So timeline wise the Izuku we are all seeing is after his internship with endeavor, and before he knew about the war, because of this, he doesn't feel much of an urgency to get back home like he would if he did know about the war back home, anyway that's my excuse for the time being, and before anyone asks, yes Izuku will get Derflinger.
A familiar feeling washed over Izuku, and with a groan his eyes opened, but instead of being meet with anything he would aspect or wish to wake up to, he woke up to a face above him, it was a girl, green eyes met silver eyes, it took a moment but it was than that Izuku realized just how silver the girl was, her hair was silver, her skin looked metallic, reflective even, and then she spoke.
"Hello master." that woke Izuku up, and with a quick jerk and scamper his back was pushed up against the oddly steel wall, and with a blink he realized that a bed was beneath him, the frame made of metal and the sheets were a silver color, his confused gaze turning to the girl, who he now realized was wearing armor.
"I'm sure you are a confused master, but admittedly this is the first time this has happened." The wording peaked Izuku's interest, while hearing someone call him master made him extremely uncomfortable, the fact that she seemed to also be confused helped him calm down slightly.
"W-who are you?" Izuku asked hesitantly.
"I...my name is Gandalfr, also known as the left hand of god, one who is bestowed upon a human vessel to be able to properly wield my power, usually in the form of runes on the person's left hand, and I have had many vessels but none before have been able to enter my sanctuary like you have, though I can only assume that the spirits that reside within you allowed this to happen." that... strangely made sense to Izuku, if anyone were allow him to enter a spectral world, it would be the predecessors, a pang of longing shot through him, he had to get back home, he was a hero, but evidently, the girl now named Gandalfr noticed this.
"I...am aware of your conflicted feeling's, normally the vessel I am bonded to gets compelled to listen to their master, but with the interference of your power, the natural compulsion the rune gives off has been turned null against you." Izuku felt a spark of defiance enter him, she would use compulsion to force someone to stay in this world!? His eyes set and he stood, posture defensive, but a single hand from Gandalfr made him pause.
"Do not be mistaken, I'm actually quite happy you are unaffected, when I was made, I was made with a conscious that influences and is influenced by emotion, but I do not get to choose who is my vessel, and it is not me who compelled my vessels, it is the sanctuary you see around you that compels them, enchanted and set in stone by the god Brimir." Izuku took a moment to take this in, apparently gods existed, of course this wasn't much of a stretch when he considered that eight spirits resided in him, the fact that he was transported to another world, and magic existed, of course he questioned the validity of that statement, but her voice sounded ernest when she said she was happy he was unaffected, also the fact how her face seemed to be somewhere between devotion, anger, and sadness when she said the name, he was also pretty sure he had heard Louise say the name Brimir one or two times in her rants, but at that moment, he had more pressing issues.
"Why...do you look so sad?" this apparently caught Gandalfr off guard, as she looked surprised, but her face quickly became somber.
"For the fact you are the first person I have talked to in nearly hundreds of years, and you are going to wake up soon, I will answer your question, when I was made, I was crafted by Brimir, and as I am influenced by emotion, I have come to realize that the actions that I am forced to do, are things I do not want to do, but I have no choice in the matter." her voice was low and somber, and suddenly the room began to shake.
Izuku was unsurprised by the shaking, he was smart enough to realize he was waking up, but he had one more thing to say.
"Well then Gandalfr-san, if this is not the life you want to lead, then I will free you from it, I WILL save you!" with that parting message Izuku woke up, but from Gandalfr's perspective, it was different.
His form began to disappear, determined and defiant eyes staring into her own even as he fully disappeared, before finally his presence was gone from her sanctuary, his words echoing throughout Gandalfr's sanctuary as the light he cast disappeared, leaving Gandalfr huddled up in the cold darkness of her prison, her mind wishing what he said was possible, but her heart knew, there was no defying the god, Brimir.
Izuku's bleary eyes opened slowly, the conversation he had with Gandalfr still rolling around in his mind, his body much more slower to start than his mind, and finally his eyes were able to process everything, he was in the hay bed Louise 'gave' him, herself asleep on her bed, quietly groaning as he stood he stretched as he watched the sun slowly rise outside of the window.
Izuku was unsurprised about that, his conversation with the other predecessors, though few, usually only felt like a couple seconds, but lots of time could pass in the waking world during that time, and with a shake of his head he made his way to the door, prepared to do his morning workouts.
As he got outside he took a deep breath of the air, letting it sink into his lungs before his eyes snapped open, letting them wonder before settling into a runner's stance, and then he was off, feeling the air ruffle his hair as he began running next to the wall, settling on doing at least 50 whole laps around the place since it was smaller than U.A.'s track field.
Louise quickly pushed herself up as a rancid smell hit her nose, looking around quickly she found the source of the smell, in one of the dirty clothes baskets, originally empty, was Izuku's clothes, soaked in sweat, a frown pulled at her lips at the horrible smell, but before she could do what she wanted,(berate her familiar and get a maid to remove the horrid garments) the sound of a door opening caught her ears, looking she quickly found her bathroom's door opening, and stepping through was Izuku.
Louise was glad he at least had the decency to wear a pair of pants, sadly for her that was all he was wearing, so as she looked over, her mind went momentarily blank as her mind only processed the world muscles, over and over again like a mantra, but she finally snapped out of it as he put on a shirt.
"What are you doing you dog! never mind I don't care, get rid of those foul smelling clothes, and no food for you!" Louise yelled, kicking the basket of his clothes at him, which he caught, before shoving his confused body out of the door before slamming it closed, a confused Izuku simply looking at the door before shrugging and going off to clean his clothes, a very heated Louise on the other side of the door trying to calm down.
Her cheeks were dusted pink, face anger fading from her face as her embarrassment took over, she was in a school of magic, and a nobel, most boys she had met where squishy in a word, lacking no muscle and only having baby fat on their bodys, but the eye full she had gotten had none of that baby fat, only solid muscle had greeted her, and she felt like she betrayed herself as a thought whispered that most likely her fiance did not even look like that, but she quickly tried to shake the thoughts away as she dressed to go to breakfast.
Izuku was outside, wearing a pair of pants and a shirt that he had gotten from the commoners of this place after seeing how sweaty he was, and had lent them to him, but Izuku had a sneaking suspicion that they didn't intend to take them back from how they first tried to give him them, but after he refused just taking them they had changed their wording, forcing him to take them.
Clipping his actual clothes to a clothesline to let them dry he turned, hearing someone approach him, and was surprised to find the maid he had helped from before.
"Hello 'Our Fist' if you would please follow me." The name was no surprise to Izuku, even if it did weird him out, but as he had met the commoners of this place before, apparently with his win over Guiche, he was apparently the first commoner in history to win against a noble, resulting in the nickname.
Following behind the maid he quickly found himself in the kitchen, where he was quickly introduced to the head chef, Marteau.
"Haha! It's great to finally meet you 'Our Fist!', because of the noble brats, familiars are not allowed to eat at the table's, so please, dine on the leftovers we have here." With that, the maid from earlier came up with a cart full of food, quickly placing it all on the table, there was a large variety of food, there was stew, curry, and many other dishes, and because Izuku had worked out not too long ago, he began to dig in.
If Izuku was anyone else the large amount of food would have been preposterous for him to eat, but one thing that was useful was that he had a stock pilling quirk, All Might had told him that while OFA won't do much besides the all around enhancement and what Izuku had discovered, something interesting was that, while small, any and all foods eaten were used as more energy, so even if Izuku ate double his body weight, all the food would go straight to his quirk, leaving him with all of benefits of the vitamins and proteins and such with none of the downsides of increased fat, so with that thought, Izuku soon polished off every plate the kitchen had given him, leaving a thank you and many chefs baffled in his wake.
As Izuku wandered along, trying to get a sense of the layout, he suddenly bumped into someone, a grunt filled the air as they fell, and as Izuku looked down, he was met with the fearful form of Guiche, who suddenly yelled out.
"P-please don't hurt me!" Guiche cowered before Izuku, his form shivering in fear, making Izuku frown at how much it reminded him of himself, but just as he remembered that, he remembered what Guiche did yesterday, so he kept his mouth shut and planned to just walk away, but than a thought hit him.
"Hey...Guiche right? Do you mind telling me why everyone here call's Louise 'Zero'?" this had been bothering Izuku for a while, but if it was what he thought it was, he would rather not ruin what good faith he had with Louise by asking.
This obviously confused Guiche by the look he was giving Izuku, but as he stood up he had a look of realization, and gave a Izuku a smirk, but as their eyes locked, the momentary confidence withered as he seemed to remember his fear if Izuku, and stuttered out.
"L-Louise is called 'Zero' because of her zero percent success rate with magic, currently she is the only known noble incapable of doing magic properly, of course the only reason she even made it to her second year is because she is number one in every class when it comes it magic theory." Izuku blinked, robotically walking away from Guiche, ignoring his hesitant call's as he walked away, his mind rolling over what he had heard, how deeply it cut hearing that someone was in a position he was in so long ago, and that person had summoned him of all people, the thought made Izuku pause.
His voice was quiet as a mouse, as soft as a passing breeze, "How ironic, that the girl who is called 'Zero' summoned the boy that is called 'Deku', fate has a funny way of working, huh?" Izuku spoke to himself, gazing up into the blue sky as his mind wondered, but soon a thought struck him, he was stuck in a world that was not his own, with no way of getting home, but at least he could save someone who is just like him...right?
With that thought he blankly continued to walk, he was in another world, but that didn't stop him from being a hero the best he could in any situation.
Izuku looked at Louise blankly, letting her words settle in his head, almost feeling whiplash at her reasoning, apparently she wanted to go to the town nearby, and was taking Izuku with her to buy a sword so that he can protect her, Izuku's conversation with Gandalfr had lead him to ask around and finally Colbert had told him that anyone deemed Gandalfr has a mastery of all weapons, so while any sword she got him he could use perfectly, he was still utterly confused on why she wanted him to have a sword, especially after he had shown he was fully capable using only his fists.
"Why a sword?" Izuku questioned, completely lost.
"Because! Even if you can punch things hard, you atleast need a sword to give an appearance that you are not someone to be messed with." Izuku rolled her reasoning around his head, it had a few holes in it, mainly his very disarming face and personality, but he could sort of see how him having a sword, even if he never used it, would be useful, so with a nod they both went to the entrance of the academy.
Louise side glanced Izuku, she was riding a horse, and embarrassingly Izuku couldn't understand how to horse ride, but while she was at first skeptical, she was silently impressed as she watched him keep pace with the fastest horse at the academy, simply running along side it, and as they got to the town and she dismounted the horse, she was shocked to find it rubbing it's neck against Izuku affectionately, the horse, while having no name, was the most temperamental horse the academy had, and it only slightly respected Louise, simply because she proved to be a stubborn as it, allowing her to be the only one to ride it, but for it to show affection, it must have been deeply impressed with Izuku, but she brushed it off as she quickly lead him into the town.
Izuku looked this way and that, looking around as people passed, the architecture was as old looking as he expected, and as Louise lead him into a shop, he was greeted by multiple different weapons, as well as a man behind the counter that looked more like a rat than Nedzu, as the man and Louise talked Izuku looked around, pausing to raise a confused eye brow at the clearly ornamental sword the shop keeper showed Louise, and as he looked around he suddenly felt a itch in his left hand, and as he felt like he was being guided, his hand met the pommel of a sword.
Drawing it's sheath it appeared to be rusty, but closer inspection showed that the sword was perfectly usable, only a odd cocoon of rust around it's blade, but even then the edge was sharp, and looking at the rest of the blades revealed that the blades were dull, so with a nod Izuku picked up the blade, intending to just clean the blade, but as he approached Louise, something else caught his eye.
His eyes gazed at the obvious pair of gauntlets and boots, both gleaming silver with black highlights, giving them a surprisingly sleek look for the day and age they were in, and after picking them up he could tell they were fairly heavy, and if not for his strength training, he most likely wouldn't even be able to pick them up, but a voice then caught his attention, mainly the shopkeepers voice.
"How in the hell are you able to pick those up!?" the shopkeeper's voice yelled out in surprise.
"Hmm?" Louise strolled over, looking over the pair of armored boots and gauntlets Izuku was holding, "Izuku, how heavy are those?" she voiced her thoughts, thinking it was the only reason the shopkeeper would ask how he picked them up.
"I'm not sure, maybe a couple hundred pounds?" This answer not only shocked Louise but the shopkeeper as well. But the shopkeepers face suddenly went surprisingly stony.
"Hey kid, you intend to get that blade as well as the gauntlets and boots right? Well let's make a deal, I want that sword gone, and those gauntlets and boots, not a single person who has ever come into this shop can lift those things, and the sword is so rusty that people usually return it the next day, so how about this, I'll sell you the sword, the gauntlets, the boots, and this for 100 gold." the shopkeeper suddenly took out from the back a somewhat big looking suitcase, and placed on the glass, "this thing was given to me with the seller of those boots and gauntlets, no clue what's in it because the latch is so damn heavy, apparently the suitcase is enchanted to be lighter than anything on it or inside of it, no clue how it works but I don't care either, just that the person wanted both the boots, gauntlets and this case to be sold to the same person." as Izuku's eye's widened at both the price and what he had been told, Louise suddenly leaped forward.
"We'll take them!" with that resolute should she dropped the pouch of gold into the greedy shopkeeper's hands, picking up the suitcase as Izuku quickly strapped the boots and gauntlets on, and as he attacked the last latch on the gauntlets, the combined weight of both the gauntlets and boots suddenly disappearing, but a single step told him that the combined weight only stopped affecting him, as the wood beneath him creaked ominously.
Picking up the rusty sword he walked behind Louise as he attached the strap she handed to him so he could hold the blade on his back, like any normal person he would have put it on his waist, but when he put the blade at his waist the blade was too long and dragged across the ground, so onto his back it went.
When they got back to the academy they both went up to Louise's room, but as Izuku began to climb the stairs, he ominous creaking sound that happened every time he took a step made him pause, before looking at Louise for help, "Stop being a baby, the whole place is reinforced, not for specifically suddenly heavy people like you, but every floor of this place is reinforced to where you could jump on the top floor and not go crashing through, now follow me, with that, Izuku quickly followed her into her room.
Izuku hardly struggled as he lifted the clap's keeping the suitcase closed, while the shopkeeper was telling the truth about it's weight, it was much lighter than the boots and gauntlets and as Louise did this and that, he opened the suitcase, only find odd looking gems inside, they looked inexpensive, but their odd shape made Izuku ponder, but he was broken out of thought when he heard a unknown voice.
"My them gems are powerful, wonder what they be doing in their?" looking to his left Izuku was met with the blade, bouncing up and down as though mimicking speech, the voice obviously coming from it, Izuku could only balk at it before yelling, "WHHHAAAATTTT!?"
AN-
And that's chapter two, added this and that to make the story more interesting, adding a bit more depth in how the plot is changing compared to the original, but for the most part this chapter is not really an intermediate chapter, it's more i'm setting stuff up for the gears to start turning.
