The majority of anime fans are fairly familiar with Yoriichi Tsugikuni. The demon slayer character has influenced the popularity of the anime among its crowds of admirers.

Yoriichi Tsugikuni, regarded as the best demon slayer, was a tough warrior who created his fighting style. He perished while engaging in combat with his brother, who was later proven to be a demon.

Here is all the information you need to know about the fascinating anime character Yoriichi Tsugikuni.

Who is Yoriichi Tsugikuni?

Yoriichi Tsugikuni is a renowned Demon Slayer. He was the inventor of the renowned Sun Breathing technique.

It is the technique from which various breathing techniques have descended. Many characters use this breathing technique in the hit Anime Demon Slayer.

Yoriichi belonged to the corps of Demon Slayers. He is known as the first to employ breath, and like Tanjiro, he wore Hanafuda earrings.

The younger twin, Yoriichi, first seemed frail after birth. Since he was a shy youngster with exceptional emotional intelligence, he merely gave the impression of being weak. He was so unresponsive that everyone at one time assumed he was deaf. It now seems that wasn’t the case. Even his older brother took a long time to see Yoriichi’s actual power.

Yoriichi was born with the Demon Slayer mark on his forehead, signifying his incredible strength and combat skill.

Yoriichi’s mother, Akeno, intervenes to stop Yoriichi’s father from killing his son. After learning about this peculiar birthmark, he tries to kill his son and interprets it as a terrible omen.

When Yoriichi turns 10, his parents decide to enroll him in a monastery. Later, Yoriichi’s mother passes away, and he flees his home. He flees while racing through the day and night through the mountains without feeling worn out or exhausted.

The manga now starts to reveal hints of Yoriichi’s potential. He soon meets a young woman named Uta, who is around his age. Since Uta’s whole family has passed away, Yoriichi chooses to live with her. They married a decade later, and Uta conceives.


Yoriichi was composed and respectful, always wearing a grave and reserved countenance. He rarely displayed emotional outbursts. Most people could not discern his emotions because of his mild demeanor and constant expression. Only his wife, Uta, could do so without difficulty. Generally speaking, Yoriichi had a similarly quiet and calm demeanor.

The fact that he slew demons without changing his countenance shows this. Also, Muzan being astounded by his extraordinary talent as a result of his lowly appearance is evidence of this.

A good example of his humility is when he performed the Sun Breathing forms for Suyako at her request. He nearly seemed embarrassed afterward. Despite his godly qualities, he saw himself as another guy and no one exceptional.

He is largely indifferent, but he occasionally displays intense feelings. For ten days, he mourned the passing of Uta and their unborn child. Also, watching Sumire’s excitement at the straightforward act of being picked up brought tears to his eyes.

After his friend told him that his life was not meaningless, he too grinned genuinely and thanked Sumiyoshi. He then promised to pass on his Sun Breathing forms to his offspring. Yoriichi is also incredibly kind, as evidenced by the time he stopped on his way to pick up a midwife to aid an older man in reaching his dying son while en route. He did it in preparation for the birth of his child.

Powers and Abilities

Yoriichi didn’t receive formal swordsmanship instruction when he was younger, but it didn’t stop him from mastering the art. He could easily defeat a skilled swordsman after picking up his first one, demonstrating that he is a prodigy.

Yoriichi quickly became one of the most skilled and potent swordsmen in the Demon Slayer Corps.

Yoriichi is unquestionably a master with the sword, and he is in a class by himself. Yoriichi’s skill with the battle blade gives him lightning-quick speed. He nearly cut the infamous monster with just his blade during his battle with Muzan. He used no breathing exercises.

Yoriichi utilizes a special nichirin blade that transforms from black to crimson red. Yoriichi can use his weapon to burn any demon once it changes color and even stops them from being able to repair themselves.

With his sword, he has slain strong demons like Muzan. It frequently leaves them permanently damaged and unable to treat their severe wounds.

Most people consider this red nichirin blade one of the most potent weapons when fighting demons. Given Yoriichi’s exceptional fighting prowess and his terror of the sword, it is understandable why Muzan would feel this way.

Fighting Style

Yoriichi created the original Breathing Style. It is the style after which other fighters would model their styles. Sumiyoshi eventually reproduced this style and called it Hinokami Kagura. Yoriichi was extremely skilled at using Sun Breathing. He could easily defeat demons and even outmatch the Demon King and strongest Upper Rank. Tanjiro commented that Yoriichi appeared more like a spirit than a human when he used the Sun Breathing techniques. It was because the forms were so breathtakingly beautiful.

Is Yoriichi Tsugikuni the Strongest Demon Slayer?

Yoriichi is the strongest Demon Slayer known to have ever lived. He was born with the Demon Slayer Mark, Transparent World, and Selfless State, as well as a god-like body and a natural talent for swordsmanship. Most people describe him as a miracle prodigy beyond comparison. It was after easily defeating an experienced sword instructor at seven despite never having held a sword before. Yoriichi could beat many demons after becoming a Demon Slayer, to the point where his older brother claimed that he couldn’t match him as an adult.

What’s the Connection between Yoriichi and His Brother?

When Yoriichi was younger, he looked up to his older brother and regarded him with the utmost esteem. He also promised to emulate Michikatsu by becoming the most powerful samurai. When Muzan Kibutsuji transformed Michikatsu into a demon, tragedy sadly ensued. It made the brothers adversaries by default.

Are Yoriichi And Tanjiro Related?

The earrings and the Hinokami Kagura are Tanjiro’s family heirlooms. They were given to him and taught to him due to Yoriichi’s close friendship with Sumiyoshi, a distant relative of Tanjiro. Yoriichi is neither a blood relative of Tanjiro nor the Kamado clan no. The physical resemblance is coincidental. Yoriichi’s lone buddy was Sumiyoshi, and despite not being related, the two of them were quite close. Yoriichi was the main character from another period and the most potent Demon Slayer ever. He is popularly known as the creator of the Sun Breathing Style. Tanjiro awoke from his memories using that same style as he evolved into a Demon Slayer.

Why is Muzan Scared of Yoriichi?

Yoriichi never displayed bloodlust or malicious purpose as most fighters did when they were in combat. Instead, his cool demeanor made it hard for adversaries to read him or anticipate his maneuvers. It made Muzan fear the swordsman. Before Tanjiro, only Yoriichi, a slayer, had come close to murdering Muzan; a flashback of the battle occurred in Chapter 187. Muzan and Tamayo fought when Yoriichi came across them in a bamboo forest. Yoriichi’s Sun Breathing maneuver allowed him to behead Muzan and end his ability to retain information. However, Muzan immediately fled after being defeated, so he could not finish off the demon.

How was Yoriichi killed?

He lost his life fighting Kokushibo, the oldest of his twin brothers who had turned evil. He took the initiative in the conflict despite his old age and apparent blindness. Yoriichi cut his throat before he ultimately passed away, standing up, unharmed.

Who Is the Voice Actor Behind Yoriichi?

Kazuhiko Inoue, a living great in the world of voice acting, is giving the character’s voice. Fans will recognize Inoue as a talented actor from his roles as Gildarts in Fairy Tail and Kakashi in Naruto. Inoue has also contributed to other television series. They include Attack on Titan, City Hunter, Fruits Basket, and JoJo’s Bizarre Adventure.


One of the most admired and respected people in the “Demon Slayer” universe is Yoriichi Tsugikuni. He is known as a prodigy in the practice of Sun Breathing and a gifted swordsman. Yoriichi was the person who created the first Sun Breathing forms at the time.

He inspired many contemporary Sun Breathing practitioners. These practitioners highly regard him for his Sun Breathing forms.

We have no doubts you would love his character! You will love his character if you’ve not seen the demon slayer anime yet.
