Hikonin Sentai Akibaranger/Fridge

In one of the promos, the trio is seen fighting at no one, which doesn't makes sense at that time. However, Hiroyo states in the end of Episode 1 that their fighting as the Akibarangers are all delusions. Cue Big "What?" by Nobuo.
The girly girl Moegi sounding like a guy when the ears come off may be a subtle jab at the high gender differences in yellow rangers. Especially when considering the Power Rangers.
Kabukicho coming back to life as the Monster of the Week for #5 makes a lot more sense when you realize that the Akibarangers were having a delusion that Yumeria's mom, who died five years ago, was visiting.
The three of them were chosen because their "talents" were complementary:
- Akagi is always thinking about scenarios in his head, in other words he has a narrative imagination;
- Yumeria draws manga, which means she has a visual imagination;
- Mitsuki is a martial artist, which gives her a physical imagination.
  Each of them contribute in their own way to making the delusion world work (for instance, Akagi could have imagined himself as a sentai hero, but he could not have thought up the costumes). In addition, it mirrors the roles of the three key people in a toku production: the writer, the designer and the director (with Hiroyo as the producer).
