I like the idea of soulmate tattoo. (Rwby x Ozpin) no ship shaming.

People are born with a black swirly tattoos on their chest on the left side, right above the heart. At age 16 the tattoo will change color to match your Soul mates Aura. Then the moment you touch your Soulmate after your tattoo has changed color your tattoo will change again revealing your Soul mate's name.

As I am sure you know I do not own RWBY

Waking up the day of her birthday had Ruby more excited than ever. In a little less than 10 hours her MateTattoo would change color. She jumped off the swinging bed to get ready for the day not only was it her birth day but it was the day of the annual Halloween ball that the teachers and the headmaster threw for the students. She went into the bathroom to take a shower hoping she made there before her team, seeing as none of them were in their beds. luckily none of them were there.

She stripped and stepped into the shower forgetting to wait for the hot water to come. She winced at the cold water as it hit her chest, but didn't step out of it. It slowly heated up and she quickly cleaned herself. After the shower she stepped out and stared at herself in the mirror.

She looked at the tattoo that laid right above her left brest. She gave a big smile. She couldn't wait to see the color.

She decided to be a little risque today so she slipped into maching black laced underwear and bra in case she also met her soulmate today. She put her favorite combat skirt on, slipped her shirt on, and laced her corset up. She slid her legs into her stocking and then into her boots. She then put her signature red cloak on.

She then brushed her teeth and hair then left the bathroom. She was stormed by her team as she walked back into the dorm room.

"Ahhhh There's my little sister!" yelled Yang as she placed a hand on Ruby's shoulder.

"finally we were waiting for a millennium!" Weiss retorted.

"30 minutes is hardly a millennium Weiss" Blake replied.

"well anyway happy birthday RUBY!" Yang yelled, throwing up her arms to hug ruby.

"where were you guys when I woke up?" ruby questioned.

"we went to go buy our costumes for the ball tonight" Blake commented.

"without me!?" ruby screeched feeling a bit just.

"don't worry we went to go pick out yours costume because it's your birthday" Wiess said.

"it's not a trashcan again is it?" ruby said in dread.

"No, it's a Dorothy costume" Yang replied happily pulling out the costume from her bag.

"Yang is gonna be the scare crow, because she's a dunce." Blake said.

"No I'm not!!" Yang yelled

"Weiss is going to be the tin man, because she has no heart" Blake continued.

"Hey" Weiss shrieked

"And Blake is the cowardly lion, because she is just a big old Scardy Cat!!" both Yang and Weiss said in sync. Blake just glared at them and took the costume from yang and tossed it to rwby.

"Oh my god guys thanks!!" ruby yelled.

"Well I'm famished, any one care to join me to the cafeteria for breakfast?" Weiss asked while walking out of the dorm room.

"Yeah we'll join you" ruby said for the rest of the team as she followed Weiss.

While walking to places as a team Weiss and Ruby would walk together in the front and Yank And Blake would walk together in the back. Mostly because both Ruby and Weiss knew that if they walked behind or all together it would be awkward for the other two. Both Yank and Blake were Soulmates.

When Yang turned 16 she went to Ruby first to show her once black tattoo had turned to a light purple. The moment it change again she showed Ruby first as well. Her mate tattoo spelt out the name Blake Belladonna in light purple simplistic yet beautiful smooth writing.

Blake had also shown Ruby her Mate Tattoo. It spelt out Yang Xiao Long in bold edgy yellow writing. So after a while they decided to go out and they seem to love each other more and more each day.

They made their way to the cafeteria entering to Nora yelling out about her bazaar dreames again with a huge pile of pancakes on her plate, most likely given to her by her soulmate Lie Ren. Those two aren't together together yet. Taking it slow even though they have been together for basicly their whole life.

Both of them had pink Mate tattoos. Nora's had Lie Ren spelt out in a gentle cursive writing, while Ren's had Nora Valkyrie spelt out in a bubbly writing.

While Nora went on about beawolves, Jaune and Pyrrha just stared at her just questioning this girls imagination. Jaune and Pyrrha were Soul mates as well.

Pyrrha's mate tattoo was out in the open for everyone to see when she wore her combat clothes, but it is hard to notice it seeing as it's white. But it spelt out Jaune Arc in simple but nice writing. Jaune's mate tattoo spelt out Pyrrha Nikos in perfect red writing.

Team RWBY sat down with team JNPR after getting their food. All with a stack of pancakes topped with syrup.

Jaune spoke out " I heard it's your 16th birthday today Ruby, happy birthday."

"yeah Congratulations on another year in this wondrous world" Pyrrha said.

"I hope you have the most epic birthday ever!" Nora shouted.

"Happy Birthday Ruby" Ren simply said.

"Awww thanks you guys, I just can't wait till tonight" Ruby said excitedly.

"Oh yeah around 8 o'clock is when your mate tattoo will change it's color" Weiss said happily. "you have to show me when It has changed"

4 hours later

Team RWBY had finally decided to get ready along with Team JNPR. Jaune, Pyrrha, Ren, and Nora had all agreed to dress up as the 3 musketeers (which in fact had 4 and not 3)

The costumes were not at all what Ruby thothought they were gonna be other than her Dorothy costume the other three were the sexy versions.

Yang's costume consisted of short brown shorts, a green crop top. The scarecrow's hat, some brown patched thigh high stockings and dark brown boots. Some straw would be poping out here and there.

Weiss's costume had her wearing the same type of dress she usually wore but in silver and bold hemming, buttons to act as bolts. Along with a smaller version of the tinmans cap on her head. She had silver stockings as well as silver heels.

Blake's costume was all brown and furry. She wore a brown furry dress that went to mid thigh, and attached to it was a lions tail. She had long brown gloves and long brown stockings on. She chose to wear black heels though.

Ruby's costume was the regular Dorothy costume. Nothing extra, and not too sexy.

They were ready by 4 pm but the ball didn't start until 6. So they all decided to play games. For 2 hours straight they played and watched how Yang utterly crushed them all.

It was 6:20 when they all decided to go. Both team RWBY and JNPR walked to Becon's Ball room. when they got there they had to wait in line for about 16 minutes to get in. Ruby could not stop moving around to anxious to get in side.

When they finally made it in they looked for the best table to claim. Ruby looked around at the decorations. It was very dark. The walls were covered in both black and red paint. from the ceiling hung spiders, bats, and candles. Each table was covered in red paint making it look like blood.

They had three areas. One the dance floor, Two the tables for food and drinks, and Three the lounge area for the ones who like to socialize by talking and not dancing.

The music was loud but awesome. People were already dancing and eating. You would see the occasional chaperone. the most obvious was Professor Goodwitch. Who was dressed up as the Good Witch form wizard of Oz. Then there was Dr. Oobleck dressed as a dog and professor Port dressed as a beawolf.

Yang had dragged Blake off to go dance after they had claimed a table. Weiss and Ruby went to go check out the food and all of team JNPR went off to check out the place.

Around 7:30 Ruby decided to go around saying hi to all the people she knew. She had ran into team CFVY. Coco was dressed up as a witch and Velvet was dressed up as Peter Rabbit. Fox was a Zombie and Yatsuhashi was a mummy.

Ruby had said hi to all the teachers and was about to get back to her friends when she ran into Professor Ozpin. He was dressed up as Ozpinhead from the wizard of Oz. Very fitting.

"Miss Rose, what a pleasure to see you tonight."

"Same here professor"

"what a lovely costume you have on"

"why thank you, and may I say the same thing to you, it quite suits you professor"

"I have heard about your birthday being today, well I hope you have a wondrous birthday"

"why thanks, you know I have been curious about this for a while but if you don't mind me asking who is your Soul mate??"Ruby asked.

"Well miss Rose I have yet to met the person, yes after the many years of living I have yet meet the one person who I'm destined to be with."

"Oh Im sorry, but then may I ask what color your tattoo may be?"

"No harm done, but, well mine is a very common color, just like your father's and your dear mother's my Mate Tattoo is red"

"oh is that so, well I can't wait to see the color of mine."

"well it's always exciting to see it change"

"well yes but also very nerve racking, well nice talk professor but I have to go I have about 5 more minutes until it changes and I promised Yang that I would show her the moment it changed!"

"well yes of course, I hope you have a wonderful evening Miss Rose"

"Same to you Professor Ozpin" Ruby said as she ran off to her friends at the lounge area. Professor Ozpin waved as he walked out of the ball room into the night.

She made it to the lounge area with 3 minutes to spare. She sat of the sofa right next to Yang and right across from Weiss. Blake leaned against the arm rest.

"And now we wait!" Ruby shouted.

"I wonder what color!" Blake commented.

"watch it be some bland ugly color!" Yang joked.

"No it not gonna be ugly, it will be beautiful." Ruby screeched

"well what ever the color may be I'm sure it will be beautiful" Weiss said as every one just stared at her.

"Are you alright there Ice Queen, you're acting nice" Yang said

"HEY!!"

"Ouch!! Hey guys I think it's changing!" Ruby said

They all looked to her as she unbuttoned the top three buttons on her white dress. They stared at her tattoo as it slowly went from black to brown, then slowly faded into a beautiful Emrald Green.

They all stared in awe, well most of them did. Weiss looked a little hurt, but still believed the color was gorgeous.

"My god Ruby it's a lovely color!" Yang yelled.

"I've never seen one so vibrant" Blake said.

"Yes, it's lovely" Weiss said

3 hours laterThey all went back to the dorm all exhausted. Ruby threw herself on Weiss's bed and closed her eyes. Weiss just pushed her off.

"Weiss what you do that for?" Ruby sighed

"Yeah Weiss you've been out of it since Ruby's tattoo changed" Yang said

Weiss looked down and started to cry. "I just hoped that Ruby was my s-soulmate" Weiss cried as she showed her red Tattoo "I just thought, you know."

"Oh Weiss no one would be able to find out who there soulmate is before their tattoo does, it's always seems to surprise us when it changes" Blake said trying to calm her down.

"Yeah, like how was I suppose I would end up with a cat!" Yang shouted all enthusiastically. But got punched in the arm by Blake.

"I'm sorry Weiss, for not being your Soulmate. But I know that you will meet your Soulmate, and they will be way better then me." Ruby said softly.

"It's fine Ruby but I'm pretty sure no one is better than you" Weiss said

"she got that right" both Yang and Blake said in sync.

"Hey I'm not perfect!" Ruby shouted

"Never said you were" Yang retorted

"Ok can we go to BED now!!" Weiss yelled.

"yes Please!" Ruby said as she slipped into pjs and landed back on Weiss's bed. This time she didn't push her off but laid down with her. Blake turned off the lights and the all went to sleep, only to wake up to classes tomorrow.
