Chibichibi, the smallest girl (w/ dark pink hair), is close to 1k years old.
Setsuna, next in line (black hair), is over 1k years old.
Haruka, next and blond (looks white), is about 19. Trust me, most have "regular" ages...
Michiru, next w/ teal hair, is about 19.
Minako, next and blond, is 17.
(Lower row first) Makoto, next and brunette, is 17.
Hotaru, next with black hair, is...well...odd. She's both twelve and newborn. (don't ask)
Next is the raven haired one, Rei is 17.
(middle row)Another odd ball, Chibi-Usa with the pink hair is well over 930 years old.
Next to her is Ami who is 17.
At the top is Usagi. She's 17.
^Also, there are funny facts with all of them that would just confuse you if I went into it.
Oh, and Usagi is Chibi-Usa's mother, but Chibi-Usa was born when Usagi was 23. So...we get interesting things at times... And Chibi-Chibi is the sould of a person from another plantet... Yeah...confused yet?
