sailor cosmos is a very obscure character, yet i choose to honor her here. she appears briefly in the manga, as a "future form of sailormoon". some people believe she is chibichibi, but then again, what is chibichibi?
in the manga, chibichibi is everything that is good, pure good, just as chaos is everything that is bad, or pure evil. chibichibi sort of gives sailormoon her power and sailormoon can defeat chaos. cosmos is supposedly a future (ulitmate) form of sailormoon, that came to the past to change the way the battle went and decided against it (?) but i'm not sure. i have not yet read all of the stars manga, as i do not get smileMAG. i'm on my way though, part by part, piece by piece.
don't worry, i will soon have much more information about sailorcosmos AND chibichibi.
