"Cagalli Mark Three" is a Gundam Seed h-doujin featuring Cagalli. There's enough story here to make me wish I knew a decent amount of Japanese, but it isn't too incomprehensible.

Cagalli doesn't quite match her anime appearance (notably, her hair is depicted as being much darker). The other characters to appear are more easily recognizable, strangely. Otherwise the artwork is very close to the original's.

The doujin has a bit less liquid squirting all over than most doujin seem to, but there's still quite a bit of it. Otherwise, the sex scenes are fairly typical h-doujin stuff, but are decently done. (Personally, I'd have enjoyed it more if it wasn't basically a rape sequence.)

Overall, it's an alright doujin. I'd say it's good for Cagalli fans who don't mind a few liberties being taken with the story or art.

==Spoilers==
The story here seems to be that Cagalli and her sidekick Ledonir (the dark-skinned man) are pilotiing some mobile suits in a space battle, only to be defeated and captured. After being brought to Muruta Azrael, the crazy leader of Blue Cosmos decides to have his rape gang (!) force themselves on Cagalli. This scene extends for most of the doujin.

There's lots of screwing Cagalli in various ways by several men at the same time before Azrael himself decides to join in.
