Over the course of time, numerous individuals renowned as demon slayers have emerged and made their mark by standing up for humanity in its battle against demons. Yet, none can rival the enduring impact wrought by Yoriichi Tsugikuni.

Unquestionably, Yoriichi, a demon slayer of unparalleled power, accomplished feats that surpass the abilities of today’s top demon slayers. Tsugikuni battled some of the most formidable demons ever encountered and appeared almost invincible. Yet, what truly set him apart? To grasp Yoriichi’s greatness, it’s essential to delve into his origins and unique life experiences.

Born a Prodigy

Yoriichi’s Legendary Innate Powers

  • Manga Debut: Chapter 99
  • Anime Debut: Episode 45
  • Affiliation: Demon Slayer Corps

In the Sengoku period, Yoriichi Tsugikuni remained silent for the initial seven years of his life, leading his relatives to believe he was deaf. However, despite his reserved nature, he was always considerate towards others. Yoriichi held his older twin brother in high regard and had a particularly close bond with his mother.

Despite my father’s frequent coldness and criticisms, I hid this truth from the world. In my early days, there was nothing particularly striking about me, apart from my gentle nature. But that’s not what made Yoriichi the legendary swordsman he became. So, how did a seemingly ordinary man like me ascend to become the greatest swordsmith ever known? The answer lies in my journey beyond those years and the secrets I discovered along the way.

The Demon Slayer Mark

Despite appearing ordinary and drawing little attention, Yoriichi had an extraordinary birth. A mysterious mark adorned the left side of his face at birth, unbeknownst to anyone that it was the Demon Slayer Mark, which didn’t elicit much admiration initially. However, as Yoriichi matured, it became increasingly apparent that his physical prowess verged on superhuman capabilities.

As a captivated admirer might say, I’d be hard-pressed to keep up with the astonishing speed of Yoriichi. His reflexes were so sharp it felt like trying to hit a ghost in broad daylight. When he was just a lad, he could run for hours without breaking a sweat or even showing the slightest sign of fatigue. Over time, his endurance only grew stronger. To top it all off, Yoriichi possessed superhuman strength that left adults breathless when they encountered him in his youth.

Over time, Yoriichi transformed into a skilled swordsman and demon slayer, standing out like no other in the world. The Demon Slayer Mark gave him unbeatable strength, allowing him to conclude battles with a single powerful blow. One of its advantages was that it made his Nichirin Sword glow bright red, which nullified the regeneration of demon flesh, making them weakened instead. It’s worth noting that other swordsmen who acquired the Demon Slayer Mark didn’t match Yoriichi’s abilities completely; they could merely delay the regeneration of demon tissue rather than stopping it entirely.

Transparent World

Because Yoriichi had the Demon Slayer Mark at birth, he could enter the Transparent World earlier than most. This unique ability enabled him to observe finer details such as his opponents’ muscle movements, joint actions, blood flow, and respiration. In intense battles where timing was crucial for survival, this skill proved invaluable. Yoriichi exploited it effectively, making even formidable opponents like Muzan seem almost effortless to overcome.

Yoriichi’s Exceptionality

The Demon Slayer Mark greatly enhanced Yoriichi Tsugikuni, yet he remained humble about his inherent powers. True to his character, Yoriichi opted to pass on this mark to others upon joining the Demon Slayer Corps. However, the mark was accompanied by a dreadful curse – all who wielded it perished before reaching 25 years of age without fail.

My ideal was to reside peacefully with my family in a humble abode, where we’d share the same space. I longed to be near enough to catch glimpses of my wife and child’s cherished faces, close enough to embrace their hands whenever desired. Such simple bliss seemed attainable. Regrettably, it remained unrealized. Demons lurk in this enchanting world.

In this unique case, Yoriichi Tsugikuni stood apart from all other sword-wielders. Reaching a remarkable 85 years, one might speculate that the typical age limit didn’t pertain to him. This assumption arises due to his birth bearing the Demon Slayer Mark, a trait that others acquired through extreme physical exertion.

Inventor of Sun Breathing

The Origins of Sun Breathing

During the Sengoku era and long before, demon slayers didn’t have the advantage of using breathing techniques during combat because they hadn’t been developed yet. However, this changed when Yoriichi became a demon slayer and introduced Sun Breathing. The distinctive abilities that came with it allowed Tsugikuni to effortlessly control demons. In fact, even when confronted by Muzan, Yoriichi found it easy to overwhelm him without receiving any injuries in the process.

Sun Breathing consists of thirteen distinct methods, which Yoriichi had mastered and later passed down to the Kamado family. Ultimately, Tanjiro grasped its importance in combat and was the first Kamado family member to employ it in battle. All other breathing techniques were patterned after Sun Breathing, indicating that Yoriichi significantly influenced the development of combat skills for demon slayers, giving them a fighting chance against powerful demons.

Yoriichi’s Unrivaled Legacy

Muzan and His Forces Would Have Won Without Yoriichi’s Contributions

Yoriichi Tsugikuni, the founder of the Demon Slayer Mark, was instrumental in initiating the golden age of demon slayers. By helping fellow members of the Demon Slayer Corps obtain the mark, he put Muzan and his followers on the defensive. Subsequently, he developed Sun Breathing, a technique that eventually led to the emergence of other breathing styles over the following centuries.

It seems to me that from the moment I entered this world, I was endowed with an extraordinary power meant to vanquish Muzan Kibutsuji. However, despite my best efforts, there were areas where I fell short. Ultimately, I couldn’t prevent his reign, and as a result, countless lives were lost. This reality grieves me deeply.

Without Yoriichi’s significant accomplishments, it’s quite possible that the Demon Slayer Corps would have eventually succumbed to Muzan and his minions. Even though he is no longer physically present, his innovations and impact continue to serve as a beacon for other demon slayers.

For hundreds of years following Tsugikuni’s demise, numerous demon slayers have emerged and disappeared, yet none have approached his level of prowess, and it’s hard to imagine anyone ever will. It appears that Yoriichi not only achieved near-invincibility during his lifetime but also in death, as his fighting styles were preserved for centuries and managed to vanquish Muzan once more. This underscores the fact that true greatness can surpass mortal existence.
