While Lan is away in Sharo, Chaud and Maylu work together to investigate the disappearance of NetNavis who participated in the N1 Grand Prix last year. They meet a robot named Allegro and also re-encounter Kid Grave, now being controlled by Bass. After causing so much trouble, Bass gets rid of Allegro by destroying his CPU, and rejects an offer by Dark ProtoMan to join Nebula.
