Initially, Tanjiro's accuracy and strength were not up to the mark, which is why Muzan was able to avoid his attacks. However, Tanjiro accurately performed the thirteenth form and inflicted a ton of damage on the Demon King.
The Thirteenth Form of the Sun Breathing Style is unique in the sense that it doesn't really have a name of its own. Rather, it's a combination of all the twelve forms present in this style, used in succession to maximize their power. This move was devised by Tanjiro solely to defeat Muzan.
Of the breath of the sun. Also tanjiro can create as many forms as he wants if he can get stronger. the 13th form is the combination of all 12 forms of the sun breathing -_- The user continously performs all twelve forms of the breath style in repetitive succession to increase the accuracy and agility of his movements.
Tanjiro attempts to combine all the forms to perform the Thirteenth Form by using the Sun Breathing: Dance and Raging Sun but is thwarted midway during Fire Wheel and is pushed back yet again. Unfazed, Tanjiro says he will connect all the forms as that's how they were designed to be and resolves to succeed.
Tanjiro Kamado, the main character of Demon Slayer: Kimetsu No Yaiba, has ten forms that he utilizes whenever he fights.
However, the thirteenth form is the one that would land the final blow on Muzan. This form is a repetition of every Sun Breathing form performed in succession that would kill Muzan by hurting all of his vital organs.
Tanjiro isn't Faster Than Zenitsu, not at all. He is Strong but Slow. So, Zenitsu Will Probably Chop Him Down to bits before tanjiro even pulls out his sword properly.
Tanjirō's resemblance to Yoriichi (like from Muzan's perspective), would trigger his memories and cause him to accept death. AND since its against Kokushibō and not Muzan, there's not poison that'll mess him up. So I would say Tanjiro would win.
Thirteenth Form: Dance of the Fire God?) - The user continuously performs all twelve forms of the breathing style in repetitive succession to increase the accuracy and agility of his movements while reducing fatigue.
The Eleventh Form is an original technique created by Tomioka, which is also referred to as Dead Calm. While there are ten known and established forms, the Eleventh is purely Tomioka's addition, allowing him to negate the attacks of the enemy by ceasing his own movements.
If you are talking about 13th form tanjiro, It would be a tough battle battle. But in the end, Tanjiro would win mid- high Diffculty against FP Akaza. Yes, Akaza is insanely strong, but against 13th form Tanjiro, he would lose 7/10 times.
Seeing into the Transparent World, Yoriichi discerned Muzan had seven hearts and five brains that change position within his body. Seeing his chance, he combined all his forms into a single attack, cutting through them all and overpowering Muzan completely.
The last user is Tanjiro Kamado, who learned the Breathing Style from his father, Tanjuro Kamado. Other people can learn this technique if taught by a Kamado descendant.
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.
Only the Kamado family wields the Sun Breathing; that's why Tanjiro remembers his father performing Hinokami Kagura. As mentioned in the latest episode, Sun Breathing was the first breathing style, and all other breathing techniques are derived from it.
Even 400 years later, Muzan's fear of Yoriichi remained fully intact, as simply laying eyes on Tanjiro's hanafuda earrings caused him to recall their clash.
But if we are talking about the human form, then it's a big fat NO, because Tanjiro has just mastered the Sun Breathing whereas Yoriichi is the inventor of it, also he's way more powerful and holds an unfathomable battle intellect, larger than any Demon Slayer in history, so in conclusion, no one is remotely close to ...
So in the end DEMON KING TANJIRO IS A WHOLE LOT MORE POWERFUL THAN YORIICHI. Also not to mention that Tanjiro is literally invincible I mean to be honest Tanjiro could beat anyone in all of anime and in other series bc of his IMMENSE power.
5) Yoriichi
Case in point: he was the only one who could single-handedly take on Muzan and drive him to a corner. Yoriichi would be able to defeat every single Hashira on this list without breaking a sweat. Such was his reputation and skill in swordsmanship.
So in a nutshell, Zenitsu wasn't able to master the other five forms, but later in the Infinity Castle Arc, during the battle with Kaigaku, Upper-Rank Six Demon, he created a Seventh Form: Flaming Thunder God.
Thunder Breathing has 6 standard forms in total, with the first form said to be the foundation for all the other forms. However, Zenitsu Agatsuma developed a Seventh Form in order to stand on equal ground with Kaigaku, his former senior disciple under Jigoro who had become the Upper Rank Six of the Twelve Kizuki.
Yoriichi was born with the Demon Slayer mark and prowess in swordsmanship. His powers were beyond comparison as he defeated Muzan once and had him on the verge of death until he managed to escape.
