{Father's POV}
*Ugh... My head, that brat...*
"So... I lost. I didn't expect that move." He says whilst looking up to an unfami- Wait it's his bedroom...
"You enjoy sneak attacks so I did just that." A voice came from the seat beside my bed.
"Finally awake?" She asks me.
"So I guess I have to agree to your request. I didn't think you could beat me. Your ability is stronger than most individuals in the top 10 hero ranking. You could probably be in the top 5 or higher already." I say with full confidence in her. I may not be able to compete with All Might and I don't know my chances with Endeavor but if she can beat me... She is definitely strong enough to handle her own. As I look at her I notice her orange eye. She hasn't mentioned it yet. It must be an extension of her quirk. Does she not know about it? I hold myself back from pointing it out so that if she does notice she's gonna freak the hell out.
"I don't really care about rankings. But I'm happy you held up your end of the deal." Sana says with a massive smile on her face. I guess she really just wants to be a Hero...
"I'll let you get into U.A but I'm not getting you a recommendation."
"Naturally."
"Mhm, if you don't get first on the ranking I'll be disappointed. Once you get into U.A, I don't care whether you follow the rules. You are my daughter and if anyone dare makes you do something you don't want to do, I'll destroy them." I say, whilst thinking if they actually dare question my authority.
"Heh. So I can wear the hoodie?"
"I wasn't able to stop you before was I? Sure. Just keep your hand out of your pockets." ... It's an incredible rude habit, I wonder if there was any point to teaching her etiquette now.
"Fine, I do have a favor though."
*Sigh...* "What do you want?" She makes too many requests lately...
"If both Toga and I, manage to get in, I want to be in the same class."
"That's it really? Fine. But your paying for the building you demolished out of your allowance."
"Tsk" She says, looking away. Did... Did she really just Tsk me?
"Don't *Tsk* me. Please be safe, Oh by the way, what is your relationship with th-"
"BYE DAD!" She shouts whilst running away, keeping me from finishing my question...
... Damn brat.
...
{Sana POV}
"Miko-chaaan? You in here?"
"Come in!!" As she said that, I opened the door to see 3 tubs of Cherry Garcia around her. She quickly rushed and jumped at me as I opened the door causing me to fall over.
"Sorry for being away for a while, I've been with my Father for the time being. I feel slightly guilty about beating him up so bad."
"So you won?! We can go to U.A together?
"Heh, yeah. Thank you for believing in me." I say with a happy expression. No normal person would believe that an 11 year old could beat 'the Emperor of Japan' but she still believed in me anyway.
"..."
"What is it?"
"Your eye, why is it orange?"
*Wait, it finally combined? Why didn't Father say anything? Did it just happen* Endlessly questions fill my mind.
[Kid don't think about it too much.]
*Fine...*
"Oh... That. Well... let me explain something first, I uh have a gift for you. I've been holding it on to her for a while."
"Her? Did you get me a puppy?" She says with an excited an expression on her face.
"No, no. Heh, first I need to explain to you about how souls work."
"Awh, wait Souls?" She asks with a dejected expression.
"Yeah, I can't really explain the rest right now because it might be a bit too much to process, so you'll have to wait for me on the rest. Souls, are the Culmination of our being. Everyone has a soul and they have different colors linking to our character. Now there is a thing called Magic. Magic is the ability to use our soul to produce different types of abilities, similar to quirks. Humans can't use this magic, however if you get your hands on a soul that can. You will be able to have power that doesn't compare to others." Sana says as she holds Toriel's soul out. It was a white upside down soul, floating in the air.
"This is... a good friend of mine. Her soul doesn't have a body anymore, meaning that she can't see, hear or know of our existence, she can just resonate with other souls. Which is why I want you to have hers. As I said before, your quirk may be viewed as evil. With Toriel's power you can prove to others you can handle your own. By absorbing her soul, you won't get any memories or side effects but you will get her magic." Sana says reminding her of when she spoke to Sans about it.
...
[Kid. There although I hate to say it, you won't be able to bring her into the normal world, there is no way for a Soul to regain their lost memories once they move to a different body. The only reason this system is able to is because it analyzes it completely, if her soul is put into a new body, her memories are reset. All her memories as of now have been copied to the system, similar to Paps. I'm just glad the system copied his soul before you managed to absorb it.]
...
"So your saying if I somehow absorb this 'Soul' I would get extra powers?"
"Exactly, it's the same powers I have now. The souls I have in my body are called Sans and Papyrus. Sans, well he's a bit special and Papyrus is in a sense my Brother."
"Wha?"
"As I said I'll explain it later."
"So why don't you absorb these souls? You didn't need to tell me anything." She says with an extremely hesitate tone. She must be thinking why her? Even when that question is obvious.
"That's because I trust and like the hell out of you and it's also the only way to explain my orange eye without lying to you."
"I... don't know." She says hesitantly.
"What?"
"Well it's your friends soul. You would want to be with her wouldn't you, why would you give her to me? She would just be wasted on me."
"... She wouldn't be wasted on you. I want you to be safe. You're quirk doesn't represent you, I want you to be able to take to offensive measures instead of being the one getting hurt. You don't deserve that" Every time I see her, hurt... It crushes me. Over the past 6 years she has been getting bullied more and more for letting her personality out more and because I'm not constantly around to protect her, she can't do anything about it.
"..."
"And besides, the magic of this soul allows the user to produce FIRE, so its perfect for you!" I say in a confident tone, to lighten up the mood.
"Huh, Why?"
"Because your pretty h-hot already..." I say as I look up to Toga who is still on top of me. Causing her to frantically back away...
"Th-Thanks." She says with an extremely awkward tone whilst covering up her rosy cheeks.
"... A-and so, that's why I want you to have her soul. Using a soul isn't like how we use our quirks."
"You make it sounds like determination is a super power or something."
"..."
"Really?" She said with a dead pan expression. I would have the same reaction, Determination is basically the ability to not give up. How can you turn that into an ability to hop timelines, worlds or to stop and reset time? It's stupid.
"... I'll do it." She says with a... determined expression?
"Then, just hold her soul next to your chest."
She does as I say and when she does, she makes a soft smile.
"It's very warm..."
"Was... Was that a pun?" I say with shock and disbelief, even to the point of holding my hands over my mouth. I'm so proud...
"No! I can't explain it, it just feels really nice. Her soul is very warm." Himiko says as the soul begins to disappear, merging into Himiko's body.
"I'm glad you decided to accept her. I will tell you everything soon but first, we should get your story straight, incase they ask you about your two 'quirks'"
"Right..."
"How can you connect transformations and blood to fire magic..."
"... I have no idea." She says whilst scratching the back of her head.

That question was designed for the comments. Please help find an excuse. Pretty please?
Also. If you can't tell, I retconned Toriel. I basically made it so her soul would be in her inventory. After hearing some comments, I decided rather than give papyrus's soul but give her Toriel's soul. Because Sans lava her. I also made it so Sana absorbed Papyrus's soul, giving her a major jump in her abilities.
