She was a big believer in preserving the union. Her breasts weren't that big and she wore a relatively loose fitting uniform.
The story wasn't really a traditional one, since it was a "Weird Wars" tale in a comic book.
Might as well give you the ending.
Basically some other POWs that are just thugs end up killing her and the protagonist's other friends for their supplies. He spends the rest of his time at the camp ignoring his declining health building a weird "golem" type body of wood, metal and his girlfriend's skull.
It ends with her coming back as this creature that the guy brings to life with his old pocket watch and his own dying beliefs of them holding magic. She kills all the thugs in the middle of the night and goes back to die with the protagonist.
