The twins had a tour around the estate by Shinobu guiding them, and they now see Tanjiro on his rehabilitation training with Kanao, as for inosuke and Zenitsu witnessing it, Shinobu leading the twins in the training hall. The twins saw how the training is going as Inosuke saw them and saying "you there! Crow Twins! Fight me!!" "Inosuke No!" Says Shinobu and Inosuke stands down as Giichi says "So that's the boar head i heard about." "Why do you look like half-and-half haori?" Asks Inosuke, and the twins raised their eyebrow in confusion by such a nickname "Because we're his kids." Says Yumi and Tanjiro gained attention to them as well as Zenitsu in his joyful flirty tone "awww you are so cute, especially you there!" Faces to Yumi "I'm sorry, Are flirting with a 6 year old?" Asked Giichi while smiling in such a creepy way. Zenitsu got scared as he hides behind Tanjiro "YAAAA! Tanjiro, protect me this kid is as scary then Tomioka!" "Awww, how sad, how about i try and wipe that cowardness out of you?" Says Yumi in a pure yet creepy smile. "Aahhhhh! Tanjiro, Save meeee!-" Tanjiro Neckchops him into unconsciousness.
Later on, as Tanjiro and Kanao finished playing tag, Yumi asks "Oni-chan, ready for the game for no apparent reason?!" In excitement and Giichi smiling and raising his eyebrow "you need to ask?" Both twins made their way to the area as Shinobu says "Giichi, Yumi, this is a training hall!" "I know what i mean." Says Giichi as Shinobu says "that doesn't make any sense!" As both Twins started playing Tag with Giichi Chasing Yumi. And they are running around in quite the speed. The others are quite surprised as Tanjiro says "like i thought, the kind of scent they have is as similar to Kanao and the Pillars. They mastered total concentration breathing constant." "Did they?! At such a young age!?" Asked Shinobu in shock, she didn't realise it, until now. As they both stopped with tag and they pulled put their small sized wooden swords. "Ready to bring the Rain?" Asked Giichi "I might as well use an umbrella for that." Replied Yumi as they both started sparring. "Eeehhh, that's a bit too sudden." Says Shinobu who she can't process this. "Enough!" Yelled Aoi as both twins stopped and made their way towards her. "You had your fun, save it for later." Says Aoi as both twins says "Yes!"
3 days passed and Giyu is in a restaurant, after finishing his mission as he's eating salmon and Daikon, only for Mitsuri and Rengoku to show up. "Tomioka-san!" Says Mitsuri "Hey Tomioka! my buddy!" Says Rengoku. Giyu lays eyes on them as he raised his eyebrows "How's it been?" Asked Rengoku and Giyu sighs and hesitated, said "all good." "It's nice to hear, Say where are your kids? I wanna see them." Asked Mitsuri and Giyu replied "well, they are under Kocho's care since i was on a distant mission. And now i just came back." "It's nice to hear about your kids! Kocho's older sister is it? How did you get married?" Askes Rengoku "She got pregnant and got scared that i would be mad, but i gave her my promise to take responsibility as i ended up proposing to her next day. We hid her Pregnancy by having our master to have others think we'd be on a mission which would last one year, but in reality we are staying in my Teacher's old house. Urokodaki-sensei" "Shinobu-san's sister right? How was she?" Asked Mitsuri as Giyu replied "much Comparable to Tanjiro but far more mature, she was a fan of fairytales and legends. She was always patient, and she had a dream of a friendly demon as our ally." "So you mean that Kamado Nezuko was for?-" Asked Mitsuri "Yes, i kept her dream in check and found it unintentionally. And I'm still in hopes that Nezuko would be of great help, as she helped Rengoku." Says Giyu and Rengoku says "well, i now see what it is, protecting the innocent is our strongest priority..." "...No matter what nature you are at." Says Giyu as Rengoku says "you know, you remind me of my mother alot." "Congratulations, you are the second to realise it." Says Giyu and Rengoku got confused and asked "who was the first?" "Your father, He saw your mother in me when i was lecturing him harshly for being too neglectful towards you and your brother. As such he called me Ruka, i figured that it was your mother's name." Says Giyu and Rengoku realised as he asked "So that sudden change he had when i became a pillar was because?" "Yes, i had to do something, me as a single father, I don't tolerate neglectful nor abusive parenting." Says Giyu as he finishes his food and pays for it. "Tomioka, i don't know what to say. Thank you. You are just like my mother, wise, calm and patient." Says Rengoku "It is how it is, one must have responsibility depending on who you are, a Pillar, a Parent, Mentor or a leader." 'That's so moving, I just felt a chill running around my spine.' thought Mitsuri "well, i better get going, and see the twins." Says Giyu as he leaves, Waving them good bye.
Giyu in the butterfly mansion saw how the twins and the Caterpillar trio are playing around, The twins saw their dad as they ran and clinging into him "Oto-san!Your back!" Says Yumi as Giyu hugged them both with Shinobu and the trio witnessing, Shinobu feels hurt though since her love interest is all but taken already, even in death. "I hope you didn't cause any trouble." "No, we fell into it actually." Says Giichi, "that boar head called me a Crow girl and Oni-chan a Raven boy." Says Yumi and Giichi says "and that yellow haired kid seems to have no manners, giving no space to that demon girl." "Sounds normal then." Says Giyu "So, I've been thinking, since we've been on our own for a long time. I have made my decision." Giichi and Yumi asks "What kind of decision?" And Giyu says "we are staying in the Butterfly mansion, permanently." Leave the twins and Shinobu shocked to hear it and Yumi asked "Really? You mean?" "You said you wanna help injured slayers as best as you can, we are staying here for that." Says Giyu as Yumi says "Yaayyy!" "Well, i don't see why not." Says Giichi
"Cawww! Emergency Pillar meeting! Emergency Pillar Meeting!." Says Kanzabaru as Giyu faces them saying. "Guess I'm off for a little bit." "Take your time Oto-san." Says Yumi as Giyu leaves with Shinobu following Giyu "Aunty Shinobu." Says Yumi as runs to her and hugged her leg "please don't die, i know you are chasing the monster who took Oka-san away. I don't wanna lose you too." Shinobu tried to hold her tears as she says "but i...okay... I'll try." As she leaves the mansion.
As the Pillars are in the meeting room, as Giyu and Shinobu arrived late "we are here." Says Giyu as he and Shinobu arrived as Tengen smirking asked "what we you 2 doing?" "Making an agreement, I'm staying at the butterfly mansion permanently. For my kids to help injured slayers as they want to." Says Giyu and Gyomei says "such responsibility at a young age. I could already sense a strong soul in them." "It's true, it's been like this since Birth...when they were born...they never cried one single bit... unless it's joy or inner pain." Says Giyu as the room was silent as he then lays eyes on Sanemi as he asked "did you receive her letter?" "I did, and I'm sorry...tell your daughter i forgive her... I'll be Kanae's friend by being yours." Says Sanemi as Giyu then replied "forgiveness earned, right now...this meeting seems serious...the crows sounds startled." "It's true, my crow was so scared." Says Mitsuri and Rengoku asked "even mine, speaking of which, where's Iguro?" "He's late...i hope i didn't hurt him." Says Mitsuri and Shinobu asked "what happened?" "He and i had an argument about him hating Tomioka-san for literally existing around him...and i told him to leave..." Says Mitsuri as Giyu tilted his head and asked "are you hurt?" "So much, i never thought he'd be this possessive over me. Him preventing you from hanging out? I never felt upset in my life!" Says Mitsuri as Giyu sighs and says "I'm sorry about my daughter spilling the truth...she couldn't stand watching me being treated like an object of hatred...she wouldn't tolerate bullying and harassment as much as Kanae had the same thought...and believe me or not, Kanae wouldn't show Iguro any mercy for hurting me." "What do you mean by, watching you and him?" Asked Tengen
"Simple, both are good at hiding their presence from you all, and casually watch us train and spar." Says Giyu. "That's odd, but okay." Says Shinobu and Tengen asked "No offence but, Your the last person i heard about getting a wife." Giyu faces at him and replied "and?" "Well, i must say, you have a flashy taste for Women. So let me ask you this, How was she in be-" Asks Tengen as he smirks but stopped after Giyu stares at him in a dark aura, getting imitating and Shinobu getting pale while smiling "Uzui Tengen...We have a child here..." Says Giyu as he pointed to Muichiro as he is staring at nothing. "The ornament is now a Raven, a creepy raven." Mitsuri startled by the aura saying 'dear lord, he's so scary.'
until Ubayushiki Kagaya arrived with the kids saying "the master has arrived" as they all bow to him "good afternoon master, we pray for your health to be in condition." Says Giyu and Kagaya says "Thank you my child...on to the pillar meeting as it's urgent. I'm sure one of you is missing." "It is, Iguro is Missing! What happened to him?!" Asked Rengoku as Kagaya lost his smile, the pillars are shocked to see it as He says "Obanai has betrayed us." The Pillars were stunned to hear it, as Tengen asks "what? How? What happened?" As Obanai's crow comes in as Kagaya says "According to his crow, Obanai, during his mission. He kept complaining about him wanting to Kill Giyu and his kids, his Daughter at most." Giyu and The pillars was shocked to hear it "as such, he crossed passed with Upper moon 1, and he received and accepted the offering of joining them to get the strength to Kill The Tomioka family and Turn Mitsuri into a demon by force." Says Kagaya as Mitsuri was shocked to hear it, as Giyu holding his chest in. "So it's it then, He's obsessed with Kanroji, is he?" Says Sanemi and Shinobu was shocked the most and Giyu says "master, Kanroji-san, if anyone is to blame? I'm sorry for what my daughter did-" "No, it's not your fault. Nor your daughter's." Says Mitsuri as Giyu says "i understand, if it pleases you master, i may as well go off in finding him and take responsibility." And Kagaya says "he's no longer on site anymore. And plus, you are not to blame, you have your current priority. Chasing Upper moon 2, and having responsibility to the Kamado siblings." "Understood master..." Says Giyu as "although i must be honest about him, i don't hate him though, i just don't like how he badmouths me all the time...he goes off making excuses over me being arrogant every time I beat him in a sparring match." "Him threatening Tomioka-san for me inviting into events, talking to him, admiring him." Says Mitsuri as Muichiro says "i may not remember much, but i could remember myself seeing the snake being jealous to the Raven..." Kagaya sighs, "our pillar has been lost" "What's going to happen if he spills information about you to Kibutsuji?" Askes Shinobu as Kagaya says "that is something which is already handled with, as you must know, when you became a demon slayer, you receive a curse, when you get turned into a demon, the curse will trigger into erasing the information about our location, therefore, he won't even remember his own estates location." "We shall stay alert, incase anything happens." Says Giyu as Kagaya says "Thank you my children, meeting dismissed." As the master leaves with Giyu turning to see Mitsuri as he says "Kanroji-san, i..." "No, it's not your fault...i just can't believe how he could be this obsessive towards me." Says Mitsuri whos crying, "and selfish at the same time...just to put it simple, he doesn't even care if he hurts others. Unless its you or Kaburamaru." Says Giyu.
Later on, Giyu on his way to the Butterfly mansion, as the news spread about The Pillar of snake, betraying the organisation. Tanjiro has received the book of sun breathing of Rengoku Shinjuro, the former flame pillar. After that Tanjiro has been training hard, as Zenitsu and Inosuke are. With Giyu Training them as harsh as it gets. Zenitsu though having such cowardness, Giyu is still doing his best. Meanwhile Tanjiro and Kanao are in the training hall, sparring with wooden swords while Inosuke and Zenitsu witnessing it until. "Hashibira-san." Says Yumi as Inosuke and Zenitsu faces to her holding a sleeveless shirt of the uniform. "I heard that having the uniform kills your senses so, i requested the tailor to make just an ordinary shirt for you. Hopefully this has no effect to your sharp senses. Think you can try it out?" Says Yumi as she smiles as Inosuke doesn't respond but takes the shirt as he wears it, no sleeves and it's unbuttoned entirely, he holds the insides of the shirt to where the buttons are "So, how does it feel?" Asks Yumi as Inosuke laughing and saying "Muaahahahah! This feels much better. I can't feel my senses getting blocked. The king of the mountains is greatful to you Crow Girl!" "No need to thank me, I'm just doing what i can. What i do best, assisting the slayers." Says Yumi and Inosuke says "The great Lord Inosuke insists! Here you go!" As he drops a bunch of acorns on her head. Yumi was left confused as she asked "what was that?" "It's a gift, to those of whom Lord Inosuke is thankful with." Says Inosuke as he pointed at himself with his thumb as Yumi chuckled as she picks them up. "Is that so? I'll treasure it as a nice gift. King of the Mountains." Says Yumi as Zenitsu seems mad and jealous 'why do you and Tanjiro receive attention from girls when i don't?' as the voice of Giichi says "seems like you lacking manners is much more than i heard." Zenitsu saw how he's sitting next to him, "ghaaaaaa! That kid's a Monster!" 'I think i know exactly how to get you into a good Stamina' thought Giichi as he says "you are coming with me, Hashibira-san, can you come with me? I could use a little help." As Inosuke says "Well, since the crow Girl has brought Lord Inosuke fabulous Gift. The king of the mountains shall return the favour by helping the raven!" Giichi smiles while raising his eyebrow as Zenitsu is outside as well as Inosuke but further away with 2 wooden swords as Inosuke asked "Am i Sparring with chenitsu?" "No, It's as Simple as it gets. Hashibira-san, make sure he keeps running as fast as he can until his bones shatter. By chasing him, and don't hold back, if he slows down? You land a bunch of blows with your wooden swords to make sure he runs." Says Giichi as Zenitsu yelled "Gyaaaaa!? Whaaatttt!?" "Muahahahaha, it's Easy then!" Says Inosuke as Giichi yelled "Your training starts, Now!" Inosuke starts chasing him as Zenitsu starts running from him "Come here Monitsu!!!" "Gyaaaaaaaaaaa! Save meeee!" As they kept running around the garden of the mansion. "Hashibira-san! If you manage to put on a good Training, i might bring lots of Tempura for dinner Tonight!" Yelled Giichi as Inosuke yelled "MUAHAHAHAHA! TEMPURA! HERE I COME!!" as he speeds up "Yaaaaa! No no! Tanjiro! Save meee!!" Yelled Zenitsu as Yumi, Tanjiro, Kanao, Aoi and the Caterpillar Trio witnessing this by sitting on the living room "is this supposed to help Zenitsu in training?" Askes Tanjiro and Giichi replied "In a way, it's just stamina training. Unlike You and Inosuke, He lacks motivation to train. I might know how to fix this guy up." "TANJIRO! SAVEEEEE MEEEEE!" yelled Zenitsu as Tanjiro says "Sorry, no can do! It's for your Training." As Inosuke yelled "Come here you Coward!" "Gyaaaaaaaaaaaaa!" Screamed Zenitsu as the voice echoed to the entire estate.
