#maybe cos Usopp actually admits he's an idiot he gets help

[potatopassenger]

Love that Nami ignores Zoro in his Loguetown predicament but when it's Usopp she intervenes

Nami about Zoro: That idiot will not ruin my peace

Nami about Usopp: Shit that's my idiot

My Sworn Brothers [Luffy x Crossover!Sister!Reader x Ace x Sabo]

A/N: Hey, so I want to write a High School AU of the many, many anime I have watched/ read. Bleach, Blue Exorcist, Devil is a Part-Timer, Durarara, Fairy Tail, Fullmetal Alchemist, High School of the Dead, InuYasha, Kill La Kill, Magi, My Hero Academia, Noragami, One Piece, Ouran High School Host Club, Pokemon, Saiki K, Sailor Moon, Seven Deadly Sins, Soul Eater, Sword Art Online, Vampire Knight, Your Lie in April, and Yu Gi-Oh. And I was wondering who would you like to be apart of your friend? And would you like to have a relation to any of the characters of the world. 

Summary: [Y/N] is the oldest sworn sister to Luffy, Ace, and Sabo. And after finding Ace and Sabo aboard Luffy’s ship, the Thousand Sunny, she explains to them who she is, her other sworn brothers and sisters, embarrasses the three of them (a regular Tuesday for her), and threatens them with a chalkboard for interrupting her. Multiple times. In this story, most of the anime I am into is in the same world (Bleach, Blue Exorcist, Fairy Tail, Fullmetal Alchemist, InuYasha, Magi, My Hero Academia, Naruto, Noragami, Seven Deadly Sins, and Sword Art Online.  I might do a part 2. 

Warnings: spoilers for the above mangas and animes, also, even though this is along the timeline of after the time skip (at some point), I took the creative liberty to have Ace alive during this meeting for a quad family reunion, might be language

“How the hell am I suppose to believe that my three idiotic brothers would be in the same place at the exact same time I’m trying to find them?” the girl with [H/C] hair, old enough to be Luffy’s age, maybe a year younger or a year older than him. 

“[Y/N]!!” the rubber boy flung himself at her in a hug.

She fell down on her butt from the impact of the hug. She groaned before pushing the boy off of her and standing up, dusting herself off. “Geez, Lu. I was on a job, just finished, and I heard something about a Straw Hat, a Fire Fist, and a blonde with a top hat that put the mad hatter to shame. I just came to see if the rumors are true.” 

“What job did you have, sis?” Sabo said as he sipped a smoothie created from Vinsmoke Sanji. 

“Well, you see. In the ten years I’ve been gone, I’ve been busy. Both with being lazy and being diligent.” the girl explained. “I am a member of Fairy Tail. Dragon Slayer Magic, particularly fire, water, earth, air, and plant. Requip the Knight. Some space jumping there and vortex opening here.” 

“You got the two mixed up, kid.” Ace said from his spot next to Sabo. 

The girl grinned an evil grin. “Oh, did I, Ace of Clubs?” 

The raven haired pirate groaned at the nickname while Luffy’s crew members wondered after the nickname. Ace kept giving her the don’t-tell-them-anything look with a cut-it-out motion. She, like most people she knew, did not listen to reason. 

“Well, when we were younger, I attempted to teach the pour unfortunate souls that you call Luffy, Sabo, and Ace golf. And we played mini-gold. First hole we went to, the club flew out of Ace’s hand and crashed into the window where the pour lady working the club stand was clonked on the head and fell unconscious. Another fun fact: I’m overly competitive and therefore master of mini gold. Luffy on the other hand... beat my bowling high score of just a little over four hundred points.” [Y/N] explained. 

“THAT’S NOT HOW YOU PLAY GOLF, YOU IDIOT!” Usopp shouted at his captain. 

“Ace was a lot worse. However, on the eighteenth hole, got a hole in one. Although with team sports, I always sided with Luffy ‘cuz he was the baby of the family.” she explained. 

“Never play Volleyball with her unless you’re Luffy.” Sabo warned the Straw Hat Pirates. 

“Could you... possibly.... explain who you are?” asked Nami. 

“That’s an easy and excellent question, m’lady. I am [Y/N] [L/N], the daughter of the Demon King from the Demon Clan, Niece of Solomon, adoptive daughter of the great dragon, The Curse of Depravity, a mage of S-Class ranking, the best older sister anyone can have, a Shinigami, and the Pirate Fairy.” [Y/N] said with her hands on her hips like wonder woman. 

“You’re not wonder woman, dumbass.” Ace muttered. 

She scowled at the boy (who was now physically older than her). “I know that, asshole.” Ace shrugged his shoulders at that. “Anyways, I should get going. I’m here with my teammates. And Salamander will have a cow if he finds out I’m on a Pirate Ship. Which may or may not include Natsu asking you all to fight him at once for his sister.” [Y/N] shrugged. 

“SISTER?!” Luffy screeched. 

“YOU ALREADY REPLACED US?!” Ace and Sabo said in unison. 

“This is why I never took you to Amusement parks or sat next to you on a ride.” she clenched at her swollen ears.  “No, I was merely saying that I have something called [Y/N]’s Council of Brothers. They’re basically a band of boys I feel need my protection, wisdom, and power to embarrass them until they’re six feet under and rotting.” 

“She’s dark.” Nami said. “But can you explain this whole Council of Brothers thing. Because I’m not sure they,” the ginger pointed to the three brothers, “understand.” 

“Alright! I will go over a lesson here!” and suddenly a white board appeared by her side with writing already on it. 

“Where did you get the white board?” asked Luffy. 

“That’s not important right now.” she scowled. “Yes, Sabo.” 

“Was that Whiteboard always there and we just never noticed it?” the blonde asked. 

“No. Ace if this is a question about the white board, I will smack you with the same gold club that flew through that window. All questions about the stupid whiteboard will be answered after I explained everything. Got it?” 

The three brothers grumbled out a, “Yes.”  

“Good. Anyways, to start it off I have two half-brothers. Meliodas and Zeldris.” she slapped a pointer stick against the whiteboard. 

“Did she always have that?” Ace asked, whispering it to his two brothers. 

“I don’t know. I’m just glad someone noticed it besides me.” Sabo murmured back. 

“SILENCE, YOU INSOLENCE FOOLS!” and she threw a frying pan which hit Ace in the head. 

Why does she have a frying pan in her requips? Sabo wondered in his head, not wanting to get hit in the head with anything else she might have to throw at them. 

“Anyways, Meliodas and Zeldris are my half-brothers. Zeldris is the captain of the Demon Clan’s ten Commandments while Meliodas is the captain of Liones’s Seven Deadly Sins of which I am co-captain and the Phoenix Sin of Darkness. To be fair, I look more like my mother and I think the only thing me, Meliodas, and Zeldris share is our dumbassery we inherited from our father. Second off, my cousin is Magi Aladdin since my mother is his father, Solomon,’s sister. Now, that’s enough of my actual biological family. Now, I won’t go into detail about those three. Because you already seem well-acquainted with one another. Anyways, onto the next one. The next one on my list of brothers is a half-demon named Rin who is the son of Satan along with his younger brother, Yukio, but he doesn’t really need protection. next is Kazuto Kirigaya also known as Kirito. I prefer to call him that. He got stuck in a game where if you die there, you die in real life, but he defeated them. next, we have Satan himself, a king of demons, Sadou Maou. He works as a part-timer for a fast food chain which is sad to be honest. Next, we have Alibaba Saluja, a prince and a king’s candidate, also my cousin’s best friend. He wields the fire djinn, Amon. Also, he’s trying to be a gladiator while figuring out his feelings for Fanalis and former slave Morgiana. Next, we have actual God Yato who is a former god of calamity and a current god of war. I think. I’m not quite sure. But he and his two regalia, Yukine and a Nora named Kazuma, but also Kazune under Yato, must be protected by me at all cost. Then, we have Edward Elric, a alchemist missing both a leg and an arm because he wanted to see his mom’s smile again which kicks me in the heartstrings whenever I hear it. His brother, Alphonse, is an honorary member of the Council of Brothers. And he used to be entirely a soul attached to a suit of armor. No joke.” 

“Does no one else notice that they are mostly raven haired or blonde?” Nico Robin commented. 

The Straw Hat Pirates turned to the three sworn brothers who just shrugged their shoulders at that. “I admit I am guilty for that. But my actual brothers are raven headed and blonde, so that may be the reason. Anyways, off to the next people. Now, this person could make Luffy look like a genius. Sometimes. Natsu Dragneel, a salmon haired fire dragon slayer, is the brother of Zeref Dragneel, the black wizard, and also simultaneously END, the most powerful demon of the book of zeref which makes him one of the top fifteen most powerful demons. Next, we have strawberry boi, Ichigo Kurosaki, a shinigami who I’ve been helping train. He could see the dead and then he discovered his spiritual power, stole the shinigami powers of Rukia Kuchiki, and started to exorcist hollows and send souls to the soul society. Then, we have my favorite band of brothers since they could literally be in a band. Broccoli Boi, Izuku Midoriya, kinda has a power augmentation quirk, best way to describe it without giving too much away, Porcupine Katsuki Bakugo who can blow things up with help from his sweat. Zuko Wannabe Shoto Todoroki who can wield fire and ice. Also, his brother Touya may or may not be Dabi. Then, Pikachu Kaminari Denki who can utilize elctricity, but too much and he makes Luffy look like a genius. No joke. Well… maybe… I don’t really know. Anyways, then we have speedster Tenya Iida. Oh, there’s sharkboy Eijiro Kirishima. He can make himself go as hard as rock, but he has limitations. Then, we have spidertape Hanta Sero that can shoot tape out of his elbows. Then, half-demon InuYAsha who is the son of a dog demon and a mortal woman. There’s also Shippo who is an adorable little kitsune. And I think I got everyone.” the girl looked at her board before smacking it again as she noticed Luffy had begun to doze off while Ace had totally fallen asleep. 

The action alerted the two boys to wake up at once and glare at their older sister. And then, a silver haired undead man with a flying blue cat landed on the floor of the ship. “Thank goodness we found you. C’mon. We got a mission and you and your ‘Team Natsu’ have a job request from the old man and a princess.” 

“So Hisui and Bartra both agree to have us do something, but what is this so-called mission?” asked [Y/N]. 

Ban smirked. “We’re fighting slave-trading pirates.” 

“I want in!” Luffy cheered.
