Ryuujou is a character in Azur Lane, light aircraft carrier for Sakura Empire. She is serious in her work, even thinking her week has the Saturday replaced by a second Friday and the Sunday by another Monday. She is ready to face danger, and is totally at the service of the commander, who rewards her sometimes with delicacies. To calm herself down, she says she goes and watches "the fish swimming around peacefully in the aquarium".
