Valvrave the Liberator Season 1 anime
Humans have expanded into space in the 71st Year of the True Era and are now living in independent galactic colonies. The world is divided between two major countries: the Atlantic Rim United States and the Dorssia Military Pact Federation. These superpowers wage war on each other both on Earth and in outer space. A third faction, made up of Japan and Islands Of the Oceanian Republics (JIOR), has emerged in this war-torn age. They live peacefully, prosper economically, and maintain neutrality with their militant neighbours.
Kakumeiki Valvrave begins in an outer space JIOR Colony. Haruto Tokishima, 17, is shocked when a Dorssian fleet suddenly breaches the neutral colony. They want to seize the Valvraves, powerful but rumored mechanized weaponry hidden deep within Haruto’s Sakimori Academy school. Haruto discovers one of the Valvraves in the chaos. Haruto, whose friends are in danger, enters the mecha to sign a contract for its power and his humanity. Haruto and the Valvrave launch a revolution to liberate all of the planet with the help L-elf, an enigmatic Dorssian agent who is also a gifted strategist.
