Actually, chiketsu doesn't mean "ugly warrior"--that's just what the Chiketsu counterpart in the Shui Hu Zhuan book must have been called or known as.jeane star is chiketsu star of noble wisdom.
the mean of this star is the ugly warrior
Chiketsu = (if you're able to see the kanji:) 地傑
地 (chi) = Earth
傑 (ketsu) = excellence
So yeah, sorry I don't really contribute anything really to the mystery that is Jeanne, but thought I might point that little bit out at least about what her "star meaning" really means
I've noticed that some of the star titles such as Nanami's "Star of Logevity" (天寿) match the second kanji character.
天 = Ten (heaven/sky)
寿 = Long life
But someone such as Luc who is the "star of idleness" (天間) the second charcter in Tenkan is for "space" or "interval"
--then again, perhaps in Chinese that character is actually used to mean "idleness" since even though Japan uses the characters like China, sometimes the meanings are different for the same character. After all, these titles came from the book first right?
