My Hero Academia

Devour the Greedy World

Chapter One

Hand of Fate

Izuku Midoriya gained his Quirk at the age of ten, but never knew what it did until he began his first year of Junior High. Doctors tried their best to discover its power, but since it wasn't something like a Mutation Quirk that changes physical attributes, they were left stumped, asking him to report anything out of the ordinary that happens to him.

The young boy had been excited, believing that he was Quirkless due to the late bloom of his power. What was it though, he wondered- Something was amazing as his idol, All Might? Perhaps something as flashy as the #2 Hero, Endeavor? After two years of striving and trying everything he could, Izuku felt more and more determined to find out what his Quirk could do. After all, how else could he attend the prestigious U.A High School and become as great as the #1 Hero?

By age 14, all Izuku knew was he was really, really hungry. This started to become an issue- a deep-rooted hunger that would slowly twist his mind and lead him to the incident that would change his life forever.

His days were numbered before it was time to apply to U.A. There wasn't much time for Izuku to pull himself together and prepare. But… What was his Quirk? How the hell could he find out?

It was the constant pressure from his classmates, all of whom had developed their Quirks well by now, that led him to the school's rooftop after class one day. In particular, a line from his childhood friend, though often quite the bully, Bakugo Katsuki.

"Maybe if you take a dive out that window, you'll sprout some wings or somethin', ya fuckin' nerd!"

Izuku smirked a bit as he looked over the edge, leaning onto the tall railing, his hair fluttering lightly in the breeze. Something inside of him was broiling, threatening to come to the surface, he could feel it.

This is it… This is how I get it to come out! He thought, tensing slightly as he hefted himself up and over the railing, standing at the edge. The wind began to pick up slightly, causing him to shift a bit as he held onto the metal behind him, looking down at the several story drop with a mix of thrill and dread. It has to happen now… It has to!

He nudged himself forward, but stopped, tensing up harder, a normal knee-jerk reaction that anyone would have facing a potential fatal fall. Izuku scowled at himself, trying again, and again, but never quite able to push off.

"Come on," he grumbled. "This is… The only way to know…!"

Some sort of unconscious thought brought itself to the surface. A last fleeting attempt by his mind to stop him. How many others have killed themselves this way, trying to find their Quirk? What if… What if it doesn't work? I-

Then, it was gone. As Izuku felt a pang of strange hunger that spread through his stomach and enveloped his whole body, he completely let go.

As his body started to fall forward, Izuku closed his eyes, trying to feel his entire body and find something that was different. He had to find something that would awaken within him, put to the test by the present danger he was facing.

Awaken… Come on!

Then, it happened.

"What the fuck are you doing, you little shit?!"

The deep, growling voice echoed around in Izuku's mind, making him gasp out at the loudness of it as it racked his brain. His hand suddenly shot out without him doing so, grabbing hold of the railing once more, surprising him. Izuku was dangling there, looking down in horror, blinking in surprise that his fall had been stopped.

"What…?" He looked up, expecting to see someone holding him there- But he was tightly gripping the railing, unable to do anything.

"Come on, get up already," came the voice again, equally as hostile but not quite as loud, making Izuku wince a bit. He tried to pull himself up, but his scrawny arms weren't exactly used to such force. The voice audibly sighed, and Izuku's arm suddenly managed a burst of strength to pull him up and over the railing hard, sending him landing hard onto the rooftop with a gasp. "Of course, I had to be inside the weakest guy around. Just my luck."

Izuku sat up, rubbing his back and looking around, making sure nobody was speaking to him. Then he reached up slowly and rubbed his forehead.

What's going on? Am I just… Hallucinating?

It was then that he noticed something on his palm. He lowered his hand and looked at it, unsure of what to make of what he was seeing.

Is that…?

The eyeball on his palm suddenly opened, and Izuku let out a scream of terror. He slammed his palm onto the ground, starting to scrape it along the ground.

"Ow ow OW-" The voice reacted to Izuku's sudden fearful attacks. "STOP IT!"

Izuku stopped, groaning at the loudness of the voice in his head, feeling like an intense headache. After a moment of silence, he slowly looked down at his shaky hand again, seeing that mysterious eyeball looking up at him with scorn. The iris of the mysterious eye was colored red, with a series of interwoven patterns of gold inside of it.

"Are you…" Izuku gulped. "The voice…?"

"Who the hell else would it be? It's about time you noticed me," the voice retorted with a scoff.

"Wait… You've always been there?"

"Of course I have! I've been inside you for years now, you've just been too worthless to let me out!"

This is… Not what I expected, Izuku thought. Am I just going crazy-

Suddenly, his hand with the eye flew up and smacked himself in the face. He gasped, surprised as he saw the eye move side to side, as if the voice was shaking its head.

"You're not the one going crazy here, I am," the voice told him. "After all, you've let me starve for literally years. YEARS!"

"Starve…" Izuku instinctively reached for his stomach with his other hand, feeling that strange pang of hunger once more. "So that was… Because of my Quirk? It's only been getting worse and worse, I was… scared."

The voice sighed. "Well, if you had satiated my requirements, it wouldn't have taken me four fucking years to come out."

"B-But, I eat three square meals a day," Izuku retorted. "How much am I supposed to-"

SMACK! His right hand slapped himself again. Izuku grabbed the hand, trying to hold it away, but somehow his right arm became much stronger when being controlled by his Quirk, easily breaking free and hitting him over the head again.

"Idiot! Obviously normal food isn't the answer," his Quirk berated him. "How have you not figured it out yet?"

Izuku groaned. "I don't know! How am I supposed to know!" He thought back to all the training he had done, physically and mentally, to prepare for a Quirk- Nothing had prepared him for something like this. A split personality perhaps? He couldn't be sure. Surely a Quirk with a mind of its own would be-

"Impossible? Hah," the voice broke into his train of thought. "If I didn't have a mind of my own, could I do this?"

Izuku braced himself to get smacked again, but nothing happened. He looked around, then down at the eye on his hand, which looked very pleased with itself.

"U-Um…?"

"Ah shit, I guess you couldn't see that… See, the way I see things, I have a physical form- So here I was doing multi-backflips in your mindscape, and you couldn't see it! Bleh!"

Izuku chuckled at this, making the voice eye him. "S-Sorry, it's just… Um… What should I call you?"

"Eh? You don't want to just call me something vague like 'The Voice' or somethin'?"

"It'd be inconvenient, yeah," Izuku said, trying to think. "I-If you're really… real… Then maybe you have an idea what you'd like to be called?"

The voice closed its eye, making a soft hum as if thinking. Izuku could feel something in the back of his head, and somehow knew that it was searching through his memories. On a whim, he closed his eyes, and could see hazy recollections of events from the past four years in his mind. As he watched, the memories finally stopped on one occasion, where Izuku had been testing to see if his Quirk was water-based, via dunking his head into a tub of water. It didn't take him long to realize that wasn't it, as he pulled his head out, gasping for air.

"This is…?"

The voice shushed Izuku, and the sound of the door opening could be heard. In the memory, Izuku turned to see to see his Mother standing there, peeking in at him worriedly.

"Izuku…?" She raised an eyebrow at him. "Are you okay?"

"Y-Yeah, I was just, um…"

His mother smiled and laughed softly. "No luck yet, huh? I believe you can do it! After all, you're not one to give up so easily- Just be careful, okay?"

"I will, Mom," Izuku had replied.

As his mother turned to leave, there was a word printed on the back of the shirt she was wearing, alongside a very happy looking hamburger mascot. The memory seemed to focus on that.

"That's it! Yeah! That'll be sweet!"

The memory faded, and Izuku opened his eyes, blinking. He looked down at the eye on his hand, which moved in a way to appear as though it was nodding, satisfied.

"I remember thinking at that time that it would be a cool name, but it was too bad you suck and left me in darkness for so long!"

"That's, uh… Very specific," Izuku said, but he smiled down at his hand. "Okay then… I'll call you that-"

"Musabori." ((Note: Musabori = "Devour" in English.))

Inko Midoriya had never seen her son so excited as when he returned home that day. He waved to her and headed towards his room, telling her that he's on track to finding out what his Quirk is all about. She nearly dropped what she was doing, incredibly happy to hear that.

In reality, however, Izuku was still very perplexed. As he sat down at his desk, he turned the lamp on and placed his hand out onto the table. It was still a bit chilling to see the eye that opened up there. Like a normal eye, it protruded slightly, but it was almost like he couldn't feel it, even when his hand was closed or grasping something.

"S-So, Musabori… What am I supposed to do?"

Musabori rolled his eye and sighed. "Since you're an idiot, as established, I'll make this real clear for you- My power is amazing. You can practically become a God of this world, if you do what I say, capiche?"

Izuku gulped. Hearing about becoming a 'God' would normally sound absurd, but at this point, they were way past the point of absurdity.

"Okay okay, I get it. Just tell me what I need to do to, um… Help your hunger?"

"That's right, my hunger… Well, it's quite complicated, so listen up closely," Musabori began, before clearing his throat for some reason. "You see that pen on the desk? Pick it up with your other hand." Izuku did so, taking the pen. "Now hold me over it, and say 'devour', alright?"

Izuku hesitantly brought his right hand over the pen. "D-Devour…?"

Musabori sighed. "The word doesn't necessarily matter, but it sounds cool, don't it? Hahaha- Alright alright, now watch this."

There was a flash of light, and a dark, swirling mass slowly moved out from the palm of Izuku's hand. He froze up, watching the sight with both fascination and horror, as the darkness slowly enveloped the pen after a few seconds. Then, in the blink of an eye, the pen suddenly collapsed into a singularity that was as small as a thumbtack, before it got sucked back up into his hand. The sensation was odd, and Izuku turned his hand over, watching as the small, dark blob got absorbed into the eye.

"Not really the tastiest thing possible, but hey, at least it's better than an empty stomach," Musabori spoke wryly.

"W-What was that? Where did it go?"

"Hmm, how to explain, how to explain… I'm not exactly sure myself, all I know is that the more you let me eat, the better I feel," Musabori said. Izuku got the sensation that he was shrugging, which was odd. "Since I've had a few years to prepare, I figured this was the best way to present the next part to ya."

Izuku's eyes widened as he saw something suddenly get inscribed onto his palm above Musabori's eye. It looked like it was being carved in, but he didn't feel any pain, just that same strange sensation as when he had used his Quirk's ability.

"This is…?"

It read as three lines:

5 Points - Summon Item

10 Points - Create Item

20 Points - Reconstruct Item

"Like a game?" Izuku blinked, thinking about all the possibilities of what it might mean.

"That's about the gist of it! That pen you had me eat was only worth five points- Probably because it was cheap and worthless, sorta like you- My bad my bad, look, just try out that first thing!"

"Summon… Item?" Izuku watched as the swirling mass appeared once more, creating the pen from seemingly out of nothing above his palm, before it clattered to the desk. Izuku poked it for a moment, but nothing seemed out of the ordinary with it. "S-So this is the original?"

Musabori chuckled confidently. "That's right! Pretty neat, aint it? Imagine all the cool stuff you could do!"

This was like nothing Izuku had ever heard of. Not only was his Quirk capable of literally naming itself, but it was able to manipulate part of his body without his consent, and had a strange power that the Quirk itself tailor-made for him to comprehend. He gulped, a wide grin appearing on his face, which drew a confused look from Musabori.

"This is… This is…"

Musabori squinted at Izuku, and he could feel that his Quirk was also grinning.

"So cool!"

The U.A Entrance Exams were less than six months away. It was now or never for Izuku to train up his newfound Quirk, though he knew there was only one way he could truly do so without anything getting in his way:

He had to keep it a secret.

Besides telling his Mother that he was learning about his Quirk, nobody else could know. He discovered that Musabori could hide himself, which made it a bit easier than explaining why there was a literal eyeball on his hand.

Every day after school, Izuku learned. With Musabori's guidance, he was able to know that his Quirk would get stronger as he devoured more and more items, his "point" total rising. His capacity at first was only twenty points, which Musabori scolded him for, saying it was because he was on an empty stomach for so long. Soon enough however, Izuku was able to raise this total through trial and error.

"Devour!" The book that Izuku had been holding his hand over was enveloped in darkness, and absorbed within a couple of seconds. He smiled down at his hand. "Wow, it's getting faster, too!"

"Damn right! And check it out- You got a new skill!"

"Skill…? Y-You really made it like a game, huh." Izuku looked at what was being inscribed onto his hand. He blinked at it. "W-What? How is that…"

"Just try it! Point me at somethin'."

It cost a hundred points, which was his maximum point total at the moment. The book, which had been a whopping eighty points for some reason, was the only thing Izuku had devoured right now besides a twenty-point piece of gum he had attempted it on moments ago.

If I use these points… Do all the items I have devoured go away forever? Izuku thought.

Before Musabori could chime in and tell him, or rather yell at him, Izuku held his right hand out towards a nearby tree on the hillside, and spoke: "Depravation!"

Izuku felt his whole body exert some energy, nearly stumbling as what appeared to be a blast of dark mist exploded from his hand. It slammed into the tree before dispersing into nothing. After a moment, Izuku assumed nothing would happen- But sure enough, the spot that had hit suddenly began to lose its bark, and it spread a little ways up and down the trunk, the bark peeling and falling to reveal rotten wood underneath.

"W-Wow…" Izuku shivered, feeling chills go up his spine. "This is, um…"

"You're thinking it's kinda evil, huh? Well, it's all about how ya use the power, right?"

Izuku was weirded out by something. As Musabori spoke, his eyes widened as he realized what it was- No longer was the voice speaking inside of his head. He slowly turned his hand over, looking down at his palm.

There, just below the ever-present eye of Musabori, was a mouth. It grinned at him with sharp, pointed teeth.

"What's up? Oh… Yeah yeah, I'll be able to develop more as ya' increase your point total," Musabori said nonchalantly. "What? Don't look at me like that!"

"W-Will you… Fully form, eventually?" That thought gave Izuku the creeps, imagining an entire person forming from him, or perhaps he'd even look like a conjoined twin at one point.

"Hmm.. I'm not exactly sure, to be frank. I don't think so, though," Musabori insisted. "Like I said, I can feel my entire body, and it ain't yours. It's like I'm… Using you as a medium to interact with the world."

"S-So I'm possessed?!"

"Not like that! Well… Maybe, actually-"

Izuku let out a fearful gasp, and Musabori laughed. It was strange seeing how much personality his Quirk could manage with just a single eye and a small mouth.

I really… really need to tell someone about this, Izuku thought, deciding then and there that, perhaps, keeping this a secret wasn't the greatest idea.

After a long day of training his Quirk, Izuku had managed to get his maximum points to 200. As he had feared, any items he had absorbed were lost when his point total had hit 0- He couldn't resummon them when he got enough points. He could, however, use "Create Item" to make a copy of any item he's ever devoured. Apparently though, the copies of items would get worse overtime if the original was no longer stored, so it wasn't much of an option unless he was desperate.

That night, Izuku returned home a bit late, sitting at dinner with his Mom. He felt exhausted, realizing very quickly that using his Quirk seemed to burn through his stamina pretty quickly. He also had noticed that, as his own stamina grew weaker, Musabori seemed to disappear and get quieter.

We must be really connected then, He had decided. If I'm weak, he's weak. But it doesn't really work the other way around… Hmm…

"Izuku?"

He looked up from his thoughts, seeing his Mother's worried look. He had been poking his food with his fork for a while, and finally set it down.

"M-Mom, I have to tell you something," he began, gulping. "I… Um… It's about my Quirk!"

Inko smiled, putting down her utensils and leaning in with a bit of excitement. "Of course Izuku! You can tell me anything!"

Izuku thought about his strange Quirk, and all of the fears he had about it. The fact that Musabori could act on his own was a scary thought, but at least knowing he was bound by Izuku's own strength was a slight comfort. Still, how could he tell anyone everything without making it sound like he needed to be put in a straight-jacket?

"It's really cool," Izuku began, smiling reassuringly to her. "It's hard to explain, but I'll try one day- Just know that it's really coming along!"

"Wow! That's amazing to hear," she said with a nod. "Are you having any issues? Quirks can be hard on kids."

He shook his head. "N-Nothing that I can't handle. I'm just… I'm so happy that I finally have a shot at being a Hero… Like All Might!"

Inko thought about her young son being told he had no Quirk, and how much that had devastated him. Later, when a routine doctor's visit had revealed he held the Quirk genes after all, it had changed Izuku back into his wonderful, excitable self once more, and that had made her the happiest Mother alive.

Standing up, she walked around the table and hugged Izuku, who looked up at her, a bit confused.

"Izuku… I know you'll do great," she spoke, tearing up a bit. "I love you so much!"

"M-Mom…" Izuku smiled, leaning into his Mother a bit. He was happy to have such a reassuring parent there for him. She had always been supportive of his dreams and goals, even when all hope seemed lost for him…

Wait, something was wrong. Izuku's eyes had trailed down at the table, and he noticed something was missing. The… fork? No, he had set it down, right? For some reason, it was like he was having trouble remembering it touching the table. But Musabori was asleep-

He felt his right hand start to move, his arm slowly going around his Mother, embracing her. Izuku barely noticed that he wasn't the one doing it, looking and watching as his hand peaked up from over her shoulder, the eye of Musabori gazing at him. His mouth opened into a wide, toothy grin.

"Thanks for the meal~"

Izuku couldn't stop it, as his hand moved against his Mother's neck, Musabori's teeth sinking into her skin and tearing at her flesh. Blood spurted out, and Izuku was left watching, too shocked to do anything in the moment.

"Izu...ku…." His Mother's eyes never left him, but her arms went limp around him, her body swaying. As she fell over, blood starting to pool from the large gash on her neck, Izuku finally felt himself moving.

"Mom! Mom!" He knelt beside her, shaking her a bit and moving her head to see the wound, his hands covered in blood by now. He didn't know what to do, trying to think of any first aid he knew. Grabbing a nearby kitchen towel, he pressed it firmly against her wound, before looking around frantically for the nearest cell phone.

Then he heard it. A soft slurping noise. Shakily, Izuku raised his right hand, watching as a tongue was emerging from Musabori's mouth, licking at the blood that was on his hand. After a moment, the eye looked at him, as if only noticing him watching for the first time.

"What? It's rude to stare at someone who's eating."

Izuku could only stare in disbelief. Musabori gave him a toothy grin.

"Hey, this is what you wanted, ain't it? A Quirk all your own? Well, here I am, baby! In the flesh!"

"We're gonna have a fun time together!"
