Chapter 19: Mewnipendance Day

Star had invited several of her classmates, Miss Skullnick, Marco's Sensei, her brothers, and two other people, one was a young woman with short orange hair, and the other a man wearing a mask with long blue hair.

Of course they were all talking amongst themselves with the majority of the group unsure why they were there.

"Quiet everyone! Quiet!" yelled Star, "I assume you all brought your swords!"

Everyone stared at her.

"Yeah… I was confused about the invitation." Said Alfonzo holding up the invitation.

"I wasn't." said Miss Skullnick holing up hers, "This is clearly meat, I came for the meat."

"I told everyone to bring swords!" said Star showing off the sword she was holding.

"Don't worry." Said Ace jabbing his thumb at a barrel full of swords, "Me and Deuce brought plenty of swords!"

The masked man nodded, he was Masked Deuce, Ace's first mate.

"Thanks Ace! You're a life saver." Said Star.

"Yeah I think everyone's just wondering why they're here." Said Marco.

Star sighed.

"IT's the 37th of Gravnogk." Said Star, which earned stares from everyone but her brothers, "Mewnipendance day!"

"Star… Earth uses the same calendar as the Blue Dimension." Reminded Sabo.

"Wait how is that even possible?" asked the orange haired woman.

That was Koala, Sabo's newest member and liaison to the Revolutionary Army.

He decided to bring so she could get used his family… and not because he had crush on her…

Okay… maybe a little...

Star sighed, she had totally forgotten the fact. So she went upstairs and came back down with a Lil' Golden Pop Up Book and began to give the history of Mewni.

"Long Time ago arrived the first settlers of Mewni. In pursuit of Life, Liberty and Corn." Explained Star.

"Corn?" asked Masked Deuce.

"Mewmans love their corn." Said Ace with a shrug.

"But the wicked monsters rose up and attacked he innocent Mewmans and the re-steal Mewni for themselves." Said Star, "So the Queen used her magic to turn the simple peasants into a fearsome army."

That was when Star quickly got through the next part.

"And there was fighting, fighting, fighting, fighting, fighting." She said pushing through this portion, "And we won!"

She showed off the last page of the showing off the castle.

"But wait you blew past a lot of the important stuff." Said Marco.

Sabo looked at Marco and knew he had to talk to him.

"When do we eat?" asked Miss Skullnick.

"After we reenact the great monster massacre." Said Star, "Now please split into two teams: Monsters and Mewmans."

"Can be a Mewman?" asked Miss Skullnick.

"No you're a monster, that's why I invited you." Said Star.

Koala and Masked Deuce looked at Miss Skullnick.

"She's our teacher, Star accidentally turned her into a troll a while ago." Said Marco.

"Why did you your brothers only bring one member of their crews?" asked a girl who was dressed like she was trying to be Star.

"It's my time hosting a Mewnipendance Day celebration I wanted to keep it small, make sure there wouldn't be too many drunken shenanigans… and avoid the Johansen Monster Massacre Reenactment of 5 years ago…" said Star.

Star, Ace and Sabo all shuddered.

"I still don't know why Lump did that to a spear." Said Sabo.

"Sabo… we agreed to never talk about that again." Said Ace.

As thy chose sides, Star grabbed Marco, "You get to my general." She said.

"Thanks." Said Marco.

Everyone slip into teams, with Sabo, Koala, Janna, StarFan13 (the girl who was trying to look like Star), Francis and Sensei taking the Mewman side.

And Luffy, Ace, Masked Deuce, Alfonzo, Ferguson, a kid named Ed and of course Miss Skullnick taking the monster's side.

"Looking good, looking good! Now we have to make costumes then after that: THE BLOODBATH CAN COMMENCE!" she suddenly yelled, "Hey Janna I might need your help creating the costumes."

"Fine…" muttered Janna.

"Question." Said Marco.

"Yes." Said Star.

"What is that!" said Marco.

He was talking about a large floating eyeball.

"Oh that's the all seeing eye." Said Star, "It proves to monsters that the Butterfly family is always watching…"

"I can't be the only one thinking one weirdass holiday." Said Masked Deuce staring at the All Seeing Eye.

Miss Skullnick slapped him.

"What the hell!" yelled Masked Deuce.

"Sorry… force of habit." Said Miss Skullnick realizing that the person who just swore was pirate and not one of her students.

And so they all got ready for the monster massacre reenactment.

Star was stuffing a pillow down Ferguson's shirt with a swords

"Here! This way your entrails don't become your out trails!" said Star.

She then stabbed his pillow and it lost cushioning.

"Hey Star…" said Marco a in a gigantic suit of armor, "Hold on let me remove this."

He removed the helmet.

"I've been looking through the book and something seems off." Said Marco.

However due to the fact that Marco's armor was gigantic she couldn't look at the book, so he dropped it and she picked it up. She looked at the battle going on. And realized something.

"You're right Marco, I can't believe I didn't see this before." Said Star.

She turned her wands to the Mewman team and began altering their weapons to be more fearsome and giving Francis as a unicorn to ride on. Then she vanished the monster side's weapons.

"Hey what do we get?" asked Ferguson.

"Use your claws! You're monsters!" said Star.

"I know Monster's are evil, but doesn't this seem a little unfair." Said Marco.

"Unfair?" asked Star.

That was when StarFan13 accidentally dropped her mace on Ferguson. With him writhing in pain.

"So sorry Ferguson!" cried StarFan13.

"Somebody do something! He's writing in pain." Said Alfonzo.

Then Ferguson stopped.

"Never mind he stopped…" said Alfonzo.

Ace and Masked Deuce began to get he mace off him.

"Hey!" said Miss Skullnick to Luffy, "You and the two have to make sure we don't get killed."

"Okay." Said Luffy with a shrug.

"Hey… Marco… we need to talk." Said Sabo.

Sabo pulled Marco aside.

"Marco, just letting you know that history is not Star's strong suit." Said Sabo.

"I take history class with her." Pointed out Marco.

"Oh yeah…" said Sabo, "But my point is the history between Mewmans and Monsters is complicated."

"Do you mean actually complicated or "My dad's an emotionally abusive jerk and I don't want to talk about it"?" asked Marco.

"Actually complicated." Said Sabo.

"Oh…" said Marco.

"The Mewmans did take the land from the monsters in a very bloody battle, but the monsters have done equally horrifying things. It's an endless cycle of hatred and misery."

"Did something happen recently?" asked Marco.

"Somewhat recently." Said Sabo.

He couldn't help but think back to the day he first read about it…

(Flashback)

It had been a couple of weeks after Sabo moved into the palace. It had been a boring princess lesson day so he decided to spend his day in the library.

And yes there was a reason why he called the "boring" princess lessons, as some of her lessons were learning how to fight and Sabo was allowed watched these lessons.

And thankfully going to the library wasn't as boring as he thought.

He hated his island's history mostly because it was A. Small island in the east blue and B. The noble's just droned on and on about their abolishment's on the island, but Mewni's history was actually interesting.

The queens, the history of various alliances, the wars between Monsters and Mewmans. It was interesting.

It really did keep him entertained during Star's boring Princess lessons, and yes there was

However the book he was reading that day was more about recent history… the stuffed he learned made him want to ask Queen Moon something.

Turned out she had decided to check in on him.

"Hello Sabo." Said Queen Moon.

"Hello." Sabo replied politely.

"I just wanted to see how you were doing." Said Queen Moon.

"Oh fine." Said Sabo.

"Good." Said Queen Moon.

She noticed the book he was reading… it was about a fairly recent monster war.

"Queen Moon I wanted to ask you something…" said Sabo.

"What?" asked Queen Moon.

"It doesn't have anything to do wit the wars…" said Sabo who began to blush a little, "What was it like to have a mother who loved you."

"What?" asked Queen Moon honestly caught off guard.

"The pictures of your mother… all of them have her lovingly looking at you." Said Sabo.

He showed off the page showing off a painting of a beautiful Purple haired woman looking loving back a small baby who was tugging on her dress.

"Oh Sabo I'm sure your mother loves you." Said Queen Moon.

"She doesn't…" said Sabo, "I once got into a fight with another boy… he pulled a knife on and me. She fretted over him while I was the one injured."

Queen Moon could tell he was leaving something out, but other than could tell he was telling the truth.

Sabo looked down, she wasn't expecting a hug from the Queen.

"I'm sorry…" she whispered as she began to cry.

The two of them stood silently.

"She was a wonderful mother… she always found time for me, even with everything she wanted to do for the Kingdom." said Queen Moon, "And I miss her everyday."

"I'm sorry for asking that." Said Sabo.

It's okay…" said Queen Moon, "I was thinking of baking some pies with Star today. If you want to join you can…"

"Really?" asked Sabo.

"Of course, you are sworn bother after all…" said Queen Moon.

Sabo nodded.

"I will see you later." Said Queen Moon, "There's something I have to speak to River about."

Queen Moon left the library with tears still in her eyes. Sabo went back to reading the book, realizing that he just became close with the queen.

(End of Flashback)

"Star's Grandmother was a very kind queen who strived to make peace between Monsters and Mewmans. It got so far as a treaty was drafted to finally bring peace." Said Sabo.

"What happened?" asked Marco.

"A monster general by the name was Toffee murdered her in cold blood during the signing." Said Sabo.

Marco paled concededly, "Star doesn't know anything about this does she?" asked Marco.

"She doesn't… in fact she thinks that when the Queens retire they go to the Grandma farm to play with other Grandmas." Said Sabo.

Marco stared at Sabo.

"I have no idea why she thinks that…" said Sabo, "And something tells me she didn't get it from Luffy."

"So…" said Marco.

"Moon should be the one to tell her…" sighed Sabo, "But I felt you should know at least."

"I see…" said Marco.

"Come on… Star needs her general…" said Sabo.

"Yeah…" said Marco.

"Also I can't believe I had to explain this twice today…" said Sabo.

"What?" asked Marco.

"A little bit of advice when it comes to girls… if you're going to a family get together that might remind her of why she joined the Revolutionary Army tell her longer than a day in advance about what the day is about…" said Sabo.

"What…" said Marco again even more confused.

"Just never mind…" said Sabo.

The two head back to where the battle reenactment was going and everything looked fine.

Marco saw that Star was staring sadly at the pop-up book.

"Hey Star… we're ready for your signal." Said Marco, "Unless you changed your mind and we can eat now…"

"No… no… it will be fun…" she replied rather unsure of herself.

"Okay…" said Marco, "Let's battle."

They went to prepare for battle.

"Knights of Mewni!" called out Star, "Take off your stabby weapons and drive off the evil monsters!"

Star sent out a large purple skull into the sky using her wand and the battle reenactment began.

As it was brutal Ferguson decided to becoming invisible and hide in a tree.

However it should be pointed that his costume resembled Buff Frog.

Not only that but Buff Frog showed up as part of another plan to steal the wand.

Though ironically StarFan13 almost crushed him thinking he was Ferguson.

Star watched the battle in horror, the reenactment was completely one-sided. Really the only ones on the Monsters side that had weren't having problems were Luffy, Ace and Masked Deuce and that was because of their skills and powers.

She didn't notice Buff Frog using a mace of some kind trying to steal the wand.

However whatever it was didn't' seem to work.

SO he tried to grab it, however Francis' unicorn knocked him away hard.

Star watched in horror as this happen.

She grabbed her wand.

"Ferguson!" cried Star as she used her wand to fly into the air and land next to Buff Frog, "Ferguson! I'm sorry! Marco is right! This isn't fair! Ferguson! Are you okay?"

"I'm fine!" said Ferguson in the tree he was hiding in, "I'm just invisible."

Everyone nearby stared at the real Ferguson then looked at Buff Frog. Buff Frog pushed Star away and began to run away.

Star pointed her wand at him as he fled. However as he fled she didn't attack him.

Realizing the truth of that day really shocked her to the core.

"All right! Let's go eat some corn and meat!" said Marco.

"Hey you okay?" asked Luffy.

"I'm fine…" said Star.

"Come on let's go eat the meat for Skullsy eats it all!" laughed Luffy.

"I heard that!" yelled Miss Skullnick.

They all ate a dinner of a mixture of meat and corn.

Durring dinner Marco was having a conversation with Koala about karate. She smiled at the two then noticed Buff Frog on a tree looking very sad.

She decided to give him an ear of corn.

Star walked back to the table.

"Star…" said Sabo.

"yeah?" asked Star.

"Remember your ancestors did do something bad… but they've also done a lot of good." Said Sabo.

"You knew the truth didn't you?" asked Star.

"You know I enjoy learning Mewman history." Pointed out Sabo.

"Oh… right!" said Star, "Come on let's eat some corned beef."

"You're still aware that has nothing to with corn right?" asked Sabo.

"I know." Said Star.

With that Star realized the truth about the founding of Mewni… a day that would change her perceptive… and not only that but also the start of a wonderful friendship with someone very unexpected.

Next Time: Luffy, Star and Marco deicide to experiment with the Scissors and see if they would take them to an island that's not in the East, West, South, North Blues or the Grand Line. Good news: It takes them somewhere. The bad news: Not only are men forbidden on the island but Luffy gets seprated from Star and Marco... Can it get worse? Oh looks like he angered the empresses and now she's going to execute him... What will happen find out next time!
