Since Kiriya Ubuyashiki announced the disbanding of the organization, Tanjiro doesn't get the chance to become a Hashira. The series also features an extended finale set in modern-day Japan.
8 Tanjiro Is The Only Living User
On the other hand, Sun Breathing can, presently, only be performed by Tanjiro Kamado. Though its techniques can be taught to others provided they have the guidance of a Kamado, there are no other known users who are currently alive.
Tanjiro's rank in the manga is unclear, but he is acknowledged as being Hashira level. He kills a recently enhanced Lower Six Moon Demon in his second major mission during the Train Arc and an Upper Six Moon Demon as early as the Entertainment District Arc.
In the memories, Tanjiro observes Yoriichi performing 12 of the Sun Breathing formations, which help him perfect his usage of the technique. It is thanks to Sumiyoshi that the movements are passed down through the generations and eventually become known as the Hinokami Kagura.
Tanjiro, Zenitsu, and Inosuke didn't become Hashira since they aren't ranked Kinoe, one of the requirements to become a Hashira. This's confirmed in Rengoku: Gaiden.
Tanjiro's Current Demon Slayer Rank Is Kanoe
Murata, the Demon Slayer, who was almost digested on Mount Nagumo, is also a Kanoe.
However, after the final fight with Muzan the Demon Slayer corps got disbanded. After Muzan was defeated, all the demons he created also perished immediately, so there was no point of a Demon Slayer corps anymore. As a result, Zenitsu did not get to become a Hashira even after becoming strong enough to bie one.
The Kamado family has a connection to Sun Breathing, the original and the strongest breathing technique in Demon Slayer. While Nezuko cannot use this breathing style, her ancestry may have influenced her fire-themed Blood Demon Art and allowed her to stand out from other demons.
Thirteenth Form of Sun Breathing in Demon Slayer
It involves a combination of all existing Sun breathing techniques — but performed in a consecutive manner. This technique's primary purpose is to slash all the twelve vital organs of a demon. Each form targets a specific organ. Tanjiro only used it once in the manga.
Shinobu Kocho is a capable Demon Slayer whose worthy of being the Insect Hashira. That being said, she's arguably the weakest Hashira when it comes to pure strength.
In his own franchise, Tanjiro is outclassed by most of the nine Hashira as of the end of season 1, including Giyu Tomioka. It's easy to compare Tanjiro's strength to Giyu's — since they are both demon slayers — and they even use the same element: water.
Tanjiro Is Strong, and Stronger than Zenitsu as he uses Sun Breathing.
Demon Slayer's season 3's latest episode has left fans on edge with Tanjiro's discovery of Yoriichi Tsugikuni's Type Zero sword.
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.
All other Breathing Styles are derived from it as the result of Yoriichi Tsugikuni, the creator of Sun Breathing, modifying it to suit the individuals he taught.
The flashback also reveals that Yoriichi had a twin brother named Michikatsu Tsugikuni, who became a Demon Slayer but later turned into a demon and became Upper Moon One, Kokushibo.
Moon Breathing is solely used by Michikatsu Tsugikuni, one of the first Demon Slayers who utilized Total Concentration Breathing, and is a Breathing Style which he continued using and perfecting after becoming a demon.
"Breath of the Sun: Thirteenth Style") is the thirteenth form the Sun Breathing and the pinnacle of all Breathing techniques in history. This technique was created by Yoriichi Tsugikuni himself in order defeat Muzan Kibutsuji.
So, in conclusion, her coming from a Sun Breathing user's lineage and not relying on human substance are perhaps the reasons for her immunity. Hence, Muzan was searching for the Blue Spider Lilly, a flower that was a crucial ingredient in the medicine used by the doctor who saved his life.
In episode 6 of Demon Slayer season 2, Nezuko entered a berserk state to protect her brother Tanjiro, causing her body to develop into that of an adult. She loses her gag, grows a single horn and gains vine-like patterns across her body.
Sunlight: Muzan is noted to be immune to being killed via decapitation, as seen when Gyōmei destroyed his head and he still managed to regrow it. Thus the only other known way that he can be destroyed is by sunlight.
Obanai Iguro is one of the harsher Hashira members. He demanded that Giyuu be punished for allowing Nezuko to get away unharmed, and later restrained Tanjiro as he tried to help his sister. He hates demons and has little regard for his fellow Hashira, except Mitsuri Kanroji later on.
Demon Slayers are known for their strength and bravery in battle, but not Zenitsu. Despite his cowardice, he's one of the strongest in the series.
There are six forms, but Zenitsu could only learn the first form said to be the basis for the others yet he honed it to where he could fight against several strong demons. He later created a seventh form and defeated his former senior who had become the Upper Rank Six of the Twelve Kizuki.
