Breath of Thunder Style (雷の呼吸,Kaminari no kokyū?) or Breath of Lightning Style, depending on a translation, is one of the five main breath styles directly derived from the Breath of Sun. The primary Cultivator for the Demon Slaying Corps is Jigoro Kuwajima. This technique increases the user's strength and agility to equal a demon's. There are a total of six original styles that can be used with the Breath of Thunder. Zenitsu Agatsuma was able to create a seventh style when confronting his former senior.
First Style: Thunderclap and Flash (壱ノ型霹靂一閃,Ichi no kata: Hekireki Issen?) - The user dashes forward and slashes at their opponent with incredible speed. Zenitsu has honed this ability to the extent of being able to repeat the dash multiple times in quick succession.
Six Fold (六連,Rokuren?) - This technique is primarily used by Zenitsu, it is a compilation of the First Style with a series of six dashes.
Eight Fold (八連,Hachiren?) - Zenitsu dashes eight times within one use of this technique.
God Speed (神速,Shinsoku?) - Zenitsu primarily utilises this technique, but the swordsman is able to augment the speed of the Thunder Clap Flash further. .
Second Style: Lightning Ball (弐ノ型稲魂,Ni no kata: Inadama?) - The swordsman is able to generate a series of five straight thunder attacks all performed in a single moment.
Third Style: Buzzing Mosquito Thunder (参ノ型聚蚊成雷,San no kata: Shiubun seirai?) - The swordsman is able to generate a spinning wave of lightning in all directions for a damaging attack.
Fourth Style: Distant Thunder (肆ノ型遠雷,Shi no kata: Enrai?) - The user is able to generate a ranged thunder strike at a distance.
Fifth Style: Heat Lightning (伍ノ型熱界雷,Go no kata: Retsu kairai?) - The user is able to generate slashing attack composed of lightning that cracks skin and burns flesh.
Sixth Style: Electric Lightning Shower (陸ノ型電轟雷轟,Roku no kata: Dengou raigou?) - The swordsman creates a series of thunder strikes that cracks the target's body.
Seventh Style: Flaming Thunder God (漆ノ型火雷神,Shichi no kata: Honoikazuchi no kami?) - This is the seventh form that was created by Agatsuma Zenitsu. The user creates a dragon-like creature emitting fire and thunder. This form alongside God Speed allows the swordsman to move extremely fast.
