I think I forgot to mention that the previous versions of this story are named 'Daughter of a genius' (though with a 'Rewrite' in front of the second version). I just didn't want to use the same name again!

Tony's full name in this story is Anthony Edward Stark (A. E. Stark as you would see it under the Ironman section).

Kagome's mother will be known as 'mama Higurashi' as I can't figure out if she was actually given a name in the series.

Warning! There will be cussing in this story!

I do not have a beta to proofread for me so if you catch any mistakes then please point them out to me! (I know that I suck at catching them myself as I, sort of, read myself blind in my quest at finding mistakes)

Kagome had always known that her mother had secrets, though she never knew that it was a big or important secret.

One thing that had never been a secret was that Kagome and Sota did not share the same father. It had never been a secret who Sota's father was, however she always evaded any and all questions about Kagome's father - she was rather good at it as well, surprisingly so, in fact.

Mama Higurashi had contemplated telling Kagome about her father when the well had closed, though her fear of it being the wrong time to do so had always stopped her from saying anything.

It was only after Sesshomaru had confronted her about it that she began contemplating the issue again. She was fairly sure that he would tell Kagome himself if she did not do it.

So mama Higurashi began contemplating just how to tell her children about Kagome's very famous father, how she would make sure that they would keep quiet about it and how she could arrange for Kagome to visit her father before too long as she figured her daughter would benefit from getting out of Japan for a while.

So she set about arranging everything so it would all be ready for the 'big reveal'. She got some help from Sesshomaru who made sure to arrange a plane – yes, Sesshomaru did, in fact, own several planes – and a place for the young lady to stay at during her visit.

He also made sure to set Kagome up with a phone so she would be able to get into contact with someone if things went south with her father, though he strongly doubted it would do so.

(/#¤#\)-(/#¤#\)-(/#¤#\)-(/#¤#\)-(/#¤#\)-(/#¤#\)-(/#¤#\)

It was when everything was ready that mama Higurashi had sat Sota and Kagome down in the living room. Her children were sitting side by side on the overly squishy couch while she was sitting in an old rocking chair that made ominous creaking sounds when one rocked in it but had too many good memories attached to it for her to stomach throwing it out.

Mama Higurashi took a deep breath, trying to figure out how to start the conversation, worrying her children further than they might have been before.

"You know how I never told you the name of Kagome's father yes?" she started, looking at her children seriously, wanting them to know that she was going to tell them something important, that this was not a joking matter and that she was going to reveal something that had always been a big secret in the household.

Neither Kagome not Sota had ever understood why the identity of Kagome's father had been such a big, very important secret – though they had always felt that their mother must have had a very good reason to keep that secret just that.

"Kagome's father is a very important and famous man," she continued, looking from Kagome to Sota to make sure they were listening attentively. "His name it Anthony Edward Stark, more commonly known as Tony stark." She said, taking a deep breath, still looking at her now wide-eyed children.

"I… My… What?" Kagome stammered, her eyes wide and stunned, her little brother was no better as he sat looking from their mother to Kagome, his eyes wide open and gaping.

"That's so cool." He whispered; his voice full of awe. Of course, Sota was a fan of Tony, he had been that since the man had made weapons but had become even more of a fan after the man had become Ironman.

"It… Wasn't planned at all, we didn't know each other and we were both very drunk when it happened," Mama Higurashi sighed, having decided that she should tell them most of what she could tell them about that night. "He was very charming, but he wasn't ready for any children and I had always wanted them. So I didn't tell him even though I should have. I thought that he would be better off not having to focus on children back then and I just never got to contacting him after that." Mama Higurashi explained – looking slightly pained as she did so. She took a sip of water as she waited for her children to absorb the words.

Kagome was looking at her lap, her hands clenched into tight fists, nails digging into her palms. Sota's face was blank as he looked at her, which was slightly terrifying as he was usually a very expressive child.

"But now… Now I think would be a good time for you to meet him. I think you would benefit from getting out of the country for a while," Mama Higurashi said, her voice almost a whisper. "Everything has been arranged with Sesshomaru's help." Mama Higurashi finished, her voice holding a note of finality as Kagome finally looked up again, her daughters eyes were filled with a small amount of panic. Mama Higurashi understood that everything must have been frightening, something that was not helped with how fast things were progressing.

So she saw herself out of the room and let her children think.

(/#¤#\)-(/#¤#\)-(/#¤#\)-(/#¤#\)-(/#¤#\)-(/#¤#\)-(/#¤#\)

"I think you should meet him." Sota mumbled; looked at his sister who was motionless besides him.

"I know; it's just a little much I guess. I really wasn't expecting my father to be Ironman though." Kagome muttered, a note of hysteria leaking into her voice.

They sat in the living room for a while, neither of them saying anything, just gathering courage and strength from the others presence.

Kagome eventually sighed and got up to go take a long relaxing bath, hoping to hell that it would help her clear her mind and help her make a decision.

(/#¤#\)-(/#¤#\)-(/#¤#\)-(/#¤#\)-(/#¤#\)-(/#¤#\)-(/#¤#\)

Kagome's thoughts flew as she took a bath.

She understood why her mother had not told her sooner. She knew she had been a mouthy little shit as a child, she knew she would never have been able to keep such a secret – no matter how much it pained her to admit, but it was the truth that she had been a damn terror as a young child.

She sometimes wondered how her mother had put up with her.

She was old enough now to understand that Tony's enemies wouldn't have given a damn that she was a child, they would have taken advantage of her vulnerability and then they would have tried to pressure Tony into doing something for her release, something that he probably wouldn't have done as he knew nothing of her and would probably not have taken any message from kidnappers seriously.

It was something that would probably have meant an early death for her.

So she was glad that her mother had kept the secret, though she wondered at the weirdly blunt way she had revealed it as it was not usually the way her mother would do things (it was only later that she would realize that Sesshomaru had probably roped her mother into telling her about her father).

When she went to bed that night she let herself marvel over the identity of her father.

Her father was Tony fucking Stark, sometimes known as Ironman.

What a fucking day.

Kagome spent the next several days wandering around the shrine, trying to let the information sink in. It was both confusing and amazing to her as her father had always been a, sort of, abstract concept to her.

She would never have imagined that her father would have been such an important person; it was mindboggling to be honest.

So she wandered around the shrine and tried to get some semblance of order in her thoughts while she pretty much ignored everyone around her, not to be mean or anything, but because she simply couldn't deal with them at the time.

(/#¤#\)-(/#¤#\)-(/#¤#\)-(/#¤#\)-(/#¤#\)-(/#¤#\)-(/#¤#\)

"Kagome, are you alright?" Shippo asked, breaking her from her seemingly never-ending brooding – because, let us be honest, that was what it had become at that point.

"No, but I will be." Kagome said, attempting a smile though she was not sure that it became anything more than a grimace – from the look on Shippo's face, she knew she had utterly failed at smiling properly as he sent her a very unamused stare.

"Don't worry Shippo, it'll be alright." Kagome said, managing a miniscule smile this time which was enough to let Shippo know that she was not just telling him that it would be alright to pacify him, that she actually meant it.

So Shippo let the matter rest though continued to talk to her to keep her thoughts from spiraling any more that day.

He succeeded beautifully.

"This Sesshomaru has arranged a plane, a hotel room and an appointment at the New York Stark industries building." Sesshomaru told her, his tone making it clear that she could not argue and that she should just accept his command with a smile and a 'Thank you very much Sesshomaru-sama'.

Which he knew very well he would not get from her.

"You have what?" Kagome asked incredulously, staring at him with wide eyes. She felt completely blindsided.

"Your plane leaves in four days, a car will take you to the hotel; the appointment has been booked for two days after you arrive in New York which shall give you enough time to rest. I have made a cellphone ready for use if it should be necessary for you to get away if things do not go as desired. I expect you to allow them to do a paternity test so they will be sure that you are not lying and I expect that you will be surprised at the reaction Mr. Stark will have once he realizes you are his daughter." Sesshomaru stated; voice flat though still somehow sounding like he was expecting her to not argue and to just do as he had demanded.

And no matter how much Kagome hated it, she knew that she would not win this battle against Sesshomaru, so she sighed and just agreed with a pout.

Damn yokai was like a dog with a bone sometimes.

'Hah. I made a funny.' Kagome thought, snorting a little at herself whilst ignoring the imperious eyebrow Sesshomaru lifted at her for snorting in his presence.

Mama Higurashi had occupied herself in the kitchen for a while, worrying about everything.

She was unsure if this was the right thing to do for her daughter, she had pretty much dumped everything on the girl all of a sudden and expected her to be happy and not have even a single protest to just being shipped off to see her father.

She worried about what Tony would do. Would he throw her daughter out of the building without hearing what she had to say? Would he find out and then decide to keep her daughter away from her? Would he just throw money at her and make her never come see him again?

So many possibilities and she had no way of knowing if any of them would happen.

She did not know if he would be unhappy with a daughter or if he would be happy to have a daughter.

One thing she was fairly sure of, however, was that he would be angry at her for never telling him that he had a daughter.

He had, whilst he was very drunk, spilled that his dad had been a shitty father and that he would love to be a better dad to any of his offspring so he always hoped a little that he would have a child at some point that he could raise, spoil and teach. She knew he would have loved to know about Kagome earlier in his life.

She had just not believed that he had been ready for it and had, thusly, withheld Kagome from him.

She felt like such a bad person for having done it, but deep inside, she knew that there was nothing she could do to fix what she had done, she just had to live with the outcome.

No matter how much she might come to hate that outcome.

Four days later saw Kagome being towed by her mother to the airport.

Mama Higurashi had been a whirlwind the last couple of days while she packed Kagome's bags. Checking that her little girl had everything she would need, probably even a few things she would not need.

Sota was gawking at the plane while Kagome was being pushed onboard. Her family had a few minutes where they could be on board before the plane would begin taking off and Sota was making the best of it – in other words, he was looking at absolutely everything he could get into.

Kagome could not help but feel slightly amused at her little brothers antics, he had always loved technology, not that Kagome did not like technology, she just liked making it more than she liked looking at things other people had made, no matter how impressive those things were sometimes.

Then it was time for hugs and a few words of encouragement from her mother and brother – along with a warning from her grandfather that went something along the line of: "Beware of the yokai…" and then derailed from there, which meant that Kagome had paid his words absolutely no attention, which he knew if his little knowing smile meant anything at all.

Not to mention the complaining he usually did when she lost her concentration.

But, in the end, the only thing she could really do was to sit her butt down and fasten her seatbelt whilst hoping that her trip would not be for nothing.

Kagome took a deep breath and then the plane was off.

(/#¤#\)-(/#¤#\)-(/#¤#\)-(/#¤#\)-(/#¤#\)-(/#¤#\)-(/#¤#\)

She was so thankful that Sesshomaru had thought of how much trouble she would have getting around the airport as she was sure she would have been beyond lost without his assigned guards/guides.

It had not taken them long to get her to the awaiting car with her luggage somehow already having made it there.

Kagome grumbled a little bit but could not help the swell of affection she had for Sesshomaru.

She grew slightly irritated when she saw the way too expensive hotel Sesshomaru had booked a room for her in, she wanted to scold him, it did not matter to her that she already knew that it would have been something that he would never ever budge on, no matter how much she complained.

So she sighed exasperatedly, took pictures for Sota and then let herself soak in the overly grand bathtub – which she almost fell asleep in.

Then she went to bed and slept until it was around lunch time the next day, which surprised her as she did not usually sleep that much.

The rest of that day were spent relaxing and reading up on what she could find online on her father whilst she studiously ignored the file Sesshomaru had sneaked into her bag, she was fairly sure that the file would contain a lot of information about her dad and the people he surrounded himself with.

She did not want to come in with the wrong impression, so she ignored it for as long as she could.

So, the next day, she pulled out the file when she got out of bed, immediately scolding herself and placing it on the table. Her eyes kept straying to it during the day and, eventually, she caved and opened it.

Right on the page with the arc reactor, which she was fairly quick to page away from.

She was not comfortable with knowing things he might possibly not want her to know.

So she found the page with some of the generic information on her father.

His name, his known family, associates, friends, accomplishments and so on.

It was only when she went to bed that night that it dawned on her that she would, possibly, be meeting Tony Stark the next day – she still was not sure of who her meeting would be with, as no one had told her.

Though her most prominent hope was that he spoke Japanese as she knew her English was utterly horrible and she tended not to want to expose anyone to that if she could avoid it.

She fell asleep clutching an extra pillow and praying for everything to go alright the next day.

There were a few things I thought I should clear up for everyone in regards to this story;

There will be some type of 'bad guy' at some point (there is, of course, the typical Hydra goons, Loki and Killian) though they probably won't be playing an overly big part in this story.

No romance, though I might write in a one-sided crush type thing (more specifically Loki being completely infatuated with her for some reason I have yet to finalize in my mind). Tony would probably find it hilarious yet infuriating or something along those lines – he definitely won't like it!

Enough of that! Thanks for all the comments, favorites, alerts and C2s (This story is on 4, which is incredible) – It means a lot to me.
