Hizashi Yamada vs. the dragon flight
Chapter one: Hizashi, Hizashi, by his honor is sworn
Hizashi walked into a classroom to do his job as a teacher at UA for a change one well enough day over at UA High School. Walking into the classroom, Hizashi saw all of Aizawa's students waiting for him. "Good morning my wonderful students," Hizashi greeted. Getting to the teacher's desk at the front of the classroom, Hizashi went on, "Is there anything that any of you think we ought to talk about before we start class?"
"Yeah, that Saiyan girl you adopted as a daughter ate all of the food we had in our dorm building's kitchen area," Bakugo said, a dry look on his face, as he raised a hand.
"And then she beat all of us in video games," Kaminari spoke up.
"And then she smacked Mineta in the face so hard after he patted her butt," Ojiro said, "That it sent him flying through the one window on the ground floor in the main area, before she fired energy attacks from her hands that flew after and blasted into Mineta. The girls in class don't exactly mind what happened to Mineta, though."
Holding up his hands at shoulder level with the palms facing forward, Hizashi said, "Hol' up a minute there class." With all eyes on him, Hizashi said, "Mineta slapped Veggie's butt?"
"You... aren't going to ask about her feat of great physical strength or the fact she can conjure and cast energy attacks?" Sato asked, "Because that's pretty pertinent right now if you think about it. I mean I know she's an alien thus she doesn't have a quirk, but she's got a few powers anyway."
"Yeah, all Saiyans have a pool of various powers Sato," Hizashi replied, "It's nothing to worry about." Looking around, Hizashi asked, "Where is Mineta btw?"
Jerking her thumb at Mineta's desk, in which sat Inosuke who was fast asleep and snoring away, Yaoyorozu said, "Mineta's still in the ICU because of the beating he got. Hense why one of the Demon Slayers that you're friends with is asleep at Mineta's desk, Yamada-sensei."
Sighing, Hizashi said, "Yeah, Inosuke had a rough night last night. He as well as Tanjiro and Zenitsu had to calm Nezuko down after she drank what she thought was juice but was actually a bottle of fine red wine that Nemuri was saving. Hoo boy, let me tell you kids that Red Wine Drunk Nezuko can solo the final boss enemy of the manga no problem."
"Which..." Izuku began, looking confused, "...Which manga are you talking about, Yamada-sensei?"
"Every manga under the rainbow," Hizashi replied, "And also Harry Potter."
"Didn't Harry Potter cast a spell that twisted your nuts that one time?" Mina asked as she raised a hand.
Pointing at Mina, Hizashi asked, "You were still dead when that happened. Who told you?"
Pointing to the sleeping Inosuke, Mina replied, "He did."
Hizashi let out a sigh before he said, "Well that's just great. I was hoping that-"
Hizashi was cut off when Aizawa came barreling into the room in a clear case of panic. Following him were Tanjiro, Zenitsu, Nezuko, and GulusGammamon. "Hizashi!" Aizawa exclaimed, "There's an extreme major emergency going on right now! Classes have been canceled for the rest of the day so that we can deal with it!"
As the class cheered which woke Inosuke up, Hizashi said, "Not that having the rest of the day off is a bother to me, but I gotta ask. What the hell happened, Sho?"
"Remember how it had been brought up that the now long dead All For One had been working on a secret contingency plan to deal with the covent of vampires that were led by Asui's mom before she was wished back to life as a living breathing human?" GulusGammamon began.
"Yeah, me, my dad, and my little brother are glad both mom and my little sister were also returned to life by the multi-rez wish kero," Tsuyu said.
GulusGammamon was about to continue, but he was cut off when Toshinori and Veggie came into the classroom. "Veggie, my sweet little princess!" Hizashi said upon seeing his adopted alien daughter, "No need to worry! Daddy will find the little pervert who smacked your butt and strangle him with his own sphincter!"
"I'm happy to hear that you as my new human dad is protective of my maiden virtue," Veggie said, "But we ought to focus on the big winged flying reptiles in the sky."
"...Que?" Hizashi replied, looking lost and confused.
Sighing, Toshinori said, "Here's the thing, Hizashi. It turns out that All For One's contingency plan to deal with the covent of vampires was creating an army of dragons to fight the vampires."
"The fuck?" Tenya said, looking utterly surprised, "You mean to tell us All Might that we have to deal with a bunch of dragons now?" Dragging his hand down his face, Tenya said, "Shit, this is going to be a pain in the ass."
"Dudes!" Kirishima exclaimed, "Iida just cursed!"
"This series is a drug-fueled fever dream," Tenya said, "I've given up trying to be a model student here a LONG time ago."
To Aizawa and his party, Hizashi asked, "Where exactly did the dragons come from?"
"As it turned out," Aizawa began, "All For One got a DNA sample from Ryukyu somehow-"
"The fuck?!" Uraraka and Tsuyu said in unison.
Continuing, Aizawa went on, "And from it synthesized a bunch of copies of the Dragon quirk which he then gave to random people under his sway. Unfortunately, the beings who we now know are really just people with copies of Ryukyu's quirk have gone berserk for some odd reason or another."
"They're all transformed into dragons," Toshinori said, "Aizawa's Erasure quirk won't work on them for some odd reason, and if the dragons aren't stopped then Japan is gonna be fucked in the ass." Everyone could then hear a moan of aroused, sensual pleasure sound out in the distance.
Hizashi was about to speak up, but was cut off when he and everyone else heard roars coming from outside. Leading the way, Hizashi got everyone in the room to follow him outside to see how exactly bad things were right now.
In the main courtyard outside of the front of UA, Hizashi and everyone saw that the dark gray cloudy skies above were littered with dragons flying about. Many of them were roaring, with some firing off breath weapons of various emitter type quirks. "Oh shit," Nezuko said, "This dragon apocalypse will be a serious mood killer that will keep me from being able to sex Zenitsu-kun up really good later on this evening."
"NEZUKO!" Tanjiro exclaimed in a surprised, scandalous tone as Zenitsu could only chuckle a bit in amused embarrassment as he rubbed the back of his head.
As Hizashi and his group looked up at the dragon apocalypse flying about in the skies above, one of the dragons flew in and flew in place a few meters above Hizashi's group. Looking down at Hizashi, the dragon said, "Ful, losei Dovahkiin? Zu'u koraav nid nol dov do hi."
Tenya, with the driest look he's ever had on his face, scowled and said in a similarly dry tone, "Shit, this is gonna be a Skyrim parody, isn't it." The tone in which Tenya spoke made him sound more like he was making a statement he was sure of, rather than ask a question.
"The fuck did you just say, you dragon dummy?" Hizashi said, "I'll have you know that All Might had only banged Midoriya's mom once so far, back when we had to deal with the vampires!"
"I'm still not sure how to feel knowing that my idol has had sex with my mom," Izuku said in an embarrassed and unsure tone.
Scoffing, the dragon talking to Hizashi said, "You do not even know our tongue, do you? Such arrogance, to dare take for yourself the name of dovah."
"Who the hell are you?!" Inosuke shouted up at the dragon.
Turning its attention to Inosuke, the dragon said, "I am known as Wyrmscale, and I am merely one of the many dragons in service to Shakakhan the Shackle-Breaker. The age of humanity has gone to the inferno river to calmly breathe its last, as now the age of dragons shall start and reign supreme from now until the heat-death of the universe."
"You do know that none of you guys are actual dragons, right?" Aizawa said, "You all are actually humans transformed into dragons with synthesized copies of the Dragon quirk, but for some odd reason I can't turn your quirks off with Erasure."
Turning to look at Aizawa, the dragon known as Wyrmscale said, "That is because our change into dragons is permanent, we are stuck as dragons from here on out. This was a deliberate plot by he who granted us the gift of dragonic being, so as to protect us from the foul sway of the vampires he had prepped us to vanquish. But there are now no vampires anymore. We dragons are now without purpose, so we figured that we'd wipe out the humans for shits and giggles."
Throwing his hands up into the air, Toshinori said, "Fuck! All For One has ruined who knows how many innocent lives because Nezu got drunk and challenged Loki!"
Turning its attention back to Hizashi, Wyrmscale said, "If it is your aim to stop the coming of the age of dragons, then your best bet is to challenge Shakakhan the Shackle-Breaker and vanquish him in single combat. I offer you that idea, for it will do us dragons no harm in the long run. After all, what harm can a human do to a dragon?"
"I accept your challenge, Wyrmscale," Hizashi said, "As it just so happens, I have a full set of the perfect equipment for slaying dragons! Armor, sword, a shield, you name it!"
Wyrmscale chuckled in amusement at Hizashi's challenge. "Perhaps you humans may be worth a modicum of entertainment after all. Very well. To enter the lair of Shakakhan located on Skuldafn Mountain, you must first gather the three treasures and bring them to the sealed stone doors at Skuldafn Mountain. When near the doors, the treasures will glow with magical power and make the doors open themselves. Then you may enter to find and challenge Shakakhan."
Shrugging, Hizashi asked, "Where the hell is Skuldafn Mountain?" Wyrmscale then turned and pointed at a mountain that could be seen in the distance. "...That's Mt. Fuji, you ass," Hizashi pointed out dryly, able to tell that the mountain in question is really Mt. Fuji.
"It is Skuldafn Mountain now, human," Wyrmscale said, "And just to make sure you and your group will continue the plot..." Wyrmscale raised his head up and loosed a roar, summoning a number of other dragons. The dragons, including Wyrmscale, flew down and grabbed at Hizashi's group, taking the Class 1-A girls and Zenitsu as a result.
"The Lord of all Dragons awaits your challenge, human whose hair looks like a giant banana," said Wrymscale as he and the other dragons flew off with the Class 1-A girls and Zenitsu, all of whom were screaming in fright as they were being kidnapped.
"Shit!" Inosuke exclaimed, "They kidnapped a bunch of girls!"
Throwing his hands up into the air, Aizawa said, "And we just stood around like a bunch of fucking morons and let it happen!" Scowling, Aizawa exclaimed, "Just how can this get any worse?!"
At that moment, Sekijiro came running out, followed by Ryo, Nemuri, and the Class 1-B boys. "Hey, a bunch of dragons just kidnapped all of my female students," Sekijiro said, "Do any of you have any idea about all of that?"
"FUCK!" Aizawa exclaimed, a rightfully pissed off look on his face.
END, CHAPTER ONE
Author's notes;
This is the first chapter of the last story in the Hizashi Yamada series. Here, it's revealed that the now long dead All For One got a DNA sample from Ryukyu somehow, synthesized a bunch of copies of the Dragon quirk from it, and gave those Dragon quirk copies to random people under his sway in order to build an army of dragons to fight the vampires he was worried about with.
But All For One is now long dead, and there are no vampires, so now the people with the Dragon quirk copies, all permanently changed to dragons because All For One wanted to make absolutely sure they would be able to handle the vampires, are going on a rampage with the intent of wiping out humanity for shits and giggles. Also, some of the dragons have cool as balls names.
Anyway, Hizashi decided that he'll stop the age of dragons from coming and save humanity, so the dragon Wyrmscale informs him of the leader of the dragons, Shakakhan the Shackle-Breaker, as well as where to find him. The dragons also kidnap all of the Class 1-A and Class 1-B girls, and also Zenitsu, to make sure the others will keep the plot going. Keep an eye out for the next chapter.
