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

He looked into Shinobu's eyes and smiled slightly.

"No, I treat different girls differently."

Shinobu Kocho sighed softly, her smile tinged with helplessness.

"Kawaba-kun, you know that's not what I meant."

"I will marry her."

"Why!?"

Shirakawa Yu's sudden words stunned Kocho Shinobu.

She just wanted to know Shirakawa Yu's attitude towards Kanao.

I never thought that far ahead!

"Then... Nezuko..."

“Let’s go together!” Shirakawa Yu said confidently.

"But...but now it's monogamy..."

Shinobu Kocho was genuinely taken aback, knowing that the current laws clearly stipulate monogamy.

Shirakawa Yu tilted his head.

"So, do I look like someone who follows the rules?"

Shinobu Kocho: "......"

"Alright, stop worrying about it. You don't understand dating, so don't meddle too much. When it's your turn, you can worry about it then."

Shinobu Kocho: "......"

I feel like something's off about this, but I can't quite put my finger on it.

How far are we from the Butterfly Mansion?

"Almost there, just ahead."

Bai Chuanyu was quite anxious, "Then let's speed it up! If we don't use the blood we've used up, it'll spoil!"

Chapter 89 The Three Little Ones in the Butterfly House.

The Butterfly House is a multi-purpose residence located on the mountainside.

It's very large, big enough to rival the headquarters.

This is not surprising.

After all, this is not only Shinobu Kocho's residence, but also the headquarters of the Demon Slayer Corps' logistics unit, "Kakuna".

Because of the preferences of its owner, Shinobu Kocho, the Butterfly House is decorated and built in a way that is closer to nature.

However, it has everything you need, such as training grounds, medical rooms, warehouses, and dormitories.

The Butterfly House used to be very quiet.

After all, Shinobu Kocho, the Insect Pillar, spoke softly, while her stepson Kanao simply remained silent.

If we're talking about who else in the entire Butterfly Mansion is a bit loud and boisterous, then it's only the little housekeeper, Himawari with her twin tails.

But today is different.

Before Shirakawa Yu even entered the gate, the noise erupting from the medical room gave him a headache.

"Tanjiro!!! Do you know what you're saying!?!"

The sound was sharp and urgent, like a cat whose tail had been stepped on.

"Boring???"

"You actually said it's boring?!"

"That's intensive training provided by girls!!! Intimate training!!!"

Bai Chuanyu stood at the door of the ward, his hand just touching the doorframe when he heard a rapid series of sounds coming from inside. He raised an eyebrow, not in a hurry to go in.

They will give you a massage!!!

"During training, it's okay for your hands to touch the medicine!"

"When training the ghost to grab people, it can even touch their bodies!!!"

Zenitsu's voice grew louder and louder, and the last few words were almost shouted.

Then came Tanjiro's voice, muffled and tinged with grievance.

"But... these training sessions haven't really helped me improve."

"No promotion!!? What do you mean by no promotion!!?"

Zenitsu's voice rose three octaves.

"Are you just like that pig, all muscle and all brains?!"

"This is heaven! Heaven!!!"

"All you need to do every day is be affectionate with cute girls to improve your strength!!! What more could you want!!!"

Even through the door, Shirakawa Yu could imagine Zenitsu dancing with joy.

"Look me in the eyes!"

"Tell me!!! What are you dissatisfied with!!! What gives you the right to be dissatisfied!?"

"And you!!! You stupid wild boar!!! What do you mean you can't even muster the competitive spirit to compete with someone as petite as yourself!!!"

"That's a girl!!!"

"You poor thing!!! You came from the mountains!!! You late bloomer!!! You primitive man who's never been in contact with a girl before!!!"

Zenitsu's voice was already cracking, clearly indicating that he had used all his strength.

You have no idea how wonderful girls are!!!

"Slender figure!!! Graceful posture!!!"

"As we passed by, I could smell a wonderful fragrance!!!"

"It's a feast for the eyes just to look at it!!!"

Faced with the two clueless people, Zenitsu roared and made his conclusion!

"You two are hopeless when it comes to happiness!!! You're both so stubborn and don't know what happiness is!!!"

"Tomorrow!!! Tomorrow, you two go find Miss Xiaokui and take back what you said about not wanting to train!!!"

"No!!! I'm going tonight!!!"

"No!!! Go now!!!!"

Whoosh!

The sound of the sliding door opening and closing broke the heated argument inside the room.

Or rather, it's Zenitsu's one-sided output.

"What are you doing out so late at night instead of sleeping!?"

Upon hearing this voice, Zenitsu, who had been jumping for joy and waving his arms, instantly froze.

Tanjiro's eyes lit up, and he jumped off the bed.

"Senior brother! You're here!~"

Shirakawa Yu glanced at him.

Tanjiro was wearing a hospital gown and his body was wrapped in bandages, but he was in high spirits.

"Okay. Don't jump around, or you'll cut yourself."

"Good~"

Tanjiro obediently stopped, but the smile on his face didn't disappear.

On the bed next to him, Inosuke's boar head mask was tilted towards the door.

"Hey! Brother of the Fire-Burning Boy."

His voice came from inside the hood, muffled and tinged with smugness.

"I defeated that muscular spider all by myself! Before reinforcements arrived!"

Shirakawa Yu turned to look at him.

Inosuke lay on the bed, his body wrapped in bandages, his legs dangling high in the air, looking extremely disheveled.

But the smugness in his tone was palpable even through the boar's head mask.

"I see~"

Shirakawa Yu looked at him with a smile.

"Ino is amazing~ Tanjiro has never defeated an opponent."

Piggy...so awesome...

Next to Inosuke's boar headgear, it seemed as if countless small golden suns were rising.

Although his face was not visible, everyone could hear the satisfied humming coming from his throat.

In the entire multi-person ward, only Zenitsu remained in a stiff posture.

His feet were still on Tanjiro's sickbed, his hands were still raised high in the air, and he looked as if he had been paralyzed.

"My wife is kind-hearted."

Shirakawa Yu called him by his full name.

Zenitsu instantly pulled his feet off the bed, slapped his hands against his sides, and stood up straight, like a ruler.

"Yes, Lord Oni-hashi!"

Clearly, Tanjiro had already told them about his promotion.
