"You dare call yourself a Midoriya!"

"I'm sorry dad-"

"You should know by now I don't consider you my son!"

That was a daily conversation, or well if you want to call it that, of his dad and Izuku. Izuku thinks back to those days because as of now and forever his parents are dead with the blood on his hands. His dad was a hero that was obsessed with power and his mother was obsessed with how good she looked in front of the camera. They both did whatever it took to not hurt their image on social media and the pro hero scene.

Izuku had 3 siblings each who had a quirk similar to their parents; the only girl took after her mother and the second oldest took after his dad. While the oldest was the "best" of both worlds. Izuku always looked up to his parents and his siblings but their attitude towards him changed when he was revealed to be quirkless. That was when he was abused mentally and physically every day, and at school, it didn't stop either. At around the age of six was when he started focusing on his studies to at least try to impress his parents. Izuku's mental state was worse than someone in an insane asylum and the fact that he was six years old wasn't helping him. He was very frustrated, a little kid could only deal with so much until they burst, which was what happened. He was able to deal with the abuse for merely three years. That was when he awakened and unlocked his true quirk...

The day was the same as a usual wake-up, change, eat the leftovers, go to school, and go home. But the abuse was more physical than normal. His siblings were throwing harsh words at him while his dad was beating him senselessly. That was when he snapped, his vision was blurry and he had a slight headache, but all he could remember from the incident was the look on his parent's faces before he killed them, the faces of his siblings after killing their parents, and the pleasure he felt after doing so.

He ran away and lived on the streets for a while since no one reached out to him. People looked down on him as they walked past him on the street, but all he could do was just sit there and hope that one person had a kind enough heart to accept him.

"Hello, there little one."

Deku hears these words and looks up at a man. He was tall, very tall, maybe that was his quirk? That is what Deku was currently thinking about.

"What is your name?" Asked the strange, tall man.

"My name is Izuku...Izuku Midoriya."

"Well then Midoriya, why are you out here?"

"My parents...no my family are nothing but bastards. What I did to my parents was justified, and I should've done the same to my siblings." Said Izuku Midoriya

"What did you do to them?" Asked the tall man

"I killed them..."

An awkward silence fell between them, for about a minute straight not a single word was said. When Deku looked up he saw the man grinning and chuckling to himself.

"Listen Midoriya, do you want to show your parents that are watching from hell just how wrong they were about you? Show them that they in fact were the ones who should've been talked down by you?" Asked the tall man with that grin still on his face.

"Y...Yes of course! It would be an honor!" Said Deku

"Well then follow me." Said the tall man.

"By the way s...sir what's your name?" Deku asked while he caught up with the man.

"You can call me All For One."

Deku followed the man and it would soon turn to be the best fucking desicion he has ever made.

"The boy sleeps…" said the doctor also known as Shiga Maruta

"So you mean to tell me that you can't take this boy's quirk?"

"Yes that seems to be the case, I tried it a few times though the boy screamed in pain." replied AFO

Maruta asked what to do with the boy and to his shock AFO decided to keep him. Well

AFO was...intrigued? The two boy's he picked up off the street turned out to be very interesting indeed. He could see it already, he and his army of super soldiers and to his side are those boys, one whose quirk can wipe out nations within seconds, while the other had the potential to rival him in combat. He could picture it clear as day as if it was almost guaranteed to happen if he took in this child. What AFO wanted wasn't the power this boy had, but the things this boy could achieve.

Izuku wakes up from...a couch? Confused he gets up and sees the chambers containing the weird creatures. he was about to tap on one but-

"HEY THERE YOU CHILD! STOP WHAT YOU ARE DOING!"

Deku jumps at the sudden shout of the old man. Izuku sees that the man is wearing doctor-like attire, lab coat and such, but his face reeks of nothing but evil. Izuku bows his head and apologizes to the man not really knowing what is happening.

The man tossed some clothes at Izuku which shocked Izuku a little but then he picked up his clothes and changed into his shirt and shorts. He thanked him and got into his new attire. Nothing fancy, just a plain black and gray combo. 'Very boring' thought Izuku but he kept that to himself.

"You may call me Maruta, and AFO would like to speak with you."

Before Izuku could ask, Maruta points to a room that said 'BAR' so he gave a quick nod and opened the door to the other room.

"There he is! So you finally woke from your nap. Allow me to introduce you to your new ally and brother. Tomura Shigaraki." said AFO

What Izuku saw was a boy with white hair and red eyes, well he thinks that was what he saw. He couldn't really tell with the whole hands thing. He was about introduce himself but-

"Don't care…"

Izuku already didn't like this guy, he knew that this Tomura brat wasn't going to be a friendly person but damn did it really piss him off. Of course Izuku being the nice kid he is, he tried again but was also cut off again. AFO told Tomura to get along with Izuku since they are going to be allies whether he likes it or not.

"Why should I learn the names of those inferior to me?" questioned Tomura.

This sounded like a genuine question which made Izuku even more pissed and made him think only one thing 'I'm going to punch him'. Of course he didn't actually punch him since he wanted to make a good first impression.

"Well besides him you have another ally, meet kurogiri."

"Hello there young master I will be in your hands" said Kurogiri

"U-Uh yeah likewise." replied Izuku

'Now this guy seems more presentable' thought Izuku, comparing him to the white haired brat earlier. He would use a few others to describe him right now but that isn't what's important.

"Think of Kurogiri as a personal butler and trainer, also would you mind explaining what your quirk is Midoriya?"

"I-I'm not sure…"

"Get a load of this guy." said Tomura

'you're dead meat when AFO leaves' thought Izuku trying desperately to keep told Izuku to let him know if he ever finds out. AFO bid farewell and left the room leaving only Izuku, Kurogiri, and Tomura there in the bar. Izuku decided to walk around the room, and noticed that there were more doors leading to strange places. He found his way back and asked Kurogiri a question.

"Could you help me understand my quirk?"

"Why of course young master."

About a month of training passes and nothing occurs. No matter how hard Izuku trained he couldn't use his quirk, but nonetheless Kurogiri never gave up on him.

Izuku lays on the couch and wanders off into dreamland hoping that maybe some sleep will help him get some insight into his quirk.

CRACK!

He opens his eyes thinking he was still in the bar but now what he saw was an empty void all around him.

"You there!"

He hears a voice behind him and turns around but sees nothing and no matter where he looks he saw no one. Just an empty void.

"So...You were the one to inherit my power yet you seem too...pure for this kind of power."

"Who-Who are you!" questioned Izuku trying to make sense of this nightmare.

"Who am I? WHO AM I? I am known across your world and many different dimensions yet you have the audacity to ask who I am. You absolute imbecile!"

After relaxing himself Izuku says "Well I can't know who you are if I don't see you?"

"Well...I guess you do have a point." the voice says in a somewhat flustered tone.

Then a figure appeared in front of Izuku, one that looked exactly like him except he had white hair, red eyes, and a cloak. It reminded him of Tomura 'damn it! I didn't want to remember that brat!' thought Izuku but his thoughts were interrupted when the look alike talked.

"Do you know who I am now?"

"Are you some kind of idiot? You look exactly like me, so unless you are my long lost twin brother how could I know who you are?" said Izuku.

"AHH! YOU KNOW WHAT FUCK IT AND FUCK YOU! I QUIT, I WILL TELL YOU WHO I AM!" shouted the look alike.

"WELL GO AHEAD THEN I'M LISTENING YOU BIT-" Izuku was cut off.

"My name is Grim or The Grim Reaper...nice to meet ya."

Izuku stopped and was in shock then after realizing what he said he had thoughts flooding into his mind 'OMG I called the Grim Reaper an idiot! He is going to kill me and take my soul!' stuff along those lines.

"Anyway it seems you unlocked my powers...:" spoke Grim.

"WHAAAATTTT!"

"Anyway after you used my powers for the first time it is my duty to re-unlock them for you? Or I guess restructure the system that lets you use my powers. Well anyway that doesn't matter all you need to know is that my powers are like a videogame level-up system and you won't see me as often maybe a few times a year. Anyway, see you in most likely a few months." Grim said quickly.

"Huh? Wait! H-Hey! I have so many questions!" Izuku desperately shouted.

"Well sorry kid I don't have the time to answer them so the system will for you. Oh and by the way this is going to hurt a lot, like really painful stuff."

"Wait, what was that last part?" Izuku said nervously.

"Well good luck on your journey kid!" said Grim with a smile on his face.

"AHHHHHHHHHHHHH!"

Izuku jolted up out the couch a little freaked out but he still remembered that dream. Wait, was it a dream?

{Welcome player! you now have the chance to become the Grim Reaper!}

A robotic yet feminine voice spoke, when Izuku looked around it seemed no one heard it.

{To open your status window, think of the word status.}

'status' thought Izuku still a little doubtful about the whole situation but hoped it was true. Then a window popped up in front of him and he read the following.

{

LV 1 Izuku Midoriya

Speed: 7

Strength: 5

Stamina: 6

Mana: 10

Intelligence: 15

Agility: 5

Race: Human

Points: 0

}

Izuku sighed he didn't think he was so weak, of course he knew he wasn't strong or powerful but come on he thought he was at least not weak. But he had an excuse: he was still a child.

{To see the shop, think 'shop' to see the skill tree, think 'skills'} Izuku immediately knew what he was going to open. 'skills' thought Izuku and a big tree appeared. It branched off into many directions in which he could barely keep up with.

{The ones that are lit up are the ones you have unlocked and can use, you can also click on the skill to see how it works and its level. You can also purchase these skills from the shop but only if you have enough points to do so.}

Izuku took this all in and took a look at the skills he had

{Dark Energy: This skill gathers sad and negative emotions and turns into dark energy which can be solidified and liquified. It can also be stored for later use.}

{Grimm: A Servant of Grim appears over you and assists you by increasing speed, strength, stamina, agility, mana, and intelligence by 300%.}

{Reaper's Best Friend: This skill summons a scythe that can better channel dark energy and collect it. Helps you level up faster when used to kill.}

{Observe: Lets you see the strength of your target as well as being able to see a great distance.}

{Dungeon Create: Allows you to create a Dungeon to fight in but what rank the Dungeon is determines how long it takes to create it.}

'Very interesting set of skills, but I wonder if I can see what the non lit ones are' Izuku tried to tap on the unlit ones but nothing happened. 'Of course' Izuku thought to himself. He should have known that Grim wouldn't be that forgiving.

After a quick thought process he decided to use the skill {Dungeon Create} then a window popped up showing him the different ranks he could pick. The Dungeon created was random but the rank of said Dungeon could be picked. The ranks from lowest to highest are F, E, D, C, B, A, S. He chose an F rank which would take 1 min to make. He of course wouldn't mind that time since it was relatively quick.

When the dungeon was finished he received a box with the letter 'F' in bold all around it. It was like dice but instead of dots it was just F's. So he stared at it for a few more seconds before realizing that he had no idea how to use it.

{To open the dungeon all you have to do is say 'open'}

"Open."

After Izuku said those words, the box flashed a bright light in which Izuku closed his eyes. He heard noises and opened them. He saw a ruined city which looked to be abandoned and was taken over by the plants and trees. Izuku realized that this place wasn't an actual landmark, if it was it probably isn't well known.

{Defeat the boss to leave the dungeon, if you wish to know more think 'specs'}

Izuku did just that, which resulted in a window popping up.

{Defeat the Zombie King to leave, the sooner you clear the dungeon the better the rewards.}

"I guess I will have to risk my life to get some good rewards then." said Izuku

He saw a small horde of zombies approaching him as if they could sense him. He used his skill {Reaper's Best Friend} which appeared in his hand but turned out to be way bigger than him. It somehow shrunk to match his size but he could tell that it became weaker. 'Maybe it gets stronger when I get stronger? Like a sort of ego weapon?' thought Izuku but he had no more time to think of such things right now as the zombies got closer.

He ran away and turned the corner of a building the zombies followed but one of them was killed with a surprise attack, since he is currently weaker than even most kids his age he can't face them head on. He heard another sound.

{Level Up!}

{Level Up!}

'If all it takes to level up twice is to kill one zombie then I must really be weak.' thought Izuku while running from the remaining three zombies. He simply repeated this process three more times to kill the zombies since the zombies themselves were pretty dumb.

Time passes and Izuku sets up a camp of sorts in a tall building. Thankfully, he doesn't feel hunger in these dungeons but he does feel fatigue.

"Well at least I don't have to worry about food." said Izuku.

He opened his status window once more to see his progress.

{

LV 13 Izuku Midoriya

Speed: 13

Strength: 11

Stamina: 12

Mana: 23

Intelligence: 29

Agility: 13

Race: Human

Points: 278

}

"What are the points for?"

"Oh right, shop." said Izuku

In front of him opened a window which looked like an online shopping store. Something like Amazon, but it had a sort feature which showed the different types of items available.

"Skills, Weapons, loot boxes, armor…" Izuku kept looking at the sorts of things he could buy, but soon realized that he couldn't afford most of them.

"Well having 278 points doesn't mean much huh?" said Izuku, realizing that he couldn't buy anything overpowered just yet.

Izuku decided to look at the skills section to see what he could get his hands on for only 278 points.

"What's this?"

{[Cost:250p]Avatar: Gives the player the ability to manipulate the four basic elements: Earth, Fire, Water, Air. The higher the level the better the control.}

"I am 100% getting this!"

{Confirm purchase of the skill [Avatar]? There are no refunds.}

"Yes!"

The next day Izuku spent countless hours trying to understand how the skill worked. He figured out that the skill Avatar actually gave him four skills.

{Firebending: Gives the player basic manipulation of Fire.}

{Waterbending: Gives the player basic manipulation of Water.}

{Earthbending: Gives the player basic manipulation of Earth.}

{Airbending: Gives the player basic manipulation of Air.}

"skills."

{Dark Energy[LV 1]}

{Grimm[LV 1]}

{Reaper's Best Friend[LV MAX]}

{Observe[LV 1]}

{Dungeon Create[LV MAX]}

{Firebending[LV 1]}

{Waterbending[LV 2]}

{Earthbending[LV 2]}

{Airbending[LV 3]}

He felt better at fire and air bending but couldn't really find good places to use fire bending, since the smell of smoke could attract zombies. Air was technically everywhere so he could practice it whenever he felt like it.

Izuku's goal as of now is to find the Zombie King since he is now level 19. He might fight it if it's weaker than he thinks it is. So far it's been at least three days since entering the F rank dungeon. Izuku saw patterns with the zombies, they were more active at day than at night but were also stronger at night. So on the night of the third day he went out to go find the Zombie King. He acquired the skill {Stealth} and {Shadow Step} while trying to get past the zombies without being noticed.

His goal was to find the Zombie King before the end of the third day, so on the dawn of the fourth he could go for the attack. But of course he was unlucky and couldn't spot it. The night arrived and it was back to searching. He did use the daytime to kill a few zombies and acquire two basic but useful skills.

{Enhanced Hearing: Grants the player enhanced hearing capabilities.}

{Enhanced Sight: Grants the player the ability to see from further away.}

He hears a roar and immediately looks for the source. He sees a humanoid figure twice his size appear in front of him.

'It's fast!' thought Izuku as he barely managed to dodge its strike.

{Observe}

{

LV 27 Zombie King Baru

Speed: 53[+41]

Strength: 87[+35]

Stamina: 71[+32]

Mana: 50[+20]

Intelligence: 49[+18]

Agility: 51[+26]

Race: Human Giant[deceased]

}

'I can't beat that!' thought Izuku.

'I'll have to retreat and come back at sunrise then at least I will have a fighting-'

Baru swung his arms and hit Izuku, sending him flying into an open field.

"Damn it! Just my luck."

{Reaper's Best Friend} Izuku called out the scythe that has now adjusted to his size. He did use it a little these past few days in order to gain a better understanding of how to properly wield it. But of course it wasn't like he had mastered it yet, something like that would take years of hard work.

"If only it was a simple weapon like a sword or maybe daggers…" said Izuku wishing he had gained the favor of a swordmaster.

Izuku got up and tried to outrun Baru once more knowing it most likely wouldn't be possible so he used it as bait. Baru tried to squash him like a bug, but before Baru could connect the hit his hands were hit by spikes. Caused by Izuku's earth bending which moved Baru's hand off course.

Izuku uses earth bending to launch himself into the face of Baru and uses firebending to blind it.

"Take this!" shouted Izuku

Izuku uses firebending to blind the beast but his attack is stopped. Baru's speed was the lowest of its stats but thanks to the moonlit buff it's speed was higher than Izuku's.

Baru smacks Izuku again like a person would a fly.

"Dammit it doesn't even see me as an enemy!" said Izuku, tearing up.

{Grimm}

{Due to it being only level one the maximum amount allowed is 100}

"Huh? I didn't activate any skills?" said a confused Izuku.

"What does this do anyway?"

{Grimm: A Servant of Grim assists you by increasing speed, strength, stamina, agility, mana, and intelligence by 300%.}

"Wait what! Let me check my stats!"

{

LV 19 Izuku Midoriya

Speed: 26[+78]

Strength: 24[+72]

Stamina: 25[+75]

Mana: 37[+100]

Intelligence: 40[+100]

Agility: 25[+75]

Race: Human

Points: 2546

}

Izuku stands up and sees Baru approaching him.

"Alright now it's time to get serious!"

Izuku uses his skill {Shadow Step} to get closer.

{Shadow Step: Teleports the user a few meters ahead of where they were originally at.}

Izuku uses this to teleport behind Baru and he uses the scythe to slash at the back of its neck hoping to decapitate it. But the cut doesn't run deep as Izuku thought since his strength is still inferior to Baru's. So he backs off and thinks of a better plan that could potentially finish the job. Due to the increase in intelligence he gained better mana control, which means he can better control the elements. He quickly buys a cheap knife from the shop and charges at the beast.

Izuku stabs Baru in the stomach with all his strength which might seem like a bad and stupid move. But quickly he uses air bending to create a sphere that's radius starts from the midpoint of the blade and extends a little beyond the tip of the blade. Only the hilt sticks out as the air bubble causes the insides of the beast to open up. Izuku then starts pouring in fire to increase the heat. When the blade starts to melt is when the time is right. If he messes up he could end up killing himself along with Baru.

'Compress, compress, compress…now!'

A huge explosion causes Baru to explode and leaves its remains flying everywhere. Its head was gone from its body along with the chest area.

"I feel like throwing up…" said Izuku with a rather disgusted look on his face.

{Level Up!}

{Level Up!}

{Level Up!}

{Level Up!}

{You obtained the title 'Slayer of Zombies'}

{Due to taking 3d:15h:34m to complete the dungeon, your rewards will be adjusted.}

{You obtained a C-rank loot box!}

{You obtained a F-Rank loot box!}

{You obtained a F-Rank loot box!}

{You obtained a D-Rank loot box!}

"Okay I will open them from best tier to worst tier!" said Izuku

{

C-Rank: Assassin's Hood

Description: A black hood with a cloak that covers the body, best suited for stealth.

[+20 Speed]

2 Piece Bonus[+20 Stealth]

Full Set Bonus[Shadow Walker]

}

{

D-Rank: Assassin's Boots

Description: Black boots that are made of a soft material for quieter footsteps, best suited for stealth.

Bonus[+10 Speed]

2 Piece Bonus[+10 Stealth]

Full Set Bonus[Shadow Walker]

}

"Unfortunately the other F-Rank drops were just shitty weapons like the knife I used. How do I equip these anyway? Oh…inventory."

"After a few minutes of changing I feel right at home in these clothes!"

{Grimm's effect has ended.}

"Oh so it's only temporary that's coo-"

{You will now face the backlash.}

"Wha-"

Izuku couldn't tell what exactly happened but all he knew was that his vision was filled with red. The pain he felt was something he never wanted to feel again. 'Would it get worse if it leveled it up? Maybe I shouldn't. But it's such a good skill!' Thoughts like these were running through his head as he waited to no longer feel numb from the pain. Due to this he also got another skill.

{Pain Resistance}

THE END

I just wanted to warn you that the chapters probably won't be as long as this one, since this was more an introductory chapter? Also there is no schedule of sorts for this, unless the readers want more, but for now I will upload chapters at my own time.*
