They have angst attached to their lives indeed.
Why is there almost always some kind of tragic undercurrent with this pairing? Don't see much with other parings if at all.
Well, Midway, I guess. In the real WWII battle the carriers Akagi and Kaga were fatally damaged and ended being sunk by their own destroyers escorts. And that was the beginning of the end for the IJN.
Wich is a plot point in the Kancolle anime. (Oh, boy, that week waiting to see what would happen was pure torture!!!)
By the way, I liked the Kancolle anime. Sometimes silly, sometimes serious, but worth the watch.
Ooi, in VERY posessive lesbian mode is awesome. (And BADASS).
Mutsu and Nagato are pure LOVE.
I would have loved to see more Akaga, maybe in the second season.
