Ooyodo got tasked with taking care of shipbeasts, shipgirls who lost their human body for some reason
Translate the rest if able, oh great translator
There are actually two naval bases involved in this series, Kure and Hashirajima. Kure is the one with Ooyodo and Bismarck while shipgirls from Hashirajima appear from time to time. Some shipgirls that both Kure and Hashirajima have obtained might have different beast forms as well. Unless stated so, most of the shipgirls are implied to be from Kure.
