El's brownish-black eyes shone sharply, focused and determined, seeing that Enmu's tentacles had grown longer, some tentacles began to surround El and the rest targeted the passengers, like food on a serving table.
Despite all this, El didn't lose his focus, the sound of his calm and regular breathing began to echo the energy of the mist that enveloped his.
Each breath was heavy, yet full of meaning, as if the mist itself seeped into his body and merged with his soul.
In the silence, the cold aura of the mist began to envelop, creating a mysterious and calm atmosphere. The sword in his grasp felt so light, ready to glide at an unexpected speed.
"Kasumi no kokyū." In the next instant, like mist being lifted by the wind, his body shot out soundlessly, merging with the confusing and untouchable movements of the mist.
Slash! Slash! Slash!
Crot! Crot! Crot!
The reflection of the dim light on the train car's lamps made the black blade of Nichirin's sword in his grasp shiny, as it swung. El attacked Enmu's tentacles with high-speed movements, zig-zagging while performing a continuous barrage of slashes in front of or around his.
With a motion like a softly blowing mist, El continued to swing the sword from the eighth train carriage, towards the third train carriage, slashing at the Enmu tentacles that were trying to stop his from moving and targeting the passengers.
Click!
As if emerging from a thin mist on a foggy sea, El put Nichirin's sword in its sheath. Exhaling, it was as if a thin mist was coming out of El's mouth. "Go no kata: Kaun no Umi."
Unlike the previous slashes, each one launched a barrage of attacks.
When a mist breathing style user launches an attack, most demons may feel a sense of shock.
These attacks are usually accompanied by very fast and sudden movements, creating a sense of confusion as they try to understand what is happening. They may not even realize that they have been liberated.
This uncertainty can make them feel trapped in a dense maze of fog, making it very difficult to see which direction the attack is coming from.
As we know, each breathing style gives a different sensation, if hit by the slash.
Example Wind breathing style that can give a very painful ending to demons. When a slash of wind hits a demon's body, they will feel a sensation like being torn apart, as if being torn and crushed by a strong wave of wind.
Wind Breathing Style, having a sharp cutting power, makes demons feel a very sharp pain at the attack site and ache as they near the end of their lives.
Meanwhile, the Water Breathing Style will provide a calm and peaceful end to death. Once the demons are slashed, they will feel a sense of tranquility as they approach the end of their lives.
Despite the sensation of extreme pain, there is a feeling of acceptance, as if they are returning to the flowing water element.
Whereas the Fire Breathing Style would give an extreme burning sensation and a very sharp pain would flow through the entire body, giving a very stinging pain, as if their entire skin was being roasted by a raging fire.
But, among all the Breathing Styles mentioned, only the Sun Breathing Style gives such a painful sensation.
Sun breathing style attacks are famous for their incredible power and heat.
Once the slash hits the body, the demon will feel a burning sensation that is so intense, it's as if the sun's flames are burning every cell in their body.
For example, Muzan alone was rattled when facing the first sun-breathing user, Yoriichi Tsugikuni.
El turned her body around, looking at the passenger. There, El saw the impact of the results of using the Mist Breathing Style, if used against Demons.
"The attack power is quite very satisfying. The stamina drain is still very low."
"In accordance with the characteristics of the mist which is soft, invisible, and hard to predict. The mist breathing style is ideal for attacks that rely on speed, precision, and concealment, similar to the killing arts of the Nanaya clan of Type-moon."
Measuring in terms of speed and fluidity, the Mist Breathing Style can move silently and the user can also seemingly manifest themselves as mist.
According to El, if he cultivates the Fog Breathing Style to a stage higher than that of Muiichiro Michikatsu, then El can launch attacks at extremely high speeds while remaining hidden, utilizing this technique to disappear and attack opponents from unexpected positions.
In fact, among all the breathing styles available in the world of Kimetsu no Yaiba, El prefers the Fog Breathing Style because it can provide a disorienting optical illusion, seemingly masking the user's presence.
This would give them an edge in concealing themselves, moving without being seen, or even creating illusions that could outwit opponents.
Moreover, the sudden attacks of the Fog Breathing Style could be designed to perform surprise attacks.
El can seemingly emerge from the mist with a deadly slash before the opponent realizes his presence, allowing for an effective attack with little risk of being seen.
"The mist breathing style suits me when I'm performing Assassination. It's possible that this Breathing Style actually suits me instead of using the Sun Breathing Style which consumes a lot of stamina."
El frowned his head with a serious expression. "Perhaps, in the future I should study the Mist Breathing Style, before I can use Hi no Kokyū: Ju san no kata freely."
"After all, the Fog Breathing Style only has 7 moves. I've already mastered 5 of them."
"Mastering it to its highest point shouldn't be as difficult as the Sun Breathing Style. Moreover, I have Rinnegan's insightful eye ability."
"That way, learning to master any technique will be much easier!" said El with a smile.
Suddenly, El came to his senses and tapped his forehead. While closing his eyelids, El sighed. "I almost got lured into relying on Rinnegan!"
"I have to be careful not to be influenced by that god-level ability!" said El in a determined voice.
With a sharp gaze, El cast his eyes over the passengers, noticing how the blob of flesh had wriggled and had regenerated, again forming living tentacles.
Unlike the previous one, this time Emnu's tentacles, wriggled around his body which made every hair on El's body crawl with disgust.
"Ugh, disgusting!" complained El with an expression that showed her dislike.
"Kasumi no Kokyū." Standing calmly, the sword blade was positioned in the lower stance with a slight leaning of his body that showed readiness to move.
Straightening his back, El maintained better control over his body and was able to avoid tension.
As El tries to initiate this technique, the fog around him suddenly thickens, limiting his peripheral vision. The feet were shoulder-width apart to provide good support and ensure a stable center of gravity.
At that moment, El was about to attempt to use the Shi no kata: Iryūgiri move. However, unexpectedly like a storm coming, a rumbling sound was heard along with the Mugen carriage shaking violently.
El was suddenly knocked down, with his face hitting the floor. El fell down and very lovingly kissed the floor of the passenger carriage.
"Gyaaaah!" Just as El fell down, the sound of a death cry full of misery could be heard echoing throughout the passenger car.
At the same time, right on the roof of the train car. All of a sudden, the surface of Enmu's flesh writhed and formed an outstretched hand trying to reach the night sky, following the sound of the miserable scream.
From outside, more precisely, the locomotive part of the train derailed from its tracks. Emmu's flesh, which had joined the train, was scattered like biscuit crumbs.
As soon as the locomotive car came off the tracks and rolled violently, the other connected cars were included like an unstoppable domino chain.
In that moment, the situation happened very quickly. However, it felt like it was in slow motion for El who was flailing around on the floor of the passenger carriage, trying to hold on tightly to the passenger seat.
In addition, El could hear the horrible rumbling very clearly, as the sound of the wheels coming off the tracks was so loud as iron clashed with iron, accompanied by violent vibrations that shook the entire train.
