I am in fact not dead. I apologize for the wait for this chapter. I was having a difficult time these last few months and I did not really have the energy to write. Anyways I'm back again hopefully there won't be a uhhh- *checks notes * 3 month break between chapters this time. Anyways into the comments:

Ash Peverell: Obrigado pelo seu elogio! Fico feliz em ver as pessoas gostando da minha história. Espero que você goste de onde eu decido levar isso. Na verdade, eu não ia dar a Harry uma técnica com tema de morte originalmente, mas então li seu comentário e meus neurônios decidiram disparar e toda aquela coisa de mestre da morte voltou à minha cabeça. Não acredito que esqueci disso. Honestamente, acho que o consumo de energia é muito menor do que planejei originalmente, então obrigado por me dar a ideia! Eu acho que conta como um tema de morte se você considerar que comer almas está nessa área.

coronadomontes: Thank you - Thank you.

Guest: Hope no longer for I am here with more!

Chapter 3: Change

Albus Dumbledore - Hogwarts, England

What I would not give to live in simpler times.

mused the headmaster of Hogwarts. Ever since the deaths of Lily, James and young Harry life had only gotten harder for Albus. At first it was the grief that had consumed him. The weight of his failures pressed down on him, drowning him in the knowledge that all of the horror was partially his doing. He had after all, never stopped Tom Riddle from presuming his darker studies, content to live in his delusion that they were purely for academic purposes. He never thought the young boy would act on what he had learned. How wrong he was.

Now the consequences of his delusions had come for him. He could have let that grief consume him, but another emotion had arisen in its place.

Rage

And so he used it. Turned his burning anger into a blade, and with it he cut his way through the Death Eaters, pulling them, root and stem out of the proverbial garden until nothing but bad memories remained of them.

Some had tried to claim imperious. They had all forgotten that Albus was a master Legilimens, and nobody outside of the accused had been willing to contest the strongest wizard of their time lest he turn his suspicions onto them.

Once all the trials had concluded Albus had been content to let magical Britain rule itself again. He had been content to slink back into the shadows and act as the headmaster of Hogwarts again, to be a silent protector. Fate, it seemed, enjoyed laughing in the face of mortal desires. Not even a year had passed before a new catastrophe had reared its head. This time at least the catastrophe had worn a monster's face.

Initially sightings of these mysterious creatures had been sporadic, children whispered about a cloaked wolf-like figure haunting the shrieking shack, and rumours of a colossal misshapen dementor had spread out of Azkaban. At first these were dismissed as the ramblings of insane inmates, or stories told by children to make a dare more interesting. That was quickly proven wrong when one morning the guards awoke to find every inmate in Azkaban reduced to nothing more than a rotting soulless husk.

Afterwards all over the country sightings of these creatures increased. At first the Ministry attempted to treat them as any other magical creature, confine them away from the muggles and keep them in special reserves. That idea quickly fell apart when their designated handlers were butchered like cattle. The official Ministry stance on these newfound 'dark' creatures had swiftly changed after that. Kill on sight orders had been issued and the Auror corps had been dispatched to deal with the threat. Everyone that was sent died trying to subdue them. The situation quickly deteriorated from there, any sighting of these creatures caused mass panic amongst the wizarding world and seemingly made each and every one of them stronger.

Even more concerning, the creatures were beginning to encroach on the muggle cities, and the secrecy of the magical world was becoming an increasingly tenuous thing. If they started to rampage through the cities no amount of obliviators and secrecy campaigns would be able to save the statute. And so as much as Albus wanted to enjoy his 'retirement' from war, he was very quickly called to aid the ministry in dealing with the threat.

Who better to combat the new darkness than the one who banished the old. Mused the elder professor. He was currently in a meeting with all of his staff and while it had started off as a 'standard' meeting, the topic of discussion had quickly turned towards the new terror rampaging throughout Britain.

"Minerva, Have there been any updates on the origins of these creatures?" Asked Albus

"No headmaster, nothing in any library seems to point to where ever they came from. Even the unspeakables are stumped." Stated the stern voice of Professor McGonagall.

"I think we honestly need to consider the idea that these things aren't creatures of any form." Interjected the Defence Professor for the year, one Sirius Black. "I mean Merlin knows they don't act like any other creature in existence the more you look and treat them like a spell or even a familiar of sorts the more they seem to make sense."

"Then what do you suggest Black." Sneared the oily voice of Professor Snape. "Teach everyone to cast a non existent counter curse and everything will magically work out? I must say I knew you were an idiot but I never expected you to be an optimist."

"Well excuse me Mr. Vampire bat. I was trying to be helpful, unlike your emergency apparition potion. How is that going by the way?"

"Better than your failing excuse for a class Black. What were you teaching this week again? Ahh yes. Muggle martial arts. How useful."

"At least my-"

"Enough!" Professor Dumbledore roared. "Snape, Black. I understand the two of you have unresolved issues but that is no excuse for two colleagues to belittle each other and act like immature school children. You will both stow your rivalry for the remainder of this year, I will not have two of my professors at each other's throats while we all already have these creatures at ours. Do I make myself clear?"

"Crystal..."

"Yes professor."

"Good. Now then tempers are already high enough so let us all put aside this meeting for now we can reconvene at a later date when cooler heads will prevail. Professor Black please stay behind. I must talk to you about your tenure here."

Sirius shifted in his seat as all of his colleagues Left the room, a nervous energy settling in him. He turned towards Dumbledor mouth agape to say something but the elder headmaster spoke first.

"Calm yourself Sirius. I merely wanted to talk about the curse affecting your position, not anything you've done."

"Oh thank god. I thought for a second you were about to fire me."

"You'll have to forgive me." Dumbledore gave a slight smile as mischief showed in his eyes. "There is so much wrong in the world that I thought to emulate your younger self for a moment there."

Sirius sighed. "Those were the days. When all we had to worry about was dodging detention for our latest piece of mischief."

"Those were indeed Professor Black. I find Hogwarts so empty, so lifeless now, with everything that's happened I would almost welcome a second group of marauders. That would at least bring some life back to this dreary castle."

"Maybe it would Headmaster, Maybe it would."

Sirius leaned back in his chair staring off for a moment, eyes glazed over in a quiet reflection.

James, Lilly, I'm sorry.

Breaking out of his thoughts Sirius addressed Headmaster Dumbledore. "So what did you want to talk about professor?"

"I merely wanted to inform you I've found a way to break the curse on your position."

Sirius's eyes shot up in surprise. "Really? I didn't think it was possible."

"Well the impossible seems to be constantly staring us in the face now." Sighed Dumbledore. "One more impossibility doesn't seem too out of belief does it?"

Sirius laughed. No, one more impossible thing isn't that hard to believe now is it?

"So I get to keep the position?"

"If you want Professor Black."

"Yes, absolutely headmaster I would love to stay."

"Well then. I shall have the updated contract to you by the end of the week Professor Black."

"Wonderful." Said a now grinning Sirius. "Do you still need me or can I go? I have a test to mark for the 4th years."

"No, you may go Sirius."

Sirius made to leave. He had just stood from his chair and grabbed his coat when Albus stopped him again.

"Actually, one passing curiosity, Sirius. Why teach Muggle martial arts?"

"Oh, it's to help give the kids a chance of escaping those creatures should the worst happen. Magic doesn't work on them so I had to come up with something to help. I figured teaching them to escape getting grabbed and how to fall properly was better than nothing."

"Very well, it's sound logic. If any of the other professors or students approach you about this, do let them know to come to me with their complaints."

Sirius gave a grin. "Absolutely headmaster."

Harry Gojo - Tokyo Jujutsu High

A sigh of satisfaction escaped Harry as he surveyed the results of his training. All throughout the glade Harry was standing in the broken ruins of glass bottles, targets and training mats could be found littering the ground. With a flourish Harry sheathed his katana and turned his attention internally to the flow of his cursed energy.

Like every other time he had used his cursed energy Harry found it waiting for him, a writhing tempest of negativity lying just beneath the surface of his soul. With a thought he dismissed his control over it, letting the energy calm and settle back into its rightful place.

Harry turned to begin cleaning up the mess made by his training when he noticed an odd 'hum' in his cursed energy. Well 'hum' might be the correct description. After a few seconds of examination Harry found it to be more like a repeating pattern of intent in his cursed energy. Cautiously, Harry began investigating it, any changes in his cursed energy were something to be weary of. Usually, that meant that a binding vow had been formed but Harry had entered into no such vow. The only other thing Harry could think of that would cause the change would be a cursed technique. But that was impossible, or at least it should be. Jujutsu High's grounds were protected by Tengen's barrier, enemy sorcerers should not be able to get in. So that meant that it was purely internal. Perfect.

Harry sighed as he started to compliment what could cause a change in cursed energy. He hadn't done something so stupid as to mess with any cursed objects and his katana was (for now) not a cursed tool, so the only thing that could cause a change would be a cursed technique, an internal cursed technique.

Wait a fucking second. Does this mean that I have an innate technique?

Harry's contemplation stopped as his realization became clear. He had resigned himself to being a third rate sorcerer. With only martial skills he would have likely gotten rolled over by anything above second grade, and without a heavenly restriction to aid him all he had was his fists and his brain. But now, maybe he could be more than that. Harry's face broke out into a manic grin as he began to set up all of his training gear again. Soda cans, wooden sticks (he was out of training mats) and old glass bottles once again lined the glade.

Once Harry took a position near the center of the glade he began to poke and prod at his technique. It was different from anything he had ever sensed before. Dad's technique was well and truly limitless. And it felt like it too. An endless expanse of cursed energy that lay just beneath the surface. Other sorcerer techniques also felt somewhat distinct. Yaga's technique always felt like a tapestry of sorts, spreading outward to each of his cursed corpses. And uncle Nanamin's technique always felt rigid and divided, fitting for his ratio technique. Harry's technique felt nothing like those to him. He poked and prodded at it for a while with his cursed energy, and instead of reacting he felt nothing but silence.

Total silence.

In Harry's opinion humans were not built to be in silence. Noise ment company, it meant that there was life in the area, even if it wasn't human life, it was still life. So when Harry delved into his technique and was met with nothingness he had to suppress a shudder as the weight of the void pressed against his mind. Taking a moment to compose himself Harry began to delve deeper into his technique, trying to see if there was more to know before he tested it in reality. Harry delved into the void of his soul and was met with another feeling he did not expect. Hunger.

An endless ravenous hunger. One that hungered specifically for cursed energy.

Well that's not at all worrying. Thought Harry as he catalogued what he knew. A complete silence and a boundless hunger for cursed energy, and by proxy, souls.

"Welp. Nothing ventured, nothing gained." Harry entered a combative stance as he began to call his cursed energy again. With one final push he flooded his soul with energy, unleashed his technique and the world around him died.

Satoru Gojo - Akita Prefecture

Satoru Gojo was bored. Not that that was an uncommon state for him to be in, but he had hoped that his current mission would be a bit more interesting.

His hopes currently lay in ruins.

Around him the crushed remains of multiple curses lay scattered about the abandoned warehouse he was currently in. Gashes carved by colossal talons mared the already cracked walls and the distinct starburst patterns of explosive ash dotted the floor.

But there was not a single scratch on Satoru Gojo, none of the curses could get past limitless after all. Nobody could.

Sighing to himself, Gojo turned to the last remaining curse. A nightmarish amalgamation of a firehose, metal piping and discoloured flesh.

"Well then garden hose this has been... a fight. You tried I guess~. Well time to-"

Ding-

Gojo looked down to see a message from his son. Glancing back over at the curse he quickly used blue to immobilize it, crushing it against a wall before turning to what were obviously infinitely more important matters.

Harry (gremlin): Got my technique :). When u gonna get home? I gotta show you, it's kinda gross tho.

Well never mind this isn't just infinitely important it's infinity squared important.

Grinning to himself Gojo turned towards the curse ensuring it's immobility before using blue to teleport halfway across the country.

Space folded around Gojo as he exerted his technique. To others it would look as though he just disappeared and reappeared somewhere else as though the world was correcting an error and just popping him into existence, but for him it was different. Limitless and the six-eyes gave him a complete understanding of space and time. To Gojo he was simply creating a bridge to where he needed to be, and walked across it.

Matters of perspective aside, Gojo teleported directly into his living room, and coincidentally teleporting directly in front of his son who jumped back in obvious alarm.

"Yo gremlin. Congrats on unlocking your technique, I knew you had one!"

"God damn it dad! Don't teleport directly in front of me, you scared me."

"Oh sorry, it was an accident I promise."

An incredulous look passed over Harry's face for a moment before he sighed.

"So why are you here dad, I thought you were on a mission."

"Oh that can wait, besides those curses were super weak anyways~. So boring. Actually... we could use those guys." A manic grin appeared on Gojo's face. "Wanna try your technique out?"

The grin was quickly matched by his son's.

-{=BREAK=}-

Harry Gojo- Akita Prefecture

Among heaven and earth, I alone make this job harder for everyone else.

Harry was seriously regretting agreeing to come try his technique on a living curse. The firehose curse his dad had "captured" (read: brutalized and then incapacitated) was a semi-grade one.

Weak my ass! What the hell am I supposed to do with this!

Externally Harry tried to keep a calm exterior as he looked at the thing. It was hideous, covered in scratches and blood. It had clearly killed recently, and was trying in vain to escape the confines of blue.

Harry took a moment to process the curse before turning to his father.

"Dad."

"Yes son."

"This is a semi-grade one."

"I know. But look at it! It's so pathetic! Trying to fight is pointless for it I don't know why it even bothers~ "

"And let me guess you want me to exorcise it."

"Got it in one Harry-Kun~. Oh and before you say anything don't worry I'll be here in case things go wrong. Just have fun with it, Mr. Garden hose here is super weak after all."

I'm gonna die. I'm actually screwed, what am I supposed to do! I'm grade 3. It's a fucking semi-grade one. What am I supposed to do!

Harry was broken out of his thoughts by his dad giving him a pat on the back and then subsequently shoving him towards the curse.

"Good luck!"

Gojo then teleported halfway across the warehouse and pulled out his phone to record the coming disaster.

With a rising feeling of dread Harry unsheathed his katana as he sized up the curse. Its movement was becoming increasingly more erratic as blue's hold on it lessened. The seemingly easy prey in front of it was also only making it more bloodthirsty.

Finally with a pop, blue gave away and the curse was freed from its confinement. Harry wasted no time as he instantly rushed the thing. His katana flashed through the air, and steel met curse flesh as it carved a hose like appendage off. The firehose curse screamed in agony and began to channel its technique. Harry was able to grab the severed appendage just before the cursed finished gathering it's cursed energy and he was blasted backwards against the wall as a stream of highly pressurized water and cursed blood erupted from the severed appendage.

Groaning Harry removed himself from the crater he had created in the wall.

"Thank god for cursed reinforcement." Harry muttered as he took a stance again.

Lets see here. A water manipulation technique that uses pressurized water to attack. Effective at longer ranges where opponents without a defensive technique are weakest.

A grin spread across Harry's face as he saw the curse point its appendages at him, pressure deforming the metal pipes. Harry's stance deepend as he called up his own technique. He called upon the silent void and from his hands a dark most spread out and enveloped his katana as he entered a stance. Behind him the severed arm of the firehose curse began to rapidly decay, undergoing months of degradation in mere moments. Cursed energy flowed off the arm towards Harry's now firmly sheathed blade.

New Shadow Style: Simple Domain

The curse reared back and launched another burst of pressurized water at Harry, but this time he was ready. Simple domain guided his blade towards the water, and his technique enveloped the blade turning steel to a black void.

Too bad for you garden hose.

Harry's blade flew towards the burst of water, black mist flowing off of the edge towards the water.

My technique beats yours.

Blade and mist met water and instead of slicing through it ineffectively Harry's blade instead deleted the water wherever they met, devouring it like wildfire.

Harry ran towards the curse taking advantage of its momentary shock, slicing and consuming cursed water all the while. Distantly he heard Gojo's holler of excitement as his dad saw his technique in action. He reached the curse and taking advantage of its unfortunate blunder Harry reared back and sliced the curse clean through the 'neck'. Cursed blood and water sprayed everywhere as Harry finished his strike, the curse bursting into teal flames before its remains flew towards his sword and were sucked into the void.

With a flourish Harry sheathed his sword and turned around just in time for his dad to once again teleport right in front of him.

Grins on their faces Harry and Gojo met with a high five, before Gojo pulled Harry into a hug.

"Good job grade-one. I'm proud of you."

"Thanks dad. What do you think of my-. WAIT WHAT DO YOU MEAN GRADE ONE!"

Gojo smiled, kneeling down to make 'eye contact' with his son. "Well you handled a semi-grade one with no problems. I'd say that qualifies for a promotion."

"FUCK YESSSS!"

Laughing Gojo stood back up and looked over where his son had just exorcised the curse. The six eyes traced over the residuals from the battle or rather, the lack of residuals. Everywhere Harry had gone the cursed energy in the area had seemingly been erased from existence. Quite literally devoured by Harry's technique. Turning back to Harry, Gojo looked over his son, the six eyes showing him more than any other would have seen.

His reserves have increased. Thought Gojo. That's a special grade technique if I've ever seen one. I wonder if it could get through limitless.

"So Harry-kun~. What exactly is your technique?"

"Haven't you figured it out already dad? I mean, I'm pretty sure the six eyes just showed you."

"Yea I already know~. But I'd like to hear you say it, interpretation matters for jujutsu you know~.

Huffing to himself and muttering something foul under his breath Harry explained his technique:

"It's called Devour. I can essentially eat cursed energy and techniques from the area around that black mist. Though I do have to pump more energy into my technique than my opponent did to theirs for it to actually work."

"So that's a no on limitless?"

"Yes dad. That's a no on the reality bending technique." Harry deadpanned.

"Well that's a shame~" Gojo sighed. "Still that's an amazing technique, though I recommend thinking a bit more about it, there's probably something you can do with all that cursed energy aside from just increasing your own reserves."

With a flat look on his face Harry turned to address his father "Don't you already know if there's more I can do?"

"Of course I do~! But where would be the fun in telling you everything now~! You've gotta figure this out, who knows maybe you'll do it right when all hope seems lost~. Wouldn't that make for such an epic scene!"

"This isn't a Shounen dad. The power of friendship won't save me from getting my face ripped off by an angry curse."

A now laughing Gojo just teleported the pair home, his mission, and Harry's impromptu lesson / grand debut completed.

The two spent the rest of the day testing the limits of Harry's technique. Careful applications of blue eventually lead to a father son game of 'dodge blue' before Harry exhausted his reserves and the two went in for dinner laughing all the while.

Neither of them noticed a crow breach the tree line fly off towards Tokyo.

Alrighty I'm so sorry this took so long to get out. Between a semester of really important prerequisite classes all of which I found challenging, writing for the conclusion to a two and a half year long dnd campaign and working 16 hours a week I couldn't really find time to write for this. Hopefully this semester will be less shitty and I'll have more time to write. A few things I wanted to note before I leave you all. I have planned out the next arc of this story. The next few chapters will be the end to the training arc, and then we get to go to England. Yay. I've also written out a timeline for everyone's convenience too.

Timeline:

2003: Harry is born.

2004: Voldemort killed Harry's parents and then gets killed by Gojo. Gojo adopts Harry.

2006: Kaori (age 5) runs from the Zen'in clan

2009: Gojo stops Megumi's sale to the Zen'in clan Megumi and Tsumiki live on their own

2015: current chapter. Sirius meets with Dumbledore as cursed spirits begin to become more of a problem in England. Harry unlocks his technique and kills the Firehose curse.

I also just wanted to say that as I've outlined the story a bit I've decided to remove the Megumi tag and replace it with Sirius. Sorry to all the Megumi fans, Mr. Potential will get his time to shine eventually but Sirius took much more of a prominent role than I had originally thought so he gets the tag instead. Speaking of, we get to see the results of a Dumbledore who wasn't willing to sit back and let an extremely flawed justice system do its "work". Harry's "death" changed him in a few ways and considering that he ended up acting as judge jury and executioner to all the death eaters in my verse I figured Sirius had no reason to end up in Azkaban since Dumbledore was looking into everyone personally, and the man is an expert legilimens (mind reader). So he's now Hogwarts permanent defence teacher. Snape is having a grand old time with that. With that I feel like I'll sign off for now. As always constructive criticism is greatly appreciated. Hope everyone has a wonderful rest of their day/night.
