Demon Slayer: My breathing technique went awry after Nezuko pushed me down.

Muzan, who ate people his whole life, would be quite a sight to behold if he were to be eaten by someone in the end.

Of course, even if it were feasible, my own capabilities would still be far from sufficient.

Instead of thinking about how to devour Muzan, we should first think about what kind of Blood Demon Art could kill Muzan.

It's still the kind of way of keeping his bottom out of the sun, lest he turn to ashes and become inedible.

And in order to achieve this goal.

The fourth tier of rewards for human females.

Therefore, the three-piece combat power set has become of paramount importance.

Without the Transparent World, one cannot strike Muzan's vital points, nor can one slice Muzan along the dotted lines.

Without the Crimson Blade, even if you strike Muzan's vital points, it's useless; he can heal in a second.

Only that mark...

To put it bluntly, it's about forcibly stimulating a lethal dose of adrenaline.

If you open it, you won't live past twenty-five.

To be honest, Shirakawa Yu didn't want this thing at all.

After all, the system said that it activated the markings, not the natural markings.

He didn't want to die young at the age of twenty-five just to kill Muzan.

What's the point? What gives them the right?

He had no intention of sacrificing his life to selflessly protect this land.

But the rewards for the three-piece set are random.

According to Murphy's Law, unless he doesn't want any of the three pieces, he'll only ever be a 'Ghost Knight' for the rest of his life.

Otherwise, the first thing you might see is a pattern.

Even though I was incredibly lucky, I didn't get the pattern on either of my two attempts.

But before the final battle in Infinite City, someone will always open it.

As long as I don't hide, I'll get infected eventually.

Therefore, after much thought...

Shirakawa Yu still felt that he needed to have a backup plan.

To grow scars and survive... currently, aside from Yoriichi Tsugikuni who was born with scars.

Only one person did it—

Yoriichi Tsugikuni's older brother, Kokushikatsu Tsugikuni!

Or rather, the first of the twelve Ghost Months.

Upper Moon One, Kokushibo!

Refer to his path of surviving even after activating his markings.

That's right!

Shirakawa Yu's backup plan is...

Turn into a ghost!

Of course, the ghost he wants to become isn't the kind that's grotesque, dies in the light, and has to eat people.

Those inferior demons not only lose their memories and become psychologically twisted, but they are also at risk of being destroyed by Muzan's "minion dematerializer" at any time.

Shirakawa Yu had no interest in that kind of ghost.

He wanted to become like Miss Tamayo.

They are indistinguishable from ordinary people in appearance, but they have escaped Muzan's control and can survive simply by drinking blood.

Such a life form, rather than being a ghost...

Shirakawa Yu prefers to call them—Vampires!

When asked about becoming a ghost, Shirakawa Yu felt resistance.

But vampires are the complete opposite.

Shirakawa Yu is willing to open her arms wide and, with utmost enthusiasm, become a top predator in the food chain.

Of course, this is on the premise that the problem of 'sunbathing = death' can be solved.

He didn't want to leave himself with such a big opening.

The key to this problem lies in the sleeping little girl in front of us...

Nezuko!

There are many speculations about why Nezuko was not afraid of sunlight after she became a demon in her previous life.

The most widespread one is that Nezuko's house has blue spider lilies.

The Kamado family ate the Flower of Wishes that Muzan had been searching for for hundreds of years as wild vegetables, which is why they were able to become 'Daywalking Demons'.

However, the official statement later clarified that the blue spider lily only blooms for two or three days a year, and each time it blooms during the day and for a very short time.

Tanjiro only met his mother once by chance when he accompanied her to sweep her grave.

Therefore, whether Nezuko's fearlessness of the sun is related to the blue spider lily is still unknown.

Some say that the Kamado family has always passed down the Breath of the Sun as a form of Kagura dance.

This altered their genes, allowing the Kitchen Brothers and Sisters to remain unafraid of sunlight even after they became ghosts.

There is also a more idealistic interpretation.

Because Nezuko has never drunk blood, her power comes entirely from protecting, not from plundering, and she even needs to sleep to recover.

This may be why the sunlight was unwilling to kill her.

But regardless of which one it is, Shirakawa Yu is unsure and naturally doesn't want to take any risks.

Feeding Nezuko blood can indeed help her wake up sooner and establish a connection with herself.

However, there is also a slight possibility that Nezuko, having tasted blood, might lose the opportunity to become a daytime demon.

Rather than taking a gamble to keep Nezuko by your side two years earlier.

He still felt that Nezuko should be allowed to develop according to her own opportunities.

At least the general direction cannot change.

This will become the key for him to obtain the perfect vampire bloodline in the future.

If we can truly achieve our goal.

future......

With his power, he could easily reshape or even control the country according to his own preferences.

Create your own paradise!

After making the decision, Shirakawa Yu breathed a sigh of relief.

While gently rubbing Nezuko's adorable, chubby face, he cheerfully told the system, "Retrieve newbie rewards!"

The next second, a memory surged into his mind, and a jet-black longsword suddenly appeared in his hand.

Feeling the basic sword techniques becoming clearer in his mind, Shirakawa Yu drew the Soul Nourishing Sun Blade, a reward from the system, with unparalleled skill.

A flurry of knife flashes passed by.

Nothing had changed around them except for three neatly arranged, evenly distributed strands of hair on the blade.

Shirakawa Yu's eyes were full of satisfaction.

Basic knife skills, really basic.

There are no fancy tricks, just the simplest control of the knife.

He has no set moves or techniques, yet he can control the knife with the precision of a finger.

As for this knife...

It is not a common samurai sword.

Although they look similar, those familiar with knives can tell the difference at a glance.

The blade and body of a samurai sword are both curved, making them suitable for slashing but not for thrusting.

The blade in Shirakawa Yu's hand had a straight spine like a pine tree, extending all the way to the tip without any curve.

Tang Hengdao!

The ancestor of the samurai sword!

The straight blade allows the Tang Hengdao to be used for both slashing and piercing, and its thicker spine compared to a samurai sword also makes it effective for chopping enemies with strong defenses.

Of course, to be fair, for the current level of demon slaying, a flat-bladed katana that emphasizes slicing is more suitable for decapitating demons.

However, the katana also has a fatal weakness.

To maximize cutting power, his blade is often cut very deep, resulting in a thin spine that is sharp but easily broken, snapped, or chipped.

This explains why, in the show, it can often behead a vulnerable enemy with a single blow.

However, when encountering enemies with high defense, a single strike will force the Demon Slayer Corps members to fight with broken swords.

The Tang Hengdao, on the other hand, does not have this drawback. With its shallow blade and thick spine, it rarely has the chance of breaking.

That alone is enough to make Tanjiro, who only has one sword per season, drool with envy.

It can also prevent top-tier vengeful spirits from having a chance to exert their power.

Of course, whether it breaks or not is not the point.

Anyway, the system said that the specially customized knife will not break or wear out.

Shirakawa Yu mainly liked its appearance.

Handsome!
