How strong is Jin Rose/Branwen?

Right now Jin is helping Ruby with some of her homework from miss Goodwitch and it was one of her hardest subjects in her opinion is hard.. Dust. Jin has study and learn stranger things, but for Ruby round Dust a mysterious energy source that could that's everywhere in Remnant or in all of the four kingdoms. Dust is really is heard to understand as it can be use in many ways and not much we can learn from this power, but in the future maybe in do time they can see what potential lies in Dust. So in other matter in hand Ruby is looking at many of the Dust that Weiss lend her with Jin she can probably ace this.

Ruby: "Thank you bro! I really need an "A" for this homework."

Jin: "It's fine besides you always need my help in the end." Jin said as he sets up some Dust crystals.

Ruby has Dust vials that contain different Dusts as for Jin to bring different types of crystals of Dust. How did Jin get this? it's from his days being a hard worker and earning Lien from jobs and from his parents that made him do hard chores. Jin bought some crystals from Vale after he woke up as for helping Ruby with her homework. After a few moments later Jin and Ruby set up the crystals and vials in both sides also Jin has the answer sheet as he passes every class knowing he's the smartest in the family. But, this is do to the many times he been doing tech back in his worlds as it was more hard to understand.

Jin: "Okay Ruby you must understand that I won't tell you the answers so you got to work."

Ruby(does the puppy eyes): "Pretty-"

Jin: "That's not going to work on me sis and you better work like I do. So! *pulls up a clipboard that has the answers* Can you identify between the use of Dust crystals and the Dust vials? and can you tell me what they can be use for in battle and for every day lives?"

Ruby(puffing her checks/mad): "You're unfair! and a baka!"

Jin: "The only thing I hear right now is "Thank you big Bro!" and no answers." Jin said with a smirk.

Moments later Ruby is holding a mix Dust vial that contain a mix of fire and wind and she trying to figure out what it could it do for the Kingdom. But, this answer is opinion question so Ruby has her free write to what it can be use for minus a weapon! because Jin bet as this answer would be not irrelevant to that of Goodwitch criterion.

Ruby(frustrated): "PLEASE BRO!! CAN I JUST WRITE IT CAN BE A WEAPON AND I CAN EXPLAIN IT IN FINE DETAIL!!??" Ruby pleaded to Jin who gave a sigh.

Jin: "Ruby I said my answer so many times as before and I'll say it again. If you want to impress miss Goodwitch you got to be creative with that question if you do she would think of you as a future huntress."

Ruby(mad little girl): "BUT IT SO HARD!!!!" She said as she shakes the vial.

As the vial shakes some dust came out like pollen and Jin sees this and knows one thing... Ruby is going to sneeze!

JIn(drops the clipboard): "RUBY DON'T SHAKE IT!!!" Jin says as he runs over to Ruby.

Ruby: "Huh? *sniffs the dust* uh.. Uh.. UH! CHOO!!!"

It was too late and Ruby sneeze and dust powder went all over the place and I do mean it went everywhere that in the end there was an explosion at the end. Once the explosion happen you can bet your ass all two teams and a certain blond it coming. Also to add to this Summer, Tai, and Qrow are coming to the school as well plus Raven as she's now a mother to Ji. So in a matter of minutes later after the smoke clears up y Ruby waving her hand to blow away the dust.

Ruby: "*cough, cough!* Jin! *cough* bro are you alright? *cough, cough*"

There's silents until she hears some kinds of rustling as something or someone is struggling to get rid of some clothes on them.

Ruby: "Jin? where-"

Ruby cut herself off as she sees some of Jin clothes that are lying on the floor and some kind of small lump. The lump starts to move as it looks like something or again someone is trying to get out. Ruby then slowly move towards the clothes that Jin was wearing a removes some of it and to her eyes beam with shock and surprise what she found..

Ruby: "Jin... is that you?" She said in a shocked tone.

As Ruby looks down to see a boy whose around five to six years old clearly naked as none of the clothes fit him. From the clothes that are covering him up he has a unique hair style that only one person has in her life. Also having tiny tattoo on his left side of his arm and to above and beyond this kid is no other then Jin Rose/Branwen/Kazama.

Kid Jin: "*looks at Ruby with a confused face as he tilts his head cutely*

Ruby: "I need to tell the guys before mom and everyone comes!"

(Time Skip to Ruby struggling to explain to kid Jin who he is and just take him to her team and not to make him cry)

Third POV

In the dorm room of team RWBY as the three girls do their things like another normal day. Weiss is sharping her nails, Blake reading her "books"(if you know what I mean), and finally Yang whose doing push ups and about to plays some games on her scroll, but what sticks out is their leader Ruby Rose whose doing homework with her brother.

Weiss: "They're really taking their time studying."

Yang: "Well its Ruby, Weiss and what do you expect from them?"

Weiss: "...True, but do-"

Before Weiss could say anything forward everyone heard knocks on the room and they were from their door.

Weiss: "Wow looks like my wish came true for their return."

Yang: "I'll get it!" Yang said as she gets up.

Once Yang open the door and about to greet the both of them she notice that Jin was not with her, but rather weird. Ruby came by herself and hiding something before Yang could say anything Ruby cut her off.

Ruby: "I'll explain, but let me in first and don't freak out." Ruby said as she holds the hidden item or person.

Yang:"Okay..."Yang said as she moves herself for Ruby can come in.

As Ruby came in Weiss and Blake notice that she's acting strange as she came in as she looks at Yang as she closes the door. Once Yang close the door Ruby was holding, but more like carrying something like... a kid of some kind.

Weiss: "Ruby Rose what are-"

Ruby: "Okay! before I can explain anything I want everyone to give your full attention right now its very important."

Yang gets close, Weiss starts to come close as she stops what she was doing, and finally Blake stops reading and jumps down from her bed to give Ruby her attention as well. Once done she starts explaining, but to their surprise she didn't go crazy on explaining.

Ruby: "So when Jin and I started as Jin starts helping me with some stuff as he bought some Dust crystals with his money. Once done I was in the last one and.."

Weiss: "Ruby what did you do to my Dust?" Weiss said in angry tone.

Ruby: "I kinda... sneeze and.... Jin and I kinda... exploded.."Ruby said in a worry and timid tone.

Weiss was about to burst in with so much rage, but gets cut by Ruby.

Ruby: "But! there's anther thing that happen after that... well after the explosion that happen and when everything is clearing up... well..." Ruby kinda started to get nervous and the thing or person started to move.

Blake: "Ruby what are you hiding? also is that your dog again?" Blake said in a nervous and scared tone ready to jump away from him.

Ruby: "No, no! he's with team JNPR, but never mind that right now and to answer that question well its what happen in the result of my actions."

Ruby then reveals what she was hiding and once she what was hiding everyone were in deep shock.

Weiss: "Is.."

Blake: "That.."

Yang: "Jin!?"

The three girls look at what Ruby was hiding to see a young and kid size Jin who looks confused and scared.

Ruby: "Yup.... this happen after the explosion... HEY! at least we have a baby brother now! right?" She said as she has a nervous smile.

The three looks at Jin and could only think of one thing as they knew about what happen with their mothers towards Jin.

Weiss/Blake/Yang(mind): "The world is going to end when the two moms sees this." They all said in unison in mid thought.

Kin Jin: "Onee-chan..."He said in a timid tone as he puts his face towards Ruby chest area.

Ruby didn't see the problem as this was her fault that her big brother is like this and what he's doing is quite normal.

Yang: "AWW~ I think that word that Jin said means older sister or big sis! that's so cute!"

Ruby: "Yang! *she looks down at Jin* um... Jin I'm going to teach some things like English and... and *idea* COOKIES!"

Kid: "Cowkie? Engwish? huh?" Jin said as he's more confused then before.

Blake and Weiss turn around and cover their mouths as they found that cute from Jin even tho he's a kid. But, a few second later Weiss came towards him.

Weiss: "Don't worry I won't hurt you.. it's okay." Weiss said in calm tone.

As Jin is covering himself, but as Weiss spoke to him he looks over to her and sense that she wasn't evil.

Kid Jin: "Konnichiwa.." Jin said towards Weiss.

Ruby POV

Before anything could happen Weiss fell for his cuteness and pulls him away from me and hugs him.

Weiss: "OH MY OUM!!! YOUR SO CUTE!!!~" She says as I see Jin trying his best to push her off of him.

Blake: "So to be straight to the point here Ruby. Once you and Jin started to work together you sneeze into a vial of Dust and I only can assume that you were shaking it. Once that happen the explosion went off and once the dust was cleared you've turn your adopted older brother Jin between five or six years old child." She said in a bluntly tone.

Ruby: ".....Yeah..." I said in a sad tone.

Yang: "Okay, look! right now we need some clothes for him! he practically naked at this point!" She said as she points at to the over size that are covering Jin as he pushing Weiss face away.

Ruby: "You do have a point.... but where do we get the clothes?"

Blake: "We could ask team CVFY, but I think that would lead more problems."

Yang: "We could always make them."

Ruby: "THAT'S A GREAT IDEA!"

Blake: "Well we should do right now before Jin starts to get angry." She said as she points at the where Jin is.

Yang and I turn our heads to see Jin in his... I would say half devil thing as he has tiny wings and trying his best to fly away from Weiss. Weiss is running around chasing Jin as he's now flying around in circles.

Weiss: "Come on! just a little more! please!"She said as she chase Jin as he is flying away from her.

Kid Jin: "Tasukete! kono kemukujara no shiroi kami no shojo ga watashi o oikakete iru!"

Yang: "PFFF! HHAHAHAHAHAHAHA!"

Blake: "*face-palm* Oh Oum..."

Ruby: "Okay! we have no time to waste then! we need some help so lets ask team JNPR as they know about his whole power thing. Also control Nora before she crushes Jin when she sees him."

Blake/Yang: "Alright!"

Later

Moments later we all calm down Jin and brought team JNPR also some items for clothes for Jin. Once team JNPR saw Jin current state Ren, Jaune, and Yang pulled back Nora before she went full on hug that could killed him. It took about ten minutes for calming down Nora and after moments later Pyrrha and Nora started to talk or play with Jin as he started to move away from them, but failed when he got interested what they were talking to each other. Mostly you can tell that Pyrrha and Nora were tricking Jin as they talked about some stuff that caught his interest and curiosity because he's now a kid. Around with Jaune, Ren, Weiss, and me we were making some clothes for Jin as he need clothes for his tiny body of his now. Lastly Yang and Blake are cleaning the stuff that Jin and I left when we were at when the whole thing happen before anyone else gets suspicious about the mess we made.

Nora: "OH~ aren't you so cute!~" She said as she poking Jin cheek.

Kid Jin: "Go way!" He said as he waves his hands at her hands, but failed to fight back.

Pyrrha: "He is Nora! look at his hair and! *lifting him up* look how light and well balance he is!" She said as she rose him up.

Kid Jin(red): "Yameru!"

Ruby: "I never knew making clothes can be so much... fun?" I said as I never knew this could be fun.

Weiss: "You should learn it from me Ruby because I know how to sew." She said as she was making some pants.

Ren: "I already made pants for him I think he likes it." Ren said as he smiles as he made Jin small black pants.

Jaune: "True! when he saw the pants that Ruby and Weiss made for him he ran to you." He said as he made me a bit angry.

Weiss and I made some clothes I made some red and yellow pants as Wiess made some baby blue and white pants and Jin ran towards Ren. He shock his head fast and Ren showed his including underwear that are red and he took it. The reasons behind the underwear thing is that we thought that it would better if the guys did that. But, now I regret it as he now likes more to the guys then me... ME!? his sister!? this means war.

Yang: "Hey Ruby I just realized something."

Ruby: "What?"

Yang: "Our parents are coming to check up on us." She said as she starts to sweat.

Ruby: ".....Oh...." I started to sweat as well and turned pale.

Jaune: "Come on guys! what-"

Before Jaune can finish his comment we all heard knocks on the door and Yang and I started to panic.

Ruby: "Yang! *picks up Jin from Pyrrha* catch!" I said as I toss Jin to her.

As Jin was tossed he had a dead-pan expression as he was tossed towards Yang and she caught him.

(Author: Can I get a YEET! and a F for my boy Jin as he just got yeeted through the air)

Yang: "I got it! *catches Jin as he lands right onto her breasts surprisingly and place him forward to her face to face* I got you bro! also how did you feel about the landing?" She said with a smug look.

Kid Jin: "Baka." He said with a dead-pan expression.

Ruby: Go to the bathroom and be with him! hide him from our mom!"

Summer(the other side of the door): "Ruby! Yang! we're here!"

Weiss: "Go! Yang!"

Yang: "Alright! hold your horses! *goes to the bathroom and starts to talk to Jin" So bro what do you want to know?"Mama to papa wa doko ni iru no ka shiritai

Kid Jin: "Mama to papa wa doko ni iru no ka shiritai?" He said as he was getting carried by Yang into the bathroom to hide.

Once Yang and Jin went into the bathroom to hide as everyone in the room starts to clean up and after a few moments later they clean everything. I clean myself off and open the door to see my mom, dad, Uncle Qrow, and my now recent Aunt Raven we were all waiting outside behind the door.

Raven "Finally!"

Summer: "What took you so long honey?"

Ruby: "Oh! uh we were um... cleaning up! and we wanted to make sure that we have our room safe! plus I brought my friends to help as well! but come in!"

All four of my family members came in and started to look around and see that one person is missing.

Raven: "Ruby where's my-"

Summer: "Your brother?" She said correcting aunt Raven.

Ruby: "Um! he had to do..... something! he went in his way to do something!" I said as I lie to them.

.....Yeah I'm not a really good liar am I.

Tai: "Angle that's a horrible lie so tell us the truth. Where's your brother?"

I was going to say something until everyone heard noises in the bathroom. I panic as my friends as well.

Qrow: "What was that noise kid?"

Ruby: "Um no-"

Yang(muffled): "JIN CALM DOWN!! STOP!! I KNOW YOU- IF YOU-"

I knew one thing after another that... I'm going to be in deep trouble Aunt Raven was about to marched towards the door until. The door burst open and and Jin flew out and once he landed he started to slide and spinning as he slid towards my family. Once the slows down and stops as Jin looks up towards his family everyone looked at him with shock and said in unison.

Summer/Tai/Qrow/Raven: "SON!!/KID!!"

Kid JIn: "?"

(Time skip as Summer and Raven declare war once again as Kid Jin is in the middle of this whole chaos and everyone else is looking from afar as they are seeing the great war)

Third POV

Ozpin: "Okay to get this straight Jin was helping you with your work.(mind) Why the fuck does this always happens to Jin?"

Ruby: "Yup!"

Ozpin: "You made a mistake as you shook the vial of Dust and sneezed and created a exploded and with that exploded. Your adopted brother Jin turned into a five year old child."

Ruby: "Uh huh."

Ozpin: "Due to that you try to create clothes for Jin as he's now a kid so after that when your family knock on the door. Yang took Jin to hid it from them to the bathroom and as everything is happening outside of the Jin was trying to get away from Yang as he wants to know what's happening."

Yang: "Yeah."

Ozpin: "As Ms.Xiao Long chased Jin as he was trying to get away from her the both of you made a huge mess. That soap and many other things was created and once you caught him Yang slipped on some soap and once that. Jin went flying through the door and slid down the floor. But, before he through the door Ruby told a lie, but didn't work against her family and then Jin slid down and once everyone saw this it was chaos."

Yang: "Pretty much."

Ruby: "Yeah..."

Weiss: "I knew that we all knew that we had to clean up the whole mess!" Weiss said in a angry tone.

Blake: "True!"

Ozpin: "Once Summer and Raven saw... well... I should say more, but.."

Everyone turns towards the two also Jin sitting on a chair nibbling on a cookie that Ruby gave him. As the two most strongest people in Beacon are fighting also wrestling who gets Jin... again and the stakes are high as Jin is now a kid. Both Summer and Raven are wrestling each other to hand to hand.

Raven: "I'M TAKING CARE OF HIM!! NOT YOU, YOU FATTY MAKING WOMEN!!"

Summer: "NO! I'M TAKING CARE OF HIM!! YOU YOU MILK TITTY CHICKEN!!"

Raven: "AT LEAST I HAVE A FIGURE THEN MAKING THEIR CHILDREN FAT!"

Summer: "OH!!?? LOOK HERE! AT LEAST I DON'T OVER FEED THEM! BUT, AT LEAST I'M NOT A WOMEN WHO ABANDONS THEIR CHILD!!"

Raven: "FUCK YOU!"

Summer: "NO, FUCK YOU!"

Raven: "OH HELL NO! FUCK YOU!"

Summer: "OH NO YOU DON'T!! FUCK YOU!"

Raven: "NOT ME! LET ME HELP YOU!! FUCK YOU!"

Summer: ""

Raven: ""
