A/N: This is my first fanfiction so I'm bad at these Author Notes. So why did I make this fanfiction, you may be asking? Well, I thought of an OC (orignal character) and his name is Yin Xiao Long. There is one on the internet already but I thought, "Hey, if you're going to make a twin of Yang Xiao Long, why not name him Yin?" More about the OC will be written in this author note.

I also wanted my OC to have a relationship with Blake since she seems like a good character in RWBY. So I just told you, there will be some moments between them. Also, please do not use this to link the story in RWBY. This is not CANON (part of the OFFICIAL story) and I just wrote this fanfiction for fun.

RWBY belongs to Rooster Teeth. So, Rooster Teeth, please don't sue me. :)
An ability of my character is based off of Assassin's Creed Eagle Vision. So Ubisoft, please don't sue me as well. :)

My OC:

Name: Yin Xiao Long (twin of Yang Xiao Long)

Age: 17 (just a few hours older than Yang)

Appearance: Exactly like Volume 5 Yang (including long hair,) but with a coat that has two coattails in replacement of her regular coat, and a pointed hood is also included

Weapon: Nanobot Bracers (like Iron Man's nanobot suit in Infinity War) - can transform into any weapons but Yin prefers a flail sword and plasma blaster

Semblance: Eagle Sense - like Assassin's Creed, Yin can detect people and objectives behind walls, but his regular senses are boosted twenty times above the average person's regular senses; Yin uses it when he investigates something

Extra Abilities: lightning speed (no, I'm not kidding) and detective skills (from his Semblance)

Personality: swinging mood (happy one second, can be angry the next), usually has a calm and cool personality

Hobbies: training, reading, sitting on the roof with peace and quiet

POV: Yin Xiao Long

"Oh, my sister and brother are going to Beacon with me!" Yang exclaimed happily. "This is the best day ever!" She had every reason to be excited. Yang, Yin and Ruby was going to Beacon Academy, home to the most powerful and successful Huntsman in the world of Remnant.

"Please, stop..." Ruby begged, being choked.

"Just let her go, Yang," Yin playfully told her, giving her a light punch to the shoulder. She instantly let go and was jumping about, her body telling her that she was ready to be transported to Beacon at any time. He knew that she was who she was, an outgoing girl that would lose her temper quite easily. And he was fine with it, no problem at all.

Suddenly, a blond woman appeared from a hologram projector nearby. She began to speak in a serious manner.

"Hello, and welcome to Beacon!"

"Who's that?" Yang asked.

"My name is Glynda Goodwitch!" Yin had talked with Ruby and Yang about what happened in a shop when an orange-haired man decided to rob the store.

"Aaand, there's your answer," Yin deadpanned.

"You are among a privileged few who have received the honor of being selected to attend this prestigious academy. Our world is experiencing an incredible time of peace, and as your future duty as Hunstmen and Huntresses, it is your duty to uphold it. You have demonstrated the courage needed for such a task, and now it is our turn to provide you with the knowledge and the training to protect our world." The hologram instantly disappeared after the message.

"Oh, wow!" cried Ruby. "Look, you can see Signal from up here! I guess home isn't too far after all!"

"Beacon's our home, now," Yang stated to her. They then heard a passenger groaning and bending over nearby, dashing towards the back of the ship.

"The view isn't for everyone, I guess," Yin pointed out.

"Nice moment while it lasted," Ruby said. Her face lit up immediately after. "I wonder who we're gonna meet! I just hope they're better than Vomit Boy. Oh, Yang, gross! You have puke on your shoe! You too, Yin!"

"I'll go get the fire hose," sighed Yin.

"Gross, gross, gross, gross, gross, gross, gross, gross!" Yang yelled.

"Get-Get away!" Ruby yelled along with her. "Get away from me! Get away from me! Get away from me! Get away from me! Get away from me!"

A/N: And this is my fanfiction. Hope you enjoyed it and I'd like to hear what ideas you have for me to write!

P.S. Sorry this was a short start to the story. I had to cut a few uninteresting bits from the official canon in order to make this better.
