(A/N: Reminder, the Upper Moons do not know who Y/N is except Hantengu and Kokushibo. As they have been demons for more than 200 years.)
"We're here, Y/N-Sama." Nakime said with her hands on the sliding door waiting for her master to order her to open the door. "Nakime, please tell my son that I will enter the meeting right now." Y/N commanded. Nakime bowed and knocked on the sliding door.
"What?!" An annoyed male voice was heard behind the doors. "It's Nakime, Muzan-Sama." There was a silence after Muzan heard Nakime's voice. "Enter." Nakime quickly entered and bowed. "I greet the demon lord, Muzan-Sama." Muzan was definitely busy right now. The Upper Moons (excepts Kokushibo and Hantengu) were all staring at Nakime. I mean yea they have seen Nakime walking around the infinity mansion before but Nakime has never spoken to Muzan, all she ever does is stare at the background. So, seeing her here right now was kind of weird.
"Is there anything you need right now Nakime? As you can see, I am very busy right now." Muzan gave a cold glare to Nakime, making it extra obvious that he was annoyed with an uninvited guest. But knowing that Nakime is one of Y/N's subordinate, he knew something was wrong because Nakime rarely visits him.
"Umm." Nakime was getting nervous as she felt the lingering stares by the Upper Moons. She wanted to quickly get over this so she gulped down her saliva and said "Muzan-Sama, Y/N-Sama said she wanted to join the meeting. And she's actually already waiting by the door for your approval."
After hearing this, most of the Upper Moons were confused. "Who is Y/N?? Why did Nakime called her 'Master'?? Isn't Muzan-Sama be Nakime's one and only master?" All of them had the same thought. Hantengu just gave a side glance to Kokushibo, "Should we greet Y/N-Sama if Muzan-Sama allows her excellency to join the meeting". As if Kokushibo could read minds, he noticed Hantengu glancing at him and gave him a nod.
Muzan was in a tight spot. He wanted Y/N to go back to her chamber to rest. But she's already outside of the door. Knowing that Y/N had to walk to the meeting room but ended up getting rejected would waste his mother's energy to walk here. So, he had no choice but to reluctantly agreed.
(A/N: As you guys know from the previous chapter. Y/N does not eat humans. She only feeds on Muzan's blood. So, she does not reek of human blood / flesh. Of course, she doesn't has reek a strong smell of demonic blood like most demon does. And since Y/N does not eat humans, just like Nezuko, she needs a lot of sleep to replenish her energy.)
"Alright then, I will inform it to Y/N-Sama right now." Nakime quickly walk towards the sliding door and slides open the door. She peeped her head to find her master. Finally, she spotted Y/N who was looking outside the window admiring the night sky with the round moon hanging in the sky.
"Y/N-Sama!! Muzan-Sama has allowed you to enter the meeting room and participate in the meeting." Nakime said notifying Y/N. Y/N closed the window and walked into the meeting room with Nakime walking behind her. The Upper Moons were in awe of her beauty. She looks frail and quite fragile but the aura radiating from her said otherwise.
"Who's she??" Upper Moon 2 couldn't help but wonder. "Well, none of us obviously know." Upper Moon 3 gave Upper Moon 2 a sarcastic remark. "Honestly, she looks gorgeous!!" The younger Upper Moon 6 said.
While the other Upper Moons were busy talking, Kokushibo and Hantengu bowed and said, "Upper Moon 1 and Upper Moon 4 is pleased to be in the presence of Y/N-Sama." "Wait, Kokushibo-Dono and Hantengu-Dono know her?!!" Upper Moon 2 whispered to Upper Moon 3. "Thanks captain obvious." Upper Moon 3 spat another sarcastic remark.
"You may rise, Kokushibo and Hantengu." Y/N smiled at them. "Hantengu it has been a long time since we met. How have you been?" "Yes it has been a long time, I have been getting lots of tasks lately so I couldn't visit you because of it and I have been doing well, Y/N-Sama." Hantengu couldn't help but smile when he's talking to Y/N. He liked how Y/N is always caring of him like a real mother. His mother had never really care about him so having someone like Y/N around he definitely felt more loved.
Y/N sat beside Muzan, Nakime is currently serving Y/N freshly brewed tea. "Mother, what are you doing here? I thought you would be sleeping." Muzan whispered into his mother's ear. "At this time I should be but recently I've been thinking when I should reintroduce myself to the newer Upper Moons. And you were having a meeting so I thought this could be the perfect moment for my debut."
Meanwhile when Muzan and Y/N were talking, the Upper Moons were now all gathered together whispering to each other. "Kokushibo-Dono, Hantengu-Dono, could you please tell us who she is??" Upper Moon 2 asked both of Upper Moons. "And what's her relationship with Muzan-Sama? They seems quite close." Upper Moon 5 said.
"First off, she is Y/N-Sama, Muzan-Sama's mother." Hantengu answered the curious Upper Moons. "REALLY??!!" this definitely shocked the Upper Moons especially Upper Moon 2 and 3 since they were the top 3 within the Upper Moons, they thought that they should at least knew about Y/N's existence as Muzan's mother more than anyone.
"Yes really!! Oh and, Muzan-Sama and Y/N-Sama have a close relationship so we must protect Y/N-Sama with our everything if she's in trouble one day. Plus, she's the most nicest person I ever met, I don't see any reason why anyone would hate her." Hantengu said while Kokushibo just nod confirming what Hantengu said is true.
"I really really want to know how you guys met her." The younger Upper Moon 6 asked, though the older Upper Moon 6 seems like he doesn't care but he actually does want to hear the interesting story as well.
Hantengu began to blabber words. "We met her a long time ago, when we were selected as Upper Moons. She was standing on the second floor seeing who has been promoted to be the Upper Moon. Because she was silent that time, we all thought she was a scary person. And after we learned the truth of her being Muzan-Sama's mother. We thought that she would definitely kill us if we became useless one day. But as time passed, we managed to spend time together. I soon found out she was a very nice person."
