'Tha' hell.' This shit sounded like AI or some shtick. "Oi! Who’s talkin’ get out ’ere!" Zanka shouted.

'Tha' fuck!' He was lying on a bed. Looking upwards at the ceiling then down, he himself was dressed in navy blue shitagi, black vest over the top and obi. but what brought him true terror was his sister who he hadn't seen in three years. Back straight, dressed in traditional garment, her hair long as it use to be in her younger years and looking at him with those eyes.

He newer wanted to see those eyes. Looking at him with disappointment.

He wanted to scream, to run. But he can't. Nijima's don't run from anything, don't cower in fear. He swallowed the bile in his mouth, and sat up.

"Onee-san?"

Notes:

What the hell you are you about to read? Do I loooook...? LISTEN! My favorite SVSSS fic and Gachi fic got updated at the same time and my high as a kit brain on painkillers decided: Wouldn't it be fun if I smushed them together? I have three exams tomorrow, and i could be doing the mature thing, but do I look like I have self control? No! so, here i am raw dogging this thing right in AO3 at 06:54 The sun isn't even up my dudes. You are working with 2 hours of sleep here, exhaustion from work and God's wrath that is week-long Primary dysmenorrhea. (if you don't know what that is. Don't Google it. As we Slavics say: The less you know the tighter you'll sleep.) God I feel like my brain is fucking me up in the corner of the alleyway with a rusty pipe to my back head.

Anyways, who needs sleep, right?

Basically Janka is Tianlang-jun/Su Xiyan kinda' thin. Oh and English isn't my first language, it's not even my fourth, so yeah. Any mistakes are between you, me and God.

Chapter Text

It's official, as of this day Zanka Nijima has upgraded himself as Gachiakuta's biggest hater. Now, he will enlighten all of you on what Gachiakuta was and why he hated it.

Gachiakuta was a dark fantasy manga series written and illustrated by the mangaka Kanaru. It felt like a brick hurled through a stained-glass window.

To be precise, Gachiakuta was a rage-fueled, trash-punk, monster-fighting battle manga packed with social inequality, weaponized garbage, grotesque creatures, and enough emotional trauma to make readers stare at the ceiling at three in the morning, questioning capitalism, fate, and their own life choices.

This generation’s peak dark-shounen tragedy—no debate.

It had a large cult following that loved to hate it, whether for the writing or the story itself. Many of that same crowd referred to it as lackluster and devoid of intrigue, claiming the characters were hard to keep track of and hardly worth remembering. The number of times someone had said nonsense like, “There’s nothing about any of the characters individually that stands out,” or, “They’re all one-dimensional, with no personality—easily forgettable,” was genuinely infuriating.

The story is set in a dystopian world where a floating, country-sized structure known as the Sphere runs on a social caste system, dividing the rich from the poor who live along the outer perimeter—people labeled “descended from notorious criminals and exiled” by the upper class. A heavily guarded wall keeps the two worlds apart. But despite that the residents of both sides carried celestial bloodline. From both sides, trash, unwanted waste, and even people convicted of crimes were hurled into a literal abyss called the “Pit.”

And at the center of this magnificent landfill of despair—gloom and doom incarnate—stood the protagonist: Rudo Surebrec. The only living descendent of God. An almighty being capable of both destruction and creation. And later on in final chapters revealed that the Sphere itself is being kept afloat by him.

Rudo himself was a teenager whom much of the fandom, be it the haters and devoted fans alike described him as an angry Pomeranian puppy.

Honestly, who wouldn’t? The little guy had anger issues the size of a megalodon and the body of a pipsqueak. But hey, the truth was uglier. The poor kid was severely malnourished despite living in the Sphere, physically abused, and eventually abandoned by his parents. Heck, even his adoptive father is killed in front of him. his heart slowly blackened after suffering many misfortunes, if they could be called that.

And let’s not even talk about his first crush… Yeah. That can of worms better stays closed at all times, because if not, Zanka was going to have an aneurysm the size of a boulder.

God knew how many hours he had spent in comment sections across every possible platform, defending that poor boy and cursing seven generations of that girl's ancestors—Chiwa was her name. Ugh! he knows it's wrong to hate a child. He does, really. But Rudo was his son, okay.

If someone had told him three years ago—back when he was still an active figure skater—that he would become this emotionally invested in absolute trash like this, he would have given them the beatdown of the century. And yet here he was, glued to the glowing screen of his PC after a long day at the office dealing with one of the most troublesome clients imaginable. But at least the last case had been one of his favorites—yakuza divorces.

The legal side was relatively simple—the husband didn’t want his dirty laundry aired out, and the wife usually doesn’t want to fuck with her soon-to-be ex-husband. A win-win situation in his books honestly.

…Wait. He’d gotten sidetracked. Where was he again?

Oh, right—his rant about how much of a trash fire Gachiakuta was.

'Why?' You ask.

Because that stupid mangaka had killed off his favorite character. That’s why.

'Just—why?'

He would never admit out loud who it was, but still—how dare they? One moment there he was he was enjoying the newest chapter, and the next—bam!

Jabbre was dead.

And the worst part?

That crazy, masochistic, bald, rotisserie-chicken-looking ass killed himself.

Who’s Jabbre, you ask?

Jabber Wonger was one of the main antagonists: violent, psychotic, fight-obsessed, and completely deranged masochist. a natural-born genius with limitless potential and endless room to grow. Exactly the kind of person Zanka should have hated the most.

So if that was true… why did he love Jabber’s character enough to curse the mangaka to hell and back?

Because of his backstory, damn it!

"Stupid mangaka, stupid manga!! I'll be seen ya' in hell!" Shouted Zanka, with whatever strength was left in him as he stared at the screen from his spot where he laid on the floor.

Never in his wildest imaginations did he think, he'd be dying from food poisoning from an expired yogurt. he should have know when it tasted bitter, guess that shit had S. aureus in it or something. Just his luck, damn it. It's not his fault he didn't feel anything amiss, he was too busy raging. Sure he had thought of ending his life a few times. When his Fractureed leg forced him to stop figure skating for example.

Such a pathetic way to go, just as pathetic as him. he's sure his body won't be found unit it starts rotting. But at least his family will be happy to be rid of such failure as Zanka.

He could feel tha' darkens consume him. Until he heard a robotic voice speaking directly in his head.

[Activation code: "Stupid mangaka, stupid manga!! I'll be seen ya' in hell!" System automatically triggered.]

'Tha' hell.' This shit sounded like AI or some shtick. "Oi! Who’s talkin’ get out ’ere!" Zanka shouted.

'Tha' fuck!' He was lying on a bed. Looking upwards at the ceiling then down, he himself was dressed in navy blue shitagi, black vest over the top and obi. but what brought him true terror was his sister who he hadn't seen in three years. Back straight, dressed in traditional garment, her hair long as it use to be in her younger years and looking at him with those eyes.

He newer wanted to see those eyes. Looking at him with disappointment.

He wanted to scream, to run. But he can't. Nijima's don't run from anything, don't cower in fear. He swallowed the bile in his mouth, and sat up.

"Onee-san?" He asked with what he hoped a nonchalant voice.

"You fell unconscious during training. you may rest today, but tomorrow I expect to see you at training." with that said she doesn't glance at him a second longer and leaves.

A breath leaves him he didn't know he was holding.

'Systems.'

Suddenly, a ‘Ding’ noise made its presence known, and the mechanical voice he heard in the void sounded again, very pleased with itself. Screaming right into his mind.

[Welcome to the System. o(≧∀≦)o]

[Binding your role: ‘Zanka Nijiku’ One of the mambers of the team akuta. the mentor to the main character Rudo Surebrec. ######## ##### lineage (Locked), ####### linkage (Locked), body memory, Weapons: Jinki: Aibo (Locked), Jinki: ####? (Locked), Katana/Staff. Starting A Points: 100 ]

'deep breath, in and out, in and out! ya can do this...' Zanks chanted in his head, trying to use every possible trick in the self-care books recommend. he needed to calm himself before he gave in to his more violent urges and broke the 3D screen that showed up in front of him.

Desperately trying to think positively, to stop himself from embracing his anger in the face of his current dilemma, he asked: “Why am I ’ere, then?”

[You initiate the command for the System’s implementation is already bound to the account ‘Zanka Nijiku’.]

“Is that so…” Zanka’s eyebrow twitched, “Go on, then… show me the rules book, the terms and conditions, all that rubbish, ’cause I reckon ya… a massive one, and I’ll happily sue ya asses for it.” the smile turned bloodthirsty and just like always the hardcore lawyer took a stand, causing the System’s screen to flash red and back away.

[...Host...Danna-sama? ∘ ∘ ∘ ( °ヮ° ) ?]

“Terms and conditions! Now!” Zanka snapped,his anger getting the best of him, causing the System to let a peep, before complying with his demands.

It showed him everything he demanded on the 3D screen, allowing him to survey and read through. “So you hauled me ’ere, expectin’ and figured I’d keep silent, yeah? Funny thing, why d’people keep pissin’ off lawyers, knowin’ they’d get screwed.” He mumbled to himself as he read everything thoroughly, ignoring the quiver screen.

[Danna—Danna-sama? (ó﹏ò。)]

“Would ya look at tha’ you’ve made quite a mess—broken dozens of rules, violated the terms and conditions, every guideline ignored. Tsk, tsk… the case I put together’ll shut your whole company down and bleed it dry. I’ll see to that personally.”

[Impossible! ¡|!(0∆0)!|¡ The System makes no mistakes!]

“Oh? But you did!” Zanka's smile was no doubt on the grotesque side as the System’s screen backed away. “Rule No. 1. Never brake a DNR. Ya’ just did.”

[but—Danna-sama is completely healthy. (ㆆ_ㆆ)]

“Oh? don't ya’ know any adult can request a DNR.”

[Error] The System’s screen started flashing red, and a screeching sound resonated all around him causing him to furrow his brows. the ‘Error’ message kept flashing over and over. Everything only calmed down after ten minutes or so, and a huge golden screen replaced the tiny blue one.

[Commencing. Main System]
[User 0002, welcome! This is the Main System speaking. We deeply apologize for the mix-up, but unfortunately, we are incapable of transport you back to your original world or body as you're already bound to the character ‘Zanka Nijiku’. Please accept our deepest apology once more. We will make sure to punish System 80085234 for their mistakes and make your stay in this world as enjoyable as it is possible with our capabilities.]

“And what exactly am I meant to do with that, after you’ve smashed half a dozen rules and hauled me into this mess? I’ll sue you till you’re yellin’ unc’ until your ‘creator’ comes runnin’ to fix yor’ nonsense—see if er’ enjoys that. ” Zanka snapped back, remembering he had read something about a ‘Creator’ whose words were law, and every violation would result in punishment worse than termination.

[Error] The screen in front of him flashed red before returning to gold.

[Main System]
[User 0002, please don't be hasty! I am sure we could reach an agreement that could satisfy both sides!]

“Oh… an agreement you said…” He grinned, knowing that he had the System in his grasp now. his every demand was gonna be offered to him on a golden platter. “Fine, give me a pen and paper and I'll write the demands.” Zanka smiled cheerfully, ignoring the shaking System.

Soon, the System received the airtight contract filled With loopholes that only he was aware of and could use to his advantage when needed. After reading the contract once more, he nodded in satisfaction, giving the contract to the System it disappeared the way it had appeared. 'How fascinating.'

[Main System]
[User 0002...]

Zanka hummed as he tilted his head in question.

[Main System]
[While the System understood the second condition of unlocking the OOC function… unlocking both of User 0002 lineages will cause a major divergence and violation of the plot…]

“Sound like a you problem, not a me problem… so you can deal with the fallout. Up to you—your ‘Creator’ actually, or we settle this nicely. I don't mind dyin’ see. Been there, done that. But you? I doubt ya can bounce back, now can ya?”

Sobbing noises could be heard from the Main System, finally admitting defeat. Ah what a lovely music to his ears. And complying with his every demand, no matter how silly or confusing it was sending a thrill down his spine.

[Main System]
[.·°՞(っ-ᯅ-ς)՞°·.] and on this beautiful day in this Trash filled world the poor Main System realized one thing that would later on be written into rulebook.

‘Lawyers are forbidden from use The System’s transmigrating services! Dishonor on you, and on your cow if you brake this rule!’ If there were a picture of Zanka as a reference beside the said rule—no one dared to mentioned it.

Notes:

yes, it is possible to die from food poisoning especially if S. aureus is involved. Yes, yogurt can be contaminate by S. aureus when produced from raw milk or handled with poor hygiene, and it takes like, what? 30 minutes for you to join your ancestors. So, be careful what you eat. and i will not explain why i know this.

Notes:

Honestly, I might delete this once I'm done with my finals, have a good sleep and reread this with a fresh set of eyes. But hey! until then enjoy! and at the very least I'm getting this idea out of my head. bye!

Edit: so, just got back from uni... I lived! And from what I'm seeing you guys want me to continue?!?!Σ( ̄□ ̄;)
