"LUFFY BEST BOI" - All Might Muscle Form, Anger

After the events that happened during the Joint Training Camp, the 1st year and 3rd year Hero Course were given a free day which the two batches of students were happy about

Class 1-A wanted to do everything they planned during the free day so all of them went out of the dorms to do whatever they planned to do, but some people remained in the dorms

"Is there someting interesting to do?.." Luffy said while pouting, he was lazily laying at the couch in the Class 1-A's common's room while watching T.V, Luffy was obviously bored out of his mind "What should we do? Broccoli Hair?"

Along with our favorite rubber man was our favorite cinnamon roll, Izuku Midoriya aka 'Broccoli Hair'

"W-well, I didn't expect for all of them to go out..." Izuku said and sat beside Luffy who was laying on the couch

All of Izuku's classmates went out for the day to either visit their families, to train or went out of town to relax and enjoy their one day vacation, Izuku remained because he had already visited his Mother last weekend and he didn't want to train because he thought that he should spend his time to relax for a whole day for a change, training too much isn't good for body after all

"By the way, where's Law-san? I haven't seen him, did he went out too?" Izuku asked to Luffy

"Ohhhhh, Torao went to a Teacher's meeting or something, I don't remember SHISHISHI" Luffy sheepishly said while scratching, Izuku nodded in understanding and began to think

"I wonder what the Teacher's meeting about... I'm sure the teachers are having a meeting to discuss the events that happened during the Joint Training Camp..." Izuku deeply thought

Izuku continued to think but was disturbed on his thoughts when he heard a long sigh

"haaaaaaaaaah~ I'm soooooooo bored... I wanna play... I wanna eat... I wanna go on an adventure..." Luffy lazily groaned as he shifted frantically on the couch before flopping his body on the couch

"I miss my crew..." Luffy uttered quietly with a hint of longing and sadness in his tone but was loud enough for Izuku to hear

Izuku looked at the man beside him with a worried look, he knew that Luffy was a pirate so as a pirate he must have his own crew and Its no wonder that he misses them

"Luffy-san must be feeling lonely right now without his crew by his side..." Izuku thought sadly, suddenly an Idea dawned on Izuku's mind and he began to smile widely

"Hey, Luffy-san" Izuku called the laying rubber man from the couch who slowly turned to him while pouting

"Why don't you tell me about your crew while we go on an 'Adventure' of our own around the school?" Izuku said happily to Luffy who stood up Immediately when he heard the mention of his 'crewmates' and 'Adventure'

"REALLY?! I'LL TELL YOU ABOUT THEM SO LET'S GO ON AN ADVENTURE RIGHT NOW! BROCCOLI HAIR!" Luffy said while jumping excitedly, Izuku chuckled as his plan to cheer the Rubber man up was a success

"Wait a moment Luffy-san, we have to prepare ourselves first! let's eat so we won't starve when we're going out and take a bath after that!" Izuku said to Luffy who nodded happily in reply as they head towards the kitchen to eat, Izuku cooked Luffy some food which he happily devoured and complimented Izuku for his cooking skills which made Izuku embarrassed, after eating, they went to take a bath and meet each other in the common's room again and left the dorms together to go on an 'Adventure'

Izuku and Luffy were walking beside each other around the School Campus, the school was almost empty with a few students here and there because the teacher's declared that this day was a free day so the student's must've went out too

Luffy told Izuku how he always gets lost in the school because of how big the place is which made him late in the class sometimes, Izuku could only chuckle in reply and told him that he'll give him a tour around the school so that he can memorize the places around the school

"So Luffy-san, can you tell me about your crewmates now before we arrive to our first destination" Izuku said to the Straw Hat wearing man who just looked at him before grinning

"Sure Broccoli Hair! I promised after all! My crewmates are Zoro, Nami, Usopp, Sanji, Chopper, Robin, Franky, Brook and Jinbei! I recently recruited Yama-o and Carrot on board our ship before me and Torao got here!" Luffy said cheerfully to the Curly haired teen who was silently listening to Luffy with a smile

"My First crewmember is Zoro! he's an amazing swordsman and he uses three swords! THREE SWORDS! one in each hand and one in his mouth!" Luffy excitedly said to Izuku who was surprised and had his mouth agape when he heard from Luffy the details of his first crewmember

"T-THREE SWORDS?! AND ONE IN HIS MOUTH?! T-That doesn't sound safe at all..." Izuku honestly said to Luffy who just smiled for Izuku's concern for his crewmember

"Don't worry about him! Zoro's super strong! and he's gonna become the Best Swordsman in The World one day!" Luffy said with a proud tone as he told Izuku the dream of his friend and crewmate, Izuku was silent as he was in awe at the person that Luffy had told him, Zoro's grandiose dream reminded him to Luffy's own dream which was becoming the Pirate King, which according to him was the 'Freest man in the world'

"Wow... he's incredible..." Izuku could only utter quietly as he learned about Luffy's first mate as Izuku thought that Zoro's probably a strong and admirable man

"SHISHISHI, he REALLY is incredible!" Luffy said with a wide smile "Next! My second crewmember is Nami! she was a Thief who hated pirates but she eventually joined me and became my Navigator when I beat the shit out of the Pirate who's making her and her Village suffer!" Luffy simply said but remembering what Arlong had done to Nami and her Village was making him visibly angry, Izuku who noticed the change of Luffy's demenour and emotions, Izuku panicked and tried to gain Luffy's attention again

"R-really Luffy-san? she's wonderful for caring about her Village!" Izuku said nervously as he tried to cheer Luffy up which he was able to do because what he had said made the rubber Man smile and began to talk again

"Yep! She's an amazing Navigator and her dream is to draw the Map of the World! the world where me and Torao came from was SUPER BIG~! Nami told me that there were no complete maps which documented our whole World there so she decided that she'll be the first person to draw the Map of the World!" Luffy excitedly said to Izuku who was smiling happily

"Heeeeh" Izuku hummed in astonishment as he began to Imagine what kind of world did the two of his new friends lived what wonders their world had to offer

"And my third crewmember is Usopp! he's a liar but an amazing sharpshooter! he can hit you with his cool slingshot everywhere you go! his dream is to become a Great Warrior of the Sea!" Luffy said with sparkles in his eyes as he complimented his friend and crewmate while Izuku was silently nodding as he listened to Luffy's stories about his crew with a smile

"And the fourth member is Sanji! HIS FOOD IS AMAZING YA KNOW! HIS FOOD IS THE BEST THING I'VE EVER ATE! he's the best chef I could ever ask for! also he's super strong too and only uses his legs in battle!" Luffy excitedly said "His dream is to find this cool sea called All Blue which according to him contains all delicious sea food ingredients from all around the sea!"

Izuku was still silently listening with a smile while thinking about Luffy's crew fondly "Luffy-san's crewmates sounds like they're amazing people..."  Izuku thought

Luffy continued to tell Izuku about his crewmates, Izuku was surprised when he heard from Luffy that he had a cool Transforming Tanuki Reindeer named Chopper in his crew and the said Transforming Tanuki Reindeer was a Doctor! Luffy told him that Chopper's dream was to cure all known disease which earned a wide smile on Izuku's face and silently began to support Chopper with his goal

Luffy then told Izuku about Robin, who was their enemy at first and works from a Enemy Boss who made their friend's country suffer, Luffy being Luffy beat the shit out of that Boss and saved Robin who wished to die back then and chose to join him on his adventure, Luffy told Izuku that Robin's dream was to find some stones named Poneglyphs and read the carvings on that stone so she would learn about the 'Lost History' which Luffy didn't understand himself, Izuku didn't know what Poneglyphs and what the Lost History are but he gave his full-support for Robin and prayed that she could find what she's looking for

The next crewmember that Luffy told him about is a Cyborg named Franky, "A-A-A CYBORG?!"  Izuku was excited when he learned that Luffy had a Cybernetic Human in his crew and was extremely excited all boys of all ages love Cyborgs after all, Luffy told him that Franky was the Best Shipwright and the one who built their 2nd ship named Thousand Sunny, which means a bright ship that could overcome and sail Thousands of seas! Izuku was astounded by that he really wanted to see Luffy's crewmates and what their ship looked like but he was dejected because it was impossible to do... Luffy then told him that Franky's dream was to build a dream ship that could circumnavigate around the world and could set sail on any sea, Franky managed to build such ship which Luffy said was the Thousand Sunny but Franky didn't want to come with them at first but he was convinced when he got his balls clutched by Robin's power... Izuku had his mouth hanging from this and Instinctively covered his own pair

Luffy then told Izuku that he had a living skeleton named Brook in his crew, A SKELETON! Izuku shivered about this but Luffy reassured him that Brook was a cool, strong and an amazing guy who can play any Instrument you tell him to play! Izuku was amazed by the living skeleton's talent, Izuku then asked about the reason why Brook was a skeleton, Luffy then became sad and told Izuku that Brook died a long time ago and that his soul came back to the world because of his Devil Fruit power and came to look for his body, but when Brook's soul found his body, it was nothing but bones and his Afro, Izuku began to get sad for Brook, Luffy then told him how he met Brook, and how he became his crewmember, Izuku smiled happily for Brook who had finally found the reason on why he chose lived that long, It was for him to meet Luffy and his crew... Izuku was beginning to tear up, Luffy told him that Brook's dream or rather a 'promise' was meeting an old friend that he had left long ago after he died, Brook promised to meet him again and was still keeping that promise even when he died... Izuku began to cry for Brook, Luffy comforted Izuku and said that Brook is fine with them now and that he's still keeping his promise with his 'old friend' which made Izuku smile

Luffy then told him the next member was a Fishman named Jinbei who he had met when his brother was imprisoned, Izuku noticed that he was uncomfortable while telling his story and said that he didn't have to tell him about that but Luffy reassured him that it was fine... Luffy then told him how his brother got caught, how he was sent to the most dangerous prison in their world and tortured and how his brother died saving him... Izuku was teary eyed again as he listened, losing someone important to you is hard and is something that is difficult to accept, he knew what that feels after Sir Nighteye's death... Luffy told him that Jinbei was the one who helped him and encouraged him when his mind was a mess after his Brother's death and Luffy told him that he swore and made a promise with himself that he'll definitely recruit Jinbei if they see each other again, Luffy told Izuku that Jinbei was able to join him officially recently during their fight between the 'Yonko' which Luffy said to be the Four Strongest Pirates of their world, Izuku was trembling with excitement because he already knew that Luffy and his crew was able to defeat the so called 'Yonko' and not only one but two of them! Luffy told Izuku that Jinbei's dream was for Humans and Fish-men to coexist which made Izuku emotional again and silently cheered for Jinbei

Luffy then told Izuku the latest additions to their crew which was Yamato and Carrot, Luffy told him that Yamato was the son of one of the Yonko that they defeated which surprised Izuku, Luffy told him that Yamato was always beaten by his father and came to hate him, Luffy told him how Yamato was inspired by the samurai guy named Oden who chose to literally replace him by being Oden himself, Yamato wished to join Luffy on his adventure and Luffy didn't even need to think and let him joined them, Luffy told Izuku that Yamato is strong and was a great help during the 'Battle of Onigashima' and he and Yamato were already friends so It was great that he could join them, Luffy then told Izuku that Yamato's dream was to open the borders of the WanoKuni, the country that was shackled by one of the Yonko that they defeated

Luffy then told Izuku about Carrot, which Izuku thought was a weird name to have because its a Vegetable... Luffy told him that Carrot was a Rabbit-man who belonged from the races called Minks, a humanoid race with animal features who become super strong during the full-moon! Izuku was bewildered by this and was very interested about her, he also understood why she was named as Carrot because It's probably because she's a Rabbit, Luffy told him about Carrot's dream which was simply to set sail out of the seas, Luffy told him that Carrot was always stayed in her country which was at the back of a thousand year old walking giant elephant, Izuku was very fuckin' surprised of course but he still kept silent and listened to Luffy, Luffy told him that Carrot's adventurous spirit grew and she began to have an Interest to the sea and wished to set sail one day, Izuku told him that when Luffy and his crew arrived at their country it was overrunned by the underlings of the Yonko they defeated so they of course help them, Luffy then went out to save his friend, Sanji, who had left them because he was being threatened by his 'Father' and was able to save him with the help of his crewmates and Carrot, Carrot accompanied them until Onigashima and when the battle was over, Carrot begged Luffy to let her join him which confused Luffy because he had considered her as a crewmate to begin with, which made Carrot incredibly happy

"Wow..." was all Izuku could say after Luffy finished telling him the stories about his crewmates

"SHISHISHI! they're the friends and crewmates that I'm really proud of! they're my family and an irreplaceable treasure to me..." Luffy simply said with a fond smile

Izuku was starting to feel tears forming in his eyes as he then looked up to Luffy

"Luffy-san, I hope you and your crewmates achieve your dreams one day!" Izuku said with a wide smile, his watery eyes enhanced the color of his emerald eyes, his freckled littered cheeks was accompanied by a tint of pink and the morning sun shined upon him which made him look like an Angel

Luffy was taken a back at what Izuku had said before grinning

"Of course! and I know you'll become a great Hero that you've always dreamed of, Broccoli Hair!" Luffy said to Izuku with a wide grin

The tears that formed on Izuku's eyes soon fell on his cheeks as soon as he heard Luffy said that to him, Izuku always believed himself that he could become a hero, even when everyone else thinks he couldn't, he didn't stop believing himself, he persevered and became All Might's successor with his Persistence, Tenacity and Efforts, hearing someone's support was a new feeling to him because of his background and even though he managed to enter U.A, he couldn't help but think he was lacking, he felt that he was constantly left behind by his peers,

But he always made an effort and trained hard, harder than anyone else, to make his dream come true and to make All Might, his Idol, His Hero proud. Hearing that Luffy was genuinely supporting him and his dream made him emotional and began to cry quietly, Luffy saw this and was confused before walking up towards the crying teen and hugged him

"L-Luffy-san?..." Izuku shakily said while tears was still falling on his eyes, he was baffled by the Straw Hat wearing man's actions

"When you want to cry, you can cry on my shoulder, I'll lend my shoulder to you because we're friends and comforting friends is what friends do." Luffy simply said with a smile as he continued to hug Izuku which made Izuku emotional once again and tightly hugged Luffy back and began to cry loudly on Luffy's shoulder

It took Izuku a couple of minutes to calm down and began to wipe his eyes and face with a towel that he bought before apologizing to Luffy

"I-I'M SORRY LUFFY-SAN! I EVEN STAINED YOUR YUKATA WITH MY TEARS I'M REALLY SORRY!" Izuku said while bowing repeatedly to Luffy who just laughed loudly at him

"It's fine, Broccoli Hair! I'm just glad that you're fine now!" Luffy said with a grin, Izuku stopped bowing and smiled widely at man in front of him

Izuku then noticed that they've already arrived at their destination, he then called Luffy's attention

"Oh look! I didn't even realize were already here Luffy-san!" Izuku said as he pointed out at a Large Door that is probably made of steel, Luffy stared at the door with child-like curiousity and began to get excited

"This place is called the Support Department, this is a place where students from Support Course develop and make Support Equipments for Heroes to use!" Izuku explained to Luffy who just continued to stare at the door of the Support Department Lab with stars over his eyes

"THIS PLACE LOOKS SO COOL~! DO YOU SEE THAT HUGE DO-!" Luffy was loudly complimenting the place when suddenly...

'BOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOM!!!' the huge steel door in front of them was destroyed when a loud explosion happened

"EEEEEEHHHHHHHHHHHHH?!" Luffy yelled his eyes and mouth wide open, he was surprised when the place Izuku had shown to him was now covered in smoke because of the explosion

"uhhh not again Hatsume-san..." Izuku thought and mentally sighed, Izuku then turned to a surprised Luffy and forced a smile

"hehe... Luffy-san calm down, It's ok, these explosions are a daily occurrence..." Izuku wearily explained as he calmed Luffy down

"NANI?! you mean those loud explosions happen daily? THATS SO COOL~!" Luffy got over from his shock and was amazed by the 'daily occurrence of the explosion's Instead, Luffy and Izuku then heard a voice inside the smoke covered room

"How many times has it been this week? Hatsume?!" a rough sounding voice irritatedly said while coughing

"Fufufu... as I've always told you Power loader-sensei, FAILURE IS THE MOTHER OF SUCCESS! even if the things I made didn't work the way I've wanted them to work, what I did was not a waste of time at all!" a feminine voice full of optimism cheerfully said

The thick black smoke started to clear and Luffy and Izuku finally saw the two people who owned the voices, the first person was a short and skinny man who wore an excavation claw on his head and the second person was a short girl who had a pink hair which is styled into a dreadlocks, yellow eyes and Irises that are shaped like crosshairs, and steampunk-themed goggles that was donned to her head

"Power Loader-sensei! Hatsume-san! Hello there!" Izuku said as he ran towards the two and greeted them, the two people noticed his presence and greeted him back

"Ohhh, Midoriya, Hello there, what did you come here for today? did you came to have your Hero Costume Upgra-" Power Loader was about to finish when he was cut off by the pink haired girl who appeared in front of Izuku which surprised the curly haired teen

"MUSCLES! why are you here? are you here to make babies with me again or have your Hero Costume upgraded?" the pink girl named Hatsume asked to Izuku as she also invaded his personal space making poor Izuku a blushing mess, embarrassed

"H-H-HATSUME-SAN PLEASE DON'T SAY SOMETHING THAT PEOPLE WILL MISUNDERSTAND!" Izuku said while blushing madly and distanced himself to her, Hatsume just laughed loudly and began to chat with Izuku again

Power Loader just sighed at Hatsume's antics and noticed that Izuku was with someone and looked to see Luffy

"Oh? Hey Midoriya, who's this guy right here?" Power Loader said and gained the attention of the two and they turned to looked at Luffy too

"Oh! Sensei let me Introduce him to you! He's a new 3rd year transferee student here named Luffy and I'm showing him around the school right now!" Izuku said and then turned to Luffy "Luffy-san, this is Power Loader-sensei the Excavation Hero! and this girl is Mei Hatsume, a student from Support Course and my friend!" Izuku said as introduced he the two to Luffy

"Hello there young man, My real name is Higari Maijima, you can call me Maijima or Power Loader, whatever you like" Power Loader said to Luffy, the pink haired girl then stepped forward and began Introduce herself to Luffy

"I'M MEI HATSUME AND I'M THE WOMAN WHO WILL SOMEDAY BE ABLE TO CATCH A COMPANY'S EYE AND MAKE THEM BUY AND SPONSOR MY SUPPORT EQUIPMENTS AND I WILL BECOME THE BEST INVENTOR IN THE WORLD!" Hatsume loudly exclaimed, the pink haired girl's determination and energy made Luffy smile widely

"I see! My name's Monkey D Luffy!" Luffy said as he Introduced himself to the two, Izuku was about to talk again when Luffy Interrupted him

"AND I'M THE MAN WHO'S GONNA BECOME THE PIRATE KING! Nice to meet you! SHISHISHI" Luffy chuckled happily, Izuku's felt his heart drop and ran towards Luffy with in speeds that could even put Iida to shame

"LUFFY-SAN!!!!!!" Izuku whisper-shouted at Luffy who just began to laugh loudly

"Pirate King?" both Power Loader and Hatsume said confused while tilting their heads

"A-ah! It's nothing really!" Izuku said while waving his hands frantically to the two of them

"Well if you say so Midoriya, Anyways if you want to go on a tour, why not let Hatsume accompany you?" what Power Loader said made Hatsume turn to him with a shocked expression

"EHHHHHHHHHHHHH?! WHY POWER LOADER SENSEI? I STILL WANT TO MAKE BABI-" Hatsume's whining was cut off when Power Loader spoke again

"Hatsume, I know that you really love to make and create things but It's not bad to take a break... you should care about your well-being for once, and since the Lab was destroyed by your 'Baby' again I'll have no choice but to close it for now and repair the room" Power Loader said which made Hatsume pout

"O-okay Sensei, I'm also sorry for breaking the room..." Hatsume apologized which made Power Loader nod happily

"Umu, It's fine Hatsume, Just relax for once, I'll tell you when the Lab's already repaired so don't worry." Power Loader said which made Hatsume smile widely

"Thank you Sensei!" Hatsume bowed as she thanked her teacher and went towards Izuku and Luffy

"So... Muscles and Straw Hat guy, can I come with you two?" Hatsume asked

Luffy and Izuku could only look at each other before smiling as they both turned back to her

"Of course!"

It was already evening when Luffy, Izuku and Hatsume finished their 'Adventure' Luffy and Hatsume came to get to know each other and Izuku with the help of Hatsume managed to show Luffy around the school and the most Important thing was they were happy, Hatsume was able to rest and relax her mind for once

"HAAAAAAH, that was fun!" Hatsume breathe a tired sigh "I should do this for some time again!"

"Hatsume-san, Don't forget to sleep properly and don't stay Inventing in the Lab's all day okay?" Izuku reminded Hatsume, Izuku knew she was all ways locked up in the Support Department's Lab Inventing so he told her that she should move her body around time to time and rest when she knew her body needed it

"I get it already Muscles, jeez" Hatsume casually replied to him but it really made her happy that he was worried for her

"That was fun~! It took us all the day to be able to explore this school! as I've said before this place is BIG!" Luffy said happily as he was satisfied with his adventure with Izuku and Hatsume

"Since It's already night time, I gotta go back to the dorms! see ya again Muscles and Straw Hat guy!" Hatsume happily said as she waved goodbye to the two of them and went back to her dorms

Luffy and Izuku waved back and said take care to her, they too began to return back to their dorms

Luffy and Izuku reached the dorms and saw that the Lights were opened

"So they're already here!" Izuku thought with a smile as he and Luffy walked inside the dorm and they saw Izuku's classmates, his second family, all gathered in the common's room

Izuku along with Luffy walked in and was surprised when they heard the class scream

"MIDORIYA!/DEKU!/IZUKU!" his classmates yelled out to him and was tackled by them

"HEY MAN WHERE DID YOU GO? YOU DIDN'T RESPOND TO OUR MESSAGES SO WE THOUGHT SOMETHING HAPPENED TO YOU!" Kirishima exclaimed with worry as he continued to hug the curly haired teen

"HE'S RIGHT MIDORI~! WHERE WERE YOU?" Mina said while ruffling Izuku's fluffy curly hair

"SO YOU'RE HERE ALREADY NERD I WAS ABOUT TO CALL YOU! STOP MAKING PEOPLE WORRIED FOR ONCE DANGGIT!" Bakugou hollered at him as he shoved his phone inside his pocket before grumpily walking away

"Welcome back Midoriya" Todoroki monotonously said but he was happy when he saw him

Izuku was then crowded by his worried classmates, Izuku could only smile fondly, he had friends now and he has the power to make his dream come true, he really was blessed.

"O-oh sorry guys! I forgot to bring my cellphone when I was with Luffy-san earlier!" Izuku replied to the worried Kirishima

"Heeeh... But where did you two go?" Uraraka asked to Izuku

Izuku and Luffy only looked at each other before smiling widely

"On an Adventure!"

(gonna start the new arc soon!)
