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.
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.
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.
Yoriichi Tsugikuni is the creator of the Sun Breathing style and is also the strongest demon slayer that has ever lived. He existed nearly 500 years prior to the events of Demon Slayer and struck fear into the hearts of every demon he came across.

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.
Demon Slayer's season 3's latest episode has left fans on edge with Tanjiro's discovery of Yoriichi Tsugikuni's Type Zero sword.
Hinokami Kagura (Sun Breathing)
Some of the characters who have faced Yoriichi and survived
This happened due to a treatment that had gone wrong. While he was being treated, Muzan killed the doctor because he was not able to observe any results. This turned him into one of the strongest beings that could defeat multiple Hashiras in one go.
It is possible for a swordsman to use more than one Breathing Style technique at a time, allowing the user to take advantage of the advantageous aspects of both techniques. Tanjiro Kamado, for example, can use both the Water Breathing and Sun Breathing styles simultaneously.
Taught to him by Sakonji during his training in the mountains, it is one of the five main styles derived from Sun Breathing. Though Tanjiro succeeds in making use of Water Breathing throughout the early parts of his adventure, he eventually discovers that he's better suited for Sun Breathing instead.
1 Yoriichi Tsugikuni
Yoriichi was the very first user of the Breathing Styles and he came up with Sun Breathing, a powerful breathing form that is known to be the most effective against demons.
Those who have read the manga know that Tanjiro's powers grow exponentially towards the end of the series. His skill and overall combat abilities could be compared to that of a Hashira's. That being said, there is absolutely no chance for Tanjiro Kamado to be able to beat Kibutsuji Muzan.
So to compare Tanjiro's Demon form in which he's immune to sunlight, and also has the prowess of Sun Breathing, it would give him an upper hand, but still he would lose to Yoriichi.
12 Water Breathing: Seventh Form – Drop Ripple Thrust
In order to counter these fast-moving balls, Tanjiro's first move was to use the Drop Ripple Thrust. This form involves a swift stab at a target and was used to reduce the impact of an oncoming temari. It is also known to be Tanjiro's fastest thrusting technique.
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.
The last one on our list and the first former Hashira we meet in the anime is Sakonji Urokodaki, the former Water Hashira. He trained both Giyu Tomioka, the current Water Hashira, and Tanjiro Kamado, our protagonist.
Yoriichi Tsugikuni, the first demon slayer, is the founder and also the first user of Sun Breathing. But as per Demon Slayer's timeline, Tajiro Kamado is the only alive Sun Breathing user.
Yoriichi Tsugikuni is a Demon Slayer from 300 years ago, and the inspiration for Kotetsu's training doll.
Miraculously, the new Nichirin blade for Tanjiro is hidden inside a life-sized battle doll named Yoriichi Type Zero, which strikingly resembles the legendary Demon Slayer.
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.
