After helping out Mitsuri free herself from her limitations she is now also a Spiral Energy User and now no matter what she uses to attack she will be able to deal massive damage to things that carry negative energy such as this worlds Demons and other World's undead monsters, but her Nichirin blade is also very helpful in that regard as well.
Not only that she had been able to complete her 13th Form from being able to overcome her past and thus another form was created, and the thirteenth form of any of the breathing techniques is consider the final and strongest technique of their own styles.
"Now then with that out of the way, I plan on dealing with one of the Upper Moons, can't exactly have one of the Upper Moons that nearly killed Kanae to still be walking this earth." I said as I cracked my neck and placed my blade up on my shoulder.
"Oi oi, you planning to have all the fun for yourself?" Sanemi said as he stopped me as I stared at him.
"Well that depends, are you immune to being frozen solid like an icicle?" I asked him with a raised eyebrow which made his eye twitch.
"I'm not looking down on you, but some Hashira are good against others based upon their breathing styles, if you were pitted up against Upper Rank Three then your speed and strength would put you on even fighting level with that guy." I say rubbing my chin while Sanemi ground his teeth but the same time Rengoku came over to me.
"Actually Hifumi I've been meaning to ask, if you know of Muzan and some of the Upper Moons, then do you by chance know of the other Upper Moons?" He said as I looked to him while I kept rubbing my chin.
"I do, and I am willing to tell the Demon Slayers, but before I decide to have that conversation I think it's best me and Kagaya have a private chat with one another." I say turning to Kagaya who was quietly drinking tea while everything was happening.
Hearing this he put down the tea to which his wife took away before he stood up and looked at me, "If that is what you wish Hifumi, I am willing to oblige." He said with a slight nod to which I nodded back.
"After our discussion I'll have a meeting with all of you, we will meet in the largest room in the Manor." I say looking to the rest of them as I put my sword back on its hilt before I followed Kagaya to have a private conversation with him.
After a short walk, passing the interior garden we came upon a small private room as we went in to where I shut the door behind me while several invisible barriers were erected to keep this conversation private.
Soon enough we both sat down on cushions sitting apart from each other with a small table in between, "So Hifumi, what is it you desire to talk about?" He said with a calm look on his face.
"Well…."
…

"I see, that is very surprising, and if any other person said that almost everyone in this world would call you crazy, but like I have said before, I have a good read on people, and I can tell everything you said must be true." He says calmly after listening to everything I had to say and the truth of who I am and where I'm really from.
"And as I said after Muzan is defeated I don't desire the Demon Slayers to be disbanded, I have ways for them to continue growing in other ways, and in fact allow them a path to another world in fact." I said to him as he seemed deep in thought.
"Then I shall agree, help us deal with the threat that is Muzan and Kibutsugi and me and my Demon Slayers will be at your aid, though after this we will need a new name for our group, what is it you said that profession was called again?" He asked to which I grinned.
"Monster Hunters."

A short while later, in the main hall of the Demon Slayer Head Quarters.
"Alright listen up, this is a meeting on the Six Upper Moons, Nakime and Muzan, all of which provide a vital part in the Demon Crisis Japan is now facing." I said before snapping my fingers as a chalk board appeared behind me, but no one really questioned how I did that as my powers seemed completely out of this world to them so whatever I did just seemed normal to them now.
I then went to the large Chalk Board putting up near perfect Artist renditions of every single Upper Moon along with Muzan and Nakime, artwork I drew myself during my conversation with Kagaya along with opening his Aura to slow down the Curse that was consuming his body, it's a stopgap from it getting worse but I sent a cure in the way of Demon Slayer Marks.
"Alright these are the Upper Moons, Ranked 1 through 6 along with Nakime and Muzan, now I can see a bit of confusion as to who Nakime is but simply put, she's the main reason why no Demon Slayer in the last hundred or so years has been able to track down Muzan unless he so desires to be seen." I said before using my pointer stick and starting on Daki and Gyutaro.
"These two siblings share the title together of Upper Moon Six with the Brother, Gyutaro holding the primary title while is sister, Daki, shares it with him." I say before moving on.
"Daki is the face of the two as she is the most seen by people as she is working in disguise as a Orian in Tokyo's Entertainment District in the Yoshiwara area, she goes by the title of Warabihime and does the killing and eating of humans for the both of them do to their special bond between brother and sister."
"Daki and Gyutaro have a trait that only the two of them have as sibling demons, and that is that to kill them they must be killed at the same time as their lives are linked to each other and as such they both must die at the same time to kill them."
"As for their weapons Daki uses her Blood Demon Art to control her flesh Obi to attack others, while Gyutaro uses a pair of Kusagami Scythes, and what's worse is that each scythe is covered in extremely deadly poison that would kill a normal person in agony, along with the fact they if either of them went all out they can easily destroy the entire Entertainment District."
"That being said the two Hashira that would be perfect for the job to deal with them would be the combination of both Tengen and Mitsuri, Gyutaro's poison wouldn't have that much of a an effect on you, on top of your newly acquired Aura your body should either be immune or nearly immune to all poisons now, and Mitsuri would be able to easily deal with Dali's various Obi based attacks." I point at the two of them.
"Ha! With my technique's and my old skills as a Shinobi, dealing with a Demon with Poison based attacks will be a breeze." Tengen said patting his chest with a bright smile on his face.
"Leave it to me Hifumi!" Mitsuri said with a cheery tone while smiling brightly at me.
I nod, "Good, now let's move onto the rest." I say as I begin to explain the rest of the Upper Moons, Nakime and Muzan's powers and who will be best to deal with them.
