Souji is an ordinary high school student, though, he has obsession of twintails. One day, a girl called Thouars approached him as monsters appearing one after another, claiming him to be only man with the most potential of using Tail Gear, and entrusted him one to fight the monster, by transforming into Tail Red.

Twintails: the glory of all mankind—or at least that is what first-year high school student Souji Mitsuka believes. At school, Souji spends most of his time daydreaming and rating girls' twintails, even going as far as creating a club dedicated to the hairstyle. His obsession does not go unnoticed, however; when monsters from outer space attack Earth and claim the world's twintails for themselves, a strange woman named Twoearle enlists Souji to fight back using twintails of his own!
 
By transforming into the twin-tailed warrior Tail Red, Souji combats the vicious alien organization known as Ultimegil, whose main goal is to colonize Earth and steal everyone's spiritual energy, or "attribute power." Alongside fellow twin-tailed fighters Aika Tsube and Erina Shindou, Souji must find a way to defeat the invading army and defend the twintails he holds so dear.

Souji Mitsuka is an ordinary high school boy who has an obsession for twintails. One day he encounters a mysterious girl named Twoearle, who is from a parallel world, when monsters appear in his town and declare that all twintails in the world belong to them. These monsters feed off "attribute strength," the spiritual energy of humans. Twoearle entrusted Souji with Tail Gear, imaginary armor initiated by powerful twintail attributes. With the armor, Souji transforms into a girl and twintail warrior branded Tail Red, to protect Earth.
