*3rd POV*

A woman, clutching onto her baby boy, rushes to safety. She's wounded and she want her baby to be safe from the Grimm, but the Ursais and Beowolves were getting closer and closer. She rushes into Beacon, but it was too late, she tripped and fell to the ground, screaming in pain. She clutches her wound and looks back, they were getting closer.

She moves back away from the Grimm as they rushed towards the woman. She closes her eyes and waited for this to end, but... she heard nothing, She looked up and notices all the Grimm were dead, bones were stabbed into the chest. She was confused, but looking at her child, he showed a mark on his left eye, looking like a Beowolf. She laughs and hugged her baby.

"Oh my god," A voice said, "You're hurt!" The woman looked over to see a middle-aged man with tousled gray hair and thin brown eyes. He has a light complexion and sharp facial features. He wears shaded glass spectacles and a dark-green scarf with a small, purple, cross-shaped emblem on it. His outfit mainly consists of an unzipped black suit over a buttoned vest and green undershirt. He also wears black trouser shoes and long, dark-green pants.

"I won't make it in," She said, but she hold out her baby boy, "But... you have to please take care of my son. I want him to see the world, open his eyes a bit better." "Madme," the man said, "I know that we can heal you up and be on your way. Just stay str-"

"I can't," She said, "I already lost too much blood from the Grimm... I can barely even feel my legs anymore. Please... promise me you can take care of my child, strong and smart... balanced. I beg of you!" The man went silent for awhile as he looked at the baby boy, who was sleeping peacefully. "... Alright..." He said, "I promise that he will be in my care." "T-thank you..." She said, "May I know your name before my last breath?"

"Ozpin."

"Ozpin... nice name... my name is... Cereza (L/n)... My son... his name is (Y/n)... (L/n)... thank you....... For taking care of him for... me."

With her last breath, she died. Ozpin gets little (Y/n) and went to get some people who would help Cereza a good burial. Ozpin knows what to do. Make (Y/n) the hunter he wants to be.

*Timeskip to few years*

Cardin Winchester with his mace perched on his shoulder and Jaune Arc opposite him with Crocea Mors drawn, leaning on his weapon as if exhausted, in the spotlight shining on the Beacon Academy auditorium stage.

He looks at Cardin, who laughs at his opponent's tiredness, and Jaune gathers his strength to charge forward and swing his blade at Cardin, only for him to jump out of the way. Jaune looks back, surprised, as Cardin's mace sends Jaune's shield - and himself - flying back. Now only armed with his sword, Jaune continued to try and attack, but is blocked by the mace's hilt. Their weapons locked, Cardin forces himself up, towering over a struggling Jaune.

"This is the part where you lose," Cardin said. "Over my dead-" Jaune is cut short as Cardin knees him in the gut, making Jaune drop his sword and fall to the ground in pain. Cardin raises his mace and is about to slam it down on a worried Jaune just when a long bone come stops  the mace from hitting Jaune. Cardin was shocked to see a teenage boy with (H/c) hair and Light Blue eyes. He wore something similar to Shu Ouma's school outfit over a black trench coat, unzipped. He also wear black glasses, and black fingerless gloves.

"Enough," The teen said, "You did a number." "Why you," Cardin said, swinging the mace towards the teen, but he move to the side and hit Cardin in the stomach, then the face, making Cardin to the floor. "As you see, students," The teen said, "Mr. Arc's Aura dropped to red, which means he's no longer can hold ground and make the match."

While Jaune still lays on the floor in defeat and Pyrrha Nikos looks sad, Glynda turns her head to look at the losing warrior as he pulls out a smaller tablet with his low, blinking stats and that of his entire team. "Mr. Arc," the teen said, getting his attention, "It's been weeks now. Please refer you scroll during combat. It's good to gauging your aura that will help you decide when it's a good time to attack or more a defensive strategy. We can't let anyone like you to be gobbled up by a Beowolf, now, would we?"

"Speak for yourself," Cardin said, before he gets hit with a bone to the head, "OW! What the hell was that for, little brat?!" "That's Professor to you, Mr. Winchester," The teen said, "I may be younger than you, but as professor, I'm strict and don't think your off the hook, considering the grade you have." Cardin grit his teeth in anger. "oh, but be lucky too, Winchester," The teen said, "If I, (Y/n) (L/n), wouldn't stop myself from hurting you, this bone would of been sticking up your ass right now."

That's right. The little (Y/n) (L/n) is a professor to Beacon. Started at age 9, graduated at age 16, the same year Ruby, Weiss, Blake, Yang, and the rest of their friends have been accepted to Beacon. Who knew it would be that quick.

(Y/n) looks to the seated and standing students, such as: Yang Xiao Long, punching the air in anticipation; Weiss Schnee, shaking her fists with an excited smile; and Ruby Rose, shaking her entire body with enthusiastic energy while squealing softly. "Remember, everyone," (Y/n) said, with a blank expression. "the Vytal Festival is only a few months away! It won't be long before students from the other kingdoms start arriving in Vale, so keep practicing! Those who choose to compete in the combat tournament will be representing all of Vale!"

*Bell rings*

*timeskip*

(Y/n) is currently walking to the cafeteria, but he stop himself when he saw Glynda, current Guardian second with Ozpin. "(Y/n)," Glynda said, walking towards him, "I heard that you been teasing with a student. Is that true?" "I wouldn't called it, teasing, but how you or anyone else see it, yes," (Y/n) said, adjusting his glasses, "You see, Mr. Winchester fights with Mr. Arc. Only Winchester wins, but he was about to take one final blow on Mr. Arc, but I stopped it. I hit him with a bone or two. It's been weeks since Mr. Arc have been fully trained and it seems his grades have been poor."

"That's what I want to hear from you, (Y/n)," Glynda said, "Hmm... I want you to look carefully at a couple of teams of your choice. You have the option of watching carefully and seeing if you can help them or not. Will take the offer?"

(Y/n) is silent, but said, "Understood." "Good," Glynda said with a pat on his shoulder, before walking of, "Make me and the teachers proud. And, for once, (Y/n), please act your age for now. We don't want anyone to think you're following the rules." (Y/n) nodded and head to the cafeteria.

Once he got in the cafeteria, he looks around, seeing two group of four having lunch and another group of four teasing a Rabbit Faunus. (Y/n) looks annoed at this and sighs as he leans to wall. He kept examining the two groups. He already known what happened with Jaune. He seen it three times, but if it wasn't for him, he would of been worse. And the attempts of the bullying goes like this.

-Attempt #1- 

Jaune is seen on the way to class as Cardin is going the other way down the hall. When the two pass, Cardin knocks his arm into Jaune and makes him drop his book, then continuing on his way with his hands out as if daring anyone to challenge him. "Ah, come on," Jaune said as a book flies by him, and hits Cardin on the back of his head, "What the?" Jaune looks over to see (Y/n). This is the first time Jaune has seen the teenage Professor. "Um... Thanks," Jaune said in a confusing tone. (Y/n) nodded and walks away.

-Attempt #2-

Jaune and Cardin are about to pass through a doorway, but Cardin clicks on Jaune's sheath and extends it into its shield form as he's going out, causing him to run into his own defense and have it block the exit. "Come on..." Jaune said as he grunts in frustration as he tries to lift his shield back out. The shield has change back to the sheath, and Jaune looks infront to see Cardin up on a wall, few feet from the floor with his boxer on a bone that is pinned to wall. On his forehead, it says "I'm an idiot that tries to hurt others, only to get smacked by Mr. (L/n)." Jaune chuckles at it and moves on.

-Attempt #3-

Glynda and (Y/n) is in the locker room with several students, gesturing at the devices. "Each of you will be assigned one rocket-propelled locker to store your weapons and extra armor. Additionally, your locker can be sent to a custom location based on a six-digit code," she explains to the students.

Hearing this, Cardin looks at Jaune - standing between him and the only open locker in the room - and the cliché plays itself out as Cardin quickly pushes a shocked Jaune into the small dark space and closes the door on him, pressing random buttons on the pad right after that.

"What?! No, wait, wait! You've gotta get me out of here! Please! Don't! Don't! Don't do it!"

It's too late to protest when the locker scrunches down and launches up with a burst of blue fire coming from its base, but before it even soars to the sky, a blue hue glowed, surrounding the locker. It opens and Jaune was out of the locker. Cardin is shocked and notices he was floating and goes into the locker, closed shut.

Jaune watches as the locker slowly soars across the sky. Jaune felt a tap on the shoulder and her looks back to see (Y/n)'s left eye glowing. "You can thank me later... again..." (Y/n) said, walking away. That's the first time Jaune heard (Y/n)'s voice.

-attmepts ended-

(Y/n) sighed in annoyance, thinking of those attempts. He remembered he got bullied, multiple time, but that ended when he showed his semblance. "... Maybe she's right," (Y/n) said to himself, "Maybe I should more of my appropriate moods... But how...?" At that same time the laughing grows louder, mixed with cries from the rabbit girl when one of her ears are tugged on by Cardin. "Ow! That hurts," She said, struggling and grimaces, "Please stop..." "I told you it was real," Cardin said, laughing as he turns to his teammates. "What a freak," Russel said, but stop laughing when he felt a bone hit his head from above, "What the...!" That when CRDL froze and looked up. A glaring (Y/n) with two Phantom-like Dragon heads on each side were looking down at CRDL. "Unless you want to turn to ashes," (Y/n) said, in a angered tone, "I suggest to put your filthy hands away from Ms. Scarlatina's ears, NOW." Scared, Cardin did what he was told and walked off with his group.

(Y/n) landed right beside Velvet and looks at her. "You ok, Velvet," (Y/n) asked. "I'm fine," She said, "But... I don't think my ears are." That's when (Y/n)'s hand touch her rabbit ear and starts to massage, causing Velvet to blush deeply. "P-professor," Velvet stuttered, "W-what are you doing?" "Making sure the pain softens," (Y/n) said, "Does it bother you?"

"N-no. You can keep going."

(Y/n) nods and kept massaging Velvet's ear as she kept blushing from (Y/n)'s touch.

Meanwhile, Team RWBY and JNPR watches this happened. "I keep on forgeting whose's that teen," Weiss said, "And why does he, out of all of our classrooms, not doing his work?" "I guess I know of it," Blake said, getting the two teams to look at her, "What I can get from on Professor Ozpin, his name is (Y/n) (L/n). He lost his mother since he was a baby, whom died from a Grimm ammbushed. Even if his birth mother is dead, doesn't mean he can't be himself, so he kept on being how kids were until at the age of 9, he started studying in Beacon. No team." "Wow," Ruby said, "That's so cool of him."

"Not only that," Yang said, "I heard that he's one of the most unique people to have a semblance like the one he has now... Well... minus the bones and such." They nodded and look back at (Y/n), who just kissed Velvet's rabbit ear. They were shocked that he would do that. "Wow," Jaune said, "He's so... good at what he did."

With (Y/n), when he did the kiss on the ear, he pulls away from her ear and look at Velvet. "Feeling better," (Y/n) asked. Velvet nods and for the first time in like a few years, he smiles. "That's good," He said, "Well, we should be heading to next class. Let's go. I take you there." Velvet blushes again and follows him to the next class.

But, Blake notices something odd. Yang must of noticed and she got her attention. "Blake," Yang said, "What's wrong?"

"I don't know..." Blake said, "But... I could of sworn I saw a little child right beside (Y/n)​​​​​​​."
