So, I had this idea after watching RWBY and playing DMC4. What if Jaune was Nero? And then someone started doing it with a story called Devil Arm which might get changed to Grimm Arm but I'm gonna do mine damnit! So without further a do, like this story! Also I will be using the DMC4 soundtrack for Jaune's music and headphones if indicated.

Chapter 1: Kid with a Cast, and a Giant Sword

The airship to Beacon Academy was bustling with excitement! As the airship, everyone was on their feet gazing at the massive school, except for one. A student near the back with a cast on his arm in a sling and bleach white hair. His head down he listened to music with his headphones, tapping his foot with the beat. (DMC4 the time has come) His name was Jaune Arc. He wore a long, black-purple and red coat with his family's due gold arc insignia sewn into both shoulders. He also had on a red zip-up hoodie/vest underneath his coat, a navy muscle-shirt beneath that, and a pair of dark blue pants. On his left, uninjured hand, he had on two rings. One on his index finger with the Arc insignia and the other on his ring finger with a rose design. The same rose design stayed prevalent on his belt buckle and coat clasp and buttons. (Nero's outfit)

He looked up and at the excited student, still lightly bobbing to his music. He dismissed the excitement entirely, as the awe of such things had become something hackney for him. He stood up and exited the ship as the docked. He tried to drown out the noise as he exited the ship among the tsunami of students, no one paid him any mind but he couldn't eliminate the noise. He groaned and pulled of his headphones and looked around.

"So, this is Beacon," He muttered to himself. "Kind of underwhelming."

Suddenly, something exploded behind him, making him spin and reach for his gun, Blue Rose, before stopping short.

"Unbelievable!" the girl in white cried. "This is exactly what I was talking about!"

She continued to rant and yell at the girl in the red hood. A girl with a black bow and clothing style walked up said some words that pissed off the girl in white before she left. Red tried to talk to black but she had vanished before hand. Red fell back, obviously depressed. Jaune shook his head and sighed before walking up the girl, casting a shadow over her. He held out a hand.

"Need a hand?" he asked and pulled her up.

"Thanks. Hey! Aren't you that guy that got hit by someone's case and didn't even flinch!" She exclaimed. Jaune sweat dropped.

"I got hit by a case?" he asked, not recalling that at all.

"Yeah you were asleep and then the ship hit some turbulence and someone's suitcase fell and hit you right in the face! You didn't do anything, we thought you might have been knocked out but no one could find a mark on you! Oh! I'm Ruby Rose by the way!" She said at the speed of light.

"Hu, well I'm Jaune Arc," he introduced himself as they began walking. "I'm honesty surprised that's what you noticed, not my white hair, cast or my giant ass sword on my back."

"Wait!" Ruby cried before she gasped and screamed like a fan girl. "OMG! That is soooo cool! What is it? What can it do? Can it shoot lasers? I bet I shoots lasers!" She was bouncing up and down, back and forth before Jaune grabbed her and held her down.

"Wow, calm down!" He said before drawing Red Queen. "this is Red Queen, my blade of choice, complete with insane resistance and an Exceed feature."

"Exceed?" Ruby asked. Jaune chuckled and but Red Queen on his back, magically staying in place. "I'll show you later maybe, we better get to the orientation."

"By the way," she began. "Do you know where we're going?"

"I was following you more or less," he admitted. "I think it's this way." He paused. "Race you!" and took off.

"Hey!" Ruby cried out before bursting after time, instantly getting in the lead. "Ha ha!"

"Hey no fare!" Jaune cried as he chased after her.

Eventually they got to the meeting hall and walked in.

"Oh, there's my sister, I'll see you later Jaune," Ruby said and left for her sister.

"Ok, see you round," Jaune began walking off before he realized. "Aw crap! No where am I gonna find a nice, quirky girl to talk to?" Jaune threw his hand up and walked off. He suddenly heard Ruby scream. He turned and saw the girl in white was chastising Ruby again.

"Yeah! And we can brad each others' hair, and talk about cute boys like tall, bleach and….crippled over there," she pointed at Jaune. He glared at the heiress at the comment as she coldly rejected Ruby.

He heard Goodwitch directions on sleeping arrangements before walking towards Ruby and her sister. As he passed the girl in white, he sharply elbowed her with his cast, making her drop to her knees.

"Cast's on my arm not my ears bitch," he hissed as he walked past. One could feel the anger from him. He didn't really have a choice on the whole cast thing. He couldn't show his other arm. The world would reject him worst than Faunus. As everyone reached the main hall after putting their weapons and armor away in the lockers, he took a detour to the men's room and hid in the stall as he removed his cast, jacket, hood and shirt. He looked at his glowing blue and red arm before putting the glove back on and carefully replying the cast and resting it in the sling, hopping it didn't fall out or his cast comes loose over night. He grabbed his clothes, but pat on his headphones and left for the main hall.

Meanwhile with Ruby, she was busy writing a letter before Yang decided to butt in.

"Aw you're writing a letter, how cute!" Yang purred.

"Yang!" Ruby cried, not happy with her older sister's teasing.

"So, who's it to?" Yang asked.

"To my friends back and signal! I can wait to tell them all about Beacon!"

"Yeah but, they aren't here Ruby, you've got to branch out, meet people and make new friends," Yang said with a hint of sadness. She didn't want her sister to be friendless or abandon her old friends.

"Yeah and look how that went," Ruby groaned.

"Well, there's that guy with the cast, that's one plus friend!" Yang said, trying to cheer her sister up.

"I'm pretty sure Weiss counts as a negative friend," Ruby said dejected. "Besides, I'm pretty sure dad wouldn't approve of the co-ed situation.

"I know I do," Yang purred as she glanced at the boys in their underwear before Jaune strode past, his headphones on had clothes over his shoulders. Despite his pale skin, he was quite muscular, not buff but more of lean muscle. He was hot!

"Hubba hubba!" Yang whispered as she followed him. He casually tossed his clothes down before calling back and resting with his head on his hand.

Back with Jaune, he was trying to sleep when three shadows came over his and ripped off his headphones. Jaune's eyes shot open and his hand grappled the thief's arm and started to squeeze. The boy cried out and released the music player as Jaune took it back, standing up. He placed it around his neck and glared at the three who disturbed him.

"What do you want!" he demanded.

"You're in our spot, one arm," the tall on said as intimidating as he could. "Move."

"I think I was here first," Jaune replied with a glare. "There are plenty of other spots, some even next to the girls, or do you prefer the company of men? Should 'a known you were a queer."

"Watch it punk!" the tall one spat, getting in Jaune's face looking down. "Unless you want that other arm in a cast too."

Jaune dipped his head and chuckled. "I'd actually like to see you try that!"

The tall one with red hair chuckled and threw a punch, Jaune just ducked under and kicked a leg out. The other tried to punch the hunter in training, but was blocked before Jaune punched him, sending him sprawling. Jaune jumped and spin kicked the blue haired kid who'd tried to take his head phones. He watched the three attackers struggle to their feet.

"I think we need some abidance for this!" Jaune pulled his headphones off and, with a quick jab, flipped them outside in. He licked a button, and the speakers played loudly around the room. (The Time has Come)

The morons all charged at Jaune, who easily dodged and countered their attacks. He grabbed the green haired kids arm before pulling him in and giving him a knee to the stomach. Jaune held on and kicked the kid before pulling him back one last time before letting go and delivering a fierce uppercut, sending the mohawk haired student into the air before sprawling out on the floor. He turned to punch the blue haired fighter away before turning to the red head.

"Come on!" Jaune taunted, "I'm only using one arm here!"

The red head reached for his gear bag before pulling out a large mace, swinging it around before he tried to flatten Jaune. Jaune jumped back and sprinted to his bed and whipped up his coat. In one fluent motion, he put his left arm into the coat before swinging his right threw and then back into the sling. As he spun back around, Jaune reached into his coat and whipped out Blue Rose, posing in a standoff with the mace wielder.

"You got a jacked up notion of fair play pal," Jaune hissed. "And it's beginning to piss me off."

Suddenly everyone froze as purple fragments flew straight at the two, they pinned the red head and his goons to the wall but Juane saw them coming at the last second and rolled away. He looked up to see Goodwitch fuming!

"All of you! Detention once classes start! You are hunters in training! Fighting over a sleeping place! Unbelievable!" Goodwitch lectured before leaving as she release Jaune's attackers. Jaune moved his things to the open spot next to Yang, if anything to prevent the red head and his goons from getting it. He removed his jacket again and fell onto the sleeping mat. He put his headphones back on and changed it to his relaxation/mediation music. He felt as someone's hungry gaze going up and down on him.

"So," Yang began with a purr.

"Let me sleep," Jaune cut her off without opening his eyes. "You can flirt tomorrow, I'm not in the mood." And with that, he fell asleep.

The next morning, everyone was preparing for initiation, after retrieving Red Queen and placing it on his back, he was heading to exit when a flash of red stopped him. He turned and saw Weiss talking with some red haired student. Now Jaune, being a man of modesty and sarcasm, could describe her as nothing but drop dead gorgeous! He noticed Ice Queen, as she had been nicknamed; go into her own little world with lightning and an evil expression. He took that as a cue to smash her back into reality. He casually waltzed up between the two, gave a warm smile and extended his hand.

"Jaune Arc," he introduced himself. "May I have the pleasure of knowing who this lovely lady may be?"

The red head blushed lightly and was about to reply when Weiss hopped in front of him.

"Excuse me, but do you have any idea who you're talking to?" Weiss asked with a superior attitude, arms cross and head in a pout.

"Well, you see Ice Queen. When you meet a new person, you give them your name then ask for theirs, and I am asking for her name." Jaune explained in a teaching voice as if talking to a two year old, going up and down in pitch. "So, since I was asking for her name, you tell me. Do I know who she is? Or do you I need to go over it again?"

"What!?" Weiss cried. "How dare you! I am not a child!"

"Could have fool me," Jaune replied, she huffed.

"This is Pyrrha Nikos, she graduated top of her class at Sanctum!" Weiss explained as if it was a big deal.

"Ok, and I care about this school I've never heard of before why?" Jaune asked sarcastically.

"Uh! She won the Mistral Tournament four times in a row, a new record," Weiss included. Jaune gave her a blank stare.

"The what?" Jaune replied. Weiss had it, she started flailing her arms.

"She's on the cover of every box of Pumpkin Pete's Marshmallow Charms!"

"Do I look like a cereal person to you?" Jaune replied as he starting to get annoyed with her. Before Weiss could rant further, Pyrrha bolted in front of her with way too much enthusiasm.

"Let's try that again," Pyrrha extending her hand. "I'm Pyrrha Nikos." Jaune took her hand and gave it a firm shake.

"Jaune Arc," he said with a smile. "They'll probably be starting the initiations soon." He turned and offered his arm. "May I have he honor of escorting the young champion there?"

"How gentlemanly of you," Pyrrha said with a giggle, taking his arm as they begin to walk off.

"So, you won a tournament four times?" Jaune asked.

"Yes," Pyrrha replied.

"Must have hard as hell,"

"It was, but it was fun all the same,"

They continued to make small talk as they left for initiation, leaving a stunned Weiss behind.
