So I've had this idea in my head for a long time, but I didn't want to start because of how nervous I was for making my first crossover.

But after seeing someone already did it, called Deku Heart btw, I finally had the confidence to start this. Hope you all enjoy!


Class 1-A watched as their sensei was beating up the villians that had just come from the portal. He was making quick work of them, as he fluidly knocked each and every one of them out.

"Wow. Look at him go," Izuku said to himself as he kept looking at the display his teacher was showing.

"This is not time for an analysis!" Iida yelled to his friend, "We've got to evacuate!"

"Right." he said as he joined up with his classmates.

"I'm afraid I can't let you do that," a voice said, before black mist showed up out of nowhere. It had 2 yellow eyes as it stared down the students. All of them had shock on their faces as they realized their exit was blocked.

"Greetings. We are the Villian Alliance I apologize for the presumptions, but we took it upon ourselves to enter UA academy, the base of heroes."

Right at that moment, Bakugo and Kirishima ran up to the mist man, and tried to attack him. Bakugo let loose an explosion, while the redhead hardened himself and went to hit him.

"Bet you didn't think we'd be able to do you in before you got the chance!" Kirishima yelled to the mist.

However, both of their attacks had no effect, as the mist man was still floating.

"It's no use! Run you two!" the voice of the hero, Thirteen, said to the two boys.

"You will be scattered," the mist said as he started to envelop the whole class and the teacher. Some of the studnets managed to find a way to escape the dome of purple mist, while the others were starting to get transported to other parts of the USJ.

Izuku looked at this, and his face went a little pale. All his classmates were getting separated, and would have to probably fight villians that won't hold back in killing them. And he couldn't do anything to stop this from happening.

But then, as fate would have it, Izuku spotted something metal on the mist being's body. It looked like all the mist was concentrated in the metal, and that it flowed from its top and bottom.

That's when he started running towards the mist. While he was running, his mind quickly formulated a plan of action.

"Midoriya!" the voice of Ojiro said as he noticed his classmate running towards the mist.

"Deku!" Bakugo yelled, "What the hell do you think your doing?!"

Izuku didn't respond as he kept running. Everyone was confused at what he was doing, and some were even telling him to stop, but he didn't let that bother him. He knew what he had to do.

The mist was not too concerned with what the boy was doing, but he didn't let his guard falter all the way. He had no idea what any of the class's quirks were, although he could make guesses, so he didn't know what the boy was planning.

Izuku jumped into the air, and started to channel the power of One for All into his hand, as he got ready to inflict a blow. His hand formed a fist, but after a little recollection from the Quirk Assessment test, he instead changed his hand to the flicking position.

The greenette pointed his hand at the mist man, before yelling, "Guys! He has a piece of metal on him! That's probably his weakpoint!"

This got a reaction from the mist, that was one of surprise. That's all Izuku needed, as he flicked his middle finger, "SMMAAAAASSHH!"'Since his body is concentrated at that metal part, that's where most if his energy must be stored. If I break that, then his quirk will go haywire and it'll be hard for him to teleport people anymore. Then Thirteen can suck up this villian with her quirk,' Izuku thought as the impact from his flick hit the metal, and actually broke it.

The mist could not express his shock anymore, as his quirk started going out of control. He pulled away from the students, so he could get himself back together, but not before giving an angry scowl to Izuku.

"Very perceptive, boy," the mist said, "But I cannot allow that action to go without consequence."

He then used his quirk to make a portal underneath the boy. Izuku didn't see it coming, and he was then warped to someplace unknown.'While it is true that I have no control, I also gain increased power to my quirk. I was lucky to even get that boy sent somewhere. Before, I could just warp people to different places on Earth. Now I can warp people across the multi-verse!' the mist thought.

"Deku!" Uraraka called after seeing her friend get warped.

"There is no escape now students." the mist said before he got ready to send the students to another dimension entirely. However, he was stopped by Thirteen, who started using her quirk to suck up the mist.

"Black Hole!" Thirteen yelled as she was sucking up the villian. He had tried to summon a portal behind the hero, so her back could get damaged; which would've worked if Izuku didn't break his restrainer.

But since he couldn't control his quirk anymore, he just started making portals all over the place; nowhere near the hero. He was victim to the power of the Black Hole as he was sucked up into the hero's fingertips.

After the last remnants of the villian were gone, Thirteen shut off her quirk, and turned towards the students, "Villian secure!" She then gave them a thumbs up.

"Quickly everyone!" Iida called to his fellow students that were still at the USJ entrance, "We must get to the other heroes and tell them about this!"

All the heroes-in-training present nodded their heads as they followed their Class President through the door. All the students were worried what would happen to their other classmates, but they were sure the other pro heroes would be able to stop them.


Meanwhile with Izuku, he was floating through a purple and black swirling vortex. He was spinning out of control as he kept going to his unknown destination.

Multiple thoughts filled his head as he was spiraling, all of them laced with either panic, fear, or worry, 'I hope Thirteen was able to suck up the villian. I hope my classmates aren't hurt! Where am I even going? I hope the others that got warped didn't have to go through the same thing I'm going through...' There were plenty more, but these are just a few.

While Izuku was trying his best not to get sick, he would catch glimpses of a bright light at the end of the vortex. He couldn't see beyond that, but was able to notice that the light was more blinding the closer he got.

When he finally passed through the light, he was able to feel the wind flow past him, and he felt a feeling of weightlessness. He compared it to going down on a roller-coaster, except multiplied.

He was still spinning in the air, so he couldn't really make anything out. All he was able to see were glimpses of green and black.

That's when realization dawned on him.

"I'M FALLING! AAAAAHHHHHH!" the boy screamed as he kept hurtling towards the ground. Panic had taken the wheel, as Izuku couldn't think of anything he could do to stop himself from becoming a red stain.

He started crying a little, thinking that this would be the end of his tale. He never wanted to die like this! He still had so many things he had to do. He needed to become the new Symbol of Peace, because All Might's time was running out! He had to get back to his home to help his friends, because they were facing a villian threat that could kill them! He couldn't be done! Not like this!

"I can't be finished yet!" Izuku said to himself with determimation oozing from his words. He managed to force his panic into the back seat so he could think a little rationally.

'So I'm falling from the sky towards the ground. Let me think this out. If I use One for All to stop my fall, then I'll have a broken arm, and if villians show up, I'll be a sitting duck. Wait a minute! What if I generate the quirk through my finger! The force from the flick should be enough to at least slow me down. I also will still have my other fingers if I need to fight. Okay! When I get closer to the ground, then I'll do it!'

Izuku grabbed his right wrist with his left hand, and tried to form his right hand into the flicking position. He tried to move his middle finger, but found that it was broken, so he moved on to the index one.

He was still spinning, so it was relatively hard to try and figure out how close he was to the ground.

"Almost there..." he said before he infused his fingers with One for All. He was now maybe 100 feet in the air, and still falling.

At around 20 feet, Izuku knew that was his one and only chance, "Now!" he exclaimed before he flicked his finger.

While the action did result in him not splatting onto the ground, it also created a huge gash in the terrain. The ground caved in on itself a little from the impact, and caused the once grassy plain to be damaged.

Even when Izuku flicked his fingers, he was still spinning. So instead of falling straight down, he flew forward until he collided with a house that was nearby. When he made impact with the structure, he made a hole of his body on the wooden exterior.

When he landed on the inside, he found himself on the upper floor of the house. He finally started to slow down once he crashed onto the floor of the room. He managed to leave a pretty decent indent on the wooden surface.

Izuku was feeling many things at that particular moment. He felt fear, because he didn't want to know what the owner of the house would do to him when they saw the damage. He felt pain, because of the fact he crashed through a house, and broke his other finger. He also felt sick, because the spinning wasn't something he wanted, nor needed.

After a few seconds of laying on the floor, Izuku was starting to get up. As soon as he had placed some of his weight on his left hand, he heard a small crack before the indent suddenly turned into a hole, taking the greenette to the bottom level.

Izuku made a loud thud as he hit a counter top. The boy didn't feel like getting up at that point. The pain was pretty unbearable, but he was still able to remain concious.

"Uggh..." the wielder of One for All groaned as he slowly looked at his surroundings. There was an obvious color scheme of black and silver with the interior. He could see a stainless steel fridge, a dishwasher and sink of the same color, a black oven, black covered pantries, and a combination of the two colors for the counter top color.

The boy layed in his position for a good while; thinking about his situation, 'So I still have no idea where I am. My guess is that this is a random home, because of the fact the portal was in the air, so I would've died by the fall. I hope the people of this house are understanding. Although, I kind of doubt they would believe that I fell from a portal in the sky.

He tried to get up multiple times, but found it near impossible because of his body screaming at him for repair. So the boy opted to just stay on the countertop.

"Maybe I should just get some rest. I can't do anything anyways," Izuku said to himself before closing his eyes and letting sleep overtake him.


I know somethings may or may not be accurate with the things I wrote. Since I haven't looked at Neptunia in a while, somethings may not be accurate. If you can, letting me know what is false would really help.
