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.
In terms of achievements, Tanjiro outsmarted Water Hashira with just his natural instincts and defeated a bunch of demons even before becoming a member of the Demon Slayer Corps.
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.
Tanjiro's Current Demon Slayer Rank Is Kanoe
Not many of the Demon Slayers' ranks are known as of Season 2, but there are a few. 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.
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. Demon Slayer is one of the most popular anime series going on right now.
8 Shinobu Kocho, The Insect Hashira
That being said, she's arguably the weakest Hashira when it comes to pure strength.
1. Gyomei Himejima. Gyomei Himejima, the Stone Hashira, is the strongest Hashira in the Demon Slayer corps in terms of strength and swordsmanship. He is the only person who uses spiked flails and an axe instead of standard swords to kill demons.
Nezuko's rankings in the popularity polls are as follows: Nezuko ranked 3rd place in the first popularity poll with 3,319 votes. Nezuko ranked 11th place in the second popularity poll with 5,000 votes.
With his improved combat skills and newly learned Water Breathing techniques, Tanjiro successfully decapitates two demons.
The eccentric and flamboyant Tengen Uzui is the current Sound Hashira. This Breathing Technique gives him echolocation and other advanced hearing abilities.
Nope,but at the last part of the manga,he overpowered some of the hashira. Yorrichi IS and Always the strongest in demon slayer. He is the only one that has the demon slayer mark over the age of 25,he ALMOST also beat muzan.
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 certainly did a lot of good with his Water Breathing techniques, but his ability to use Sun Breathing both gives him an edge in battle and allows him to stand out among the incredibly powerful Hashira he fights alongside.
Three Hashira Tanjiro never will beat in Demon Slayer
Giyu's mastery of his Breathing Style (Water Breathing Style) is quite literally unmatched in Demon Slayer. Even amongst his fellow Hashira, Giyu is unique in being the only one who develops a Breathing Style Form of his own.

Upper-Rank Five: Gyokko
As a fellow artist, Gyokko became distracted by Haganezuka's dedication to sword-polishing and opted to hold off on finishing off a wounded Muichiro. Tokito then manifested his Mark and effortlessly decapitated Gyokko with Mist-Breathing, Seventh Form: Obscuring Clouds.
Chapter 205 of Demon Slayer features a timeskip and mentions the death of Tanjiro three generations after the battle against Muzan. To sum things up, Tanjiro died fighting Muzan and was revived within seconds due to the transfer of blood from the Demon King to Tanjiro.
But time and time again, Muzan proves his battle prowness. Mixing his own blood with his attacks and creating a poison, Muzan seemingly kills Tanjiro.
However, she wasn't immune to the sunlight initially, as she got burned badly at first. 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.
The number one ranked Kizuki is the terrifying Kokushibo, whose six orange eyes mark him out as one of Demon Slayer's most striking character designs. He also bears a major resemblance to Tanjiro thanks to his red-tipped hair and flame-marked face, although that appears to be a coincidence.
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.
1 Muzan Kibutsuji
The Demon King Muzan Kibutsuji has seven hearts and five brains, making him one of the most intelligent characters in the Demon Slayer anime series.
Demon Slayer's Tengen Uzui is considered to be one of the weakest Hashira due to almost losing this fight, but the fact is that Tengen only looks weak when compared to the most overpowered Hashira.
Least Favorite: Obanai- he had so much potential, but he was barley used and most of that potential was wasted. The sad backstory wasn't able to redeem him for me, it felt kinda forced to make people like him.
