Welcome to Ninja World

Overview

When Ikki wins two free tickets to popular Ninja Park, Erika persuades him to take her as his free guest. Ikki's first choice was Karin, but Erika wants to do a story on the park. Ikki reluctantly agrees because Erika took one ticket and wouldn't give it back. The main attractions to the park are the Explosive Ninja Show that features Ninja-Type Medabot Nin-Ninja and Kunoichi (Female Ninja)-Type Medabot Icknite, as well as the Ninja Castle that says closed for renovations. Disappointed, Ikki and Erika proceed to the Ninja Show. As the Ninja Show begins, Ikki and Erika notice that the monsters in the show look very much like the Rubberobo Gang. Seaslug has decided to hold Ikki and Erika captive until renovations are completed on their new base Ninja Castle! The Rubberobo Gang has stolen the Medals of Nin-Ninja and Icknite, and has complete control over them. Intuitively knowing that Ikki and Erika are in trouble, Metabee and Sailor-Multi (nicknamed Brass) come to their rescue.
