Ozpin has seen a lot of things but seeing a human what was once Ruby Rose's weapon was a new one. Though she has been a human for a few hours, she seems to have a good grip on how to act. Crescent stood next to Ruby as they both reported to Opzin.
"So this Living Weapon still out there?" Ozpin asked.
"I was more focused on getting Ruby out of there. He wanted me to kill her and was going to do it himself." Crescent said.
"One of the living weapons injected me with something that cause my aura to just...err...shut down, I think," Ruby added.
"He had already turned a lot of weapons into people and had them kill their owners. I was able to destroy his way of doing so, but I don't think it will keep him from his plans." Crescent said, keeping the book a secret.
"And what is his plan?" Goodwitch asked.
"Wish I knew for sure. He just trying to give weapons their own human life but at the cause of killing humans." Crescent said.
"It's going to be hard to explain this to the school," Goodwitch said.
"Even so, Miss Rose?" Ozpin said.
"Yes?" Both Ruby and Crescent answered.
"Ruby Rose." Ozpin corrected.
"Yes?" Ruby answered.
"I'll leave it to you to take care of your Living Weapon until we can find a way to change her back," Ozpin said.
"Yes, sir!" Ruby said, understanding.
"Crescent Rose?" Ozpin said, turning to the human weapon.
"Yes?" She answered.
"I want you to stay with Ruby like you always do when she takes you out on her missions and tests. Learn what you can about human life." He told her.
"Yes, sir." She said, nodding.
"We'll come up with a plausible story later. For now, just say you're Ruby's older cousin that came for a visit." He told her.
"Um, sure?" Crescent Rose said, confused.
With that, both Roses were dismissed. Ruby turned to her human weapon, remembering one thing that she did.
"Thanks, Crescent Rose." She said, making the other Rose turn to her.
"It's no problem. I wasn't going to let you die." She said, pulling Ruby into a one-arm hug.
"I'm still surprised how fast you act like a real human," Ruby said.
"As am I. I think when I was turned human, I was given everything that a human has. Like I was living like a human all my life." Crescent said, thinking.
"Well, I think it's cool to find speak to you as a human. I hope the other time wasn't embarrassing when I spoke to you as a weapon." Ruby said, blushing a bit.
"It wasn't. I might not have been alive but I did recall all the things you said. Strange, now that I think about it." Crescent said.
"So, what are we going to tell my friends?" Ruby asked.
"I say the truth, then we tell them that I'm your cousin," Crescent told her.
Team RWBY Dorm,
"So, until Opzin can find a way to change her back, she's our cousin?" Yang asked once they heard the story.
"Yeah, I think Professor Ozpin was to keep this on the low. And I'm still trying to get over what I saw." Ruby said.
"Are you sure she should be your cousin?" Blake asked.
"What do you mean, Blake?" Yang asked.
"Well, Ruby made Crescent Rose. Shouldn't they be...you know...mother and daughter?" Blake asked, blushing.
"Mother and daughter? OH! I'm an aunt!" Yang smirks, catching on to what Blake was saying.
"M-M-MOTHER?!" Ruby shouted, blushing.
"Um, Blake? You do know that Ruby is two years young than most students here, right?" Weiss asked, sighing.
"I'm just saying that they are a lot closer than cousins," Blake said, looking away.
"Yum! I never ate any food before, but I can tell they taste delicious!"
Team RWBY turned to see that Crescent Rose was eating some cookies, which surprised Ruby as those were her secret stash cookies!
"Where did you get those?!" Ruby asked, shocked.
"Oh, you told me. Remember, you were tired of Yang trying to hide away all the cookies and hid some in your "Secret Place", so you can snack on them whenever you want." Crescent Rose said, handing one to Ruby.
"Aw! I was wondering why I was finding cookie crumbs around the bed." Yang said, causing Ruby to sigh as she took the cookie.
However, Crescent spotted the book peeking out of her pocket space, and quickly push it back in before anyone could see it. She didn't want anyone to know until she had a look over it.
Later that night,
Crescent Rose open her eye to see Ruby was fast asleep. She was wearing spare PJ clothes that Ruby had, though they were a bit small. However, she climbs down carefully before grabbing her clothes. She enters the bathroom and changed her clothes. She then opens the window and slips out. It took her a while, but she was able to find Weiss's, Blake's, and Yang's weapons and was reading the book.
"Hmm, so for weapons to become human, they need some dust and...magic?" She said, reading the book.
Can she even use magic? But she had to try. She needs to understand the transformation a little better. She wasn't going to let Sallan kill any more humans and she couldn't do it alone.
"Crescent Rose?"
She almost jumped when she turns to see Ruby walking up to her.
"R-R-Ruby?! What are you going up this late?" She asked, shocked.
"I had to use the bathroom and I saw that clothes on the floor and the window was open," Ruby said, causing Crescent to facepalm.
"I forget to cover my tracks." She whispers.
"And what are you doing with my team weapons?" Ruby asked, noticing them.
"Sallan isn't going to stop. He already has an army and he could attack humans. I know the world has its problems with the Grimm, but I can't let him get away with it. But I can't do it alone. Fight dust fire with dust fire as they say." Crescent Rose said, causing Ruby to sit next to her.
"So, what's with the book?" Ruby asked, pointing.
"It's what was used to turn me into a human. I'm trying to figure it out. It said here I need dust and some kind of magic." Crescent said.
"Magic?" Ruby asked, confused.
"I don't know. But I notice the spell here. It said, "Given life to lifeless beings. Reborn in a new life. Given life to become something new." She read.
Suddenly, both Ruby and Crescent started to glow, causing the weapons to do the same. A bright light covers the area, causing many students, as well as the teachers, to awaken from it. The light faded as Ruby and Crescent held on to each other.
"What just happen?" Ruby asked.
"I don't know," Crescent said before noticing four girls laying on the ground.
The first was a young girl, around 12 years old. She had snow-white hair with a silver crown on top of her head. She was wearing a light blue with red and blue jewels. The other girl looked like a cat faunus with black hair, around the age of Crescent Rose. She had black clothes that made her look like some kind of maid. The last two looked alike. They wear around the same age as the first girl. Both had red hair and yellow clothes.
"Um, did they just?" Ruby asked before each girl groaned.
"Ugh! Weiss, can you turn off the light?" The young girl asked before sitting up.
"Myrtenaster?" Ruby asked, confused.
"What time is it?" Said the black girl.
"Gambol Shroud?" Ruby asked, shocked.
"Ah, we wanted to sleep in," The twin girls said.
"Ember Celica?" Ruby asked, lost.
"Hm, Miss Ruby? What are you doing out here? Wait, I'm a Faunus?" Gambol asked.
"Huh?! WOW! We're human!" Ember and Celica shouted.
"How did that happen?" Myrtenaster asked, surprised.
"Yes, how did this happen?"
Everyone turns and saw Professor Goodwitch standing close by tapping her foot.
"Um, it's a bit hard to explain," Ruby said, sheepishly.
And here's another. So, Crescent Rose told Ozpin and Goodwitch about what happened but kept the book to herself. Though they were to going under the cover story that Ruby and Crescent are cousins but it looks like Crescent Rose wanted to prepare for anything. Now I know it might seem far too soon for Crescent Rose to bring the other girls in but I wasn't fully sure how to do it. As for the looks, you can just check Tikoriko on DeviantArt for Crescent Rose's and Myrtenaster's looks, but Gambol Shroud and Ember Celica were a bit trickier due to Tikoriko fusing the two together in his comic. So, I went with a maid look for Gambol Shroud and twins for Ember and Celica. Though just to let anyone know, the maid idea is based on Blake's life back in her home, and she's also one of the fighting kind of maids. Feel free to think of Gambol, Ember, and Celica as you wish.
