Muzan is not afraid of a lot, but something about sunlight makes his skin crawl. What is so special about it?
Of the six eye -demon sword fighters -Kokushiboo
Brother of the legendary Yoriichi and the right demon to Muzan
In the Demon Slayer series it can be seen that Akaza does not get along well with cocushibo. In the past, Akaza Kokushibo challenged in one position for his upper moon, but was easy to overwhelm. Although Kokushibo usually absorbs the demons he kills, he didn't do it with Akaza because he presented a challenging fight. While Akaza threatened to kill Kokushibo, Kokushino just winced him and encouraged him to try this. This itself prepares the stage and shows Kokushios level of ability. As a former demon camp, Kokushio's combat style comes with its moon -fashioned technology, which was derived from the sun breath. After turning into a demon, Kokushibo became even stronger and also breathed his moon. His improved moon was gave him the ability to unleash large, crescent -shaped demonic slashes that could cut everything.
Akaza … you always go too far – Kokushibo to Akaza
As an upper moon One Demon, Kokushibo also had regenerative skills that enabled him to regenerate parts of his body immediately. Due to his years of experience as a former demon racket, Kokushibo was able to understand how Demon -Slayer could fight, and this gave him an advantage over other demons.

The chaotic and arrogant demon – Akaza
The martial art expert and the cold -blooded murderer
Akaza, Muzan's Obermond three demon, was a chaos and destruction power package. In contrast to Kokushibo, who used his sword, Akaza's combat style had more to do with martial art, which made him a mighty melee opponent. Akaza's blood demon art gave him skills such as destructive death, who merged his martial arts with powerful shock waves that he could control. He was also able to use a technology known as a compass needle that gave him the opportunity to feel the will of an opponent for fighting. This means that he can see an opponent's weaknesses and predict her next step. Akaza also had powerful regenerative skills, but still fought against opponents who had complex techniques and forces. He was also responsible for the death of Flame Hashira – Kyojuro Rengoku, but during this fight Akaza was seriously injured, although he was able to overwhelm Kyojuro and managed to flee before Tanjro was able to attack him.

Demon Slayer: Could Demons develop their own breathing techniques?
Breathing techniques are a secret weapon of demon sleepers in their fight against demons. But what if demons could also use?
While both demons are characterized by strength and strength, cocushibo is viewed as an undisputed stronger demon due to its superior skills and experience. While Akaza is more of a melee fighter, Kokushibo is characterized by his sword art and gives him an advantage in the fight for Akaza. The power gap is not only shown in their ranks, but also in their ability to accept Hashiras. In a 1 -1 fight between Akaza and Kokushibo, Kokushibo would most likely only occur as an overwhelming force for the manager together with its variety of demonic skills and its old knowledge that Akaza does not have.
