Author's Notes -
This is my first crossover fan fiction that I have written. For those wondering, it's a crossover with Sister Princess and Fullmetal Alchemist, two of my favorite series. I have not included Wataru or Akio in this story. Even though this is kind of a weird combination for an anime crossover story, I had this idea in my head for some time now, and I was always wondering what would happen if Ed and Al found out they had 12 little sisters. Note that I will use the English translations for what each girl calls her brother. I hope you enjoy this story.
NOTE – I do not own Sister Princess and Fullmetal Alchemist. They belong to their respective owners and creators.
Chapter 1 – An Island of Promise!
Two young boys, one with an metal arm and leg and one wearing a heavy armor suit, were about to go on a long journey to an island, where it is said that there is an incredible power that lies there. Edward Elric, a state alchemist, was quite interested in this task for it could lead him and his younger brother, Alphonse Elric, back to the way they lived before the event that changed their lives forever.
A few years ago, their mother, Trisha Elric, was sick and eventually died. Edward and Alphonse couldn't accept this fact, and wanted to find a way using alchemy to bring their mother back to life and to be with them again. They went to a faraway land where they met a teacher. The teacher was able to train the brothers on learning advanced alchemy. Once they completed their training, the two boys went back to their home, and tried what was forbidden in this world: human transmutation.
They had all the components they needed to create a full adult human body. However, when they actually tried to bring their mother back, they almost lost their lives in the process. Edward lost his arm and leg, while Alphonse lost his entire body. Also, they failed to bring their mother back to life. Instead, they brought something much worse. This type of alchemy was forbidden in this world, and they paid the price. They knew that they couldn't live in their house anymore, so they burned it down. They decided to go on a journey to find a way to bring their bodies back to normal.
There is a lone train in the vast ocean. It is heading to the island where the mysterious power is said to be. Edward was sitting still across from his brother, who was also resting, looking at the clean blue ocean thinking about the assignment that Colonel Roy Mustang has given him and his younger brother.
"Edward," Roy Mustang said. "I have an assignment for you and Al. It's about finding the Philosopher's Stone."
"Really?" the young alchemist said. "What kind of assignment is it?"
"We have a lead on where the real Philosopher's Stone could be. There is a strange source of energy that lies on an island. Right now, Hughes and I are finding more information on this island."
"I hope this isn't another fake imitation like the others we found. Have you found out anything?"
"Not much, Ed. The only lead we have right now is the location of the stone, and that is at the island. It's called Promised Island. Ever heard of it?"
"Not at all."
Colonel Roy Mustang continued, " Even though this island is uncharted on the map, it seems that there are people living there. I want you and Al to go to Promised Island and investigate. See if you can find anything about the power that lies there."
"Yes, sir. I'll tell Al right away and let him know."
"Good. I'll expect a report in about 2 weeks. The both of you start your journey tomorrow."
Edward left to tell Alphonse about the task that was given to them. Both of them were excited about this journey, hoping that their bodies would return back to normal. However, there were some things that Edward wasn't sure about. What kind of power lies on Promised Island, and what kind of people would he meet there? Could the Philosopher's Stone really be on this island?
Inside the train, Alphonse started to wake up and started thinking to himself if the people living there would react to his armor suit. He didn't want to think what would happen if they were to find out his secret about him not having a human body. Edward noticed his brother and asked, "Hey Al. What do you think we'll find on this 'Promised Island'?"
"I'm not really sure," the younger brother said. "It seems like a nice place from what you told me."
"Well, I hope to find the Philosopher's Stone so that I can get our bodies back to the way it was before. I promise you that."
"Ed?"
"What is it, Al?"
"Thanks for always being there for me when things get tough."
"No problem. The Elric brothers have to stick together, you know!" Edward said with a grin on his face.
After the long trip, they stopped at a small town. Apparently, they need to get on a boat to get to Promised Island. However, they would have to wait one day before they leave to their destination. Edward and Alphonse found an inn to stay nearby, and rested in the soft beds. It was a very long night. Edward couldn't sleep very well because he was thinking about what the island is like. He also wondered if someone was waiting for him there. He figured he would have all the answers tomorrow when they leave.
The next morning, the two brothers woke up and had a big breakfast to prepare themselves for the trip ahead. When they asked for a boat to get to Promised Island, an old man with gray hair surprised the Elric brothers.
"Well hello there, kids," said the old boatman. "Lovely day today, isn't it?"
"Whoa!" Edward yelled. "Don't surprise us like that! I almost thought you were an enemy."
"Sorry to surprise you, young man. Are you here to request a boat to the island?"
"Yeah," Alphonse replied. "We need to get to Promised Island so that we can get started on our job."
"I see," the boatman said. "Well then, it seems that I have a boat available for both of you. I just hope the boat will be able to handle a suit of armor."
Alphonse was not happy about this. What if the boat was sunk while they were on it? The old man continued, "I suppose I could borrow another boat that can handle the weight."
"Yes sir. That would be nice," Alphonse said.
"Very good. I will arrange a trip for the both of you now. Meet back here in about an hour."
"Thank you very much, sir."
Edward and Alphonse went back to the inn where they rested at. A few moments later, a young girl with green clothes and red hair went to the old boatman and wanted to go to Promised Island as well.
"Hello, miss. Are you here to request a boat to Promised Island?"
"Yeah," the girl replied. "I got enrolled to a school there." Of course, this was not the only reason why she wanted to go there.
"Very well. We have two other guests that will be joining you as well."
"That's fine. Thanks, old man!"
About forty-five minutes has passed, and another guest requested a boat as well. He seemed to be a bit weird, but the old man accepted his request. Once a hour has passed, Edward and Alphonse left the inn to get in the boat. When they got in the boat, they saw two other guests already there. The brothers didn't mind this, and the boat was now traveling to Promised Island.
As the boat was traveling, the young girl was thinking about the two brothers.
"So these two are my subjects, huh? They look pretty strange. What's up with the suit of armor? It looks like they're street performers or something."
After a while, Edward said, "Well, I think we should introduce ourselves. The name's Edward Elric, and this is my little brother, Alphonse."
The young man then said, "Well hello, Ed. My name's Yamada Tataru, but feel free to call me Yamada."
"Uh... sure thing, Yamada." A puzzled Edward said.
"So, Ed and Al, did you both get enrolled to Stargazer's Hill West University?"
"Not really," Alphonse replied. "We're here to complete a task that our Colonel has assigned to us."
"Oh, like secret spies? That is so cool! You know, I had a crazy life back in junior high. I had the best grades, was the most popular and funny person ever! I was even class president for three terms! Wow, Al. Is that a real armor suit? It looks so cool, but I wonder how you can walk in that heavy hunk of metal. Say Ed, what's that symbol on your coat?"
The Elric brothers have gotten bored of Yamada's conversation. After a while, he paused for a few moments.
"So who is this young lady?" Yamada asked.
"I'm Mami. Mami Yamagami" "Darn it! I wasn't suppose to reveal my name to these guys."
"Hello, Mami! I can see that the four of us will be really good friends very soon."
Edward and Alphonse were both pretty puzzled about this Yamada character.
"Man, this guy sure talks a whole lot. He's also a bit on the weird side," Edward thought. "And then there's Mami. She seems to be hiding something from us. I can tell from that look on her face. I wonder if she would know anything about the Philosopher's Stone at Promised Island."
After a while, the four characters finally reached Promised Island. Edward and Alphonse both grabbed their things, and started to look around this island. "I hope to see you two later," Edward said.
"See you later, Elric brothers!" Yamada yelled. Mami was mumbling something, and left to look around at another part of the island.
Edward and Alphonse went to a few stores to see what kind of items they have. These items varied from antiques to action figures. They talked to some people to know more information about the island or anything about the Philosopher's Stone, but they weren't of any help to them. They then decided to look around the school for any clues.
"Hey Al. Remember what that guy Yamada said about going to that school? I think we should check it out," Edward suggested.
"Yeah, I think so too. This place is kind of weird. No one really cares that I'm wearing a suit of armor."
As they went into the school, they notice a piano playing softly in the distance. They try to find out where it came from.
"Al," Edward said. "Do you hear that piano playing?"
"Yeah. It's a really nice song, brother. I wonder who's playing that."
When they finally found the location of the piano, they opened the door of the giant room, and saw a young girl playing the piano. She has long brown hair that was flowing with her as she played the piano. Edward and Alphonse couldn't take their eyes off of her. The girl noticed them staring, and stopped playing the song. She asked, "What are you two staring at?"
"Oh, uh... We just... You see..." Edward stuttered.
"We noticed the sounds of the piano nearby, and found you here. You're a really good piano player," Alphonse said.
"Thank you. It's a pleasure to meet you two," The girl said. "My name's Karen."
"I'm Alphonse Elric, and this is my older brother, Edward."
"That's strange," Karen said. "Shouldn't it be the other way around? After all, you are taller than him."
Edward was always a little sensitive about his height. He yelled, "What! Are you saying that I'm a little midget man that you can step on!"
"Calm down, brother," Alphonse said. "I'm sure she didn't mean it like that. It's just a misunderstanding."
Karen laughed, "Of course not. I wouldn't make fun of your height like that. Anyway, I have to be going now. There's someone special that I'm waiting for."
Karen walked passed the two brothers and said, "I hope we meet again someday."
A couple hours have passed since Edward and Alphonse first set foot here at Promised Island. They both didn't find any clues that might lead them to the source of the power in the island. Both of them realized that they haven't eaten in a long time. They both went to a train and saw the whole view of the ocean. It was a very lovely scenery. Alphonse noticed that another girl was sitting nearby at the train. She seems to be cold and putting her hands close together. This girl has short light brown hair, and looks like someone who was very fond of flowers. Alphonse said, "Hello. What's your name?"
"Hi. My name is Kaho. What's yours?"
"I'm Al, and this is my brother, Ed. You look kind of odd. Is there something wrong?"
"Well, I want to go to this cafe in the island, but I have no idea where it is. I could use a warm drink right about now."
"Perhaps we can use that map nearby." Alphonse took the map and looked for the cafe. It was close by, so he told to the old man riding the train, "Excuse me, we're stopping here."
The three of them got out. Alphonse explained to Kaho where the cafe was, and she thanked him for that.
"Thanks a lot; you really helped me out. I hope to see you again soon." As she started to run to the cafe, she tripped, and yelled to them, "I'm a klutz, but you should always never give up!" She smiled as she left.
"Weird girl," Edward said quietly to Alphonse.
Edward and his brother went to a restaurant nearby. Using the money that they have, they had a big plate, and their stomachs were full from the feast. Once the brothers went outside, it was getting dark, and Alphonse and Edward realized that they don't have a place to stay at. They went to an inn where they can rent a room, and then an old man appeared and surprised the brothers once again.
"Whoa!" Edward yelled. "Aren't you that old boatman that led us to Promised Island?"
"What on earth are you talking about? I'm just a old man who owns an inn here. Are you two looking for a room?"
"Yes. Do you have any available?"
"It just so happens that I have no rooms available."
Edward gave out a frown. "Well, this stinks. It looks like we're on our own, Al."
"But of course, I can give you a place to stay elsewhere."
"Really? Where's that?"
"It's at a place called Welcome House. It's a really big and nice place that guests stay at, and I can let you rent it for a special price."
"Wow. Thanks a lot, old man."
Edward and Alphonse had the key to Welcome House, but figured they would look at one last place for any clues before they called it a day. They found a store nearby, and asked some people about the stone. A voice then said, "Hey, can you help me with this?"
"All right," Edward replied.
"It seems that I can't zip up my dress. Can you help me?"
"Yeah, sure."
Edward was a bit embarrassed by this, hoping that no one saw him zipping the girl's dress. Little did he know, that Mami was watching him and Alphonse close by. After the dress was zipped up, the girl revealed herself and asked, "Well, how do I look?"
"You look pretty nice, miss..."
"My name is Sakuya."
"I'm Edward Elric, and this is my brother, Alphonse."
"Wow. What's with the suit of armor? Isn't it hot inside?"
"Yeah it is, but I'm used to it," Alphonse lied. He didn't want to expose his secret to her; not in front of all these people.
"Well, I'm off," Sakuya said. "There's someone I want to show off this dress to. I'll see you two later." She gave a wink as she left.
After Edward bought the clothes he wanted, it was time to go stay at Welcome House. The Elric brothers followed the signs, and saw a sign up above that says "Welcome House" on it.
"Well Al, this is our new home," Edward said in amazement.
"This house is pretty big. A whole family can live here." the younger brother said.
"Wait a minute. I notice that the lights are on. Could someone be there already?"
Edward and Alphonse walked up to the door feeling a little nervous about who was in the room, and opened the door. "Welcome home, Big Brother!"
"Huh?" Edward said confused and shocked. There are three girls standing, waiting for their big brother to arrive. Surprisingly enough, these girls are Karen, Kaho, and Sakuya.
"Didn't we see you guys earlier?" Alphonse asked.
"Well yes we did, but we wanted this to be a surprise for Big Brother," Karen said.
"I helped set up the decorations in the room for you, Brother," Kaho said.
"It was your idea to surprise Dear Brother, wasn't it, Karen?" Sakuya asked.
"Yes it was. I want to give this to you, Big Brother."
Karen gave Edward a very nice watch. Edward thought it looked very expensive.
"Thanks a lot. It looks very nice."
"You're welcome, Big Brother."
"But, how can this be?" Edward said, still in amazement. "I only have a younger brother, and now you're telling me that I have three younger sisters?"
"You forgot about me, Bro-Bro," A young voice said.
The little girl came downstairs. She was wearing a cute yellow dress. She was a person who likes teddy bears a lot.
"Hiya, Bro-Bro. My name is Hinako."
"I'm Ed, and this is my younger brother, Al."
"Wow, you're really short, Bro-Bro."
Edward got into his anger mode once again, "What! Why you little... I'll show you who's short!" Alphonse grabbed him so he wouldn't hurt anyone.
"Hi, Hinako," Alphonse said. "It's great that we got to meet all of you again, but how can you be certain that Ed is really your older brother?"
"We have been waiting a very long time for Big Brother to show up, because he's been away for some time now. I'm so happy that we're reunited again," Karen said in a sweet voice.
Edward was confused over the whole situation. "How could Mom not tell me about this? Are they really my sisters, or do they not know who their real brother is? I don't get it. I was only here to find any clues on finding the power that could be the real Philosopher's Stone. And now I find out that four young girls are my sisters? I bet someone set me up!"
Just outside, Mami was watching the whole thing happen from a bush nearby.
"How can this guy be so confused?" Mami said. " I thought it was pretty obvious from the beginning. Well anyway, pretty soon he'll want to leave the island, and then it's game over!"
Edward figured that he needed some rest from all this, and hoped that it was some kind of dream he was having. As he stared at the moon from his bed, he began to think about his mother, who was a kind and caring person to both Edward and Alphonse.
"Brother," Alphonse said. "Are you still awake?"
"Yeah I am, Al. What's the matter?"
"Do you really believe that we have four younger sisters?"
"I don't know, but the most important thing right now is finding the Philosopher's Stone. I can worry about my 'sisters' later. It's getting late. Good night Al."
"Good night, brother."
Edward looked up in the moon again, and thought to himself, "Mom, I hope you are doing okay. You must be really surprised as well to find out that I have four younger sisters. Well, no matter what happens, Al and I will restore our bodies back to the way it was. I swear it." Edward shed a tear in his eyes, and went to sleep.
Next Chapter: Edward and Alphonse has started to get used to living with the sisters. However, mysterious things starts to happen at the house, and there are eight more younger sisters! Also, why is Mami keeping an eye on Edward and Alphonse? Who is really behind all this? Find out in the next chapter: Big Brothers, I Love You Very Much!
