Pilot Chapter: I'm the Demon Lord!?
[Playthrough 1: Demon Lord's Castle]
Kang Han Soo, a young man of Korean origin with messy black hair wearing a black, lightly armored, fantasy outfit, felt joy in his heart as he looked at his dead 'comrades'. He was originally an ordinary school boy from Earth, forcefully brought into this new crazy, insane, and savage world of Fantasia. The world had broken him both utterly and thoroughly in mind and spirit, twisting what once a normal teenager into an egotistically sociopath. Ten years of abuse, both by his party and their inconsiderate - it no outright abusive - actions, had led him to this point. To ambush the people he considered his tormentors and slaughtered them without mercy.
They had it coming, any sane person could see that, surely.
Good god how he missed Earth. Anime, manga, video games, and most importantly of all… Flushable toilets! But he'd have that back, after ten years of struggle he'd finally have that back.
Past the large imposing doors in front of him was the Demon Lord. He just needed to kill the final obstacle and he'd finally be able to go home after so long!
Han Soo kicked in the door revealing the form of the Demon Lord along with two other figures. One was an impossibly beautiful woman of elven origin, the Elf Queen, who was pouring the Demon King a glass of wine. The other was a young man of elven origin, a blonde pretty boy in traditional elven warrior garbs brandishing the legendary blade Endymion; this was Nasus, eldest son of the Elf Queen and crown prince of the elves.
In the center sitting on a lavishly demonic throne was the Demon Lord. Purple Skin, long white hair, twelve feet tall and built like a brick shit house. The aura of sheer power surrounding him made it known that this was the real deal.
Han Soo smirked. "You must be the Demon Lord, Pedonar."
The moment the words left his mouth, the room felt cold. Both the Elf Queen and Nasus winced.
The Demon Lord took a deep breath. "Alright, you couldn't have known this, but I loathe that name. Never call me that again. You may refer to me as Samael…"
Han Soo blinked, but shrugged. Nothing but the last wishes of a soon to be dead man, might as well grant them. He was kind like that, a model hero.
"Then you must know that I'm the Hero?"
The now named Samael looked at Han Soo unimpressed. "I know that you're late."
Han Soo was taken aback, that wasn't the response he was expecting. "What?"
"Do you have any idea how many 'Heroes' I've fought and beaten over the years?" He asked rhetorically. "Fucking countless of them." He took a long sip of his wine. "And you're the first moron to make me wait ten goddamn years, most of them get here in around three to four years. I was ready for you by year two."
Oi. this insensitive ass running his mouth as he pleases… The Bastard has no idea what he had to go through the past ten years with his insane party members!
"But I supposed it doesn't matter anymore. Better late than never as they say." Samael said dismissively, before glancing at the two at his sides. "Beloved, son, leave us. This will be over soon."
Nasus nodded, his mother following close behind, but not before kissing Samael on the cheek, getting the Demon Lord to blush slightly.
Samael cleared his throat. "Are you ready for the final battle, Hero?"
Han Soo cleared his head, focusing only on his goal: To kill this jackass and return to his civilized world. "Of course! You're my ticket out of this mad house of a world!"
Samael grinned. "I see. With eyes like those, you must be incredibly determined to kill me. Good, that's very good." Purple demonic energy began radiating off of him in waves. He stood up, downing the rest of his wine. "But do you still believe that you can match me?"
Han Soo narrowed his eyes. "Before we start, I have one question."
Samael raised an eyebrow, but shrugged. "Shoot away."
"Why did you merely stand by as I slaughtered your subordinates the last ten years?" He asked. "You could've easily killed me years ago if you took proper action."
Samael stood there staring at Han Soo for a few seconds before grinning maniacally. "Because I want you to be strong!"
Han Soo expected him to say many things… this was not one of them. "What?"
"Idiot, why would I crush you so early. What fun would that be for me?"
"But they were your subordinates!?"
"They were replaceable pawns. Do you have any idea how long I've lived? I'm an expert at building armies, you twat." He scoffed. "A little hypocritical considering how you just murdered your own party members, but hey, I'm the Demon Lord, I can't judge."
Well, he had him there. "So you wanted me to be strong?"
"Yes, I wanted you to get as strong as you could before you got here."
"Why?"
"Because I know you hero types. When your power gets rolling, you get a big head. So, I let you increase your power steadily throughout the years, to make you shoot for the stars… so kicking you back into the dirt will be all the sweeter for me." He explained. "So what if you've killed my armies and captured my territories. Being the Demon Lord… I will conquer this world again and again. This is my game, this is my world. Why wouldn't I try to spice things up a bit?"
"Well, shit..." Han Soo couldn't say he didn't get what he asked for.
He unsheathed the Holy Sword as he walked towards Samael.
"Oh?" Samael smirked. "You're approaching me?" Han Soo stopped dead in his tracks, trying to see if he heard that right. "Instead of running away, you're coming right at me? You have no armies at your disposal, no party to fight with, yet you're rushing towards death like a student scrambling to finish the problems on an exam at the last moments before the bell rings?"
Han Soo stared. He just looked at Samael for nearly a minute, trying to comprehend what he just heard. "Was... that a JoJo's reference?"
Samael's grin widened. "Bitch, it might be!" He tossed his empty wine glass onto the ground, shattering it. "But enough talk, have at you!"
"W-Wait, hold on!" Han Soo yelled. "That was Castlevania-"
Samael raised his hand, a pulse of magical energy shook the very world beneath them. "I can assure you, Hero, that you aren't ready for these hands." He suddenly disappeared, then Han Soo heard a voice behind him. "Nothing personnel, kid."
Han Soo's eyes widened, and barely drew his Holy Sword in time to block the massive blade that was about to bisect him. "Oh god, he knows memes too…!"
He felt his knees buckle under the force.
Han Soo knew that the Demon Lord wouldn't exactly be an easy time, but nothing could have prepared him for this level of absolute fuckery. The Demon Lord, the Hero's greatest sponsor, the man that allowed him to get as strong as he was now out of boredom.
"Shit!" Han Soo pushed the oversized blade back. "I really do hate plot twists like this!"
"Preach it to the choir, Hero." Samael said as he stalked forward, a manic grin on his face. "It's time to get dunked on!"
The Hero and the Demon Lord rushed each other with a thirst for blood clear in each other's eyes.
One hour, three phases, and a hidden super mode later…
The defeated Demon Lord lay before Han Soo gasping for breath as his blood pooled around him. Samael had various deep cuts all over his body, missing his legs and even one of his eyes were slashed out. Han Soo himself wasn't doing so hot either; his left arm was cut off, and covered in so many burns and cuts that he looked like he walked out of a flaming wood chipper.
"Not… bad… Hero..." Samael congratulated as he lay dying.
"Jesus Christ, you're still alive after all that!?" Han Soo yelled, using his sword as a cane to keep himself standing.
"No… you win..." He coughed up some blood. "It was fun."
"Tell me, how did you know all of those references? Are you from Earth!?"
Samael smirked, blood dripping down his mouth. "You didn't honestly... think you were the only one... summoned to this world, did you?" His body started turning into black mist. "I am… Samael, the Demon Lord… reincarnated… into this world…"
And like that, the Demon Lord of Fantasia died, turning into mist. The Demon Lord, a fellow reincarnation summoned into this world given the goal of killing heroes. It did explain why the demons had access to far more advanced technology than humanity in this world, they even had actual modern toilets!
What a tragic existence…
Oh well! Time to go home!
A few seconds later, a mysterious female figure appeared before him asking him if he enjoyed his adventure.
...And gave him a report card based on his journey.
"WHAT DO YOU MEAN I FAILED!?"
[Playthrough 2: Demon Lord's Castle]
I, Samael the Demon Lord - insert Giorno's theme here - gasped as I woke up in my throne. I blinked as I looked at my surroundings, the throne room looked exactly as it did when I was first reincarnated ten years ago, the very moment when Han Soo was summoned to this world from Earth.
I, Samael the Demon Lord - insert Giorno's theme here again - am from a version of Earth where this world is a web novel and webtoon. FFF-Class Trashero, a webtoon about the little psychotic isekai manlet that could.
Now I, Samael, have had the clock turned back on me. Ten years worth of rigorous training, planning, and scientific advancement in this shitty bootleg RPG world… all of it gone. But unlike Han Soo who was undoubtedly salty as fuck about that, I was felt excitement. Not because I have a chance to redo things, but because phase one of my ultimate plan had finally come into fruition!
My soul and the soul of the former Demon Lord, Pedonar, fused together. Our personalities affected each other and we even gained each other's memories. In mere moments my former self and the Pedonar ceased to exist. My wife murdered. My misguided daughter betrayed us, then she was betrayed herself. My original escape plan, foiled by the bastard First Hero. The new goddess who was created by my daughter, named after my deceased wife, and was essentially my granddaughter; she was enslaved, being forced even now to do the bidding over the people I loathe.
Parmael, the First Angel, and her group of interdimensional kidnappers, the Teaching Staff… I would rip them apart. Piece by piece, right before that whore's eyes. The look on that angel bitch's face when I ruin everything she's worked for.
...And the lynch pin to my master plan was Han Soo. In months time, he'd do exactly as I needed him to. All in order to rush and kill me in order to get the Teaching Staff's stupid test over with and go home. He was my unwitting minion and he wouldn't figure that out until it was too late.
"Welcome to Plan Z, Parmael, it's lemon scented!" An insane grin slowly spread across my face. "HAHAHAHAHAHAHAHAHAHAHAHA-!"
"M-My lord." One of my minions approached me fearfully. "We… We have brought the Elf Queen."
Huh?" I blinked.
Oh yeah, we captured the Elf Queen, Fiora.
I smiled. "Time to cuck that racist Elf King again."
Chapter End
So, what did you think?
This is a fanfiction of FFF-Class Trashero, a parody web novel/webtoon of isekai that is absolutely fucking nuts and I knew I could go even further beyond. Give the source material a shot if you want a laugh or two.
