Plot
The year is 2035 E.R. Giant living creatures called Fiarem have suddenly appeared on Earth.
Although mankind tries to oppose them by releasing a large number of Ectis, a type of battle android, they are undeniably inferior to face the Fiarem, which are over 50 m tall and overwhelmingly powerful.
In order to overcome this situation, the Japanese Diet makes the decision to use Cell Growth Factor CGF-3 technology, which enlarges living beings, for military motives and send humans into battle as giant weapons.
Six heroines are selected as appropriate subjects for enlargement, and enter the Anti-Fiarem Specialists Unit, Ragna Strikers. These young women, trusting their bonds with the secret government agency, head into battle with their powerful enemies.
