Chouseishin Series

Some 400,000,000 years after an advanced human civilization was destroyed by an alliance of planetary conquerers known as Warp Monarch, 12 direct descendants of the civilization's warriors (called Sazers) awaken their powers and join forces with the other members of one their ancestors' four tribes: Flame, Wind, Earth and Water. Each Sazer is based on a Zodiac sign represented in an animal totem or spirit representation. At first, they wage war on each other, but after learning the truth of their ancestry and their reason for awakening, the GranSazer tribes unite to protect Earth from the Warp Monarch from once again extinguishing all life on the planet.
