It's just this name... Color Breathing?
Shirakawa Sato was stunned.
How does this name sound so improper?
It's just as improper as Nezuko's current posture, hey!
Before he could think further, the system prompts continued:
[Color Breathing: Know a Woman by Her Scent! Move the heart with emotion, control with desire.]
[Trait: Extremely strong attraction to the opposite sex. When the opposite sex is nearby, regardless of whether they are hostile, the power of the Breathing Style is greatly increased.]
[Core Rule: Analyze the other party's constitution through 'top-tier lung-passing' of the opposite sex's body fragrance.]
[Analysis levels are divided into four stages: 30%, 60%, 90%, and 100%!]
[First Stage: First Experience of Love. When analysis reaches 30%, obtain basic amplification abilities.]
[When in close contact with women, obtain an all-around improvement in physical fitness. (The stronger the target female character's overall strength, the higher the improvement limit.)]
[Second Stage: Love Stays Together. When analysis reaches 60%, obtain the 'Total Concentration Breathing: Constant' ability.]
[When within a certain range of an eligible female character (initial radius: five meters), one can automatically enter the 'Total Concentration Breathing: Constant' state without active maintenance, strengthening the body at all times.]
[Third Stage: Love's Combo Skill. When analysis reaches 90%, unlock Color Breathing forms.]
[Unlock exclusive moves for that woman. The characteristics and effects of the unlocked moves are closely related to the traits and abilities of that female character.]
[Ultimate Fourth Stage: Love's Negative Distance. When analysis reaches 100%, special rewards can be obtained.]
[Special Reward for Demons: Blood Demon Art Devourment. Can devour the Blood Demon Art of one demon (cannot devour the Twelve Kizuki).]
[Special Reward for Humans: Breathing Style Advancement. Can randomly obtain one of the three-piece set (Slayer Mark, Transparent World, Crimson Blade).]
[Bonus Newbie Gift Pack: Soul-Nurturing Nichirin Blade ×1, Basic Swordsmanship Memory Infusion ×1, Basic Physical Strengthening ×1. Accept at any time?]
[Current Character Being Analyzed: Nezuko Kamado, Demon]
[Strength Rating: C]
[Potential Rating: Extremely High (Can trigger Fourth Stage Analysis)]
[Analysis Status: 3%... 4%...]
A flood of information rushed into Shirakawa Sato's mind, making his head spin, yet he grasped the core idea instantly!
Breathing Style! The system was generated based on his Breathing Style!
Although the name was strange, the effects... seemed ridiculously powerful!
Getting stronger just by being close to girls!
Constant Breathing Style without even training—and with increased efficiency!
The "forms" of the Breathing Style could also be automatically acquired through long-term contact with girls?
Even... even after completely winning over a girl, there were special rewards.
Devouring Blood Demon Arts! The combat power three-piece set!
(✧ω✧)
Th-this, this... wasn't this tailor-made for him?
And since it ignored friend or foe, did that mean he had an innate advantage when dealing with the opposite sex?
Tsk... if Muzan were to cross-dress, would there be a bonus too~?
Of course, that was something to think about later.
Right now!
The most, most, most important thing was—
Nezuko... was right in his arms!!!
Small, soft, warm, fragrant, and... holding onto him so tightly...
Especially her smooth little face, rubbing against his neck from time to time, her hair occasionally brushing against his cheek.
That silky, tingling sensation...
Could this be heaven!?
Shirakawa Sato snorted twice, as if even his breath had turned light and giddy.
"Mmuh?!" Nezuko, pressed against him, seemed to notice the change as well...
Her movements paused, and she lifted her small face, her pink eyes looking at him in confusion.
She felt that the temperature of this "big meal" beneath her... seemed to be rising?
And within that tempting scent, there was now something extra that made her feel... very comfortable, very at ease.
It wasn't the scent of food, but more like... the warmth she used to feel when leaning into her mother's arms or holding her brother's hand.
Nezuko's hunger... faded quite a bit, replaced by a deep sense of attachment.
The basic trait of Color Breathing—Attraction to the Opposite Sex—activated!
Feeling the change in the girl's movements, Shirakawa Sato turned his head and met Nezuko's close, innocent, and curious pink eyes.
His heart pounded wildly.
This was a living, breathing, soft Nezuko!
Even as a demon, she was still overwhelmingly cute!
And it was because of her that he had awakened this strange Breathing Style...
"Th-thank you..." Shirakawa Sato muttered subconsciously, his face turning even redder.
Nezuko: "???" (tilts head)
"Shi—ra—ka—wa—Sa—to—!"
A low growl, squeezed out from clenched teeth, snapped Shirakawa Sato out of his (self-imagined) dreamy state.
He stiffly shifted his gaze and saw Sakonji Urokodaki not far away, radiating a terrifyingly oppressive aura.
"Now that you're awake, let her go!" Sakonji Urokodaki said word by word, each one as cold as ice.
"You brat, pick a better time to be a pervert! Aren't you afraid she'll bite through that bamboo and take a chunk out of you?! She's a demon! Just turned!! And she's starving!!!"
The last sentence was practically shouted.
"M-Master..." Shirakawa Sato shuddered, his survival instincts instantly overriding his reluctance to release the warm, soft figure in his arms.
Even so... holding Nezuko felt far too comfortable.
Petite but not fragile, carrying the soft warmth unique to a young girl.
The fabric of her pink kimono felt gentle against his body.
And that scent lingering at the tip of his nose—a sweet, floral, youthful fragrance—made his head feel light, almost dizzy.
But... his life was more important! Explaining was more important!
Shirakawa Sato forced what he thought was an innocent smile onto his face, his hands subconsciously loosening as he tried to push Nezuko away slightly.
[Warning! Zero-distance contact state is about to end! The analysis rate for target 'Nezuko Kamado (Demon)' will drop significantly!]
[Current analysis rate: 3% per minute. After zero-distance contact ends, it will drop to 0.03% per minute.]
The system notification rang out coldly in his mind.
What?!
After separating, the analysis rate drops a hundredfold?!
Holding her, it would only take half an hour to reach 90%.
Not holding her, it would take three days?!
How could that be?! His Breathing Style! His path to strength! His benefits—(no, forget that)!
The already hesitant Shirakawa Sato immediately made his decision.
Even if I die, I won't let go!
His arms suddenly tightened, and the distance he had just created vanished instantly.
Not only did he pull the confused Nezuko back into his arms, but the force of it made their bodies bump together with a soft thud.
"Mmuh!" Nezuko let out a small cry, her bamboo muzzle tilting slightly.
But she didn't seem to dislike it.
Instead, being pressed tightly against that comforting and enticing scent again made her pink eyes narrow in contentment.
Her small face instinctively rubbed against his neck, and a soft, cat-like purring sound escaped her throat.
[Zero-distance contact restored. Deep analysis rate resumed. Current analysis rate: 3% per minute.]
Phew—that's better!
A relieved, slightly silly smile spread across Shirakawa Sato's face.
Ah, this efficiency, this boost, this intoxicating softness...
However, in the eyes of the others, that smile looked completely different!
From Tanjiro's perspective: this stranger had clearly loosened his grip just now, yet suddenly grabbed his soft, gentle, cute, and innocent sister again—and even tighter than before!
And that expression on his face... that shameless, irritating grin!
This, this, this... was outright provocation!
A direct insult to him as Tanjiro Kamado, her older brother!
"You bastard!!! Let go of my sister right now!!" (ﾒ｀ﾛ´)/
