Jaune and all the seven kids were in the Ozpin office as the knight sat in front of the headmaster with Ruby sleeping peacefully in his arms while the rest of the kids, slowly dozing off on the ground beside him, tried to stay awake. It was night-time when they arrived and the person who owns the place looked at them with a dumbfounded face, like he was trying to intimate a fish.

It took more time than he thought before going to the headmaster's office.

A few hours before

Jaune holds both Ruby and Nora's hand while the rest of the kids grab each other by hand on his side. Team RWBY on his left while his teammates on his right.

He needs to bring all the kids back to his dorm to wash all of them from the pink powder on their hair and clothes. He doesn't know if it's safe or dangerous, but he wants to make sure to clean all of it before they could breathed it in anymore.

As he tried to guess as to what they were while walking back to his team's dorm, a sudden idea came crashing into his mind which cause his heart to drop as he halted in place, the pink dust he found this morning. He petted the pocket which supposedly held the dust in panic and found it was empty. A pit suddenly forms in his stomach under this realisation…

He stares at the ground with an unblinking wide gaze as fear and guilt slowly swarm his thoughts. Heartbeats increase, drowning out any noise. His hands tightened until his aura flickered a bit and teeth started to grind with one another.

"Dad…" He heard quietly. "Are you okay?…"

Bringing his eyes right in front of him, he saw Ruby, continuously tugging at his right top side with worried looks and tears in her eyes. Staring at her just for a moment before focusing on the kids behind her who had the same worried expression with the young reaper. It causes the voice on his head to slowly calm down, he didn't even notice that he had held his breath as he tries his best to stabilise his breathing with eyes closed.

Seconds past, the kid's eyes were met with a smiling Arc with a gentle stare as he opened his mouth. "Yeah… dad is just fine…"

"Are you sure dad?" Yang spoke as she took a step closer.

"Yup, your dad just remembered that he had to go to a doctor tomorrow to take his injection." He lied quite easily.

All their faces, except Weiss, become pale when they heard the word 'doctor'.

"D-don't be scared dad… w-we will be there for you." This caused a small smile to appear on Jaune's face as he let out a chuckle at what Ruby had said.

"I appreciate the gesture." He hugged all of the kids in a tight hold, which the kids, but Weiss who was stunned at the gesture, enjoyed and wrapped their tiny arms on him as well. Revelling in the hug, Jaune opens his eyes slightly to show a bit of coldness and distant gazes.

Jaune Arc… you need to take a hold of yourself.

At this point, there wasn't any time for any freak out or blame himself for what had already happened. What he should focus on right now was to fix his mistakes. Whatever punishment the future has for him can wait or after he has washed them. And he should go now, he could hear a couple of student's voices from behind him.

"Okay everyone, are you all ready to take a shower and go into the bubble bath adventure?" He broke off from the hug and greeted the reaction with a wide smile.

Most cheered at this while Blake hissed with her cat ears flat to her head, which he raised an eyebrow.

So, he took all of them to his dorm's bathroom quietly and boy cleaning them was a hassle, Yang was like a cat, punching or kicking him every time he touched her hair to put on some shampoo. Same with Blake, who was a cat Faunus so that kinda makes sense, although it was about her getting into the water. Thank Oum he has aura to negate the damage, even though they were small kids, their hits actually hurt him. Nora was also one of the kids that he needed to fight while cleaning them. At least she didn't try to hit him, just running around and almost eating the soap. Ruby was the same, but it was pretty tame to handle because she didn't try to eat the soap, simply running around with a big smile.

While the rest of the kids, they were much easier to handle. Pyrrha and Ren didn't move too much or did anything, he still needed to watch them from the soap getting into their eyes or they slip down though. As for Weiss, she's the easiest from all of the kids. She didn't move at all and waited for him to clean her, listening diligently to every order he gave. Kids may not be that dumb and hardheaded, but he sees a lot of them to know that they were really curious and energetic. So, it was kind of unnerving to see a kid that was really obedient, like a robot. But he brushes it off, thinking it was normal for an Heiress to do so.

Oh, he had just learned from Pyrrha that she was a famous singer. So he researched about her, thinking he can sing a song to woo her, and found out she was a daughter of the SDC or whatever. He never used dust so he doesn't know what the business was when he was a kid, not like he cared about any of it now as an adult.

When he cleans them while take a bath, it reminds him of the old days, when he usually took a bath with all of his sisters, it was a nice memory to reminisce about.

After he was done cleaning and drying them. He had to find clothes that at least cover them because they didn't have any clothes or underwear that fit them, so he chose his spare hoodie, it's comfy and cover them nicely, also, they like it. They begin to walk with him holding their hand as they create a chain of hand holding beside him and meet Ozpin at his office, all the students have already went asleep at the time he finished cleaning them, thank Oum for that. Now, all that was left was to meet the headmaster and solve the problem.

Back To Present

Said person seem like has finally rebooted from the bomb shell he had dropped.

"So… you are telling me that when your group did the dust project where you accidentally blew up yourself to outside of the class. After you made your way back, you found the rest of your friends have de-age by the look of it to be 12 years and you think it's because of the pink dust you found in your pocket this morning. Am I right Mr. Arc?" Ozpin asked as he recap the whole story from Jaune POV, pinching the bridge of his nose as the headache seeped into his mind.

Jaune nodded slowly as he didn't want to awaken the small girl in his arm.

"So how do I reverse all of this." Jaune asked quietly in a hopeful tone.

Ozpin leaned back to his chair and look up to the ceiling, like he was deep in thought. Silence filled the room and anxiety filled his mind once again, the only thing could be heard was the gears in the clock tower turning and all the kids sleeping peacefully while his body still tense.

"I don't know." Ozpin finally spoken.

"Excuse me sir?" Jaune didn't know for sure if he hears that correctly or his heart tried to deny of such a possibility could even be possible.

"Throughout all my life, I have never seen this happening before." Ozpin gestured to his friends beside him who were sleeping. "Never have I seen dust that could turn a person into kid or de-age someone."

"so… are you telling me that we can't do anything?" Jaune asked worriedly.

"Yes Mr. Arc, I'm afraid even I don't know how is this possible or fix any of this." Ozpin shook his head. "The only thing we can do is either wait for the effect worn off or let the expert of dust to research it and try to reverse it or…" The headmaster turned his head toward the window, away from the boy. "Just accept the situation as it's."

"Are you saying that we just left them stuck as a kid?" He asked, feeling absurd at the idea itself.

"We don't have any choice." Ozpin face him as he shakes his head gently "I am deeply sorry about this." eyes show sympathy at the blond kid.

Jaune sagged in depress to the chair, there wasn't a way to fix all this, his friends may or may not be stuck as a kid forever and it's all his fault.

Ruby's eyes twitch at the sudden movement and begin to shift around in discomfort, letting out a small soft whimper. Noticing this, he sat straight again and rocking her back and forward slowly as well humming in a calm melody until he can feel the tension leave her body and her breathing become steady once more, he sighed in relief with a fatherly smile. He then hears a chuckle in front of him.

"Seem like the kids have imprinted you as their dad." Ozpin commented with a small smile.

"Wowowow..." Jaune whispers, not wanting accidentally to wake up the girl or any of his friends once again. "I can't become their dad, I am too young."

"Why not? You seem very good at handling children." Ozpin pointed out.

"Uh-ah..." Jaune stammered. "Can you just send them back to their family?" Jaune sighed, it wasn't because he dislikes them, it's the opposite. However, he was still 18-year-old teenager and huntsman-in-training. He does not have the money to support them and himself at the same time and the time for them with him having school and homework, all that stuff. So let them to go back to their family would be the best option he has.

"We can't do that." Ozpin shook his head.

"Why?" Jaune raised an eyebrow.

"Beside keeping this a secret from the public so it won't create a problem-" Before Ozpin can continue, Jaune cut him off.

"I am sorry to cut you off sir, but why the news of my friends accidentally got turn into a kid could cause an issue?"

The headmaster suddenly gains a serious expression before explaining it "If the news there is dust that can de-age someone, essentially make them have eternal youth or just live longer, what do you think will happen?" Jaune eyes widen in realisation and horror.

"People will want to put their hand on it and fight over it. It will cause a havoc throughout Remnant." He said in horror.

"You are right Mr. Arc, it may or may not cause a huge issues if this news get out to the public. And with the dust that did it might be the last of its kind, it will cause a lot of conflicts. And there's a chance that people will be targeting team RWBY as well as your team to be experimented on to extract a fragment of the dust that had entered into their body." Ozpin informed him.

Jaune was speechless and Ozpin gave him time to absorb the information and the threat that can happen. He didn't realise that one dust can cause this much of trouble. If only he didn't bring the dust to the class and only bring it to a professor when he was done. Once again, his heart became heavy as he brings his eyes down at the floor.

"What was the other reason?" Jaune asked quietly, still not looking at the man.

Ozpin gazes at the blond with sympathy, much preferring for his teammates to tell it when they want it, but without any choice, he must be the one to inform him. "Lie Ren and Nora Valkyrie are orphans." He announced with sympathetic eyes.

Jaune's head shot up at the headmaster, eyes wide open as the only thing coming out from his mouth was "what?" Before it suddenly became dried.

"That is right... Mr. Lie and Ms. Valkyrie lose their hometown and family to the assault of the Grimm when they were still a child, everyone beside them perish in the event." Ozpin grabbed his table and opened the document that contained the history of the village as he read through it, to remind himself of another failure of his, eyes slowly becoming dull when he gazes at the amount of casualties. "They are from the village Kuroyuri in the continent of Anima on which the kingdom of Mistral is located. I have tried to sent Huntsman and Huntress to eliminate the Grimms there, to save at least the remaining survivors. However, the amount as well as the species roaming there were enormous and extremely dangerous. Even after a decade, we are still 65% of reclaiming the area and we haven't killed the dangerous Grimms. The fact that two kids survived after experiencing such tragedy and escape was a miracle on their part." He further explained to him.

With each information given to him, the grip of his become tighter and tighter until his aura flickers to prevent his nail to dig through his skin.

He never knew this, he meant he had asked them where they come from or their family, he really did want to know better about them. However, they seem uncomfortable and sad when he asks for it, in case of Ren, he becomes even more distant than usual. So, he didn't try to pry it and wait for them to be ready to tell everyone. Now he knows why they look uncomfortable about it and give a subtle pain look unconsciously.

"But… Can I really take care of any of them when I have my own problem to deal with? I don't even think I have the lien for the stuff they need." He said in a sorrowful tone, hanging his head low.

Without wasting any seconds, Ozpin reached out to his jacket and pull something, putting it on the table so Jaune can see what it was.

"A credit card?" He looked at the man in front of him with confusion clear in his eyes.

"It's my credit card, you can use it to buy all the necessary things you need, and I will give you a week of free time so you can prepare yourself, this is all I could do for you." Ozpin explained with a smile before giving a stern look. "And I'm sorry to say this, but you still need to keep up with your studies and training while keeping an eye on them. I, however, will try to make arrangements with the staff for the children to have their own private room while you are in a class so you can have an easier time to watch over them once the week is over. And if it's possible, you could leave the kids with one of our staffs if they are free"

Jaune still feels nervous and anxious at the thought of becoming a dad and taking care of children, well, technically his friends but it's the same thing. What if he made a mistake or something bad happen to them. It only fuels his anxiety even further.

"Can you at least help me to take care them too?" He desperately asked.

"Sorry but I still am a headmaster, so I won't have time or the authority to help you any further than I have." Ozpin sipped his coffee before giving him a smile that somehow annoyed him.

Jaune sighed before nodding back, knowing that he can't convince the headmaster to change his mind. So, his only option was to follow along.

Jaune shake the kids beside him and in his arms. "Come on kids, it is time to go back and have a nighty night." They begin rubbing their eyes and yawning cutely, while Ozpin was still giving him that annoying smile, like he found something to entertain his life for a while.

Jaune start to smirk as a mischievous idea enters his mind. "Come on kids, say goodbye to Grandpa Ozzie." He put down Ruby on the floor.

Ozpin's jaw hangs open, dumbfounded by the action. Before he can do or say anything, all the kids hug him with a smile and chorus cutely. "Goodbye grandpa Ozzie." The old wizard suddenly become frozen like stone, unmoving for a few seconds.

An old, locked memory resurfaces without any warning. A memory of 4 beautiful daughters, calling him dad and asking to play with them. And a lovely wife who give him an affectionate smile, cupping his cheek and leaning forward as he does the same.

"Sir..." Jaune called out softly, snapping him out from the memory. "Are you alright?" He looked with concern while the kids look in confusion.

Ozpin shook his head. "Yeah, yeah I'm fine... what wrong Mr. Arc?"

"It's just sir... you are crying." Jaune gestured to his face.

Ozpin put a hand to his cheek to notice some tears has indeed been running on his face, like Jaune said, he had been crying a bit.

"It's just some old and painful memories, that's all." He answered calmly as he wiped the tear away, though his eyes still show sadness and regret. Like someone that wishes to turn back time and fix something.

"I'm sorry..." Jaune apologises with his head hanging in shame and guilt.

Ozpin bring his hand up to stop him. "You don't need to be sorry, it's not your fault." He reassured him, "I believe it is time for you to go and take a rest." He points to the time.

Jaune was silence for a few seconds before nodding. "Yeah. I think you are right" He pick up Ruby again and walk toward the elevator with the kids follow him like little ducklings following their parents.

"Goodbye little ones. Don't give your father too much trouble now." He said warmly with a soft and a tender smile as they began to leave.

"We will grandpa!" Nora said happily as she was holding Jaune free hand. Ozpin chuckles to himself as he watches his 'grandchildren' walk into the elevator before the door closes. The room filled with dead silence as the sound of the gears turning can be heard.

"Grandpa Ozzie..." He speak out loud as he tried it on his tongue, a smile began to show on his face. "It has a nice ring to it." He said to himself as he gazed out from the window, wondering what the future would hold for the blond knight who had just become a dad with 7 kids... and... his 7 grandchildren.

"This will be the most interesting year in the whole history of Beacon." He said with a fond smile, his eyes filled with joyfulness and happiness, happiness that had been lost for many, many centuries since something he held dear had been taken away from him.

With Jaune

When they arrived at his sister dorm, he stares at team RWBY bed, the bed that was hanging by a rope while the other one was getting hold up by books. His sight lingers at it for ten seconds without blinking, then slowly shut the door and turn around to team JNPR dorm.

He may have already seen it a few times before and didn't think about it too much, because they have Aura to protect themselves. However, they were now kids and don't have access to aura on top of it all. It will be too dangerous with how energetic they were in the case of Nora, Yang, Ruby jumping on it.

"What's wrong dad?" Weiss asked, tilting her head like a puppy.

"Don't worry about it." Jaune replied with a smile. "All of you are going to sleep in here." He walked to his dorm and open it.

The room was much simpler than his sister's team and the bed was still on the ground luckily. He didn't bring much from home, only some of his comics, clothes, etc. While for the rest of his teammates, he could only tell that they only bring clothes and other stuff. For Ren, he has some herb and cooking utilisation while Nora didn't have anything out of ordinary which was quite surprising, or she simply hides all of her crazy bomb experiment, pancake, and other bizarre stuff somewhere in the school, when you are dealing with the queen of the castle, expect the unexpected. As for Pyrrha, it was the same case with Nora, not the theories he has for the bubbly girl.

That mean they had few free spaces compared to the sister's team that they haven't use up until now.

"But dad, where are you going to sleep?" Weiss asked as she gazes at the four beds.

"I already have a place to sleep, so everything is fine." Jaune lied as she petted her head, much to her confusion. "Come on kids, let tugs you all to sleep before the bug bed gets you."

"Not the bug bed." Ruby and Nora exclaim in fear as they hurriedly run to one of the beds.

He chuckled at how innocent they were as he leads all of them to their own beds, helping the kids to get on the bed by pick the children up and tucking them in one by one. He let out a satisfied breath once it's done, proud of his own work.

"Welp, good night everyone." Jaune waved at them as he tried to make his way out of the room, before he could leave Ruby called out for him.

"Where the good nights kiss dad?" She asked, tilting her head cutely.

"Ah-uh-eh..." Jaune was flustered and embarrassed, he can already guess why they want that because they were just kids at this moment. However, they were still his friends that got turned into one. Giving them the good night kiss on the head was still embarrassing.

The five of them give him puppy eyes with Ruby and Nora being the most effective one, making him swallow his embarrassment and walk toward them. He gives a quick kiss on their forehead before walking away. They giggled as he does it. Everyone, except Weiss who look extremely confused at the affection and Ren who was smiling ear to ear.

"Good night dad." All of them said in unison.

"Good night." He waved again with a smile with cheeks still red.

Once the door closed, he began to plan out everything that needed to be done before the end of the week.

He should go out to vale to do a shopping spree tomorrow. Clothes, underwear, soap for kids, books, and possibly toys were necessary. Another thing that's an absolute necessity were ingredients to cook. He doesn't want to insult the chefs in Beacon or over-hyping his skill, but their cooking was really bad compared to his own cooking. He had learned and trained to the utmost back at home thank to his sisters and mom and boy. Some of his sisters were really picky eaters too, so he has to learn a lot of different styles of cooking and food to satisfy them.

Anyway, the food in the cafeteria was average and kinda unhealthy. He never tell anyone about it, because he knows he will somehow end up becoming the cooker for his team and possibly the sister team too like Ren if they found out that he can cook, and he didn't really want that.

I'm sorry Ren, for leaving all the cook at you but I don't want to become a chef for, at least, if we included Nora, 15 people again like at home

He guesses it's time for him to use those skills again and probably the rest of the teaching that his sisters and mother have hammered into his brain when he took care of his younger relatives.

At least he doesn't need to be concerned about the money thanks to Ozpin as he brings the cards into the air and gazes at it with stars in his eyes before shoving it back to his pocket. For the rest, he can figure it out along the way.

Before he ends the day, he slowly opens the door again , so it won't disturb the kids as he leaned his head in and stared inside the room. Yang and Ruby snuggle to each other in Nora's bed, same with Nora and Ren in his bed. Blake curled up like a cat with Weiss, who was sleeping quite still, beside her in Ren bed, finally Pyrrha slept in her own bed. They sleep peacefully and without any worries.

He smiled at how calm and peaceful they were before closing back the door, his soul filled with more resolve to take care of them with everything he got and protect them from any harm, forgetting that he still has nowhere to sleep…

…

….

…..

He slowly lost that smile of his as he leaned his back against the wall and slid down until he was on the ground before covering his face with both hands. After a moment, a single lingering thought, always haunting in his head since he realises the reason they become like that, comes out of his mouth.

"It's all my fault…"

Today has been a long day and he doubt it will get any better soon.
