@MistaJ1987 It's a battle of vanity: which of them is the most beautiful and desirable out of all the Goddesses? They count the number of men they've seduces as tally marks, and as of Ishtar's final scene in the series, Freya was winning.
That's great to know and I already saw the end result in the anime, but i'd like to know where I can find that quarrel, is it in the main storyline or is it off on a side story?
