It is a shorter version of a Nichirin sword that has two hollow ovals making the handguard and a brown handguard. When Genya fires his shotgun at the Upper Rank from a distance, Kokushibo manages to suddenly appear behind him before the pellets could reach where he initially was, before slicing his arm off the moment he arrived. Fourth Form: Shifting Flow Slash ( 肆 ( し ) ノ 型 ( かた ) 移 ( い ) 流 ( りゅう ) 斬 ( ぎ ) り , Shi no kata: Iryūgiri ? Created from his own flesh and blood, his body's immense durability and hardness allows it to be just as sharp, if not more so, as a normal Nichirin weapon made from Scarlet Crimson Iron Sand ( 猩 ( しょう ) 猩 ( じょう ) 緋 ( ひ ) 砂 ( さ ) 鐵 ( てつ ) , Shōjōhi Satetsu ? Furthermore, Gyomei's massive spiked iron ball was similarly ineffective in damaging his neck despite the Stone Hashira slamming his flail on Kokushibo's neck from above.

Muichiro is a young boy of short stature with a lean muscular build along with long, straight hair of a black color that fades to pale turquoise as it approaches his waist. As many fans may know, the “Demon Slayer” title directly translates to “demon-slaying swords” rather than the characters in Japanese. Muichiro is an air-headed individual who seems to constantly wander off in thought and is unable to focus on anything.Having originally taken after his father, he was shown to display a higher level of kindness and understanding, believing he should aim to do good for others if he wanted good to be done for him. We do not see the sword clearly in the Demon slayer manga or anime because of the godly speed of Zenitsu’s attacks.

Unlike regular swords, Nichirin swords also have the special ability to adapt their users’ combat techniques. Using his altered katana, Kokushibo swings upward, sending six curved slashes crashing down several meters in front of him, powerful enough to leave craters in their wake.At the center of the tsuba lies a striking design of three eyes surrounded by black veins, reminiscent of Kokushibo's demonic transformation. While he chose the life his brother stood against, Kokushibo didn’t leave his swordsmanship behind even after becoming a demon. He is more prone to making humans into demons if he considered them to be worthy of use or being respectful warriors with a sad past, and unlike Muzan and Doma, it was suggested that he genuinely valued their strength and sees them as birds of a feather to himself. Flesh Manipulation: Like all demons, Kokushibo possesses the ability to manipulate his own flesh to a high degree.

With all the detailed descriptions and mechanics out of the way, let’s take a look at all Nichirin swords in the world of Demon Slayer, along with their user and the Breathing technique they employ to take down demons. First Form: Low Clouds, Distant Haze ( 壱 ( いち ) ノ 型 ( かた ) 垂 ( すい ) 天 ( てん ) 遠 ( とお ) 霞 ( がすみ ) , Ichi no kata: Suiten Tōgasumi ?Kokushibo wears a purple and black kimono with the hexagonal patterns, and black hakama pants with a white obi. The two cleavers are connected with each other through a metal chain attached to their hilt, creating a bladed nunchuck-like weapon. Moreover, similar to Zenitsu, Rengoku’s sword also has a special pattern on its side: a long flame going along the length of a silver-colored blade on either side.

Kokushibo's human family name contains the Kun'yomi/reading of the kanji for "to inherit, succeed" ( 継 ( つぎ ) , tsugi ? His speed could also easily outspeed the reflexes of Tanjiro Kamado, who was able to keep up with the movements of Upper Rank demons.While it is clear that swords and their close variants are the primary weapons for most characters on Demon Slayer, they are not the only weapon we see in the manga and anime. He is an adamant rule-follower, punctual, and he shows a great deal of respect to the hierarchy of the Twelve Kizuki, as seen at the Upper Rank gathering.
