Eighth Form: Solar Heat Haze Solar Heat Haze is one of the most devious forms of the Sun Breathing Technique. In it, the user tries to confuse their opponent by running toward them at a high speed. While doing so, their attack seemingly engulfs itself in a haze of heat.
Sun Breathing has the second highest number of known techniques of all the breathing styles. It has twelve forms that can all be combined into an extremely powerful thirteenth form.
9 Ninth Form: Idaten Typhoon
The user performs a backflip and faces down on their opponent, unleashing a powerful circular blast of wind in the process that slices anything and everything under them.
Tanjiro commences the Sun Breathing: Thirteenth Form against Muzan.
Many Kimetsu no Yaiba fans deduce that Yoriichi is Tanjiro's father, but that isn't the case. However, Yoriichi is responsible for teaching Tanjiro's ancestors the Hinokami Kagura, which has been passed down for generations.
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. It's through Sun Breathing that all the other Breathing Forms have been derived.
"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.
Sixteenth Form: Moonbow, Half Moon
With Moonbow and Half Moon, Koshushibo brings a downpour of six extremely large slashes on the demon slayers.
The actual answer is a little more complicated, but essentially no, Genya is not a demon. According to the source manga: "Genya has a special ability. For a short amount of time, he can become a demon using his bite strength and his special digestive organs."
Twelfth Form: Flame Dance Form of Sun Breathing
While its name is majestic, the Flame Dance form of Sun Breathing is simple. It involves launching a strong vertical attack followed by a quick horizontal slash.
Tanjiro's connection to Yoriichi is not through blood relation, but through their similar appearances, which is due to the divine nature of Sun Breathing. (Also Read: Did Demon Slayer hire a Bollywood director for Season 3? Fans speculate!)
Unlike all other marks users in his era, Yoriichi was able to defy fate and lived to about 85 years of age (the average life expectancy during the era Yoriichi was presumed to have been born was between 30 ~ 50 years).
Is upper rank one Tanjiro's father? No, they are not related. Tanjiro, by PURE COINCIDENCE, heavily resembles Yoriichi Tsugikuni, the creator of Breath swordsmanship, the only other person to use Sun Breathing, and the only person Muzan ever feared.
Kokushibo was the final Upper-Rank to die during Demon Slayer's "Infinity Castle" arc. Muichiro, Genya, Sanemi Shinazugawa and Gyomei Himejima fought together against Kokushibo, though Muichiro and Genya were no match for him and were killed.
Sensing their despair, Doma offered a chance to him and turned both Gyutaro and Daki into demons.
Seventh Form: Flaming Thunder God) - The personal creation of Zenitsu Agatsuma. The user dashes forward at blinding speeds and unleashes a singular forward slash at a low stance, which is seemingly accompanied by a yellow Japanese dragon shaped like a lightning bolt.
This anime repeatedly shows viewers the clear difference in the strengths of demons and humans, and that teamwork is the only way to overcome a task that seems insurmountable. In conclusion, Tanjiro will not be able to kill Muzan by himself since the Demon King is far superior in every aspect of combat.
Jigoro was a former Hashira who practiced Thunder Breathing, which ended up giving him the title of "Roaring Hashira". Naturally, he was a very powerful demon slayer who successfully killed many demons. Unfortunately, he retired at the age of 35, when he lost his right leg in a fight with a demon.
She uses the Breath of Love (恋の呼吸 Koi no Kokyu) which is derived from the Breath of Flames (炎の呼吸 Hono no Kokyu) and her instructor was Shinjuro Rengoku the former Flame Pillar.
