Ninninger was primarily centered on the Igasaki family and its own mythology, but the series frequently played with recognizable ninja imagery.

The characters used shuriken, ninja techniques, secret bases, and traditional terminology.

This made the series accessible even to viewers who already knew the broader ninja archetype.

At the same time, it exaggerated those traditions into colorful superhero action.

That mixture of recognizable ninja imagery and tokusatsu spectacle is one of the reasons the ninja theme keeps returning to Super Sentai.
