The Ninningers come across a new enemy, Dark Doctor Mavro, a remnant of the Shadow Line, who created his own, evil version of Aka Ninger serving under him by stealing the real Aka Ninger's Nintality, and because of it, Takaharu's life is now in danger. All hope seems lost until the Ninningers meet the ToQgers, who fought and defeated the Shadow Line in the past, and it's up to them to join forces in order to overcome this new crisis.
