When Tanjiro woke back up, he immediately caught the voice ushering his sister to wake up, he let out a groan as he propped himself into an upright sitting position, when he opened his eyes he noticed the many… Unique looking people, recognizing Shinobu among them, all of which were looking at him. Right. At. Him.
If he had stagefright, this would've probably knocked him out cold again, but instead he silently stared back at them.

"Hm! Looks like he's finally woken up!" A man that looked like he was on fire said.
Flame Hashira, Rengoku Kyojuro.

"Let's skip the trial, I'll cut off his head with style and give you the most flamboyant blood splatter you've ever seen. The sister will follow soon after." A large-built man with a head-wrap and facial tattoos said.
Sound Hashira, Uzui Tengen.

"Eeeeh? Kill such cute siblings? It pains my heart just thinking about it…" A woman with a rather unique hair coloring thought, the way she felt plastered on her face.
Love Hashira, Kanroji Mitsuri.

"Ah… What pitiful children, how sad. It's a tragedy they were even born." Another large-built man said, this one adorned with prayer beads, and appeared to be crying while praying.
Stone Hashira, Himejima Gyomei.

The last one that caught Tanjiro's attention was a boy around his age, looking up at the clouds likely not even paying attention, his appearance made wavy by his outfit and long hair.
Mist Hashira, Tokito Muichiro.

"Let's kill 'em!" The fiery man said again, "Yeah, but with style!" The head-wrap guy responded right after.

"...A… A trial…?" Tanjiro thought, his eyes then locked on his sister's body which was still lying motionless on the ground with her hands tied, a Kakushi hovering over her giving the appearance he tried to wake her up.
Tanjiro soon realized he too was tied up, although he didn't have rope, but sturdy cuffs, cuffs that clanked with every movement he attempted to make.
His gaze returned to the people still discussing how to kill him before he saw her sister stir, then wake up, "Nezuko! A-Are you... O-Okay!?" he cried out, he wanted to leap from the patio and come to his sister's aid, but he decided to be smart and remain where he sat, shaded from the sun at the back of a patio and under strict gaze of the Hashira, a single wrong move, and he'd be dead.

"Onii-chan?" Nezuko said under her breath as she looked up, she quickly noticed her brother staring back at her with terrified eyes, cuffed where he was sitting, she herself jolted upright, only to fall on her behind thanks to her tied-up legs.

"She must have no idea what's going on, going as far as to travel with her turned Brother, I pity these children." Gyomei said, drawing Nezuko's attention, she turned her head to face the source of the man's voice which allowed her to see the other people standing there, staring at her.
If there was a time to be scared, now was it, first they beat the Lower Moon 5, but likely, now they had to prove themselves to the corps, "...This… This is what Urokodaki warned us about, right?" she thought as her eyes scanned the line of people.

"Can we hurry up? I don't want to look at that wretch any longer." A new voice called out, both Kamados immediately perked up to look at the source, a man with a bandaged jaw, wearing a striped haori and having a live snake loosely around his neck.
He was pointing right back at Tanjiro, which only amplified his feelings of uneasiness.
Serpent Hashira, Iguro Obanai.

"Iguro is as cool as a snake as ever…" Mitsuri said to herself as she stared at the man, adoration clear in her eyes.

"Before we actually settle on anything, shall we question the girl first?" Shinobu asked with her ever present smile, drawing everyone's attention to her while she herself drew her attention to Nezuko, "Do you have anything you want to say first?" she asked, "Like why you travel with a Demon, for example?"
Insect Hashira, Kocho Shinobu.

"He's… He's my o-older-'' was all Nezuko's dry throat could give before she erupted in a coughing fit, considering her latest experiences she could probably use something to drink, which is exactly what Shinobu offered, "Here, have some water." she said as she pulled out a Gourd, she walked up to Nezuko who steadied herself and shuffled to face the Hashira, Shinobu helped her take the first few gulps before the Gourd was emptied entirely into Nezuko's throat who let out a content sigh after, Shinobu put the cork back on the Gourd before returning to the line, "Now then, go ahead and tell us.

"He's my Older Brother..." Nezuko began, "I became a Demon Slayer so I could avenge him, but on the way found someone that says they'll work on a cure to turn him back into a human! He hasn't hurt anyone, he doesn't want to hurt anyone, he's still just as human as we are, maybe not physically but mentally…"

"Stop spewing such nonsense. I don't trust anything anyone says, and I especially do not trust you. He's your brother, of course you'll protect him." Obanai said, his finger still firmly pointing at Tanjiro, Gyomei soon chimed in, "Ah… she's possessed by a Demon, hurry up and kill this child to set her free."

"P-Please! Hear me out, it's been two years since he became a Demon, he controls himself, he… He even already tasted human blood, but he's still by my side..." Nezuko pleaded, hesitation crept up her face as she turned to share a look with Tanjiro, who still looked terrified, "He feels bad enough about himself as is, he's too kind to hurt anyone."

"This conversation is just spinning in circles." Tengen said sturdily, "He hasn't hurt anyone you say? And now you say he's tasted human blood? What proof do we have that he won't hunt and eat someone the moment we let him go? Show me! Impress me!"

"U-Uhm… I'm not so sure about this…" Mitsuri suddenly said, "The Master of the Mansion probably knows about this already, and I don't want to act without his direct consent… Should we wait until he arrives?", With those few sentences most gazes were immediately on her.

Through all of this, Nezuko felt her gut turn, and so she pleaded again, "N-No! My Brother fought by my side, you… You can ask Kocho, or Tomioka!"

However, before any asking could take place, a new voice chimed into the conversation, filled with interest and with an undertone of malice, "Say… This is getting rather interesting!" they said.
All eyes were on him, approaching was another Hashira, his body ridden with scars and his eyes made him look insane.
Wind Hashira, Shinazugawa Sanemi.

"He has even more scars than before, how rugged!" Mitsuri thought to herself as she gazed upon Sanemi's exposed chest.

"What's that you say about that demon, you brat? He can fight alongside you? Like a Demon Slayer that protects humans? Do you know what we call that?" Sanemi asked, he let the question sink in for a moment, there was an eerie silence before he answered his own question, "A total delusion, you moron!"

"No bickering, the master arrives soon." Giyu suddenly said, standing alone near the edge of the garden.
Water Hashira, Tomioka Giyu.

In an instant, everyone calmed down and the Hashira's eyes were firmly pinned on the door into the mansion, a few moments later the sliding doors opened and two identical twins walked out, Nezuko recognized one… of them? From Final Selection, "The Master of the Mansion has arrived." one of them spoke out, and soon after the man exited through the doors, while his attire caught no one's attention, what did catch the Kamado's attention was the man's face, wrinkled and discolored like a disease, "Is he… ill?" Nezuko thought, and a similar thought went through Tanjiro's head.
The man was soon guided by the children, sitting down near the edge of the patio, "Good morning everyone. It feels like a beautiful day, the sky is a clear blue isn't it?" he began, his voice sounded so… soothing, like a melody that put the Kamados at ease immediately, it was unnatural, "I'm glad we can have our twice-yearly Hashira Meeting without any members having changed."

"H-He's the Master of the Mansion…? But he's definitely ill…" Nezuko thought before she was suddenly forced to turn around and her head was shoved downwards like a forced bow by Sanemi.
The other Hashira bowed by themselves, Sanemi included after his brutish action, all of them in a singular row.
The Kamados were impressed and shocked to say the least, this man managed to gain the respect of each of them, how is something they probably won't find out for a long while, but if that's the case then this man must certainly be the leader of the Corps.

"Oyakata-sama, I am glad to see you are in good health, I sincerely pray for your continued good fortune." Sanemi had said, the same man that brutally pushed Nezuko to the ground, the same man that looks like he would just stab Tanjiro if he had him in his hands, just to poke fun at him, the extent of the respect the leader had gained, "Thank you, Sanemi."

"Dammit, I wanted to greet the master!" Mitsuri pouted to herself as Sanemi continued, "I'm sorry, but before the Hashira Meeting begins, would you be so kind as to inform us about the corps member that travels with a Demon?"

"Ah, I apologize for surprising you." The Master began, "But Tanjiro has already been initiated into the corps himself, I sanctioned the Kamados' situation, and I would like you all to accept that.", his words seemingly caught all of the Hashira by harsh surprise, a few audible gasps shortly filled the air.
"...Even though the Master requests it, I cannot accept it." Gyomei answered, "I too am flamboyantly opposed to the idea, a Demon in the corps? I won't accept it!" Tengen chimed in.

"I will do anything you say, master!" Mitsuri said, before Muichiro gave his own thoughts, "It doesn't really matter to me, I'll forget anyways."

"I won't accept it, I loathe demons." Obanai answered, "Master, with all my respect, I can't accept the idea of a Demon being part of the corps. I am against it with all my strength!" Rengoku answered right after.

"The Demon Slayer Corps KILLS Demons, please punish Kamado and allow us to kill the Demon in question." Sanemi finally said, through all of this Giyu and Shinobu had remained quiet.

"Well then, the letter." The Master said, getting a confirmation from one of the children beside him who pulled out a letter.
"This letter arrived from Former Hashira, Urokodaki Sakonji. I will read a portion of it." the child began as they unfolded the letter, "...Please forgive Nezuko for being with her brother who has become a Demon. Through strong spiritual strength Tanjiro maintains his human reason. Even when starved he refused to eat human flesh despite having tasted flesh and blood, he has remained this way for more than two years even while joining his sister's harsh training. It is difficult to understand but it is undeniably the truth. Should Tanjiro ever willingly attack a human person, together with Nezuko, I, Urokodaki Sakonji, alongside Tomioka Giyu, will atone by slicing open our stomachs."

There was a moment of silence, the Kamados looked over at Giyu who had remained silent and unmoving, tears broke out in Nezuko's eyes while Tanjiro's shot open with wonder, these people were risking their lives to prove his innocence, Tanjiro's innocence, his humanity, the same humanity Muzan had attempted to take from him.

Although, not everyone saw it the same way, which was clear when Sanemi stood and spoke up, "So what if he commits Seppuku?! If he wants to die, he can rot for all I care.", and Kyojuro agreed, "Shinazugawa is right, if he kills someone that is irreversible, we can't bring back the dead."

"That is correct." The Master simply responded, "We cannot prove he won't attack someone, however… You can't prove he will, either.", a sentence that took Sanemi off guard entirely, his posture faltered during the realization.
"It is a fact Tanjiro has not even attempted to bite someone for over two years, and three people have staked their lives on him. If you would reject this, you will have to offer something greater than Urokodaki's promise."

The silence returned as the Master shut down the opposing words, showing his own strong belief in the Demon Boy, now it was Tanjiro's turn to tear up, luckily it went unnoticed… By almost everyone.
"Even as a Demon he's so cute… I hope they'll come to respect the Master's wishes…" Mitsuri thought as she noticed the first few tears streaking down the boy's white skin, he had so far brought everything they knew about Demons on its head, he refused to eat people, he showed very clearly human emotions from the events, and back then he even called out to his sister, to make sure she was okay…

"Furthermore, Nezuko has supposedly crossed paths with Kibutsuji."

Once more, everyone's gazes locked onto the girl firm on the ground, "N-No way!" Sanemi began, "Are you saying that though no member of the Hashira has ever faced him, this girl has!?", the gazes widened in shock and interest, before Nezuko felt herself bombarded with questions left and right, they wanted to know everything, his appearance, his abilities, where it took place, etc.
It was incredibly overwhelming, Tanjiro couldn't see Nezuko's face anymore considering she was surrounded by all the Hashira now, but he could smell her silent disbelief and how overwhelmed she was, it painted a small smile on his face because of everyone's behavior that changed so drastically.
From afar, it was kind of cute actually, how everyone suddenly swarmed his little sister, but then his eyes met the Master again as they slowly raised their hand, before making a shushing motion with his finger, the soft "Shhhh." soon escaped his lips and instantly the Hashira were back in a line, bowing and silent.

"Kibutsuji has sent his forces after Nezuko. He may simply wish to silence her, but for the first time Kibutsuji has shown his tail and we have grabbed, I don't want to let go now. And, it's possible Kibutsuji has seen something unexpected in Tanjiro aswell. Do you understand?" the Master spoke, earning another short silence before Sanemi let out another burst, "No, I can't understand! Letting a human live, sure, but a Demon!? I can't agree with that, there is nothing normal about it.", He stood up firmly grasping the handle of his sword, "Pardon the intrusion." he said as he leapt onto the patio, approaching Tanjiro while everyone else remained silent, Tanjiro's eyes were firmly locked on Sanemi, what was he going to do? Was he just going to flatout kill him?

"Master, Demons are ugly and untrustworthy, I'll prove it to you!" Sanemi yelled as he unsheathed his sword, and made a deep cut in arm which he held out, blood soon spilled out infront of Tanjiro and the scent entered Tanjiro's nose soon after, who's eyes widened immediately as a response, fangs bared unconsciously as the first few groans escape his throat.
"H-He's- Dammit! He's got Marechi!"
