Hmph!

"Shinazugawa...it won't work in the light. If you don't go into the shade, it won't work." obanai said

"My apologies, master. I serve you" sanemi said

He grabbed the box and jumped onto the mansion's porch.

He stabbed the box once more

An audible girl's scream was heard

"nezuko...STOP IT!" tanjiro yelled

Tanjiro tried to stand up, but obanai forced him to the ground again.

Sanemi stabbed the box again.

Then he opened the box.

Out came nezuko.

Sanemi held his bleeding arm in front of her

"Iguro-san you're hurting him. Please ease up" shizen said

"But he keeps trying to break free, y'know?"

"Kamado, if you try to use breathing techniques while he's compressing your lungs,you'll rupture your blood vessels"

"Rupture blood vessels!? That sounds good! Cool! Do it! Rupture them!" uzui said.

"Poor, weak, pitiful child...namu amida butsu" himejima said

Nezuko stared at Sanemi's arm.

"AHHHHH!" tanjiro screamed

With that, the rope on his arms broke, and he dashed off towards the edge of the porch.

Before obanai had the chance to do anything, shizen grabbed his arm

"NEZUKO!" tanjiro called

"..."

"Hmph!" nezuko turned her head away.

"What happened?" the master asked

"The demon girl turned away Shinazugawa stabbed her 3 times, then offered his bloody arm for her to feed, but she controlled herself...and didn't bite it"one of the white haired girls said.

"In that case...nezuko has proven she won't attack people."

Obanai snatched his arm away from shizen.

"What are you doing, shizen?" he asked

"Tanjiro...nethertheless, some will still view nezuko unfavorable. Proof was needed, and now we have it. So...from now on, tanjiro and nezuko will fight for the demon slayer corps together."

Tanjiro bowed.

"Defeat one of the twelve kizuki. If you do, they will accept your words and recognize the value of your presence"

Tanjiro looked up

"I swear...NEZUKO AND I WILL DEFEAT MUZAN KIBUTSUJI! WE WILL NOT FAIL!! I'LL USE MY BLADE TO BREAK THE CHAIN OF SADNESS" he yelled

"You're not ready for that yet...for now, defeat one of the twelve kizuki"

Tanjiro turned red in embarrassment.

"Okay…"

Everyone started to stifle a laugh.

"It goes without saying that the hashira in the demon slayer corps are extremely talented. Through labourus training, they have improved themselves, defied death...and defeated members of the twelve kizuki. That's why people respect and warmly welcome the hashira. Tanjiro, you must be careful how you speak."

"Uh...okay!"

"Sanemi and obanai...do not be mean to the younger children."

"...understood."

Sanemi bowed down

"As you wish"

Head of the demon slayer corps.

Kagaya Ubuyashiki.

The rhythm of his voice and movements soothes those he addresses.

In modern terms that is called fluctuation.

It's an ability possessed by many people who are charismatic and have the strength of presence to move mass audiences.

"That is enough talk on the subject of tanjiro...you may leave. It is time for the hashira council to begin."
