Thunder Breathing

The Breath of Thunder (の) is one of the five main Breath Styles directly derived from the Breath of the Sun. It was created from one of Yoriichi Tsugikuni's students who attempted to learn the Breath of the Sun, but due to not being as innately powerful as Yoriichi, they were instead taught an alternated breath style that focused on their individual strengths and weaknesses, which eventually evolved into the Breath of Thunder.

It focuses on channeling strength into the user's legs. The primary cultivator for the Demon Slayer Corps was Jigoro Kuwajima.

Attacks
There are a total of six original styles that can be used with the Breath of Thunder with the first style said to be the foundation for the rest of them. However, Zenitsu Agatsuma developed a seventh style in order to stand on equal ground with Kaigaku, his former senior disciple under Jigoro who had become the Upper Moon Six of the Twelve Demon Moons, replacing Daki and Gyutaro.

Trivia

 * This Breath 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.
