"We only need one minute! Ichibu Sentai Hayaiger!" (One Minute Sentai Fast-ger)

I don't have many details of the plot worked out yet, but both the Hayaigers and their enemies the Majikan (a portmanteau of majin meaning "demon" and jikan meaning "time") have the power to move at super speed for short bursts, so most of their battles only take one minute in-universe and would be shown with the rangers and monsters moving at normal speed while everything around them is in slow motion, kinda like the Clock Up gimmick in Kabuto. And the idea of one minute being all it takes to change everything could be a key theme in the story too, with the rangers and villains both trying to change the world/history/people's lives by changing one key moment. There could also be morals about making the most of the time you have and treasuring the little things instead of being consumed by regret. Maybe the Majikan come from an alternate timeline and are sustained by people's regret somehow?
