Azur Lane is, basically, Ship Girl Tohou. World War II Warships from various navies are personified as cute girls, and they generally hang out at the bases of their respective factions and do cute things until the plot decides that they have to do combat in battles along the lines of shoot-em-up video games. It’s not quite at a danmaku level – but only because the game series is designed to be played on a cell phone, and you don’t have that level of control with a touchscreen.
