First Sentai series without any flying fortress and very reminiscent of Mighty Morphin Power Ranger first season.
20,000 years ago, the Faerie race fought against the Violent Demon Tribe and sealed them away. Now due to modern day pollution, the power of Faerie's magic has weakened, allowing the seal to be undone and the Tribes to go free.
With Dr. Dazai, Seelon, the last of the Faerie, summoned five high school seniors who were showered with the "flames of spirit" of the fallen Faeries in a forest as children, now allowing them to hear Seelon's summons.
Donning powered suits, the product of a collaboration between Seelon's magic and Dr. Dazai's science, the five became the Turborangers to fight the Tribes. They transform by saying "Turboranger."
