The sun is also setting in the background for Aki, which is the important part.
If there's any symbolism in Asa's cover, it could be the fact that it's night time while she is Asa, "morning", while Yoru is "night".

I'm seeing too much blame being passed onto Yoru for having her giant ass stuck beneath the rubble. When you think about it, that's really Asa's fault for having such an inconvenient physique for fighting.
