(Friends this is the longest chapter I have ever created!! Needs rechecking, please tell me if something is wrong ASAP)

Kagaya Ubuyashiki has arrived.

And the serious pillars are still kneeling down to their master in a respectful manner.

Kagaya glances at the hero who is sitting at the ground with nonchalant look. Kagaya then says "mister Saitama, I believe you accompanied Tanjiro and Nezuko in their journey, no?"

The poker faced Saitama who is sitting then looks at the pillars' master, the hero looks down while thinking and carefully making his own answer, then the hero looks back at Kagaya as the hero speaks in honest tone "yes, I have been accompanying them since Tanjiro became an official member of the corps, but how did you know my name?" The hero then scratches his head in confusion.

The pillars who were listening, remained serious and obedient as they continue to kneel, they didn't intervene in the conversation between Saitama and their leader because they know that Saitama and Tanjiro will be undergoing questioning later.

Tanjiro behaves while listening to the conversation, but he was worried and thinking like "I hope Saitama will be okay....I hope he will be not in trouble like me..."

Kagaya chuckled in friendly expression to the hero, he never thought the hero would asked the obvious question. The leader then speaks in gentle and friendly tone "my apologies, I was too excited to ask some questions that I forgot to introduce myself, my name's Kagaya Ubuyashiki, the leader of the demon slayer corps and the owner of this estate, as you know, I am the 97th leader of the demon slayer corps....."

Kagaya paused as he then blinked his eyes while smiling in warm and assuring expression as if he was the most trusted man, the leader then speaks "...to answer your question, the messenger crows are always active in delivering any important news like activities, possible dangers and anything related to demon slayer corps everyday, that includes your identity since you accompany Tanjiro."

Kagaya then looks at the serious pillars kneeling down.

Kagaya then says "children, I have to let you know that mister Saitama and Tanjiro meet Muzan Kibutsuji at the Asakusa Tokyo..."

The pillars after hearing it became deadly silent and also shocked at the same time, they were flabbergasted.

"What!? Impossible! Not even a hundred years a pillar meets him in person! Not even an upper moon!" Says the disbelief Tengen.

"So did you battle him?" Says Tokito with expressionless face

"Oi brat answer the master! Did you battle him!?" Says the angry and annoyed Sanemi as he grab Tanjiro's hair and shake Tanjiro's head.

"N-no...." Tanjiro replies while getting dizzy.

The pillars then looks at the hero with their piercing eyes as they ask "hey baldy, did you battle the demon king?"

"Uh no..." Saitama looks down while his right hand on his chin, then he looks back at Kagaya with curious expression "but can I ask some questions? are you sick? Your face looks bad..."

[Shock gasp sounds of the pillars]

"Oi oi oi....!" Tengen in taunted Expression

The pillars excluded Tokito were a little bit offended by the hero's curiosity, asking that question is just beyond stupid. But to the hero Saitama, he was just worried as he might think he can help to solve the leader's problem

But..

"Oi! You stupid ignorant baldy! Don't you dare ask my master about that stupid question! Do you want to die miserably!??" Shouts the angry Sanemi while holding Tanjiro's head.

"Master, should I cut his tongue as a punishment? He insulted your appearance, that is unforgivable and must be punished..." The serious Tengen proposed while his hands hold his cleavers at the back, ready to unsheathe if Kagaya agrees.

But, the calm Kagaya who is still smiling in friendly expression, shakes head and refuses the pillars' threats.

"Children, calm down, mister Saitama was just curious of my appearance, that includes my sickness...so please forgive him this time as I also want to share my secrets with you all" Kagaya's tone didn't change as he remain honest and forgiving.

"But....!" Says Tengen who disagree with Kagaya.

"Tengen, please...." Kagaya smiling warmly and pleading Tengen to calm down.

"Yes...if that's your wish, I'll respect it with my utmost heart" Tengen kneel down more with his serious expression, but his hands shiver as he can't accept his master getting insulted

Kagaya shifted his look to Saitama as he smiled brightly "mister Saitama, let me answer your question about my deep secret...but first let me ask you if you will side with us and fight for us in battling demons"

The hero nodded and behaves well "I hate those human-eating demons, I will definitely use my power in defeating them"

Kagaya nods in friendly expression and says "will you accept my children as one of your important allies? Help them in times when they needed your help?"

The hero nods at Kagaya's request.

"I will, unless if they try to harm one of my comrades, that is a different story..." Saitama in his poker self.

Kagaya with unchanging expression nodded, he then says "last question before I tell you my secret, will you and Tanjiro see me as a leader of the corps?"

Saitama didn't hesitate to answer in honest tone "ofcourse, If the pillars see you as a great leader and even respect your decisions, why not? I fully trust you and will see you as one of a leader" Saitama then smiles warmly.

Tanjiro while forced to bowed down from Sanemi says "I will also trust you master Kagaya and will see you as a great and forgiving leader, with my power I will slay all demons until my life gives up!" In brave tone.

Kagaya was extremely pleased of their responses, he was happy that Tanjiro and Saitama finally acknowledge him as their trusted leader, his heart can't contain the happiness especially he believes Saitama and Tanjiro will be the hope of defeating the demon king.

Kagaya then says "I'm grateful of your services, and now let me answer about mister Saitama's question about my appearance.."

Saitama then becomes serious as he want to know why the leader's face has a burn mark, the hero is even overthinking and is quite disturb about possible truth.

The pillars also continue to kneel down as they listen attentively to their master.

Kagaya clears his throat as he speaks "If you know about Muzan Kibutsuji, you will know why I have a sickness like this...my family and Muzan have blood relations centuries ago, due to Muzan becoming demon and becoming the progenitor of the demons, the Ubuyashiki family such as me developed a curse like this that is incurable unless the demon king is defeated....I hope that explains your question mister Saitama..." He then smiles warmly to the hero as warm as the heat of the sun.

The hero looks down as he thinks "So the only way to cure your illness is to defeat that Micheal Jackson guy? Sounds pretty easy for me, if I could find him, I will bring his head to you since he is a bad demon..no maybe I will put him into a cage first and make him plead for your forgiveness..."

[Other pillars where letting out a chuckle at Saitama's comment]

"Huh? What a great nonsense are you talking about? Doing that impossible thing like putting the demon king to cage is just a dream you can imagine..." Says the expressionless Tokito who is annoyed of Saitama's thoughts.

"Do you really think a pathetic human like you can do that? And who's Micheal Jackson huh?!!" Says the angry Sanemi

"He is just daydreaming, leave that weirdo, he is not worth it, just rot away and get punished" Says the serious Obanai while still kneeling down.

Mitsuri was holding her laugh about the thought putting Muzan to cage, she looks away and covers her mouth as possible as she can "I'm sorry I can't...pffftt~"

Sanemi interrupted as he says "but master, how about the case of them protecting a demon? This is alarming for us especially they betray the corps rules"

Kagaya continue to smile in friendly expression as he nodded at Sanemi "yes Sanemi, let's discuss about that..."

One of Kagaya's relative gave him a message scroll. Kagaya opens it as he reads the letter "listen to me children, this letter is from the former water hashira named Sakonji Urokodaki"

Saitama smiles as he was surprised about Sakonji helping them in their dire situation "hoh! That old man finally noticed our problems and decided to help us!!"

The pillars continue to kneel down as they listen to Kagaya's message. Kagaya smiles as he speak in gentle tone "Nezuko Kamado is a harmless demon, I have confirmed this as a former water hashira, Nezuko Kamado as a demon sleeps for 2 years just to compensate her hunger instead of eating humans, even when asleep, she also knows how to interact humans such as me and her brother Tanjiro, in such cases if Nezuko rebels us, Sakonji Urokodaki and Giyu Tomioka will be held responsible for the problem and will be punished...." Kagaya then puts the scroll down as he stares at the pillars with warm and friendly smile

Sanemi quivers in annoyance as he can't accept the demon Nezuko to be part of the demon slayer corps, he stand up and released Tanjiro from his grasp as he says "master! Allow me to prove you that this demon is dangerous to us!!" In his sadistic behavior.

"Sanemi! What are you gonna do?" Says the stern Shinobu.

"C-can we just be peaceful instead of fighting today?" Says the concerned Mitsuri while playing with her fingers.

The pillars where watching Sanemi grabbing the box and stabbing it, creating a hole.

Tanjiro grit his teeth as he says in panick tone "Hey what are you doing!??"

Sanemi cut his left arm with his sword, bleeding it as his blood drip on the box "hey demon! There's a tasty blood for you! Come and lick it!" Says the excited Sanemi.

Obanai proposed "Sanemi, that demon won't come out if the demon is exposed on sun, do it inside..."

"Yeah right! I should bring this trash to the stage so all of you will see how this demon reacts to my blood!" Sanemi grabs the box and went inside the stage.

Tanjiro with wide eyes shouts to the wind pillar "Hey! Don't you dare hurt or provoke Nezuko!!!" And Tanjiro tries to run over to stop Sanemi.

Tanjiro in his mind: "this is really bad! If I don't do something to stop him, Nezuko will succumb to his blood and eventually become a full demon!"

Tokito saw Tanjiro trying to stop Sanemi so the mist pillar throws some pebbles to Tanjiro's face, temporarily knocking Tanjiro off and dropping him in the ground.

Saitama also tries to stop the wind pillar but Tengen, Rengoku and Gyomei blocked his way. The hero in dead serious expression says "oi, are you all going to stop me? That guy is just provoking our comrades!"

"Master didn't stopped Sanemi in doing what he wants just to prove the innocence of the demon, so he wants to know if this demon can really be trusted" says the serious Gyomei who's eyes still stream with tears.

"Just don't try to fight back, and we will never have a problem!" Says the smiling Rengoku to the deadpan Saitama.

Tengen while acting dominant says "that's right baldy! Obey master and just see for yourself, let the master know if those people says the truth!"

Saitama looks down with a hesitating action, he wants to stop the wind pillar but due to their point in proving Nezuko's innocence, the hero can't do anything but says "alright, if you try to hurt her, I'm not gonna forgive all of you..." Says Saitama who stands and behaves around them while the pillars continue to block the hero's way.

As Tanjiro tried to run and stop Sanemi, he was elbowed by Obanai again "why are you so stubborn, should I just cut your legs so you will obey us!?"

"Gnnnnmm damn it! Nezuko don't try to eat or drink his blood!!!" Shouts
