The Demon Slayer Exchange Student

Leviathan, Avatar of Envy

???: "How about this? I vote for you to die, Mammon." 

Mammon: "D'ah...! Levi... Uh, l-listen up humans! This here is Leviathan, the Avatar of Envy. He's the third oldest of us, brothers. Since his name's sorta hard to say, you can just call him Levi! Okay then, let's move on." 

Levi: "Mammon, give me back my money. Then go crawl in a hole and die." 

Y/n: *Whispering* "That's harsh." 

Mammon: "Come on, I told you I'd get it to you! I just need a little more time. ...And you still want me to die even after I give it back? That's really harsh, Levi!" 

Levi: "You need a little more time? How much more?" 

Mammon: "A little more, okay?! A little more means a little more!" 

Levi: "You've been telling me that for the last 200 years, Mammon." 

Mammon: "Hey, no. It hasn't been 200 years! It's been 260! Get it right, Levi!" 

Y/n: "Yep. Now we need to go job hunting..." 

Y/n is trying to shove Mammon out of the room.

 Y/n: *Whispering* "You're digging a bigger grave" 

Levi: "Unbelievable. Seriously Mammon you're-" 

Mammon: "I'm what? Scum? Is that what you're gonna say?" 

Levi: "-you're a lowlife and a waste of space." 

Y/n: "Hey! You don't say things like that to your brother." 

Levi stares in shock. 

Mammon: "Huh?" 

Y/n: "You don't say those things about people who genuinely care about you. How much does he owe you?" 

Levi: "800,000 Grimm." 

Y/n: "Give me a month and I'll have it for you." 

Levi: "There is no way you're-" 

Y/n: "Give me a month." 

Levi: "Fine. If you don't?" 

Y/n: "I'll pay you double the amount when I can." 

Levi: "Fine." 

Mammon stares at Y/n in shock.

Levi: "What's the deal with this human you've got here with you? Are they your newest-"

 Y/n: "I'm the exchange student that is supposed to stay with you." 

 Mammon: "And they collect figurines." 

Levi: "Really?" 

Y/n: "Yeah, like Attack on Titan, Assassination Classroom, Death Note, Jujutsu Kaisen, and others. I probably won't know any of the ones you have though."

Mammon leaves. 

Levi: "Really?!"

Y/n slips through the door. 

~In the town~

Y/n is looking at her phone following the directions to Hell's Kitchen. A dark green and teal-haired male saw the human walking alone. He watched as the girl weaved through the crowds avoiding everyone as she stared at her phone. 

Diavolo: "How is she...? Never mind why is she out here alone?"

Y/n: "Left at the corner..."

???: "Excuse me."
