Jigoro was the instructor of ZenitsuBelieving he was losing his master's favor, Kaigaku began to despise Zenitsu for being merely a weak and timid man who earned his master's favor out of dumb luck. Thus, he started to bully Zenitsu constantly. Later on, Kaigaku went on a solo mission to hunt down Kokushibou, the Upper Moon One, but was overpowered.https://villains.fandom.com › wiki › Kaigaku
A known cultivator of Thunder Breathing in the Demon Slayer Corps is the former Thunder Hashira, Jigoro Kuwajima.
Kaigaku (獪岳 Kaigaku) was a former Demon Slayer and uses the Breath of Thunder in the Kimetsu no Yaiba (Demon Slayer) series. After becoming a Demon he replaced Daki and Gyutaro and gained the position of Upper Moon Six of the Twelve Demon Moons.
Unfortunately, the answer to this question would be, no, he did not. Zenitsu, along with Tanjiro and Inosuke got way stronger than average corps members with training. In fact, he became one of the very few to even invent a new form of Thunder Breathing. However, his dream of becoming a Hashira was never realized.
After the deaths of Daki and Gyutaro, Kaigaku was promoted to become Upper Moon Six of the Twelve Demon Moons due to his power and confronted Zenitsu as a rematch he always desired.
10) Zenitsu
He certainly has speed and was able to keep up with Daki during the Entertainment District arc. While some might say that he could one-shot the Upper Moon demon Kaigaku, the demon was nowhere near the level of an Upper Moon since he was not used to his powers.
After mastering his Thunder Breathing, Zenitsu would eventually become capable of awakening his Demon Slayer Mark. As this mark would enhance his strength and speed, he can overwhelm Gyomei to a certain extent, but he still won't manage to defeat him.
While unconscious, Zenitsu is a force to be reckoned with, but his actual power is discovered when he is awake. While awake, Zenitsu was able to match the upper rank six, Kaigaku. He was also able to keep up with the Demon King, though he was in a weakened state during this battle.
Given how talented Tanjiro is, it's likely he'd defeat Zenitsu, even if the latter could fall asleep and call on his powers. Tanjiro's demonstrated his ability to take down more powerful demons and adapt to training on more than one occasion, so it just makes sense.
His second form is no exception, with Rice Spirit being a succession of five slashes that are accompanied by his black lightning. It's fatal to most opponents, although Zenitsu had the constitution and awareness required to avoid any major damage from this attack.
There are six forms, but Zenitsu could only learn the first form said to be the basis for the others yet he honed it to where he could fight against several strong demons. He later created a seventh form and defeated his former senior who had become the Upper Rank Six of the Twelve Kizuki.
Thunder-Breathing is a seldom-seen Breathing Style in Demon Slayer, but Zenitsu and Tengen just proved it's one of the strongest.
Yukire Hanazawa ( 花沢 はなざわ 雪 ゆき れ, Hanazawa Yukire?) is a Demon Slayer and the Ice Hashira ( 氷 こおり 柱 ばしら , Kōri Bashira?) of the Demon Slayer Corps.
Over a century ago, Doma held the position of Upper Rank Six ( 上 じょう 弦 げん の 陸 ろく , Jōgen no Roku?), and during that tenure, he turned Gyutaro and Daki into demons and introduced them into the Twelve Kizuki.
It was created by Kan'nari gō, one of Yoriichi Tsugikuni's students who attempted to learn the Sun Breathing, but due to him not being as innately powerful as Yoriichi, he was instead taught an alternated breathing style that focused on his individual strengths and weaknesses, which eventually evolved into the Thunder ...
Exploring Zenitsu's fighting abilities in Demon Slayer
Zenitsu has perfected the first form only and is seen performing it only when he's unconscious. But the manga shows that he can fight without fainting or going unconscious.
During the Hashira Training Arc, Zenitsu receives word that Kaigaku had become a demon, and that Jigoro committed seppuku as atonement.
The spider demon explains that the spider that bit Zenitsu earlier was one of his, and Zenitsu has been poisoned and will slowly start turning into a spider. As always, Zenitsu goes into a state of frenzy, and then he climbs a nearby tree.
When facing Kaigaku during the Infinity Castle arc, Zenitsu debuts his brand new exclusive Seventh Form to Thunder Breathing. With this, Zenitsu finally has more than one tool in his arsenal and has overcome his own personal doubts and fears.
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.
because zenitsu mastered it to the utmost limit.)
Akaza appears before Muzan and reports to him that he could not find the Blue Spider Lily, instead, he took down one of the Hashira. Muzan retorts it was only one Hashira and declaring his desire is for all to be dead. Angered at his failure, Muzan takes control of Akaza's cells and causes him to bleed heavily.
Akaza's appearance as a human at the age of 18.
Akaza. Because of his desire to become stronger and Doma's strength allowing him to surpass himself to become Upper Two, Akaza harboured an intense hatred of Doma. Doma, as apathetic as he is, considered him his "best friend", seemingly ignoring the contempt Akaza possessed.
