For Rengoku Kyojuro, the pressure from the Meikyō was even greater than that from Himejima Gyomei.
This is not only because Meikyō's Sharingan can perfectly seize every opportunity, but also because Meikyō's current Breathing Technique level has greatly improved compared to the past. He can not only Constant Breathing, but also quickly extract Chakra and absorb Natural Energy at the same time, and condense Senjutsu Chakra in an instant.
The previous pre-animation has completely disappeared, and his strength has improved to a new level compared to the past.
As far as Meikyō is concerned, Rengoku Kyojuro's strength is now not much different from Himejima Gyomei's.
His wrist strength, speed, and explosiveness might not be the best among the Pillars, but they would definitely rank in the top three. His overall qualities are extremely high. Now, combined with the most powerful Sun Breathing, his strength has also greatly improved compared to the past.
"Sun Breathing, Second Form: Azure Sky!"
Mars flew from Rengoku Kyojuro's mouth with each breath, and he brandished his long sword, drawing a sun in front of him with ferocious force as it slashed towards Meikyō.
The eyes in the Sharingan the Meikyō darted around, and while dodging the attack by turning to the side, she ignored Rengoku Kyojuro in front of her and quickly spun around on one foot, slashing her Nichirin Blade upwards backwards.
"Flame Breathing, Second Form: Ascending Blazing Flame!"
"Sun Breathing - Fourth Form - Illusory Rainbow!"
The two Nichirin Blade clashed once again.
The move "Illusory Rainbow" relies on a burst of instantaneous rotation of the body to achieve high-speed movement, leaving afterimages in place. At the same time, it uses the reflection of the blade and the light of the flames when performing sword techniques to conceal itself, thus achieving a teleportation-like effect to appear behind the enemy.
However, for Kyōjurō, who has the Meikyō with Three-Tomoe Sharingan, it was still possible to catch Kyojuro's figure when he used this move.
"These two guys... are both stronger than me! Whether it's the power of their moves, the speed that Kyōjurō just displayed, or Meikyō's terrifying eyesight, none of them are things I possess!"
Shinazugawa Sanemi watched the two fighting in the arena with a complicated expression, feeling both displeased and somewhat pleased.
He was unhappy because these two were stronger than him, who was originally second only to Himejima Gyomei. He was happy because his companions were stronger, which meant he could hunt down more and stronger demons.
"Sun Breathing, Sixth Form, Burning Bones, Summer Sun!"
Seeing that his moves were ineffective, Rengoku Kyojuro decisively launched a fierce attack, rapidly spinning and swinging his Nichirin Blade, creating an Uzumaki of flames in front of him.
"Flame Breathing - Fourth Form: Blazing Vortex!"
As a swordsman who has mastered multiple Breathing Technique, the more Meikyō fights, the more he can feel that Flame Breathing is the Breathing Technique closest to Sun Breathing, and many of its moves are very similar to Sun Breathing.
The same Uzumaki flame slash reappeared in Meikyō's hands. Relying on the Sharingan's powerful vision, he perfectly blocked every attack from Rengoku Kyojuro, and even had the strength to launch a counterattack.
"Flame Breathing - Third Form - Fiery Phenomena!"
"Flame Breathing, Fifth Form: Flame Tiger!"
Sun Breathing is the strongest Breathing Technique created by Tsugikuni Yoriichi, but Rengoku Kyojuro is not Tsugikuni Yoriichi.
Even though Kyōjurō's strength has greatly improved after learning Sun Breathing, he has gradually fallen into a disadvantage against Uchiha Myokage, who has been able to combine Breathing Technique with Chakra and use Senjutsu Chakra Uchiha Meikyō.
Not to mention, Uchiha Meikyō, who has the Sharingan, can see through almost every move Rengoku Kyojuro makes!
"Something's not right with Kyōjurō!"
Shinazugawa Sanemi's eyes narrowed as he watched the battle unfold.
Because at this moment, Rengoku Kyojuro in the face of Meikyō's attack had suddenly changed from being in a sorry state at the beginning.
"It's as if they're fighting on instinct! They're even starting to anticipate the enemy's movements, just like Uchiha Meikyō, who possesses the Other Shore Crimson Eyes!"
Tanjiro and Uchiha Meikyō shared the same feeling as Shinazugawa Sanemi.
The former felt that Rengoku Kyojuro's current state resembled that of his father when he Dance of the Fire God. Tanjiro also remembered that Tanjuro had told him that as long as he mastered the Dance of the Fire God to a certain level, he could perceive the transparent world.
"Kyōjurō... did he master the Transparent World under my pressure?"
After noticing this, Uchiha Meikyō Rengoku Kyojuro while using his Sharingan the breathing rhythm of the Sun Breathing and the flow of Natural Energy within his body.
The Sharingan is powered by Chakra, and even when using Senjutsu Chakra, Meikyō can still see the flow of Natural Energy within Kyōjurō's body.
The Transparent World is the ultimate technique in the Demon Slayer World, a "supreme level" that Akaza Upper Rank Three, could not reach even after hundreds of years of relentless effort. Mastering it is equivalent to having the ability to see through objects, sense things, and predict attacks.
According to Akaza, this technique can only be mastered when one's fighting spirit is cultivated to its peak, but those who have learned Sun Breathing are obviously not included in this category.
This can be seen from the fact that Tanjiro's father, Tanjuro, an ordinary person, could master the Transparent World by Dance of the Fire God.
Because this was originally Breathing Technique developed by Tsugikuni Yoriichi, a naturally insightful person, based on his own circumstances, in order to kill Muzan Kibutsuji. Practicing the Sun Breathing may be a way to develop oneself in the direction of Tsugikuni Yoriichi.
"Whoosh! Whoosh! Whoosh!"
After the battle ended, Rengoku Kyojuro was panting heavily. He then took the water bottle from Tanjiro's hand and gulped it down.
As for Meikyō, he stayed where he was, pondering the Sun Breathing technique that he had just Sharingan.
"Brother Purgatory, did you just enter a transparent world? My father, Tanjuro, mentioned this when he taught me Dance of the Fire God, and even asked me to memorize it."
Seeing that Rengoku Kyojuro had stopped drinking water and was wiping his lips with his sleeve, Tanjiro couldn't wait to ask.
"A transparent world? That's a very apt metaphor! But instead of saying it's transparent, I feel that 'Transparent World' would be a more appropriate description."
At this point, Rengoku Kyojuro closed his eyes again.
"Even with my eyes closed, I can still clearly 'see' you, and I can even clearly see what you are going to do next."
As Rengoku Kyojuro spoke, he also gave a special demonstration, perfectly synchronizing his movements with Tanjiro's.
Adding a setting: the special effects from the anime actually exist in the Demon Slayer World.
