Lover of the era Diana A!

Synopsis

The completion of Diana A — the new robot meant to replace Aphrodite A — is just around the corner. Sayaka, who had been down lately, gets her spirit back and trains tirelessly on the Scarlet Mobile, the super bike that will serve as Diana A's cockpit. But the Scarlet Mobile is snatched by Geronimo, the leader of a biker gang. Koji goes to take it back, only to lose his memory after Geronimo beats him. Seizing this unexpected chance, Dr. Hell sends the Mechanical Beast Drago U into action.
