In a burst of purple smoke, a red fist came flying out. Attached to it was the arachnid hero moving in a forward motion. As the smoke cleared, he found himself falling into a forward roll, smacking his back against the wall of a building. He grunted, letting his body collapse to the concrete ground. His vision was blurred by the sudden sunlight, and his new lenses had to adjust accordingly. When they finally did, he used his left hand and pushed on the wall to bring himself to his feet. It was only now his spider-sense finally stopped ringing, and he was able to have a moment of silence.
He looked around and finally took into consideration that the scenery around him had changed. He was no longer at the S.H.I.E.L.D prison, and it was no longer nighttime. Now, he found himself in the alleyway of a city, during the middle of the day. He was shielded from the sunlight by the buildings, casting a dark shade into the alleyway. Overall though, it was clean with barely any trash on the ground.
Spider-Man put a hand to his ear, attempting to turn on the wireless communications built into the mask, "Mr. Stark? Are you there?" He spoke clearly, but he received nothing but static as a response, "Tony, come in. Its Peter, where are you?"
Still, there was nothing for him. Communications with the Avengers were down, so he couldn't expect help from them any time soon. However, what mattered now was finding out just where he ended up. He looked to the wall he crashed into earlier and started crawling up it with ease. He only needed to attach his finger tips to the wall to scale up it, showing that he had a great amount of strength in his palms. It didn't take him long to reach the top and stand where he could see the city.
It didn't look like New York, as the buildings were designed very differently. Looking down into the streets, he hoped to get a better view of where he was based off the people and stores. It became clearer when he saw the signs pestered to the stores. The language written on them he could only guess was Japanese. The people walking in and out of the stores we're mostly Asian as well. Was he in Japan? How did he get all the way out here?
But then it was obvious; When his fist collided with The Green Goblin, he had the space stone. That stone allows for travel to anywhere in the Universe. Why he ended up in Japan was a real mystery, but supposedly it could have been random.
Then another thought crossed his mind.

'Goblin,' He thought, 'If I'm here in Japan, where did HE end up? Is he somewhere in this city?'
If he was, then that meant trouble for him, especially if he has one of the Infinity Stones. Without backup, fighting the Goblin would be difficult for him. Whether he admitted it or not, he was far stronger than him in every way. The Avengers had to locate him eventually, but he couldn't rely to heavily on that theory. So, for now, perhaps it was best to make the most of his situation. Going to Japan was something he always thought about doing, after all.
He heard a loud crash in the distance, and a puff of smoke erupted into the sky. Peoples screams were immediately heard, as his spider-sense tingled. No matter what country he was in, hero business was the same. He knew what he needed to do, one way or another. Quickly he shot a web from his wrist and attached it to a building across the street. Once he jumped off the ledge, he began swinging down the streets, shooting off one web after another to keep his momentum.
As he swung to the next corner, he released his web at the peak of his momentum and let gravity carry him the rest of the way. Landing, he perched himself on the nearest building wall and stuck there, observing the scene below. The civilians were running in a panic from whatever was inside the cloud of dust. It was tough to make out, but once the figure stepped out, he knew exactly who it was. Standing there, tall and proud, was a villain known as The Rhino. His build was tall and wide, but just small enough to fit into his rhino costume, which consisted of leather and metal plating.

'The Rhino? What's he doing all the way in Japan?' He doubled back, 'Then again, I can say the same for myself. Either way, I better stop him'

Leaping down to the surface level, he was just about to address the villain with a witty remark.

However, suddenly a massive tree branch flew past him, stretching and bending as it traveled. It grabbed the Rhinos leg and gripped it tightly. Though it tried to pull on him, Rhino easily broke it with a single stomp.
"Damn!" A voice shouted behind him. Spider-Man turned around and observed the hero. It was someone wearing a skin tight dark blue suit, with brown armor on his joints and feet that looked strangely like the bark of a tree. His face was completely covered by a mask of the same material, his eyes being the only thing shown. Spider-Man watched as the branches retracted back into his arm, and he took a defensive position. Spider-Man had never heard of any super powered heroes in Japan, then again, he never bothered to do the research.
With the arrival of the new super powered being, a crowd began to emerge. Rather than run away, people began to cheer and take pictures. Were they that confident that this hero would win against Rhino, Or, were they just being stupid?

"Hey! New guy!" The unknown hero shouted, "I don't know where you came from, but I can take it from here."

His over confidence was a turn-off for Peter. Was this how he sounded to other people? If it was, then it at least does the job of annoying them, "The Rhino is my problem, Groot. I've taken him down before and I can do it again-"
His spider-sense went off, and on instinct he jumped into the air. Rhino came barreling down his direction, stopping just where he had jumped. The arachnid landed a few yards behind him, staying low to the ground.
"Rhiny!" Spider-Man whined, "We were having a lovely conversation about your ugly mug!"

The Rhino turned around and faced Spider-Man, not so much as a grin on his face, "I'm not here for you web-head! But I'm glad I get the chance to squash you!"
"Like that will happen any time soon!" He provoked.

With a loud snort and a puff of air, Rhino charged toward the hero again. Spider-Man quickly jumped right over him, landing just behind him and readying himself for an attack. However, The Rhino simply kept going in one direction, not bothering to slow his speed.
"Hey! Where you going, big grey and stupid?! The fight is over here!"

The other hero moved next to him, a terrified look on his face, "He's heading to UA High! The students would be just arriving by now!"

A high school, of course he'd target a place as populated as that. No matter where he may be in the world, villains still target the innocent, "Well then, let's not waste time Groot!" A web shot from his wrist, and he slung himself into the air.
The other hero shouted at him as he left, "My name is Kamui Woods!"

He swung ahead of the barreling villain and moved toward the school. The building was shaped like an H in its design. The wall separating the building complex from the street sat at roughly 24ft tall and stood a far distance from the actual building. It was clearly a well-funded school, meaning it likely was well populated. As he came closer, he saw students walking through the front gate, some already halfway to the building. They didn't notice the threat coming their way.
"Incoming!" Spider-Man shouted, grabbing the attention of at least most of the students. Without warning he shot several webs from his free hand, attaching them to the backs of the teens. Yanking on the strands, the students were pulled up just as Rhino charged through, busting the sides of the gate with the horn on his head. Just as he passed, Spider-Man lowered the webs down and let the kids back onto the ground, "Get to safety!" he shouted, swinging off the branches of the trees in the complex.

He came closer to the building, reaching the fountain in the center of the clearing, standing there was a young boy, no older than 15. He stood out a bit, given his green hair and smaller body. In noticing the monster, the boy dropped his bag in a startled position. He looked to fiddle with himself, trying to figure out what to do. Rhino didn't care who was in his way, much less who would die. Shooting a web at Rhinos back, he pulled himself forward and flipped his body over, landing in front of Rhino. "Emergency stop!" He shouted, planting his feet firmly into the ground. The concrete broke as his feet dragged across them, leaving a trail of damage behind them. He tried grabbing the Rhinos horn and turning his head to divert his movement. As the vibrations of the struggle surged through them, the kinetic energy built up in the hero's gauntlets, glowing a bright blue within the seams.
Finally the Rhinos movement stopped, just before the young boy, who stared at the arachnid in awe.

"Move, kid!" Spider-Man grunted, using his super strength to hold the villain back. The green haired boy moved from the spot, but he didn't go far. Instead he made his way to the tree and watched from a distance, pulling out a notebook excitingly.

"Out of my way, bug!" Rhino shouted, throwing his horn up and sending the arachnid flying into the air. As he came back down, he threw both fists against his head, releasing the kinetic energy from his gauntlets. The wave of power pinned Rhino to the ground, dazed for a moment.
"Aw, is baby sleepy?" Spider-Man taunted, looking around to assess the area.

That's when he noticed a golden glow in the fountain.

He made his way over and stared down into the school fountain. Drowning in the water was a stone of pure gold, sparkling under the sunlight as it sliced through the liquid. He kneeled and reached in gently, treating the object like a fragile flower. Lifting it up, he brought it close to him as the water dripped to the ground.

It was an infinity stone.

"How did you get here, little fella'?" he asked aloud. He didn't remember Goblin grabbing the other stones. However, if the blast from their collision was big enough, it could have easily caught the stones as well.
"There it is," Rhinos voice came behind the spider, his shadow towering over him. He turned around quickly and saw him standing tall, having quickly recovered, "I've been looking for one of those stone things."
"Well you can buy them at your local jewelry shop. I'm sure your imaginary girlfriend would love a diamond necklace."
Rhino lifted his arms and smashed them down, just as Spider-Man leapt and backflipped over the fountain. Rhino's attacked crushed the side of the fountain, destroying a part of its structure.

The green haired boy studied the fight and wrote into his notebook. He had never seen these two beings before, so he figured they were very new. Though even if he was fanboying over the scene playing out, he was also genuinely curious and concerned. A villain was attacking the school without any warning, and this new hero came in to protect them. Where did they both come from? He had never seen or heard of this red and blue hero before, so was this is debut? Wouldn't he have read something about him prior? It was hard to focus on a single question as he watched the fight go on.

Spider-Man dodged yet another attack, clasping the stone with both of his hands. He couldn't let the stone out of his grasp, especially if The Rhino was looking for it. As The Rhino came charging with his horn, Spider-Man released one of his hands and clasped the stone tightly in the other. Using only one hand, he grabbed the horn and twisted his body, turning the Rhinos direction of travel. After turning him 90 degrees, he pulled back suddenly, forcing the Rhino to trip over his own momentum and end up on his back. The ground cracked and broke on impact, creating a small crater where he fell. When he was down, Spider-Man leapt back to create distance.

"I'll crush you, you bug!" Rhino shouted, attempting to get onto his knees.

Just as he managed to get up, he was suddenly smashed back down. The cause of which caught the hero off guard, as it appeared to look like a giant fist pinning the Rhino to the ground. The fist was covered by a large purple glove but was still tight around the limb. As the fist released the Rhino, Spider-Man was able to get a good view of the body it connected to. It was a woman, looking to be some sort of giant standing 5 stories tall. Her costume was a collision of purple, orange and tan colors. The purple sat on her arms, legs and chest, while the tan connected those parts, and separating them were orange highlights. Her mask was a simple cheek bone cover, with horns sticking from her blonde hair. She had a smile on her face as she kneeled and stared at the young arachnid hero.
"Hey there, cutie," She giggled, her voice loud as she was gigantic, "What's your story?"

Peter was not unfamiliar with people who were giant. A superhero back home had the same kind of ability. It was just strange to see someone else using it. Japan clearly had its own set of superheroes that he wasn't aware of.
"Um …hello giant pretty woman," he awkwardly greeted.
"Aww well aren't you a sweetheart," She smiled, "My name is Mt. Lady. What's your name, new guy?"

He composed himself. Even though Spider-Man was naturally confident, his Peter side still shows when he talks to girls, "I'm-I'm Spider-Man. Nice to meet you."
All of a sudden, the woman's size began to shrink rapidly. She went from being 5 stories high to be a little over 6 ft. The sudden change caused her to be slightly airborne, nearly losing her balance. Spider-Man quickly caught her, to which she gave him a sweet grin, "My hero," She teased.
As she stood up straight, a voice caught their attention, "What's going on here?!" It said.

They turned to see who the voice came from. It was a man in dark clothing, with long black hair to match. Around his neck was a large scarf looking material. For some reason, his hair was sticking up for a moment before it suddenly goes down. He didn't look too friendly, but he also didn't look like he wanted trouble. After all, Peter's spider-sense hasn't gone off yet.
The man approached them, giving them a stern look that was specifically targeted at Spider-Man.
"You're no fun, Aizawa!" Mt. lady shouted, "Turning off my quirk like that! I could have hurt myself if not for this dashing young hero," She leaned on the young hero, who blushed under his mask.
"That's my second concern," Aizawa scolded, staring daggers at him, "I've never heard of or seen this 'hero' before. So, who are you?"
Spider-Man tried to compose himself as the beautiful young lady hung onto his arm. Just before he could speak, the young green haired boy from before rushed over to them.
He stopped just in front of Spider-Man, finding that he wasn't that much taller, "That was so amazing! I can't believe you took him down with one hand! And then how Mt. Lady finished him off was-Wow!" He started to fanboy, but Peter found it kind of charming. It wasn't so much obsessive as it was pure passion for something that made him happy. It reminded him of his love for science. Besides, he loved interacting with the few civilians who liked him.
"Thanks, kid. I've fought The Rhino before, so I know his tricks."

"So, what's your quirk?" The kid asked, "Is it super strength, because you don't look that muscular, yet you went toe to toe with him! And then there was that agility!"

"Midoriya!" Aizawa shouted, silencing the group, "Step aside."

Midoriya clearly feared this man, as he immediately did as he asked. When Aizawa approached Spider-Man, he stared him down, even with Mt. Lady still hanging onto him.
"I've never heard of you. I've never seen you. And that bothers me. So, here are my questions. Who are you, why are you here, and do you have a license?"

"A license?" Spider-Man asked, "You'll have to be more specific about that. But you can call me Spider-Man."
"Spider-Man," He said coldly, "And what are you doing here?"

He needed to come up with an excuse, because saying he 'doesn't know' probably isn't a good idea.
"Well, I am …here …because…" his eyes drifted to the school. He was on his way to school before he got wrapped up in all of this, so it would technically be the truth, "I was on my way…too school?"
"Ooo," Mt. Lady said, "I see. So, you're a student here then? An upcoming hero? That makes you what, no older than 15?"
"16," he said, correcting her.
"Well, I do like young men," She cooed, "Means I get to keep them longer."

He was about to question where this flirting lied, but then remembered that things worked differently in Japan. The legal age of consent was 13, so dating someone around the age of 15 was normal. That aside, it wasn't normal for him as she was likely about 20.

"Mt. lady, please," Aizawa pushed, "He can't be a student here because I am a teacher, and I've never seen him on campus."
Spider-Man raised his hand, "I'm wearing a mask."

"I've memorized the quirks of all my students, as well as those I don't teach. I haven't seen yours. You shot webs from your wrist, predicted your enemies' movements like a 6th sense, and had strength proportional to yourself."
He was awestruck by his analysis, "Wow…you're good."
"The only way you could be a student here is if you were a transfer, or a student from abroad. Either of those correct?"

"Ah…well…" he had a feeling if he didn't give a good answer, it would cause a lot more trouble. He just needed to say whatever he could to escape the situation, "I'm …a transfer from America. I'm taking a semester abroad…here at …UA."
As he came up with his excuse, he suddenly felt a burning in his hand. It came from the hand still holding the infinity stone. Was it reacting to something? Why was it getting so hot?

"You realize," Aizawa said, "That if you're a student, then you had no right to harm the villain without a license."

Spider-Man tilted his head, "Really? Works differently back home."

"Aw let him off easy Aizawa," Mt. Lady pushed, "If he's foreign then he needs to learn the rules. Simple as that. Make it a warning and call it a day."

Just as she finished, Aizawa pulled out a cell phone and dialed a number. When it started ringing, he put it to his ear, "Yes, it's me," he spoke, "I need you to look something up. Are we expecting any students from abroad to spend a semester?"
Peter became scared. He needed to think of a way to escape these people, but with Mt. lady still hanging onto him that may be difficult. She could easily grow and catch him if he tried to escape, depending on if she wanted to catch him.

"I see…" Aizawa continued, "Thank you," With that he hung up, and stuffed his phone into his pocket, "It seems we've been expecting you, Mr. Parker."

Spider-Man utterly froze, "…What?"

"That's you, right? Peter Parker. Quirk; Spider. Can do anything a spider can to a certain extent. Alias chosen; Spider-Man. Assigned to class 1-A."

He had no idea what to say. He was bluffing his way through the conversation, but they've been expecting him. How is that possible? There shouldn't actually be any records of his arrival, much less with all that information.
On another note, why did he call his powers a 'quirk'? And what do his powers have to do with this school. Mt. Lady asked if he was a student, and an upcoming hero. Does that imply that this school was for people with super powers, like Xavier's school for the gifted?
"Mr. Parker, make your way to the principles office before homeroom. We'll give you your school outfit, and we'll get the final paperwork figured out."

Aizawa started to walk away, without as much as another care to give.

"Wait, Mr. Aizawa," Midorya spoke up, "Class 1-A is already full. How would we fit him in?"

Aizawa didn't bother to stop moving as he answered, "I'll explain it to you during homeroom, so don't be late Midorya."

As he left, Midoriya approached him, "I can't wait to work in class with you! I have so many questions about your quirk!"
"Right …" Spider-Man said, still processing everything, "At this school …for superheroes?" he half questioned, not making it too obvious.
"Yeah! Totally!" Midyroiya said loudly, "You're gonna love it here! This is where the best upcoming heroes are taught."

With a giggle, Mt. Lady finally released Spider-Mans arm, taking a step back and putting a hand on her hip, "Well, I better get myself back to work. Crime doesn't stop itself, after all," She winked at Spider-Man, blowing him a kiss, "When you get your hero license, look me up cutie. I'll be waiting."
She then grew several stories and stepped over the walls of the school complex, making her way back into the city.

Spider-Man just stood there, dumbfounded by how all of that went down. What he gathered from this experience was that here in Japan, superheroes with powers are taught in schools like this, then released into the world. Does that make them supervised by the government? That would explain the part about the license. So, he can understand that superheroes have a more thought out system here. What he didn't understand was how the school had records of him, when he never applied to go here abroad. There was no way that could happen out of nowhere, this whole situation doesn't feel like reality.

Reality.

Turning his back To Midoryia, he opened his hand and looked at the stone. It was yellow, the color of the Reality stone. Anyone holding it can alter reality around them however they choose. He was holding the stone when he made the excuse and it started burning. He must have unconsciously used its power to enroll him into the school.
Actually, this narrows things down. If the Infinity Stones still work, then the Space Stone didn't send him through the Multi-Verse. Supposedly, the Infinity Stones can only work in the Universe they were born in. So, he must still be in the same universe, that much was good to know. With the stones involved, he could have ended up somewhere far worse in the universe. Yet, he's in a version of Japan with a hero system he's never heard of. So, what does that mean? An alternate timeline or dimension?

Should he go along with this, especially if he doesn't really have time to deal with it? If The Rhino is here, who's to say there aren't others? But at the same time, he can't go hunting for them without a license, it would likely mean getting arrested. Though he wasn't unfamiliar with running from the police, other heroes could get involved too. This was a very complicated situation, and he needed to play his cards right.

"Peter, right?" Midoriya poked him, trying to get his attention, "You should probably head to the principal's office."

He turned to him, regaining composure and hiding the stone behind his back, "…Right. Ok."

He was too confused to think properly. There was a chance this was an alternate dimension situation, a concept not too far off. Thor, the god of thunder was from another realm. This couldn't be too different. For now, he needed to play things safe and go along with it.

Gripping the stone tight, he made his way to the school.
