Heihachi Edajima, an Otokojuku veteran and survivor of the Man Bomb, starts up a new facility known as Onnajuku, a tough combat training facility, and begins training several Japanese women to fight for their country. The manga follows Momoko Tsurugi, a descendant of former protagonist Momotarou Tsurugi, who recently enrolls in Onnajuku.
