Thor: Son of Asgard (2004) #3

Sif

Sif was born a second generation goddess of Asgard and eventually became Thor's lover.

Thor

As the Norse God of thunder and lightning, Thor wields one of the greatest weapons ever made, the enchanted hammer Mjolnir. While others have described Thor as an over-muscled, oafish imbecile, he's quite smart and compassionate. He's self-assured, and he would never, ever stop fighting for a worthwhile cause.
