Nichirin Swords change color depending upon the user, making each blade unique. They can be of many colors. Zenitsu's blade is unique in that its coloration does not form as a solid band but instead as a lightning motif down the length of the blade. The reason for this patterning is unknown; however, when giving Tanjiro his new sword, Hotaru remarked that the past wielder of the blade before its refinery must have been a very strong swordsman. Given this statement, it is implied that a stronger skill level can create patterns or slight changes in a Nichirin Sword's coloration. Japanese Spring Steel Amber Nichirin Blade Twin Sword of Tengen Uzui from Demon Slayer Kimetsu no Yaiba (Demon Slayer Swords) Kokushibo · Doma · Akaza · Nakime · Hantengu · Gyokko · Gyutaro · Daki · Kaigaku · Enmu · Rokuro · Wakuraba · Mukago · Rui · Kamanue · Kyogai The Stone Hashira uses a large axe chained to a heavy flail. Both of them are forged of the same material as a Nichirin sword. Though, as per Chapter 169, the material might be even more superior than many best-forged swords. Even Kokushibo’s demonic sword failed to cut through Gyomei’s chain.

However, Tengen does possess a caring side that is masked under his flamboyant façade, one he only shows to those that are extremely close to him, most notably his three wives, Makio, Suma, and Hinatsuru, who Tengen is shown to truly care for, praising and encouraging Makio and Suma after their undercover mission [12] and assuring Hinatsuru that she has completed her mission and telling her to get out of harm's way. [13] Furthermore, Tengen also declares that they must value their lives above all others as they are precious to him. After the events in Yoshiwara, Tengen also becomes more friendly towards Tanjiro, Zenitsu, and Inosuke. While we don’t get to see much of Kanae or her sword in action, it’s clear that her choice of weapon is not ordinary. She used a standard Nichirin sword with an orange flower handguard and a simple handle. But her pink blade held more power than anyone could see. Instead of only direct combat, Kanae used her sword to stab poison into the demons.

Tengen is one of the only known Demon Slayer and Hashira to retire due to being permanently disabled instead of death or age, the other being Jigoro Kuwajima.

Tengen is a very tall, broad-set young man with a heavy, muscular, lightly tanned skin frame. His hair is white and of uneven length, the longest waves touching his shoulders and is cut with three more prominent, shorter clumps, arching above his eyes on either side of his face to fall as bangs. He has very small maroon eyes that seem to slant inward, along with one long eyelash that falls to the far side of his nose. He also wears what looks to be red eye make-up around his left eye, consisting of alternating large and small dots that run inwards, towards his eye. Nichirin swords or katanas are special weapons that demon slayers use in this shonen anime. These Demon Slayer swords are tagged with the term “ Nichirin,” which denotes the metal they are made up of. This material is made of Scarlet Crimson Ore and Scarlet Crimson Iron Sand. The swordsmiths use this material and create swords on tall mountains where the blade faces direct sunlight for over a year.

Sound Breathing seemingly combines Tengen's heightened sense of hearing, his Musical Score ( 譜 ( ふ ) 面 ( めん ) , Fumen ?) technique, his shinobi expertise as well as his dual Nichirin cleavers and his anti-demon bombs. For some time, it became Tengen's habit to say that he was going to hell. This stopped after seeing his wives' reaction: with Makio getting angry with him, Hinatsuru crying for him, and Suma biting him. [3]
