Ryuujou, the aircraft carrier from Kantai Collection

Battleship Princess is an enemy found in Kantai Collection. She was the boss of the fifth event map during the Fall 2013 event and reappeared as an enemy in the fifth event map during the Spring 2014 event, the sixth map in the Summer 2014, and the third and fourth maps in the Fall 2014 event. Fondly known as "Dyson" by the fanbase. Because, like the vacuum cleaner brand, she "never loses suction", which in this case means facing her is a never-ending drain of one's time, resources and sanity as well as sucking up shots intended to hit the boss.
