Chapter 1: Destiny arrives

In a dark room, a boy no older than four, was watching his favorite video of his idol on his computer. This boy's name was Midoriya Izuku, he had a head of green hair and eyes, four freckles in a diamond shape marked each of his cheeks.

"All Might is so cool! I can't wait to get my quirk and be a hero like him!" Izuku didn't know it yet, but his wish was about to be granted.

The screen that showed the smiling mountain of a man began to flick, the image glitching, "What?! Oh no, if I break the computer mom won't let me use it alone again!" Izuku started to panic, and the feeling only grew as the screen turned black.

Little Izuku was almost crying when the computer lit up with a colorful glow, and from it an object emerged. Izuku watched in amazement as an egg almost as big as him came from the screen and softly landed in his lap. The egg was a light green color, and soft to the touch, giving a comfortable warmth.

"Wow!" Izuku looked at the egg with stars in his eyes, "That was amazing! I have to tell mom… tomorrow, because she'll be mad if she finds that I'm still awake." Izuku's excitement died down as he remembered he should be in bed almost an hour ago, as his mother told him.

Izuku carried the egg with him to bed and pulled his blanket to cover both of them, "Good night" Izuku said, and the egg seemed to warm a little more, as if responding to him, and that warmth lured Izuku to dream land.

The next day, Inko came to her son's bedroom, she was a young woman with green eyes and hair like Izuku. Opening the door she saw Izuku's fluffy hair poking out of the blankets, "Izuku time to wake up" she said while pulling the blankets, and what greeted her was the small form of her son… cuddling a green toy?

It was a small light green ball with a horn poking from its forehead and a long tail. Strange she didn't remember getting something like that to Izuku, he was always asking for hero toys. Her train of thought was interrupted by a yawn… that came from the toy.

It blinked the sleep out of his beady black eyes and looked at her, "Good morning!" Inko did the sensible thing in this situation, she screamed.

"Whaa!" That ended waking Izuku, who clenched the green ball to his chest, "What happened?!" He asked in panic.

"You're squishing me!" The ball cried, and that made Izuku realise what he was doing, and that the egg was gone, "Wait, where's the egg?"

"I'm here, I hatched!"

"So you came from the egg?" He asked.

"Yup, my name is Zerimon."

"I'm Midoriya Izuku, nice to meet you." While Izuku and the now named Zerimon were happily talking, Inko was already gone from panic, to worried, to entranced from just how cute the two were.

"Izuku, care to explain what is happening?" In the end, the motherly instincts won and Inko seated beside Izuku and checked to see if he was okay.

The boy happily told his mother of the events of last night, and Zerimon explained that when he hatched it was in the middle of the night, so he just went to sleep as there wasn't anything else to do.

"Okay, Zerimon right?" Inko received a nod (how a ball could nod was a mystery), "What are you?"

"I'm a Digimon" The two greenettes gave him a confused head tilt, sighing he explained, "Digimon is short for digital monster"

Inko was confused how something so cute could be called a monster, but she focused on the more pressing matters, "Okay, and why are you here?"

"I'm here because I'm Izuku's partner"

"Partner?"

"Yes like...ugh it's hard to explain, I think I'll leave that part to her."

"Who?" Inko was interrupted by the sound of the door bell, "That must be her!" Zerimon said while jumping on top of Izuku's head, "Let's go, she'll tell you everything."

Inko and Izuku traded a glance before the bell sounded again, they got up and walked to the door. Inko gave Zerimon an apprehensive look, one that the Digimon noticed. "Hey don't worry, she's nice, and if anything happens I'll protect both of you." That was enough to ease some of Inko's worries, and let Izuku star-struck at how cool he sounded.

Inko slightly opened the door, and saw standing in front of it a young woman with fair skin, purple eyes, short purple hair, and a large bust. She was wearing glasses with purple hexagonal lens, a white buttoned shirt with long puffy sleeves, and pocket on the left side of the chest, a purple bow tie, a black dress that accentuates her breasts and is open in the back with the straps forming an "X", black stockings, and high white boots with purple shoelaces and black soles, and was carrying a purple laptop finishing the professional look, "Hi, do you need something?"

"You must be Inko, can I come in? There is a lot I have to talk to you and your son about his new partner"

Inko spared a last look to her new guest before opening the door, "Come in"

The woman entered the house and Inko guided her to the living room where Izuku and Zerimon were watching the TV, the woman smiled seeing the two cheering for a hero. She walked to them and sat in a chair next to them, Inko taking the other side of the sofa that Izuku was on.

"Now I think introductions are in order, my name is Mikagura Mirei, but you two can call me Mirei, I was never one for formalities."

"Okay, Mirei-san, why are you here?" Inko asked.

"Because of these two." Mirei said, giving another smile to Izuku and Zerimon, "That and I promised Hisashi I would deliver some things to both of you."

"You know my husband?" Mirei nodded at Inko's question and gave her a picture, in it was Mirei and three other boys, each accompanied by a creature, one had messy black hair red eyes and freckles, he was wearing a black plain shirt, baggy jeans, red shoes and yellow aviator goggles that sat on his forehead. He was kneeling beside a red lizard with a white belly and with a black mark on it, both smiled at the camera.

Standing beside him was an older boy, already a teenager. He had red hair and blue eyes and was wearing an orange muscle shirt, cargo pants and combat boots. He had a small smile on his face and standing on his shoulder was a biped orange cat with similar green eyes, it had a yellow tuft of fur in its chest and a crown-like piece in its head that was on fire, the point of its tail was also aflame.

The last boy was standing on the first other side of them. He had green hair with blonde highlights, he was wearing a button up shirt, navy blue trousers and dress shoes. The boy had a serious face, but the slight pull of his lips show that he to was happy to be there, at his side was a floating gear, it had a golden outer layer and in the center of a darker metal, two red eyes could be seen from two holes in the metal, and a shaged mouth, that like the boy seemed to had a slight smile, two other small gears that looked like hands floated at its sides.

"That's my dad?"

"Yes Izuku, these are Midoriya Hisashi, Todoroki Eiji and Sasaki Mirai, they are the three best friends that saved the whole Digital World!" Izuku recognized the names almost instantly, jumping towards Mirei and almost making Zerimon fall from his spot in his head Izuku asked, "My dad is friends with Endeavor and Sir Nighteye?!"

"Yes, these three know each other since their childhood."

"Why didn't dad tell me that?"

"For the same reason he didn't tell you about Digimons and his partner, it was his duty as a Royal Knight partner to keep the balance." She answered.

Inko who was staring fixedly at the picture, finally got back to her senses and saw Izuku almost in Mirei's lap asking a million questions to her, and the woman doing her best to answer all of them, her smile never leaving her face.

The moment was interrupted by a growl, Zerimon blushed and scratched his head with his tail. "Sorry, I haven't eaten anything yet."

Inko stood up and started walking to the kitchen, "You both still haven't eaten, just give me a sec and I'll prepare breakfast, would you like something too Mirei-san?" Now that Inko's concern was dismissed, she promptly got back to her 'super mother mode', already thinking what to do to a boy in his growth phase and their new charge, while doing her part as a host.

"Just a coffee will do, thank you."

After Inko walked away Izuku took the picture once again, Mirei noticed how much the boy was missing his father and decided to cheer him up a little, "Izuku, I got something here for you."

She gave the boy a set of yellow aviator goggles, and Izuku quickly recognized them, "These are my dad's goggles?"

"Yes, he said to give them to you, that you'll need them for your adventure like your father needed on his."

Izuku stared at the goggles with moist eyes before putting them on, leaving them on his forehead, "You look cool" Zerimon said after jumping on the couch and giving Izuku a once over.

"I still have one more gift for you" Mirei opened her laptop and after a typing for some seconds it let out a glow, in her free hand a small device appeared, it was similar to a old tape recorder, with a ergonomic grip, two side buttons, in the center was a small hexagonal screen, below it was a d-pad and three buttons, and whole device was a blank white.

"This is a gift from our boss, your father worked so hard with us for so many years that he decided to make one specialy for you, it is called a Digivice." She put a hand in the side of her mouth as if she was telling a secret, "And between you and me, it's the best one they've made yet."

Izuku was curious of what the little device was, taking it from Mirei's outstretched hand, the Didivice gave a soft glow. Izuku was starstruck, the Digivece was now a forest green while the buttons and grip were red.

The screen lit up and project a holographic interface, Izuku didn't understand most of the symbols in it, the only thing he could read was the center screen where it was written:

{SYNCHRONIZATION COMPLETE}

"Wow"

"Don't be surprised, this is nothing compared to the digivices full capabilities."

"What can it do?!" Izuku exclaimed.

Any form of answer was interrupted as Inko came back with a tray with some sandwiches, orange juice, and coffee. Now both Izuku and Zerimon's stomachs growled, and in a second they were already digging in.

"Slow down you two, the food isn't going to run away." Inko slightly scolded the boys with an amused smile.

Mirei took a sip from the coffee, and any semblance of professionalism was broken by the delight on her face. "That is so good! You have to tell me how you did it!" She said while holding both of Inko's hands. Izuku and Zerimon snickered at that and Mirei quickly recompose herself and cleared her throat. "If is not too much trouble"

"Not at all." Inko decided to go along to help Mirei. After Zerimon devoured his last sandwich, he suddenly started to glow, startling the two Midoriya's. Izuku's Digivice that was on the table shook and projected another screen.

{EVOLUTION}

"Zerimon digivolve to...Gummymon!"

When the light died down, in the place of Zerimon was a slimy creature of the same color, eyes and horn, but now he had a stumpy body and two small ears. The Digivice shook again and another screen with an image of Gummymon appeared, a synthetic voice started to read a description below the image.

{Gummymon: Level In-Training, is a Lesser Digimon. It grew up from Zerimon. As it inherited an exceedingly energetic personality from Zerimon, it is both cheerful and lively. Although it is growing, it's squishy because its body tissue is as unstable as usual, but just like Zerimon, its horn portion has hardened, and it intimidates the opponent with headbutts. Its greatest change from Zerimon is that it has a body and ear-like objects coming out of its head.}

"Congratulations Gummymon!" Mirei said while lightly clapping her hands.

"Thanks!"

"What just happened?" Inko asked, confused. Seeing the opportunity, Mirei turned to Izuku, "Izuku could you please take your Digivice?"

"Hum? Ah okay" Izuku snapped out of his entranced state and grabbed his Digivice.

"Okay press the top side button and said 'evolution entry one'" Izuku did as she asked and a Mirei's voice sounded from the Digivice.

{Digimon evolution is a simple yet highly complex process, while the species in the Human World could take millions of years to do it, Digimon can do it instantly, changing forms to more powerful ones. This process is possible because as digital life forms, Digimon can use the data they collected to accomplish it}

That helped them with their current question, but ended causing a lot more. Mirei saw this and prepared herself for a long explanation


"So the Digital world is a world made of data of the Human World, Digimon are creatures also made of data, and my dad and his friends ended up in the Digital World when they were kids"

"Yes."

"They ended partnering with Digimons and saved the whole Digital World a bunch of times?"

"That's correct."

"And the reason they never told anyone about it, is because dad and Sir Nighteye are partners of Royal Knights and Endeavour is partner with one of the Olympus XII, and they are like super cool heroes that protect the whole Digital World?"

"Good to see you understood everything Izuku." Mirei gave the boy a smile. Meanwhile Inko was still trying to make sense of everything she was told, she got the important parts, her husband's secret job was actually of a other-wordly hero, which was the reason why he had to travel so much and spent so much time away from home, and her son got a partner like him.

"I have a partner too, so I can be like dad?"

"No Izuku" That made the boy's eyes water, but Mirei continued before tears could be spilled, "You can be even better"

"What?"

"Well why don't I let you see for yourself."

After a few quick taps in her laptop Mirei projected a holographic screen with Hisashi's face in it, he still had the same messy black hair and freckles, but the childish face of the boy in the picture was now a face of a man in his prime. The video began, and Izuku and Inko had their eyes glued to the screen.

"It's this thing on? Heh should be, well hi Izuku! If you are seeing this then you just got your partner, man I wanted to be there to see it! But well is how they say 'no rest for the wicked' so us good guys don't have any either" Hisashi laughed before stumbling, an explosion sounding in the background, "See can't even talk to my son in peace! Hey buddy can you take this elsewhere I'm recording a message to Izuku!" He shouted to someone off screen, getting a quick "OK!"

"Well where was I? Oh right, Izuku there are a lot of things you don't know about me, your mom too. I'm sure she will give me an earful when I get back" Hisashi shook a little with a fearful look on his face, "Well I'll take that beating when I get there, but back to business, you Izuku have something really special with you! Something better than any quirk in the whole world."

That got Izuku's attention, what could be better than a quirk? With one he could be a hero!, "I know what you are thinking Izu, but with a quirk you could only be a hero in the Human World, with what you got you can be a hero in both! Because, son you have the YMC sleeping in you, what does YMC mean? It means Yggdrasil Master Code, It is something the god of the Digital World created. Yup you got a god's most amazing creation on you, pretty cool right?" Hisashi gave Izuku a smile, while the boy looked at his hands in shock, Inko too didn't know what to do about this.

"I know you and your mother have questions but I don't have much more time to talk so I'll let Mirei explain the rest to you, but know this Izuku, you have a good heart and a brilliant future ahead of you. So live your life, make friends, and see everything these two wonderful worlds have to offer, and don't worry about a thing, because your old man will hold the fort until you are ready to show everyone the amazing person you are and the wonderful things you'll do!" Hisashi said with a proud voice, as if Izuku had already done all these wonderful things.

Holding back a sob Izuku hugged his mother, who was holding back tears herself, "And most important, know that I love you, both of you, now and forever." With that the recording stopped and the screen vanished.

Mirei gave the two a minute and Gummymon did the best he could to join the hug even without arms. After a couple minutes and lots of tears, the two greenettes calmed down.

"That's one of the reasons I came here today, the YMC is too important to be left unattended." Mirei sighed.

"Mirei-san, what is this YMC, and will Izuku be okay?"

"I understand your concern Inko, but there's nothing to worry about, think the YMC as a quirk, it'll be just another part of Izuku."

"So my quirk is the YMC, but what does it do?" Izuku asked, fiddling with his hands.

"Well Izuku, for a comparison, the YMC is like a computer programming language, and Yggdrasil was the programmer. They used it to make the Digital World what it is now, and you can use it too."

"Wow that's amazing! But, why do I have it?"

Mirei gave the boy a soft smile, "Your father originally had the YMC, Yggdrasil entrusted it to him the first time he was in the Digital World, but he wasn't compatible with it." She brought up a screen with an image of Hisashi with information of him, from his blood type to his personality, and blinking red was a small window written 'code integration 18%'.

"You Izuku, is a different case" The screen changed to show Izuku's data, and the previously red window was now green, the words were now 'code integration 100%', "The code synchronized perfectly with you, and that's why it passed to you."

"But how did it pass to me?" Izuku's innocent question was met with Inko's panicked voice, "I'll tell you when you're older!" Izuku looked at Gummymon who shrugged (how something without arms and shoulders could shrug was anyone's guess).

"In more important matters, I would like to help you with the YMC Izuku, and help you with what I can Inko, it's the least I can do for everything Hisashi did."

"You don't have to Mirei-san, we'll be fine on our own." Inko lightly objected.

"You're right I don't have to, but I want to, and you will see I can be quite stubborn when I put my mind to something." Inko sighed, and ended up accepting Mirei's offer in the end.

"Good, I would like to discuss some things with you, and while we do that, why don't Izuku and Gummymon go to the park Izuku usually go to play with his friends?"

"How do you know that?"

"The only thing Hisashi talks about is his son." Mirei giggled as Inko blushed, embarrassed by her husband's antics, "Okay, Izuku you want to go to the park?"

"Yes! That way Gummymon can meet Kacchan and the others!" Izuku hopped around excitedly.

"Okay you can go, but be careful, and come back before it gets dark" After fussing over Izuku for a bit, she let the boy and Digimon go after he changed into some outside cloths that consisted in green shorts, an All Might shirt and red shoes accompanied by his new goggles.

"Don't forget your Digivice!" Mirei handed the boy his Digivice.

Izuku looked at her confused, "Why do I need to take it along?" He asked.

"A Tamer should always have their Digivice with them, your father learned that the hard way." The boy gulped and put the green device in his pocket. Inko led Izuku to the door after making sure he was ready.

"Bye mom!"

"Bye!"

Izuku ran down the street with Gummymon on his head, he couldn't wait for his friends to meet him! Even though he knew his Digimon partner for less than a day Izuku already considered him his best friend. It was like they knew each other for years and only now were reunited again, it was as if they completed each other.

After a quick run, the duo reached a park with lots of trees. It was a small piece of nature in the middle of the city. In the borders there was an open space where children normally played, but now a trio of boys were beating another one.

Izuku was shocked, one of the bullies was his friend, he could recognize the spiked ash blonde hair and the sound of explosions anywhere. The emotional turmoil didn't stop Izuku from running at them, against Gummymon protests.

"STOP!" Izuku shouted while putting himself in front of the beaten victim, and in the path of the three bullies, "You're hurting him!"

"Yeah, back off!" Gummymon said, the natural protective instincts of a Digimon to its partner going overdrive like Izuku's own instinct to help others. Unknown to them, the Digivice in Izuku's pocked started to glow.

"What is that thing Deku? Is your quirk a stupid slime? That's almost as useless as you!" Bakugou and the other boys laughed while Gummymon fumed, more towards the insult to Izuku than the one to him.

"Get out of my way Deku! That bastard said his quirk was better than mine, so I need to teach him a lesson!" The aggressors closed in on Izuku, and that was the breaking point to Gummymon. He jumped from Izuku's head, the boy's desire to protect was matched by the Digimon, the Digivice burst with light with the power of their will and Gummymon was enveloped in the light.

{EVOLUTION}

"Gummymon Digivolve to… Terriermon!"

Izuku could hear the synthetic voice of his Digivice in his head, describing his partner's new form.

{Terriermon: Level Rookie, is a cute bipedal canine with white fur that is striped with green on its collarbone, paws, and the tips of its ears. Its most prominent features are its long, frayed ears and the solitary horn on its forehead. Like a dog, it has black toes and paw pads. While it is primarily reminiscent of a dog, it necessarily shares design elements with its twin species, Lopmon, who is reminiscent of a rabbit.}

Back at the Midoriya family apartment, Mirei suddenly looked at the window and gave a soft smile, 'Looks like the apple didn't fall far from the tree after all.'

Back in the park Terriermon landed in the way of the three charging bullies.

"I won't let you hurt my little bro! Petit Twister!" Terriermon spinned his ears like a propeller, generating a tiny tornado that pushed the bullies back. The other kids in the park watched in amazement as Izuku and Terriermon stood against the downed bullies.

"I don't know what the hell was that, but now you're dead!" Bakugo got up and runned at Terriermon with his hands cracklin with explosions. Izuku saw his partner in danger and was about to run to help him, but Terriermon just gave him a smirk and said, "Watch how a pro does, Bunny Blast!"

Terriermon took a deep breath and shot a blast of superheated air on Bakugo's hand, that made the natural nitroglycerin he secreted ignite. The sudden explosion sent the blonde to the ground again.

The two cronies, after seeing their leader defeated, turned tail and ran. Bakugo got up again, his hand burning with pain, he snarled at Terriermon, but the green Digimon wasn't even slightly intimidated. The small audience started to comment on the fight.

"Midoriya beat Bakugo!"

"That bunny is so cute, I wanted to have a quirk like that!"

"Finally someone put Bakugo in his place!"

Bakugo was furious, but he wasn't stupid, he started to walk away after giving a last heated glare to Izuku and Terriermon, "This isn't over!"

"I'll beat you as many times as you like firecracker!" Terriermon said to the retreating blonde. The Digimon then walked back to Izuku, who was helping the boy that was being bullied to stand.

"Are you okay?" Izuku asked.

"Yeah, that was really cool, you looked like a team of heroes!"

Izuku blushed at that, while Terriermon put his hands in his hips and puffed his chest. The boy walked away and left the partners alone, the other kids in the park giving them space.

"You Digivolved again!" Izuku pointed out.

"Yup, I'm Terriermon now!"

"Yeah, the Digivice told me about you"

"Aw, that ruined the surprise!"

The two laughed, when no one else approached them the duo began to play by themselves. They played for hours, laughed, and enjoyed each other's company. When the time came for them to go back, Terriermon jumped in Izuku's head again. The Digimon's significantly larger size almost made Izuku fall, but the green bunny spread his ears, using the wind to lift the boy up.

They laughed while doing their best to keep balance, Izuku spread his arms. The whole way was full of stumbles and laughter, and that marked the beginning of their adventure.
