The three girls feared in an endless war... A story of the price paid for being the strongest.
October 1944 in a certain timeline... The Battle of Leyte Gulf (Battle off Samar) has begun. The Navy's main force, including the Yamato, Nagato, Kongo, Haruna, Kumano, and Suzuya, has deployed. The Army is engaged in the Battle of Leyte, and the Air Force is conducting the first sorties of the Kamikaze Special Attack Units. Amidst this, three girls exist within the branches of the military. A girl in the Navy is said to be a lucky charm; as long as she is aboard, the ship will not sink. However, in exchange, the ship always returns heavily damaged. Having withstood the shockwaves of the Yamato's main guns, she is feared by everyone. A girl in the Naval Air Service was sent on a Kamikaze mission but miraculously returned unscathed. Because of this, she is bullied by other pilots and berated by instructors who ask, "Why are you the only one who survived?" She is hated more than she is feared. A girl in the Army single-handedly defeated 20,000 enemy soldiers. Because of this, she is avoided and feared as a terrifying, immortal monster, despite being the strongest.
