You chased Zenitsu into the backroom, where two guards stopped him. 

Guard: Hey, you can't go in there! 

Zenitsu: OUT OF MY WAY! I'M GOING TO MEET THOSE CUTE GODDESSES! 

(Y/N): NO! 

You punched Zenitsu into the ceiling! 

(Y/N): I'm sorry about my friend, he's an idiot, but he's a good guy. Trust me. 

You showed a backstage pass, and Tanjiro appeared with a bow. 

Tanjiro: I apologize on behalf of my friend's behavior. 

Inosuke: Hey, which one of you can fight well? 

Guard 2: What is up with him? 

(Y/N): He was raised by boars. 

Guards: Oh, that makes sense. 

Inosuke: Shut up! Can you do this? 

Inosuke began to bend his body.

Play from 0:13-0:20... 

Guard: Just please, don't cause any trouble. 

(Y/N): Yeah, hang on. 

You knocked out Inosuke and started to carry in both him and Zenitsu. 

(Y/N): Trouble will be caused the moment these two dumbasses wake up. 

Tanjiro: SORRY! SORRY! 

He kept bowing as you both entered. 

(Y/N): Hello ladies. 

Mira: Wait, how did you get in here? 

(Y/N): Backstage passes. 

Zoey: Oh, good, you're fans? 

Rumi: Wait, Bobby never mentioned that. 

???: Uh, maybe I did? 

Nearby was the manager of HUNTR/X!

Bobby (The Manager of HUNTR/X and kind of a surrogate father! He has no clue about the Demon Hunting, but handles the band stuff! Pretty much stressed out 24/7! Voiced by Ken Jeong (Who played Mr. Chu in the second Goosebumps movie!)) 

Inosuke woke up. 

Inosuke: HUH?! Hey, who is that guy? 

(Y/N): Okay, you better go, the moment he thinks you can fight, he'll want to fight you. 

Bobby: WHAT?! EEE! 

He ran out. 

Zoey: He has a pig mask on his face! 

Tanjiro: Again, I'm sorry! 

Mira: What, was he raised by pigs or something? 

(Y/N) and Tanjiro: Yes. 

Zenitsu then woke up. 

Zenitsu: OH MY GOD! YES! YOU ARE SO BEAUTIFUL! 

He began to hold Rumi's hands. 

Rumi: Uh ... 

Zenitsu: PLEASE! I ASK THAT YOU MARRY- AGH! 

You slammed a folding chair onto Zenitsu's head. 

(Y/N): He's a pervert who can't control himself. Either way, want to take a selfie? 

HUNTR/X: Uh ... yes! 

They all started taking selfies with you, and soon you both left. 

Mira: Okay, couch time. 

Zoey: YES! 

Mira and Zoey: COUCH! COUCH! COUCH! COUCH! COUCH! COUCH! 

They both fell on top of a nearby couch and just took it all in. 

Rumi on the other hand, saw a paper that said, "It's okay, we know your secret. We can sort this out. (Y/N) (L/N) and Tanjiro Kamado." 

Mira: Hey, Rumi, are you going to join us? 

Rumi: Yeah, hang on. 

At the HUNTR/X Tower... 

Mira and ZOey were watching turtle videos. 

Mira: Oh, I love turtles! 

Zoey: Me too! What about this? 

https://youtu.be/CwR3V19_xOA

Zoey SO CUTE! 

Mira: I have never seen something so cute in my life! 

Rumi walked in starting at the note. 

Rumi: Hey, do you ever think there would be a reason for someone to help us get stronger? 

Mira: Huh? 

Zoey: Hey, we've been keeping that barrier on this world for so long! We're awesome! 

Mira: Exactly. 

Rumi: I know, it's just ... nevermind. I just got finished taking my bath, so I'll relax. 

Zoey: Say, how come you never take baths with us? It should be a group thing. 

Mira: Yeah, it's always just us. 

Rumi: I ... 

She thought about the marks that were on her body. 

Rumi: Never mind, let's just watch some turtle videos. 

Mira: That's more like it, girl. 

Zoey: HECK YEAH! 

The next day... 

(Y/N): Zenitsu, what are you staring at? 

Zenitsu: Art. 

(Y/N): What ar- Oh! 

https://youtu.be/yebNIHKAC4A

Tanjiro: That was very beautiful. 

Inosuke: Lame, I really don't get it whatsoever. 

(Y/N): An uncultured pig like you wouldn't understand. 

You were tearing up. 

(Y/N): I agree, Zenitsu, that was art. That's when you smelled some food and- 

???: UMAI! 

(Y/N): Wait, was that- 

Tanjiro: Mr. Rengoku? 

Rengoku was seen nearby, eating some Bulgogi from a stand. 

Rengoku: UMAI! 

Zenitsu: What is he doing here? 

(Y/N): I get the feeling Najimi may have sent him. 

Rengoku: Ah, Young (Y/N), Young Kamado, Boy in Yellow, Young Boar, I've been waiting for you four. 

(Y/N): When did you get here? 

Rengoku: Some of the Hashira arrived last night, after the report concerning that you suspect those young Demon Slayers- 

(Y/N): Hunters. 

Rengoku: Yes, well, you say you feel like one of them is a Half Demon? 

(Y/N): Yeah, and also- 

You looked around. 

(Y/N): Please don't tell me Sanemi is- 

Rengoku: Rest assured, Shinazugawa isn't here. 

(Y/N): Good, that guy is brutal when it comes to that stuff. 

Sanemi's hatred for demons was something he always took too far. 

Tanjiro: Mr. Rengoku, it is a pleasure to work with you again! 

Rengoku: HAHAHAHAHAHAHA! Yes, I admire your spirit today, Young Kamado! 

You then saw Rumi. 

(Y/N): That's her. 

Rengoku: This Rumi girl, you're certain she is half demon? 

(Y/N): Yes. 

Rengoku: I see. 

(Y/N): Alright, I'm going to talk to her, and- 

???: YUMMY! 

Right next to Rengoku was Mitsuri, eating all the food she could get her hands on. 

Tanjiro: Ms. Kanroji, too? 

(Y/N): (blushing hard) M-Mitsuri. 

Mitsuri: (Y/N)! 

She gave you a big hug, nearly crushing you! 

(Y/N): AGH! MITSURI! TOO TIGHT! 

Mitsuri: Oh, I'm sorry! How are you? 

(Y/N): Wonderful, thank you. God, why does she have to be so damn adorable? Here, in case you want more- 

You gave her more money for her to eat more. 

Mitsuri: AWWWW! YOU'RE SO SWEET! 

She gave you a big kiss as you walked off to see Rumi. 

(Y/N): I'll be back. 

Zenitsu: Just what is he going to do? 

Rengoku: Young (Y/N) will simply use his iconic charm. 

Soon... 

Rumi: What can I do? What if I can't sing anymore? 

She began to feel that her voice was giving out. 

(Y/N): (singing softly) Shine like rainbows ... you'll shine like rainbows. 

Rumi quickly summoned her weapon. 

(Y/N): WHOA! Easy! 

Rumi: Oh, it's you. Are you (Y/N)? 

(Y/N): Yeah, loved your newest video. That was magical! 

Rumi: (blushing) Th-Thank you. 

(Y/N): Listen, my friends and I know, you're a half demon. 

Rumi: How do you- 

(Y/N): Your chi is a mixture of human and demon, and you smell like a demon. 

Rumi: Smell? 

(Y/N): My friend Tanjiro is a Demon Slayer who is very skilled at tracking demon scents. 

Rumi: You're part of a group of Demon Slayers? 

(Y/N): Yeah, the Demon Slayer Corps, we dedicate ourselves to protecting others from demons. You see, well, Tanjiro's sister, Nezuko, was transformed into a demon, and we had to fight a demon named Muzan in order to turn her back.  We can help you. Come tomorrow to the hotel we're staying at. 

Rumi: Wait, what kind of people are- 

(Y/N): We're on your side. You're not the only one who's suffered through pain. 

You then walked off. 

Meanwhile... 

???: WHY?! WHY, AFTER ALL OF THESE YEARS, CAN'T I BREAK INTO THAT WORLD?! 

Gwi-Ma (The ruler of the Demon World! He was blocked off after the first Demon Hunters created the Honmoon Barrier, blocking him off! Has tried desperately to break through!) 

One demon stood before him. 

Gwi-Ma: Tell me Jinu, what is your plan? 

Jinu (Servant of Gwi-Ma! He secretly hates his master, and feels regret for leaving behind his family to live a life of comfort!) 

Jinu: I have the perfect plan to control those masses. 

He was joined by other demons. 

Jiu: A Boy Band. 

Gwi-Ma: Boy ... Band? 

Jinu: Trust us, we'll get the job done. 

Meanwhile... 

Rumi led Mira and Zoey to the hotel you were staying at. All three of them wore disguises. 

Mira: You're telling me, he can just help us with our voices? 

Rumi: Well, that's what he said. 

Zoey: That is just so cool! 

Mira: I would rather trust a doctor. 

Rumi knocked on the door as- 

Inosuke: SURPRISE ATTACK! 

He burst through! 

HUNTR/X: HUUUUUUUUUUUUUUUUUUUUUUUUUUUUH?! 

Inosuke: HAHAHAHAHAHAHAHAHAHAHAHA! HOW WOULD YOU LIKE A- 

???: Inosuke, now that's not the right way to greet someone. 

Inosuke: AGH! 

Shinobu was behind him. 

Shinobu: You have to be cordial and polite. Hello and welcome, come this way. 

Rumi: Are you one of- 

Shinobu: My name is Shinobu Kocho, and I am one of the Hashira of the Demon Slayers. (Y/N) is one of us.
