Raijun Kaminari

**Raijun Kaminari** was a minor character in Demon Slayer: Blade of the Night. He was a personal friend of Yoriichi and Michikatsu Tsugikuni, and he was the creator of the Thunder Breathing, and the first Thunder Pillar in history.

## **Appearance:**

Raijun is a tall, slightly spindly man with neck-length black hair, which he kept in a low ponytail. His hair is quite spiky.

Raijun wore a yellow kimono, patterned with horizontal, darker yellow stripes, with black hakama pants. Due to it not being prominent yet, Raijun did not wear a Demon Slayer Uniform.

## **Personality:**

Raijun is a battle-ready man with a generally high-spirited personality. While not much is known about him on a deeper level, he is shown to be quite boastful, and not really care much for most things, such as how Ryo Yorunoha was able to use Moon Breathing techniques

Being able to discern the techniques themselves from a glance also shows that Raijun, for all his headstrongness, is quite an intelligent fighter in his own right. This mania for battle is revealed to be inherent to his personality, as his only regrets when crossing once more to the afterlife is that he wished to fight more.

## **Synopsis:**

Almost nothing is currently known about Raijun's past, other than at one point, he became one of Yoriichi's students, developing the Thunder Breathing.

## **Abilities:**

**Immense Strength:** Yet to be gauged, but a severely weakened Raijun was able to contend with Ryo Yorunoha in a short bout.

**Immense Speed:** Despite being severely weakened, Raijun was able to outmaneuver Ryo Yorunoha, to the point where he only got caught during a prediction, rather than a real reaction to his movement.

**Immense Durability:** Raijun, while yet to show it, can be surmised to be extremely durable.

**Total Concentration Breathing:** Raijun, as the first master of the Thunder Breathing, has mastered Total Concentration Breathing in order to grow beyond the regular limits of human biology.

**Demon Slayer Mark:** Composed of two lightning bolts appearing from his cheeks, pointing towards his mouth, Raijun has unlocked the Demon Slayer Mark, and the circumstances of his misuse of it are unknown.

## **Fighting Style:**

**Master Swordsman:** Raijun is an immensely capable fighter, being one of the slayers heralded as the "Golden Generation", and even while severely weakened, just his raw skill was enough to trouble Ryo Yorunoha.

## **Breathing Style:**

**Thunder Breathing** *(Kaminari no Kokyu)*: As the creator of the Thunder Breathing, Raijun is immensely capable in utilizing it, and alone, he was able to develop six entire techniques that are so all-encompassing that they have remained as the only ones until Zenitsu Agatsuma developed his seventh and those forward.

#### **Techniques:**

* **Thunderclap and Flash** *(Hekireki Issen)* - The user unsheathes their katana, dashes forward at blinding speeds and decapitates their opponent faster than they can react, before sheathing it back. This versatile Form can be used multiple times in succession, up to eight times.

* **Rice Spirit** *(Inadama)* - The user releases an uninterrupted series of five arched slashes in quick succession. This attack possesses great range and speed, the slashes can be done at any chosen angle, giving the user the option to go around or destroy the opponent's defences.

* **Thunder Swarm** *(Shubun Seirai)* - The user jumps up in a wave-like motion, surrounding the foe with continuous, incredibly long-ranged slashes from every single direction.

* **Distant Thunder** *(Enrai)* - The user draws their blade, slashing all around themselves in a defensive motion, proceeding to dash while slashing in a manner similar to the First Form. While more defensive, this form is slower and less accurate than Thunderclap and Flash.

* **Heat Lightning** *(Netsu Kairai)* - The user unleashes a quick, long ranged upwards slash, causing immense damage. This attack is incredibly heavy, despite its speed. The user can utilize the momentum to avoid any other attacks around themselves, or to increase the attack's strength.

* **Rumble and Flash** *(Dengo Raigo)* - The user unleashes continuous slashes mimicking the previous forms, combining their attacks into a chaotic vortex of attacks that devastates what it crosses, using dashes and slashes to strike all around themselves, the user turning into a storm itself.

## **Equipment:**

**Standard Nichirin Katana:** While it is unknown what happened to Raijun's original Katana, he once wielded a yellow colored Katana with a cracked yellow appearance, as expected for a Thunder Breathing master. His handguard was a black, four-pointed star shape, with a golden border.

## **Trivia:**

* Raijun's name is a slight deviation of the name "Raijin", and is composed of the kanji for [Rai], meaning "Lightning", and [Jun], meaning "Genuine/Pure". His surname, [Kaminari], means "Thunder"
* Kaminari isn't really his surname. His actual last name, and the reason why he abandoned it is unknown.
