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

It seems like she was trying to act cute, but maybe she thought of something else.

Suddenly she shivered and changed back to her original state with a look of disgust.

Until he reappeared in his original form.

Everyone breathed a sigh of relief.

But Shirakawa Yu had no intention of stopping.

"Kawayu, stop playing now—"

Tamayo tried to step forward, but he stopped her with a gesture.

"Wait a minute!"

As he spoke, he suddenly hunched over, looking constipated.

"I need to make some adjustments."

"Adjustment?"

Tamayo didn't understand.

No one at the scene knew what his so-called adjustments were.

But they soon found out.

Suddenly, without warning, a lump appeared on Shirakawa Yu's hunched back, like a huge tumor.

The tumor is getting bigger and more active.

It was as if something was wriggling inside, trying to break free.

Shinobu looked worried, and Kanao covered her mouth.

Less than two seconds later, there was a loud "bang!"

The tumor ruptured.

In an instant, a gust of wind swept across the entire arena.

The torches crackled and sputtered, dust billowed up, and flying pebbles splashed ripples in the pool of blood that Muzan had spat out.

As everyone squinted and re-examined the central altar,

The enormous black and red shadow sent a chill down their spines.

That is...?

wing!??

That's right.

At this moment, Shirakawa Yu stood still, gently stroking the enormous wings that stretched out from behind him, formed by bones, muscles, tendons, and membranes.

They were a pair, like bats, with black and red wings.

"That's more like it."

Shirakawa Yu nodded in satisfaction.

The next second, the wings flapped suddenly.

As the wind howled once more, Shirakawa Yu, like a sharp sword, shot straight towards the heavens.

"Wow~~~!"

Joyful sounds, accompanied by the sound of the wind, rang out freely in the sky.

The crowd below stared, mouths agape, heads tilted back, all frozen in place for a moment.

Can you do this?

Immediately afterwards, they all looked at Muzan, who was equally dumbfounded.

It can be... like this?

When Muzan saw Shirakawa Yu's free and unrestrained figure, moving like the wind.

There was only one thought in his mind.

These years...

What have I been doing?!

Flying has always been an eternal dream of humankind.

At this moment, almost everyone below has experienced it.

Flight powered by crimson arrows.

Only Shirakawa Yu has never had his feet leave the ground for more than ten seconds in his entire life.

play!

疯！

fly!

He was overjoyed.

"This is so awesome! Hahaha~~~~"

Seeing Bai Chuanyu's childlike behavior, most of the girls below smiled like doting aunts.

A small number of them were also eager to try.

I want to go up to the sky for a spin.

Before they could even ask for a hug...

Shirakawa Yu above had already fallen like a cannonball.

He landed back on the altar, but his brow was furrowed.

"I feel like it's still lacking something."

So... he closed his eyes.

No one bothered him; they all wanted to see what new ideas or changes he might have.

However, they did not realize that this change did not originate from Shirakawa Yu himself.

Rather, it comes from their surroundings.

To be precise, it was the...eyeballs around them.

Chapter 348 The Changes Brought About by Muzan's Blood Demon Art.

The moment Shirakawa Yu's consciousness fully connected to his eyes.

The shimmering blue speed patterns that were originally attached to the eyeballs gradually disappeared, and the arrowhead of the Crimson Arrow slowly changed from its somewhat aggressive arrow shape to a normal appearance.

It was still golden, but it had lost its previous eerie aura and looked more like it was alive.

More like, his own eyes.

The change in his eyes attracted everyone's attention.

And this is not the end.

Compared to what happened next, the previous changes were merely minor alterations.

Under the increasingly horrified gazes of the crowd.

The tentacles beneath the eyeballs gradually grew thicker and larger, eventually transforming into... wings.

It has one big eyeball and two wings; it looks bizarre no matter how you look at it.

it's fine.

Because very quickly, these eyeballs collided and merged together in pairs.

Then, they grew heads.

It grew a body.

Claws grew, feet grew...

Thousands upon thousands of tiny creatures flapped their newly grown wings, their movements clumsy and unsteady.

Under everyone's astonished gaze, it slowly rose into the air, danced, and converged.

A huge, orderly, dark vortex formed in the air above Shirakawa Yu's head!

"Bat...bat!?"

The voice came from Muzan's mouth.

Bai Chuanyu was having so much fun that he didn't care about Muzan, who was practically useless.

And now they are no longer bound by the Crimson Arrow.

He lay helplessly on the ground, his head tilted back.

Looking at the terrifying scene in the sky that resembled a natural disaster.

He didn't run away, he didn't attack, he just... stared blankly...

Muttering blankly...

"He turned... Nakime's eyeballs into... flying bats...?"

As the bats became more and more skilled at flying, their speed increased.

The bright blue speed stripes have disappeared.

But that doesn't mean it disappeared at lightning speed.

Just like the Crimson Arrow, it has simply become the norm.

It didn't disappear.

The bats flew faster and faster, until they were no longer visible, and they completely transformed into a black storm.

Shirakawa Yu also rose up, flapping his wings and soaring straight into the center of the terrifying storm.
