Ep. 1: Lameness is Power

Pain is Power is the first episode of Hikonin Sentai Akibaranger. The first episode introduces the characters and concept of Akibaranger, but also (as stated) does not fully establish the story, leaving room for the next episodes to explain the concept of the Akibarangers.

Trivia

 * Hiroyo Hakase explains that for the Akibarangers to be an "official" sentai, they'd have to have an adaptation of their adventures on television, and merchandise. At the same time, however, she explains that the powers and enemies of the Akibarangers are delusions. Thus, the first episode never makes it clear whether the Akibarangers are "real world sentai" while all the others are fictional, or whether in order to join the ranks of official Super Sentai, they have to be recognized (like how Banban Akaza is featured in the next episode). The narration in the opening credits does however state that the series premise is not established in the first episode.
