"Damn what kind of dust should I get this time". Y/N muses as he hears someone walk up behind him and clears their throat causing Y/N to turn around and see a white haired girl. "Oh sorry Weiss Schnee didn't notice you were there my bad". Y/N then steps to the side as Weiss steps forward and asks. "How do you know who I am"? Y/N chuckles a little as he replies. "Well my parents run a dust store so they kind of keep up to date with the SDC". Weiss nods as Y/N asks. "Since I have a dust expert here can you help me pick out some dust for my weapon, I'll buy you a coffee later"? Weiss shakes her head with a small smile on her face as she replies. "Sure". 

Blake Belladonna 

"What to read today"? Y/N ponders out loud while wondering through the Beacon library trying to find something to read that isn't a textbook. Just then a book catches your eye however as you reach for said book another hand reaches for the book as well, Y/N turns to see a girl with black hair and a black bow on her head. "Oh sorry I look for another book". Y/N says as the girl nods her head and replies. "If you're looking for a book, I could give you a recommendation".

"Having fun there boys? Seems a bit cowardly of you all to pick on one guy". The guy who punched Y/N just scoffs and replies. "Whatever bitch, let's go guys this just isn't fun anymore". As the group of people leave Y/N gets to his feet and turns to the girl and says. "Thanks guess I owe you huh". The girl shakes her head with a smile and replies. "Your good, the name is Yang what's yours handsome". Y/N gives Yang a smile as he replies. "I'm Y/N, here lemme get you drink to say thanks".

"Told you here ears were real". A tall boy with brown hair says pulling on the bunny ears of a girl with long brown hair and brown eyes, as tears begin to form in her eyes suddenly the pain of her bunny ears being pulled stops as she then sees the boy stumbling backwards. "Get lost Cardin"! Y/N yells as Cardin rushes towards Y/N however Y/N quickly hits Cardin with a right cross knocking him out, Y/N then turns to Cardin's teammates who just run away. "Are you okay"? Y/N asks turning to the bunny girl who nods and replies. "T-thank you m-my name is V-Velvet". A blush begins to form on Velvet's face as Y/N replies. "I'm Y/N good to meet you Velvet". 

Coco Adel 

"What one to buy"? Y/N ponders out loud as he then sees someone walk next to him and says. "I'd say get these".

Y/N jokes as the girl laughs and replies. "You're welcome, I'm Coco by the way". Y/N responds. "I'm Y/N".

"Put those weapons away now"! The group of people flinch as Vernal then adds. "Get out of here before I tell Raven you guys were about to kill a fellow member".

"Thanks for the save Miss". The woman walks over to Y/N and asks. "The other dead bodies around here and further behind are your doing"? Y/N nods and answers.
