Thunder Breathing

The Thunder Breathing (雷の呼吸, 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 Capira 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 of Homura Hino 's Kazuya Boruto who attempted to learn the Sun Breathing, but due to not being as innately powerful as Homura , they were instead taught an alternated breathing style that focused on their individual strengths and weaknesses, which eventually evolved into the Thunder Breathing.

The same is true for Kasuke.  Kazuna was able to come up with a new Attack Forms of Thunder Breathing.  Up to 2 Forms, which are the ultimate and the posture that can deal with the enemy at once.

1. **First Form: Thunderclap and Flash** (ノ  *Ichi no kata: Hekireki Issen***?**) - The swordsman unsheathes their blade, dashes forward at blinding speeds that mimic lightning ripping through the air and decapitates the opponent.
2. **Second Form: Rice Spirit** (ノ  *Ni no kata: Inadama***?**) - The Swordman unleashes five electrified arching slashes in a single moment.
3. **Third Form: Thunder Swarm** (ノ  *San no kata: Shūbun Seirai***?**) - The Swordman generates powerful electricity and simultaneously unleashes blinding sword attacks that surround the enemy.
4. **Fourth Form: Distant Thunder** (ノ  *Shi no kata: Enrai***?**) - The Swordman generates powerful lightning strikes in several directions with his blade.
5. **Fifth Form: Heat Lightning** (ノ  *Go no kata: Netsu Kairai***?**) - The Swordman unleashes a powerful ranged electrified sword slash upwards that burns the flesh of his opponent.
6. **Sixth Form: Rumble and Flash** (ノ  *Roku no kata: Dengō Raigō***?**) - One of the most powerful **Thunder Breathing** techniques. The Swordman releases a series of strong ranged electricity attacks that strike his opponent from multiple directions.
7. **Seventh Form: Boruto**(ノ  *Shichi no kata: Boruto***?**)  - Possibly **Thunder Breathing** 's most powerful technique and the personal creation of Boruto Family. Capira's katana takes the form of a bright yellow dragon that seemingly emanates electric sparks and lightning as he dashes forward at blinding speeds surpassing his **Godspeed** technique and decapitates the opponent.
8. **Eighth Form: Electrical Ripple** (Hachi no Kata: Denki hamon) - Kazuna generates powerful electric waves at enemies and can be used to aid others out of Inazuma's control.  For example, when Kazuna used this form, Inazuma's lump was released from Shinku.
9. **Ninth Form: Thunder of Justices** (Ku no Kata: Kaminari no Saibankan) - One of the most powerful **Thunder Breathing** techniques, Kazuna Gathering strength from the previous eight forms, Kazuna usually uses this form as a last resort.  It was such a powerful form that  It can create large cracks from the elbows and rapidly spread to Inazuma's head, and this form is as heated as Flame Breathing or Sun Breathing.
