We will delve into the historical and cultural context of samurai to understand the significance of Kokushibo's metamorphosis.

Born Together into a Samurai Family:

Michikatsu and Yoriichi were born into a samurai family lineage.
In the Sengoku period, twins were considered ominous, and it was decided that Michikatsu would be the sole heir, and Yoriichi, who bore with a birthmark, planned to be sent to a temple at the age of ten.

The two were raised distinctly, with differences in their rooms, clothes, and education. Perhaps because of this, Yoriichi always clung to his mother's left side.

His Innate Swordsmanship However, one day, it became apparent that Yoriichi possessed an exceptional talent for swordsmanship.
This revelation positioned Yoriichi as the favored successor.
The kind-hearted Yoriichi, sensing he would become the heir, left home earlier than planned following their mother's death.

Intense Jealousy Towards Yoriichi After Yoriichi left, Michikatsu read their mother's diary.
He discovered that 'their mother's left side was becoming paralyzed, and Yoriichi had been supporting her.'

Yoriichi, who was thought to be merely clinging to their mother, was actually fully aware and supporting her.
This realization sparked intense jealousy in Michikatsu towards his genius brother.

Reunion with Yoriichi and the Path to Demon Slaying

After Yoriichi's departure, Michikatsu lived a peaceful life for over a decade with his own family.
However, one day, while camping, Michikatsu was attacked by a demon.
Yoriichi, unexpectedly, came to his rescue, leading to an unforeseen reunion of the brothers.

The reunited Yoriichi had become a person of impeccable swordsmanship and character.
Overwhelmed with jealousy again, Michikatsu, wishing to surpass Yoriichi, abandoned his family to follow the path of a demon slayer, just like Yoriichi.

Encounter with Muzan and Transformation into a Demon

As a swordsman, Michikatsu steadily grew, but he could never catch up to Yoriichi.
His death became imminent as the birthmark manifested.

Driven by his pursuit of strength, Michikatsu abandoned everything to become a demon, choosing to surpass Yoriichi.

For Kokushibo, becoming a demon was not just about gaining physical strength but also about transcending human limitations and weaknesses.

Rejection of Human Weakness and Mortality:

Kokushibo's decision to become a demon was also fueled by his rejection of human frailty and mortality.
As a human, he was constantly reminded of his limitations and the inevitable approach of death, especially as he bore witness to Yoriichi's extraordinary abilities.
Embracing demonhood was Kokushibo's way of denying his human vulnerability and escaping the shadow of mortality.

The Desire for Recognition and Superiority:

Deep down, Kokushibo's actions are motivated by a desire for recognition and superiority.
He yearned to be acknowledged, not just as a great swordsman but as the greatest, unrivaled by even his twin brother.
This desire was so strong that it led him to forsake his humanity in pursuit of a twisted form of validation and acknowledgment.

Conflict Between Pride and Guilt:

Despite his demonic transformation, Kokushibo battles with an internal conflict between his pride and the guilt of what he has become.
There are moments when his past human emotions surface, suggesting a sense of regret and internal conflict over his choices and the path he has taken.

Impact of Historical Context and Samurai Values:

Kokushibo's motivations are also deeply rooted in the historical and cultural context of his time.
As a samurai, he was brought up with values emphasizing honor, strength, and mastery.
These values, combined with the turbulent times of the Sengoku period, shaped his worldview and his understanding of power and success.

In conclusion, understanding Kokushibo's motivations is key to understanding his character as a whole.
His journey from a human samurai to a powerful demon is not just a tale of power and ambition but also a story of a man wrestling with his sense of self, his insecurities, and the choices that led him down a path of darkness.

To the Demon Slayer Corps, Kokushibo is more than just a formidable opponent; he is a symbol of the insurmountable power and terror that demons represent.

Kokushibo's Six Eyes:

A Manifestation of His Past and Desires

The most striking feature of Kokushibo is undoubtedly his six eyes, which emits a powerful impact.
When a human transforms into a demon, past events and thoughts often materialize physically on their body.

It is believed that Kokushibo's development of a six eyes is significantly related to the "Yoriichi Zero Form."
This particular transformation seems to embody his deep-seated memories and desires, especially those associated with his twin brother Yoriichi and the unattainable techniques he developed.

Six arms of "Yoriichi Zero Form"

The Yoriichi Zero Form, which appeared in the Swordsmith Village, was created during the Sengoku period lived by the Tsugikuni brothers. It was equipped with "six arms" to replicate Yoriichi's power.

It is highly likely that this Yoriichi Zero Form was used by Kokushibo (Michikatsu) for personal training during the Sengoku period.
Kokushibo, who spent his life obsessively striving to surpass Yoriichi, would naturally be the user of this form, considering his character and relentless pursuit of greater strength.

Kokushibo (Michikatsu), in his relentless challenge to surpass Yoriichi, continuously endeavored with the Zero Form.
The impression of the six arms was so strong that it is believed to have influenced Kokushibo's appearance when he transformed into a demon.

What is ”Moon Breathing”?

The Origins of Moon Breathing

"Moon Breathing" (Tsuki no Kokyū) is a breathing technique used by the swordsman Tsugikuni Michikatsu during the Sengoku period, who fought in an organization that would become the precursor to the Demon Slayer Corps.
His brother, Tsugikuni Yoriichi, later known as the swordsman of the "Beginning Breath," created the "Sun Breathing," which excelled as a sword technique against demons.
Although Yoriichi taught his fellow demon hunters these breathing techniques, none possessed the skill to master Sun Breathing.
Consequently, Yoriichi taught them breathing styles suited to their abilities, leading to the creation of the five basic forms derived from Sun Breathing: Flame, Wind, Rock, Thunder, and Water.

Tsugikuni Michikatsu could not master Sun Breathing either.

The technique he used was Moon Breathing, derived from Sun Breathing.

The Sole Practitioner of Moon Breathing

Tsugikuni Michikatsu was the only practitioner of Moon Breathing.
Failing to surpass Yoriichi and seeking to achieve greater heights as a swordsman beyond human lifespan, he was turned into a demon by Muzan Kibutsuji, who desired to create demons capable of using breathing techniques.
As a demon with regenerative abilities and inexhaustible stamina, Michikatsu, now known as Kokushibo, enhanced his physical capabilities with breathing techniques, becoming one of the strongest beings.
Kokushibo held the highest rank among the demons, Upper Moon One (Jōgen no Ichi) of the Twelve Kizuki.

The 'Hitbox' of Moon Breathing

For example, "Water Breathing" (Mizu no Kokyū) techniques appear as though water is flowing, but in reality, the damage is inflicted by the sword itself.
However, when Moon Breathing is employed, a crescent moon becomes visible, and touching this crescent moon inflicts damage on the opponent.
This 'hitbox' is wide and constantly changes in size and shape, requiring extensive practical experience and sharp senses to avoid.

Moon Breathing Forms and Techniques

A powerful single strike released in the blink of an eye.

Second Form: Pearl Flower Moongazing (Nino Kata: Shuka no Rōgetsu):

Third Form: Loathsome Moon - Chains (Sanno Kata: Enki Tsuki - Tsugari):

Eighth Form: Moon Dragon Ringtail (Hachino Kata: Getsu Ryūrinbi):

A quick and powerful technique that carves out the surroundings in a single stroke.

Ninth Form: Waning Moon - Consecutive Faces (Kuno Kata: Kudarizuki - Renmen):

Tenth Form: Drilling Slashes - Moon Through Bamboo Leaves (Jūno Kata: Senmenzan - Ragetsu):

A technique where slashes approach the opponent as if scraping the ground.

Fourteenth Form: Calamity - Heavenly Thin Moon (Jūshino Kata: Kyōhen - Tenman Sengestu):

A technique that produces overlapping, spiral slashes, extending the range of the attack.

The Tragic Antagonist of Demon Slayer

In conclusion, Kokushibo, the 'Upper Moon One' of the Twelve Kizuki in "Demon Slayer," is a character of profound depth and complexity. Born Tsugikuni Michikatsu, his transformation from a human swordsman to a formidable demon is a journey marked by ambition, rivalry, and the pursuit of unmatched power.

His unique Moon Breathing technique, a derivative of the Sun Breathing created by his twin brother Yoriichi, stands as a testament to his relentless quest to surpass his brother's legacy.

The mastery of this technique, combined with his demonic powers, makes Kokushibo one of the most formidable adversaries in the series.

However, Kokushibo's story is not merely one of power and villainy.
It is a tragic tale of a man consumed by jealousy and the desire for recognition, leading him down a path of darkness.

His transformation into a demon, while granting him extraordinary abilities, also underscores the profound cost of his choices – the loss of his humanity and the eternal conflict with his own brother.

Kokushibo's character adds a rich layer of complexity to "Demon Slayer."

He represents the consequences of unchecked ambition and the tragic fallout of familial rivalry.
His impact on the narrative extends beyond his battles, contributing to the series' exploration of themes such as the nature of power, the dichotomy of good and evil, and the depths of human emotion.
