Fairy Tale (Chuunibyou!Izuku)

Basically, I just wanted to have an excuse to write Chuunibyou!Izuku at some point in my life. This is an experimental fic that I did on a whim so who knows if I pick this story up again at some point. (This is a one-shot btw.)

I wrote this in one sitting so pardon me for any spelling/grammatical errors and incoherent babbles.

Summary: As a child, Izuku had always been off in his own world. So when he gets a quirk fueled by his imagination, his personality takes a rather odd turn.

Izuku has been coming home late recently.

Normally, it wouldn't be too suspicious since most kids his age often got caught up playing with their friends outside. However, Izuku wasn't like them— he preferred to stay inside and read story books or watch hero videos all day. He'd rather sit at one spot for hours on end.

But nowadays, he looked completely exhausted; like he constantly ran a marathon every day. At times, he's covered in bruises and scrapes. She wasn't blind to his limps and minute flinches, either.

She even caught Izuku having long, one-sided conversations with himself. Izuku has always been a unusual child who spoke and acted differently from other kids, but he had never done anything like that before.

Inko thought that it might be his quirk— that her child may be seeing something that's not there, but the doctor said that it wasn't the case. Izuku may not have an extra joint, but her son's quirk is still dormant. "Perhaps it's just his imagination," the doctor said.

Yes, she was told it was normal for kids around Izuku's age to have imaginary friends, but she can't help but worry. Being extremely introverted at a young age wasn't healthy. I mean, the only friend he had that wasn't imaginary was Katsuki— and that was only because Katsuki is her friend's son!

It was why Inko resolved to get her son to talk. Did he prefer to be alone because kids picked on him at school? Why has he been returning home late? Was there anything she could help with?

As his mother, she wanted to know.

"You know you can tell me anything, right?" She said, gesturing at her son to sit beside her. "These couple of weeks, you've been coming home tired and injured. Are you being bullied? What's going on?"

He froze like a child caught pilfering from the cookie jar. He began to fidget and stammer, trying to explain his situation. "I-I-It's nothing like that, I just—"

"I know that kids have been picking on you for being quirkless, okay? You shouldn't have to put up with them, Izuku! Just because you don't have a quirk doesn't give them an excuse to—"

"M-Mom, you've got it all wrong," Izuku interrupted her rant. He then mumbled something under his breath.

Wait, what? Did she hear that right? "Can you repeat that?" When he opened his mouth to speak again, she noticed that his bottom lip was trembling. "Louder, this time. I'm not mad. Calm down."

Izuku sighed. "...I have a quirk."

"You do?" Why this was wonderful news! He's always aspired to be a hero like All Might, and now he finally awakened his ability. "That's great and all, but what's it got to do with your bruises? And why haven't you told me yet?"

Her son looked as if he was about to cry. Knowing him, he probably was at any moment now. "I wanted to surprise you on your birthday tomorrow! All the other kids have flashy ones! I've been training my quirk so you to be proud of me..."

Inko hugged her son. "Oh, honey, it doesn't matter to me what quirk you have. I'll always be proud of you." Thank god for that. The woman was glad she was mistaken. Heaven knows what she'd do if her son was truly ostracized by his peers.

She clasped his hands. "Then, can your dear old mother see her wonderful son's equally wonderful quirk?" Izuku nodded excitedly. His mom wanted to see his quirk, even if it's not as eye-catching as Kacchan!

He trotted a few feet away from her. Her son took a deep breath and closed his eyes. A light green aura enveloped his body as a glowing circle appeared in front of him. Wind gathered and circulated in one spot until she could make out a shadow. In a split second, he opened his eyes and spread out his arms. "Fairy Sylph, come on out!"

Much to Inko's wonder, an actual fairy emerged from the wind. She had light green eyes and matching hair. Her heart-shaped face was framed by two, feather-like bangs and elongated ears. The tiny creature's body was covered from neck to toe with feathers of varying shades of green; arranged in such a way that it looked like a dress. Finally, on her back were delicate butterfly wings that glittered with every movement.

She was ethereal; downright gorgeous.

Inko felt like a little girl all over again.

"You shouldn't be sad about your quirk. This is incredible! I've never heard of someone summoning a fairy befo— IZUKU!" Inko panicked. Her son was lying down on the floor, unmoving. She carried him in her arms and began fanning him with her other hand.

The freckled boy held out a shaky hand to her. His mouth trembled as he spoke to his mother, "Calling Sylph is really tiring, mom... it's why I've... been practicing. Didn't wanna... keep passing out every time..."

"Izuku, I know you're excited and all but please don't push yourself too hard. It's a great quirk, but I don't want your health to suffer because of it."

A few hours later, her son already recovered. It wasn't anything life-threatening, but his quirk was extremely taxing on his stamina. Ever since that day, she helped her son harness his quirk so he wouldn't be too exhausted every single time he uses his quirk. In turn, her son was able to summon without collapsing and often went home with a tiny spirit companion or two.

For quite some time, Inko believed that he can only summon small creatures like Sylph and the azure-colored animal that tagged along during their trips to the grocery.

Then one day...

"I'm home!"

She went to the doorway to greet Izuku. "Welcome ba—" Inko dropped her ladle in shock. Her eyes widened incredulously as she stared at the creature behind her son. She raised a quivering finger at it. "W-W-W-Wha...!"

The freckled boy was lying down on the doorway. Izuku beamed at her as he tiredly patted the enormous, reptilian snout beside him, which was blocking the entire entrance. Smoke steadily leaked from the sides of its mouth as it let out a deep, throaty growl. She heard faint screams from outside.

Inko almost had a heart attack.

"Izuku!"

There was a reason why Izuku was her favorite of them all.

Obaa-sama, as many in the family addressed her, was the stern and strict matriarch of the Midoriya family who ruled over them with an iron fist. She may not be able to burn everything down like her husband, but she was incredibly intimidating and a figure of authority in their bloodline.

Contrary to popular belief, it was she and not her husband, who held the power in the family. She was the one who entered public service and eventually, the military. She was the one who went to the frontlines against the vilest of villains, whilst her husband stayed home to protect their children. She was the one who fought against the oppression against the quirk users. She was the one who brought prestige and honor to their family.

Thus, her word is law.

Much to her dismay, none of her children became like her. No one entered public service— no heroes, no policemen, no soldiers, no anything. They all settled for mundane jobs and thankless careers. Not to mention that no one bothered to at least hone their abilities. The powerful quirks they were blessed with were utterly wasted on them.

To rub salt into the wound, none of her children were able to inherit her quirk. Instead, they took after her husband's stronger quirk, and her grandchildren and great-grandchildren were no different. They either inherited fire or from their other parents who had equally strong and impressive abilities. If she, with her unconventional quirk was able to make a difference and bring honor to their family, then surely, those with better quirks can do the same if not better, right?

Honestly, her descendants were hopeless.

That is, until Inko, the wife of her youngest grandson, brought Izuku.

The child wasn't anything impressive— scrawny, clumsy, and soft-spoken. He cried easily, bruised easily from tripping everywhere, and for some time, he had been declared quirkless. She thought that he would be another failure in a long line of failures.

But then, it all changed on Izuku's fifth birthday.

The once thought quirkless child actually had a quirk. And not just any old ability, it was hers; he inherited her quirk. She was happy. Finally, someone in the family took after her! Not to mention that he had a more powerful version of hers and was ambitious enough to want to be a hero. This was the perfect opportunity.

"You're special, Izuku. You're the next hope of this family," She spoke as she petted his head. "Remember, every one of us is counting on you to restore our reputation."

Obaa-sama began to treat Izuku differently from the others. It was obvious to them that she regarded him with favoritism and many of their relatives were jealous that he was the one getting attention from the bitter old hag; that he's the one most likely to become head of the family in the future.

From then on, Izuku was convinced that he's meant for something more.

Izuku hadn't let praise and special treatment get to his head like Kacchan, however, it did lead to him developing a rather... odd personality.

The Midoriya matriarch was too blinded by the prospect of reputation that she never noticed anything, but the rest of the Midoriya family saw and knew all too well what was happening to the kid. It didn't help that his quirk thrived from it, either.

Obaa-sama's influence was fueling Izuku's delusions.

Oh, boy.

All Might was no stranger to eccentricities.

In the hero community, you interact with people from all sorts of backgrounds— and this meant meeting the more... colorful of the bunch; himself included among them.

But never has he met anyone stranger than the young man before him.

"I have anxiously waited for this day; the day that Obaa-sama has foretold— the arrival of my destiny." The green-haired boy covered his left eye with a trembling hand. It was briefly reminiscent of another hero he saw posing on live television. "To think that it would be you of all people... that you and I meet must be a fate decided by the world itself."

The man had been chasing a slime villain earlier. He barely made it in time to rescue the kid from being suffocated and taken over by said criminal. When he woke the kid up, All Might was taken aback because the boy he saved spaced out only to instantly burst in joy. For a moment, the man swore he saw sparkles appearing in the background.

The boy then directed his gaze at him. He expected the boy to thank him or something—

"I-I summoned you, didn't I, Sir All Might?"

—not this.

"Summon? What do you mean?" He scratched his head in confusion.

Predictably, the child ignored his query and went off to a tangent.

"Of course, I would summon you. I'm the best in the world. Obaa-sama even said that my quirk is more advanced; that I could summon any being! Ah, but wait. I can only summon spirits, not living people." He paled fast. "Oh, no. This is bad. This is really, really bad. If I summoned him, does this mean that Sir All Might is... is..."

The man felt dread settle in his stomach. The boy looked like he was about to cry. He jumped in surprise when the boy yelled out of the blue. "NO, THIS CAN'T BE TRUE!"

(What kind of kid did he rescue?)

However, who could have imagined that this eccentric, crybaby young man reminded him of what it means to be a hero: that heroes risked their lives to fight villains and protect the citizens.

His fists still quaked at the reminder of his momentary weakness.

Due to his carelessness, the slime villain was able to break free from his temporary container and captured another child whilst he idled by because he had reached his limit. Meanwhile, the kid fearlessly dove into danger, claiming that his body moved on its own.

At that moment, he was more heroic than any of the heroes.

It wasn't as if he charged in recklessly, either. His movements in confronting the criminal were clearly given thought; he crouched down low so he wouldn't be too noticeable and hurled his bag towards the villain's eyes.

This kid had what it takes to be a true hero. The only problem was...

"What's your name?"

The kid extended his arm in a melodramatic fashion. "I am Midoriya Izuku! Thy calling is that of a summoner, whose life is guided by and dedicated to the Sacred Guardian Spirits!"

(He has to give props to the kid— he already has a hero's dramatic flair done perfectly.)

"Ah, I see. You have been rendered speechless by your sudden arrival in an unknown location. You see, in my darkest moments, I sought out the strongest spirit in the world to battle against the forces of evil. Hence, I was able to call upon you."

He shrugged his shoulders. "Alas, it is unfortunate that you have passed on to the next plane of existence. But fear not, for I will peer into the ultimate abyss with you!"

...Somehow, the kid thought he was already dead. All Might sighed in exasperation. I guess, seeing my true form just made it worse.

He didn't know if this kid would be a viable candidate to be the next successor of One For All, but he did know that Izuku was plenty heroic and his heart was in the right place. He just has a... peculiar speech pattern and mannerisms that can put people off.

For instance, he refers to himself as the prince of a fictional kingdom and views heroes as some sort of honorable warriors or chivalrous knights. Villains aren't merely villains to him; he calls them all sorts of titles: tyrants, overlords, evil witches; you name it.

(All Might has seen this kind of phenomenon before, back when he was a student. He had a classmate with a reptilian quirk who firmly believed that he had a mysterious dragon force sealed in his left arm. He often proclaimed that he was a Dragonborn warrior.

What did kids call it these days— chuunibou? Chuuniban?)

Surprisingly, when he offered to admit him to Yuuei as a recommended student, the kid refused out of some sense of honor and fair play. He wanted to get into the school the old-fashioned way: pass the entrance exam. Although, he's going to be a piece of work; the kid was clumsy and totally unathletic.

His quirk was something else, though. To have the power to summon creatures that mostly exist in fiction... he can see where his student's imagination was coming from.

When asked about how he awakened his ability, Izuku only answered, "I have stared into the darkness, and the darkness has stared back. In my journey of self-discovery, I was able to call upon the beings of the universe!" He then gestured to the fairy sitting on top of his head. "Sylph, the Noble Spirit of the Healing Wind, is merely the first of many to have deemed me worthy of their power!"

(This was Izuku-speak for, "I was just hanging out somewhere when I accidentally activated my quirk. I summoned a fairy. Isn't that cool?"

All Might didn't know whether to be dismayed or impressed with himself that he's gotten used to his student's speech pattern and quickly understood what he was trying to say.)

The next ten months wouldn't be boring at all, that's for sure.

Iida Tenya was a person of principle and discipline.

Above all else, he wanted to be like his older brother, the Turbo Hero, Ingenium. He had always admired Tensei not only for his exceptional physical capabilities, but also for being someone who genuinely desired to help others. He was a paragon of virtue who would stand for his ideals, no matter what.

And today was his first step towards becoming that kind of person.

Up to this point, he was slightly disappointed by his peers. Many of them were clearly in for the hero industry due to fame or fortune— he could already see it with their actions and behavior. They were taking it as a game, making bets over who got more points compared to the others.

However, the one who disappointed him the most was the curly-haired kid.

Not only was he disruptive with his constant mumbling, he treated the entire thing like an otaku circus act. He was wearing the most outlandish garb he'd ever seen: a sequined All Might-themed top hat with large protruding attachments mimicking the hero's hair and a black high-collared cape over his green tracksuit.

He looked absolutely ridiculous.

In addition to that, he had the audacity to prance around as if he owned the place and even attempted to sabotage their fellow examinees. Only the lowest of the low would consider such a thing. What a disgrace.

With such a horrendous first impression and after berating the kid himself, he didn't expect to work with him at all.

As the zero pointer destroyed the surrounding infrastructure and loomed over to attack them, everyone made a run for it. He was no different. He heard someone calling for attention, but paid no mind to it as he continued to flee the scene.

"Hey, I said. Sir Engine Legs!"

To his surprise, a green light blocked his way. Iida halted his dash, barely avoided hitting the small creature. His eyebrows furrowed in confusion as he stared at it. It was a fairy— a tiny fairy that was giving him a harsh glare.

He then noticed a light tug on his sleeve. He glanced to his side and felt irritation when he gazed at the strange curly-haired boy from before. The fairy was now sitting on top of the other's head. His lips pursed and curled into a slight sneer as he spoke to him with a harsh, stern voice, "What do you want? Don't tell me that you're planning on sabotaging even in this conditi—"

"You are mistaken! I am not so dishonorable as to put down our temporary comrades. I know you dislike me, but hear me out." The boy interrupted. He pointed in the direction of the gimmick robot. "I saw a young maiden trapped underneath the rubble over there." Iida's eyes widened. It was true, he saw a vague brown-colored shape in the distance. The robot was still some ways off, but if she doesn't get out of there in time, she could end up crushed.

"I'm not strong enough to lift the rubble or fast enough to get there in time, and to our misfortune, the mechanical golem is quickly approaching. I could destroy it, but it would be for naught since she might get caught in the crossfire." The kid scratched the back of his head. "If you get the lady out of there, I can take down the enemy for good."

Taking down the robot to show off? And what is with that speech pattern? "You do realize that it's not worth any points, right?"

The boy's face twisted into an angry expression. "It's not about the points. It's about helping her!"

As much as Iida abhorred the boy's previous conduct, this was no time to argue with him out of personal differences. The curly-haired kid was right; it is more important to help others than to squabble over petty things.

"All I have to do is run, right?" Iida flexed his legs. "You better not get any funny ideas."

He made an offended sound. "Of course not! Retrieve the maiden at all costs. I shall begin my incantation." Green aura covered his entire body as the atmosphere became heavier with each passing second. "O black omen hidden within the depths of the universe, spread your wings as you grace us with your divine presence..."

The curly-haired kid was downright bizarre. Iida blinked dumbfoundedly at the sight before shaking his head. No need to get distracted now. He activated his quirk and braced himself for the run. Any mistake could lead to the girl getting severely hurt.

"Wahh, it's coming!" The girl screamed in terror.

(In her panic, Uraraka Ochako had forgotten to make the rubble float off from her.)

In one massive leap, he zoomed across the street to her side. Iida focused intense energy on his leg and with all his might, he unleashed a kick to break away the large stone over her; creating a wide arc of sheer force that shattered it into tiny pieces. His actions caught the robot's attention and it went after them straightaway.

Just when they thought they still had time to get away, the gimmick machine's movement speed accelerated. It's crazy fast! Is Yuuei trying to get their applicants killed?! Iida thought.

Before the girl could even get a word in edgewise, Iida immediately carried her into his arms and ran for it. He furrowed his eyebrows when he saw the curly-haired kid still muttering. A bead of sweat trickle down his temple, and he felt his stomach dropped in fear. What is he doing? We're going to get crushed at this rate!

Iida had just run past him, when the curly-haired kid smirked. He raised his arms. "In the name of the summoner, I evoke your name," The sky darkened and the clouds swirled. An enormous circle filled with unintelligible scribbles and symbols appeared in the midst of it. "Come forth!"

What happened next shattered everything Iida knew about quirks. In his shock, his grip on the girl slackened and accidentally dropped her as both of their jaws dropped. Many other applicants in the distance also stopped running to gape at what happened.

"WHAT THE HECK IS THAT?!"

A large, black thing emerged from the heavens. It bellowed a mighty roar so powerful, it sent shockwaves on all sides. With every movement, the creature sent debris flying as it was too large for the street. Buildings collapsed and debris flew everywhere as it went on a rampage, tearing down everything in its path.

The zero pointer was no different. In one fell swoop of its tail, the robot went down. It then proceeded to breathe some sort of plasma from its mouth and destroyed the rest of the infrastructure and all other robots in the vicinity. After it wreaked havoc, it seemed to circle around to check if there was anything it missed. Somehow satisfied with its destruction, the creature disappeared in a burst of light.

(The curly-haired kid summoned a dragon. What the hell.)

Understandably, everyone was silent as Present Mic announced that the test was over. Nobody paid attention to the medics that came in, either.

Once upon a time, there was a kingdom established in the land of the rising sun.

The kingdom began as a small community founded by a farmer named Midoriya. He gathered all the other farmers that he knew to join him and help each other manage their farms. Under his rule, they flourished— what was a quaint little community now transformed into a bustling town. He then passed on the position to his only son, who also made their town thrive. The farmer's son would then pass it on to his own son, and so on and so forth.

As time passed, it continued to grow and grow and grow; from a community to a humble village to a boisterous city, and eventually, a kingdom was born. With the birth of a new kingdom was the establishment of a dynasty, and no one opposed the reign of the Midoriya family.

Like his predecessors, King Hisashi was just and kind. With his fair wife, Queen Inko, and his beloved son, Prince Izuku, the kingdom had many prosperous years during their reign— everyone was happy and content. It was why the people loved them dearly.

And it is also why they were utterly devastated when the king went missing.

One day, he just left and never came back. He abandoned his kingdom and his family to rot along with them. The queen and the prince grieved, and the people felt betrayed. The kingdom would have been in shambles without a leader. However, not all hope was lost. Because although the king has abdicated the throne, Queen Inko took a stand and became the new ruler. She picked up her husband's slack and lead the people as if the king never left.

Prince Izuku, who was expected to be lonely and bitter and loathing towards his father, was fairly unaffected by his absence. He moved on from his grief and remained a happy child. This was only thanks to his mother's guidance and the presence of his dearest friend, Kacchan.

Kacchan, as affectionaly named by Izuku, was the only son of Queen Inko's friend; the Duchess Bakugou Mitsuki. He was a precocious little thing who was both endearing and annoying. The duchess's young son was raised to be humble, but the commoners regarded him on a pedestal. He grew arrogant and developed a nasty case of inferiority superiority complex.

For all his arrogance, however, Kacchan was a figure of power and charisma— the picture of victory. It was why the other children followed his lead, and why Izuku admired him.

Both of them bonded over succeeding their parents and their dream of becoming a great knight like All Might. All Might was a legendary knight hailed for his numerous deeds. Despite his unknown identity, the people looked up to him. He was what every child aspired to be; a hero.

In a world of superhumans, Quirks were highly valued by society and knighthood was no different. Protecting the kingdom and the people would involve dangers of varying degrees. It was why the greater Quirk that a person possessed, the greater their chances of becoming a knight.

Izuku wanted to be a competent king who could not only rule, but also protect.

However, fate was unkind; he was rejected before he could even make something out of himself.

While children his age were discovering and developing their Quirks, Izuku has not shown any signs of having one. Out of worry for her child, Inko brought Izuku to the royal doctor.

"It's best you give up," The healer announced, pointing at a diagram of the bone structure of Izuku's foot. "The young prince is turning five soon and has yet to show any indication of his ability. He may not have an extra joint, but I concur that it's too late for him to develop anything at this point."

He was proclaimed Quirkless— a one-way ticket to becoming a social pariah. Many people viewed quirklessness as an undesirable mutation, and being the royal prince did not make him immune to their criticisms. Izuku, at the tender age of four, already knew that. But as long as he had his mother and Kacchan, he can take anything.

"You're a quirkless loser," Kacchan declared the next day. "Who'd wanna hang out with a weak Deku like you?"

He heard something shatter.

Maybe it was the glass he dropped. Maybe it was the bone in his arm after the bullies stomped on it.

Maybe it was his tender heart left broken in pieces due to Kacchan's heartless words.

Inko, witnessing his descent from a bright young boy to a melancholic child, knew she had to do something to cheer him up. The queen decided that if her child would not have any inherent ability, she would teach him magic. But she would not settle down with just any spellbook; she wanted only the best for her son, after all.

The queen gathered her most trusted warriors, saddled her loyal steed, and departed in search of a tome said to contain powerful spells (That would be 1500¥, ma'am," The clerk said.). She and her entourage was successful and thus, she returned from her journey giving the tome to Izuku.

"This is a tome filled to the brim with a wide array of spells. It takes a lot of responsibility to handle it," Inko spoke gently to her son as he hung on to her every word. "Perhaps you can't be a knight like All Might, but I know you can be something else just as great."

The young boy held onto the tome like a lifeline. He then hugged his mother tightly and thanked her profusely. "You're the best mom ever."

"I'm you're only mom," She joked.

Since then, Izuku spent his days reading the tome and memorizing every page to the last detail. He didn't want to waste the opportunity given to him by his mother. He quickly learns that it was not just a mere spellbook— it was also an autobiography detailing rituals involved in summoning spirits and monsters.

It was penned by a gifted sorcerer in the days of yore. They spoke of their travels through various places across the land. The boy was instantly fascinated by their tales. In fact, he had been so enraptured by them that he decided to try the casting spells on his own.

Though he may not have a talent for spellwork, Izuku discovered that he had a penchant for summoning. On his first try, he was able to call upon a tiny wind spirit called Sylph. He was spellbound by the mesmerizing beauty of the fairy that his mother caught him practicing magic without supervision. It was how she came to know his newfound skill.

His mother forbade him from summoning greater spirits for his body may not handle the strain. This doesn't deter him from trying time and time again. He didn't want to stay a powerless Deku any longer.

One tale in particular caught the prince's eye. The sorcerer claimed to have called upon the Dragon King, whom they tried to form a contract with. However, the dragon rejected them and sent them away with a large burst of its flames.

Izuku immediately knew that this was the summon meant for him.

Without telling anyone, he sets off to prepare the ritual to summon the Dragon King. Izuku went to the forest for his next deed. The young prince looked around to check if anyone followed him. Satisfied that he got away undetected, he then began the ritual.

"O ancient wyrm, ruler of the sky... hear my plea," He chanted while his body glowed with raw magic. There wasn't really any guarantee that it would work since the sorcerer noted there weren't any specific words to summon it, only that he had to mention its name; but this was the king of the dragons. If he wanted a pact, he had to treat a summoned being with respect.

"I, Midoriya Izuku, calls upon thee, Bahamut!"

A large magic circle appeared in the sky. The clouds darkened and strong bouts of wind enveloped the area. Izuku felt like he was going to be blown away. He dug his feet onto the soil, held onto a tree, and held his ground.

Suddenly, there was a crash above him, followed by another, and another— trees were knocked down with loud crashes. Branches, not just a few, but pretty much all of them fell as a pitch-black shape blocked his entire view above.

He then felt something poke his back. Izuku turned around, only to see enormous reptilian eyes looking back at him. The dragon's snout was forefront, with his equally large maw ablaze with flickers of fire.

"I didn't think it would actually work.”

According to Izuku, his ability is...

Quirk: Evocation of the Thousand Sacred Guardian Spirits (Official name is Imaginary Friend)

Description: The power to call upon the beings of the universe that exist beyond human comprehension (The power to create creatures and beings out of one’s imagination)

In other words, his ability is imaginary entity creation. It’s like Foster’s Home for Imaginary Friends; Izuku imagines a creature and it comes to life.

Details:

Belief-Dependent Physiology: Needs to believe they’re real so they can exist. (Good thing Izuku is a chuunibyou.)

Can create and delete imaginary entities at will. The stronger, the bigger, and more in amount he creates, the greater the energy spent.

Has a time limit on manifesting an entity. The time limit is inversely proportional to the power, size, and complexity of the imagined entity. His current time limit for Bahamut is 1 minute.

Can give limited independence to an entity. (The entity can’t decide for itself. Rather, it acts upon Izuku’s will. How it interprets his command is where the “independence” comes in, and it also depends on what personality Izuku imagined it to have.)

Since this is technically a mental power, if he overuses his quirk, Izuku will risk not just body, but also mental fatigue. He will also suffer from headaches, nausea, and in severe cases, a nosebleed.

If you haven’t noticed, Izuku doesn’t stick to one chant. This is because he technically doesn’t need it, but due to belief-dependent physiology, he has to do it because chanting enforces his belief that he’s genuine summoning something that exists.

How the heck did Izuku become a chuunibyou? And what did you mean by “he didn’t let it get to his head like Kacchan”? Chuunis are arrogant!

Izuku becomes a chuunibyou because he was already slightly delusional in the first place. The last part of the fic was from his POV. Izuku viewed the world like a fairy tale as a child, hence the title. And because he gets a quirk fueled by imagination, his delusions just get worse. Not to mention that his great-grandmother egged him on.

The definition of chuunibyou is “a person which manifests delusional behavior, particularly thinking that one has special powers that no other person has”. They don’t have to be arrogant or think they’re above everyone else; just that they have a special power. You could say that the arrogance is a by-product of the chuuni mentality. 

In this case, Izuku doesn’t get the arrogance.

Why did you even think of this in the first place?

Because I always thought Izuku would grow up different if he had a quirk in the first place, I wondered what would happen if he had an overreacting imagination stemming from his childhood days; and what happens if he gets a quirk that makes this problem worse. Thus, Chuunibyou Izuku was born.

I guess you can say that he is truly a madman in every sense of the word.

I’ll show myself out now.
