Bilan: Ayanami Doesn't Want to Be Caught as a Hunk

There is no male protagonist, and the protagonists are four families. It can be called "Ayanami's Daily Life in Minato". At the end of World War II, when countries all over the world were recuperating, the combined fleet from the United States was attacked by an unknown force early and was almost destroyed. Not only the United States, but also the fleets of the Soviet Union and the United Kingdom were severely damaged and had to retreat to the offshore seas, relying on road-based fighter jets and artillery to barely fight against these monsters. After discussions at the United Nations, humans named this monster that exceeded their own technological level: Siren.
