In the ruthless world of animals, big strong animals dominate and feed on small weak animals. To buck this natural system, small animals founded a secret organization called <MINIFORCE>. Rigidly selected mutants, who have special powers, were trained to become top secret rangers. Fighting against vicious animals or human villains who harass innocent animals, and rescuing small animals in danger are not the ultimate goal of rangers, but it continues beyond: to find the way all living creatures on the Earth can live together peacefully. Simple but never easy to achieve. But, nothing is impossible to our four elite rangers. <MINIFORCE>'s top mission is to protect small animals from human villain “Nein” and his underling lizard “Pascal” in a village called “Blue Bell”. Animals in danger? No problem! When “Force-Gem” alerts, it's time to get suit on! With supernatural rangers and their transforming mechanics “Force-Weapon”, “Force-Car”, and “Force-Bot”, you'll get more and more drawn into sensational days of <MINIFORCE>!
