Thunder Breathing (Zenshuchuten).png

The Thunder Breathing ( (かみなり) () (きゅう) Kaminari no kokyū?) is one of the five main Breathing Styles directly derived from the Sun Breathing. The Thunder Breathing combat style mimics swift strikes and movements of lightning and electricity and infuses it with the users swordsmanship. This combat style is very reminiscent of the real life sword style know as Iaijutsu.

It has been remarked by Zenitsu that this combat style focuses on channeling strength into the user's legs, and maximizing the output of every single muscle and blood vessel in them.[1] 

It was created from one of Yoriichi Tsugikuni's students who attempted to learn the Sun Breathing, but due to not being as innately powerful as Yoriichi, they were instead taught an alternated breathing style that focused on their individual strengths and weaknesses, which eventually evolved into the Thunder Breathing.[2]

The former primary cultivator for the Demon Slayer Corps was Jigoro Kuwajima.

Breathing Style Relationship Chart



There are a total of six original forms that can be used with the Thunder Breathing with the First Form said to be the foundation for the rest of them. 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 6 of the Twelve Kizuki, replacing Daki and Gyutaro.

Note: Since the second to sixth form is used by Kaigaku who uses electricity in conjunction with his sword attacks, it is unknown how a normal Thunder Breathing swordsman would perform these techniques.

  1. First Form: Thunderclap and Flash ( (いち) (かた) (へき) (れき) (いっ) (せん) Ichi no kata: Hekireki Issen?)[3] - The swordsman unsheathes their blade, dashes forward and aims to decapitate their opponent.
    • Six Fold ( (ろく) (れん) Rokuren?)[4] - A compilation of the First Form with a series of six dashes.
    • Eight Fold ( (はち) (れん) Hachiren?)[5] - Zenitsu dashes eight times within one use of this technique.
    • God Speed ( (しん) (そく) Shinsoku?) - Further augments the speed of Thunderclap and Flash. After the second time, his legs become useless. During the final battle against Muzan, Zenitsu is able to use God Speed more than two times.
  2. Second Form: Rice Spirit ( () (かた) (いな) (だま) Ni no kata: Inadama?)[6] - Kaigaku unleashes five electrified arching slashes in a single moment.
  3. Third Form: Thunder Swarm ( (さん) (かた) (しゅう) (ぶん) (せい) (らい) San no kata: Shūbun Seirai?)[7] - Kaigaku generates powerful electricity and simultaneously unleashes blinding sword attacks that surround the enemy.
  4. Fourth Form: Distant Thunder ( () (かた) (えん) (らい) Shi no kata: Enrai?)[8] - Kaigaku generates powerful lightning strikes in several directions with his blade.
  5. Fifth Form: Heat Lightning ( () (かた) (ねつ) (かい) (らい) Go no kata: Netsu Kairai?)[9] - Kaigaku unleashes a powerful ranged electrified sword slash upwards that burns the flesh of his opponent.
  6. Sixth Form: Rumble and Flash ( (ろく) (かた) (でん) (ごう) (らい) (ごう) Roku no kata: Dengō Raigō?)[10] - One of the most powerful Thunder Breathing techniques. Kaigaku releases a series of strong ranged electricity attacks that strike his opponent from multiple directions.
  7. Seventh Form: Honoikazuchi no Kami ( (しち) (かた) (ほの) (いかづちの) (かみ) Shichi no kata: Honoikazuchi no Kami?) [11] - This form is created by Zenitsu himself and is possibly Thunder Breathing's most powerful technique. Zenitsu's blade takes the form of a bright yellow dragon that seemingly emanates sparks of electricity and dashes forward at blinding speeds surpassing his God Speed technique and decapitates his opponent.

  • This Breathing Style is very similar to the real-life fighting style of Iaijutsu.
  • The First Form: Thunderclap and Flash is stated to be the basis for the other forms, which was all Zenitsu could learn and hone, while Kaigaku couldn't despite learning the other forms after it. Two unnamed Demon Slayers said that he wouldn't be able to master the others much.[12]
