Hikonin Sentai Akibaranger vs. Ninja Captor is a crossover between two unofficial shows. It takes place after episode 14 of Akibaranger.
The Akibarangers have finally been recognized by Toei! However, they are only hired as local heroes, with the gimmick of them being "the first unofficial Sentai", well at least its something. They get positive feedback from fans, but some fans compare them to another unofficial Sentai, Ninja Captor. There can only be unofficial Sentai, and so the Akibarangers go to the delusion world where they square off with the seven ninjas to determine who stays, and who goes.
