Team RWBY was enjoying a weekend out in Vale proper... With Jaune behind them, carrying several bags and boxes of purchases.
Ruby: "Are you sure you're okay, Jaune?"
Jaune: "Yeah! Yeah, I'm fine. This is nothing!"
Ruby: "We-We are making you carry a lot though."
Yang: "You okay, Jaune?"
Jaune: "I said I was fine. I got lots of practice for when my sisters went shopping."
Weiss: sighs "Why exactly are we using him as our pack mule?"
Jaune: "Well I had to be here anyway."
Blake: "Plus, my fiance should be with us in public if my Aunt shows up and asks questions."
Yang: "You mean my fiance?"
Ruby: "He's not either of your fiance's! Stop acting like it!"
Weiss: "Ugh... Why did you have to start this, Blake?!"
Blake: "I panicked!"
Weiss: "That excuse got very thin long ago!"
Jaune: sighs "Guys, no matter how traditionalist your parents are, they can't force us to get married, right? My Nana will stop anything from happening. She's still got connections, so don't worry about it."
Yang: "All right... So we'll stick with you being my boyfriend from now on, huh?"
Jaune: "Huh?!"
Blake: "That's hardly fair, Yang."
Yang: "HEY! At least I asked!"
Ruby: "You can't just-just ask him like that-!"
Yang: "Wanna be my boyfriend, Jaune?"
Jaune: "Oh, well-"
Blake: "He should be mine! Aunt Yoruichi might be anywhere!"
Weiss: "That's not a compelling reason to date you."
Blake: "There are many compelling reasons to date me! Besides, his tastes have to have improved if he stopped going after you!"
Weiss: "Why you-!"
Blake and Weiss continue to argue, as Jaune, Yang and Ruby look exasperated.
A blue haired young man turns and stares at them. He gasps, and charges right for Yang.
???: "You!"
Yang: "Eh? Me?"
???: "Your beauty, your poise, your confidence-Yes! You're perfect! Please, tell me: Would you like to pose nude for me?"
Yang: bright red, hair burns gold and eyes glow red "EXCUSE YOU?!"
Jaune: "AH! YUSUKE!"
Jaune drops the packages and quickly goes up between Yang and the blue haired boy.
Jaune: "Yang? Please don't kill him."
Yang: "Why not?!"
Yusuke: "Oh! My apologies, I got a bit too excited-"
Yang: "You-!"
Jaune: sighs "This is Kitagawa Yusuke. He's a friend of my cousin from Fuujin. He came here to watch the Vytal Festival, and I was going to meet him. He's an artist-A really good one! Show them, Yusuke!"
Yusuke: "Certainly."
Yusuke pulls out an easel, canvas and paint set and immediately goes to work, painting almost frantically. He then finished with a flourish, and turned the canvas around to show a beautifully rendered painting of RWBY and Jaune.
Ruby: "OH WOW!"
Weiss: "In-Incredible!"
Yang: "I, wow..."
Blake: "Amazing!"
Yusuke: poses "Thank you. I was able to find my inspiration under threat of mortal peril. In that moment, all else slips away but the need to create and bring forth my vision into the world."
Jaune: exasperated "You could have just showed them your portfolio."
Yusuke: "Futaba thinks I'm much more convincing when I act."
Jaune: "Is... She here now?"
Yusuke: "No, the rest of our group will arrive in a few days. I just wanted to get here sooner to see the art scene. It was wonderful to meet you! May I come to Beacon to do sketches and paintings?"
Jaune: "I uh, sure! I'll get you a visitor's pass."
Yusuke: "Excellent! And ladies, if you are interested in posing for me-"
Yang: "Mayyyybe wait a bit before you ask that again?"
Yusuke: "... Ah. Yes. Forgive me, I do tend to forget normal social conventions. Oh! Is that an original Lassiter painting?"
Yusuke heads off, entranced. RWBY and Jaune watch him go.
Weiss: "... Is there anyone normal connected to your family?"
Ruby: "You do realize we're connected to him, right?"
Weiss: bright red "YOU-!"
Ruby and Weiss argue. Yang grins and sidles up to Jaune's side.
Yang: "Ya know, if you wanted me to pose nude for you, I might be able to bare it, Jaune."
Jaune: blush "Yang!"
Blake: "Please. I'm a superior nude model."
Jaune: "Blake!"

Yes, it's Yusuke from Persona 5. And naturally Jaune's cousin is that other harem protagonist. Ren Amamiya aka Joker. It's a way to introduce Fuujin, the Japan analog, into the fic. And now you know why Jaune can handle so much eccentricity-Between his family and friends, there's a LOT to deal with.
