Demon Slayeris filled with powerful sword techniques and samurai, known as demon slayers, who have perfected breathing styles inspired by nature’s elements. Among them, Flame Breathing is one of the most destructive and cinematically pleasing styles.

Kyojuro Rengoku, one of the strongest Hashira, mastered this style and showcased its full potential in his legendary battle against Akaza. Throughout the show, he showed viewers most of the different forms of Flame Breathing and put up a fight that almost killed the upper rank three demon.

The Origins Of Flame Breathing

Flame Breathing is one of the five major Breathing Styles derived from Sun Breathing; the originalcombat style created by Yoriichi Tsugikuni. It follows a powerful and aggressive approach, focusing on burning,sword-slashing techniques that resemble the movement of fire.

Historically,Flame Breathing was passed down through the Rengoku family, making it one of the most well-documented Breathing Styles in Demon Slayer. The technique emphasizes offense,cutting down demons with flame-like strikes.

While Flame Breathingshares its roots with Sun Breathing and was created by Hajime Oda, it evolved separately. Unlike Sun Breathing, which is highly versatile,Flame Breathing prioritizes wide-range attacks, making it ideal for direct combat against demons.

First Form

Unknowing Fire

A rapid, straightforward dash attack where the user charges forward and delivers a powerful flaming slash at the opponent.

Second Form

Rising Scorching Sun

A vertical, arching slash that moves upward, cutting off enemies while engulfing them in flames.

Third Form

Blazing Universe

A downward, fiery overhead slash meant to overpower enemies with raw force.

Fourth Form

Blooming Flame Undulation

A defensive technique where the user spins their sword in circular motions, creating a barrier of flames against attacks.

Fifth Form

Flame Tiger

A series of slashes that take the form of a rampaging flaming tiger, dealing multiple devastating strikes.

Ninth Form

Rengoku

The strongest technique, where the user charges at full speed and delivers a massive, flaming sword strike capable of cutting through enemies instantly. Used by Kyojuro Rengoku in his final battle against Akaza.

Flame Breathing And Sun Breathing

Flame Breathing exists because of Sun Breathing,but it lacks the full versatility of the original style. Yoriichi Tsugikuni,the creator of Sun Breathing and the strongest member of the Demon Slayer Corps,was the only known person capable of using its techniques perfectly.

When he tried to pass it on,his students could not replicate it fully, leading to the creation of derived styles likeWater, Thunder, and Flame Breathing.

Kyojuro Rengoku, the Flame Hashira, mastered this style to perfection. His father, Shinjuro Rengoku,once mentioned that Flame Breathing was a pale imitation of Sun Breathing, but this does not make it any less effective.

The techniques of Flame Breathing are still something to behold,both visually and in combat, as shown in Kyojuro’s fight against Akaza.

While Sun Breathing is considered the ultimate style,Flame Breathing remains one of the strongest combat techniques, wielded by warriors who burn brightly in the face of adversity.
