Izuku's POV

They rushed back towards the JP's building. Their last stronghold in this hellhole that they called Earth. It took both his and the silver-haired man beside him's strength to pry open the door. Electricity had long since left the building and prying open the door stole precious seconds. Behind them, Izuku could hear the black nomu getting closer.

Once the door was open enough to let them slide through they were inside. Closing the door again would buy them a few precious seconds. If they were lucky. If not this might be the end for them.

Together Izuku and Yamato Hotsuin former Chief of JP's made their ways into the bowels of the building. With the seals destroyed they only had a limited amount of time before Yamato was overrun with power. Specifically the full power of the Dragon Stream.

The Dragon Stream was ancient magic gifted to the Hotsuin clan by the demon Alcor. It was sealed away in Mount Fuji so as not to destroy the vessel it was housed in. Yamato was the current vessel as the heir to the Hotsuin main house.

For their plan to work they had to use the Dragon Stream to activate a runic circle. The runic circle was drawn in their blood take over the course of a year. It would send them back to sometime before the Fall. When exactly they didnt know. If Fumi was still alive she would have been able to tell them.

A hard smack hit the back of his head making Izuku stagger slightly. Yamato's sharp command came a second later, "Don't focus on the one's we've lost right now, Izuku. We will be seeing them again soon."

"Yes, sir."

He was right. They couldn't focus on the dead. Not with their enemies so close behind them. Or their goal so close in front. They would succeed they had to. The world was counting on them to make it to the past and defeat Shigarki and All for One before they destroyed society.

Heroes and Tamers alike fell to the villains. Magic only went so far and it took time for their demons to heal from a battle. Nomu gave no quarter when it came to killing. They had to stop them before the Fall. Otherwise, it would too late.

Izuku knew their best chance would be when they knew exactly where the villains would be. Namely, the USJ incident would be their best chance. The main villains would be there and killing Shigarki would put a halt to All For One's plans. Then they could work on killing the mastermind.

That would only work though if they were sent that far back. For all, they knew they could only be sent back a few days or weeks before the Fall. If that happened they would be in a rush to prepare for an all-out assault. To strike before the enemy could. So many unknown variables. So many things that could go wrong and leave them worse off than they were currently.

Izuku was the first to enter the ritual room but Yamato was hot on his heels. A quick Agi had the torches in the room lit up. On the floor was the runic circle.

Yamato ordered coolly, "Izuku get in the circle. We will begin the process immediately."

He did as he was told entering the circle and a silver light lit up the circle. The process of using the Dragon Stream had begun. Turning with a smile on his face he looked at Yamato for the first time since they began running from the nomu. His eyes widened in surprise as he stared at his friend.

Yamato must have been injured when they tried to get away from the nomu. How had he not noticed when it happened? Why didnt Yamato say anything?

Izuku tried to step back out of the circle reaching for Yamato. Tears filled his green eyes. No, it cant be! The magic pressed down upon him with immense pressure. He couldn't stand any longer and fell to his knees on the circle.

Yamato said his right hand pressing into his left side, "I'm sorry if only one of us can go back," he grunted in pain silver eyes screwing shut, "It has to be you."

Izuku slammed his fist into the ground stuck inside the runic circle yelling, "DON'T DO THIS! WE CAN STILL GO BACK AS PLANNED! YAMATO! We can still figure this out!"

His commander and friend smiled tiredly as he shook his head and continued, "There is nothing left to figure out here. You need to go back and fix our mistakes. I believe in you."

Tears welled up in the green eyes as he tried to deny, "I can't do this alone. Yamato... you promised. You promised as long as I was your subordinate I didnt have to be alone anymore."

"Make things right," ordered Yamato, "You are probably the only one who can do it. You just have to do the very thing you taught me to do. Never give up and keep pushing forward. To believe that there is always hope. The Dragon Stream alone isn't enough. I have to stay and sacrifice my magic to send you back. You have to go."

Izuku cried, "I can't..."

"You can. You can save our world from the fate I doomed it to. I believe in you. This won't be the last we see of each other. Just promise you will be my friend again in the new world. That's all I ask."

"YAMATO DONT DO IT!"

The Dragon Stream activated around him as the door behind Yamato was blown open. A familiar blue-haired villain stalked in followed by several nomu.

Izuku tried to shout denials as the world around him went black. Yamato's body collapsing to the ground from the lack of magic and a nomu stalking towards him being the last thing he saw.

Awareness came back coupled with the feeling of falling. He thumped painfully against wood. It took him a moment to recover and regain his bearings. Surprise overtook him.

Around him were familiar wooden walls of his childhood room. On the walls were a few hand-drawn posters that he had made himself. The real posters having been thrown away when he was declared quirkless. He was lucky that the posters themselves were kept up as long as they had been.

His mother Inko had been a loving woman before his diagnosis. Any hero memorabilia he wanted she would buy him. Until he was picked up by JP's she would act as if he didnt exist. Once upon a time, her callous behavior hurt him deeply. Now it was a scar that had long since scabbed over.

With his memories from the future, he knew he could not stay here. His mother as much as he hated to call her that wasnt stupid. She would know something was off about him. With that, she might try to interfere in ways he couldn't plan for. No his best option would be to gather supplies and leave immediately. First, he needed to know what age he was.

Moving to the bathroom he grimaced at how short he was. Izuku hadn't hit his growth spurt until he was seventeen. While he wasnt as tall as he could have been from lack of nutrition in his early life he still shot up like a week. His final height had been 175 centimeters still making him shorter than Yamato.

This life wouldn't be much easier on him in terms of food. Living on the streets would make it difficult to find food. He couldn't go to a shelter or food bank. If he did he would risk being returned to his mother. No one would believe or care about a quirkless kid when he said he was abused. Neither could he go to JP's like they had planned for him to do. In this world, Yamato wouldn't remember him. Going there would be just as productive as going to a shelter.

It hurt to think all their years together now meant nothing. No one in JP's would believe his words. Instead, they would believe him to be a madman. Yamato wouldn't have an equal to balance him out. The peace that they had created together would no longer come to pass.

Tears sprung to his eyes as he entered the bathroom and turned on the light. What he saw in the mirror made him wince. The scar across his cheek from a mishap with a Wendigo was still there. Dark bags lay under his eyes from lack of sleep. He was a lot younger than he thought was possible. By the looks of things, he was 11 or 12 just starting middle school. Looking at the Hero Analysis for the Future notebooks would give him a more exact date.

Rolling up the sleeves to his shirt he found one of his soul parent marks above his tattoo unburned for the first time since the Fall. It was that of a green falcon with golden eyes. Not that he needed protection anymore. When a soulmate or soul parent died their mark became a burn on the skin of the child or other half. Tears sprang into his eyes at the sight. He never thought he'd see the marks again.

Pulling down his shirt collar he found that his soulmate marks a black cat with red eyes and a grey scarf around its neck was still there. It wasn't unheard but it was still unusual for someone to have more than one soulmate. His second soulmate was just a little to the left of the cat. It was a black leopard with onyx eyes curled around something protectively.

Izuku had three tattoos. One took up almost all of his back. It was a Yin and Yang symbol with a koi fish in the middle. The second was in the middle of his forearm. The symbol of the Ouroboros, a snake eating its own tail. They were reminders of who he was and what he had gone through.

The only other mark was the blond falcon with light green eyes that was just below his ribs on his left side. All he knew about his marks was that the cat and the falcon were likely heroes. They had been amongst the first to die in the Fall. That was in the time that the villains focused almost solely on heroes. It was only later that they attacked anyone they could.

Sighing he released his shirt and rolled the sleeves back down. A tired sigh escaped him. He didnt want to do this alone. Yamato had promised when he joined JP's that he wouldn't be alone anymore. That his abilities would take him far in the agency. While they had then he was alone again. Without his friends or the ones, he considered his family.

Never would he have believed that he would miss Fumi and her love for experiments. Or Otome and her daily check-ups on the physical and mental health of all who worked in JP's. Or Sako who treated him less like a coworker and more like the son she never had. Or Ronaldo who wasnt apart of JP's but a detective who occasionally worked with them. When Izuku was old enough they would all go out for drinks on the quiet nights. They had been his family and nothing like the biological ones who hated him for something he couldn't control.

Shaking his head he forced aside the thoughts. First, he would focus on getting set up in this time. Then he would make a name for himself as a rogue demon tamer/vigilante. Yamato always called him, Rabbit when he was in a good mood. It was as good of a name as any.

Aizawa's POV

Nothing in the world gave him a bigger headache than dealing with vigilantes. Not even his students. It had been a good number of years since there had been a vigilante in Musutafu. Most of them kept to the more populated cities. This new one seemed to throw all preconceptions out the window.

The vigilante was called Rabbit after the green and black bunny hoodie that he wore. Those he aided said that he was short in stature but fought like a seasoned pro. It was thought that he had some kind of healing quirk as he made sure to tend to their injuries before he left.

Unconfirmed was the report that the quirk was voice-activated. Some of the victims reported hearing words such as dia for injuries and them being closed up. It was not a heal-all kind of quirk but it was perfect for first aid.

With the new vigilante came another unexpected surprise. The mark of his second soulmate burning and dark unexpected emotions coming across the bond. It was rare for a bond to form without all of the soulmate having met. It came with extreme emotional distress from one of the soulmates. Having met the first and in communication with him, he knew it had to be their third.

Tsukauchi Naomasa who was the same age as him and a detective with the Musutafu Police Department was the soulmates he knew. The man had a strong sense of justice and a kind heart. In a way, he balanced out Shouta's gruff nature.

They met when they started their respective jobs. In the beginning, they kept their relationship strictly business. It wasnt until Shouta was severely injured on the job that they agreed to give the relationship a chance.

All they really knew about their other soulmate was that he was really young. Fifteen years younger than both of them. If they wanted to meet their young soulmate it would have to be by accident. Or maybe at one of the middle school events. As one of the new teachers at UA, he was getting stuck with the job of meeting the middle school brats. The only thing that would make it worthwhile would be to meet the third. While unable to do anything more than meet with them.

Shouta's attention was drawn to the rooftop two blocks away from him. A flash in the darkness of someone moving expertly across them. It must be Rabbit again. Time to see if they could finally capture the vigilante.
