This was the only day where I saw three in the same day.
Before this, in the Twitter feed there were some large numbers, which looked like the author was doing LSC, and just after this, Ushio's trying to pretend that a paper cutout is Yamato, so I'm guessing the author just blew a month's worth of resources and only got Naka-chans.
She then glowers at Kirishima and Haruna, presumably because of the belief that having a battleship as your secretary ship makes you more likely to get battleships (apparently, Yamato was the goal,) when the author had wanted to keep Ushio as the secretary ship the whole time.
