Both Muichiro and Kyojuro are on their stance, with Wooden swords in hand while the Pillars watching them, sitting on the bench. "Your body temperature is 39 degrees Celsius, you are sick." Says Shinobu "It's a part of my mark, that's all." Said Tanjiro, leaving her to worry. With Muichiro asking Kyojuro "Ready?" As Rengoku replied "I'm all in, Set your Heart a blaze!" He readies his stance as Muichiro charged at him, throwing crescent shape type slashes, as for Kyojuro deflecting them 'He's fast, Really fast. His Swordsmanship is in a different level' A crescent moon and flames flowing around, Rengoku seems quite impressed from how talented he is, both in such speed that only the pillars are able to read their movements.

While Tanjiro closing his eyes, breathing harder, as Tengen asked "what are you doing?" "Trying to maintain the mark." Says Tanjiro and Gyomei asked "it does increase your abilities, does it? Is it possible for us to manifest it." "As long as I'm here, yes." Says Tanjiro and Sanemi scoffed and says "..Tch...Sounds simple then." "Having such a simple mind while you call this simple. I envy you." Says Giyu as Sanemi and Obanai glared at him in hate as Kanae laughed little as Tanjiro says "Don't take this Mark as some child's play. It's never easy to manifest it." While he and the others are watching the fight.

Muichiro and Kyojuro sparring like crazy as "You are quite Talented Young Tokito!" "Then let's see it then!" Says Muichiro as He prepared his stance "Moon breathing, 6th form..." "Flame Breathing, 4th form..." Muichiro dashes around and rushed to Kyojuro in speed, "Light Boomerang, Blue moon." "Blooming flame Undulation." Kyojuro deflected Muichiro's slash but that didn't stop him, he rushed out and dashed off, rushing from behind. Kyojuro immediately deflects it as it goes on, Muichiro Dashing and Slashing all around Kyojuro while he's performing multiple slashes and does his best to deflect every slash coming, from the speed dash. "Flame Breathing, 3rd form..." "Moon breathing, 1st form..." Kyojuro on a high ground and Slashing downwards from a vertical motion "..Blazing Universe", as for Muichiro dashing to Kyojuro and performing a horizontal crescent shape slash. "...Shining Moon, Evening Palace." Both swords clashed, only for Muichiro's to shatter, and Kyojuro striking Muichiro to his chest, leaving him on the ground.

"Rengoku takes the win." Says Gyomei, as Kyojuro offers Muichiro his hand, as he takes it as he stands up. "What a Flashy battle." Says Tengen who was impressed by Muichiro's speed and his breathing technique. Mitsuri was smiling and blushing over these cute boys as she calls them so. As for Tanjiro smiling and saying "You got Stronger Muichiro." While Muichiro and Kyojuro are taking a seat, and Muichiro says "Well, we were evenly tied, and now you got stronger than me from that mark." "True enough, but I'm in the need to maintain it." Says Tanjiro.

As time passes, most pillars are going on separate ways, with Giyu, Kanae, Shinobu with Tanjiro and Muichiro on their way to the butterfly mansion. "What a match that was." Says Shinobu, Muichiro walking on his way, "Well, i wonder how far we'll get once time passes on?" He says while Giyu replied "that depends how much you experienced. Keep training harder, they're many things you need to learn." "Of course." Says Tanjiro.

Meanwhile in the mysterious place, where all houses are combined in one, The Infinity Castle. As some demons, with kanji on their eyes, Lower moon, 6, 5, 3 and 1. Summoned all around the castle, as for lower 3 to ask in thought 'What the? Where am i? How did I get here?' only for a Biwa to be played by one tap, as they all got pushed by the castle's transformation, walls rushing to them, pushing them in one place. The moons were confused as they saw Muzan in has Casual form, they all immediately bowed to him. "Muzan-sama." Says Wakuraba, Lower moon 3. Muzan, sitting on a chair couch while he faces to them, "Sit up, on your knees." The lower moons does so, as Muzan who looked disappointed "Rokuro and Makugo are no longer here...And they weren't defeated by pillars. But rather 2 slayers in each, both are already Pillars by now. Makes me wanna ask, How long are you going to Keep toying with the slayers?" He asked as for the moons, "Makugo, using her plant sense to run of and hide from the pillars like a literal Coward and then there was Rokuro just casually thinking some slayer would be fun to toy by playing with magnets." The moons weren't sure what to say, 'I knew this was gonna happen, i warned them, but they didn't listen.' thought Wakuraba only for Muzan to say "Warning them yourself won't do good." "My apologies, Muzan-sama. I don't plan on Toying with the Slayers. And i don't plan on running away from the pillars. Since i haven't encountered any." Says Wakuraba and Muzan staring at him and saying "which of course is true. You just became a moon after all." Muzan then faced to Lower moon 5, Rui. "As for you Rui, no flaws coming out of you, i would give you more of my blood." "I don't need it, I'm proud of what I already have." Says Rui, only for Muzan to reply "Even so, You are wasting your blood by creating your own demons. That will weaken you for sure when you encounter a pillar.." 4 tentacles flew towards their necks, with a slight amount of blood being injected, the 4 fighting the blood, trembling down at the floor. "as such, this is what you all must understand. Don't underestimate the one with Hanafuda Earrings, I warn you." As The Biwa plays with the lower moons being thrown off in many different places separately.

One month passed since the promotion, Tanjiro and Muichiro as pillars are slaying demons effortlessly, saving many slayers. As days passed by, Tanjiro in the butterfly mansion, sitting on a Porch, Reading Yoriichi's Journal, only for Kocho Kanao to come in with a plate of rice balls, Tanjiro turned to see her after picking her scent up. "Oh, Kanao, you brought rice balls?" Says Tanjiro while Kanao sits next to him. "Yes, You're about to leave to your estate, I wanted to give you something before you leave." She says it as Tanjiro takes it as he eats it, "it tastes good, thanks." "It's the best i could make." Says Kanao while she smiles gently as for Tanjiro, "you did well, I'll make some for you next time, does that sound good?" Kanao nodded, until "are you both done flirting?" They both looked behind and saw Giichi, crossing his arms and smirking while raising his eyebrow. Both Tanjiro and Kanao blushed slightly while Giichi says "leaving that aside, Kamado. Tokito is waiting for you. Your estate is reported finished." Tanjiro stands up and says, "yes," as he finishes his rice balls. "I'll be going Kanao, Sayonara!" As he runs off, while Kanao was left in silence, blushing a little and Giichi then standing next to his auntie Kanao, "Everything okay Aunty?" Kanao nodded, "Oka-san's waiting for you and your training to continue." Says Giichi with Kanao standing up as she bowed to him and leaves.

Both Tanjiro and Muichiro arrived at the Estate as it's names Eclipse Mansion, as a mixture of Sun and Moon. "Only a month it took." Says Muichiro, "They're quite fast." Says Tanjiro. "Now that we have it, we can proceed in training our low ranking juniors." Muichiro faces him and replies "You have a point, we can't just sit down, train on our own while we are at it. We need help others get strong enough as they can be.. right now, I need head to the Swordsmith Village, and get a new sword." "New sword?" Asked Tanjiro "isn't your sword in good Shape?" "It is, but my crow told me to head to the village. For a new sword, it's probably because of me being a Pillar." Says Muichiro, "Pillars have a kanji written on their sword. So i guess it makes sense for that to be the case." "Oh, I'll be seeing you then?" Says Tanjiro and Muichiro smile and says "of course, I'll be okay on my own. You can focus on our Comrades." Tanjiro bowed to him and said "Yes, I wish you luck."

"Excuse me, Tokito-sama." A Kakushi appeared out of nowhere, leaving the Duo to be stunned. "Oh, me?" Asked Muichiro, the Kakushi bowed as she "I shall be carrying you and transporting you to the Swordsmith Village, since it's a place strictly hidden, you must wear these." She shows him a blindfold and earplugs, with Muichiro wearing them as he gets carried in the back and as the Kakushi runs off. "Safe journeys Muichiro!" As Tanjiro makes his way inside and saw how well the estate is made, there's a large training hall, there's a hot springs a little further away, the yard is really large, so many rooms and a large kitchen with tables. As such, Tanjiro was amazed by it. "What a mansion, Nezuko is going to love it here."

A day has passed and Tanjiro in the headquarters having an Audience with Kagaya, "I'm happy to know that the estate has been finished, may i hear what request is it that you wish to have?" "Do you by any chance have all the names of the slayers who Muichiro and I accompanied with for the last 2 months?" Asked Tanjiro and Kagaya in his typical smile, and replied "I have a list apparently. What about it?" "My missions with them, i could speculate that some of their weak spots remains, Muichiro and I planned on training them. Helping them out as we can. And same goes for low to half ranking slayers." Says Tanjiro and Kagaya seems amused and says "How thoughtful of you, I will allow it. So you're aren't planning on taking a Tsugoku?" "My sister is going to be my tsugoku, that's for sure." Tanjiro replied and Kagaya asked "Nezuko is it? How is she? Kanae told me about her having a blood demon art as a human as you mentioned it, may i hear what she has?" "Nezuko has a blood demon art capable of burning only Demons, while it has no effect on humans. For my theory, if a human is poisoned by a Demon, Nezuko could possibly burn it all away." Says Tanjiro and Kagaya seemed interested in it "hm? Sounds like something which will serve the cause in the corps, either way it will startled the pillars." "As long as she can let them understand by showing the undeniable proof that it's harmless, then I'm sure they would accept her..other than, Shinazugawa and Iguro." Says Tanjiro and Kagaya seemed curious, "do you by any chance have issues with them?" "Not really, it's just that I'm picking up a scent of malice and hatred from them, and it's being aimed at me. And they don't seem to have any manners." Says Tanjiro with Kagaya sighing with Tanjiro saying "Oyakata-sama, If you won't be able to keep things in line, there will be consequences when it comes to cruelty being caused by Pillars deep through hatred and Malice." Kagaya smiles and says "I understand, I'll do what i can. I'll bring the young slayers in your estate while you're at it."

As Tanjiro in the Eclipse estate, as for so many slayers gathered in the back yard, with their purple bags and their swords with them, some talking to eachother. Until Tanjiro comes in, "Welcome in my fellow Comrades." They all faced to Tanjiro who he's in his green checkered Haori, Golden buttons uniform as the Slayers noticed. "It's Kamado!" "He's the Pillar of Sun now." "I was on a mission with him." "As was I." Tanjiro says "Alright, that's enough." The slayers all went silent as Tanjiro says "for now, You are under my supervision when it comes to training, of course. The training sure is harsh, But over time. You'll get used to it as you'll grow strong enough to survive and slay demons. I'm only doing this because the amount of demon population is increasing, our numbers will eventually drop because of that. I, Kamado Tanjiro, Pillar of Sun. And same goes for Tokito Muichiro, Pillar of Moon will be helping you all out."

"Uh... Excuse me, Kamado-sama. Where is the Moon Pillar?" Asked a slayer name, Murata. As Tanjiro replied, "He's in the swordsmith Village to receive his new sword, so he'll be off for a while. Leaving that aside, Welcome to the Eclipse Mansion, there's a hot springs nearby so make yourself comfortable while Dinner gets prepared. Training will start by tomorrow."

"Yes!" Says all the slayers, most of the slayers on the hot springs are feeling relaxed, "This is quite welcoming." Says slayer 1, "I wonder what kind of training shall we receive." Says slayer 2, "we are recieving Training from a pillar, keep in mind, not many pillars have tsugokus for certain reasons." Says Murata.
