Kyojuro Rengoku

It's the style Kyojuro Rengoku uses to fight, which is called Flame Breathing. His swordsmanship talent is such that he was able to master the first five different attacks of the style and use an ultimate attack.

First Stance: Sea of ​​Fire (壱いちノ型かた 不知火しらぬい, Ichi no kata: Shiranui?) - The user attacks his opponent at high speed, managing to decapitate his target with one or more cuts.
Second Stance: Sky in Flames Ascending (弐にノ型かた昇のぼり炎えん天てん, Ni no kata: Nobori en ten?) - An upward slash that Kyojuro used to cut off Akaza's arm.
Third Stance: Burning Spirits (ノ San no kata: Kien Banjō? ) - Kyojuro swings his sword downward in an arc.
Fourth Stance: Wave of Burning Flames (肆しノ型かた 盛せい炎えんのうねり, Shi no kata: Sei en no uneri?) - The user spins his sword in a circular motion to deflect the enemy's attack.
Fifth Stance: Fire Tiger (伍ごノ型かた 炎えん虎こ, Go no kata: Enko?) - A series of slashes that form the form of a tiger. Kyojuro was forced to use this technique to counter Akaza's Destructive Skill.
Ninth Stance: Purgatory (玖くノ型かた 煉れん獄ごく, Ku no kata: Rengoku?) - One of Kyojuro's most powerful and devastating attacks, causing massive impact and area damage.

Enhanced Strength and Stamina: Kyojuro possesses great physical strength and unparalleled stamina, being able to withstand the blows of a demonic upper moon, even earning its recognition.
Enhanced Speed: In addition to his strength, Kyojuro was fast. His speed was such that not even Tanjiro could keep up with him. His speed was so great that it caused tremors when he moved.

Of all the pillars, Kyojuro is the most enthusiastic, being by far the most aware of his mission, however, he could afford to be eccentric.

He is kind and boasts extraordinary technique and swordsmanship derived from strict practice and discipline. He is an honorable warrior who adheres to the code of morals and principles instilled in him by his mother at a young age. Most importantly, he believes that those born strong have a duty to protect the weak.

Kyojuro is a young man of barely 20 years old, with cream-toned skin, bright yellow hair with red streaks, forked black eyebrows, and golden eyes.

His attire consists of the regular Demon Slayer uniform along with a cape that has a white-yellow gradient pattern and red flame-shaped crests at the tips.

His hakama is fastened at ankle height with a pair of fabrics whose design resembles flames, zori sandals with red straps, and black socks. His Nichirin sword has a flame-shaped tsuba, and the blade of his katana is crimson red.
