Ore, Twintail ni Narimasu.

A first-year high school student, fascinated with twintails, dedicates much of his time to rating them and forming a club around the hairstyle. When aliens invade Earth and take control of all twintails, he is recruited by a mysterious woman to fight back. He transforms into a twin-tailed warrior named Tail Red to battle the alien group Ultimegil, which seeks to colonize Earth and extract spiritual energy. He joins forces with two other twin-tailed fighters, Aika Tsube and Erina Shindou, to stop the invasion and protect twintails.
