On the back of the shirt is a large kanji character in white, ”滅” (metsu, meaning extermination), representing the "metsu" in the Demon Slayer Corps name in Japanese which is kimetsutai (鬼滅隊 ). The hakama pants are also a simple all black color.
The members of the Demon Slayer Corps wear a uniform that is highly durable and light-weight. The uniform cannot be easily damaged by minor Demons. They sport their uniforms with a white belt and hakama pants, also wearing a white long-sleeved collared shirt under the uniform.
It isn't until later that we the audience discover that it is far more than just a scar. The mark on Tanjiro's head is actually a Demon Slayer Mark. Powerful Demon Slayers possess the ability to unlock unique marks that coincide with the special breathing fighting techniques they perform.
Demon Slayer symbol
This is a Kanji letter that appears on Demon Slayer uniforms, reading “METSU.” The symbol, according to experts, doesn't technically stand for “Demon Slayer,” but it does mean something similar to “Japanese demon” and “Annihilate.”
destroy, ruin, overthrow, perish. On: metsu.
AGATSUMA ZENITSU's name meaning in Japanese kanji symbol, Demon Slayer | Slayer, Demon, Japanese kanji.
Zenitsu's surname means "my wife" (我妻 agatsuma?), while his given name means "goodness" (善逸 zen'itsu?).
Muzan Kibutsuji (鬼舞辻無慘, Kibutsuji Muzan) is the main antagonist of the Demon Slayer: Kimetsu no Yaiba fantasy action manga and anime series. Muzan is the powerful King of all the Demons, who has the ability to inject his victims with blood that allows him to convert them into more Demons.
Lastly and most ridiculously, Muzan Kibutsuji. Kibutsuji means “demon dance road”. Yes, the oni kanji is right there on his name, same demon kanji as the demons everyone faces. And as mentioned in the opener, the name Muzan is literally just the regular word cruelty.
Muzan Kibutsuji (鬼舞辻 無惨, Kibutsuji Muzan) was the first and strongest demon in existence.
Tanjiro's ancestor was a good friend of Yoriichi and arguably was one of his only true friends. Therefore Yoriichi gave the earrings as a gift, and since then they have been passed down the generations until they reached Tanjiro.
During his second encounter with Muzan Kibutsuji, he injures his right eye in the Infinity Castle. As the battle progresses, Tanjiro suddenly collapses and his wound begins to form a large mass over his right eye due to the poison inflicted on him by Muzan.
To become a member of the Demon Slayer Corps, he had to clear the Final Selection. During this event, Tanjiro received a massive blow to his head from the Hand Demon that killed many of Urokodaki's students. This increased the size of his scar and changed the color as well.
Shinobu Kocho Is the Weakest Hashira
The Insect Hashira, Shinobu's petite frame prevents her from being physically able to decapitate any demon, be it an Upper-Rank or the weakest demon in Japan.
Yukire Hanazawa ( 花沢 はなざわ 雪 ゆき れ, Hanazawa Yukire?) is a Demon Slayer and the Ice Hashira ( 氷 こおり 柱 ばしら , Kōri Bashira?) of the Demon Slayer Corps.
Tanjiro's Current Demon Slayer Rank Is Kanoe
Tanjiro, Zenitsu, and Inosuke have moved from Mizunoto up to Kanoe due to their exploits. Murata, the Demon Slayer, who was almost digested on Mount Nagumo, is also a Kanoe.
The curse prevents Muzan's name from being spoken aloud, and any who do will meet a horrible demise. One demon, Susamaru, faced this reality when battling Tamayo. Susamaru accidentally shot Muzan's name aloud, attempting to defend his honor with her mind clouded.
During his final struggle, and as a way to slow down the effects of the sunlight, Muzan adopts an enlarged demonic infant form, approximately as tall as a 3 story building when standing up. In this form he has very pronounced blood vessels across his body, small claws in his hands and fanged teeth in his mouth.
The warrior Muzan feared was a swordsman named Yoriichi Tsugikuni. Yoriichi was the only slayer before Tanjiro who came close to killing Muzan, and the flashback of their fight occurred in Chapter 187.
After he neutralizes Tamayo's poison and emerges from his flesh cocoon, Muzan's hair grows in length and turns white due to Shinobu's poison accelerating his age.
Technically, the elder of the two Sakuras` was actually Muzan`s child, by way of his mistress (Lady Jade Wong), who had one of her eggs inserted into Anne`s body.
Demon Body: Unique from other demons, he possesses seven hearts, and five brains.
Nezuko Kamado
Zenitsu also protects Nezuko multiple times when she is in danger, evident during Zenitsu's first meeting with Inosuke Hashibira and the battle against Enmu in the train. Eventually Zenitsu and Nezuko would marry and start a family as evidenced by their descendants.
Inosuke Hashibira is one of the strongest characters in Demon Slayer despite not being a Hashira, the highest rank in the Corps.
So, as a result, it can be concluded that Zenitsu does not really have a split personality disorder, but instead sleepwalks, or rather, fights.
