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.
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.
This would have made him the Lightning (or maybe Thunder) Hashira. However, because he didn't have a pupil to take over for him at the time of his retirement, there is currently no Lightning Hashira.
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.
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.
Zenitsu creates his own form called Seventh Form: Honoikazuchi Nokami. Through this form, he is able to conjure a creature akin to a dragon that breathes thunder and fire. When combined with God Speed, his power and strength increase, giving him the ability to defeat demons like Kaiju, from the Upper Moon Six.
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.
1/7 Seventh Form: Honoikazuchi No Kami
This mastery allowed Zenitsu to form a Seventh Form of Thunder Breathing that is unique only to him: Honoikazuchi no Kami. While this move might seem similar to Thunder Breathing's First Form, the speed and power of this technique are on a whole new level.
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.
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.
Giyu Tomioka (冨岡 義勇) is a major supporting character in the popular anime/manga series Demon Slayer: Kimetsu no Yaiba. He is a member of the Demon Slayer Corps and is the current Water Hashira.
As a result, Tengen Uzui has to deal with the moniker of being the least powerful Hashira around.
She was ranked in 3rd place in the first Demon Slayer character popularity poll with 3,319 votes. IGN regarded Nezuko as one of the series's most popular characters and noted how her design elaborates the way she sees humans as good people as a result of hypnosis.
With all of that, what Zenitsu's true power is his spirit. Zenitsu might be a coward at times, flee from danger instead of facing it head-on, but when he's needed, he'll fight for his friends.
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.
Zenitsu Agatsuma vs Kaigaku is a battle that took place in the Infinity Castle. It focuses on the battle between Zenitsu Agatsuma against Upper Rank Six Kaigaku.
When looking at the symbolism in Japanese culture, sparrows represent 'the soft demeanor of deep thinkers' and are often considered to bring good fortune- and Zenitsu's name literally includes the kanji for good!
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.
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 after Daki unleashed an attack and harmed multiple people, Tanjiro was extremely angry at this that his eyes were turning blood-shot red.
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.
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.
