The South Dakota-class... You've met three of the four total sisters by far - South Dakota herself, Massachusetts, and Alabama at this point. Very well-performing shipgirls, pretty much a given from both their performances back in the Second Great War, and the 406mm ship-sinkers they use...
Oddly enough, you haven't seen the second sister, Indiana yet... Well, until today. She's transferring Naval Bases, heading to yours, now.
A few days or so of waiting, and at your Office Door, she knocks at it twice, before entering, her hands in her jacket's pockets. Made obvious to you, is the wide and friendly smile on her face, how laid-back she looks, and the scar on her left cheek... Probably from that collision she had with USS Washington back in the Great War...
"Yo, Commander! Nice to meetcha!"
She crosses her arms underneath her chest, acknowledging you, almost like you've been friends for a while, despite her just meeting you.
"The name's Indiana, second ship of the South Dakota-class of Battleships! Let's ride this Victory Train together, and kick some ass."
