In conclusion. Things happened.

Well, in actuality, a few years went by. Crazy how short that time felt. It was weird for Izuku to get used to switching bodies every other day, but that's just how things ended up.

The boys discovered that the next day they would switch minds. There were attempts to stay awake to bypass the effect, but at the stroke of midnight, both boys would pass out for a minute and be forced into the other's body, with almost no time to speak to the other. That was really what sleep amounted to. It gave them time to talk about their day, teach each other about the world and plan ahead. Though tonight after mentioning the phrase "The stroke of midnight" and Eren's subsequent confusion. Izuku was forced to explain the story of Cinderella to his body-swapping partner as he eagerly listened.

The dream space was still dark, void with nothing but what looked like glass separating the two boys as Izuku continued.

"And at the stroke of midnight, her fancy dress and carriage turned back to normal, the riders back to mice and the carriage back into a pumpkin. The magic had worn off,"

"Why did the godmother's powers only last until midnight?" Eren asked, enjoying the story but unable to reconcile this clear 'plothole.' That was another new word he learned. "Powers with a time limit are useless. What kind of change could she make if she only had half a night?"

Izuku could only really stare and shrug. "I don't really think it matters. Suppose she had 13 years of godmother power. It wasn't like it was going to do her any good pretending to be a noble. She would get the prince to love her because that's just the kind of person she is no matter her position in society. She's kind of like Mikasa, constantly determined to protect us. Being able to do it forever would be nice sure, but she's happy as long as she can do it now." Izuku blushed a bit. Rubbing the back of his head. "I mean, she's…"

Eren stared at the boy, an unamused holding back the urge to make fun of him.

"Stop looking at me like that," Izuku pained, unable to get another word out before Eren started.

"It's nothing," Eren smirked as he stood himself up and did a few stretches. They tried running in here, but after a reasonable distance, you just ended up back at the mirror. Eren rubbed his stomach. "I wish we could eat in here. Food from the mess hall is the worst. You know what your mom is making tomorrow?"

"Probably eggs in the morning and ramen later." Izuku looked up as he tried to recall the day. Staring into the black abyss as he attempted to think about anything but the training tomorrow, "Eren, I'm going to be honest, I think joining the military at twelve was a mistake for both of us. You, because you're going to get yourself killed by a titan and me because you keep exercising in my body!"

"I can't help if your body feels weak!" He shot back, "Besides, we're pretty much even anyways. I aced all those tests on the days I was on. Your body can take a little physical pain if my mind is forced to understand those variables." He paused for a moment looking at his friend's matching green eyes.

"Besides, you wanna be a hero, right?"

Izuku sighed but could only nod in agreement. "That's true,"

"Your welcome." Eren did a smug little bow before going back to laying down on his side. A casual pose with a hand supporting his stupid head. "I'm gonna wake up soon; anything special happening today? On my side, we're graduating from the training corps. Setting up in Trost before the whole celebration where we choose where we go. You'll just have to deal with maintaining stuff on the wall and other trainee duties."

Izuku could only stare in shock. It felt like yesterday he finished up his final exams. He expected maybe a few more days of it before everything started happening. It was a bit anxiety-inducing.

"Y-Yeah, it's mostly the same on my end," The fourteen-year-old sighed, "Just school, nothing insane should happen."

"How's Katsuki been?" Eren perked up to ask. Not taking his beatings lightly made interactions with him less frequent, but it made Katsuki careful. Instead of punching them now, he would blast pebbles from far away using his quirk. Called it a hand cannon or something stupid like that. It was a level of petty the two boys enjoyed joking about. Though Eren knew he wasn't that great at standing up for himself. Though the beatings Annie gave, Izuku counted for something to help him instinctually block.

"Less than usual, you don't need to get revenge for me yet, anything I need to know while I pretend to be you?"

"You should stop that, you know, Reiner has started suspecting that we might have mental problems. I don't want people thinking you're how I act like. Just introduce yourself as Izuku already!" He shook his hands, tired of the games, "Your mom operating just fine with me every other day."

"Cause you didn't hear the nights she spent crying before she finally accepted her got a two in one deal with us," Izuku retorted.

A guilty look painted Eren's face. He had a point, but it didn't make him anymore right. "Fine, but when we become scouts, I'm telling everyone about you,"

"Fine," Izuku resigned, laying himself down the same way he was. "See you tomorrow,"

"Later," Eren laughed before closing his eyes.

Eren's eyes opened to his second usual ceiling. The light from the sun glazing over his skin as he rolled out of bed and did a few stretches, feeling Izuku's bones and developing musculature as he rolled his shoulder. Eren sighed; Izuku didn't listen to his posture complaints.

The food on this earth meant gaining muscle was easier. Maybe Eren could steal a few non-meat recipes for use back home.

Getting dressed and moving to the dining table, Inko noticed and smiled. "Hey Eren, How was yesterday?"

It was a bit strange as he got used to her addressing him as himself in this body. But it was nice. After what happened back home, she was like another parent almost. Though it made Eren feel guilty about how nobody else back home could experience life like this. Armin talked to him about all those things when they were kids, the ocean, skys that glow like fire. All of it was free here. Anyone could go and visit them. But even then, Eren found himself with a desire to see the ocean back home. He wanted humanity to be able to live like this… To be free.

"It was good, another trainee questioned my resolve to go into the scouts. I ended up going into a bit of a rant against him. I think it made an impression on everyone else."

"You're not making life hard for Izuku, are you?" She asked, placing the boy's breakfast down. Eren thanking whatever put him here before digging in and speaking with his mouth full.

"Nah, today should be easy for him. Just cleaning up the walls and fixing up cannons."

"Oh, you were at... Trost, Right?" She asked with a tilt of the head—the words bringing a smile to his face. Inko really did want to learn about Eren's world. Or at least what her other son was doing in it.

"Yep! Izuku should just be hanging out with Mikasa and Armin for the most part today. He still hasn't told them about our condition. I noticed that some days Mikasa walks up to me looking a bit excited, but after she makes eye contact, she just stops and looks disappointed. Like she can tell just from my face."

"You should see Izuku whenever I mention her. Beet red and desperate to change the topic. I'm glad my boy is talking to kids his age… Well, even if they aren't from this world." A few years ago, Inko would have thought those words insane, but even without proof, she just came to accept it. The level of detail was unlike anything else, and this couldn't be a split personality like those TV dramas. Maybe it was Izuku's quirk, but none of that mattered right now. It just made her nervous to think about her son fighting against those creatures Eren described.

Eren simply smiled and continued eating his food. Izuku got along with Mikasa and Armin much better than he did anyway. Though he couldn't really find it in himself to get upset at that. He liked hanging out with Izuku too, maybe more than them.

In any case, this was just another day in paradise for Eren as he finished up breakfast and got up to leave.

'Just another day in paradise,' Izuku thought to himself a bit sarcastically. Hands full from the cleaning supplies he was carrying over and body tired from all the heavy lifting.

"I'm joining the scouts," Connie said out into the open as Izuku turned around to stare. "It's not because of yesterday. It's just… I can't be in the same group as Jean," he insisted as Izuku proceeded with cleaning a nearby cannon. Connie always said the military police was where he wanted to go. It made no sense for him to—

"My choice is made. You can't change my mind," He ended before going back to work. The entire exchange felt like a video game interaction. Izuku didn't seem to mind that though, He just gave a reassuring nod and proceeded to look over the city.

The city of Trost became home for a large number of people after Wall Maria fell. It was going to be a long battle, but it seemed like humanity could finally take back what was—

"Behind You"

A voice called out to Izuku as he turned around. The air was still. His hearing was silent. But fear continued to well inside himself. His body frozen in terror as it suddenly happened.

A flash of lightning lit up the sky. Coming down from the atmosphere and smashing into the air in front of him. The heavy feeling of steam and sight of bones and building themselves up in the air. This titan was blood red. Like it's face was nothing but muscle. The eyes staring down at them. It's head only visible with its massive height hidden below the fifty-meter wall.

For the first time in his life, Izuku learned of the terror Eren spoke about. The sight of the skinless monster in front of him. The titan that ruined so many lives. He was staring at the being right in front of him.

Izuku felt numb.

Until he felt his legs move.

Class was really boring. Honestly, the entire day was a bit boring. The only thing that really evoked any feeling today was the sight of a giant villain wrecking some train tracks before a hero stopped them. Eren would be lying if he said he wasn't terrified. The sight of a giant man fighting and being beaten and arrested by a giant woman hero was frankly terrifying. It brought back memories of that massive titan blowing a hole in the wall of his hometown. Causing the death of his mother and a massive reduction in human land space. It's red muscled face was burned into his memory along with the sight of the titan that ate his mother…

What Eren would give for one moment with the skinless bastard.

"...hero notebook number ten? What is this shit, Deku?" The cocky blonde spoke, looking down on Eren, making fists and gritting his teeth at memories.

"It's Eren," He muttered out, voice causing a slight amount of fear to reveal itself in Bakugou. Though his lackey's staring caused him to bottle it up and continue like he was uninterrupted. He planned on doing this. He had to build up the courage to continue this far. For Eren, that was a good sign. "I write notes about cool quirks I catch sight of and think about how they can be used. Can I have it back?"

"Thanks for the answer, urine," The joke getting snickers from the sidekicks as Eren stared unamused. "If this is volume ten, I don't think it'll be too much trouble if I do this," He laughed as in one quick motion he blasted the notebook with his quirk and tossed it to a friend by the window like a basketball player passing to a teammate for an easy layup.

In a basketball metaphor himself, Eren slam-dunked his hand into Bakugo's face before grabbing his things and checking him over a desk as he ran. Apparently, that would get you a foul, but Eren didn't plan to continue playing. Izuku made him promise to avoid fights.

Dashing down the stairs and outside the building, he caught sight of the notebook. Grabbing it before shoving it into his backpack as carefully as he could on the run. The sound of cursing and the smell of assholes not far behind.

A short dash was made towards a nearby tunnel. Catching his breath with a smile on his face as Eren heard Bakugo grumble something. Calling him a bitch for running, but Eren ignored the bait. Before long, the explosive boy kicked some dirt and made his walk away. Leaving Eren in a good mood. He would probably have to warn Izuku about Bakugo trying to start something else. But for now, this was a win.

Though, of course, Eren couldn't just have a win. Certain he was cursed, Eren watched as slime began to bubble out of the sewer vent.

Eren recently learned about the internet and how to find new information. Getting that much data into his system was a shock, but he'd gotten used to it over the few months. Learning about hero society and how it works was incredible. It could even become useful back home if he made it high enough in the military—the knowledge about how giant quirk users are restrained in particular. There was so much he could do for his world, and he was sure he could do it. So why was he dying?

Why did fate decide to send a villain with a sludge quirk decide to attack him?

Eren Ran

"Hey! Get back here, brat!"

Why was the villain suffocating him? Using his fluid body to force himself inside Eren's mouth and nose.

"A decent enough body to hide inside. Sorry about your organs I'll have to squash, kid."

Why was Izuku going to die so young?

I'm going to wipe out all the titans.

I— I won't stop until they're all gone.

Every last one.

"I'll kill anyone who tries to stop me,"

"Wake up, Young man." A deep voice called out to the sleeping boy. Massive hands lightly shaking him.

Barely standing up on his own, he opened his eyes to look at a massive man standing in front of him. He looked familiar, "Hmhma...All Might?" He mumbled out, looking up at the face with the sun behind him.

"In the Flesh!" The voice shook Eren's body awake as he realized the massive man in front of him was real. Seemed like the man wanted to snap him out of the daze because right after scaring the boy, he let out a laugh. "Welcome back to the land of the living! You're lucky I caught the struggle happening as I was flying by. I'll admit the villain got away from me one time but not again! Thanks to you, of course!"

Eren could only stare in awe. He wasn't raised here as a child, so he didn't really have the emotional connection all the other kids have to this monolith of a man, but he could still feel the immense power and pressure. It was unfair for someone to be that powerful and that morally good.

Fuck, Izuku would need an autograph. He was already going to be really upset about missing out on this chance. He had to get him something.

"M-My notebook, can you sign—"

"You mean," He paused for half a second for dramatic effect. "This notebook!" The titanic hero held out the notebook in his massive hands, already open and already signed. Lowering into Eren's hands as he nodded and smiled on behalf of Izuku.

"Well, you know how things are, Crime and whatnot, I'll be heading away now!" He quickly spoke, getting into his position to jump away as soon as he came. All Might couldn't fly but could soar with nothing but the power of his legs. It was insanity seeing him flex his muscles to get ready for it.

Upon seeing the display of strength, Eren reached out a hand. He had to ask. Someone with his perspective and power had to know the answer.

"All Might wait!" Eren called out. The man pausing and turning his head. A smile still on his face.

"Can—"

Flashes of his city in chaos.

Flashes of his mother being eaten by a titan.

Humanity trapped in nothing but a cage.

The promise he made to Armin.

They were going to see the Ocean.

Izuku's wish to become a hero...

"Can someone as weak as us become exceptional?"

All Might Paused.

"Can someone without power make real change in the world?"

All Might stared at the boy. His smile faded, and for the first time, Eren saw how he looked without that Everbright smile. This world's symbol of hope.

He turned his face away. Back towards the direction, he was going to jump before Eren interrupted him. Voice low but just as powerful as he spoke.

"Someone without power cannot change any world."

Eren felt the words cut into him. Frozen, emotionless as he listened.

"But after what I saw with that villain, You can become a hero."

All Might extended a hand out to point in another direction. Eren turned his head. The sight before him was going to be seared in his mind forever.

Eren saw the destroyed tunnel. The entire thing was left into rocky remains, the sun exposing the whole thing, street lamps knocked over, and the sludge villain was…

There were parts of green sludge everywhere, far away even. It painted the entire scene a different green hue.

Laying right there in the center of all the destruction. He saw the scalding remains of a Titan.

"You can become a hero,"

The voice spoke as Eren looked and saw All Might was gone.

Eyes focused on the skinless monster in front of him, Izuku felt numb. It was like time came to a halt as he looked over the colossal titan. The titan that broke down the walls on Eren's home. It was going to happen again. All that pain and suffering. The starvation he witnessed afterwards and the hatred would continue. His body was numb in fear of everything that was about to happen. It was like he could already see the events unfolding, and there was going to be nothing he could do about it.

Until he felt his legs move.

Izuku ran as soon as the monster formed itself from air. Jumping up into the air and screaming out. Everything hurt. The monster's face was getting closer. No…

He was getting closer to the titan. He had to do something. Body screaming as he felt determination well up inside him. He didn't have maneuvering gear on. He could only feel the clothing in his arm begin to rip as he felt power course through his body. Screaming out with all of his energy, words he didn't understand forced themselves out of his mouth.

"SMASH!"

He felt his fist impact the monster's face as it was crushed from the boy's attack. The collision and the sheer air pressure doing work as Izuku watched the monster shift off balance. Tilting backwards until he realized it was going to fall. Just like Izuku… wait.

Izuku was falling. He was a good 20 meters away from the top of the wall he jumped off. How did he get this high and far? How did his legs—

His legs were broken. He looked down and saw them flapping around and bleeding through his clothes. Same thing with the arm he punched with. Watching specs of blood fly away from his fingers like drops of rain going upwards. The titan was stopped, but now Izuku was going to die. Eren was going to die.

The only thing between Izuku and death was a few dozen meters. A hundred feet between him and oblivion.

Until he felt it. Something stabbing into him. Into one of his dead legs. Turning in the air, he saw it. Mikasa jumped off the wall herself and shot out a hook from her maneuvering gear, piercing his leg but slowing his fall as he watched her gracefully turn and shoot her second hook into the side of the wall. Shouting coming from their direction as Izuku heard the sound of Mikasa's line snap. The metal clang there wasn't enough wire anymore as it snapped straight and Izuku felt pain shoot up his body. It felt like his leg could be ripped off by the force but it held just barely.

He felt his back impact on the side of the wall as Mikasa screamed something. But Izuku couldn't find it in himself to stay awake, he felt really tired for some reason, eyes closing as he thought about home.
