Manga: Claymore

[Assassin]

The "true form" was actually the one claire cut up, the naked woman. The one that resembled Riful was her fake 'true form'.

As for her technique, she uses both. Originally she learned flash sword (pre time skip)...after the war in the north (during the 7 year time skip) she also learned Wind Cutter. This was because wind cutter doesn't require yoki, whereas flash sword requires the user to fully awaken their arm. And during thier absence they were all trying to avoid using any yoki to avoid detection.

When she said her accuracy had increased but the power had decreased, i believe she was talking about her flash sword....as that was the technique galatea witnessed when they faced Riful/Duff. At that time, claire could do it but not control where the slashes went. Now she has better accuracy, but because she's avoiding using excessive amounts of yoki (thats my theory atleast), its power has decreased.

And lastly, no claire and priscilla haven't fought in the manga yet.

[Shinji Ikari]

I don't think she meant the flash sword specifically since she can't use it again until the gang decides that it's okey for them to use yoki. Which they haven't.

So I think that the reason the power has gone down is because the windcutter is weaker than the flash sword. But since she has been able to practice that for so long her accuracy has gone up (in general).

I think there is a fairly good chance of Galatea joining the ghosts, just give her a pill to make her yoki disappear :P However, I don't see this happening because Galatea is a loner, she has exposed her yoki (it seems lame to use a pill and join the gang) and her powers are already complemented with the other members. The only reason I see for her joining would be a bigger party and her powers to tweak yoki flow (which doesn't really work all that well against stronger AB's) being a very small reason...

In claymore, authors have been strong enough to give us so few details so that they can come up with lots of surprises.
I wouldn't be too surprised to see Galatea progress by a huge leap just by getting closer to the 7.
Why?
Because she is very talented and maybe only needs to know that her limits are a lot higher than she thought. She may realize that the 7 did go much further than what she thought was possible. Thus may be able to get there (or even only half the way) very quickly.
And thanks for pointing out her ability to tweak yoki, as it is certainly a very handful skill she has that could prove very useful if brought to the level of control Claire or Miria have for their powers.
