The Nine Sword Forms of Thunder's Roar

The location for the Demon Slayer Corps final selection is Mt. Fujikasane, where the mountainside and foothills are crawling with man-eating demons captured by official members of the Demon Slayer Corps!

The content of the Demon Slayer Corps official selection takes place within this mountain forest teeming with evil demons!

Survive for seven days!

Most of these evil demons are not particularly strong, but there are always those with exceptional natural talent.

Having endured round after round of selections, the number of young swordsmen eaten inside Mt. Fujikasane has grown and grown...

Until they transform into beings of such formidable strength that newcomers have no way to cope!

For example, the Hand Demon!

Of course, Kujo Tachibana feels that over these hundreds of years, the Hand Demon is definitely not an isolated case.

So how many young swordsmen, how many kendo geniuses, have died in vain here?

Who can guarantee that these currently ordinary swordsmen will not grow into Hashira-level members in the future?

These youths truly should not die here!

Kujo Tachibana feels that compared to the general public, these youths are more worthy of surviving at this moment!

Although this is somewhat cruel, the facts are exactly as they are.

Compared to having the Hashira execute demon-slaying missions to protect the public right now.

Kujo Tachibana believes they should instead come here to give these youths one more choice, and a chance to survive!

Watching this group of youths charging toward the foothills with indomitable spirit!

Kujo Tachibana sighs softly, then turns his expression resolute as he makes a vow in his heart:

"Brave youths! I will not let a single one of you die in vain on Mt. Fujikasane!"

"This is the promise of Kujo Tachibana!"

The reason Tachibana dares to make such a promise is also due to the security provided by his strength.

Following the footsteps of the young swordsmen, Kujo Tachibana sneaks into the mountain unnoticed by anyone.

Over this past year, the genius swordsman Kujo Tachibana has not been standing still.

At this moment, as his body gradually adapts to the breathing state of Thunder Breathing-Constant, Tachibana's physical fitness has skyrocketed compared to before!

And the growth in physical fitness has brought about a comprehensive enhancement of Tachibana's six senses.

At this time, Tachibana's Sword Heart Clarity domain has expanded to a range of three hundred meters!

It is comparable to "intermediate-level Observation Haki"!

Not only that, but even the forms of Thunder Breathing have been developed from the original six to nine!

"Thunder Breathing-First Form-Thunderclap and Flash!"

Channeling the power brought by Thunder Breathing into the feet and exploding it in one breath, it is a lightning-fast draw-slash that approaches the opponent at high speed like thunder tearing through the air, moving at a speed even demons cannot see, capable of severing a demon's head in a single strike!

It has extremely high requirements for explosive power in the feet; it is the most basic, yet also the most difficult move to learn in Thunder Breathing.

"Thunder Breathing-Second Form-Rice Spirit Modified!"

The moment Thunder Breathing is activated, unleash a series of lightning-shaped strikes at extreme speed!

The number of strikes depends on your will, and it can also be used to deflect attacks launched by an opponent.

"Thunder Breathing-Third Form-Gathering Mosquitoes Thunder Modified!"

Distributing the energy brought by Thunder Breathing to the limbs can improve one's own agility and speed, while leaving wave-like lightning along one's movement trajectory.

"Thunder Breathing-Fourth Form-Distant Thunder Modified!"

This was originally a melee skill that used the Nichirin Sword to burst forth lightning before rushing in front of the enemy.

After using it, Kujo Tachibana felt it was somewhat unreasonable, as too much energy produced by Thunder Breathing was wasted.

This skill was developed by Tachibana into a long-range attack skill that releases lightning directly using the Nichirin Sword.

Although it cannot kill a demon, it can cause a period of stiffness and paralysis to the demon!

It can be said that this is a long-range control skill.

"Thunder Breathing-Fifth Form-Heat Lightning Modified!"

This sword form can release lightning imbued with high heat onto the Nichirin Sword to increase the damage dealt to evil demons, while also carrying a certain paralyzing effect.

It works even better when paired with the "Red Blade" effect!

"Thunder Breathing-Sixth Form-Thunderclap Roar Modified!"

With oneself as the center, explode with all your power to instantly unleash countless lightning-shaped strikes in all directions!

It is also an enhanced version of the Second Form-Rice Spirit Modified!

It could also be said that this is Kujo Tachibana's most powerful area-of-effect skill currently!

"Thunder Breathing - Seventh Form - Electromagnetic Induction!"

This is a special method of using Thunder Breathing that was entirely original to Kujo Tachibana; in truth, this ability has nothing to do with swordsmanship, nor does it possess any offensive capability.

Rather, it is a method Kujo Tachibana developed based on modern electromagnetism to enhance his own sensory perception.

In fact, when Kujo Tachibana developed this technique, he originally intended to lean toward the direction of Magneto, using electrical energy to manipulate changes in magnetic fields.

It is a pity that the electrical energy brought about by Thunder Breathing in this world is still quite lacking.

Kujo Tachibana estimates that only the level of an awakened Goro Goro no Mi from the One Piece world could provide him with enough electrical energy to manipulate magnetic fields.

Although Kujo Tachibana's idea did not succeed, he discovered by accident that when he uses Thunder Breathing and attempts to influence the surrounding magnetic field reactions, it makes his electromagnetic perception within a radius of about one thousand meters exceptionally sensitive!

One must know that every living creature has its own unique electromagnetic reaction, and demons are no exception.

In other words, as long as a demon appears within a thousand-meter radius of Kujo Tachibana, he can find it through its electromagnetic reaction!

"Thunder Breathing - Eighth Form - Flying Thunder God!!"

Brothers, don't misunderstand!

This is not the Flying Thunder God of the Fourth Hokage!

It is merely a skill Kujo Tachibana created to pay tribute to his predecessor.

At the same time, it is a skill that can only be used by a dual-wielding swordsman; to put it simply!

It involves infusing the lightning-attribute energy brought by Thunder Breathing into the long blades, and then, this blade—which can continuously release electrical energy to paralyze enemies—is plunged into the body of a demon, causing the demon to suffer continuous electric shocks and paralysis-induced stiffness until the electrical energy in the long blade is exhausted.

Kujo Tachibana once used this move on a Lower Rank Demon, and the effect was quite good.

At the very least, Kyogai, the Lower Rank Six, was unable to move under this technique.

He was not turned into ash until the sun rose.

"Thunder Breathing - Ninth Form - Thunder-Drawing Blade!"

This sword form is one that Kujo Tachibana still has in the conceptual stage; he has not used it yet.

Why?

Because the conditions for releasing this sword form are extremely harsh!

And once successfully released, it is a case of inflicting a thousand wounds on the enemy while suffering eight hundred oneself.

To complete this sword form, it is best to choose a mountain peak or the highest point in the surrounding environment.

Thunderstorm weather is best!

Because this sword form cannot be completed by human power alone; it requires borrowing the power of heaven and earth.

The principle is to use Kujo Tachibana's own lightning-attribute energy, through the Nichirin Sword as a conduit, to draw down heavenly lightning!

Then, wrapped in the violent energy of this heavenly lightning, he cleaves through everything before him!

Of course, there is also the possibility of failure—either failing to draw the heavenly lightning, or his own body failing to withstand it and being struck dead by the lightning directly!

Kujo Tachibana estimates that if he were to truly unleash it, even if Muzan were to take this strike, he would have to hide for several more decades.
