Chapter 100

【Wish myself a happy birthday.】

"What's going on?"

Inside the Infinity Castle, Muzan suddenly felt that an evil demon had lost contact, and he couldn't feel any aura at all.

Although Muzan didn't care at all about ordinary evil demons.

But, if he discovered an anomaly, he would absolutely not hesitate to catch them and destroy them with his own hands.

Not only that, but he hadn't even had time to check what was going on before he had already lost the connection.

And, because the distance was too far, he hadn't been able to sense much.

"Could it be that another one, like that cheap woman Tamayo, has escaped my control?!"

"Damn it! Bastard!!"

Over the years, Muzan hadn't had anything go his way no matter what he did.

Not only had he failed to find the Blue Spider Lily, but he hadn't even been able to find the traces of the Ubuyashiki clan to annihilate them!

And the variable that caused all of this had to start from that white-haired demon hunter that Doma encountered three years ago!

"It must be that white-haired demon hunter causing trouble again! What a damn guy!"

(Zero: I cause trouble, but I don't cause demons.)

In a fit of rage, he smashed everything in his study to vent the dissatisfaction in his heart.

"When it comes down to it, this is all the mistake made by that guy Doma! If it weren't for him failing to finish off that female Hashira earlier three years ago, how could things like this happen now!"

Thinking of this, Muzan was even more furious.

He called out to Nakime in his mind.

"Nakime, bring Doma to me!"

Twang!

With a sound of the biwa, Doma appeared in Muzan's study, still holding a female limb in his hand.

"Oh my, Lord Muzan, I wonder what you have summoned me for?" Doma asked with a grin.

Muzan didn't speak, just slapped him across the face.........

Demon Slayer Corps Headquarters.

After Zero returned to the Demon Slayer Corps Headquarters, the first thing he did was find Tanjiro.

And he prepared to tell him the news that Nezuko could turn back into a human, so that their family could reunite properly.

But when Zero found Tanjiro, he discovered him sitting in the backyard of the Butterfly Mansion, looking at the sky with a look of despair.

He was holding several letters in his hand, and the three little ones of the Butterfly Mansion were constantly comforting him around him.

"Kiyo, Sumi, Naho, Tanjiro, what... what happened to him?"

"Lord Zero Hashira!" x3

Seeing Zero, the three little ones of the Butterfly Mansion couldn't help but exclaim, rushing forward to surround and hug Zero.

Kiyo: "Tanjiro is troubled because of the sword."

Sumi: "Mr. Haganezuka sent a letter saying he doesn't want to break swords for Tanjiro anymore."

Naho: "Tanjiro is trying to find a way to apologize to Mr. Haganezuka."

"I see..." Listening to the answer from the three little ones of the Butterfly Mansion, Zero fell into deep thought.

Subsequently, he stepped forward and picked up the letters in Tanjiro's hand to take a look.

【No more swords for you! Unforgivable!】

【Don't even think about getting a sword from me!!】

【I will kill you! Curse you to death!】

Although it was just a few short sentences, one could still see the full resentment of Hotaru Haganezuka branded on the letters.

As well as that resentment full of killing intent!

As if it had turned into a disaster-level cursed spirit, ready to take Tanjiro's life at any time...

"Big Brother Zero, what should I do... without a sword, I can't go out to carry out missions..."

"I'm really sorry to Mr. Haganezuka for breaking the sword he forged for me every time... It's over... It's over now..."

Tanjiro didn't know how to express his current mood.

Seeing this, Zero just sighed slightly and said: "You don't have to think too much, for this period of time, just train properly according to the method I taught you before.

Haganezuka also just has a sharp tongue but a soft heart; maybe when the time comes, he will send the sword to you."

"Really?"

"Probably... well, let's not talk about this, I have some good news to tell you."

"What good news?"

"Do you remember what Tamayo once said?"

"I remember, Tamayo said back then that demons could turn back into humans... Big Brother Zero, do you mean that Nezuko can now..."

"Yes, little sister Nezuko can now turn back into a human."

"Really?! That's truly great!"

Hearing the news that Nezuko could finally turn back into a human, the previous troubles were swept away in an instant.

Nezuko turning back into a human meant she could reunite with her family properly, and no longer had to run around with him every day.

"Without delay, let's go to my residence now, let little sister Nezuko turn back into a human, and reunite properly with your family."

"Mmm! Thank you, Big Brother Zero!"

"You're welcome, this was also my original promise."

After saying goodbye to the three little ones of the Butterfly Mansion, Tanjiro couldn't wait to return to Zero's residence.

He arrived at Zero's room.

Xiao Yue was playing with Nezuko.

The curtains in the room were drawn, and only the lights were on, clearly to prevent Nezuko from seeing the sunlight.

Seeing Zero and Tanjiro, Nezuko pounced over.

"Nezuko!" Seeing this, Tanjiro was just about to catch Nezuko, but didn't expect Nezuko to pounce directly into Zero's arms.

"Uh..." Tanjiro felt a bit heartbroken; didn't Nezuko see him?

Or was it that her brother was no longer important.

He had the feeling of the cabbage at home being arched by a pig.

But, thinking about it carefully, Zero didn't seem to be a pig, and it didn't seem impossible for him to be his brother-in-law.

It was just that what Tanjiro saw in Zero's eyes was that he only treated Nezuko like a younger sister.

There was no romantic feeling mixed in at all.

"Master, you're back~"

"Mmm, thank you for your hard work, Xiao Yue, where are Kanae and Mitsuri?"

"Kanae and Mitsuri said they were preparing some clothes, I don't know the specifics, and they also said they wanted to prepare a surprise for you."

"A surprise?"

Although they said it was a surprise, Zero always felt that this didn't seem like a surprise, but rather more like a shock...

"I must be overthinking it, they should be preparing clothes for themselves... right..." Zero thought to himself.

Subsequently, he put down little Nezuko in his arms and took out a vial of medicine.

"Tanjiro, this is the medicine sent by Tamayo; I've already experimented with it, and it can indeed turn a demon back into a human.

But, just in case, I still have to tell you in advance; no matter what I'm about to do, don't stop me, so..."

"Big Brother Zero, I trust you!"

Before the words were finished, Tanjiro interrupted what Zero was about to say.

He understood that Zero was also doing this for Nezuko's sake, and now that he had told him personally, it showed that he was also thinking of Nezuko and everyone.

So he chose to trust Zero; he didn't smell the scent of lying on Zero.

"Mmm, as long as you understand."

Subsequently, he removed the small muzzle from Nezuko's mouth.

Nezuko, with the muzzle removed, revealed those two sharp demon fangs, and combined with her dazed and cute appearance, she was truly adorable.

"Come, Nezuko, open your mouth, ah~"

Zero was like an older brother coaxing a little girl to take medicine, letting Nezuko open her mouth and feeding her the medicine.

Although Nezuko didn't quite understand, she still obediently opened her mouth, waiting for Zero to feed her.

Subsequently, Zero slowly poured the medicine in the test tube into Nezuko's mouth.

When Nezuko had drunk all the medicine, Tanjiro didn't feel any change in Nezuko either.

However, not long after, Nezuko suddenly curled up her body and struggled on the ground.

Cold sweat kept pouring out from her forehead.

She appeared to be in great pain.

"Big Brother Zero, what is going on?"

"I don't know either, I clearly experimented with it before!"

Zero immediately stepped forward to help Nezuko up and hold her in his arms, comforting her: "It's okay, Nezuko, we're all here! Don't be afraid~"

Perhaps the comfort had an effect, and Nezuko calmed down a little.

But one could still see the painful expression on her face.

One hand tightly grabbed the collar of Zero's clothes, and Zero also grabbed Nezuko's hand, comforting her the whole time.

Seeing this, Tanjiro reached out and grabbed Nezuko's other hand.

Kie Kamado heard the commotion downstairs and came upstairs to check.

"Th-this is..."

"Mother, Nezuko is turning back into a human, but she... seems to be in great pain..."

Seeing this, Kie Kamado also came before Nezuko, reaching out a hand to stroke Nezuko's little face.

"Nezuko, hang in there! We're all here!"

"Sister!"

Takeo and the others also appeared at the door, running in together, forming a circle, and kept cheering for Nezuko.

At this very moment, Nezuko's eyes were still somewhat unfocused, clearly her self-consciousness hadn't recovered yet, and she had been struggling!

"Maybe I can try!" Zero remembered that Nezuko seemed to like listening to him sing, so he started singing that song from his vague memory again.

The sunset on the sea is like a young painting?

Spreading across the sky waiting for the seagulls to carry it away?

The distant sails let the wind and waves beat?

Not afraid even if it hurts for the dream?

The drifting wind and sand go to whose horizon?

Has the spring breeze ever seen him anywhere?......

The comfort of the singing voice made Nezuko gradually calm down, and the painful expression on her face slowly faded away.

However, Tanjiro and his family saw a tear appear in the corner of Zero's eye, sliding down his cheek and dripping onto Nezuko's forehead.

"Such a sad, such a vicissitudinous taste... what has Big Brother Zero experienced? Why does it feel so sad..."

Tanjiro smelled a scent emanating from Zero that was out of the ordinary, as if he had experienced all kinds of difficult things.

More of it was... life and death separations.

He couldn't understand why this scent would appear on Zero?

Kie Kamado didn't understand the language of this song, but in her heart, she felt sad for Zero.

Only Xiao Yue knew what was going on......

Ever since Xiao Yue (T0) was created, she often saw Zero staying in his room alone, singing this song.

Later, Luo Li told Xiao Yue (T0) that this was a well-known song that Zero (Bai Yue)'s mother often sang to him to coax him to sleep when he was very young.

Later, this song seemed to be branded in Zero's memory; he only knew that this song was sung to him by someone he was very familiar with.

But he couldn't remember the past events of his childhood...

A moment later.

A small hand climbed onto Zero's cheek, wiping away the tears on his face for him.

"Zero... brother..."

"Nezuko? You... you've recovered?!"

"I... remembered everything..." At this moment, Nezuko remembered everything.

During the period of struggling in her consciousness, she recalled every single thing.

She remembered holding Rokuta's little hand when she was a child, playing in the ice and snow...

She remembered every day her family accompanied her...

She remembered the few happy days after meeting Zero for the first time...

She remembered a monster she had never seen before suddenly breaking into their home at night to hurt her family...

She remembered Mr. Tomioka, Mr. Urokodaki, Tamayo, Yushiro...

She remembered the smiles of everyone she met in the Demon Slayer Corps...

Fragmented memories appeared in her mind like a revolving lantern, allowing her to find her self-consciousness.

She also remembered that when she became a demon, Tanjiro had told her that no matter what, he would protect her.

Until she turned back into a human and reunited with her family again.

【I am... Kamado Nezuko...】

【Family... almost killed by a demon...】

【Big Brother Zero... saved my family...】

【I still want to... continue living with my family...】

Plus hearing Zero singing this song just now, it allowed all the memories in her mind to be pieced together.

The light and self-consciousness returned to her eyes.

"Zero brother... you cried... this is the first time I've seen you cry... don't cry..." Nezuko comforted him in Zero's arms.

Zero smiled and said: "I'm fine, it's great that you've recovered; your family has been waiting for you."

"Nezuko, my child!!"

Kie Kamado couldn't hold back anymore, hugging Nezuko into her arms, tears streaming down her face.

"It's truly great, Nezuko!"

"Sister!"

Tanjiro and his younger brothers and sisters hugged their mother and Nezuko together, shedding happy tears!

Zero and Xiao Yue looked at each other and smiled; seeing that their family was finally reunited completely, they were also happy for them.

Coming to the backyard, Nezuko slowly extended a hand, gradually appearing under the sunlight.

Seeing that there was no burning sensation on her hand, she then slowly took a small step.

Finally, her whole body was exposed to the sunlight.

Feeling this warm sunlight after a long time, Nezuko closed her eyes, bathing in the warm sun.

A sweet smile remained on her face the whole time.

"Nezuko, how do you feel?"

"Zero brother!"

Seeing Zero appear behind her, Nezuko pounced into his arms again, hanging on his neck, just like her habit before she turned back into a human.

"You, you, have you forgotten that you're not a demon now?"

"Ya!!! So... sorry Zero brother, I... I..." Nezuko was somewhat embarrassed; she had almost forgotten about this.

Now that she had turned back into a human, she still thought it was the same as before, not yet turned back, and was somewhat unaccustomed to it.

"Alright, alright, I'm not blaming you, you also need to be careful; you're a girl, if you're seen by others, you won't be able to get married~" Zero teased.

"If I can't get married, I'll marry you..." Nezuko lowered her head, whispering to herself in a small voice.

"What did you say?"

"No... nothing, Zero brother, you heard wrong~"

Nezuko covered her face shyly, not daring to look at Zero anymore, and quickly rushed into the house.

"Huh? What happened? Did I say something wrong?" Zero looked puzzled.

He even thought for a moment that there was some strange smell on him, which was why he had scared Nezuko away.

He smelled himself to see if there was any strange smell, but after smelling for a long time, he didn't smell any strange smell...

Xiao Yue, hiding in a corner somewhere, saw this scene and couldn't help but complain in her heart: "Master is really a blockhead! So stupid! After returning to the Starry Sky, I must tell all of this to Luo Li sister! Hehehehe~"

Zero, who was still looking for problems on himself in the backyard, couldn't help but feel a chill...

That night.

Kie Kamado cooked, making a rich dinner, and enjoyed it with everyone.

Nezuko also experienced the happy days of truly reuniting with her family after a long time.

Happy tears flowed sparklingly.
