GHKR-75 Shinraku Aine, Ohtobe Naoko: Super Heroine Dimension 41 – Battle-Type Female Astronaut Gradknights GIGA (GIGA)

Astronaut Gradknights, equipped with special space combat suits called Gradectors, were created to fight against Gradnoids—alien lifeforms that despise humanity. Maria Kashishi, one of these elite warriors, is captured and brutally assaulted by three Gradnoids while searching for her missing brother. Discovering that one of the Gradnoids is actually her transformed brother, Maria fights back with both body and soul wounded. But before her stands Gradnoi Queen, said to be the origin of all Gradnoids. With her spaceship destroyed and unable to wear her Gradector suit, Maria challenges the Queen in hand-to-hand combat, only to be overpowered and torn apart by overwhelming strength.
