[Author's Note: This backstory will be pretty long. Like 3 or more chapters long so, be aware of that.]

On a rainy day, a hooded man is running through an alleyway, holding a baby and a large sword on his back. Once he made it halfway, he places the baby down in the ground as he draws out the sword, preparing to take the child's life to prevent him from becoming Salem's weapon and test subject. As the infant begin to cry, he looks at the sword, wondering if this is the right thing to do, but at this point, he has no other choice. The unknown man raises the sword, ready to bring it down on the infant, but a couple of voices stop him.

Woman: "Honey, did you hear that?"

Man: "Let's check it out."

Upon hearing some footsteps approaching quickly, the sword wielder drops the sword and fled from the scene. A married couple, wearing their jackets and hoods, enters the alleyway only to find a crying baby and a large sword nearby, tilted towards a dumpster. 

Man: "What the hell?"

They spot the crying infant with nobody around. The woman swiftly grab the child, carrying it around her arms. 

Woman: "Hey, it's okay. Sssshhh..."

The baby's crying slowly begins to fade, while the man checks the alley for anyone nearby only to find the sword and investigates it and its peculiar design.

Man: "Huh? What a strange weapon. Who would leave something like this?"

The woman begins checking for any injuries on the infant.

Woman: "Who would leave a baby here?"

Man: "I'm not sure. Maybe his parents just... left him here."

Woman: "That's terrible. Who would do something like that?"

Man: "I don't know. But regardless, we can't just leave this little guy here."

Woman: "You're right. How about we take him home with us?"

Man: "Sure. Christina would love to have a baby brother."

Woman: "Well, what should we name him?"

Her husband ponders for a moment before coming up with a response.

Man: "How about... Y/N?"

His wife nod to him with a warm smile before turning to the infant. 

Woman: "Ok then. For now on, you're Y/N."

The child has now calmed down and begun to sleep. The woman felt relieved, still having a warm smile on her face upon seeing Y/N's sleeping face. The married couple are about to leave, but the husband brings the sword with him, making his wife turn around to look at him.

Woman: "Are you really bringing that thing, honey?"

Man: "Of course. It would be a waste to leave something this unique looking sword near a dumpster. Besides, I could sell this sword for who knows how much."

Woman: "Alright, let's go then."

The woman took Y/N with her while her husband takes the sword with him. After a little bit of traveling, they made it to their hometown, Brightwell, a large town located outside the kingdom of Vale. As the days went by, the husband wasn't able to sell the sword to anyone. Either because they already have a weapon or just not interested in buying it. So, the husband chooses to leave the sword in the basement with the other unused and broken weapons. 


{Brightwell, 10 Years Later...}

Mom: "Y/N! Breakfast is ready!"

In his standard home and trying to get out of his bed, Y/N slowly opens his eyes to see its morning. He puts on his clothes, leaves his bedroom, and makes his way downstairs to the kitchen. Y/N finds his mom cooking and his dad eating his meal. 

Dad: "Morning, sport. You ready to attend Omen Academy?"

Y/N: "Heck yeah!"

His mother places his food on the table. 

Mom: "Well, you better eat all your food before you head out, okay?"

Y/N nodded and quickly sat down across from his father and started to eat. He looked around and noticed that someone was missing. 

Y/N: "Hey, Mom. Dad. Where's Christina?"

His father stare at him, then to his wife, sharing a brief glance before looking back to his son. 

Dad: "Your sister went ahead to school."

Y/N: "Oh... okay."

Y/N feels a little upset about it since his older sister was always there with for as long as he could remember only for her to go on ahead, especially when she told him that she was going to show him what Omen Academy was like. 

Mom: "Oh, don't worry, sweetheart. Christina had to go on ahead. She did go to Omen a year before you. Besides, I heard that you and Christina's cousin, Darius will also be there too."

Y/N: "Really?"

Dad: "Uh-huh. I heard it from my brother that his son will be there. So, go and take this chance to meet him and get along, okay sport?"

Y/N felt happier and thinks that Christina must've gone ahead to meet with their cousin but, also realize they might be seeing cool Huntsmen in action without him. 

Y/N quickly gobble down his food and gives his plate to her mother, grabbing his backpack and getting ready to head out.

Dad: "Y/N, you remember where to go to Omen Academy?"

Y/N glances back at his father.

Y/N: "Yeah Dad. You show me the routes a dozen times."

Dad: "Remember the training I thought you, alright?"

Y/N: "I know."

Mom: "Be careful, Y/N."

Y/N: "I will. Love you guys!"

As he opens the door, the happy Y/N looks at his parents, quickly waving them goodbye as he closes the door. Then, Y/N's mother glanced over at her husband, who was waving back at Y/N.

Mom: "I hope they will be alright..."

Dad: "I'm sure they will."

Mom: "Honey, are you sure sending them to Omen is a good idea? Especially Y/N?"

Her husband gets up from his seat, plate at hand, and putting it in the sink. 

Dad: "I want them to live a good life... we both do. And if having them go to Omen to become huntsmen will achieve that, then so be it. Besides, if they graduate, we won't have to worry about paying for extra protection against the Grimm. Who knows, they might get stronger than their old man?"

Mom: "Oh you."

She playfully punches him in the arm.

Dad: "What? It's true. I'm not the strong Huntsman I used to be, you know."

Mom: "Well, you still are to me."

They began to hug and in the corner of her eye, she looks out the window to see the very prep school her husband attended in the center of town, Omen Academy.


(Later on...)

A girl with light red hair and magenta eyes was looking around the academy for Y/N, after telling Darius to wait for her as she'll get Y/N to introduce him. She was unable to find Y/N inside the academy, so she decided to search outside the school grounds. 

Christina: ("Come on. Where are you, Y/N?")

She then overheard some voices around the corner. Placing her back behind a wall, she peeks over the corner to see where the voices were. Only to find Y/N, injured and on the ground, and three other kids standing in front of him. 

Bully #1: "Hah! I thought this would be a challenge. Turns out I was wrong."

Bully #2: "I know, right? This hasn't unlock his aura or gotten a semblance."

Bully #3: "Idiot! How are you supposed to fight without one?"

Y/N looks at the trio angrily. Despite seeing his expression, they just laugh at him, looking down at him.

Bully #1: "What? Got something to say, weakling?"

Watching all of this, Christina took a deep breath, and rushed to assist by pushing one of the bullies that was the closest to Y/N.

Christina: "Leave him alone!"

One of the bullies fell to the ground, much to the other two bullies' surprise. 

Bully #3: "What the?"

Bully #2: "Hey!"

The first bully got back up and kick Christina towards the same wall Y/N was sitting in front of. Y/N was shocked to see this only for his anger get the better of him. 

Y/N: "You jerks!"

He tries punching the first bully only for the bully to dodge it and the second bully punch Y/N with a fist covered in tiny green flames, sending back on the small wall. 

Bully #1: "What a couple of losers. Don't even know how to fight back."

Bully #3: "Losers~!"

Bully #2: "This is getting boring. Come on, let's get out of here."

The trio of bullies left, leaving the two bruised up. Y/N then wipes off the dirt from his face, glaring after them.

Y/N: "Psh."

Christina slowly gets up from her spot, standing in front of Y/N, who is looking away. Christina takes a deep breath and extends a hand for Y/N. 

Christina: "Let me help you out."

She gives him a smile as she says this. Y/N slowly took her hand as Christina pulled him up to his feet. 

Christina: "Looks like we got beaten up on the first day of school, huh? Well, I'm sure things can only go up from here."

Y/N: "You make it sound like you know this was going to happen?"

Christina: "Well..."

His sister shifts her eyes away from Y/N's gaze.

Y/N: "Christina, wha-"

Christina: "Look, I'll explain it to you once we meet up with Darius."

She then proceeds to grab Y/N's wrist and take him with her to where their cousin is. 

Y/N: "Sis, hold on! I can walk fine on my own, you know."

Christina: "Oh I know. As your big sister, I might as well show you around school along the way."

Y/N was embarrassed by his sister's action but tries to go along with it.


(Little Timeskip)

Darius was sitting by a bench, waiting for Christina as he ate his lunch. Eventually, he spots Christina and another kid she's dragging with her. 

Darius: "Geez, what took you so long, Christina?"

Christina: "Hehe, sorry. Just showing my little brother around the school."

Darius: "Oh, you must be Y/N, right?"

Y/N: "Y-Yeah. You must be Darius?"

Darius: "Uh-huh."

As they finished introducing themselves, Y/N then looks at his sister, and she notices his gaze.

Y/N: "Alright, Sis. You going to tell me why we got beaten up in school grounds."

Darius: "Wait. You didn't tell him, Christina."

Christina closes her eyes, takes a deep breath, then looks back at Y/N. 

Christina: "Alright, Y/N. You remember what Mom and Dad tells us about Omen Academy?"

Y/N: "Well, yeah. It's a secret fifth academy in Remnant. It's governed by teachers and staff, who are strong Huntsmen and Huntresses like the other academies, right?"

Christina: "You're right about that, but there was more that I found out about this academy."

She then explains that Omen has no connections with the other four academies, just like how Brightwell refuses to have no connection with the other four kingdoms. As for the staff, not only do they govern the school, but also the rest of Brightwell. They and the locals probably wanted to start their own kingdom with their own academy, and with their own rules and regulations for everyone here to follow. In this school, students with powerful semblance are more favored by the staff and gain a higher chance to graduate.

Darius: "No way..."

Y/N: "That's so stupid! Why didn't you tell about this before, Sis?!"

Christina: "Well, you were so determined to attend Omen to be a huntsman, beside I was planning to tell you but, second years must show up to school early. 

Y/N: "Wait, is that why you always come home with bandages and bruises on your face and arms?"

Christina: "Y-Yeah."

She looks away from Y/N as Y/N walks up to her and grabs her shoulders. Christina then looks at Y/N with a serious look on his face.

Y/N: "Sis, you should have told me or Mom or Dad! I was worried that something bad happened to you!"

Christina looked dejected for making her little brother worried about her.

Christina: "S-Sorry..."

Darius: "Hey, Christina, shouldn't we tell a teacher about what just happened to you two?"

Christina: "No, I don't think so. Unless we all have powerful semblances, the teachers and staff here wouldn't do anything about it."

Y/N clenches his fists after hearing her response.

Y/N: "That's unfair." 

Christina: "A-Anyway, why don't we eat some lunch since we're here? Oh Darius, you almost done with your sandwich."

Darius: "Yeah, I guess."

Christina: "Come on, Y/N, let's eat before classes start."

As they eat their lunch, the three of them start chatting with one another, getting to know each other. Just like Christina, Darius has a weak semblance. Despite that, they were all weak and that's what they had in common.

Christina: "Hey guys, how about we form our own team?"

Both Y/N and Darius raise their brows at this. 

Darius: "Is that even allowed?"

Y/N: "Does the school allowed teams?"

Chrstina: "Well no but, if we're together, then we don't have to stand or fight alone! With my Energy Manipulation, Darius's Shockwave, and Y/N's semblance, we can make it through this school year and beyond!"

Y/N just sighs at this.

Y/N: "Sis, I don't have a semblance, remember? I don't have an aura either."

Christina looks at him, giving him a warm smile.

Christina: "Don't worry, Y/N. Sooner or later, I know you'll unlock them. Right, Darius?"

Dairus nodded in agreement and patted Y/N on the shoulder. Once more, Y/N just sighs.

Y/N: "Whatever you say, Sis. I'm in."

Darius: "Me too. So, what's our team's name going to be?"

Christina thinks for a moment, until an idea pops into her head.

Christina: "Oh! How about the Terrible Trio?"

Darius raises a brow at this while, Y/N just looked confused at her response. 

Y/N: "Why that name?"

Christina: "Well, we're kind of the weakest bunch and to be honest, I'm kind of terrible in using my semblance. What about you, Darius?"

Darius: "Y-Yeah, same."

Y/N: "Huh?! But they sound so cool!"

Darius: "Yeah, but I can only use it briefly. Christina is the same as well."

Christina: "Weeelll... what do you guys think?"

She waited patiently for their responses until one of them did.

Darius: "I guess, I'm fine with the name."

Christina: "Y/N?"

Her eyes sparkle, waiting in anticipation for his response as Y/N thinks for a moment.

Y/N: "Alright. We're... the Terrible Trio."

Cheerfully, Christina begins to wrap her arms around the two boys, much to their surprise.

Christina: "Ok then! As the Terrible Trio, we'll train, fight, and do all kinds of stuff to become huntsmen together!"

Darius: "We can even explore all of Remnant too?"

Christina: "Heck yeah!"

She raises her fist in the air as she said this. Darius does the same. Y/N reluctantly does it too much for his embarrassment.

As the weeks went by, the three kids supported each other, and they had a lot of fun together. Even though Y/N and Christina could fight, Darius was the strongest out of the three of them. So, whenever they ran into trouble with bullies, he always did his best to protect them. It didn't always work out for them but, they got used to these run-ins eventually. Aside from the occasional beat-downs, they were content with the way things are in Omen Academy. Well, one of them wasn't. Whenever he comes to Omen, he's often looks frustrated and angry every time. Any run-in with any bully they had, all he could do is watch, visibly angry as he does nothing. 


(Later on...)

At a small park, after some training, the Terrible Trio are resting on the ground. Christina looks at Y/N's expression, looking upset. Concern over her little brother, she asks. 

Christina: "Hey, something on your mind?"

Not a moment later, he responds. 

Y/N: "Don't you guys think it's unfair?"

Darius: "What is?"

Y/N: "The school, its system, everything! Why do we have to suffer and get beaten every day while other kids can do whatever they want just because they're a bit stronger? It's so stupid."

Darius and Christina share a look with one another. They then look back on Y/N, who's remains upset and resumes speaking.

Y/N: "I want to become a badass Huntsman. I didn't sign up to get beaten up every time I go to school."

Christina: "Hey, cheer up. That's just how things are."

Darius: "Besides, there's nothing we can do about it, anyway."

Christina: "The best we can do is endure until, we become strong, graduate, and become huntsmen."

Y/N: "Psh... whatever..."

Y/N then walks away while kicking a pebble away as his sister and cousin stare after him with some concerns in their expressions. Y/N had a lot of issues coming to terms with the reality of his situation. Even though Christina and Darius had very weak semblances, at least they have one, while Y/N got nothing to defend himself. Fighting through punches and kicks means nothing when a kid just activates a semblance and wins easily. They always try to cheer him up, saying he'll eventually unlock his semblance and it'll take some time.


(The Next Morning...)

Y/N was reading a book, minding his own business until his sister suddenly barge into his bedroom. 

Christina: "Hey, Y/N!"

Y/N: "Hey, ever heard of knocking, Sis!?"

Christina: "Oh, sorry. But Y/N, last night, I had a dream!"

Y/N raises a brow at this. 

Y/N: "A dream? About what?"

Christina: "Yeah! It was about you, me, and Darius! We were using our semblances and we were fighting a lot of Grimm!"

Y/N's eyes lighten up once heard about him using a semblance.

Y/N: "Wait, what?! Really?!"

Christina: "Yeah! There was a sort of beam or ray coming out of the palm of your hand!" 

Once he heard that, Y/N remembers one of the bullies they dealt with, having a ray coming out of their hands too and the fact it was just some dream made him frown.

Y/N: "No way, Sis..."

Christina: "Huh?"

Y/N: "Don't joke around like that. It's not funny."

Christina: "I-I was trying to cheer you up."

Y/N: "If you're way of cheering me up is making jokes about me not having a semblance, then yeah, that's really hilarious."

Christina goes quiet for a moment before responding.

Christina: "S-Sorry."

Y/N also went silent for a moment as well.

Y/N: "I... I know..."

Christina was about to leave before looking back at her little brother. 

Christina: "I'm going to Darius's house so we can train and practice. You want to come with me?"

Y/N was looking away from his sister's gaze before grabbing a book and sit on his bed.

Y/N: "N-No thanks... I'll... I'll just get in the way."

Christina: "Ok... bye..."

Y/N: "Yeah..."

Christina closes the door, feeling upset that she unintentionally made fun of Y/N's lack of a semblance. Looking back, it did sound stupid to Y/N. For as long as he could remember, every kid in Brightwell was able to unlock their semblance before attending Omen. Some were much stronger than others. Yet, he's the only one who hasn't even unlocked his. While everyone practices their semblances and fighting styles, Y/N would often sneak away from home, trying to get his semblance to unlock. Punching the air, extending his arms and concentrating, and many other things. Deep down, Y/N really wised her sister's dream would become reality. He couldn't stand being weak and powerless. He always wanted to be stronger so that he could win, just like how the Huntsmen would always win in the end of the storybooks he read before by his parents. Like a hero who always saves the day in the end. 


(A Couple of Days Later...)

Y/N's mother was preparing for dinner, while Y/N continued reading his book on a nearby table. 

Mom: "Y/N. Can you go and grab a frying pan down at the basement? It's a sliver-colored one."

Y/N: "Sure, Mom."

Usually, his dad would help his mom with cooking but, his father hasn't shown up due to his work around Brightwell, and Christina is busy with her studies. Y/N casually heads down to basement. He looks around for a sliver pan only to find old furniture, old clothes, and multiple boxes, either closed or opened. The boxes that were open had various weapons poking out on the top. Y/N is amazed at the weapons he's seeing. Then again, his father was known to put away weapons he wasn't able to sell. Out of all the weapons he was looking at, a large sword among the other weapons caught his attention. 

Y/N: "What a weird-looking sword. How did Dad even get this thing?"

Y/N checked the exit to see no one else was entering the basement. Y/N approaches the sword and the moment he goes to grab the sword's handle and pulls it out of the box, his head begins to feel fuzzy and begins to see images in his mind. As his eyes closed, Y/N saw a Grimm Dragon, looking straight at him.

As well as many types of Grimm he had read in books and some he's never seen before, all appearing and looking at him. Struck by fear and dread, Y/N continues breathing heavily and unable to move. Looming over him and the various Grimm was a pair of giant crimson red eyes, staring him down. 

Y/N: "...!"

He tries to yell and scream for help, for his mom, dad, Christina, for anyone. But nothing came out of his mouth. Before he knew it, the visions he was seeing quickly faded away, the sword pushed him back, flinging him away a few feet, his aura now unlocked only to be flare up upon impact. The sword fell and hit the floor. His mom calls him out through the slightly open door.

Mom: "Is something wrong, sweetheart?"

Y/N slowly opens his eyes as he gets up to his feet, shaking his head, recovering from what just happened.

Y/N: "I'm fine, Mom. I just... fell."

As he said this, he looked at the sword on the floor for a moment before finding the silver pan, he was looking for. Y/N grabs the pan and begins to exit the basement, all while still looking and checking out the sword, which is still on the floor. The weird feeling, he had when he held the sword fades away as Y/N sighs before closing the basement door.


(Next Day...)

In school grounds, the Terrible Trio had a run-in with the same trio of bullies that beat up Y/N on his first day. Darius and Christina were crouching, wincing at their injuries, while Y/N got pushed to the wall.

Christina: "Please, Y/N, stay down! You can't beat them!" 

Y/N slowly tries to get back up, standing on his feet, looking angrily at the trio of bullies in front of him.

Bully #1: "Lookie here, guys. Weakling Y/N is still trying to act tough. Even though, he's the weakest chump there is."

Darius: "L-Leave h-him alone."

Bully #2: "Why? We're just training our semblances and aura."

Bully #3: "Yeah! Who knows? We might become better huntsmen than you guys!"

Outraged by their comments, Y/N lunges towards them, ready to punch one of them only for the first bully kicks him in the stomach, sending him back to the wall again. 

Bully #1: "Man, it must suck not having a semblance, huh? Too bad you can't be a huntsman without having a useful semblance like mine."

The first bully smiles as he extends his hand in front of Y/N's face. A small energy begins to form in the palm of his hand. 

Bully #1: "Here, let me show you what a semblance is really like."

Christina: "Y/N, run away!"

Darius tries to go and help Y/N, but he's still exhausted from his fight with the bullies and his injuries don't help. Y/N wants to hit this guy, dodge, move, anything, but he couldn't due to the injuries he received. He was afraid. Afraid that this attack might severely hurt him, afraid that his and cousin will also be hurt by this. Afraid that his powerlessness might be his way of life for now on. 

Bully #2: "Hey, weakling! You watching closely!?

Y/N gaze at the beam the bully is charging up, almost mesmerized by it.

Y/N: "...!"

As Y/N blinks his eyes, his (F/C) eyes turn crimson red. Before he knew it, Y/N raised his arm just like the bully did. The bully and his friends were shocked to see this, along with the tiny red and black energy ray forming out of Y/N's palm. Darius and Christina were watching this, just as shocked as the bullies.

Christina: "...!?"

Darius: "Hey, are you seeing what I'm seeing?!"

She didn't reply to Darius's question as she was focusing on Y/N's sudden change in eye color as she could have sworn, she saw them glowing a bit. 

Bully #1: "What the?"

The lead bully managed to dodge Y/N's tiny but slow energy ray. He angrily stares at Y/N, who has no idea what's going on now.

Y/N: "W-What?"

A punch lands squarely on Y/N's face, sending him falling to the ground, and his aura flaring around him. 

Bully #1: "Damn brat! What the hell was that!? You really think you can fight back!?"

Bully #3: "Y-Yeah! I-Idiot! Know your place!"

One of the bullies placed a hand on the first bully's shoulder. 

Bully #2: "Hey, don't get so worked up. He's just a weakling, he's not worth the effort."

Going silent for a moment, the lead bully, still frustrated, glances over to Y/N, who is still sitting on the ground. 

Bully #1: "Come on, let's go. Better to just leave them to feel sorry for themselves." 

As the trio of bullies left, Y/N is left there in silence, until the silence is broken by his sister's voice."

Christina: "Y/N! Are you okay?"

Y/N: "Of course not. We just got beaten up, again."

Christina: "Yeah, but you just use your semblance just now!"

Darius: "Didn't you feel it just now?"

After calming down a bit, Y/N slowly gets up.

Y/N: "Well, I felt... something in my hand but-"

Christina: "Your eyes! They turn red too. Darius and I both saw it."

Y/N: "My eyes?"

Christina: "This is what we've been telling you, Y/N! You were going to unlock your power eventually. And now, you did it!" 

Y/N: "H-Huh?"

Y/N gaze upon his hands for a moment, not sure what to say for a bit."

Y/N: "So, it was real... I really did use a semblance just now!"

He looks towards his sister and cousin, who nod at him. Y/N grins happily.

Y/N: "YES! I do have a semblance! I'm not powerless after all! I can be a huntsman! I can be a hero!"

Jumping in excitement, Christina and Darius were happy for him. It was the happiest they had ever seen Y/N. Christina moved in to hug Y/N, while Darius joined in. Y/N was hugging them both all while all of them were happily grinning at one another. Once they come back home, Y/N and Christina rush home to tell their parents about Y/N unlocking his semblance. Once they told them about it, they were filled with so much excitement in their voices. Y/N's parents were so proud of him that he was able to do it. They even celebrate this by giving Y/N's favorite meal for dinner. Never knowing how much this would his life... their lives from now on.
