About the fact that she’s stuck in her age, there’s also the possibility that she lacked the resolution to grow. She have magic inside her; it is possible that she unconsciously willed herself to stop growing because she doesn’t feel confident about herself as the next ruler of the galaxy (imagine the pressure!!!!!!!!). She sees her mom as this majestic queen whome she can never succeed, which is reflected in the scene between Chibi-usa and her dad.
It all signifies the importance of Chibi-usa’s observation of her teenage mom as the first step towards her resolve, where she finally gains the ability and power (power of confidence, that is!) to break the binds that also kept her from using the Legendary Silver Crystal.

My understanding on the 900 year Chibiusa has always been, since I read the manga like 10 years ago haha, that since she is half Moon decedent and half Earth decedent, they don’t understand exactly how long it will take her to grow or develop because she is the first of her kind. It seemed to make the most sense considering her family is confused as well.

The boys at her school look significantly bigger than her, there is a chance that she didn’t start school 800 years ago because she hasn’t been growing at a normal pace. Now that she is in school, everyone is bigger than her possibly because she still isn’t growing even though she has actually moved up the grades in school.

As for the uniform, Japan LOVES the sailor suit and I don’t think, no matter how much time shifts or how many years pass or even if fashion reverts to medieval clothing, they will ever drop the sailor suit girls school uniforms. Just my opinion after living there and talking to students and teacher on how much they love them lol. Also uniforms are really strict so it’s no surprise to me that even a princess would have to wear one. Maybe she doesn’t like to dress like a princess outside of school since she feels so insecure and like she isn’t a princess at all. It’s also super common for girls to stay in uniform even way after school ends because changing into new clothes is wasteful (more laundry to do) and time consuming.

So there’s my spew

We could also guess that Chibiusa has some kind of an unknown and undiagnosed disease that prevents her from growing. Maybe this disease could also prevent her from developing the magical skill she was expected to develop ? Or maybe this undiagnosed disease makes her so depressed that she unconsciously blocks the development of her magical skills ?

Like some of us, the fact that she is an adult princess trapped in a child body and wearing a school uniform annoys me a lot… It’s completely absurd and ridiculous.

About the Black Moon clan (before they were found by Phantom) : I think their causes were noble : indeed, to make humans beings almost live as long as the original Moon people may be seen like a transgression of the natural order of cosmos and fate.
See what the Ancient Greeks called “hubris”, which is a very important word and notion in Ancient Greece (and in AG, even the gods cannot master the “fate” itself… It is the supreme completion of cosmos, and it’s a completion well beyond the gods’ powers…). Hubris is considered to be the highest form of crime ; it’s founding principle is pride, arrogance, lust and violence… On the paper, living for a thousand of years seems beautiful, but isn’t it unnatural for the Earthlings, that were originally granted by the cosmos the possibility to live for about a hundred of years ? Isn’t it a spoiled kid and immature desire to live for more with the help of magic ? Imagine a lady from the Moon descend on Earth and gives you and the whole planet the possibility to live for a thousand of years… would you accept or would you militate against it ?

Maybe the 4 guys of the BM clan were good and serious souls that were forced to become brutal activists in order to be heard by the royal family and it’s people… But then, they were found by Phantom (an avatar of Chaos) who manipulated them, and they became the very villains we know, eventually falling themselves into the highest form of hubris !

My theory may be easily broken when we know that Sailor Moon/NQS is an avatar of Cosmos… But I wish it can explain a little the original motivations of the BM clan.

The quality of the animation was very very good. I think this is the first time we have such an animation in the story of SMC !

And if I were Sailor Moon, I would considered myself to be lucky… Demande is far way hotter than Endymion ! Can’t wait to see Saphir too *_* .

Could be money or they could just be getting used to the tools and the process. Still there are episodes that are worse than others. Maybe there are just different teams working from one episode to another.

It makes since that Pluto didn’t try and kill Chibi-usa but that she did try and kill Sailor Moon though. Chibi-usa came through the spacetime door which only members of the sliver kingdom could so Pluto know exactly who it was when she came through. Sailor Moon, on the other hand, came from outside of space and not through the space time door. Therefore, Sailor Moon was a threat from outside of spacetime trying to break the taboo of time travel and had to be killed. It could have been anything or anyone…even something designed as Sailor Moon….so that part of the story makes sense.

The whole 900 year old thing though seems weird still though. Unless they really just expand lives out. So like if you live to be 1000….maybe that’s the equlivient of 100 years in our time? So like each century is actually like a decade for our timeline? Doesn’t solve anything to do with Chibi-usa though lol and exactly…they would make her stay in the same grade for 900 years? LIke that’s a major plot hole in Sailor Moon that never made sense.

I don’t get why she always wears a school uniform either. If she is the Princess, wouldn’t she wear a princess gown? And it looks like the people of Crystal Tokyo wear some sort of ancient mid evil type clothes….such as the boys that were teasing her wearing old looking robes, yet there Chibi-usa is wearing a modern day school uniform. Wish they would have cleaned up the timeline and plot holes from the manga in Crystal better….
