Hello everyone before you read this story, I need to tell you something. This story was on my old account on a different website, and I don't use it because of reasons. Well I hope you enjoy. Steven Universe and Ninjago do not belong to me.
It's another day in a small village workshop on a hill, there two sister's named Ruby and Lapis who live in the workshop. Ruby the oldest sister, a gem, and short( even though she's older) while her youngest sister Lapis is a human, and is taller then her older sister.
Ruby: *making a sword* To make the perfect sword you first need the right metal and plenty of heat. Cool it off...and WHAT THE! *her sword got tangled up*
Lapis: *laughs* You made it too quickly, Ruby. Be patient. If mother was still here, she'd say...
Ruby: I know...no matter how much fire you have experience isn't something you learn overnight. That may work for you, Lapis, but I'm gonna be a better blacksmith than mom ever was.
Sensei Nanefua: *entering the shop* Hmm...your metal is loud and heavy. Useful to slow one down. Useless in the art of stealth. All tools for a samurai, but nothing for a ninja?
Ruby: ninja? Huh, you're a long way from finding a ninja in these parts, old lady, and the shop is called "Four Weapons," not "For Browsing". Either buy something or get lost.
Sensei Nanefua: Hmm...too bad. Thought I'd find something special here.
Ruby: Fine let me sh-...*Nanefua disappears*...she was just... ah who cares.
A dark cloud then appears over the village, heralding the arrival of the Skulkin. Upon the arrival, three Skulkin Generals appear riding a Skull Truck
Nuckal: Oh, oh. Let me go first! Please, oh please? I'm dying to go down there.
Kruncha: You nitwit, you're already dead! Try to control yourself in front of Master Samukai. With all due respect master Samukai, last time...you did say...I could go first.
Samukai: Sorry boys, this one is mine. Just remember what we're after and find that map. ATTACK! *all the Skulkin Vehicles accelerate in full speed*
The citizens of the village charge at the oncoming trucks
Samukai: Boo!
The citizens turn and flee as the Skeleton Army rushes past them.
Lapis: *noticing them from the shop* What are they?
Ruby: I don't know. Stay here *grabbed her gauntlet and runs off*
Ruby battles the Skulkin warriors as one of them decapitates themselves and bites Ruby's foot
Ruby: Ow! Bite this! *kicks the Skulkin's head away*
As two skeletons clap for the extraordinary performance, Lapis sneaks up with a sword behind them and performs a stealth attack
Ruby: I thought I told you to stay back!
Lapis: And what? Let you have all the fun gem sis?
As the siblings fight the Skeleton Army, Kruncha and Nuckal sneak inside the shop unnoticed and start looking at the merchandise inside
Kruncha: You're not looking hard enough! *hits Nuckal with a samurai helmet*
Nuckal: Ow! You're not looking hard enough! *hits Kruncha in retaliation*
As the two Skulkin Generals continue tussling each other, they come across the map Samukai was looking for
Kruncha and Nuckal: The map!
Back outside, Ruby finishes the last of the Skulkin warriors when Samukai approaches her. Ruby held out her gauntlet out while Samukai takes out four daggers
Ruby: This is bad.
Samukai easily disarms Ruby and knocks her down without a problem. As Samukai was about to finish her, but a golden tornado approaches Samukai and attacks him
Sensei Nanefua: *inside the tornado* Ninja Go! *attacks Samukai*
Samukai: Sensei Nanefua! Your Spinjitzu looks rusty.
Sensei Nanefua: Nothing like bone to sharpen its edge, Samukai.
Samukai notices ruby knocked down and a water tank above her. Samukai then throw his daggers at the support legs to timber the tank towards Ruby.
Ruby: *noticing the tank* Oh no!
Sensei Nanefua: Ninja Go! *performs Spinjitzu and rescues Ruby*
Samukai: *retreats into his Skull truck with the map* Mistress Quartz says take the girl!
Nanafua: Mistress Quartz?
Ruby: Take who now?
Kruncha laughs as he launches the truck's bone hand to grab Lapis
Lapis: Help me Ruby!
Ruby: Lapis!
The Skeleton Army escape with Lapis in their hands
Ruby: They took Lapis...I'LL DISTROY THOSE-
Sensei Nanefua: I told you.*hits Ruby's head with a bamboo stick* Useless.
Ruby: Argh! You could've done something! You could've used your...ballerina dance or your...
Sensei Nanefua: Spinjitzu!
Ruby: whatever, But you did nothing! I'm going to get my sister back!
Sensei Nanefua: Where they go, a mortal cannot. That was Samukai, king of the Underworld. And if it's true that he's carrying orders for Mistress Quartz, then I fear things are much worse than I ever thought.
Ruby: Mistress Quartz?! Underworld?! What the heck do we have that's so important to them and why would they take my sister?! WHAT THE HECK DO THEY WHAT FROM HER!?
Sensei Nanafua: What's so important? How about everything in Beach City itself? Long before time had a name, Beach City was created by the First Crystal Gems, by using the Four Weapons of Spinjitzu! The Whip of Quakes, The Sai's (Author's note: this will be her weapon for now until it's revealed in Steven Universe) of Lightning, the Spear of Ice and the Gauntlet of Fire! The weapons are so powerful, that no one can handle all of their power at once! When she passed away, her step daughter and daughter swore to protect them, but the oldest was consumed by darkness and wanted to possess them. A battle between sisters broke out and the oldest was struck down and banished to the Underworld. Peace returned and the step sister hid the weapons, but knowing her older sister's relentless ambition for power, she placed a guardian to protect them. And for fear of her own demise, a map for an honest woman to hide. That honest woman was your mother. The older sister is Mistress Quartz and I need to find those weapons before she does.
Ruby: You're the step sister? Then you came here looking for the map?
Sensei Nanafua: No. I came for something greater. You. Since my sister cannot enter this realm, it's obvious she has struck a deal with Samukai. If she were to collect all four weapons, even I would not be able to stop her again. But you, you have the fire inside. I will train you to harness it. Use it. To become a Crystal Gem.
Ruby: Look, I'm flattered to think I'm all that, but I going to save my sister! I'm not getting involved in your sibling rivalry. So screw this conversation, I'm going to find my sister.
Sensei Nanafua: *knocks Ruby down as she tries to walk away* If you want to get your sister back, you must control the fire that burns inside. Only when you become a Crystal Gem, then will you be able to face...Mistress Quartz.
Ruby: Fine I'll do it, for Lapis
