Titre original : The Crimson Fang
Leele finally awakens from her coma. Eiji's out looking for Toga. Faye takes Toga to the orphanage where they grew up. It was sponsored by Sandman. She tells him that she resents him for taking her position as the Gravion's pilot. Faye tries to recruit Toga into the Grand Troopers. Just as he's about to give into her, Eiji arrives.
At the Grand Troopers base, Mizuki finds Luna as the President arrives for a visit.
Back with Eiji, he and Toga fight over things. Meanwhile, a Zerivire ship has appeared over the city. It creates a gateway where a bunch of Zerivire ships come from.
At the Grand Troopers base, Mizuki and Luna run into the President. Mizuki takes care of the President's guards. The president recognizes Mizuki as one of his agents. they take off in a plane, and pick up Toga and Eiji on the way back to the base.
Meanwhile, the Grand Trooper is fighting the ships. It isn't making much headway in the matter. Even though Leele has not regained consciousness yet, Toga takes her on his ship. (Yes, I know earlier I said she woke up; it's a slip in continuity.)
In the battle, Thoria gets knocked out early. The Gravion robot is seized by a Zerivire, and drained of its energy. Then Sandman calls forth the flame planet. A lot of energy comes out and destroys a number of the Zerivire.
