Here is the translation:

Shinobu: Hello~ You there~. Yes, that’s right. I’m talking to you. You’re the new recruit that joined last week, right? Nice to meet you, I’m the Insect Pillar, Kocho Shinobu. And this guy here….
Giyu: I’m Tomioka Giyu.
Shinobu: I’m sure you’re already aware but you’re gonna learn everything about the Demon Slayer corpse with us today. If there’s anything you don’t understand, don’t hesitate to ask us questions, okay?
Giyu: Let’s go
Shinobu: Geez~ That’s not good, Tomioka-san.
You should say “Nice working with you, today” or greetings like that first… It’s because you’re like that..
Giyu: What?
Shinobu: No, it’s nothing. Then, let’s go. Once again, it’s nice working with you today.
Shinobu: This is the Demon Slayer Corp’s
Headquarters. This is the place where the Demon Slayer Corps leader, Oyakata-sama is. We also have a lot of materials we accumulated over a long period of time. Please review the materials carefully and use it as a reference in the future.
Giyu: When you joined the Demon Slayer Corps, you received a Nichirin sword, right? There are different types of Nichirin sword, it’s also called a color changing sword, the bands are different colors depending on its owner. The hashira’s sword has a “destroyer of evil” engraved on it as one of its features.
Shinobu: If I remember correctly, your nichirin sword has a pretty blue color, right, Tomioka-san?
I fight with my nichirin sword that has a poison to kill demons on it. I’m a pretty amazing person that can combine various poisons, from the gentle kinds to the lethal kinds, you know.
Giyu: Depending on the swordsman, each nichirin sword has its own quirks. First, you have to train everyday and be sure to feel the knife and let your hands get used to the feeling. So that you can swing that sword to your hearts content in case of emergency.
Shinobu: Each of the swords are made with care by the swordsmith, so be careful not to lose or break your sword, okay?
Shinobu: That’s right, I’ve been meaning to ask you this but… why did you save Kamado-kun’s younger sister, Tomioka-san? Our work as a Demon Slayer is to kill demons. Obviously, you should kill the younger sister who has turned into a demon. Same for the letter we received from Urokodaki-san during the trial, saying you’ll commit harakiri once the younger sister (Nezuko) harms a human…
Giyu: I’m keeping someone who became a demon alive, that’s all there is to it.
Shinobu: You’re not answering my question, you know, Tomioka-san. Once again, why did you save the younger sister?
Giyu: “Nezuko is different. Nezuko won’t eat humans”
Shinobu: Eh?
Giyu: That’s what the older brother said while protecting his younger sister. In fact, even though the younger sister turned into a demon, she threw herself to shield her human older brother. That’s all there is to it.
Shinobu: I still think your words aren’t enough but in other words, you felt something different from her from the others, is that what you mean?
Giyu: Yeah
Shinobu: Hehe, you’re unarticulated as usual, Tomioka-san. Let me hear more about this the next time we get time together.
Shinobu: To all new recruits that gathered here today including you, We, the hashira, are thinking of giving you some words. Now, Tomioka-san.
Giyu: I’m fine.
Shinobu: Do your job, okay~ Tomioka-san~
Giyu: Strive for discipline during training. If you continue doing that, you’ll be able to see things.
Shinobu: A swordsman can bring out his full potential by doing “Total Concentration Breathing”.
If you master the total concentration breathing, maintaining this all time, your physical ability will rise drastically. From now on, we hashiras are planning to conduct a training for the new recruit, would you like to join too?
Giyu: You don’t know when or where demons are hiding at any time. It’s not unusual to hear stories about what was rumored to be a man-eating bear is actually a demon.
Shinobu: You’re right, I hear those kinds of stories a lot.
Giyu: Demon tends to hide in those ugly rumors.
As a new recruit, you will likely take works where you have to investigate and confirm such rumors.
Shinobu: Tomioka-san sucked at speaking, he got the police called on him for walking about in town with a sword.
Giyu: That’s not true
Shinobu: Hehe, I don’t know about that~ It would be better if demons and humans just got along.
Now then, there’s a special technique called
“Blood Demon Art” used among demons to fight.
First of all, it’s important to figure out what kind of ability your opponent is using.
Giyu: During missions, you’ll be fighting demons with various kinds of blood demon art techniques but don’t panic, panicking will disrupt your breathing techniques and it breeds hesitation in your swordsmanship. Anyway, keep your cool and be conscious. It’s a long way to go.
Giyu: The one who has the power to turn humans into demons, the progenitor of all demons, that demon’s name is Kibutsuji Muzan.
Shinobu: Kibutsuji has demons who report directly to him called the Twelve Kizuki. The twelve kizuki received a large amount of blood from Kibutsuji and they have powers incomparable to the other demons. Defeating someone from the twelve kizuki, or killing 50 demons are the requirements given to become a hashira.
Giyu: The twelve kizuki consists of 6 upper rank demons and 6 lower rank demons. It is said that the composition of the upper rank demons has not changed for nearly a 100 years.
Shinobu: Even so, we have responsibilities, isn’t that right, Tomioka-san?
Giyu: Yeah. We will definitely defeat the twelve kizuki and bring Kibutsuji Muzan down, that’s the mission of the Demon Slayer Corps, the mission of all swordsmen.
Shinobu: That’s right, how about we try some practical training using what we have learned so far? Correct your posture and do the total concentration breathing. Take a deep breath, exhale… And inhale… Yes that’s right, you’re doing it right. Please concrete and catch your breathing.
Giyu: Imagine that there’s a demon right in front of you. It is impossible to cut down your enemy as it is protecting someone with such weak determination.
Shinobu: Do your best! We’re here watching right beside you. I’m rooting for you the most!
Shinobu: In the past, Tomioka-san and I were ordered by Oyakata-sama to head in the mountain where a certain demon lived. The name of the mountain is….
Giyu: It’s Mt. Natagumo. It is a spider mountain ruled by a demon named “Rui”, a demon with the title of lower rank 5 of the twelve kizuki, and the demons claiming to be his family.
Shinobu: I met a cute young lady demon. She was being forced into submission and she was asking me to help her, so I did help her and yet..for some reason things did not go well…
Giyu: I cut off the head of a huge demon beyond human size and the lower rank 5.
Shinobu: Oh my~ did you forget that you interrupted me with my slaying?
Giyu: Eh?
Shinobu: At that time, I really thought you were violating the corps rules, Tomioka-san.
Giyu: Ugh…
Shinobu: How about you say something for yourself? Well then, how about we continue the story about the Mt. Natagumo.
Giyu: It’s the story of the night when the young members poured out their breath with all their might.
Shinobu: There, thanks for your hard work for today. Today’s mission is over. From here on, your story as a demon slayer swordsman will start, when that happens, I’ll be happy if what happens today will help you out even just a little.
Giyu: Well then, I’m leaving
Shinobu: Geez~ Tomioka-san!
Giyu: Before long, the crow that will deliver the order will arrive, before that make sure to rest and wait. Once the mission starts, there will be times you will feel frustrated, and times you will feel so distressed you want to scream. Even so, keep looking forward. Your strong strong and pure heart will become your driving force to move your hands and feet. Someday if we meet each other again on a mission, when that time comes then…
Shinobu: …..
Giyu: What?
Shinobu: Nothing, how should I put it….I think it’s unusual for you, Tomioka-san.
Giyu: You’re the one who told me, right, Kocho?
That greetings are important.
Shinobu: My~ hehe you’re really an interesting person, Tomioka-san. Once again, today’s mission is over. I can’t wait to meet you again and see you have improved someday.
Giyu: Take care.
Kimetsu Academy
Giyu: It’s a new semester. Everyone, go take your seat in front of the blackboard. There are a lot of transfer students after all, let’s the introduction right away. From your seat, raise your hand and introduce yourself, tell your name right away!
Shinobu: You’re scaring the transfer students, Tomioka-sensei.
Giyu: Go back to your own classroom, Kocho.
Shinobu: I was worried that you’re overdoing things again so I came to watch and see.
Giyu: The morals of the class are disorderly.
Piercings, poor clothing, blonde, coming to school with a piece of bread in their mouth. I won’t turn a blind eye for such violations of school rules from the start of a new semester. I intend to deal with this decisively!
Shinobu: Geez~ this is the reason why there are complaints about you being too spartan, you know.
Giyu: !
Shinobu: I know, If you like Mr. Transfer Student, since it’s your first day transferring, would you like to take pictures with me? I think that would be a good memory.
Giyu: I’m not…!
Shinobu: “I’m not hated” Please give me another reply than that, okay~ sensei~
Giyu: !!
Shinobu: Hehe, you cut off my club’s budget so l decided to tease you a little. Would you like to take pictures with me and the transfer student, Tomioka-sensei?​​​​​​​​​​​​​​​​

This is too cute!!! I am loving their dynamic here. Her voice is so soft when she teases him. Him listening to her is so sweet too. I love it so much.
