How Strong is Tsugikuni Yoriichi in Demon Slayer

Note that this article includes spoilers.

The Demon Slayer (Kimetsu no Yaiba) is extremely well-known throughout the world. 

The antagonist of the manga, Muzan Kibutsuji, is one of the most powerful characters ever created in the manga due to his regeneration beginning after his body is cut off. He is much stronger than Piccolo of Dragon Ball.

In reality, there’s one more powerful character that outdoes the capabilities of Muzan Kibutsuji.

The swordsman was known as Yoriichi Tsugikuni.

Although he wasn’t an angel, he was the most powerful swordsman in the world, easily beating anyone else.

This article explains in detail the persona, capabilities, and strengths of this person. What makes him the most powerful swordsman of all time? 

Here’s a brief overview of Yoriichi Tsugikuni’s background and history.

Yoriichi Tsugikuni is the creator of Breathing of the Sun.

The first step is to examine the real identity of Yoriichi Tsugikuni.

His swordsmanship was so stunning that it was easy to forget to breathe. As Kamado Tanjiro once said, “The breath from Sun Dance is beautiful.”

It was invented by Yoriichi Tsugukuni. It was handed down from generation to generation in the Kamado family for many generations and was known as the “Hinokami Kagura” dance.

The “breathing from the sun” is the source of the term “basic breathing”. 

In the past, the pillars of the Demon Slayer Corps were strong, but they lacked blade techniques like wind and fire. So, one after another, Yoriichi Tsugikuni developed breathing techniques and adapted them to their specific swordsmanship.

Thus, the breath from the sun’s rays is referred to as the “breath that marks the start.”

In the days before the battle with the upper Rank 4 of the Twelve Kizuki, an action doll dubbed “Yoriichi Type Zero” was launched. 

The battle doll was inspired by Yoriichi Tsugikuni.In addition to the point, it is believed that the “mysterious swordsman” who is seen at the start of the tale is Yoriichi Tsugikuni. It was Yoriichi Tsugikuni who instructed and led the Demon Slayer Corps.

But, regardless of how gentle and meticulously Yoriichi Tsugikuni instructed them, nobody has been capable of mastering the sun’s breath after him.

He was a natural-born swordsmanship genius.

Yoriichi Tsugikuni was considered the strongest from the time of his birth until his death

Yoriichi Tsugikuni was the younger brother of a samurai family. For reasons unknown, he was born with a birthmark when he was just a newborn.

If a mark is visible, it enhances one’s physical capabilities.

He was astonished by his physical skills as a young man.

In reality, when he was just 7 years old, the boy developed the ability to see through the bodies of living beings. 

He was a caregiver for his mother, who was sick, and helped her throughout his early years.

At seven years old, young Yoriichi Tsugikuni easily overwhelmed adult swordsmen. 

No swordsman could compete with Yoriichi Tsugikuni’s youth. That’s how significant the effect of the marking was. 

The person who was marked would pass away at the age of 25. 

His physical abilities were much more formidable and he was also carrying a heavier burden on his body, which was immense.


Although he was carrying an inscription, Yoriichi Tsugikuni didn’t pass away too early.

Even though he had the mark, Yoriichi did not die until he reached the age of 80

As we’ll see in the coming days, his older brother, Michikatsu Tsugikuni, was attracted to his brother Yoriichi’s talent.

So Michikatsu Tsugikuni was transformed into a demon named Kokushibo, who was the most powerful of the six upper-ranked demons.

When he was in his twenties, Michikatsu’s brother, Michikatsu, was fighting alongside Yoriichi to take down demons as an ally of the Demon Slayer Corps. 

One day, Michikatsu created the mark. 

He is supposed to be content because Michikatsu will increase his power, but he needs to pay for the remainder of his time as a price. 

As a result, Michikatsu attempted to gain the trust of his brother Yoriichi by transforming into an undead.

The two didn’t meet for a long time following this, but they reconnected again 60 years later. 

At first, Yoriichi was expected to be dead at 25, but Yoriichi was now a “wrinkled aged man” and was able to reach the age of 80. 

Yoriichi received his birth with a bruised scar, but his body of his was “Natural Born Strong” and did not expire.

Thus, even after Yoriichi aged over 80, he was still in awe of Kokushibo, who was his brother.

Although Kokushibo was transformed into a demon of upper 1st rank, Kokushibo was no match for his older brother.

He passed away in the end due to “old age” and not due to battle injuries.

From birth to death, Yoriichi Tsugikuni was considered the strongest person in the world.

One of the main features in Yoriichi is Yoriichi’s “Crimson Red Nichirin Blade”. It is a red sword that shines red when it is heated. 

It could be said it is because the Red Sword is simply in an extremely hot state. The speed of regeneration for the demons cut by the sword is severely diminished, including Muzan Kibutsuji.

While the pillars of the modern age finally changed from the Nichirin Blade into the Bright Red Blade as they were dying, it appears that Yoriichi was always carrying his Bright Red Blade throughout his entire life. From this moment, we can predict the power of Yoriichi.

Muzan Kibutsuji was so powerful that he was close to killing Yoriichi Tsugikuni.

Muzan Kibutsuji

Yoriichi Tsugikuni nearly killed the creator of the demon, Muzan Kibutsuji.

Yoriichi Tsugikuni swung one blow after he was confronted by Muzan. 

Even though Muzan had multiple brains and hearts, they were all recognized by Yoriichi, who slashed the heart with a single blow.

Yoriichi’s lack of a killer’s energy resulted in Muzan becoming insecure and he was able to catch him. 

However, the difference in strength between them was apparent. 

Following that, Muzan, fearing that the death threat was imminent and that he would be killed, stayed in the house until Yoriichi passed away. Muzan is embarrassed by Yoriichi.

Muzan disintegrated his body into around 1,800 pieces to escape. 

However, Yoriichi cut off 1,500 pieces of splattered flesh to stop his adversaries from fleeing. Yoriichi is the strongest character in this particular scene.

It’s precisely the type of strength that could make Muzan a bit frightened by “the initial attack.”

They’re not equally equal in strength. If they’re equally matched in strength, there’s no way Muzan is going to back away from the fight.

Recognizing Yoriichi too much, yet refusing to concede that he was defeated by Yoriichi, Tsugikuni Muzan even stated:

“The true monster lies in man, not me.”

Wow! Yoriichi Tsugikuni is a very powerful and cool character!I love Yoriichi Tsugikuni! Thank you for visiting us.
