You arrived right at HUNTR/Xs tower! 

(Y/N): Hi girls! 

Rumi: (Y/N)?! 

Mira and Zoey: (blushing hard) Oh my God, it's (Y/N). 

(Y/N): Yes, it's me, and- Are you two staring at my abs? 

Mira and Zoey: (popcorn eyes) NO WE'RE NOT! 

(Y/N): Okay, that is cute. Either way, we ran into some demons, and I think you guys need to learn some Breathing Styles if we're going to beat these bastards. 

Rumi: Okay, fine. 

Zoey and Mira: Huh? 

Rumi: If we want to defeat them, we'll need all we can. 

Mira: WHAT ABOUT COUCH TIME?! 

Zoey: (crying) NO NO NO NO NO NO NO NO NO NO! 

(Y/N): It's okay, it'll be fine. 

And soon enough... 

You brought the girls over to train with the Hashira. 

(Y/N): Okay, it's time for the Hashira Training regiment! 

All three girls were in their bras and underwear, while carrying heavy rocks. 

Uzui: That's it, keep it up. You girls want to be flashy, then make sure not to drop those rocks! How's the stew coming? 

Hinatsuru: Almost done, Tengen! 

(Y/N): Man, this is bringing back memories. 

Later... 

They were doing some stretches thanks to Mitsuri. 

Mitsuri: This will help your flexibility a lot! 

Mira: That looks uncomfortable. How can you do that? 

Mitsuri: Because I push myself hard for everyone I love! 

(Y/N): Aww, that's our Love Hashira! Ain't she adorable? 

Much much later... 

They were sparring with Muichiro to increase their agility! 

Muichiro: Don't lose concentration; it will reflect poorly if you falter. 

Zoey: How fast is this kid?! 

(Y/N): He's the youngest Hashira, and the fastest. Still can't keep up with Zenitsu. 

And ... 

Gyomei had them withstand the flow of a harsh waterfall. 

Gyomei: Find your center; this will improve your muscles. Still, the pain is so sad. 

He was crying. 

Rumi: He's ... crying. 

(Y/N): Gyomei is a friend to all living things. You could say he's one of the gentlest Hashira. 

And finally... 

(Y/N): Okay, I think you two are ready for the next part! 

HUNTR/X: Next pa- 

You struck them all in the chests! 

HUNTR/X: AAAAAAAAAAAAAAAAAAAAGH! 

(Y/N): Now your breathing is different, but it'll help with Breathing Styles and Hamon. Don't worry, it'll go away after a while. I've dealt with this before, trust me. 

After more and more intense training... 

All three were exhausted. 

(Y/N): Okay, that should do it. You guys still got it! 

Muichiro: It seems so. 

Gyomei: All of them have grown so much, it's enough to make me cry. 

Mitsuri: Yay! Now we're all so much closer! 

Uzui: Damn fine women, (L/N)! Just as much as mine. 

(Y/N): Good, tomorrow we should have a sparring session with Rengoku, Tanjiro, and Inosuke, maybe even Zenitsu, if he behaves that is. Either way, I- 

You ran into Rumi, who got up. 

Rumi: (blushing) (Y/N), doyou think you can help me out a bit? 

(Y/N): Huh? 

Rumi: I really feel anxious about all this. 

(Y/N): Oh, we can't have that! Let's go and get some Bubble Tea and Ramyeon! 

Rumi: Alright! 

Much later.... 

You and Rumi were scarfing down all the Bubble Tea and Ramyeon you could get your hands on! 

(Y/N): Awww! Look at you go! 

Rumi: I'm feeling so much better now. Not even those stupid Saja Boys could make me feel hurt. 

(Y/N): Say, what are they up to? 

At the same time... 

The five of them were participating in a Game Show, drinking hot sauce, with Baby on top. 

Back with you and Rumi... 

(Y/N): Yeah, not important. 

Rumi: Thanks for accepting me like this, (Y/N). 

(Y/N): Hey, no problem. Why so insecure? 

Rumi: It's what my Master told us ...we're not meant to be different, we're supposed to carry the legacy for hundreds of years, and if we fail, the world is doomed. 

(Y/N): WHAT?! 

You grabbed a shotgun. 

Rumi: (Y/N), what are you- 

(Y/N): I just want to talk to her. 

Rumi: NO! Please don't go shooting her! 

(Y/N): But- 

Rumi: She taught us everything. I still owe her something! 

(Y/N): Okay, but I still want to sort something out with her! 

Rumi: Okay, fine. If you must. Just don't hurt her. 

(Y/N): (Sigh) I swear. 

Rumi: Thank you.
