My first fanfic and my first story guys! Updates are every week! No patreon or monetary gain from this at all either, this is purely for the reasons to tell a story, so I appreciate the reads! We'll travel to multiple different worlds but rest assured, I'll make sure to flesh them out 100% of the way.

Ollivanders

"Alright, Yumi, we're leaving," My mother exclaimed, her enthusiasm palpable as she coughed out a delicate butterfly, and I couldn't help but laugh. "It's not right to laugh at your mother!" She started whining, tugging at my aunt's robes. We were now outside the store, the stunning red-haired witch guiding us. I held up the velvety black box containing my egg. She had charmed it so that only I could open it, cautioning me to keep my familiar hidden until it hatched. Apparently, in its current state, it hadn't accumulated enough magic to establish a connection with me. I mentally shrugged.

'I wish someone would try to. No, I'm being serious, I wish someone would'

I would need to practice my moves on someone after all. Ah man, now I'm getting excited thinking about it. Knowing damn well I haven't practiced Limitless or Reverse Curse Technique yet. When do I get to fight??

My Aunt sighed and patted my mother's head in a comforting gesture. She stood a solid two heads taller than her, making her about 6'5", though I had never been one to pay attention to height details. Nevertheless, she was by far the tallest person I had ever seen in this world. "There, there, I'm sure your son thinks you're the best," my Aunt offered, her smile clearly laced with sarcasm.

"I hate you, You old hag" my mother shot back.

My Aunt couldn't help but laugh. "We both know that's not true, dear. You love me," she replied, placing a hand over her heart in mock sincerity. "Don't make me bring the butterflies back." She wiggled her hands, a butterfly flying threateningly close to my mother's face.

My mother stomped away, snatching my box and tossing it into a conjured suitcase before grabbing me by the shirt and dragging me along. She shouted over her shoulder, "Hmph! And you're going to tell me what happened the night he was born when I came back! This gatekeeping information needs to stop!"

I managed to free myself from my mother's grasp, leaving them to shout at each other as we turned a corner. Just before I lost sight of my Aunt, she shouted ahead to me,

"I love you, Yumi! Take good care of your pet! We'll be seeing each other again!"

I waved back, her smile brightening my already upbeat mood. "Thank you! Love you too, Auntie! Don't let Mom call you a hag!"

"You're supposed to be on my side! Urggh see, Already becoming a bad influence!" She quickened her pace as we once again set on the cobblestone streets, the fairies giggling as they bid me goodbye.

[Ollivanders Wand Emporium]

Ollivanders, the iconic wand shop of Diagon Alley.

It had an aura of ancient charisma as one stepped through its creaking doors. The narrow, dimly lit space was lined from floor to ceiling with countless boxes, each holding a wand destined for a wizard or a witch. The polished wooden shelves, warping with age, seemed to stretch endlessly, the wand boxes stacked in a haphazard yet oddly organized manner.

The air was thick with the scent of aged wood, ancient parchment, and faint traces of magical enchantment. Shafts of dusty sunlight filtered through the grimy windows, illuminating particles of floating dust and lending an eerie, almost metaphysical quality to the shop. The floorboards creaked underfoot, secrets of centuries gone by.

Amidst this enchanting chaos sat Mr. Garrick Ollivander, the venerable wandmaker himself. He stood behind a worn, cluttered counter. Thin and having a stooped figure, Silver hair that cascaded down to his shoulders, and a face lined with wisdom. His pale blue eyes held a spark of unending curiosity, like the depths of the very magic he harnessed. His long, delicate fingers danced with a grace that came from years of crafting wands, as he meticulously examined the core materials, lengths, and flexibilities of the wands that were the heart of his passion.

His robes, though well-worn, bore an air of timeless elegance, their fabric shimmering with a faint glimmer. His piercing gaze seemed to pierce through the veils of one's soul.

Amidst the maze-like expanse of wands, Mr. Ollivander was one of the guardians of the most intimate and powerful tools in a wizard's life, while also the steward of secrets and stories, as they were whispered by the wands that lined his ancient shop.

"Hello, Hello!" He was knocked out of his stupor by a starkly feminine voice. One that he recognized. He looked up, being greeted by the Queen Of Charms herself, Aesira Concordia. And a child with piercing blue eyes, as much like his own, seemed to pierce through veils.

[Yumi]

'Why for some reason did I think he would look different?' I wondered. My mother shook the man's hand in greeting, but I could sense a degree of silent reverence in their exchange. Again, I was left in an awkward trance, but no fairies were there to capture my attention.

Mr. Ollie, this is my son, Yumi," she said, motioning for me to approach the front desk. Mr. Ollivander nodded in acknowledgment and extended his hand to shake mine. "So nice to finally meet you, Mr. Concordia. Your mother has been instrumental in retrieving ingredients for me back in the day. Quite arrogant, but a heart of gold indeed," he added with a knowing smile.

My mother blushed and playfully slapped the man on the shoulder in embarrassment.

'Aww, first Auntie, now Old Ollivander. She can't catch a break,' I thought.

I reached up to shake Mr. Ollivander's hand, wearing a comical smile. "Nice to meet you, sir. She sure can be a handful on my end too. I'm lucky to have survived this long, fortunately."

In an instant, a torrent of hearty laughter escaped from the Old Wandmaker's lips. My mother shot me a glare that promised to linger for the entirety of our little exchange, clearly not appreciating my comment. She slapped me upside the head, but it was in vain, as I joined in too. She hung her face, "We should've never come here". She shook her head in hopelessness.

After he composed himself, the man promptly asked me a few questions. "What is your dominant Arm?" He asked, bringing out a tape measure to get the length of my arms. "Left" I stated, his blue eyes analyzing what lay beyond my understanding.

It was magical, but slightly off-putting as he shuffled from place to place in subtle anxiety, mumbling up a storm. "Hmm," He grabbed a box from the uppermost part of his shelves. He opened it, pulling out a light-beige colored wand. "Ash Tree, Pheonix Core. 10 inches, a little bendy" He announced, placing it in my hand.

As I anticipated, It promptly didn't do anything remarkable. It shook in mild discomfort but didn't outright flay any stray magic. I appreciated that immensely though. The wand-maker abruptly snatched it away, once again mumbling. My mother was looking on in disdain at the scene.

Clearly, her distaste for wands was showing itself. Maybe it was in an attempt to not make decisions for me, but truly I wouldn't mind spending the remaining school years without one. Only then I'd have to reveal my hacks, which would no doubt be entertaining, but not yet. Gotta reveal myself with a bit of flair you know? The only thing I'm not certain about is if I could protect myself against Imperio or Mind Reading.

I'm not Yuuji, as he was able to contain Sukuna and drive himself away from his influence. The series made it clear that if it was anybody else, they would've either died (best AND worst case scenario depending on your point of view) or been taken over. Sukuna was just unlucky in that aspect.

Or lucky, depending on how you look at it.

I shivered at the thought. Stuff like love potions be damned. To hell. The King Of Poisons perk would work well with that. Maybe till I got things like Occlumency I would be confident to show myself to the world. Voldemort casting imperious, demanding me to kill myself, and catching a wizard's eye contact on accident was enough to calm me down from cutting loose. Reversed Cursed Energy is amazing, being able to heal entire body parts and fatal blows, but it wouldn't do shit if I was under a mind control spell before I could even set my mind on reversing whatever happened. Man, I don't even know how to activate positive energy at the moment.

I could theoretically be blitzed with a mind attack right now.

Hell, what's stopping an Avada Kedavra if I was hit by it? Sure, I can dodge it with the form I have, which is a last resort, And infinity, which is admittedly solid. But what happens if I was caught off guard or a super powerful wizard decided to show themselves?

Moral quandaries and the like are made moot because they're too strong to give a damn, spamming unforgivables, somehow bypassing infinity for an unbeknownst cause. Hollow Purple is a broken offense, but I'm not the only one who can simply teleport out. Apparation exist. Domain expansion and Sukuna form is my only trump card at the moment right now probably. If I could gamble on this world being chock-full of mediocre humans with sticks that shoot lights out of them, I wouldn't. I'm not gambling my life on a hunch. I have to be prepared. Learning Infinity and Occlumency should be a priority.

Avada quite literally separates the soul from the body. I'm pretty sure Azathoth said nothing about second chances, and that things omniscient. It would've said something if I was dumb enough to think I would respawn or something foolish like that. Since my Mother and Aunt exist, there were probably more consequential wizards roaming about this world, among them being Voldemort himself. I can't just up and assume everything is like the original films or books.

I briefly wondered if Cursed Energy was Inferior to the whimsical and unpredictable habits of magic. Maybe I had more to learn than I realized. Seeing my mother and Aunt's subtle use of it was enough to inspire envy and even awe from me. But among them all is determination. Making things appear out of nowhere? Nonchalantly summoning animals from absolutely nothing? It was ridiculous. Edward Elric would froth at the mouth at that, thinking it would be the doings of a philosopher's stone, bypassing the laws of equivalent exchange, but nah.

'It was true magic'

Broken as all hell.

And once again, I being Icarus, did the smart thing and flew back down.

Maybe that's the true reason for the Blind Idiot sending me here. An Introduction to Magic. If I didn't choose Gojo and Sukuna's abilities and instead opted for a magic type one, would the world I'd be going to be different? Would I have been in the streets of Yharnam or the School of HighSchool DXD? Or perhaps even JuJustsu Kaizen itself? Food for thought.

Well, my goal is to say I can beat Dante and Vergil from Dmc in a 2v1... Yeah, I'll go with that.

Wand after wand, from Alder to Apple tree, Blackthorn to Cedar, Black Walnut to Elm, even Cherry tree and Cypress. Oh my, was Cypress the most amusing. It practically jumped and self-destructed at my touch, causing a whole bookcase of wands to fall flat on the floor. Well fuck you too? I mean, it must be sad being butchered out of a tree and forced to wait for someone to pick you up out of boredom, to only then be used as a tool forever. Must be hard. Piece of bark.

My frustration showed itself, Ollivander paying no mind and my mother snickering at my ire. "This is exactly what happened when I got mine, amazing isn't it?"

Oh well, I'll get her back later somehow.

Then Finally, it happened

"One of the rarest tree woods I'd ever had the pleasure of crafting from. A material your mother helped salvage on the island of Socotra in Yemen, The wood of the Dragon Blood tree."

He then pulled out a long and beautiful wand, pure white with red streaks traveling up and down its body, as the woodwork was exquisite.

My mother smiled as he spoke, "Or as your mother would like to call it, Mening Olovim. My Fire. 16 inches, Flexible and rigid, with a Dragon Heartstring of course." He declared, Placing it in my hand once more.

A myriad of sensations washed over me. The wand thrumming and pounding with energy, a thump of a heartbeat I likened it to, a shared essence of the magical creature within its core. A shiver ran down my spine, my senses finely attuning themselves to the quality of Magic that was present in the air. At best, I could describe it to be as if you were in a noisy area. For example, a crowded park. As kids played, as dozens of people laughed and exchanged pleasantries, then, for an inexplicable reason, they disappeared. Like a vibrant painting suddenly drained of all its colors, leaving behind only the stark, empty canvas of silence.

My eyes widened, and a smile, one that seemed to reach into the depths of my soul, would break across my face. It was a smile of recognition, of unity as I felt for the first time.

One of the energies of the multiverse that bound it together, were now resonating with me. It claimed me.

Small sparks of colorful magic would dance around me, creating a breathtaking display of light and power. I had become one with my wand, an overwhelming sense of confidence and purpose danced across my being, reminding me of the journey ahead.

"Flawless transition, I have to say, Mr. Concordia. Good show," he said with a smile, elegantly placing the now-empty box in its corner. "Took about 20 tries for that. Almost had me thinking we would be here for hours," he added with a playful wink in my direction, and then he turned his gaze toward my mother. "He really does take after you in some ways, doesn't he?" he inquired.

In response, my mother simply hugged me tightly. "That's my son. I would have preferred you to be wandless, but a powerful one should at least grace your palms. Thank you, Mr. Ollivander," she said, offering a respectful bow. The old wandmaker reciprocated with a bow of his own, and I followed suit.

"Hopefully, you'll go far with it, even if just for a little while," Mr. Ollivander chuckled. "As we both know what you may be capable of, Mr. Concordia."

After I straightened up, I flashed a knowing smile toward him. "Oh, you have no idea," I beamed, feeling a bit embarrassed.

My mother took the opportunity to fix my hair, drawing my attention away from the man. "Oh, I'm sure," he replied. "Don't be afraid to ask for assistance. I've seen strong wizards over the years, many young and promising like you, fall due to arrogance or isolation. As we, the strong, grow in capabilities, we tend to think we're better off on our own. Don't make the same mistake, Mr. Concordia, as you no doubt have the potential to surpass the world itself."

His words carried a heartfelt wisdom as the message was clear. Strength should be tempered with humility. Go figures.

Voldemort must've been rough on him.

"I won't dissapoint you Mr.Ollivander. Or Mother." I hugged her back, causing her gaze at me, an unreadable expressed painting her features.

After paying a total of 7 galleons for the wand, my mother and I bid Mr.Ollivander farewell, his keen blue eyes never losing their glow as we said our goodbyes. And once again, we were set on the cobblestone path.
