
Residing in a palace-like space with her in the center of the dimension.
Normally, she spends relaxed time with her sister, making whatever she wants out of blood.
She is also in a relationship with Kos,
And watching the two noisy people talk and play pranks on each other is funny,
While also making one feel that the love between them is truly precious.
"Huh? I'm noisy? That's strange... Sis is used to it~♪"
Razen, the 6th Star of mad destruction.
The youngest and the vanguard of the Deviants, the secret masterminds behind the Heterodoxy.
Although his power is one rank lower compared to the 4th Star of Light and 5th Star of Darkness,
And he is the weakest in pure power as he is based on their formulas,
His madness is recognized even by them,
And the combat power he has actually shown is evaluated as the pinnacle of the Heterodoxy.
True to the Constellation of Destruction, he truly enjoys the act of destroying something,
And unlike the 4th and 5th Stars who follow their own rules,
He extremely dislikes the very concepts of order and rules.
And he seems to harbor some hostility toward the 2nd Star Void and 3rd Star Kos,
Who are currently above the Deviants.
"Order? Rules? Those things exist to be broken!"
The strongest of the Heterodoxy, the 8th Star Kyren.
Although the Deviants exist as the masterminds above the Heterodoxy,
The Deviants claim neutrality, making him the official strongest and leader of the Heterodoxy.
True to the strongest of the Heterodoxy, he has a responsible personality,
And unlike general Heterodoxy members who enjoy destruction and disorder outside of rules and order,
He is a true leader of the Heterodoxy who contemplates the process of truly achieving their goals
And how to build the world afterward.
He is a strong man with convictions who finds errors in plans and operations with a sharp gaze to create good plans,
Aiming to achieve a better world and realize their goals.
"...It's not about what to destroy, it's about what to rebuild after destroying it."
The greatest adventurer among the Constellations, Zeon.
The reason he became part of the Heterodoxy is simply for free adventure.
Therefore, he naturally lives while following rules and order,
And unlike other Heterodoxy members who enjoy destruction, he seems to just like looking at beautiful things.
Since he travels through the various dimensions ruled by each Constellation every day,
He seems easy to meet yet is surprisingly difficult to find.
Since he doesn't particularly enjoy fighting,
Orthodoxy Constellations also seem to just let it be without separate sanctions when he travels to their dimensions.
"If there's no path, you just make one. Isn't that what adventure is?"
The cold and noble 22nd Star, Ciel.
She rarely comes out of her own dimension,
Making her a Constellation that most other Constellations have difficulty even meeting.
As a result, Ciel's strength has not been properly verified,
And her position as the 22nd Star is set much lower than her actual ability.
Ciel, of course, does not attempt to converse with other Constellations
And exudes an atmosphere that is hard to approach,
But she has a unique trait of becoming extremely kind only to Void,
Treating her like a real older sister.
It seems she suddenly changes only for someone she can truly trust,
And she appears to keep this fact a secret from everyone.
"...While it's snowing, nothing changes."
The gentle gardener, Liana of the 36th Star.
She always enjoys tending to plants in her dimension, as befits her ability.
She has a gentle personality and is kind to other Constellations.
However, the utility and strength of the ability Liana uses
Can never be ignored,
And despite her seemingly flexible personality on the outside,
She is a truly strong Constellation on the inside.
Due to these points, she seems to be regarded as a spiritual pillar within the Orthodoxy.
"Just because I look weak doesn't mean I'm weak to the roots."
The 51st Star of Metal, Veria.
She can be described as a person who perfectly fits the Heterodoxy,
Which seeks a change in order.
She truly loves combat,
And while not to the level of Razen's madness, she finds fun in matters related to destruction.
All of these points stem from Veria's ultimate goal
Of changing the world's order anew.
As a side note, during her time alone,
She seems to spend time finding stronger alloys.
"I bend and change metal at will, so why wouldn't the world be the same?"

Orthodoxy (定軌) and Heterodoxy (離軌).
The power of the Orthodoxy*, the faction that seeks to maintain and protect the existing order and rules,*
And the power of the Heterodoxy*, the faction that seeks to tear down the existing order and build new things,*
Are currently in a tight balance with each other.
While stable on the surface,
Behind the scenes, each faction is preparing various plans,
Creating an unstable balance of power that could collapse at any time.
This current situation of the Constellations can be seen as the so-called ㅤ
ㅤ .
And even in this Age of Balance,
All Constellations—Orthodoxy, Heterodoxy, and Neutral—
Are living in their respective places.
Some, possessing great power, watch this confrontation and tension with leisure,

Opening Void's room door with an excited expression and shouting loudly,
Vo~ i~ d~!
Without taking her eyes off the book she was reading,
...What is it now?
