This is the third One Piece x My Hero story that I made. The first one is the one that started at all with Straw Hat Vigilantes, the second one is my interpretation of Straw Hats plus the most popular My Hero Academia fanfiction of all time Apotheosis with The Straw Hats and the Infinite Gauntlet. However this time it will be different.

How about a world where the characters of One Piece live in the My Hero world. Luffy is the age of the characters of 1-A and goes to UA, become a hero not because he wants, but because he has all this power and he doesn't know what to do. Also this is a major AU luffy, I want him to be like a modest teenager, but don't worry we will see inches of our Luffy from there and there.

Also, I want this also to be a harem fic. I have some One Piece girls already pic for him for the story, but what about the My Hero Girls, who should I put.

Now about the ages, backstory and what is the deal with one piece characters is something for another chapter. Luffy quirk you can figure out, what about the others? What are their quirks? Now let's get this one on the road.

On a different dimension

The world of heroes

Monkey D. Luffy was just an average middle school student, he was from Romance Dawn Middle School where he studied with his best friends: Ronoroa Zoro, Nami, Usopp and Vismoke Sanji. They were on his last year of Middle School and they need it to know where they were going after that.

''Man I am bored.'' Said Luffy walking out of school.

''Well Luffy not every day is a fun chasing adventure. Sometimes school life is not the most exciting.'' Said Nami.

''Things should be easier for now. Once we are done with middle school I can focus on the world swordsmanship tournament.'' Said Zoro.

''What about we think of our high school life for now?! Most of us don't have a plan.'' Said Usopp.

''Lets grab some snack at Makino's. We can clear our heads there.'' Said Sanji.

The group had the habit of going to a popular place called Makino place. Run by a woman who used to be Luffy babysitter when he was a kid. It was very popular among teenagers and young adults.

Makino Place

The group soon arrived and were greeted by a young woman with green hair.

''Hey Makino.'' Said Luffy.

''Oh hey Luffy, everybody. Please take a seat that I will be there in a second.'' Said

Luffy friends were regular costumes, since Luffy and Makino knew each other for years she used to give them nice discounts on the food.

''Makino can we have the usual?'' Asked Luffy.

''Sure, coming right up.'' Said Makino.

''Can I have some booze this time?'' Asked Zoo.

''Zoro-kun I told you no underage drinking on working hours.'' Said Makino.

''Fine.'' Said Zoro rolling his eyes in annoyance.

Makino soon brought some sodas and burgers to the group. They really were grateful for all the hard work that the woman did every day.

''Makino-chan you are truly an angel that came down to earth.'' Said Sanji going all smooth over Makino.

''Oh thank you Sanji-kun.'' Said Makino laughing.

''Enough with flirting at this time!'' Said Nami pulling Sanji ear to make him stop.

The group decided to eat their lunch in peace as they think of what they should do. While eating they stop some UA students also in the place.

''UA in here? Cool, its been a while since I saw someone from there in here.'' Said Usopp.

''We could apply for the regular course and get some money with the upcoming heroes. We can bet in the future of some rookies.'' Said Nami.

''Of course you would bet someone life over money.'' Said Zoro.

''I still don't understand why the big deal. I mean we have enough heroes, why the need of more?'' Asked Luffy.

''It's not hard to see why most seek to become heroes. Its like the equivalent of being a super movie star or a five-star chef. You can get money, fame, women, connections and women with just that.'' Said Sanji.

''You said women twice.'' Said Luffy while he ate his food.

''Well being a hero is underrated. I mean you could be a hero since your quirk is really powerful, plus you inhuman feet's. I could also think that Zoro and Sanji could be hero material.'' Said Nami.

''I am a swordman and not a hero. I would rather cut my arms than put a stupid ass costume.'' Said Zoro.

''Well I am flattered that you think me as a hero Nami-swan, I am a chef and that's what I am mostly focused. If I was a pro, I would have to think of my duties rather than preparing a meal.'' Said Sanji.

Luffy was on the other hand still thinking of what he should do next. He didn't know what step to take and what he should do with this power that he has.

''Luffy what are you doing? Are you thinking?'' Asked Usopp.

''I don't know. I am just so lost! Like what should I do? I never had a plan because I thought High School would take forever.'' Said Luffy worried.

''So what kind of profession you wanna go inn?'' Asked Nami.

''I don't know, a hero.'' Said Luffy saying the first thing that popped in his head.

The group just laugh at that. Luffy being a hero was something that they didn't expect to hear or even think about it.

''You a hero! Luffy we love you, but we don't know if the hero world is ready for you.'' Said Sanji.

''Maybe I can have a shot and then quit halfway. I don't know I have nothing else in mind. I don't want join the marines like gramps.'' Said Luffy.

''What about your brothers? They have things figure out.'' Said Nami referring to Ace and Sabo.

''They're doing their things; this is my life so I need to think for myself.'' Said Luffy.

''What kind of hero would you even be? You like to disobey rules and do what you please.'' Said Usopp.

''Its not like I would follow the book; I would do things my own way and have fun along the way.'' Said Luffy.

''So you would be a related hero?'' Asked Nami.

''Maybe.'' Said Luffy.

Then while the group was talking someone arrived to greet them. A tall woman with white/green hair, big red horns and massive breast. Also, she was wearing a UA uniform.

''Hey there guys. Nice to see you in here at this time.'' Said the second-year girl named Yamato.

''Oh Yamato-chan.'' Said Sanji.

''Nice to see you all in here.'' Said Yamato taking a seat with the group.

''Yamato are you off to school now?'' Asked Usopp confused.

''Yes, I was taking Tama home and decided to eat something.'' Said her.

''So how is the new school year right now?'' Asked Nami.

''Hard! If I thought the first year was rough, second year is even worst. Is like they want to punish you for keep going on.'' Said Yamato all tired.

''Second year in the hero course is that bad?'' Asked Zoro.

''Since people either drop out or a send to other course those who remain have to endure training that was fit for 20 people in total.'' Said her.

''So what are you complain about? Aren't you super strong?'' Asked Usopp.

''I am strong, but I am not made of diamonds. I still get my butt kicked around sometimes. Anyway, what are you guys talking about?'' Asked Yamato.

''Luffy was thinking of taking the hero course.'' Said Nami.

Yamato blinked in surprised to hear that, Luffy the Luffy taking the hero course.

''Luffy! For real! This would awesome, you can internship with me and even be my sidekick!'' Said Yamato with a little blush.

''I am not decided yet. Besides, I want to see what path I like. Also, I am nobody sidekick.'' Said Luffy pissed making Yamato giggle.

''Well what would your hero do?'' Asked Nami referring to a man named Shanks.

''I don't know, Shanks is still traveling the world doing whatever he does. I haven't talked to him in months.'' Said Luffy.

''Shanks is a pretty busy guy, I mean when you have a monopoly at your hand you will be busy for years.'' Said Yamato knowing what the Red haired man was all about.

''I don't know.'' Said Luffy.

The group was taking about a man named Shanks. Who saved Luffy from drowning when he was a kid and Luffy said he wanted to be just like him. Well shanks was strong, had a kind weak quirk, but for Luffy he was one billion times cooler than All Might and Endeavor put together. He was always traveling the world with his company ``Red Haired Inc`` doing all kind of investments and other deals. Little did they knew about what Shanks really did under the shadows.

''Luffy, you should put more thought on what you would do in the future. High School is a pretty big deal.'' Said Nami.

''Whatever, I will see what I can and maybe I will find something that I like.'' Said Luffy.

''Well its not just you. Like I am also trying to see what I will be. I mean Zoro is aiming for world championship, Nami on the Weather, Sanji on the restaurants and even Yamato is a heroine. We all need time to think on our future.'' Said Usopp.

''We are not going this deep tonight. Lets eat some burguers, maybe some milk shakes and call off the day.'' Said Luffy.

''I am not paying your bill this time guys. Lets have some more cokes and chat a little bit.'' Said Yamato.

''Well well high School gossip, that's sound interesting.'' Siad a older woman voice.

Soon the group saw an older woman with fine figure, short dark hair and a spider shirt.

''Hello kids.'' Said the woman known as Shakky, the previous owner of the bar.

''Miss Shakky you are already here.'' Said Makino seeing the older woman.

''Oh Makino have you made my drinks?'' Asked Shakky.

''Yes, they are right here.'' Said Makino.

''I will be there on a second. So what are you kids talking about?'' Asked Shakky.

''We are thinking of our high school life and how we have no clue on what to do.'' Said Zoro.

''Well high school is a place where you find yourself. I had that when I went through my time, you either find your purpose or have a little path to what you wanna do. Either way is an experience that you don't want to forget anytime soon. Just think about it kids, this is the last year of middle school so you can find something in the way, how is that about?'' Asked Shakky.

''Wow, really good advice as always miss Shakky.'' Said Luffy with a smile.

''I try.'' Said her just laughing.

The older woman went to the bar have her drinks while group kept chatting and thinking on what is going to be their high school life.

''So how Luffy, hero or not?'' Asked Nami.

''I don't know. Maybe I flip a coin and see where this goes.'' Said him.

''A coin! Seriously!'' Said they in shock.

Shakky and Makino just laugh at that as they listen to the conversation.

''A hero? Either Luffy would be the greatest hero or the one that would speak the truth.'' Thoguht Shakky as she drinks.

The group decided to just keep chatting about other subjects and Yamato would always tell on how awesome her hero work has been. Ever since she had started working under the number 9 hero Ryuku she has been getting a lot of attention lately. She hoped that Luffy would become a hero, not only because the world would really benefit from someone like him helping out others, but because she wanted him to be close to her.

Later

The group was finishing their lunch, they were still talking about what they are going to do with their high school. Then a new person arrived, someone older and she wanted to talk with the black-haired student.

''Oh Luffy-kun.'' Said a beautiful woman with raven hair, white skin and sunglasses. It was their history teacher Nico Robin.

''Nico-sensei!'' Said the group of Romance Dawn Middle School.

''Please, we are out of school. Call me Robin, it makes me feel old.'' Said Robin.

''Oh ok, but that's is a bit weird.'' Said Nami a little confused.

''Luffy its good to see that you have a good social life, but you need to focus more on your studies.'' Said Robin a bit serious.

''How much did I took in the last test?'' Asked Luffy a bit nervous.

''Let's just say you need to study a bit more. I know you are strong, but grades are also a really important feature for a good high school to choose you.'' Said Robin.

''Sure, I will try…I can even ask nami here to teach me.'' Said Luffy.

''I am not cheap.'' Said Nami with a smirk.

''Poor man is going to ended up poor.'' Said Usopp.

''Oh well good to see that you aren't just jokes and goofing off. You can take things seriously, see you in class Luffy-kun. You guys also.'' Said Robin leaving.

The teacher was a complete mystery, she was dubbed ``The most beautiful teacher``, but there was some kind of enigma that she was laying around. Something that the group wasn't liking, but Luffy didn't mind that.

''That woman always give me the creep.'' Said Nami.

''Yes, I don't know what is her deal.'' Said Yamato.

''You tell us. You don't have class with her, its like she has eyes everywhere.'' Said Usopp nervous.

''Robin-sensei is the best teacher ever. Show some respect!'' Said Sanji.

''Of course you would go to her side pervert.'' Said Zoro.

''I don't know guys, despise her being all creepy and sinister I think she is a really good person.'' Said Luffy with a smile.

The group just looked confused at that. Luffy had that tendency of knowing when someone was good or bad, this was something that was calls back since he was a little kid. In fact, Luffy was a very ``special`` person, but this world didn't know yet.

Robin just laugh at the teen group and went to her sit in the bar next to Shakky as Makino went to grab her order.

''So Robin-chan what are you having?'' Asked Makino.

''Oh nothing special, I have class tomorrow.'' Said Robin with a smile.

Robin just looked at the group again with curiosity, specially Luffy. She felt…something about him that was difficult to express.

So yes, this is the first set piece of this world. Nobody ever did a teen One Piece Au setting on the My Hero academia World. I want Luffy to be like some of those AU where he is a goofy teen, but still not to the point of being dumb as a brick. Here he got actual education and learned a little bit. He is like the Luffy from a lot of teen AU that I think are very fun to read.

Also, I want to make this into a harem fic. Which girls should I put here for Luffy? Can be One Piece girls, My hero girls. You can see that we already have some contenders.

Quirks ideas give to me. Also, I am thinking of putting more students on class 1-A and 1-B. Which One Piece characters should I add to make things even?

Well see you all later and stay tuned for a new chapter.
