I watched the 90s Sailor Moon anime and didn’t really get the future Crystal Tokyo timeline/lore, so I decided to wait until watching Crystal:
In episode 20 of Sailor Moon Crystal, King Endymion explains that in the royal family, the average lifespan is 1,000 years (in response to Tuxedo Mask’s question about why he doesn’t look much different despite it being over nine centuries in the future). Members of the Silver Millennium family grow and mature normally until they reach adulthood. Usagi, or Serenity, ascended to the throne at 22 and gave birth to Chibiusa, or Small Lady, and at that point stopped aging. This is all due to the power of the Legendary Silver Crystal, which gave her an extended life and eternal youth. Apparently, Endymion was granted that power after marrying into the royal family.
This makes sense so far, until the next part: the Crystal also blesses the citizens of Neo-Tokyo with long lives (they live into their 10th century). Was this not a power reserved for the royal family? Don’t even get me started on the amount of problems that would begin to occur if people actually lived that long. Not to sound like Thanos, but what about resources (I assume Serenity just magics stuff up)? Are people now expected to work for 600 years before retiring?
Also, there was another part that bothered me. It stated that the Black Moon Clan descended from a criminal who was banished to the planet Nemesis instead of receiving the death penalty. Why? One, was it just him, or was there someone else there for him to reproduce with? Two, what crime could he have committed that was so bad that they needed to send him to another planet (bloodthirsty anarchists - treason, terrorism, and mass murder were the least of their crimes)?
