serious question. I'd want to reveal the sailor moon secret to our parents at some point, as it would give us much more freedom to act (and because I always disliked the "useless adults/keep them in the dark" trope).
When do you think it would be a good moment?
I think we'd want to at least wait until we meet Rei, as we'd then have some support we could point at and say "Look, people will die if I don't do this. And by People, I mean everyone. Us included. And I have friends that are helping me".
Full Inner Senshi team could also be a good moment, though it's a bit too late for my tastes.
...Damn, it will be a very interesting conversation if/when it happens.
The secret identity dilemma is a tricky subject, especially for school aged defenders of hope, goodness and celestial bodies. The number of times a plucky protagonist has been imperilled due to being forced to choose between maintaining their masquerade or risking it to save lives is far too often. The more people Usagi has to work around, the more divided her double life becomes, the harder it'll be to keep sailor moon secret.
The motivation for telling her parents is thus obvious, not having to work around them and potentially having their support as 'trusted adults' who can help arrange things like emergency absences via sick notes or such if Usagi has to skip school to save lives and fight evil.
There are downsides though, depending on how Usagi's parents react. While thankfully unlike some protagonists we can prove the existence magic/powers quite easily, proving the 'only I and 9+ other people can save the world' part is significantly harder, and might raise some questions like 'why shouldn't we call the government?' or even lead to Dadsagi/Momsagi doing it behind our back. They'd only have Usagi's word + Luna and however many Sailor Senshi we manage to scrounge up before hand, and that's assuming they all agree that we should tell them.
Luna has previously protested letting people who can't defend themselves against magic in on the secret due to how they might get involved/targeted and she does have a point. If telling our parents motivates them to get involved they might end up throwing themselves into the line of fire in a misguided attempt to protect their daughter, or lead to them leaving/following clues on magic straight into a Youma trap. The other Senshi might have similar reservation or one's that I haven't thought about yet.
On the other hand, the masquerade is certainly a temporary affair. This isn't Harry Potter, where the status queue dived between a 'magical' and 'mundane' world is narratively sacrosanct. If we don't break the 'masquerade' first the dark kingdom eventually will as their life drain operations begin to ramp up. So we need to recognise that the 'end goal' involves having basically the entire world in the know and firmly set against the dark kingdom...
So back to Usagi's parents, when should they find out, and how?
Well, it needs to be after we convince Luna and any of the other Senshi on board that its a good idea/the right thing to do. It should preferably be after Usagi's had some time to come into her powers, and grow a bit more as both a protector and a person. Perhaps once Dadsagi/momsagi notice how much Usagi is changing/growing in such a (relatively) short amount of time, we can unvaile the whole, 'magical past life and fighting the forces of evil' as an explanation for Usagi's sudden maturation of character (Assuming this happens after Usagi's Overly emotional trait has been weakened or even nullified completely)
It should also be, again preferably, before the entire world is read in on the whole, dark kingdom vs moon kingdom situation, at which point revealing it to our parents would be... awkward, to say the least. This leaves a large band of time for the identity reveal to be placed in, thought it is worth noting that the longer we wait the higher chance something unexpected will happen which could upset any reveal plan we make, so we should probably tend towards earlier rather than later on this scale.
As for how to reveal... get Luna to assist as we proceed to prove that magic is real, then provide some proof that A) The enemy we fight is very real B) That we are specially equipped to deal with them in a way most people aren't, and C) That getting more people involved willy-nilly will cause much more damage than good.
Those are just some ideas though, and honestly considering Usagi's current relationship with her parents (which sadly seems to reek of 'disappointment child', though that might just be me reading too deep into it), I don't think this reveal is going to be happening any time soon.
Anyone else have any ideas/thoughts on this?
