Chapter 238: Special Fondness for Thunder Breathing
Marilyn's shock didn't catch Riezel's attention.
At this moment, Riezel simply watched Yuri, who looked quite upset, before suddenly reaching out to pat her on the head.
"What do you want me to say?" Riezel asked with a faint smile. "Should I brag about how amazing I am?"
His reasoning was somewhat similar to what he had said in front of Yuri when he first revealed his swordsmanship abilities after defeating the Shadow Knights with Ain and Ian.
Yuri's frustration immediately vanished as she stared at Riezel, who smiled and patted her head without warning.
It took her a moment to react.
"Don't treat me like a kid!"
Yuri quickly swatted Riezel's hand away with an annoyed look, but if one looked closely, one would notice a hint of red on her cheeks.
However, his playful gesture seemed to make her lose her mood to confront him.
"I really want to know how many secrets you're still hiding..." Yuri sighed tiredly. "If I'd known you had this level of power, I wouldn't have worried so much..."
Not responding to her words, Riezel merely smiled faintly.
What Yuri didn't know was that Riezel was actually still holding back. After all, in his match against Albert, he had used Thunder Breathing, not Sun Breathing.
Regarding this, there was a world of difference between the two.
Sun Breathing had evolved into a completely different realm, giving Riezel a stable combat power that crossed a level, making him nearly invincible even against Level 7 opponents.
Thunder Breathing, though unique, couldn't compare to the evolved Sun Breathing.
However, if that was the case, why did Riezel choose to use Thunder Breathing and not other breathing styles?
Simple.
It was simply because Riezel had a special fondness for Thunder Breathing.
In truth, not only had he mastered the five fundamental breathing styles with the help of the Ubuyashiki family, but he had also mastered the derivative breathing styles from the Hashira during their two months of training together.
Whether it was Sound Breathing, Mist Breathing, Serpent Breathing, Insect Breathing, or even Love Breathing, he had mastered these derivative styles during his training with the Hashira.
For Riezel, who had managed to grasp Flame Breathing by merely observing Kyoujurou's breathing during their first meeting in the Mugen Train, this wasn't particularly difficult. He even mastered Moon Breathing just by observing it during his battle with Kokushibou.
If this fact were known to everyone in the Demon Slayer Corps, it would surely drop a lot of jaws.
Ultimately, Riezel had nearly mastered all the breathing styles from the world of Demon Slayer, except for Flower Breathing and Beast Breathing, which he had not yet seen in person.
Among all these breathing styles, Sun Breathing was undoubtedly the most useful for him, closely followed by Wind Breathing, which could be used in Fast Attack Mode with Ariel.
While the other breathing styles didn't have as much impact because they couldn't be applied to any attack modes, Thunder Breathing was undoubtedly his favorite.
Thunder Breathing was, after all, the second most challenging breathing style after Sun Breathing and had the strongest speed and explosive power of all breathing styles, making it a preferred choice for both killing and quick strikes.
It was evident from how he developed Blooming Radiance, a new thirteenth form of Sun Breathing. Much like Thunder Breathing's first form, Thunderclap and Flash, Blooming Radiance was also an Iai technique, though they were not identical.
For this reason, he even attempted to evolve Thunder Breathing just as he had evolved Sun Breathing.
Unfortunately, he failed.
He realized that Thunder Breathing and Sun Breathing were completely different.
Flaming Thunder God, on the other hand, could achieve speeds even Upper Ranks couldn't catch, allowing Zenitsu, who wasn't even a Hashira and had none of the three abilities—the Demon Slayer Mark, the Bright Red Nichirin Sword, and the Transparent World—to decapitate his senior brother, who had become an Upper Rank.
Riezel thought these two techniques had a lot of potential and were similar in essence to his Blooming Radiance.
'Maybe if I develop them further, I might find some inspiration to improve Blooming Radiance.'
Indeed, Riezel was thinking about improving Blooming Radiance.
Meanwhile, Yuri, who was unaware of all this, was still in awe of the stunning lightning bolt Riezel had created, not realizing that it wasn't even his true strength.
However, there was one thing she did know.
"Is the swordsmanship you used a Special Swordsmanship?" Yuri asked seriously. "So, you already know and have learned a Special Swordsmanship?"
She had been trying every possible way to give this troublemaker access to her family library, only to find out he didn't need it at all.
Special Swordsmanship was, after all, something even the Frenzel family didn't possess.
"Well, I guess so..."
With such a casual answer, Riezel didn't explain much further.
In the eyes of the people of this world, Thunder Breathing could indeed be considered a type of Special Swordsmanship.
Special Swordsmanship was a form of swordsmanship that allowed a swordsman to develop unique abilities—some could summon wind, while others could control fire, performing feats similar to magic.
Since Thunder Breathing used the power of lightning, it was seen as a type of Special Swordsmanship.
However, unlike the genuine Special Swordsmanship of this world, Thunder Breathing didn't permanently enhance the body and only provided temporary effects.
For this complicated reason, Riezel didn't intend to clarify further.
"Anyway, with this, things are settled..." Riezel said calmly. "Although I can't say I'm completely safe, it should help prevent some underhanded tricks, right?"
At his words, Yuri paused for a moment before suddenly smiling.
"I can't guarantee there won't be any underhanded tricks, but I can guarantee that you'll have something to do next."
"What?" Riezel asked with a confused expression.
Perhaps out of spite, she kept him in suspense.
"You'll find out soon enough."
With that, Yuri turned and got into the carriage.
Marilyn, still shocked, gave Riezel a peculiar look before following her master into the carriage.
Still standing in place, Riezel was lost in thought.
'What did she mean by that?'
Not understanding Yuri's meaning, Riezel shook his head before getting into the carriage as well.
It wasn't until later that he realized he indeed had something to do next.
However, whether it was a good or bad thing was up to everyone's interpretation.
