As a reminder, ARK isn't a lolicon, but a destroyer-con. It just so happens that most destroyers are lolis. Ark still likes the girls like Benson, Grenville, and Cygnet who are definitely on the more busty side as well. Ark is trustworthy enough to be in charge of security at dances, so. . . yay? Honestly, fan works play up her Destroyer-con tendencies up like Littorio's lesbian tendencies (Littorio appreciates beauty but most of her lines are more self-confident and ego-centric). Just like Akagi isn't actually a yandere, just portrayed as one because that is what her initial lines suggest (and not her actual secretary story).
