Another new chapter is here. For whatever reason whenever I get back to writing this story, I always end up with two chapters just coming out of my head. Not that you guys mind. Anyways lets get on with the chapter.

Chapter 6: A Talk of the Past

A young Katsuki with his followers were heading through the woods, he was eight years old. They were in the middle of their summer break, and were spending the day exploring the woods.

"Kacchan?" He heard a familiar boy questioned.

He turned to see Izuku and his signature curly dark green hair with a look of annoyed disgust. While Katsuki saw Izuku as more of an annoying pebble that felt the need to keep following him for reasons he couldn't understand, Izuku still saw Katsuki as something of a friend in spite of the bullying he received from the blonde.

"What are you doing here?" Izuku questioned.

"I'm supposed to be asking you that Deku. Still following me around like a lost puppy I see?" Katsuki noted.

"But I'm pretty sure I was here first." Izuku replied.

"Shut up who said you could be right?!" Katsuki shouted.

"No one!" Izuku squeaked.

"Good now stay out my way." Katsuki declared.

He and his friends went along their way. They crossed a small ravine with a creek in it by way of a down tree. As they did Izuku saw Katsuki slip and fall, like what had happened about four years ago. Izuku rushed into the creek to check on him. He saw Katsuki slowly sitting up out of the creek, rubbing the back of his head.

"Kacchan are you okay?" He asked out of concern, holding out his hand.

Katsuki instantly slapped it away.

"I was fine when it happened four years ago I'll be fine now! Don't look down at me Deku!" Katsuki shouted as he rose to his feet.

"What?! I'm… I'm just…" Izuku began before Katsuki shoved him to the ground.

"I'm someone so weak as to need help from you! Don't you dare forget Deku, your beneath me!" He declared before going to climb out of the ravine.

During this Izuku noticed the back of Katsuki's head was bleeding.

"Uhmm… Kacchan the back of your head… its ahh…" Izuku began.

"I said I was fine Deku, now leave me alone!" He shouted.

After fully climbing out of the ravine, he and his followers continued on through the forest. While they wanted to bring up Katsuki's injuries, they were too nervous due to what had happened to Izuku. Said green haired boy remained in the creek. A feeling of melancholy had come over him. Why does Kacchan hate me? I was just trying to help him. I guess we really aren't friends anymore. Izuku remained in the creek for a while letting the sorrow he felt sink in.

Elsewhere…

Nana Shimura was floating up right in darkness. She was in a deep sleep. Slowly her eyes opened.

"What the heck… I… I'm supposed to be dead." She expressed as she looked down at herself.

She examined every part of her. Doing so she saw that she was naked and possessed and ethereal form.

"I still am dead. But I'm not in the afterlife anymore." She noted.

Suddenly she felt a chill run down her non-existent spine. She turned to face something unknown. It was as if a creature of the darkness was reaching out to her. A monster whose face she could not see. She knew that it was what had dragged her out of the afterlife. She fled knowing she could not face it in her spiritual form. Tendrils of darkness came out grabbed her. They tried to pull her back, but she refused to yield. Through the strength of her will she broke free and continue to flee.

Soon the world around her became more clear. Lights which took on the form of people walked about at various levels. Nana realized she was seeing the souls of the living. The world was an empty void to her with no physical objects visible, but the soul of someone was visible. She had stopped to observe all of this, but only for a little. The monster was still hunting her and she need to flee.

She flew away as fast as she could but the monsters tendrils were slowly gaining on her. Finally, they caught her and began to drag her back. She refused to yield and continued to fight forward. Again she her will won out and she broke free, but just barely. Nana knew she wouldn't last another assault. So she kept flying in hopes of finding someway of saving herself. In that moment she saw a light bright and pure. She didn't know what compelled her, but right as the tendrils were about to grip her again, she reached out for it.

"Please… help me." She cried.

With Izuku…

It had been a while since Katsuki had left, and Izuku had remained in the creek. Suddenly he looked up to the sky. He didn't know why he did this but to him, it was as if someone up there was crying for help. He reached out his hand and felt someone grab it. He slowly brought his hands over his heart. While he could not explain it, it felt as though someone had come to abide in him.

Then a ripple went through out his body. He collapsed to his knees, his hands gripped on to his chest as an intense pain permeated throughout his body. He breathed heavy as his eyes began to dilate and sweat began to drip down his face. In the calm stream he saw his irises slowly shift from dark green to gray. He saw his eyes take on a sharper more feminine look with longer lashes. His skin became more fair, starting in his face before bleeding down across his body. A black color spread out from the roots of his hair traveling it's length to it's tips. As it did, his curls straightened out and his hair became more straight and gained a soft smooth texture. It hung down around his face, growing to a little past shoulder length. Izuku could only look on in shock as he saw his face take on a more feminine appearance, like that of a young girl.

"What's happening to me?" He questioned in a now higher pitch girly voice, earning a gasp from him when he heard it.

Soon the pain grew even more intense as his body began to shift. He cried out in pain. His body shifted into a slightly smaller more feminine form. Given his young age, it didn't change too much. However any change that did occur caused an intense pain to shoot through his being, each earning a cry. He thrashed about in the creek as pain continued to rack his body. After what felt like an eternity, the last of his masculinity faded into femininity. The newly turned girl panted as the pain finally began to subside. She slowly rose to her feet. She looked at her body with a look of shock and confusion.

"I'm… I'm a girl?" She expressed.

'Hey kid are you alright?' She heard a woman ask.

"Huh?" She expressed she looked around in confusion. "Who's there, where are you?"

'I'm right here.' The voice stated.

"Where?" Izuku asked again.

'In your head silly.' The voice again spoke.

"My head?! But how did you get there?!" Izuku questioned.

'You let me in remember?' The voice pointed out.

"Huh?" Izuku expressed.

She then remember the feeling she had before the transformation began.

"Ohhh… that was you I guess." Izuku noted. "Soooo… who are you?

'Oh right I never introduced myself. My name's Nana Shimura. It's nice to meet you.' Nana stated.

"Nice to meet you Miss. Nana, I'm Izuku Midoriya." Izuku returned.

'Two things one drop the Miss, I feel like we're gonna be stuck with each other for awhile so just Nana will be fine. And two, I think you can just talk to me in your head, you don't need to talk out loud.' Like this. 'Yeah there you go. That'll save space.' Save space? What do you… nevermind. Anyways what happened, why did you need to get in my head?

"Everyone spread out! The boss said she'd be here! The minute you find her execute her on site!" They heard a man shouted.

Izuku gasped. 'Looks like we'll have to save this conversation for later.' Wait what's going on? 'No time to explain just know that those are villains, they're probably after me. So by proxy you.'

Izuku was about to shout. 'YOU HAVE TO STAY QUIET!' She clasped her hands over her mouth. What do I do? 'You have to quietly try and escape. Preferably back to your home.' But what will I tell my mommy when I get there? 'Just worry about getting out of this forest without them finding out what you look like! I'll worry about what we'll tell your mom!' Izuku nodded. After making sure her now loosened shorts were on tighter, she slowly climbed to the top of the ravine. She peeked her head out to see who was around. She could see a few people searching through the trees. They were a pretty good distant from her, but they were directly in her path to go home.

She swallowed her fear. After looking to make sure no one was behind her, she climbed out of the ravine. She then hide behind a tree and peeked her head out. After making sure no one could see her, she moved forward a bit and hide behind another tree. She repeated this slowly moving away from the villains.

"Any sign of her yet!" She heard the man from before shout, but much closer.

Izuku gasped but quickly clasped her hands over her mouth to stop anymore sound. She slowly peaked out. Fear gripped her, right to her core. The man before her was clearly in his late twenties. He had a towering large figure that loomed over his subordinate. He wore a black german style World War Two trench coat over a white dress shirt. He also wore a pair of dark grey dress pants and black heavy boots. His hair was a short jet black and was slicked back. His back was to Izuku.

"Nothing yet Imperium Sir." One subordinate shouted.

"Well keep looking! The boss can only know the location of a bounding, he won't be able to track them afterwards." He added.

"Don't worry Sir, we'll find her." The subordinate replied.

The man nodded before beginning to turn around. Izuku's eyes widened and she quickly hid back behind the tree. The man's piercing gaze fell upon a sent of trees. The man's blood red eyes were fixated on this spot. Izuku could feel his presence smothering her. Sweet rolled down her face as she became short of breath. But she didn't dare make a sound. The man's gaze was fixated on a tree. He sent out a chain from his palm and it ripped through the bottom of the tree causing it to fall away from him. Save the scattering of a few forest creatures, nothing else happened.

"She must elsewhere." The man noted before heading along his way.

Izuku held her mouth in a vice grip to keep any sound from escaping. The tree that the man had fell was the one right next to where she was. She swallowed her fear and looked to see the man walking away from where she was hiding. Once she believed the man had gone far enough away, she double check to make sure no one was around before continuing her way out of the forest. She carefully weaved her way through the trees, being sure to remain hidden from any of the villains after her. After a long while, she finally exited the woods. Feeling she was finally out of danger, Izuku collapsed to her knees and breathed heavy.

"That was so scary." She expressed.

'I know Izuku, you did a good job out there. That wasn't easy and you were very brave.'

"Thanks…" Izuku breathed out.

After calming down she got back to her feet. Who were those guys, and why are they after us? 'I'm not entirely sure. I have some ideas. For now though you need to get back home where it'll be safe. I'll explain to the best of my abilities on the way.' Okay. Izuku got her bearings straight before heading towards her apartment. So… 'So for the record I'm supposed to be dead.' DEAD! But your in my head now! 'I'm well aware. Anyways, whoever is in charge of those guys must have a quirk that allows him to draw the souls of the dead to return to the living and binding them to someone.' That's what happened to us right? 'Yes, well… kind of… I had broken away from him and bounded with you. I think if I didn't, he'd have put me in a vessel of his choosing.' Okay but why would he do that. Does binding a soul to someone do anything special? 'Try activating [One for All].' [One for All]…

Izuku looked down on her hands and focused. Sparks of energy ran across it for a brief second. What the… 'That's[One for All], it's one of two quirks I have. Now try using [Float].' Float? 'The name of my other quirk try focusing on a feeling of weightlessness' Izuku stopped and closed her eyes. She tried to make herself feel weightless. Soon she felt as though she was floating. She peaked a bit. Then her eyes widened in surprise as she saw herself floating in the air, though not more then a few inches off the ground. She turned off her quirk and her feet plopped back on the ground. 'A bit weaker than when I had it, though that'll probably change with time and practice. But that means my hypothesis was correct. You now have access to my powers and likely can still use your own quirk.' But I am or was quirkless so how would we know. 'That'll have to stay a theory then, but in all likelihood that's why this villain's doing what he's doing.' So he's calling souls back to bind them to people to power them up. 'Essentially, yes.' But why would anyone do that unless he can control the people he binds souls to. 'That's probably the case or at the very least, causes them to be loyal to him. There's no reason he'd call back a past hero only for them to act as a distraction for his subordinates.' Yeah… I don't think I could focus on anything if someone was shouting in my head the whole time. But why try and… kill me…. Can't he just make me follow him like he does with the others? 'Probably since I broke away, he can't actually do that. He has to be the one to put them in a vessel for it to work that way. Because of this, he needed my soul to free again. I'm guessing at least.' But why would he do all of this? 'Money, power, the fun of it, there's a litany of reasons as to why he'd do such of thing.' Litanty? 'A long list of something' Oh… so how do we stop him? 'What do you mean? You're a child, you have no business getting involved in this. I'd do it myself but… I'm kind of stuck in your head.'

"But I can't just sit back and do nothing!" Izuku shouted, drawing people's attention.

She clasped her hands over her mouth. Her face turned red as people gave her weird looks.

"S-s-s-sorry, I have a sentient quirk and we were having an argument and I got a little too agitated." She explained.

Everyone looked around, shrugged it off, and went about their business. Izuku breathed out a sigh of relief. Gotta remember to keep my thoughts to myself. 'Nice save, anyways… I appreciate your desire to get involved but you don't have the legal let alone practical ability to get involved.' But there has to be something I can do! I want to be a hero! I want to help people! How can I say that at let something like this go by! The voice of Nana was silent in her head. 'Looks like I'm stuck with a real trouble maker. But your the kind of trouble maker I'd pick to hold [One for All]. If we want to do anything to stop them we'll need to train you up and get you at least a provisional hero license. In the meantime we can to some small time investigating, legally of course.' Wait so I'm… you mean I could be… 'A hero…'

Izuku couldn't stop a bright beautiful smile from forming on her face. Tears of joy began to stream down her face. She rubbed them away. She could practically feel Nana's smile beaming in her head. She arrived at her house opened her door and shouted.

"THIS IS THE BEST DAY EVER!"

"Who are you?" Inko questioned.

Izuku mind went blank, her mouth was agape slightly. Before her was her mother, looking at her in confusion.

"AAAhhhhhh…" She expressed.

Present day…

"After explaining things to my mom we were eventually able to get things squared away legally. That includes the changing of my name to Nana since Izuku isn't, and I quote my mother, 'the prettiest name for a now very pretty girl', and we went with Nana since she's now in my head, again my mom's idea." Nana explained.

"And people just went along with you just magically changing into a girl that looks almost identical to a now dead hero? And your newly acquired quirks." Aizawa questioned.

"It took some convincing. Though the fact that I look a lot like my mom now helped with that as well as distance myself from any relation to the original Nana." She added. "The quirk part was actually fairly easy. We just claimed I was a late bloomer and that my quirk had awoken a few days before my transformation. We went with the transferable one that increases my strength since it'd be harder to pin me to the original Nana with it. Some form of strength enhancement is extremely common when it comes to quirks so it's easier to wave off. The reason I'm using [Float] now is because one I don't need to worry about those after me when I'm in UA and two I have a way to explain it away when someone asks."

"I see. This all sounds a little farfetch, but it does explain how you know so much about me and my late master. It also explains why you were so hesitant to reveal anything about yourself in the times we met." All Might noted. "Also [Float] was my late master's quirk and it's function is similar to yours."

I wish I could ask if her other quirk name is [One for All], that'd basically prove that she's telling the truth without a shadow of a doubt. But Aizawa's here and he can't know of it. If she is telling the truth, her use of the term transferable quirk is likely her way of not revealing the full truth of its existence.

"It'd be nice to have Naomasa here, his quirk [Lie Detector] would help a lot in ascertaining the validity of your statements." He added.
"Such a thing is unnecessary." Nezu stated. "There are certain cues and ticks you can see when people are lying. I noticed not a single one as she was saying anything. We can at least be certain she is not lying."

"Call it a woman's intuition, but I believe she is telling us the truth." Recovery Girl added.

"What of this max power of yours though? Why are you limited in such a way? I'd expect you to have access to her full power right from the start?" Aizawa questioned.

"Our theory is that it takes time for the body to adjust to its new powers. At first I could barely muster any power. Through a lot of training we've gotten up to point it is at today. However, for a temporary amount of time I can access the full power you mentioned. To do so I either (A), do it in the quick burst you all saw during the Entrance Exam and quirk assessment, or (B), I transform into what the original Nana would look like in her prime. That's were the two minute limit I have comes in. After two minutes have past I'll be forced back into my current form." Nana explained. "If I change back at about one minute I'll be fine to keep going, but if I go beyond that I'll be bedridden. If I push myself all the way to my two minute make I'll be beridden for 24hrs."

"That's quite the limit. Far worse than my three hour limit." All Might noted.

"To be fair as I master my power, the time limit will increase exponentially." Nana added.

"I see, well at least your smart in how you use it." Aizawa stated.

"Indeed, now I do believe you mentioned you've done your own investigations into all of this." Nezu brought up.

"Yes, though the only thing I really found out is that it's likely an organization called Spiritus. Being limited to what I can do legally prevents me from really finding anything of note." Nana pointed out.

"Legal or not, you should have left it to the police." Aizawa pointed out.

"I didn't think they'd believe me at the time, not like we had much to tell them at the time, and I didn't know of this Naomasa's quirk. I also didn't want to risk exposing myself to being potentially found out by Spiritus." Nana explained.

"A fair point… Since they are after your life, I can see why you'd want to make sure the truth of your change doesn't get out." All Might noted.

"But that brings us to the main question. What now?" Recovery Girl pointed out. "Spiritus may already be known to the police and heroes. But none of us expected them to be up to this."

"True, and there's also the fact that we have other villain factions likely popping up due to those who have also broken away." All Might added. "The country could be filled with super powered villains with multiple quirks and a second mind helping them along the way."

"If we are to fight such a threat. Then we must match these 'Bonded' with our own." Nezu noted. "Have you met any looking to become heroes like yourself yet Midoriya?"

Nana shook her head.

"Not yet, heck I've yet to really met a villain who is, as you say, a 'Bonded'. As far as I know I'm the only…" She began.

Suddenly there was a knock on the door. Before anyone could respond, the door slowly opened and in stepped a red haired boy Nana recognized from class.

"Sorry to eavesdrop, but I want to make sure she wasn't with the villains." The boy stated "But I didn't come in to say that, names Eijiro Kirishima and both Crimson Riot and I are ready and willing to help."

And that's a wrap. Hoped you all enjoyed Nana's origins. Have a Merry Christmas and a Happy New Year. Til next time.
