Tobio?"-nd don't forget! There are only sixteen days until the graduation exam, so make sure you're all prepared for it!" Iruka's voice spoke out, to a cssroom full of raptly attentive children.

  Each and every one of them had been working toward this goal for years. Training, evaluations, sparring, all of it building to a fever pitch for just this moment. It was something to behold, or so Tobio thought, gazing back at the crowd of rambunctious children.

  Granted, he had very different feelings on the matter. It was one thing to watch a bunch of kids get into life or death situations through the medium of animation, and a very different thing to realize that before long you were going to be expected to be one of them. Maybe if he'd been the same boy that had gone to sleep the night before, this sort of introspection wouldn't have come naturally to him.

  That was no longer the case, though.

  Waking up in the morning had brought with it confusion. An initial burst of shock, as he tried to make sense of where and when he was, in the lonely apartment Nakamura Tobio kept on his own. Before, he'd been an excitable, fresh-eyed trainee, eager to take the graduation exam like the rest of his peers. Now?

  He was something else, someone else. Right now, he was assuming that he'd fused with the original owner of the body. It was more patable than the thought that his soul had boxed out a twelve-year-old, and taken possession of it for himself. For…whatever reason, why he was in punch-wizard nd, in quite possibly the shittiest isekai he'd ever heard of.

  "Yes, sensei!" The css responded as one, different levels of volume joining together in a cacophony. His voice was alongside theirs, even if there was a particur cking enthusiasm in his tone.

  Then again, considering the circumstances, Tobio was fairly sure he was allowed a little bit of bellyaching.

  Nakamura Tobio, twelve years old, Ninja Registration Number 068005. Orphaned in the Kyuubi attack, he enrolled in the shinobi academy for ck of better prospects. There were no secret bloodlines hidden inside his body, at least not from what he could feel. Just…a hollow, waiting to be filled, curiously enough.

  It was the expected, respectable thing to do for someone in his situation. After all, the academy was generous with giving out a stipend for training students. Just enough to survive on, and compared to the lifestyle of your average worker, shinobi were gmourized in every walk of life in Konoha.

  Why wouldn't they be? Who didn't want to be a respected warrior, able to clear out a battlefield with some ultra-powerful jutsu, save princesses, go on adventures to new and foreign pces? If he'd grown up in Konoha, with no outside knowledge of the world, it would have seemed like a plum picking.

  "Css dismissed!" With that, the gaggle of children did as kids were wont to do when let out of school and rushed to get out of the building. Of course, he had more reason than not to haul ass away from the academy.

  Hell, some of that propaganda was even true. It just glossed over the messy realities of shinobi life that he was painfully aware of. Konohagakure was set to be attacked, and parts of it leveled, at least twice in the next few years. That was before you got into the various other crises, border skirmishes, wars, and conflicts that were about to fre up across the world.

  In an ideal world, he would have just had some storied cn bloodline to fall back. Hell, even being a Nara would have been preferable. But as far as he could tell, besides that strange hollow inside of him, there was nothing particurly special about Nakamura Tobio. The boy's sole cim to fame during the story?

  He accidentally made Naruto and Sasuke kiss by being clumsy. That's it. From Tobio's complete and utter ck of presence in the rest of the manga and anime, he was a nobody in every sense of the word. Given the fact that he'd never been shown with a Jōnin sensei, it could be presumed that he didn't manage to nd one. And there was a pretty healthy chance that he just…outright bit the bullet in the chaos to come.

  To say that he was anxious, from the moment he'd woken up, to all throughout the day, was an understatement. It felt like he'd been sleepwalking through someone elses' life, distracted, as he tried to piece together as much as he could about his life before.

  He knew that he was a guy. Tobio could remember the broad strokes of Naruto's anime, though he couldn't recall how much was filler, and how much was real. Hell, he could even draw upon a wealth of supplementary, now useless knowledge, like why Rem was in fact best girl. But the big things were conspiciously absent.

  What had been his name? Did he have a father or a mother? A brother, a sister, aunts, uncles, cousins…? It was like there was this void, this gap inside of him, where all of his love and connections had been. In the abstract, it was horrifying, even if he couldn't quite find it within himself to grow tremendously upset about it.

  Maybe it'd been a mercy from whoever was responsible for dumping him there. If he'd remembered his mother, his father, his connections, being stuck here would have been intolerable. On the other hand…it didn't leave him much other choice than just to continue.

  To live a lie, and figure out a way to survive the next few years.

  That hollow inside of him swelled. Or maybe that was just his imagination. It didn't feel like something that he could tie to any physical location inside of his body, but something that he was aware of at all times. Like a gap, a void, just waiting for…something to happen.

  Well, whatever it was, he wished it would just happen already…

  Walking through Konohagakure was a little bit of a mindfuck.

  The part of him that was Tobio was well-used to the well-worn dirt streets, the smell of woodsmoke and food stalls, and the looming Hokage Rock over them. It was a comforting, familiar routine for the boy, at least from the memories that he could draw from. From the perspective of the other guy, though? Nothing could have been more of a shock.

  There was something decidedly jarring about the amount of anachronistic technological levels going on. Konohagakure had power lines, electricity, and televisions, but concrete roads were a bridge too far. That felt somewhat disjointed and impossible, and even stranger to his sensibilities was the total ck of vehicles.

  Oh, there was the odd cart or two, but mostly everyone was relying on their pin ol' feet to get around. Maybe that shouldn't be that surprising to him, though. Americans tended to build their cities and town broad, because they had the space, and a reliance on the infrastructure tied to cars. Expecting everyone else to do the same was a little silly.

  At the very least, his apartment building was not that far from the academy. It was only a fifteen-minute walk, even if the apartment itself was a little spartan. While the stipend provided to orphans was better than nothing, it was still modest enough for a bed, some basic changes of clothes and training supplies, and a few other odds and ends. For example, there was a boxy television sitting near the bed, with a propped up antenna, some books sitting half-open on a nearby desk, and just various scattered detritus of a retively short life spread all around.

  Locking the door behind himself, Tobio could do nothing but sit down on the edge of his bed and take a deep, long breath. It was earned, after the day of pretending to be someone that he wasn't. Also fortunate, because of what then proceeded to happen the moment he rested.

  That void inside of himself expanded, with the rustling of a thousand pages, as something flickered into his view.

  [GRIMOIRE SYSTEM ACTIVATED.][ROLLING STARTING PERKS…]?There was no voice to herald the words that appeared before him, hovering in the air. Merely the rustling of pages, and the feeling of power flooding through his body, as the metaphysical void inside of his soul began to be filled with something new. Something he'd never once seen before, his own sharp inhation of breath cutting through the quiet of the apartment.

  [STARTING PERKS SELECTED. CHOOSE ONE, AND CHOOSE WISELY, WIELDER OF THE GRIMOIRE SYSTEM.]? Mixed BloodFate/Legends - The nd of The Rising SunThe blood of beasts lies thickly in your veins, the sign of Oni-born ancestry in your family line. You might be the direct child of an Oni coupling with a human or a distant descendant, part of a family of Mixed Bloods who has awakened more of their heritage than normal. It's gifted you with enhanced physical abilities, enough to punch through brick walls or outrun light cavalry with ease. Your constitution makes most poison of little danger, particurly so when it comes to alcohol, taking vast amounts of the stuff to get tipsy. Apparently, this heritage also makes drink taste even more wonderful than normal. Your blood makes it easier to understand and get along with even full Oni and other mixed bloods, though this can be turned towards the more malicious purpose of making it easier to track and find them for a hunt. You're one of the lucky ones who does not suffer overtly from any inversion impulses, your oni blood remaining quiet even in battle and not causing violent rages.

  While it has not developed yet, the final gift of your heritage is that you have the potential to develop a unique power from your ancestor. Further increases in physical abilities, a death-resistant body, stealing heat or energy with a gnce, telekinesis, and many more abilities are all possible due to the variety of Oni that call Japan their home. In time, you'll gain access and continually strengthen one such ability, growing alongside you as your magical power and Mystery increases.

  AuraRWBYEvery living thing, from humans to Faunus and even animals, have a Soul. Only the Creatures of Grimm are soulless and as such can't make use of this power. For you though? You are now, thanks to the physics of this world, able to use your soul as a powerful tool called Aura. This has a variety of uses.

  To begin with Aura at default works as a sort of energy shield against attacks and damage. You wont suffer direct harm while its active, but you will still feel sensations like pain and heat while your Aura is up. It requires training to always subconsciously have a cloak of Aura on. It can even protect you from climate conditions, like walking through a snow storm, though particur extreme conditions will damage Aura like combat damage would.

  Aura can also be used to amplify your abilities, like your defence and strength making you essentially superhuman. IN addition to that just possessing Aura gives you a minor automatic healing, able to fix small wounds like scratches in seconds.All tools and equipment's are capable of being used as conduits for Aura, allowing a user to be capable of sending out crescent shaped energy sshes from their bde for example. Furthermore it can be used to enhance these things, allowing you to, for example, even use a loaf of bread as an effective weapon. Dust usages is also enabled by Aura.

  Those already possessing Auras may also unlock someone else's Aura. Doing so however takes a toll on the user, potentially weakening their own Aura for a while. Users with particur advanced experience in utilizing Aura may also be capable of other 'higher-tier' techniques. Examples would be to use Aura consciously as a shield, create shockwave like attacks, gain extrasensory perception and even sensing and identifying other peoples Auras.

  That being said Aura alone does not make you invincible. Continued damage or attacks far outweighing your Auras capabilities will be able to eventually break it. Using your Aura repeatedly also puts it at risk of decaying, to the point where the user can be left weakened and without Aura until they are able to rest. Aura being completely depleted is visually represented as a coloured sheen glowing along the length of a person's body or with coloured particles flying off the body, indicating that they can now be physically injured. Aura flickering means it is close to being depleted.

  Jujutsu (Base)Jujutsu KaisenIn this world, all but a few humans possess a form of spiritual energy known as cursed energy, which is produced when feeling negative emotions such as anger, fear, or grief. Most humans, however, they have no control over this energy. As such, it leaks freely from their body, causing it to congregate and coalesce into cursed spirits. There are an incredibly rare few who are born with the ability to control this cursed energy, though – people known as sorcerers.

  You are now one of these sorcerers, granting you the ability to manipute your own cursed energy. While you aren't capable of anything particurly special with this alone, there are a good number of benefits to this. For one, you are able to perceive cursed spirits and other spiritual entities with your senses, something usually impossible for non-sorcerers without specialised tools. Additionally, you're able to channel this cursed energy into your body to enhance your physical abilities to superhuman levels, with greater results coming from greater investments.

  The above are but the most basic of uses of cursed energy – for more specialized and powerful ones, you'll need cursed techniques. With this alone, you're capable of some basic barrier techniques, which let you create (often spherical) walls of cursed energy to close off an area. The most common form of this is a curtain: a rge, pitch bck sphere that prevents those outside the barrier from seeing what's happening within. Barriers can also be hardened to make entry or exit more difficult, though be aware that the more difficult it is to leave a barrier, the easier it is to enter and vice versa. In addition, you also have the capability to summon shikigami: creatures resembling cursed spirits created from your cursed energy. These require an intermediary such as a talisman to summon, tend to be rather straightforward in terms of abilities, and won't be particurly strong, though this may be changed with some practice.

  Unfortunately, aside from barriers and simple shikigami most cursed techniques are innate, and as such cannot be learned. It's also entirely possible for a sorcerer to be born without a cursed technique, and as such you will not receive one from this alone. The Cursed Technique section ter on will allow you to purchase one for yourself, though certain other, riskier methods may also allow you to obtain one.

  Perhaps unexpectedly, the amount of cursed energy a sorcerer has is also something determined at birth. By default, you have a rather good talent for jujutsu, granting you a respectable reserve of cursed energy which will replenish by itself. This is more than enough to stand on the same level as the majority of sorcerers, though there are a fair few who still dwarf you in the size of their reserves.

  It was all he could do for his eyes not to bug out at the individual options id before him. Sure, he could be under some sort of eborate genjutsu assault…if the very notion wasn't so ughable. Who would go out of their way to antagonize a cnless orphan, let alone create something this specific to franchises that he was familiar with?

  As insane as it was, Tobio had to consider that the strange text was real, that he wasn't having an extensive mental breakdown. And if it was telling the truth, that just meant that things were perhaps not as hopeless as he'd thought they were. Though it did also bring up new and terrifying possibilities, as he sat there on his bed.

  He had to think long and hard about the options that were offered. All of them were pretty good in their own right, no doubt about it. Becoming a Sorcerer was enough to provide access to an entirely new parallel power system, foreign from chakra. That was before you got into the subsystems inside of it, like barrier specialists or shikigami summoners.

  When someone took it the extremes, it had a lot of potential for keeping him alive…at least in the interim. But weirdly enough, it wasn't the choice that was calling to him as he sat and stared at the listing provided. Reluctantly, he moved on to consider something else.

  Aura was in many respects, a very solid option. No one would say that it was the most exciting choice, but it came with a suite of advantages few could gainsay. A roll on the superpower gacha, for example, could result in a Sembnce that was utterly broken. Or, very underwhelming, depending on your fortune.

  The forcefield wasn't anything to sneeze at either, with some more esoteric usages being described as avaible from practice. It was a package that was more defensively minded than the other two, but was wrong with wanting to stay alive? And, if he ever met someone he could trust with it, Aura was something he could grant to his given allies if need be.

  But it was also noticeable. The nail that stood out got hammered down, and that was true of the Hidden Vilges more than anything else. At best, he'd be assumed to have some kind of Hiden Jutsu, which wouldn't be that far from the truth. Which meant that people would either want to learn it, or foreigners would want to prevent it from proliferating.

  At worst…well, if this Grimoire System handed him out more perks, he didn't want to stand out any more than he already would by the dint of his new abilities. Not yet, anyway.

  Last was Mixed Blood, which was the perk he was the most shaky on. He was familiar with Tsukihime, and Melty Blood, wherein certain people had the bloodlines of Oni. This led to all sorts of unusual abilities inside of them, but frankly, it was another roulette spin as to what he might end up with there.

  Foundationally, the perk would grant him heightened strength and speed. The kind of broad, qualitative upgrade to his physicality that came from extensive taijutsu training, or just the natural state of most of the Cn Kids. In many ways, it was the kind of boon that was equivalent to a bloodline limit in what it would provide to him.

  And for a time, no one would probably notice too much amiss unless some of his Oni traits were truly overt. More than anything else, though, it was something that he felt himself naturally drifting toward. For what reason, he had no clue. It just felt right.

  That didn't stop him from being a little nervous as he confirmed his choice in the floating menu, though.

  When it vanished from sight, Tobio wasn't sure if anything had happened. If this had been some grand exercise in the colpse of his psyche, because this was an awful time for it to happen. But then, something inside of that void of his Self began to fill.

  It started on his skin, all pins and needles, as numbness blossomed across his flesh. Arming, to be sure, but nothing like the bone-deep aching that began to spread in his body. His teeth grit, fists balling into a white-knuckled grip, body dropping against the bed. Tremors unduted across his body, as every single cell, every single iota of his essence changed with the impntation of something new.

  Something this world had never seen before.

  But the base violence necessary for change was painful. It felt like he was being ripped apart at his core, as everything that made up him was altered in a way that hard to put into words. Mystery, injected into a world totally starved of it, as his shuddering, gasping transformation slowly began to come to a close.

  Breathing shallowly on his bed, he id there as the sensation of pins and needles began to fade. Eventually, when he'd felt like it was enough, he managed to lift himself up off of the sheets. Sweat was pstered across his body, as he took in a long breath, and stood up off of his bed.

  It was time to see what he got for all of his pain.

  Ambling over to his bathroom, there was a small mirror above the sink. Useful enough for these purposes, as he gnced back at the reflection in the mirror and inspected himself closely. And altogether…the changes weren't that noticeable.

  If anything they were decidedly subtle, unless you were spending a whole lot of time looking for them. His canines were longer, but only such an incrementally small amount, that someone would probably just assume he had Inuzuka in his lineage somewhere. Taller, if only by half an inch, which was still better than being short.

  The real difference was his body, though.

  Tobio had been about as fit as any other kid his age in the academy. But there was a difference between that and the feeling of solidity that was ever present across his entire physique. He felt powerful in a way that was hard to put into words. Still weaker than, well, a good number of the threats that y out there in the world.

  Compared to him of just a few hours ago? He would have whipped that wimp with a wet towel and stolen his lunch money.

  Marveling at his new body, he was a little distracted by marveling at the faint muscle definition when a new series of floating text boxes popped up, accompanied by the rustle of pages and a potent sense of power emanating from the words.

  [NEW QUEST: GRADUATE FROM THE ACADEMY!]

  [REWARD: 1x MINOR ERUDITION ROLL]

  [NEW QUEST: ACQUIRE A SENSEI!]

  [REWARD: 1x MINOR MIGHT ROLL]?

  It wasn't quite what he was expecting, and if he was being honest, Tobio still had quite a few questions. What the hell was the difference between Erudition and Might regarding the results of the rolls? Who was giving him missions in the first pce, and what was the criteria for it?

  "God…" He sighed, running a hand through his stiff hair. "I need a fucking drink…"

  The real question though, was what his goal was now. Training for the exam was obvious, and he probably had the skills to do…okay on it. In canon, he at least passed officially, which was more than even Naruto could say. But in this new life, Tobio didn't want to just skate on by...he wanted to excel. Which meant he had to figure out how to use his time wisely.
