Wonderful. The perfect physical form developed to the utmost. How long has it been since I've set my eyes on such a great swordsman, perhaps 300 years? After being beheaded by Sanemi Shinazugawa and Gyomei Himejima, Kokushibo evolved into a grotesque version of his Demonappearance, with protruding fangs, a pair of horns, and several sharp appendages from his body. With the Upper Ranks Kizuki appearing, the Hashira need to be properly prepared. Thankfully, they have their Nichirin weapons to help make the battle easier. Some wield the traditional katana while others have opted for modified versions or different weapons to better suit their fighting styles.

Kokushibo's human family name contains the Kun'yomi/reading of the kanji for "to inherit, succeed" ( 継 ( つぎ ) , tsugi ?) and "country" ( 国 ( くに ) , kuni ?), while his first name contains the Nanori of the kanji for "sterness, severity" ( 巌 ( みち ) , michi ?) and the Kun'yomi reading for "to prevail, victory" ( 勝 ( かつ ) , katsu ?). His father was the one who named him, as he believed Michikatsu would be strong and successful.There are more than 12 Nichirin-blade colors discussed in the manga of Demon Slayer. However, this isn’t the limit of possibilities. Demon Slayers come with their unique strategies, and there are numerous variations. There were minor color changes within the series, for instance, indigo-gray against amber, light pink, and yellow. A new color will likely be identified before the blade colors that are important to know have been recognized. If we compare the strength of Tanjiro to the strength, he’s displayed in the anime. It will be compared the strength of Inosuke and Zenitsu. Tanjiro is likely to become one of the strongest swordsmen globally, considering everything that has transpired in the manga and the development that Tanjiro has seen. Through Tanjiro’s Water Breath Style and Dance of The Sun God, along with the line of opening/interval and the ability to see Through, It is evident that he’s an experienced swordsman. Tanjiro has the ability and methods to shine shining. Kamado, the name of Tanjiro’s family, has roughly translated to “stove or furnace.” Giyu Tomioka The Demon Slayer’s personality, skills, and overall energy can be seen in the color change. The Demon Slayer with a strong and determined character may have their sword change color into red, orange, or yellow. Likewise, the Demon Slayer who is full of love might be gifted a pink blade. These colors permit the swords to be used as an extension that reflects the demon’s character and values. Kokushibo once killed a leader of the Demon Slayer Corps. This caused the Corps to put extreme effort in hiding the residence of future leaders. This event was also the one that caused the Kakushi to be formed.

He is the younger brother of math teacher Sanemi Shinazugawa. He once won 1st place in a competition but his brother stormed the place and ripped his certificate apart, all while screaming " Who cares about this shit?! Learn your damn math!!". Third Form: Loathsome Moon, Chains ( 参 ( さん ) ノ 型 ( かた ) 厭 ( えん ) 忌 ( き ) 月 ( づき ) ・ 銷 ( つが ) り , San no kata: Enkidzuki - Tsugari ?) [70] - Kokushibo performs two extremely broad crescent-shaped slashes directly in front of him, from which a storm of smaller crescent moon blades are released. Tenth Form: Drilling Slashes, Moon Through Bamboo Leaves ( 拾 ( じゅう ) ノ 型 ( かた ) 穿 ( せん ) 面 ( めん ) 斬 ( ざん ) ・ 蘿 ( ら ) 月 ( げつ ) , Jū no kata: Senmenzan - Ragetsu ?) [67] - Using his altered katana, Kokushibo creates three rotating circular saw-like slashes with crescent moon blades following their path. I could never grab hold of anything. Anything at all. I abandoned my home. I abandoned my wife and children. I abandoned my humanity. I cut down my descendants and abandoned being a samurai. But even all that wasn't enough? You said that those who master their paths all reach the same place. But I never did. I could not see the same world that you did. Why could I not leave anything behind? Why could I not become someone known? Why are we so different? Why in the world was I ever born? Tell me... Yoriichi... Demon Slayer Mark: Kokushibo awakened his mark when he trained under Yoriichi. [33] The Demon Slayer Mark drastically improves the abilities of an individual, making them much stronger and faster than what they can achieve normally, though at the cost of being cursed to die at the age of 25. However, by turning into a demon and gaining immortality, Kokushibo is no longer bound by the curse.Genya's surname contains the Nanori for "immortality, eternal life" ( 不死 ( しなず ) , shinazu ?) and the Kun'yomi rendaku for "river, stream" ( 川 ( がわ ) , kawa/gawa ?). His first name contains the Go-on'yomi kanji for "mysterious, occultness" ( 玄 ( げん ) , gen ?) and the Kun'yomi for "all the more, increasingly" ( 弥 ( や ) , ya ?). To himself) " Can I do this? Can I be any use? Will he notice me right away again... and cut me in half so that's the end? Sanemi... I can't let him die... I definitely mustn't fail. Himejima... Tokito... If only I were stronger!! If I were a Hashira!! The more I want to help, the more my body stiffens up making it difficult for me to move. I'm scared... that I'm no use and can't protect my comrades. Why am I so weak? It's frustrating! It's frustrating to be weak." [7] Shinobu’s Nichirin sword appears like any other sword close to the hilt but instead, it is more like a Nichirin rod that ends in a needle-like tip. This tip looks similar to an insect’s stringer and injects Wisteria poison into demons. Meanwhile, only a small part at the bottom of the handle-end of the sword is like an actual blade. All in all, Kokushibo's defeat required the combined efforts of three powerful Marked Hashira (two of which awakened the Transparent World) with Bright Red Blades, a Demon Slayer capable of using Blood Demon Arts, and even then, the battle was narrowly won and cost the Demon Slayers' two lives, a feat that truly exemplifies the might of Upper Rank One.
