Thunder Breathing

Breath of Thunder Style ({{Ruby|雷|かみなり}}の{{Ruby|呼|こ}}{{Ruby|吸|きゅう}})
Although the origin of the breath style has not been specified in the manga, it is primarily taught by the former Pillar, 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. Later on in the manga, the Demon Slayer Agatsuma Zenitsu was able to create a seventh style when confronting his former senior.

 * Seventh Style: Flaming Thunder God (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.
