***** and blue - I am absolutely certain of this answer, if you think I'm wrong then you must be wrong.
**** and green - I am almost certain of this answer
*** and dark yellow - I'm pretty sure this is right. If it is italicized then it is classified as a THEORY.
** and orange - I'm not certain, but I think this is correct. You should ask Takeuchi Naoko herself, only she would be certain.
* and red - I really don't know,I'm going to take a shot at it but you should ask someone else who may know more than I. (or Naoko)
no star and purple - a wild guess, I have absolutely no idea. This is definitly not correct.
*****Answer: The Inners never had any really serious realtionships in the series because their true soul mates had been killed by either Beryl or themselves. Allow me to explain, Jedeite, Nephlyte/Nephrite, Zoisite and Malachite/Kunzite were origionally generals in Prince Endyminion's Army during the Silver Millenium in the manga. (Zoisite was a man in the origional Japanese version and is still male in the translated manga) The anime series didn't include this. The set up goes Jedeite and Rei, Nephylte and Makoto, Zoisite and Ami, and Kunzite and Minako. The love between the inners was apparently much like the love between Serenity and Endyminion, and since the generals are now dead, though they reappear in the SuperS manga basically whining that they can't do anything, the four girls will probably never have another serious realtionship during their lives. (And to spoil any fanfic which doesn't reencarnate the generals -> it doesn't stay within the guidelines of the Sailor Moon Universe.)
**Answer: I think it has something to do with how the manga was written. In the manga the senshi guarded the planets (ie. Mercury, Venus, Mars, Jupiter, Saturn, Uranus, Neptune, and Pluto). Earth did not have a senshi, most likely because the moon watched over the earth. So there was a Sailor Moon instead of a Sailor Earth. There were no senshi on earth and since Endyminion was a guy and not a Sailor Senshi he did not get a planetary symbol on his forehead. Otherwise, I think it's just a female thing. ^_^()
