Working as a Secretary Ship, Kaga notices that the Admiral was redirecting the naval base resource into funding his sexual escapades with various shipgirs. In the ensuing argument, the Admiral jokingly remarks that she should just relieve his sexual tensions in place of other girls.
Kaga doesn’t take it as a joke.
The poor admiral has yet to realize that he has just stepped on a land mine and delivered himself straight into the hands of an insatiable sex fiend hiding under Kaga’s cool demeanor.
