Hello Hopeless Blue Kiss here with a new story for you. This is a fusion of My Hero Academia and Katekyo Hitman Reborn! I own neither of the anime but had phone writing both. I see very similar parallels between the main protagonists Tsuna Sawada and Izuku Midoriya. So, I thought what if Izuku was trained to become a mafia boss? I thought it'd be a cute concept for a harem fic with Izuku being the main love interest. I hope you enjoy and review to show your support.

Bocchan Mafioso

"Hit the ball Deku!" shouted out a male classmate.

The greenette cringed at that nickname, but tried his best to see where the softball was to smack it over the net. He wasn't the athletic type. The greenette preferring to bury his face in books and laze about than sweating and moving. So, when he tripped over his own shoelaces trying to follow his classmate's instruction it was just the universe rewarding him for going against his own nature. He nearly bit his tongue as his chin hit the unforgiving ground, grunting when the softball smacked the back of his head to add insult to injury.

Groans and jeers could be heard from his fellow classmates complaining about having to be stuck with him on their team again. He didn't want to be there in the gym either. It was not lost on him as he rolled clumsily onto his back, that no one bothered to see how he was. He rubbed his jaw, wincing in pain before stumbling to his feet. He swayed, looking hopefully at his teacher to see if they would dismiss him from further strenuous activities. But his homeroom teacher, Aizawa-sensei was busy looking at his phone screen.

Izuku inwardly sighed and prepared himself to get back into the game when a smelly dust rag smacked him in the face as the school bell rang. "What the—" He said in muffled alarm. Then peeled the dust rag off his face to the soft snickering of some of his classmates. "Since you lost the game for our team again, the least you can do is clean up by yourself while we go outside to have fun after school," insisted one of the male students. The others chirruped in agreement, one shoving a broom in his hands, looking barely apologetic as they took off running and horsing around. They laughed and said in loud whispers about the bad luck of being stuck with Deku again.

"You're such a problem child. You're not athletic. You don't apply yourself when it comes to your tests. You get easily distracted in my class. You don't stand up for yourself when you're clearly getting used. I know you have hidden potential somewhere Midoriya. But I can't want you to do better more than you do. Apply yourself even if it's a little at a time," Aizawa-sensei, said in a tired, but kind voice. He gently patted the high schooler's shoulder in sympathy before departing from the gym, his face once more buried in his phone.

Izuku Midoriya stood their in shock as he watched his teacher leave him there by himself in the gym. He knew his teacher was right. He was nothing more than a no-good Deku. He wanted to argue that he wasn't a 'Deku', but it didn't help that his name could be read that way. Or that he was 'useless' and 'powerless' when it came to classroom tasks and interactions. There was no positive spin you could put to that horrible nickname or the situations he found himself in. All he could do was shoulder the burden he was given and push on the best he could as he began to sweep up and put away the sports equipment.

He was sore and tired by the time he had finished tidying up the large gym. This wasn't the first time he had been abandoned by his classmates and forced to clean up after him. He moved slowly as he dragged himself into his house and tucked his shoes away at the front door. The only highlight of another disastrous day was that he got to see the school idol Ochaco Uraraka walking with her friends and she actually waved back to him when he lifted his hand in a half-hearted wave. The immediate embarrassment he felt when her friend Camie asked in a hushed voice if she knew him and her shaking her head 'no' still didn't stop that moment from being a highlight to his day.

"Mom, I'm home," he announced as he slipped on his house slippers.

"Izuku, sweetie, I heard from your teacher that you are close to flunking your grade if you don't stop ditching class and apply yourself. You were such a good student before your dad moved overseas for a better job," Inko said in a worrying voice. She dutifully followed behind her only child as he trudged up the stairs, a plate of cookies in her hands. "I know you miss your dad, but what are you going to do in the future if you allow yourself to flunk all your classes, sweetie?"

"What's the point in going to school anyway?! It's not going to bring my dad back?! He had us move to this new place two years ago and just abandoned us for a new 'job'. He probably has a whole family over there by now," Izuku whined throwing himself on the bed, to faceplant against his many pillows. He bit his lip, ashamed that he let that much escape from him, when he wanted to keep his mother in the dark. But he couldn't stop speaking even if he wanted to, feeling relief in finally airing everything out. "If he doesn't care about us, why should I care about my future."

Inko was stunned into silence looking at her petulant child. It had been a while since her son had mentioned her husband Hisashi and his clear absence I their lives. She had honestly thought that he had gotten used to the video chats and regular phone calls and texts. But it was clear that his grades and attention to detail outside of his comic books was a direct result of missing a father figure. He was such a daddy's boy even though he smiled and pretended he was okay with everything.

"Oh Izuku, I'm sure his work will transfer him back to us soon. Just be patient and in the meantime you shouldn't just let your grades fall because you are upset. What about friends? I know it's been two years, but I haven't seen a friend visit here. Surely you have made a friend that you can confide in?" she questioned, encouraging him to open up.

"They call me Deku, because I'm useless," Izuku grumbled, turning his smooshed face to the side to look sullenly at his mother. He didn't clarify who the 'they' were, but he was sure his mother could understand it through context. He wasn't usually this sulky and emotional, but he had noted his dad's marked decrease of calls and text. As well as feeling slightly bitter that nothing went right in his academic life. "I can't wait until high school is over, so I don't have to deal with classmates and homework."

Inko let out a deep sigh before squaring her rounded shoulders. "Sweetie, what you need is a tutor. Look, I found this in the mail," his mom said excitedly, wanting to change the subject.

"Will raise your kid to be the new leader of the next generation. Grade and subject doesn't matter," Izuku read aloud as he sat up and looked at the colorful flier. Words like 'home tutor' and 'future leader' stood out to him before he sneered and balled up the flier. "I don't need this. It looks like a scam. I refuse to have a tutor."

"Your home tutor is coming today whether you like it or not. I don't care what you want Izuku, how saw your grades you hid under your bed. Your teacher was being generous when he warned me about your grades. You need serious help and I am not taking no for an answer mister!" she declared, hands on her hips, the plate of cookies set already on his desk. "Those cookies are for our guest when he comes."

Just then the doorbell rang and Inko squealed in excitement, already knowing who it could be. She gently smoothed out her apron before opening the door. Her cheeks flushed as she looked at the Italian gentleman on her doorstep.

"Ciaossu! I am the home tutor, Yagi Toshinori, here to make your son into a future leader," said a tall, skinny blonde man, with piercing blue eyes and a booming voice. He was dressed in a steal grey, expensive here piece suit with a lavender pocket square and a single suitcase. He had taken off his fedora and rested it over his chest as he graciously bowed to the mother. He then took a step forward, apologizing for intruding before taken off his shoes as the mother suggested.

"Sorry, it's a Japanese custom," she said as she quickly found Hisashi's slippers for the older man to wear in order to step further into her house.

"It's no problem. I am a guest in your house after all. You said you could offer a spare room, correct? I don't want to intrude on such a lovely home

"No, no, you are fine. I'll show you to your room first and then I'll show you to my son who needs all the help he can get," Inko said conversationally as she guided the blonde guest up the stairs.

Izuku could hear their muffled words through his bedroom door. But refused to peek his head to look at the man that was intruding into his home. The last man that had entered his home was the plumber and before that his absentee father two years ago. He couldn't believe his mother was being so trusting of a stranger that could easily rob them while they were sleeping, just because of a flier. He pretended not to care about the door opening to his room, his face buried in a random comic book.

"This is my son Izuku Midoriya. He means well, but he has been acting out and getting bad grades because he misses his father," she said in a confidential whisper. Then clapped her hands over her mouth realizing that her son might not want that last little tidbit. "I'm sorry 'Zuzu."

"MOM!" Izuku exclaimed, cheeks flushed in embarrassment and anger. He was already feeling slightly raw and vulnerable letting it slip earlier how his dad's absence coupled with their move were the main reason he gave up trying to do well academically. It was one thing to finally let his mom know the reason, but another to let a complete stranger to know that he was a whiny baby that missed his daddy.

"Young Midoriya, I Yagi Toshinori and I am here to whip you into shape!" the skinny man, declared, kindly ignoring the mother's confession. He stood stoically, hands on his hip, a gleaming smile flashed his way amid his distress.

Izuku didn't know what to do with that. Should he be grateful or reproachful that the man didn't acknowledge his failings. "Um…" he said intelligently, when the man offered his hand to shake. It was a very western gesture and Izuku stared at the hand a minute too long before the clearing of his mother's throat prompted him to take the man's hand to shake. "Are you're in the right house? I don't think we can afford your services," Izuku confessed eyeing the expensive watch, fedora and three piece suit.

"That is nothing you should worry about Young Midoriya. I invest well to afford these little trinkets. I assure you and your mother that my services are almost a steal. Let's just get started in making you into a future leader, kiddo. Ms. Midoriya, you can go now. I'm sure you have other things to tend to and I need to start whipping your boy into shape," the blonde man said kindly, gently encouraging Inko to leave.

Once she was gone, the smiles and jovial disposition was gone as he rounded on Midoriya and looked analytically at the young high schooler with a tired sigh. He moved over to Izuku's computer chair and took a seat and a thoughtful bite of his cookie, all the while looking thoughtfully at the teen. After a long, pregnant pause, where another cookie was consumed, the man stood up and straighten his lavender colored tie. "I'm going to be straight with you kid. My true line of work is as a Mafia Boss and I'm training you to be my replacement, he said grimly.

"What! A Mafia boss? Are you kidding me?!" Izuku cried out in surprise. Of course his luck was so rotten that his mother invited a lunatic to come in stay with them. Either this grown man was crazy or a criminal. He wasn't sure which one was worse as he took a step back from the man and tried to be as discreet as possible as he eyed the door. He wasn't the fastest, but he was sure he might be able to make the door before the grown man did.

"Sit!" said Yagi, with the authority that broached no room for arguments. He waited until the teen's legs gave out from under him as he weakly sat on his bed before the older man continued, hands folded in front of him. "You might not believe this, but you belong to a long line of mafia members. No… no, let me speak before you interrupt. Your great, great, great, grandfather on your father's side was the first mafia boss of the Midoriya bloodline. Your father, Hisashi, is aware of both of your mafia connections, although like you, he seems to refuse his heritage. We tried to track him down and he offered you as a prime candidate saying he was to set in his ways and that you were more malleable being younger," Yagi

"M… my dad sacrificed me?" Izuku said weakly, his eyes widen in surprise.

"It's less of a sacrifice and more of an honor. People literally died to get to where I am. Usually, I might even send someone out in my place to teach and guide you. I am a Mafia Boss. I should be leading my organization and making sure there are no screwups. But every time I pick an heir to my organization and an instructor to teach them, both end up dead before the heir could take over," he confessed sheepishly in a heavy Italian accent.

"Wait… wha—" Izuku tried and failed to process what this man was telling him. He clearly heard him mention mafia more than once and he understood what they were. He just didn't understand why having a great whatever meant that he should be forced to now have this burden that his father himself clearly managed to dodge. "Are you serious?" he squeaked out.

"As a heart attack, Young Midoriya. But don't worry, with my tutelage you'll make a fine Mafia Boss yet," the blonde man said reassuringly.

"Dinner's ready

"Wait, you can't just leave after an explanation like that," Izuku spluttered out, jerking his hand back from the man's immaculate suit.

"As much as I'm glad that you are interested in learning more about your new role, I did travel from Italy to Japan. It was a long journey, and I wouldn't mind a homecooked meal where I don't have to worry about possible poisoning," Yagi said apologetically as he left out Izuku's bedroom door.

"Poisoning?! Even more reasoning on why I can't accept this role!" he exclaimed as he followed the Italian down the stairs. "They call me Deku for a reason," he said vehemently. He petulantly marched down the stairs. The high schooler nearly smacked his face against the older man's back as the blonde gave pause on the stairs.

"My Japanese isn't the best, but do you want to be a Deku all your life? Do you want to be useless and powerless? Someone who will let others' define you because it's easier?" asked Yagi solemnly in a neutral tone, his body still facing forwards on the stairs.

"N…. no. I hate being called and thought of as a Deku. But it's h… hard breaking from that nickname," he confessed, scrunching up his face in frustration. His mind quickly thinking of the softball game earlier that day and how others were quick to label and use him so easily. Even when he tried to be more it seemed like for every step forward he took two giant leaps backwards.

"Then you'll accept your role as my heir and prove that you are a capable leader that isn't useless," Yagi said firmly, a broad smile displaying on his face as he turned his head and winked at the teen. The skinny man nearly jogged down the stairs, chuckling boisterously as Izuku squealed out in indignation.

"I didn't say that either! Don't put words into my mouth!" he cried out. He was thundering down the stairs behind his elder hoping to catch him and do what, he wasn't sure. But he was determined to get this man to understand that he was not meant for the criminal lifestyle. Yagi's felt like he was telling the truth and the truth was scaring him.

"I see that you two are already the best of friends," Inko cooed, happy to see her son so lively. She sat down a steaming bowl of fried pork cutlets over a bed of fried rice with diced spring onions, peas and carrots. It was followed up but a bowl of salad in case the main meal wasn't to the tutors liking. The thirty something year old woman had been worried at first how her young son would respond to another man in the house. Especially someone who would take such an active role in molding and tutoring him during his formative years. But it was clear she had nothing to worry about. She smiled and offered Yagi a nice helping of Katsudon along with her son, knowing it was Izuku's favorite. She could tell he was momentarily mollified by the way he quickly took up his seat, his protests silent for the moment.

"This looks amazing Ms. Midoriya. My compliments to the chef," Yagi said politely as he skillfully used his chopsticks to take a tentative bite. He hummed in pleasure, loving the flavors that burst on his tongue and it was all that he could do not to ask her for the recipe for his cook at home.

"It's just Katsudon," Izuku mumbled grumpily. He pouted; hand fisted into the hair of his bowed head. He was happy that his mom was getting compliments. But it still felt awkward that it was coming from a man that supposedly ran a Mafia family with dangerous people including himself. He didn't want that anywhere near his mother, but there wasn't much he could do. 'I could try calling the cops, but would they believe me,' he thought anxiously pushing around his perfectly cut pork cutlet. He honestly didn't have the bandwidth to deal with these kinds of problems.

"Oh hush, you love your Katsudon. Eat, eat, you're a growing boy," Inko insisted, dismissing her son's sullen behavior. Izuku was a growing boy and with that came teenage angst and outburst of rebellion. Her round cheeks were still flushed in being complimented by the very skinny, but still clearly handsome foreigner. He was so exotic and European that she worried her bottom lip wondering if it would be rude to request a picture with him to show her friends. She opened her mouth to ask when there was a sudden thunderous banging on their front door. "Oh, were we expecting someone else?"

Izuku looked owlishly up at his mother before narrowing his eyes suspiciously at Yagi before an angry voice accompanied the ferocious banging.

"Where the fuck is Deku! I heard the boss wants to train him and I should be the one he trains! All Might should be training me!" came a muffled voice from the front door.

"All Might?" mouthed both Midoriya's. Green eyes both turned anxiously to the European he let out a soft, deep chuckle as he dabbed his mouth with a napkin.

"Ah, it hasn't even been a full day and you have gained yourself your first rival, Young Midoriya. Ah, to be young," Yagi said in amusement. Then took another bite of pork cutlet before taking a spoonful of the savory fish broth. "Delicious. My complements once more to the chef."

"I don't want a rival!" Izuku wailed then squealed as the door shook with the force of something other than fists on the door.

"Answer it," Yagi ordered in an authoritative tone that broach no room for protest.

Izuku opened his mouth as if he was brave enough to stand against the tall, elegant man, but clamped his mouth close and reluctantly stood up. He let out a bone-weary sigh as he dragged himself the few feet towards the door and opened it just before a foot could connect with the door. He barely had time to react before he had an armful of a blonde teen boy the same age as him.

"You!" the blonde growled out indignantly. Garnet red eyes narrowed, cheeks flushed in anger and embarrassment of losing his balance and teeth bared in a snarl.

"Me?!" Midoriya squeaked out, wondering what fresh hell this was now.
