A close collaboration between the professor and Hayato's father leads to the creation of a new research installation not far from the laboratory. The demons do not miss an opportunity to attack the new base with a robot demon and Asuka, Hayato's sister visiting the family, is seriously injured in the bombing. The Getta team rushes to the bedside of the girl who urgently needs a blood transfusion. Ryo, the only one able to donate to the girl, volunteers while Hayato, in order not to feel useless, faces the monster aboard his Getta shuttle. Benkei and a very weak Ryo reach their partner and together they form the Getta Robot to face the enemy. The superiority of the latter, however, is devastating and Rygar ends up KO. But when all seems lost, a beam coming from his father's laboratory destroys the monster but the installation, due to an overload of energy, explodes into a thousand pieces. The father saves the life of his son with whom he will clarify his feelings, marred by years of misunderstanding. Finally, the sister, after a well-deserved convalescence, fully recovered.
