-[] Wait until the weekend, like we promised Maya. Make sure we aren't in Multiform at the time.
-[] Tell Dad we have something important to discuss
-[] Throughout all of this, show Dad carefully selected memories via telepathy, reinforcing/confirming our points.
-[] Tell Dad that 6 months ago, our friend came to us and told us that she'd had "superpowers" for years, and that she knew we had them too - and proceeded to prove it by getting into a spar with us.
--[] She knew we were like her from seeing us in a Garenhulder martial arts class - no-one who wasn't aware of the possibility noticed anything odd.
-[] We discovered she was a ki user because she figured out we were one too. By that point in time she thought they were super power and she had and still has no idea about the extent of ki use or the existence of saiyans. The masquerade is intact, she hasn't told anybody, and she didn't have any idea why she could do what she does. Revealing herself to anybody was a huge breakthrough for her, and she wasn't ready to share with anyone else.
-[] Since she had already come to us, we had two options to explain and stop her from getting more suspicious: We could pretend she was right and our powers were recent and we had no idea what they were or we could admit we were trained in them without mentioning anything relating saiyans.
-[] We decided to tell her that we were trained with them to stablish us as more informed than her and make her respect our opinions about it further so we could properly show her how to hide her abilities and keep a closer watch on how they developed. For this, we admitted that dad also could do it and had trained us. Since she already knew others could be like her and this didn't reveal the full extent of ki use across Garenhuld plus it gave her an incentive to come forward to dad herself about this if she wanted to further develop her skills, we considered this didn't hurt the masquerade that much over what her discovery did already and by admitting our family didn't want it known that we could do this, we could further guilt her into being more careful with her abilities since it was no longer just her secret to tell. She was already predisposed not to tell others but every bit helps.
-[] We miscalculated in that regard since she didn't want to tell others. She already had a bad experience with people not believing her when she was younger and such she didn't want to tell an adult. On one hand, this was convenient to us since it made it even more unlikely for her to show off her skills on top of her timid personality but she wanted us to keep this secret. Once this happened, we had three options: We could promise not to tell and come to dad anyways, we could force the issue or we could keep the spirit of the promise while coaxing her into coming to him herself. While the fact that she is our friend did play a part in our decision, we had to consider what was best for saiyan society and our house. In the end, her power level and potential made us reach the conclusion that the approach we ended up taking was the one that would be most beneficial to all parties in the long run.
-[] He knows how dangerous an untrained ki user training herself is, and then there's the issue of the masquerade or any other Saiyans detecting her, so we've been building her trust by teaching her self-control for a few months, and it finally paid off when she agreed to meet him about this. Teaching her to hide herself better in order to protect her was a big part of why we chose to do so but not the only reason. We wanted her to be happy with what would happen with her and, to be honest, we also wanted to share something with her but those were not the only reasons we did so, since we think the way we approached this would be better in the long run to integrate her and protect our society.
-[] When she came to us, she had a power level over nine hundreds with no real training behind it, which showed she had a talent beyond any recorded human save Uub. This meant that we knew she would be powerful if she received proper training and we knew she would come to the attention of saiyans eventually as she grew older and into her power. Once we knew about her, normal procedure is to tail her, make sure that she didn't tell anyone and arrange for her to fall in love and marry a saiyan. Maya's unique situation makes it so that this course of action is not the best one to take. For one, unlike normal cases, she can use ki which makes it so it would be harder to keep things quiet if there was some breach as there would be more evidence. For two, she would have access to our training methods when she was introduced to our society and she has the potential to end up as a power in Frieza's scale. While we are confident that she would not train to that extend if we asked properly, the potential is there. If she married into our community as a way to introduce her to it, her first loyalty would be to the house she marries into since they would be her family and her husband the man she loves. We trust her but it is our duty to plan for every eventuality and thus we want to tie that kind of potential as close to house Goku as possible. Since we don't know if the one who would catch her interest would be from it, that meant tying her to us which also has the benefit of placing her under our wing; we don't want people to use or see her because of her political value and while that is somewhat inevitable due to her relationship with us we want to shield her from that as much as we can. Our friendship is a good way to go about it and by the time she could marry we could easily be best friends, especially since we share a secret. However, she would then find out that we kept something this big a secret from her for years which would put a strain on it and it doesn't hurt to strengthen it more now. If we had come behind her back or forced the issue it would make that goal harder but we could hardly keep this from dad since it would be against our duty and people. This is when her high potential came up again and helped make our decision.
-[] The moment we mentioned we were trained, she was likely to ask for the same instruction. Not only did this let us keep a closer watch to her and bind her closer to us by having a mentor student relationship but we knew her power level would climb fast. One way or another, be it because we told that (with or without her permission) or because she would grow too strong not to sense, we knew he would find out about her before the end of the year. When we started training her, we told her dad would sense her eventually as she grew stronger so her choices would be to stop altogether or come clean to him. She is ten and we offered super powers so she wasn't going to choose the first so she would either be sensed or agreed to come to him before that happened; either way it meant that he would know about the situation before the year ended even if we did make that promise and only meant that there would be a few months' delay which wasn't that great in the long run. Furthermore, while we would get in trouble if she was sensed before she was ready and there is the potential we would get in trouble for deciding this on our own even if she wasn't and we came to him, going about it this way made it more likely for her to feel indebted to us for getting into trouble or risking it for her sake even though the promise didn't really endanger us that much.
-[] Besides, while we trust her and all we have seen point to it not being an issue, she needed a greater understanding of the danger of ki than the normal humans who discover a saiyan. This way, once she learns how to sense ki, there would be no need to tell her how outclassed she would be if she decided to do something unadvisable. She would be able to see it for herself and know it on a level other humans are simply not able to.
-[] That said, she wants to come forward. One of her biggest issues is about people not believing her and thinking her stupid or a liar about her powers, especially adults, to the point she is afraid of that even though she had proof and has gone out of her way to keep things secret. Dad has no reason not to believe her or being mean about it. She currently has no authority figures she trusts in regards to this other than us and we can see she would like a place in which she would not be considered weird about this. We have also told her that teaching her sensing, which would be the biggest threat to the masquerade, is something that Berra would have to decide whether we can do or not since it affects other people. With all of this in consideration, we think that the best way to ensure compliance while minimizing problems in the long run would be to make her trust him and develop an emotional attachment.
-[] Also, she is our friend and shy and sensitive and worried people will be mean to her. So try not to frighten her?
-[] So, in summary, masquerade intact, really strange maybe-human who trusts us enough to be cooperative and will probably embrace Saiyan society with open arms, and you need to be extra nice to her because she's insecure as all get-out. Also, either she's a one-in-tens-of-billions-level human, or something else under some sort of masque, so something really weird is up and you might want to have a sorcerer take a look at her as soon as it won't result in her freaking out
-[] Once we have explained the situation to him and get across that it would be really important to us if he were nice to her, ask him for his opinion about how we could have handled this better and ask him how he plans to handle the meeting/what we are going to do about this.
-[] Then, when that is clear, go look for Maya and bring her so that she can meet dad. Accompany her during their meeting as we promised.
