On AO3 they said this Story had a super overpowered Izuku, and in some cases resembles the Ainz Ooal Gown character from Overlord.
For me, it's just fun, an I expect that someone likes (as here), others don't.
The first non-canon Dark Schneider's magic spells, like Metallica and Sepultura, are also premiered here.
So far, the story will begin to diverge from My Hero Academia story canon, and since some arcs maintains the same name, the actual contents will change, and the main enemy arc will be final part and more akin to the Hellsing or Bastard story.
The news spoiled after the USJ incident was a little delicate and embarrassing to the Yuuei's Staff Board, prompting them to stay on low profile in order to avoid sensitive leakage.
Wild rumours about a School Hero Lecture ending with a military invasion by a Nazi rogue army floats the Internet, or a student capable to wipe out scores of villains and even weapons or helicopters, spreads like a wildfire.
The official Yuuei stance was to minimize the information, or control damage, while promotes the next yearly Yuuei Sports Festival to overcome or divert the media frenzy.
Katsuki visit a gamer's vampire house!
After the USJ incident, the classes was suspended for the rest of week, given time to Izuku trains his physical body, and recovers from the huge strain that his body suffered. And since he need to rest at regular times, he shift some of own time schedule to play video-games, before alternating to physical training. Magic training was suspended during that period, for much Inko's relief.
Even recovering and relaxing at home, where his mother goes to shopping, Izuku could hear the door bell ringing, and since it was during the daytime, it becomes a little nervous, since it is rare to someone go to his home, "A neighbour?", while thinks, "Much of them already knows that is a vampire house, so they avoid them at all costs...", but runs to the door, "I'm coming..."
Izuku opens the door, and becomes astonished, "Kacchan ?!", and says, "Why are you here ?!"
"Damn, Deku...", Katsuki snarls, "I'm live just a couple blocks away, and I just wanted to visit you..."
"OK… Go on...", Izuku answers, and grabs Katsuki to the living hall.
Katsuki notices that the house was always with the window blinds closed, or exceptionally open at some house division, as long they don't stay on that division. The living hall had a television with a custom-made Steam Machine plugged in, and some print-outs of games manuals placed on the table furniture, including the games from the Assassin's Creed franchise, or the Witcher series was placed here, along some handwritten notes that Izuku writes.
"Tsck...", murmurs the blond, "I don't want to be cynical, even those games are a little underage to you, but you like playing stealth and assassination games ?!"
"Even on eve of the Yuuei Entrance Exam, I play a lot of Assassin's Creed I, II, III, Odyssey, Unity and other chapters in order to think the best way to destroy the robots...", but Katsuki blushes with some bewilderment, "How ?!...", while Izuku also blushes due to his own embarrassment, and says, "Since it won't worded at all... I ended like the Witcher, instead... I could assassinate the robots by a hidden blade...", and Izuku coughs by surprise, "Excuse me… Destroy a robot using a Witcher Sign… And ends with a requiescat in pace ... Damn it...".
Izuku was a little confused with the thoughts, and sentences, "Never mind... It's embarrassing that wizards are great literates..."
Katsuki could see that his vampire friend was a genuine computer gamer, while feel a little relief to witness a nice living room without bloody painting.
Izuku then go to his room while brings his friend, since Katsuki only visit his room about ten years ago, and could see a more gore furniture, "WTF is this ?!".
Katsuki saw various posters ranging from All Might, to vampires, like the Alucard from Hellsing franchise, to some game posters, where the main theme was demons, sorcerers, warlocks or insane vampires. The main desk was filled with books, sheets of papers, notebooks, and some skulls serving as paperweights.
The blond was about to speak when notices some old leathered books. The most recent but also leathered book that highlights had a nice handwritten title which says, "Midoriya Izuku Grimoire", where the blond reacts, "This is your spell book ?!"
"Oh, you notice it, Kacchan...", says Izuku softy while bites Katsuki neck, "It's my secret..."
Katsuki flinched by the sudden bite, and blood sucking, but manage to react, "Deku… Not again!"
Izuku runs to the bathroom to bring a some gaze and band-aids, while Katsuki notices that Izuku's bed is a normal one, for much relief. However, the genuine curiosity from the human blonde don't avoid for him search along every corner of Izuku's room, just to discovers a coffin placed above the wardrobe…
"Hwaaaaahhhh!", Katsuki screams, "Why you have a coffin ?!"
Izuku place the band-aid on Katsuki's neck before answers, "Oh! It is just for the Halloween pranks with my mom, and some close relatives, both vampires, while I have some human friends..."
"What a bad taste...", Katsuki became a little dizzy when imagine the green-hair vampire raising from the coffin with a maniac cold laugh. It still had several months before Halloween, and a real vampire could reveal an huge problem !
"Another bite, Kacchan ?!", Izuku prepares for another bite, with their fangs all elongated.
"Deku… Of course not!", Katsuki reacts by punching with their explosive quirk activated, while Izuku manage to counter using only his own physical force.
A few minutes later, once the fighting ends, Katsuki returns to the entrance hall while give an educated goodbye to Izuku, before leaving the apartment house.
School returns!
Once the week classes suspension ends, Aizawa makes a waited pronouncement, "On the next month, the Yuuei Sports Festival begins!"
Everyone cheers, "Banzai!", while even Izuku drops his fangs just by is own good mood.
"Now it is time for quirk training!", just for everyone falls flat, "This is the Heroic Department, not the Public Education Department Staff Office!"
Few minutes later, on the Gym Training Field, Aizawa acts like an angry instructor, by treating both his students as some recruits in some military training, "We will begin with an endurance 10 km run, later some cold-down exercises… And the last one, or the left behind… I will drink his blood!", leaving everyone, but Izuku who just fell annoyed, scared.
"I will call the police!", said someone, "Then… I will bite you!", and Aizawa punish Koda, Sato and Mineta by drinking about a cup of blood each one.
"And… Both of you…listen!", and Aizawa enrages, "My 100-years grandmother can finish this race in 30 minutes! I want you to make this by half!"
Everyone blames Aizawa, "Your grandmother is at least human ?! This is world record for a quirkless young adult human!"
"I don't care, so move it, move it, move it!", Aizawa flashes his red eyes to disable their quirks at the first 400 meters lap.
And the 10 km long run begins, where only Todoroki, Izuku, Yayoizoru and Bakugou manage to finish at time, while others has left behind.
Later it was an hellish round of 100 push-ups, 100 sit-ups, 100 squats, just to be a race between Izuku and Todoroki and Bakugou. The others almost fainted, specially the dwarf Mineta, who barely pass the fourth lap.
Mineta tries to recover, once the endurance race ends when the first ones cross the finish line. The grape head boy was too exhausted to continues further exercises, "Aizawa… mercy…"
"Too bad...", Aizawa even bites Mineta and drinks a little blood, "You're out...", just to drink more blood, "Sero, leave Mineta to the Recovery Girl...", while also bites and drinks a lot of Sero blood, "And you are also out..."
Only three manage to survive the exercise, Todoroki, Katsuki and Izuku, and Aizawa continues, "Then… Let's make a 100 km run, where quirks can be used freely, following by 1000 push-ups, 1000 sit-ups and 1000 squats!", and fixes it, "Once the first one finishes, the whole exercise ends... So... Move it!..."
The three boys minds turns blank when ears the next exercise, but managed to start the race. Izuku finishes the race in about 72 minutes, while the other two already fainted at the same time, even much earlier.
The teacher grabs the two boys, and bites them. Once done, and sent behind Izuku, who already drinks some water delivered by Aizawa, without facing enraged against the older vampire.
Aizawa says, "Look at them! So much quirk fancy-talking, and fails miserably by a simple exercise to be achievable by a super-human power!", while bites and drinks a little more of both Todoroki and Katsuki blood, "But Midoriya… Make the other exercises!"
And Izuku takes almost two hours to finishes the exercises, while speak, "Mercy! I'm really thirsty! ".
At such stage, Aizawa breaks a little as notices that cross some moral red lines, and to ease his cruelty, spoke, "Fine… Bite me..."
Without hesitation, Izuku bite and drinks a lot of blood, that makes Aizawa dizzy and pushes Izuku's head to force him to unhook his fangs, "Ehhh! Midoriya-kun! Please… release me!..."
Izuku snaps and release his fangs, just to realize how hungry it was, "Damn it, Aizawa-sensei...", and recovers his breath, "Did you ever think, that you push too much ?!", and almost yells, "They are humans, while I and you are vampires!..."
"I don't care… Midoriya...", and Aizawa yells, "And more 1000 push-ups, just for you!"
Midoriya latest test was make a little faster, due to the recent blood meal, ignoring the other colleges that was astonished and enraged due to the Aizawa ruthlessness, "Aizawa...", said Todoroki once recovered from the Recovery Girl infirmary, "Where's your head when you plan those exercises ?!"
Aizawa didn't answer, just count Midoriya's push-ups, "978… 979… 980..."
"Is Deku a commando soldier, or what ?!", Katsuki notices the strong, but alarming falling stamina from his vampire friend.
And finally the push-ups was over, "1000 push-ups done!", says Midoriya, when faints due to exhaustion.
"Go shower! The class is over!", Aizawa answer and the lack of empathy makes everyone enraged, where even Izuku agrees.
"What's insane...", hidden from a corner, All Might witness the whole brutal training, "If you want to break the entire class just to test Midoriya stamina, all last you had an answer...", while notices some men with military uniform pass some Intel to Aizawa himself, " The SDF was scouting Midoriya ?", All Might refer the Self Defense Forces, the Japanese Military, "It's better not to spy too much..."
Izuku's Magic Training...
During the entire month, Izuku lectures with Sakura-sensei was progressing at own pace.
"And I make this and that suggestions on the spell formula, to complete the flow circle.", says the Magical Arts teacher, "And now using this pile of garbage, practice the new own created spell, derived for the Dark Schneider's powers."
Izuku meditates and casts the chant formula, "Leather! Lou! Ozzy!", and create a darkness energetic ball, coated by a silver colour, "Breaking the Forbidden Seal of Cerberus…", where the ball size grows, while the Izuku's arms opens and tries to align to the ball, "The path for Absolute Punishment are Unleashed!", even it was separated by a safe distance of about 30 meters, "Cast the Burning Hailstorm from the Forbidden Level of Underworld...", and release the ball with a swift movement from the right brace, "Release the Ultimate Plague!…Hellish Metal Hailstorm...", and explodes the garbage by a rain of melted metal, flames and diffuses a toxic and corrosive smog, "METTALICA!"
About 10 tonnes of trash simply melted and reduced to the basic elements, where the heavy metals simply melted and form a glowing pit that slowly cools.
"Now I just bring a tonne of liquid wast sealed by metallic containers, and I want to cast this strange ice spell", request Sakura-sensei.
"An ice spell from Dark Schneider's Grimoire ?!", Izuku dumbfounds, "I mainly cast the ice version of the Magical Arrows so far, that was based on ice element vitality...", since all ice spells on Dark Schneider's Grimpoire are apocryphal.
"I know, like you, that your affinity with ice is weaker that fire, but you should try it!"
Meanwhile, driven by own curiosity, Todoroki and Katsuki arrive on the Special Training Field, where by permission of Aizawa and Sakura, they could assist the Izuku's today training.
"What, an ice spell ?!", Todoroki breaks the silence, "But Izuku's affinity is not very high!"
"Todoroki-kun have a ice type quirk, may be some jealously...", grins Izuku.
"What kind of ice spell will be ?!", asks Katsuki.
Izuku concentrates, and starts to unfold from the space behind him, a strong magnetic field, while chants, "Lors! Healy! Grey! Scole! Billy! May your soul purify me...", and the space contained by the magnetic field start to freeze, "Hell King! In this powerful gathering of sovereign beings, I will bear the destructive ice storms.", then a ice vortex forms inside the magnetic field,"Let a new link unite me to the forces of snow and ice!", ending with the enclosure of the vortex to the target, freezing and blasting almost instantaneously, "Absolute Zero Annihilation!... TESTAMENT!"
The blast also had a strong recoil, provoking severe frostbite and ice burns on Izuku body, "Damn it! The thermal shock was huge, how cold was the ice vortex maintained inside ?"
"One a moment...", Sakura checks own sensors, "Your spell creates a kind of magnetic trap, where it also used to make ultra-cold freezing…", and the computer gives the answer, "Below 0.1 Kelvin! Almost the Absolute Zero!"
"This means...", Todoroki intervenes.
"What's a great success, but...", says Sakura.
Sakura display from the laptop screen, some results generated from the magic spells experiments, and also from Aizawa brutal training, "Finally… I could compute your level of magic domain, how force you can handle, and other things...", and display briefly, "Taking your pure physical strength, you are about 25 times stronger that an average Pro Hero, that's why you could handle the brutal endurance race, but even so, you suffer some muscular strain."
"Nuts!", Katsuki remarks almost giggling, "For me, it's just 10 times or less… Until I reach him!"
"And your magic powers top capacity had energy equivalent to the original Hiroshima Bomb, where it place by the military standards as a Dragon class weapon. However your magic powers have several limits, and I split your techniques by different degrees..."
"Very well, this could make the magic management much more effective", Izuku recalls the problems when use overpowered spells, and the timings could cause an huge problem afterwards.
"First, magic like the Magic Arrows, or the Witcher Signs, are a Class-C spells, where the requirements are low, and can be cast without great problems. Your vitality, or mana, regenerates quickly after a normal daily use..."
"But not all Witcher Signs can be casted so easily..."
"The main exception, is when you cast the enhanced versions of Witcher Signs, and enter on Class-B spells. Some spells derived from Dark Schneider's powers, like the Voivod are also a Class-B spell."
"The Voivod and the Damned are casted almost without great meditation, on chanting...", Katsuki remembers when during the last lunch break, Izuku share his own hand-made Grimoire to read it.
"That's called Class-B spells, and much of them can be cast just by saying the same, once Izuku matures..."
"Why those spells requires this chants."
"It's a trick to the caster meditates and synchronize the vitality flows with his body, and generate the phenomenon called magic...", Sakura gives a brief explanation.
"The majority of spells, like the two you just witness, that require a more delicate preparation, are the Class-A spells. Normally, Izuku can only cast the same Class-A spell a few times per day, or worst their magic energy reserves could only handle about 15 to 25 Class-A spells."
"This means, without vitality...", asks Todoroki.
"No magic...", answers Sakura.
"And finally, some special spells, like the Judas Priest, Black Sabbath or Halloween, are Class-S spells, due to the high requirements, require a Ritual to create a Spell Material, or had cool-downs ranging from one week, to one month. A Ritual can aid to cast two Class-S spells, like you manage to do on USJ incident, but if you not reduce the power, as you do almost instinctively, the cool-down could slip to two or three months. And when a sorcerer are needed to use his best technique, the enemy will not wait 3 months to strike..."
"However, during the recovery of the Black Sabbath cast, I could make magic..."
"And also, not forget that your vitality was below the normal during the cool-down, even as low as 5% of the initial values, as your body prioritizes the full magic regeneration… It may be enough to Class-C or Class-B spells, but about less than 30% of their ideal powers."
"And even there's room for cheating...", Izuku refers to some alchemical potions, and similar stuff.
" It's much better to avoid mismanagement. There's why, after the Sports Festival, it will the next great topic to cover."
And after these great warning, the special lecture finishes, and both boys returns to their homes.
The Yuuei's Sports Festival begins!...
Several days later, the long awaited Yuuei Sports Festival begins, and was the first time on three possible participations, that Izuku could display his powers, while knowing, even recently, that the SDF was tailing him. For Izuku, the perspective to do the First Hero Internship on the Japanese Military was a very real possibility, since they would recruit him to do special missions on special untouchable villains that normal Heroes cannot afford at all.
Once Izuku and the rest of his classmates arrives on the installations, the entire Yuuei Colosseum was filled with thousand of spectators, ranging from Pro Heroes, normal citizens, students from other Hero Academias, and even disguised villains.
The Present Mic makes a welcoming announcement, "Everyone, listen! Today's the First Years Sports Student Competition!", and all Yuuei first-years classes arrive and pose on the field, "Give a welcome applause for the 1-A Hero Course class!", while some of mass media quickly associates them to the USJ incident.
Present Mic resumes, "But not forget the 1-B Hero class!… And also The General Course Classes, Hero Support Classes and Business Classes!"
The infamous Heroine Midnight, due to the provocative clothing, hosts the entire festival management, and also serves the role of the Master of Ceremonies.
Once Todoroki, Katsuki and Izuku gave their speeches, the first game begins, "The Obstacle Course."
The race begins right inside the stadium, and follows by about half kilometer along one access tunnel to outside, along the Yuuei grounds. Izuku runs at small velocity, just not to freighting the students, or given too much attention. After all, Izuku decided to not use signature spells too harshly, or the likes such as Magical Overboard, that could simply step in and slide along the entire course without moving a muscle. Izuku thinks that would be morally unacceptable.
Izuku's chain of troughs was dispelled when Todoroki casts an ice wall, and also freezes the ground, just before the 40 meters high wall. Since Izuku was behind from some colleges from others Courses, the vampire couldn't avoid to freeze his legs. However, a second later, Izuku casts a Igni pyrokinetic Sign to blast the ice, and jumps straight over the top wall with a Heliotrope shield spell blast. Since the entire race was broadcast over the entire Japan, and also displayed on the Coliseum TV screens, many guests faces becomes awed and perplexed by the sudden release of an apparently quirk effect.
Izuku lands safely to the ground, using several tricks, including a quintuple mortal back flip, and an Aard telekinetic blast just to reduce speed. Many of the athletes was aware of the strange Izuku own feats. Many of Izuku's mates, and the rival 1-B class thinks that Izuku was indigenously step behind by purpose, just to not give too much attention. A bit behind him, Shinsou thinks, "This guy could easily blast to the first place, if can do, why it is still hold back ?!"
Then, at the first left corner, a plaza filled with three giant robots, like the 0-point from Entrance Exams, plus a swarm of the same 1-point, 2-point and 3-point robots runs and tries to slam the students. Todoroki and Katsuki already freeze or destroy some of them. Izuku, even at about 100 meters from the front line, decide to attack, "The Great Impaler of Slush Marshes, I summon you to honour your Faithful Pact!", and a swarm of heavy rocky stalactites erupts from the ground, as the magic energy flows from Izuku body to the ground, and impales directly to several robots, "DRASH GUN!", destroying them.
"WTF ?!", Todoroki jumps backwards, "It's Izuku's new spell ?!", and Katsuki grins, "What an idiot! He shouldn't give too much attention!"
Izuku jumps straight to the front, but during the flight, he choose to cast the same spell that's done on Entrance Exam, "Deep Doomsday!... Spirits from the Air and Earth, I summon you to honour the ancient pact!... May the Earth and Sky explode to fulfil your duty on me!" , and blast one 0-point robot into a cloud of scrap metal, "MEGADEATH!"
Present Mic was astonished, like it was during the cited exam, and also the entire audience displays a strange sense of frightening, "What kind of quirk that young green-hair boy have ?!"
Meanwhile, the second big robot was destroyed by Todoroki and Katsuki, and the third one was consumed by another Izuku's spell, "Nailbomb! Calavera! Nuclear Blast!", where Izuku's first opens his braces and legs, and flows his magic directly to the ground, "May the Styx River filled with hatred and revenge, blast the corrupts to Eternal Damnation!", and blasts thousands of death rays capable to melt, burn and destroy the robot, collapsing to the ground, "SEPULTURA!"
Endeavor, who was watching his own son, Todoroki, notices the strange quirk that green-hair boy have, "WTF is going on ?! First he cast a telekinesis quirk, then some air blast, and now fire ?!"
Izuku snaps from his demeanor, and runs at the maximum speed it could handle, and arrives at the Trap Valley, filled with burning pits, some ropes, lightly toxic gases and other unspecified traps.
"Why my inner ego wants to display my Dark Schneider's powers to everyone ?!", and it's a guilty thought that was difficult to handle, "Even I use my own modified spell from Dark Schneider's Grimoire to destroy the last robot..."
Aizawa decides to speak a good excuse, "Well… If you notice well, this young and oddly boy with fluffy green hair...", and changes his voice tone to match an angry father, when their son makes embarrassing mistakes, "Have a peculiar quirk called Vryko-Warlock", and display on screen the quirk name with seven Chinese characters, 恶魔巫师吸血鬼, and the phonetic Japanese katakana transcription, ブライコウォーロック, on top of it.
Present Mic had a bad feeling, "Nice quirk name, but why have the kanjis for demon, sorcerer and vampire ?!"
"Well! Our school accepted him, since it's strong, and are one of them ...", and drops his fangs.
Then every Top Heroes, Endeavor included, understand, it was that same freak on Entrance Exam, "So, it's the famous vampire..."
"And the quirk effects are...", Aizawa grins, since it was no quirk at all, "He can cast demon-level black magic spells!... Hwahahahaha!", but became embarrassed, "Tch… Oops!"
"Basically, you just spill all, without wanting, idiot!", Endeavor grins.
Meanwhile, Todoroki runs along the ropes, to avoid the pits and trenches filled with some weird goo. But at a certain point, the heat and moisture becomes the ropes too sloppy to run above them, so everyone should holds his braces and legs around the rope, and slide around it.
Bakugou passes easily the ropes and that obstacle, using his Explosions to propel itself, while Izuku simply run or jumps the gap easily. During this period, Todoroki lose balance and falls, and then Izuku quickly casts a Magical Overboard to catch Todoroki, and brings to the nearest safe place.
"I don't believe that you make a mistake!", said Izuku to Todoroki, "Thanks!...", while the dual ice and fire quirk boy witness the awareness and subtle shock from all athletes when read the last video-clip of the curse, that was about the Izuku's quirk…
Once the top three boys reaches the last stretch of the race, they faced an entire mine field. Other racers was also just on the corner. Katsuki already races and blasts the mines before take any step.
Izuku then decides to make an huge firestorm, "Ancient Darkness Spirits from Heaven and Earth! I Pledge and Gather you!...", and prepare a hailstorm of Elemental Magic Arrows, "Gather 600 Darkness Elemental Spirits, 300 Fire Elemental Spirits, 100 Lightning Elemental Spirits...", and fires from his left hand, "Magical Spirit Crossbow Infantry Arrows!… Release!"
The storm of arrows blasts the entire mine field and propels Katsuki to mid-air. Todoroki freezes the clean field, and slides to boost speed, but Izuku simply makes a 200 km/h sprint until he reaches the entrance tunnel to the finish line.
Katsuki still recovers from the blast, but manage to get the second place, overlapping Todoroki on the last second. Izuku wons the race, but without a strange million eyes sharp looks.
"The winner is… Izuku Midoriya...", Midnight announces the winner, while thinks, "His quirk is called Vryko-Warlock ?!", and also processes the strange powers, "But why a quirk gives a plethora of techniques, ranging from energy blasts, fire explosions, or even… make a strange disc capable to catch a person and bring to him ?!"
But along the spectators, the SDF scouts already made his decisive move, "So it's him!", and points to his college, "Lieutenant... Call the Yuuei Director Staff… I want this boy to my military unit, during their so-called Heroic Internship!"
"Yes, Sir!", the young military brass salutes and walks away to the requested destination.
To be Continued...
