That time I was reborn as a warrior princess

Chapter 16- Byleth's story

Katsuki was putting the last of his stuff in a box before closing it. His father, Masaru, was helping him with the moving. Katsuki returned the apartment's keys to his father after finishing to put his things away.

"I bet you're happy to have your place back, old man." Katsuki comments a bit cold

"Well, I can not lie, I've missed my little piece of heaven." Says Masaru a little nervous

Both of them fell silent. They have no subject to talk about. Katsuki was praying that the van he had rented would arrive there soon. Katsuki was not surprised that his mother had not visited him at hospital after the dragon's attack and his father, the coward he was, had not visited him either until he was discharged. It was very awkward for both of them to be in the apartment together

Byleth only looks at both male Bakugou in frustration; she can see Bakugou Masaru can be as stubborn as Katsuki. The spirit can understand how Masaru must be feeling towards Katsuki after his bullying actions were revealed. She did feel the same thing towards Edelgard back from her realm.

Edelgard's ambitions killed thousands of people during the Fódlan Wars. Though she understood her former student for wanting to destroy the caste system and the culture of the crests, she could never forgive her for murdering thousands of innocents for this. And worse, she turned innocent people into dark beasts for her objectives and she never regretted none of her atrocities. Edelgard was even willing to kill those who were against her ideals without any mercy. Byleth was happy for her being the one to end Edelgard's life instead of Dimitri. Dimitri had suffered enough because of the actions of the Black Eagle leader.

Unlike Edelgard, Katsuki regrets his actions and he is trying to change to be a better person.

"So, when will you two divorce?" Katsuki asks, breaking the silence.

"What do you mean?"

Masaru tried to play dub. But Katsuki could see this through and he tsked in annoyance.

"Don't fucking play dumb, old man. I know you and the old hag are having problems in your marriage. Ever since Izuku's death and Auntie Inko breaking her friendship with her, Mom is becoming very unbearable to you." Katsuki says, crossing his arms, while avoiding to look at his father " I understand you're submissive and you're the only one who supports her, but even the saints have their limits. And I bet you're already at your breaking point."

Masaru sighs tirely. He hates whenever he is so easy for his son to read him. He admits he already has the divorce papers; he is just waiting for the right moment to ask Mitsuki for divorce. Ever since Izuku's funeral, Mitsuki has changed; she is angier and very unbearable. Masaru admits that lately she has been very verbally abusive to him, which shocked Katsuki greatly. He knew his mother was not an easy person to deal with but she never was abusive to his father. He wonders how bad things have gotten since he was kicked out.

"I did not say anything because I did not want you blaming himself for this too. You needed this place more than I did. But like you've said, I am reaching my breaking point."

"Dad…"

"I am also to blame for the way you've become, Katsuki. If I had paid more attention to your actions, if I had involved more into your life and not leaving your mother to solely take care of you and your education, maybe none of this had happened." Then, he looked at his son as he placed his hand on his right shoulder. "I am proud to see you're regretting your past actions and you're trying to change yourself to be a better person. Not many have the courage to admit they are wrong in their actions."

Katsuki avoided his father's eyes. He did not deserve his father's compassion. Then his phone vibrated; it was the van. They took all the boxes and put them all in the van. Before getting in the van, Masaru gave Katsuki a card. Katsuki was surprised to see it was a business card for a store specializing in glass eyes. He looked at his father, confused.

"It is just in case if you do not want to use the eyepatch." he says, smiling.

Katsuki could not help but smirk,

"What are you talking about, old man? The eyepatch makes me look more badass!" with that said goodbye to his father he got in the van. When the van drove away, a tear rolled down from his left eye.

Lucina and her group were surprised how big the dorms are and how they were able to finish them so fast. And she was surprised that some of her classmates also decided to move the dorms as well and they are Uraraka, Kirishima, Ashido, Tsuyu, Kaminari and Bakugou.

Speaking in Bakugou, they were summoned to Principal Nedzu's office and there they could see Aizawa was there as well. Lucina had to explain to Laurent, Gerome, Noire and Yarne about Byleth's existence to them. Laurent was fascinated since it was rare to see a person with two souls and Gerome, he told them he did not trust Byleth. Lucina could not blame him since they do not know anything about Byleth. Bakugou allowed Byleth to possess his body. They could see Bakugou's remaining eye was green instead of red.

"So are you Byleth? Lucina told us about you and I want to ask this: are you a friend or an enemy?" asks Nedzu right to the point.

"You don't need not be afraid, little one. I only care for Katsuki's well being and nothing more. I have been with Katsuki since he was born." Byleth says.

Lucina still finds it very weird to see Katsuki sounding so calm and serene.

"From what Lucina had told us, she felt some mana energy from you." Laurent comments " You came from our world, didn't you?"

"I admit I came from another world but not from your world. It will be easier to show you my memories."

Then, a symbol appears on Katsuki's forehead. Lucina recognizes the symbol, it is the same one she saw when Bakugou saved her and the others from the rubbles and it was that moment she felt some mana energy from him.

Suddenly they found themselves somewhere else. Byleth told them that the place they were in was the Garreg Mach Monastery. They even could see a woman in white and blue robes. She had long green hair and eyes and she was using a crown.

"That woman is Lady Rhea, she is the archbishop of the church of Serios." Byleth says. Then, she saw a young woman wearing in black. She had turquoise eyes and hair. " That woman before Lady Rhea is me, before being reborn into Katsuki."

"Is that you?" Aizawa asked. "You were just a kid back then."

Byleth explains before going to the Garreg Mach Monastery, she lived with her father in their mercenary group, doing some odd jobs around Fodlán. One day, they saved three young students from the Officers Academy. They saw Dimitri, Edelgard and Claude. Nedzu comments that the Officers Academy reminds him of the UA. Byleth comments in a way the Officers Academy was Fodlan's UA .

Then, they heard Reah, a green haired guy named Seteth explaining about the academy three houses and how each of them represents a different nation. The blue Lions represents the ones from The Holy Kingdom of Faerghus, the golden deer represents the one from The Leicester Alliance and the Black Eagles represents the ones from Adrestian Empire. The group was shocked when Rhea asked Byleth to work there as a teacher for one of the three houses.

"She is kidding, right?" Aizawa asks, shocked "You seem to be almost the same age as those kids from the academy.

"Seteth said the same thing." Byleth comments, chuckling a little. In her point of view, Aizawa was a bit similar to Seteth " I was shocked as well cause I had no experience in teaching. I may have experience with fighting and battles because of my mercenary life but never teaching. And I accepted anyway because I've liked the idea of living in a single place for once and having good meals everyday. I ended up being the teacher for the Blue Lions house. I can't explain but I felt a connection with the house leader, Dimitri."

Then, Byleth showed all the members of the Blue Lions. The heir prince of the kingdom Dimitri. The red haired boy named Sylvain, a raven haired young man named Felix, a young boy with gray eyes and hair named Ashe, the gentle young woman named Mercedes, the fierce blond girl on a pegasus named Ingrid and the final member of the group was a young girl with orange hair named Annette and a big muscled guy named Dedue.

"We shared good and bad moments." Byleth says in a sad and soft voice

Byleth showed them how she started her classes and how she trained them. She showed how she gained her sword, the Sword of The Creator. Lucina commented that the sword, in a way, reminds her own sword Falchion. She showed how the Lance of Ruin ,a powerful weapon very similar to the Sword of Sreator that turned Sylvain's brother into a dark beast. They were horrified at the sight and how she and the blue lions were forced to kill him. She showed them Dedue and her cultivating flowers while talking about them. Having tea time with other students, how she was forced to execute Ashe's adoptive father, and the academy hosting a ball. They saw Claude, the leader of the Golden Deer house taking Byleth to dance. The death of her father and how she fused with Sothis in order for her to get out from the dark dimension, turning her hair and eyes into green color. Lucina now understood why she felt mana and divine energy when Byleth possessed Bakugou's body on that day, Bakugou had some powers of Sothis and Byleth inside him when he saved her and others from the rubbles.

"Things were turning complicated on each moon. Traitors everywhere, conspiracy and I really started to doubt about Rhea. However everything changed when one of the students revealed their true colors."

The scenery changed to a scene that looked like an underground tomb. A masked armored person attacked. Byleth attacked them and destroyed their mask revealing the face of the enemy; It was Edelgard- the house leader of the Black Eagles. They were shocked how isane Dimitri has become after the revelation.

The empire attacked the monastery. The group were shocked to see Reah has become a huge white dragon while attacking the army and the dark beasts.

"Wait, is Rhea a divine dragon?" Laurent asks in shock.

"Rhea is a sky dragon from what I can remember." Byleth says " She is not a manakete since she had no dragon stone with her. However, the attack on the monastery was awful and I fell into a cliff. I dunno how but I survive from the fall and I was asleep for five years."

Byleth showed how unstable Dimitri had become after five years. But fortuanity, all the Blue Lions were reunited. They managed to defeat the empire army and formed an alliance with Claude and the Leicester Alliance. They saw the final battle against Edelgard and how she turned herself into a monster by using the crest stones. Even being defeated, Edelgard still tried to kill Dimitru but Byleth stepped in and killed her instead, cutting her head off.

"But things did not stop with Edelgard's death. We found out about the true enemy behind the curtains; they were called Those Who Slither in the Dark. They were a mysterious faction led by Thales."

Byleth showed Thales and his allies. She explains that Thales and his group were the enemies of the church and the ones responsible for the death of Sothis and Rhea's kin, forging the hero relics from their bones. The group was horrified by this information. And she also explained how they used the technology from an old era to revive Nemesis and the Ten elites. She told them that The kingdom of Faerghus and The Leicester Alliance had joined forces to fight against the undead army.

"It was a terrible battle. Some lost their lives " They were horrified when they saw Felix, Leone and Silvain being killed by the undead army. "I fought Nemesis myself but he had a dark version of Sword of The Creator with him. Claude managed to kill him with his own Heroes' Relic, the Failnaught, while I used the true Sword of The Creator to destroy the dark sword. But by doing this I've created a black hole which I was sucked into. It was the last time I saw Dimitri and the others."

They all Byleth being sucked by the black hole while Dimitri were trying to reach for her but Clauded and Dedue hold him back. Then, the group saw Byleth being rescued by a small japanese village. From the villagers' clothes, Aizawa and Nedzu imagined Byleth must have arrived around the japanese feudal era. Byleth mentioned she was thankful for the villagers having taught her their language and giving her shelter. In exchange for their kindness, she protected the village from bandits, nobles and an army of samurai that wanted to destroy the village by order from their lord. They were even shocked when Byleth showed she had fought with Oda Nobunaga himself. After showing everything they needed to know, Byleth returned them to Nedzu's office.

"I am sorry for what happened to you, Miss Byleth." Yarne says with sadness in his voice " I know how war can mess people up and how you ended here."

"But there is something that is bothering me." Gerome comments, a bit concerned. " That Heroes' relic, the Sword of The Creator, was with you when you ended into this world, right? We saw what happens when people without crests try to use those weapons. What happened to the sword after you ended up in that village?"

"I asked the villagers when my death came, they have to hide my sword somewhere that no one can find it. I warned them what happens to those who try to use the Sword of The Creator without the goddess' gift. I dunno where the villagers hid the sword after my death but I think they did a good job hiding it since there are no dark beasts running around here, right?"

She was right. If the sword was found and being used, they would have evidences of dark beasts' attacks. Gerome asked Lucina if they should find the sword. From what he could tell, the Sword of The Creator was as powerful as Falchion. Lucina shook her head.

"I admit the sword could be useful against Grima but I think it's best to remain hidden." Says Lucina. " From what I could see, only Bakugou here has the possibility to use the sword without turning into a dark beasts since he has the Crest of Flames, Am I right, Byleth?"

She frowns at the possessed Bakugou. Byleth only stares at her with an emotionless expression.

"Yes, he has the crest of Flames, just like I had in the past." she confirmed. Katsuki was surprised, he had no idea he had such a thing inside of him.

"Hum… I think Lucina's right. I also think keeping the sword hidden is a wise decision." Nedzu says " The heroes commission has their eyes on you, Lucina-san. They tried to take your sword away while you were in the hospital."

Lucina and her group were shocked by this news. Lucina exclaimed how come none of them had warned her about this. Nedzu raised his paw, siling her.

"Don't worry, I´ve used the witness program's card against them; they can not touch you or your things as long as you're under our protection. They backed off, but I don't know for how long."

Lucina groans in frustration. That's what she needed: the heroes commission is now watching her and it was not a good thing! When she was Izuku, she had heard some shady rumors about them and how they couldn take some children with certain quirks to turn them into their personal soldier children. If they are not careful, the hero commission could turn their enemies.

At the heroes commission building, an old woman looked with cold eyes to the young man with wings in the front of her desk.

"Are you sure you heard right, Hawks?"

The young man was Hawks. Hawks was their most loyal agent and the only one the commission trusted.

"Yes, from what I was able to hear, that girl, Lucina Ylisse, knows who was behind the dragon's attack and she is afraid there will be more dragons' attack in the future as long this villain, that she calls Grima, is on the loose. And from what I could understand, he was also responsible for the massacre at Best Jeanist's agency."

Hawks, the number 3 hero, was at the hospital visiting Best Jeanist when he eavesdropped on the conversation between Lucina and Ingenium thanks to the ability he has on his wings. Except for the reincarnation and being from another world thing, Hawks had reported everything to his boss.

The woman sighed in frustration. She watched the video of the dragon's attack again and again and she could see the only thing that truly stopped was the girl's sword. If it wasn't for that rat, Nedzu, they would have confiscated the girl's sword to examine it.

"Hawks, your next mission is to keep your eyes on this girl. Find anything relevant in order to stop this Grima. Grima may be an even bigger threat than the League of Villains."

End of the chapter

A/n; And that's the chapter 16.

Are you surprised that it was Hawks who heard the conversation between Tensei and Lucina?

I bet none you had expected that.

As for Byleth's past, I love the route of Blue lions, they are my favorite characters. But I admit the Golden Deer's rote has the true ending. So I decided to mix both the routes for Byleth's past before she ended up in the BNHA world.

And do not worry, the Sword of The Creator will not stay hidden for very long.

I admit the chapter is kinda boring but I hope you still enjoy it anyway.

Do not forget to leave kudos and comments. They make me write more and more.

Suggestions are also welcome.

See ya all in the next chapter!
