This Chapter is my take of Belletiger_BT's 'That Time I Got Reicarnated as A Warrior Princess' first chapter as it inspired me as well but more centered around Lucina/Izuku's confrontation with his/her past with a slightly original storyline. Check the original story before this one and give the author some love for a very interseting concept!

Izuku was tired. Very tired. He was slowly going up the stairs towards the rooftop of an abandoned building. Today was his last straw. His heart was broken in pieces thanks to All Might's words. He just wanted to end it all. He didn't want to continue living like this, continue suffering just because he was born different in a super power society. In a society where men aren't equal and a four year old would notice it quickly than everyone else in the world.

"If you want a quirk so badly, throw yourself off the roof and hope you'll be born with one in your next life."

Kacchan's words continued to echo in his mind as he reached his destination. He went to the edge of the rooftop, looking down. He thought about his mom, he knew she would be devastated from his death but he thought it was the best for everyone. That way she would not continue to suffer because of him anymore and she would move on with her life together with his dad. He took one deep breath before he stepped off the edge.

First came a hard hit from having fallen on the hard concrete below and the pain numbing everything. After a few seconds, there was no pain.

He was finally free.

By the time Izuku opened his eyes again, he was floating in a dark void. He wasn't surprised, he had just committed suicide after all. He had heard of souls who committed suicide don't go to heaven or hell. Izuku wondered if this was purgatory, the place between the two to be judged. It didn't matter, he was finally free from his miserable life even if he took the easy way out of it. It didn't matter.

"You poor child." Ringed a powerful and yet kind voice from the darkness.

Suddenly, a woman with long green hair and gentle green eyes appeared before him. She gently took Izuku in her hands, smiling softly to him as he laid in her lap. Izuku was amazed. He could not speak or move. He felt as if he was in the presence of a beautiful goddess.

"Poor little child, you've suffered so much for something beyond your control. I can even see the many scars in your soul." She pointed out sadly, gently brushing away some of his green locks from his face.

"Who are you?" He asked in awe.

"I've been called by many names, I've even been called a Goddess. But you may call me Naga." She says, smiling. "It is very rare for a soul like you to come from another world and come to my realm." Izuku looked at her confused, what did she mean with 'a soul from another world'? "But I can see you're a very special soul. I am very lucky to have you, here, in my realm."

"What do you mean, ma'am?" Izuku asked, confused.

Naga slowly explained that there were many realms outside of his own and sometimes, souls can crossover to these other realms to be reborn and maybe start a new life away from their home realms. Sometimes, even the gods themselves become interested in these crossing souls just like Izuku.

"I can make you be reborn in the realm which I protect. You will be able to start it all over again."

Izuku only looked at the green haired goddess in realization. Starting over? Will he finally be able to have a quirk? Will he finally be a hero like he wanted? But what if the realm Naga was talking about had people over there who didn't have quirks? But there is a question which Izuku thought was the most important one out of all of them.

"W-Will I be happy?" He asked. Naga only looked at him with a gentle smile.

"Being reborn, you will start your life all over again. You will go through moments of joy, sadness, hate, love, empathy and many other emotions just like your previous life. However, unlike in your past life, you will have a family who'll truly support you and love you to the bitter end."

"T-then I accept."

Suddenly, Izuku was blinded by a strong light, Naga disappearing from view. He cried out as he felt his body was being taken away by a powerful water stream. Then everything went dark. When he opened his eyes, he felt his body was smaller but he felt so warm and unmovable. He was also wrapped in a cozy blanket. Looking up, he saw a woman. Her face was covered with sweat and she looked very tired but very happy. She had curly brown hair and gentle brown eyes of the same color while dressed in a thin white gown.

"Look Chrom, isn't she beautiful? She looks so much like you." the gentle woman said as she looked at him with happiness.

Then, Izuku looked at a man with dark blue hair and eyes coming to the woman's side, a strange mark on his right shoulder. Just like the woman, his face was full of joy and pride. His strong arms wrapped around his small body; where he felt safe and protected.

"Welcome to the world, our daughter. Our little Lucina." Izuku couldn't help but smile at what he believes to be his new name and identity. His, no, her new parents were overjoyed to see her smile.

Since she was a child, Lucina always knew she was different from the other children. How different was she? Well, she remembered everything from her past life, when she lived as Midoriya Izuku. Lucina thought her situation was very odd; she feels like she was in those old isekai novels that her past mother, Inko, used to love to read. In this medieval world, Lucina noticed something during her childhood that everyone didn't have quirks, everyone that lived here were quirkless just like how Izuku was. But, they had something much better than quirks; they had magic. Real magic that could bend the laws of physics through the use of tomes and spells.

And in her new home world, Lucina had a whole family, a father, a mother and, some time later, a little sister. Don't get her wrong, Lucina knew how much Inko loved Izuku but unlike her old mother, her new mother, Sumia, gave her all the support she needed to follow her dreams instead of apologizing over and over again for something Izuku had no power over.

Sumia was a bit clumsy. But she was very kind and an amazing mother to her children and everybody that knew her loved her the way she was. She was the one who gave Lucina her tiara, something she wore constantly as the red sneakers that Izuku always wore. She also had a natural talent to tame and calm animals. Even horses that her godfather, Frederick, could not tame was quickly quelled by Sumia.

Chrom was a very present father. For the better or worse, he was always there for his wife and children. Chrom loved Lucina very much, teaching her how to fight with swords, lances and fire arrows, teaching her about politics, laws and everything a crown princess needed to know since one day she will become the new Exalt of the Halidom of Ylisse and the next wilder of the legendary sword Falchion. A sword that had been passed down their bloodline since the day the First Exalt was given the sword in the first place, Lucina's ancestry was something she was extremely proud of having and wanted to live up to their legacy.

Cynthia was her little sister and most of the time, she needed help since Cynthia had a habit of getting herself in trouble because of her clumsiness and naiveness. But just like Lucina, Cynthia wanted to be a hero just like their parents and Lucina was helping her to reach her dreams, unlike certain people back from her original world. It felt great to have a sibling to talk to since Izuku was an only child and it was rather lonely with only a mother to be around during his childhood.

Lucina was also friends of her father's special group, the Shepherds, and their children. However, she had a close friendship with Gerome.

Gerome was the son of Cherche of the wyvern riders squad. Though being shy and using a mask to help him with his insecurities, Gerome had a great passion and love for wyverns. He even took Lucina to see some baby wyverns hatching once. Gerome's dream was to be a great wyvern rider just like his mother. Gerome was Lucina's very best friend.

Lucina also had a close relationship with Robin, her father's best friend and the kingdom's best tactician. Robin was also Lucina's mentor. It was from him Lucina learned how to fight with magic and swordplay at the same time. Lucina would have become a great tactician like her tutor but for personal reasons, Lucina decided to be a lord class fighter instead even if she would make a great tactician. Robin didn't judge her decision at all as he knew how much the little girl adored her father and was like an uncle figure to little Lucina.

Lucina's happiness soon became sorrow, angst and horror when the Fell dragon, Grima, attacked. Her parents were killed in action while protecting the kingdom. The only things left of them was the legendary sword, Falchion, and the tiara on her head. Lucina tried to awaken the sword's true powers but one of the gems of the Fire Emblem was stolen and broken. The awakening was impossible, her beloved home was doomed.

Fortunately, the dragon goddess, Naga, gave her a solution; to go back in time and stop Grima and his loyal subjects from gaining power and stopping the war before it even started. However, there was a problem: it was a one way trip. If they go back in time, they might not be able to return to their own timeline.

It was a difficult decision but Lucina was determined to stop the war and save her family and friends from death. However, she wasn't sure whether or not her shepherd group shared the same feelings as her. But to her surprise, even knowing the sacrifices they have to make, the group decided to go to the past with her anyway.

However. When they all went into the portal, they were divided by the interruption of Grima finding out about their plan and had to come to terms with it until they were reunited again. Lucina had arrived just in time to save a young Aunt Lissa from a Risen, securing that Lissa would be okay and together with her young father's group, repelled the Risen from the area. But facing her father after so many years alone to fight for what's left of her home, Lucina just wanted to run over to him to cry in happiness for being alive but with the mask over her eyes to hide her heritage to keep her identity as his daughter a secret to not change the past too much from the start.

Lucina introduced herself as 'Marth', after the Hero King she admired to give herself strength, and was surprised that they hadn't figured out that she was a woman with her poor acting. Either they could be easily dumbfounded when they were younger, or her overall appearance made them assume she was a man at first glance. After all, her clothing was more boyish in appearance and she didn't really care about looking pretty or have a more feminine frame as other women. She felt it was a nod to her previous life as Izuku, even though she buried everything about that life except her former identity and her last moments as him, though some of his personality comes through at times.

After leaving her father and the others, Lucina had taken a long moment to steady herself and after minutes of crying that she had arrived in time to save her dear aunt and help those that had protected her. Soon enough, she started to help her father and his friends from the shadows and dueled against them later on. But the most nervous moment was on the night that was supposed to be her late aunt Emmeryn's assasination, an assassin managed to destroy her mask, revealing her true appearance and her actually long blue hair visible to Chrom and Robin. She was glad that it was dark so the two didn't see the Brand in her left eye and the moment being cut short with the stopping of the assassination of Emmeryn.

It was successful and the current Exalt was saved. Lucina was left wandering around in an attempt to find her comrades but after Emmeryn was kidnapped some time later, Lucina witnessed Emmeryn falling down the cliff and sacrificing herself for her people. That moment triggered the memory of Izuku's suicide. They popped up in her head instantly and the adrenaline almost made her want to vomit from the panic and fear, almost re-feeling the short but massive pain she had felt after the fall. What's worse, the future she wanted to save was back on the path of destruction.

However, during the two years that Lucina went into hiding, she felt a sensation. That was the sign that her present self had been born, which had calmed her a bit that her existence was still there. Lucina could only hope that her present self doesn't go through the same thing that she did.

Some time later, Lucina's emotions got the better of her and blew the cover she had carefully created. When protecting her father from an enemy, Lucina had accidentally called Chrom 'father'. But she didn't regret her mistake. Chrom accepted her as his daughter much the same and Sumia did as well, though she was a bit reluctant to trust them at the start and had suspected that Chrom was cheating on her.

After being reunited somewhat, they started to do what Lucina had planned to do from the beginning. Find all the Gleamstones to complete the Fire Emblem and defeat Grima once and for all with Chrom's Falchion. On the way, Lucina was slowly reunited with Cynthia and their friends during their travels and they got to meet their own parents when they were young.

Lucina started her uncle-like relationship with Robin again, but it was almost ruined when Grima managed to control Robin's actions. He not only stole the complete Fire Emblem but Lucina found out the truth of how her version of Chrom fell in battle. Robin killed his close friend when he was possessed the second time. She knew that someone close to her father was the one who killed him but knowing it was a possessed Robin that did it, Lucina started to regret ever trusting her future mentor. However, when the pretty much alive Basilio came as well, Chrom stood up with his small wound and the three men revealed that Robin knew exactly what'll happen long before they came to the Dragon's table and devised a plan to trick Validar at his own game.

In the end, the future Grima, having taken the form of Robin, managed to revive his present self and after a hard battle, Robin sacrificed his existence to protect his friends and close ones in order to kill Grima so it would never return. In the present or the future. Naga explained to the Shepherds that Robin might return one day thanks to the close bonds he had made with all of them. On that day, everyone searched and waited for Robin's return.

Lucina was happy to see that the future was now being rewritten and in good hands, they've changed their fates together. Lucina managed to snuck inside the castle to visit her present self, knowing that Izuku had just been reborn in the present in this world as well. Wishing the best for her infant self, Lucina left without a trace except a letter to her parents and another to her infant self, words that she wanted to pass down as a message.

Since then, Lucina travels to find a new purpose as her friends slowly return to the future, merging with their new future even if they'll still have the memories of their previous life.

What Lucina didn't know was that she had to face her painful past as Izuku Midoriya soon, sooner than she was ever prepared for.
