Japan builds its first aircraft carrier, the Ibuki, to deal with escalating world tensions.

What were to ostensibly be fishing boats fire upon nationals and occupy southern islands of Japan suddenly. Enlisted members of the Japanese coast guard are detained and all Japan can do is send an aircraft carrier and a supporting armada to the area. The captain of the aircraft carrier, his second-in-command, the crew and other ships' crewmen are in a new and unexpected domain. The story takes place over twenty-four hours.—aghaemi
