[TOKU] The "kidnapped brides" episode in Sentai

So I'm sitting here watching Abaranger episode 28, and I've began to notice a trend: in nearly every Sentai series I've watched, there always seems to be an episode where the MOTW kidnaps brides on their wedding day to meet the needs of the villains.



Has anyone else caught onto this, and if so is there some sort of cultural significance to this, or is this just some on-going Sentai tradition?
