Was quite out of the blue when 86 revealed humans were never allowed past their coastlines, so definitely Azur Lane's setting as unsafe as their seas are is still safer than 86's seas.
Kind of fitting that the only time Aru actually manages to be considered a 'threat' or a true 'villain' is when it's not even her fault and completely accidental.
At this rate, I wouldn't be surprised if Black Suit is the next one shown getting ready to eliminate the 'threat'.
