It's been noted (see comments on post #1711208) that Kancolle fan artists are fond of depicting Akatsuki in reference to her introduction line, and I for one think it'd be quite appropriate to index such images on Danbooru in some way.
This could be done as a pool named "Kantai Collection - Akatsuki the First-Class Lady (?)" or as a tag "first-class_lady". (I'm leaning toward pool myself - that gives a little more flexibility for indirect references, whereas with a tag I'd feel constrained to limit it to posts that explicitly referenced the introduction line.)
Either way, the description could be:
For when Akatsuki is trying (and often, adorably failing) to live up to her introduction line:
暁よ。一人前のレディーとして扱ってよね!
I'm Akatsuki! Treat me like the first-class lady that I am!
What do you think, sirs?
