The Fortune Cup has officially begun and the first duel pits Krieger against Leo, who is disguised as his sister Luna, as she did not wish to participate. Krieger's aircraft machine monsters are giving Leo's Morphtronic monsters a hard time. Meanwhile, Zigzix, Goodwin's scientist, puts his latest invention to the test: a device that detects signer activities. But Leo is unaffected while Luna is. Leo loses his duel and Zigzix finds out that Luna was in the stands during the duel.
