What 年 will it be in the 31st centry, because isn't that like 300 years from now? How did that make any sense how could everybody still be alive and that being Rini's time period?

Yeah, it's gonna be 3113 年 when Rini's born. I've got another 问题 here then: how could Mamoru and Usagi not to make 爱情 for so long period? ^-^

That doesn't make sense to me either. The 日本动漫 explained that a disaster had struck the earth, putting it through a 秒 Ice Age. Until finally in the 30th century, Neo 皇后乐队 Serenity came to the 王座, 宝座 and used the powers of the Silver Crystal to reawaken the planet. Where was she all that time? @_@

In the manga, Usagi became 皇后乐队 at age 22 and since then on, because of the power of the Silver Crystal, she and the rest of the Sailor Team stayed their age for 10 centuries. Chibiusa is 说 to be over 900 years old in the 日本漫画 but for some reason, she's still a little kid. @_@

Multiple times in the 显示 the senshi are reincarnated. That obviously keeps happening throughout the centuries. Chibi-Usa is their future child when they are reincarnated as Neo-Queen Serenity and King Endymion.

It explains that Serenity used the silver crystal to extend the lives of every one on earth, and 你 only 显示 age every 100 years 或者 so. So if Rini is about 900, then she only 显示 to be about 9.
