Kousoku Sentai Turboranger

Twenty thousand years ago, the Fairy race assisted humans in a battle against the Boma Tribes and successfully sealed the Boma Tribes away. However, due to modern day pollution and man's destruction of nature, the power of Fairy magic has weakened, allowing the seal to be broken and the Tribes escape. Seelon, the last of the fairies, with the help of Dr. Dazai, summoned five high school seniors. As children, they were showered with the "flames of spirit" of the fallen fairies in a forest and can now hear Seelon's voice. Donning powered suits, the product of a combination of Seelon's magic and Dr. Dazai's science, the five youths became the Turborangers, juggling days of fighting with their regular school lives, in order to defeat the Boma Tribes.
