Full Summary:

Bakugou's life is thrown for a loop when a trio of shinobi infiltrates his school as his new classmates. As Bakugou gets to know them, he discovers that they travel across dimensions in an effort to give everyone they meet a happy ending. Originally summoned by his homeroom teacher in an effort to change a terrible future seen in a dream. Upon discovering their true identities and mission, Bakugou helps them with their plan to save his classmates from an unknown enemy. If Bakugou wants to be a true hero, he needs to not only get stronger in ways he never considered, but will also need to become a great leader as well. Protecting his class from certain doom should be a good start. If Deku is destined to be this world's greatest hero, Bakugou will aim even higher, and train to be the greatest hero of multiple worlds with the help of his new friends Kyo, Tohru and Tsubasa.

The world of Boku no Hero Academia rested peacefully for the night. The last of the civilians, pro-heroes and heroes-in-training turning in for a long-awaited rest after the UA's Cultural Festival. All was well-in this world, at least. The world adjacent to it, however, was in the midst of eternal war, plagued by death and overrun with gigantic Titans with a taste for human flesh. In another universe, two golden-haired brothers traveled the country to restore their original bodies through the power of a tiny crimson stone. In yet another, an idealistic high school student wrote the names of criminals in an accursed notebook while he dramatically ate potato chips.

These worlds-and countless others-continued to exist alongside one another, for the most part, utterly oblivious to the plights of others adjacent to them. Only a selected few were aware of the existence of these other universes,' and even fewer could do anything with this knowledge. Those aware had most likely seen it in a dream. For the World of Dreams was one everyone visited in their sleep, even if most were oblivious of this fact.

It was from this shared reality that a compelling ability was created. The power to use dreams to see future events, possibly even the ability to visit other beings through shared dreams, if their wills proved to be strong enough. A power commonly known across various dimensions as Dream-Walking.

An ability born from a desperate need to change an undesirable fate, such was the case of one underground hero. While other heroes of his world sometimes developed another form of latent power to predict disaster, known as the Hero Sense, this hero's dormant ability was one from a long-forgotten bloodline.

Aizawa P. O. V.

Aizawa Shouta didn't understand the weird sixth sense ability some heroes had when it came to predicting disasters. The fidgety intensity which rolled off of Bakugou, Midoriya and All Might right before catastrophe struck was something he learned to watch out for in them, but knew he'd never be able to emulate. Aizawa's eyes were his power, so he tended to trust their ability to assess the situation above random gut feelings. Besides, he inherited his own personal way of predicting future events.

As a kid, Aizawa grew up hearing stories of how his family had once possessed prophetic eye abilities before quirks were discovered. This ability eventually diluting within his family over time as quirks became commonplace; until it became nothing more than the occasional vivid dream and instances of dèjá vu. It wasn't much, but it was something, at least. And with his beloved class becoming the targets of more and more villain attacks, Aizawa would gladly take any advantage he could get if it meant protecting them.

When the shaggy-haired teacher found himself in the familiar black nothingness which indicated he was about to experience another prophetic dream, he prepared himself. Ready to take in every last detail in with the hope he could remember any potentially essential pieces of information given to him.

This ominous void comprised mostly of dark empty space, though murky clouds slowly shifted overhead and along the ground. Images would be displayed within their depths in confusing fragments, making them distorted at crucial moments. Different scenes played in each dream cloud, reminiscent of an old film, forcing Aizawa to divide his attention between them all.

Noises had a habit of continually fluctuating within the space. While paying close attention to one dream, a sudden commotion from another would rip the pro-hero's attention away from the scene, or voices from one dream would fade out mid-sentence. Regardless, the underground hero trudged on. Walking through the void as dream clouds displayed short scenes all around him.

The floor matched the rest of the space, making it difficult to determine where the floor ended, and the sky started. Often giving the underground hero the sensation of falling despite his bare feet being firmly planted on the ground. The marble-like floor smooth and cool to the touch.

He casually adjusted his capture weapon on his shoulders. Aizawa had always appeared in this space in the clothes he had fallen asleep in, but for some reason, his capture weapon and goggles always accompanied him here as well. Aizawa smirked fondly as he reminisced about his first trip here. It had been a few days before he started his first year at UA. He had dreamt of meeting a loud-mouthed kid with sunglasses, and the other had been him creating his signature weapon and goggles.

Despite its dark appearance, Aizawa admitted this place never felt menacing. He couldn't explain it, but the shaggy-haired man felt the space itself welcomed the company. He assumed most people were unable to see this space for what it truly was. Instead, they were confined to one of their many dream clouds. Living through its pleasant nonsense until waking, as he did when he didn't exist in this dimension.

Ignorance was bliss, after all.

The raven-haired instructor halted in front of a wall of more significant clouds. Looking up at them humbly. If Aizawa managed to get enough sleep-i.e., he wasn't woken up because two students were caught fighting in the middle of the night- and he kept a steady pace through the minor clouds along the way. The underground hero would be treated with a chance to see more influential events on these massive clouds.

After the first villain attack, he had attempted to ignore the smaller clouds in an arrogant attempt to skip to what he perceived to be the most important dreams. That proved to be a colossal mistake. Aizawa had been rewarded with nothing. Absolutely nothing. The void's clouds had slowly dissipated until none were left. However, as the last cloud disappeared into nothing, a blood-curdling scream rang out that made him sick to his stomach.

It had been Midoriya.

After months of sleepless, dreamless nights, he would relive that gut-wrenching scream the night of Bakugou's kidnapping.

The dreams graciously continued after that. With their return, Aizawa vowed that he would no longer take his powers for granted. He made an effort to take better care of himself. Made sure he got at least one night of good sleep a week, took extra care to pay attention to everything given to him, and took steps to allow certain events to happen as they were shown.

As an instructor, Aizawa did not want his students involved in the rescue of Eri. Rightfully thinking it would be too dangerous. But after a dream showcased what would happen if they didn't tag along, he begrudgingly changed his mind. Even went so far as to convince the rest of the heroes involved to let them join the rescue team, though he had never been able to disclose precisely why he needed them to be involved. It had cost him a few favors, a couple burned bridges and a promise to never speak badly to the press again to accomplish that feat. But it was well worth it in the end. Now he was the adoptive father of the cutest little girl in the world.

The shaggy-haired man patiently waited for the towering wall of clouds to come to life with premonitions of what was in store for his class. So far, the images he'd witnessed were the usual class shenanigans. Aoyama's pants falling down during training, Sato angry someone had stolen a tray of cupcakes he was making for the dorm movie night, the girls singing karaoke for their monthly "Girl's night." Iida angrily chopping the air after someone used Kirishima's hair dye to color his hair purple and, of course, the self-named, "Bakusquad," getting detention. Most likely from the said prank. Though Kirishima looked close to tears, so he would make a note that he was probably not responsible for it. Aizawa should thank his lucky stars if his only worry was whether or not Kirishima was wrongfully punished for a prank he didn't commit.

A flash of light, reminiscent of lighting, announced the beginning of another dream. Aizawa crossed his arms in preparation for what this next series of scenes would reveal to him. As always, the images started slowly at first before steadily increasing their momentum.

Images, sounds, and sensations were going through his mind at blinding speeds. Most flying by too fast for him to make sense of. The premonitions confusing and muddling his mind to the point it physically hurt. The cheerful images of the previous visions morphed into terrible darker images before his eyes. The old injuries below his eyes aching with renewed pain as he continued to watch the scenes unfold before him in absolute horror.

Through the chaos, Aizawa was able to discern Class-A's usual laughter transform into terrified screams. Watched helplessly as quirks went haywire or failed to activate altogether. Most notably, walls of ice struggling to form, only for them to shatter with the softest touch, Darkshadow raging out of control and attacking other classmates against his will. Kaminari unable to switch off his quirk and electrocuting himself, Mina facing off with a shadowy figure, her face terrified when her quirk refused to activate. Then there was Deku yelling as he faced off with a faceless villain. His body broken-the newfound control he acquired nowhere in sight.

It was too much.

The images, the screams, and the uncontrollable fear the underground hero felt from them, as clear as if they were his own emotions. It was all too much for him to handle. Aizawa couldn't take it anymore. Couldn't even look away from the carnage, for the visions played all around him. Each more painful than the last. Too distracted by the pain in his own heart to notice the world around him started to crack at his feet.

As if to further inflict pain, the misty images began to piece together, to create a more imposing spectacle. Displayed within it were the cold glowing eyes of a nomu accompanied by a shadowy figure. Both of which looked down at his terrified students who continued to fight for their lives, with sick fascination. There was also Kirishima's usually bright smile, now reduced to a pained grimace as he laid broken and bleeding heavily at a villain's feet. The villain in question preparing to aim a blow at his victim's vulnerable form.

Before he made contact, the image shifted to Bakugou, furiously blowing through the chaos to get to his friend. Only to be taken by surprise by a sudden explosion. The aggravated yell Bakugou let out when he was swallowed up by flames, soon shifted into a pained scream, which was suddenly cut off short. The resulting inferno began to bleed into the rest of the dreams until only the death screams of the rest of his class could be heard.

The eraser hero wasn't exactly sure when he had fallen to his knees. But there he was, crouched on the ground as his world burned all around him. His dark tired eyes stared blankly at the blaze in front of him. Not daring to look at the ground in case he saw the burning corpse of one of his students.

"No...," Aizawa whispered hoarsely. His throat was raw as if he had been in the fire as well. He tightened his grip on his capture weapon instinctively, his body involuntarily shaking in-not fear, but unfiltered rage.

"No!" Aizawa snarled, pushing himself to his feet. Eyes subconsciously flaring red, which caused the fissures at his feet cracked even further.

"So that's it?! That's what we get after dedicating our lives to protect people? We get to train, develop, and then lead the next generation of heroes to their deaths?!" Aizawa yelled to the void in unrestrained anger. Abandoning all reason or cares about how ridiculous he probably looked yelling at no one in particular. A small part of him realized how much he resembled Bakugou at this moment, though the rest of him didn't care. In fact, he felt like he understood his explosive student a little better now. Taking this to heart, he continued to yell all of his frustrations into the nothingness around him in a rare instance of vulnerability.

Aizawa was enraged.

Infuriated that with all the quirks and resources UA and the professional heroes had to offer, they still couldn't manage to keep one class of future heroes out of harm's way! Angry a month couldn't go by without a villain attack, villain encounter, serious injury, or gods forbid a group of his students doing vigilante work behind his back. Frustrated, that despite all the progress, his ragtag group of students worked so hard to accomplish, it would all be for nothing if fate had anything to say about.

"Screw you, Fate..." Aizawa finished, winded from his uncharacteristic tirade. His throat was so raw he could taste blood in the back of his throat. But that hardly mattered. The underground hero swore to himself that he would find a way to protect his class. Aizawa would not let these events transpire the way they were shown. That he would fight any villain thrown his way. Even prepared to sacrifice himself if that was what it took to keep them all safe.

A boisterous crack rang through the void. Breaking Aizawa out of his thoughts. Looking down, he finally noticed the fissures under his feet had spread out all over. The once sturdy ground, now on the brink of collapsing. Some shards had already fallen into the dark abyss below. His glowing eyes studied the ground for a moment before blinking. The shaggy raven hair immediately falling to rest gently on his shoulders. The slight movement was all that was needed to create the last crack, which forcibly plunged Aizawa into the depths below.

Present Mic. had once told Aizawa if you fell in your sleep, you would wake up. He was wrong. The shaggy-haired man fell through the floor and would have crashed hard into the water below had he not used his capture weapon to slow his fall by grabbing a still attached piece of...ceiling?

The fragment broke off immediately, but it slowed him down enough to only twist his ankle slightly upon landing. An injury that would no doubt transfer to his physical body once the hero woke up. He made a mental note to make Present Mic. pay for this later.

The sound of falling water took his attention away from the pain in his ankle. Around him were various small waterfalls that seemed to emit a vibrant blue sparkly light of their own. His eyes traced up their length in curiosity, but they eventually disappeared from view. Oddly, they seemed to start higher than where he had fallen. Looking down, he discovered his bare feet effortlessly balanced on the glowing water's surface, which constantly rippled from the numerous waterfalls. However, when he placed a hand on the water's surface, he discovered that he could actually reach within its depths if he wished to.

Dream clouds from his own dream world slowly started drifting into this new area. As they descended, their forms gradually transformed from dark hazy clouds to white fluffy ones and eventually turned to ice when it came into contact with one of the waterfalls. Creating entrancing frozen mirrors in its place.

The once gloomy images displayed inside them changed and became more explicit, thanks to its new form. Aizawa's initial thought was that the scenes were simply repeating themselves since he saw quirks were still going haywire. However, on closer inspection, he realized the outcomes were changing.

A wall of struggling ice flashed towards an enemy. It shatters with ease, just like before, only this time waiting behind the obstruction of view was Todoroki and Uraraka. Taking the villain by surprise, they quickly take them down and restrain them with a long chain. Another scene depicted Kaminari, Mina, and even Sero taking on enemies with an assortment of weapons instead of relying on their quirks. Accompanying these revised visions were numerous scenes of the rest of his class defending themselves without their quirks, with a precision and expertise in martial arts and weaponry skills that amazed even Aizawa. Some of his students actually seemed to be enjoying themselves despite the threat of certain death looming over them.

Kirishima's broken and bloody form transformed into him, flashing a familiar shark-toothed grin as he stood side by side with a girl Aizawa didn't recognize. She had bright sapphire eyes and long brown hair with long dangly blue ribbons tied on either side of her head. Both were scuffed up a bit, but their eyes shined with determination as they held their weapons toward an unseen enemy.

Another scene showed Bakugou back to back with another kid he didn't recognize. This kid had bright orange hair and mischievous red eyes. They both had clearly been through the wringer, their clothes scorched and tattered beyond salvation. Regardless, they still maintained matching determined-if not a little psychotic-expressions on their faces as they taunted their foes, kunai in hands.

Everything suddenly stopped. Not just the scenes shown within the frozen mirrors, but the ever-shifting tendrils of the misty clouds and waterfalls as well. Making this new void so painfully silent and unnerving.

Sensing another presence, Aizawa immediately twirled around. Casting his capture weapon at one of the nearby waterfalls, activating his eraser quirk as he did so. The carbon fiber weapon managed to catch something just out of sight within the water. A sword suddenly broke through the cascade a second later. Halting just short of his throat.

Aizawa let out an annoyed tsk. His glowing eyes peering through the fall for any sign of movement.

The scuffle had expelled most of the frozen-in-time water to reveal a teenager with short light brown hair wielding twin swords. Despite feeling the icy cold of steel against his throat, Aizawa couldn't help but feel more unnerved by how his attacker appeared to be the same age as his students. The teen was dressed in a black tank top, white cargo pants, black combat boots, and gloves, a beaten pair of silver goggles hung around his neck with a worn dark green cloak completing his ensemble.

Tension in Aizawa's hand stole his attention. Following the length of his scarf, he discovered his weapon struggling to secure one of the teenager's wrists to his other sword. Twisting the child's arm in such a manner the underground hero assumed was an uncomfortable position for him. However, no pain reflected in the youths' cold brown eyes as he too assessed the situation he suddenly found himself in.

"I don't want to hurt you. But I will if you don't leave here now," the brunette ordered, using the point of one of his swords to lift Aizawa's chin threateningly. His unique accent took the hero by surprise. Sounding both foreign, yet vaguely familiar at the same time. The flash of recognition did not go unnoticed by the sword wielder. "Who are you?" he asked puzzled.

In a show of good faith, the shaggy-haired man slackened his weapon a few degrees before answering, "My name is Shota Aizawa," the hero answered truthfully. His stance still guarded and on high alert. Aizawa's sharp eyes didn't miss the way the kid seemed to breathe a little easier once the tension on his wrist was gone. Noting the subtle rotating movement, he tried to hide as he assessed the damage done. "I came here by mistake. I'm not entirely sure what this place is either."

The teen's eyes casually drifted to the hovering images around them. Observing how they not only transformed but also became clearer upon mixing with his own dreams. Amber eyes lingered on the visions directly behind Aizawa for a moment before the teen slowly relaxed out of his stance.

"I believe we've gotten off on the wrong foot," he announced, withdrawing the blade from Aizawa's exposed neck until it rested at his side. "My name is Tsubasa."

The underground hero blinked, allowing his glowing red eyes to fade back to their standard charcoal color. Feeling a little better now that the blade no longer rested against his throat, but he kept his loose hold on Tsubasa. Years of hero experience unwilling to let him give up his only advantage under these questionable circumstances. He also didn't miss how Tsubasa had failed to provide his surname.

"Where are you from?" he asked in an attempt to extract more information about the brunette's intentions. "I've heard your accent before. You're not from Japan?" Aizawa determined but wasn't positive.

"I am not," the brunette admitted hesitantly. Choosing his words with care. His light brown eyes regarding the man before him thoughtfully before continuing. "I am from the Land of Fire, though my accent is from my mother's tribe, which no longer exists. My brothers and I being the last of this bloodline."

"Land of Fire? Where is that?" Aizawa asked, puzzled. He might not look like it, but the scruffy hero had been a model student when he attended UA. Excelling in all subjects, especially International Hero Politics. "That's not a real place," the underground hero argued, his eyes narrowing in renewed suspicion. The captured weapon was beginning to tighten around his target once more.

The teen maintained eye contact with the suspicious hero before him. "It might not exist in your world, but I can assure you, it is a real place," Tsubasa tried to explain, gesturing with his hand before the movement was restricted again. The teen frowned at the wraps around his wrist.

"I understand your apprehension, but you have nothing to fear from me," The teen assured, tugging slightly at his restraints. "I believe you broke through my dream for a reason." Tsubasa determined, using his free sword to point at the images behind his captor.

"What do you mean?" Aizawa asked warily, risking a brief glance behind him.

"Allow me to show you," Tsubasa responded, his once brown eyes now glowing a silvery blue.

Movement on the water covered floor caught Aizawa's attention. The water's reflection revealed Tsubasa with magnificent eagle wings on his back. However, his real body remained as it was. Before Aizawa could comment on it, Tsubasa pointed toward a few of the small waterfalls around them with his free sword. They immediately began to widen and merge to create a towering wall of falling water before them. A few places iced over from the combination of both their dreams colliding, like smudges on a screen, that Tsubasa was unable to bend to his will.

"These were the dreams I was experiencing before you broke through. They didn't make any sense until I saw the remnants of yours." Tsubasa explained as new images began to play.

Never had Aizawa experienced dreams as clearly as he did when he gazed up at the scenes reflected in the massive wall of water. Projected on a surface easily as large as a screen from a movie theater, with only some distortion from the moving water. The first scene was of Tsubasa and the two other teens Aizawa recognized from his previous dreams. They were wearing UA uniforms and chatted happily with his students in the cafeteria. This scene changed to the trio teaching the future heroes hand to hand combat as well as weaponry skills. The water rippled to reveal another scene of Tsubasa, this time speaking with a boy with spiky purple hair and tired eyes which rivaled Aizawa's own. Immediately recognizing him as Shinso. Aizawa had just enough time to wonder how he fitted into all this before the image changed to Kirishima and the brunette sparring in the gyms after hours. Both sporting smiles that rivaled the sun.

The last scene was of two explosive boys with red eyes sparring with explosions as well as weapons. The gigantic waterfall could barely keep up with their speed and intensity. It struggled to contain the force of their explosions. Each one shooting water in all directions, soaking both spectators in the process. With a final boom, the dream shattered as the waterfall itself exploded, sending water everywhere. The sound of chaotic laughter echoing alongside the water raining down around them.

Tsubasa turned to Aizawa. His eyes ominous eyes flickering back to their standard color, along with his perplexing reflection. "As you can see, it appears my group is intended to help you guys out," he explained, wobbling on his feet slightly. Resting a hand on his sword, which was planted firmly in the water, to stable himself. "You weren't in any of my dreams, so I didn't make the connection at first."

"How did you do that?" Aizawa asked in a mixture of astonishment and suspicion. He had never been one to easily put his trust in others. Especially after seeing disturbing images of his students getting slaughtered before his very eyes. Having a stranger suddenly appear, promising to save his students from certain death was just too convenient to be a mere coincidence. However, a small part of him longed for it to be true. His eyes studied the teen still in his grasp for a few moments before Aizawa continued to prod him for information, "How do I know these images were really depicting future events and weren't an illusion you created with your Quirk?"

"Quirk?" the sword wielder repeated, his head cocking to one side in confusion. His free hand absently scratched the back of his head as he tried to figure out what his captor meant.

Troubled amber eyes stared into suspicious charcoal ones.

"I don't know what you mean by 'Quirk,' but the images you saw were real. Just as real as yours," he assured after awhile. Realizing the man in front of him didn't look convinced, Tsubasa continued. "Besides, no matter how strong one's dream abilities are, they cannot be used to fool another Dream Walker."

It was Aizawa's turn to be confused. "What is a Dream Walker?"

Tsubasa smiled at his inquiry. "I see you still have a lot to learn about your powers, the World-of-Dreams, and the infinite number of worlds beyond your own," the teen determined, motioning to the space around them. Using his sword to point to the faint outline of the hole, Aizawa fell through. "When you broke through your dream world in the hope of changing fate through sheer will power alone, you Aizawa Shouta became a Dream Walker," Tsubasa explained matter of fact.

"Other worlds? You keep saying that, but that's not..." Aizawa began, before a memory long forgotten resurfaced.

The underground hero vaguely remembered a girl-a young woman-with long dark brown hair, wolf ears, and a tail; rescue him from villains when he was a kid. How her eyes glowed a silvery blue when she fought. She had been doing vigilante work, which, of course, was illegal at the time. Though laws had never stopped her from saving people. Aizawa recalled her saying how she never understood how this world was so hung up on rules and regulations when it came to helping people in need. He remembered the way she disappeared in a show of colorful lights so dazzling and surreal, Aizawa had dismissed it as a dream. Her voice so warm and friendly, with an accent he had never experienced again. That was until today.

Curious amber orbs watched Aizawa closely.

"The idea that other worlds exist outside of your own might be difficult to believe, but it is true. My family has been traveling between worlds for generations, and we've still only visited a small number of them."

"Your family?" Aizawa repeated. Once again, recalling the wolf-eared woman from his past. That would explain the similarities. "When I was a child, I met a woman with wolf ears and tail who claimed to be from another world. Was she a family member of yours?"

A flash of sadness reflected in the teen's brown eyes before they were quickly replaced with their usual warmth. "That would be my mother, Amaya," Tsubasa replied quietly. "She died when I was little."

Aizawa didn't need to press him for any sort of explanation. The sadness that briefly ran across his features told him everything. She had died on the job. It was a look the teacher had seen on many pro-heroes faces over the years. An expression that could never be faked no matter how gifted someone was at deception.

Pushing the thought aside, he continued, "You expect me to believe you travel to different worlds to help strangers out of the goodness of your hearts?"

Tsubasa smirked at that. "Do we need any other reason to help those in need?"

The underground hero smiled at the familiar naive words despite himself. He looked back at his dream clouds, which did appear to be unaffected by Tsubasa's powers. They still displayed glimmers of a hopeful future. The fellow Dream Walker seemed to be telling the truth when he said his powers were unable to affect the contents of his dreams. Only able to provide clarity to them within this space. It would be a considerable gamble to trust him and accept his help to teach his students to protect themselves without their quirks. However, refusing would be certain death.

Aizawa looked back at the teen, expecting him to be studying him carefully as he always did, but was surprised to see him staring at one of the hero's dream clouds instead. It was the one of Bakugou back to back with one of Tsubasa's teammates. Honestly, of all the images, this one surprised Aizawa the most. He figured only Kirishima and the self-proclaimed Bakusquad could ever get that close to Bakugou without risking their lives. But against all the odds, there stood a kid who couldn't have known Bakugou for more than a few months. Fighting side by side with one of his most volatile students in perfect harmony. Not only that, but the mysterious teen managed to get him to use a weapon instead of using his treasured quirk.

Bakugou, not use his quirk?! What a feat! Mr. I-Hate-Everything-Quirkless was not using his quirk-willingly?

Aizawa took a closer look at the weapon in the explosive teen's hand. It was a three-pronged kunai.

Oh. That was why.

The underground hero looked back at Tsubasa. Noticing for the first time, the heartache within his gentle amber eyes. The twin three-pronged kunai in their hands had been Amaya's prized weapons. He remembered them clearly when she had rescued him as a kid and the time they had spent together up to her departing from his world. Thinking back on it, that must have been the image that was displayed behind him when Tsubasa decided to lower his sword.

Such a treasured weapon wouldn't be handed over lightly. No wonder Tsubasa decided to trust me so easily, Aizawa mused to himself. The least he could do was show him the same courtesy. He owed it to his mother.

The Underground hero turned to face the teen before him. Nimble fingers pulling at on his own treasured weapon, freeing Tsubasa from its tense grip. The sudden release broke the brunette out of his thoughts. Aizawa then calmly kneeled, resting an arm on his knee as he does so.

"I, Aizawa Shouta, the Eraser Hero of Musutafu, Japan, hereby implore the services of Tsubasa and company, to save my students from the catastrophe I saw in a dream. Please travel to my world and teach them all to fight without the use of their quirks so they might be spared such a gruesome fate," Aizawa enlisted to the son of his savior.

Tsubasa blinked cutely, shuffling slightly in embarrassment by the sudden formality he received. A smile steadily graced his features when he found the strength to compose himself. With a determined expression, his amber eyes once again glowed a dazzling silvery blue.

A firm hand gently came to rest on one of the kneeling hero's shoulders.

"Before an agreement can be made, please allow me to explain a few things," Tsubasa expressed as magical power began to swell around him with the forming of a contract of services.

A nod from the Aizawa urged the Dream Walker to continue with, "Even if we come to your world to help. There is no guarantee that the terrible events depicted in your dreams won't come to pass. You must understand that it is entirely possible that after all our best efforts, some or all of us will still die," Tsubasa warned in a severe tone.

The Dream Walker went on to explain how complicated and possibly dangerous changing fate could end up being. How each person that learned of future events would risk thwarting their preferred outcome since people tended to second-guess their choices. Thus inadvertently creating infinite new possible futures for them to navigate through, each one worse than the one before it.

"Would you still like to put your trust in us?" Tsubasa finally asked when he was done with his explanation.

Determined charcoal eyes meet amber ones.

"Yes," Aizawa answered without hesitation. The pro-hero knew the risks. Understood that he could still be leading his class to utter ruin, but that didn't matter. Aizawa had already promised himself he would do anything to save his students. Accepting these strangers' help would no doubt bring their own consequences, but as long as those repercussions didn't result in death, he would gladly bear them. "Even so, if there is even a glimmer of hope to save them, I will take that chance. So, I implore you to do everything in your power to help me change their fate."

Tsubasa smiled at the man's declaration. He offered a hand to the man kneeling before him. "Then I, Tsubasa Hitsuzen, hereby accept your request on behalf of my teammates. We shall travel to your world and do everything in our power to aid you in your time of need. We offer you our knowledge, our weapons, and powers to you until your quest is fulfilled," Tsubasa vowed, gently pulling Aizawa to his feet. "My family is honored to serve your family once again."

Aizawa and Tsubasa spend the rest of their dream sharing information and creating a plan to save everyone. Once the young dream walker woke in a far off universe, he informed his teammates of their next mission. Hastily making preparations to rendezvous with Aizawa in his world within a week.

As they planned, Aizawa couldn't help but be reminded of Tsubasa's mother when he looked at him. They not only looked similar but acted the same as well. He was reminded again that while this trio of shinobi would be here to help them, they were only kids themselves. The same age as his class as it turned out. Aizawa would be sure to protect them from the trials awaiting them as well. He wouldn't let any of them become a casualty. The next few months were bound to be interesting, to say the least.

I've wanted to write this story for a while now. Even from the first season I could see the similarities between the My Hero Academia characters and the alternate versions of the characters I created. Especially with Bakugou and Kirishima. In the next few chapters I'm sure you'll also see some of the similarities with their powers and personalities. I've also seen some similarities with where the manga. I'm a little annoyed that some of my ideas for this story has already come up in the manga because I wasn't fast enough with my writing. I'll be sure to make a note when I get to a certain chapter about these instances. Anyways, I hope you enjoy this story.
