The background of the story is set in the middle and later stages of the Pacific War, when the Japanese navy was greatly defeated by the US navy in the naval battle of Midway Island; four aircraft carriers of the first Mobile Fleet were sunk; 56 Admiral Yamamoto, commander of the Joint Fleet, was killed; the Japanese garrison forces of the islands in the Pacific were successively lost, and the Japanese navy was in a serious disadvantageous situation. In the spring of the 19th year of Showa (1944 AD), the Shenwei of the special young soldiers boarded the deck of the super-crossbow battleship Yamato, which at that time was the hope and symbol of Japanese citizens and soldiers. Shenwei endured the harsh training of the ship, and then ushered in his first actual combat-the Battle of Leyte Bay. In this naval battle, the United Fleet actually fell apart. When the cruel battle was ahead, the Yamato and its crew lifted anchor and ushered in its last solemn and heroic battle with the determination to protect the country. Everyone knows that they will be greeted by a large fleet of murderous American carrier-based aircraft.
