Next morning, the people of Demon Slayer Corp gathered together in the hall.
Kagaya Ubuyashiki gave everyone the letter with their names to them and said, "Last night, Shadow Pillar Liu Mengmeng left silently, and Love Pillar Mitsuri, Tanjiro and Nazuko also left with her, leaving these letters."
"Really they left without saying goodbye and just left letters."
"Lord, do you know where they left, I will visit them during my travels."
"Hey, I thought everyone will stay together for few more days. Who knows they left without saying a word."
The Pillars kept talking, some complained, some accepted peacefully. Kagaya Ubuyashiki didn't say anything and waited for everyone to stop.
"I have a letter that addresses to all of us. I will read it out now." Kagaya Ubuyashiki said and everyone waited for him to continue. He held the letter in front of him and read it aload.
"Hi everyone, this is your favorite Shadow Pillar, Liu Mengmeng. When you read this, I would have gone to a far away place. Don't try to search for me, you wouldn't find the place where I have gone. Mitsuri, Tanjiro and Nezuko are also going there with me. Now, back to topic, I know that most of you are worried about side effects of demon slayer mark, so I have left something that can help you, remember to learn it. At last, you all are good and excellent people, I wish you all live a happy life with your loved ones. And I have enjoyed my stay in Demon Slayer Corp with you all very much. So, everyone, goodbye, see you again by fate."
Everyone in the hall have different emotions after hearing this short and simple message. They were all collectively silent, not knowing what to say.
"The thing left by Shadow Pillar is an advance Breathing technique. It says that by practicing it can slowly eliminate side effects of the demon slayer mark." Kagaya Ubuyashiki broke the silence and showed the copy of Normal type breathing method to the Pillars.
"Do you think Shadow Pillar has returned to divine realm?"
"Divine realm?"
"Come on, don't tell me that you don't think that the Shadow Pillar is incarnation of some god after the final battle."
"Of course I thought so but it was too incredible to say this."
"Actually I thought that too."
"Me too"
"Me too" * N
"See, everyone of us thinks so."
The Pillars were talking and arguing.
"Actually, I had sent someone to investigate about her when she first became Shadow Pillar but no information was found at all. It was as if she suddenly appeared out of thin air." Kagaya Ubuyashiki interjected.
"Look she appeared out of thin air, is mysterious all day, can magically heal, the badges given by her can save lives, and she is stronger than all of us even stronger than demon king Muzan. If she is not incarnation of some god then what is she."
"But if she is incarnation of some god, then why didn't she appear earlier and kill demon king Muzan?"
"Actually, a God may have appeared earlier."
"Who are you talking about?"
"Yoriichi Tsugikuni, the inventor of Breathing styles." Kagaya Ubuyashiki paused before continuing, "According to records, the Breathings were created by him and selflessly shared and taught to everyone in Demon Slayer Corp during his time. Lady Tamayo has told me that Muzan was nearly killed by him but unfortunately, Muzan escaped by splitting himself to 1800 parts but 1500 parts were destroyed before they can escape into different direction."
"Muzan was so terrified that he went into hiding, and that Muzan in his full form and strength. And we had difficulties fighting a Muzan, who was weakened by medicines, when we were fighting together."
"Although Shadow Pillar didn't participate in many battles but she will always arrive at critial moment and has saved many of us. And which one us had not become stronger because of many constant spars with her and her advices."
"If Yoriichi Tsugikuni is Sun God who taught breathing and created a new day for Demon Slayer Corp then Liu Mengmeng is Moon Goddess who helped us in the darkness and finished the day."
"Why Moon God? Isn't Mood God male."
"Idiot, look at the badge on your chest."
There is the moon shaped badge hanging there. This badge was given to them by Liu Mengmeng and it also helped them during final battle.
"Not to mention, who said that Moon God must be male."
"Everyone, since we know that we were helped by both Sun and Moon gods, we shouldn't keep it hidden. I have decided to use the power of Ubuyashiki family to spread their deeds as much as possible." Kagaya Ubuyashiki informed the Pillars of his decision.
So, everyone in Demon Slayer Corp thus prepared a heavy surprise for Liu Mengmeng.
