It seems that Tanjiro still has a long way to go to master the Water Breathing technique. Giyu, on the other hand, as the current Water Hashira, has complete mastery over all 10 forms of Water breathing, as well as an 11th form that he created himself.
During the fight against Rui, in the face of absolute despair, Tanjiro pushes past his limits and unlocks a new form of breathing called the Hinokami Kagura.
Eleventh Form: Dead Calm ( 拾 じゅう 壱 いち ノ 型 かた 凪 なぎ , Jū Ichi no kata: Nagi?) - The personal creation of the current Water Hashira, Giyu Tomioka. The user ceases all body movements and enters a state of complete tranquility, deflecting, blocking and cutting any incoming attacks with imperceptible speed with their blade.
1 Tenth Form: Constant Flux/The Dragon of Change
The most powerful water move in Tanjiro's current skill set, this is a form that gets more and more powerful with each rotation that he puts in. It's number one on the list because it has, theoretically, no ceiling when it comes to its intensity.
Thirteenth Form
This move was devised by Tanjiro solely to defeat Muzan. After all, the twelve hearts that Muzan could move around his body needed to be downed in one fell swoop, which is why Tanjiro resorted to this powerful technique.
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.
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.
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.
Now, with Demon Slayer Season 3's Swordsmith Village, two more Hashira have come into focus: Mitsuri Kanroji and Muichiro Tokito.
So now, Tanjiro, the protagonist of the Demon Slayer series, has access to a sword that belonged to the best swordsman to have ever lived. This sword was in bad condition, but Hotaru Haganezuka took it upon himself to restore the blade to its former glory.
Demon Slayer's season 3's latest episode has left fans on edge with Tanjiro's discovery of Yoriichi Tsugikuni's Type Zero sword.
Giyu Tomioka Fulfilled His Promise to Protect Tanjiro
The Water Hashira, Giyu, survived the "Infinity Castle" arc after fighting beside Tanjiro against Akaza and Muzan. Though his sword was snapped by Akaza, and he lost an arm to Muzan, Giyu fought with Tanjiro and his fellow Hashira with everything he had.
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.
Giyu is a character with great defensive options. His unique parry move, Dead Calm, is quite useful to punish the enemy's attacks and start your combos.
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.
Talking about the ways to activate the bright red color of the sword, we all know Tanjiro has activated his Demon Slayer Mark, but this time, it was Nezuko's Blood Demon Art that helped him get access to the sword's remarkable ability. Yes, that's right; Nezuko has the ability to awaken a Bright Red Nichirin Sword.
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.
What yogis refer to as Moon Breath or Chandra Bhedana involves breathing in through your left nostril only. The left side of your body is thought to be associated with the nervous system, and so Chandra Bhedana has been traditionally used to calm it down and promote sleep.
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.
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.
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. There ya go!
When Demon Slayer's story begins, in Chapter/Episode 1, Tanjiro Kamado is 13 years old, which is younger than usual for many shonen heroes. While shonen is geared toward tween and teen boys, shonen protagonists tend to be 14 to 17 years old when the story starts, a relatable age for the target audience.
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.
