Gunslinger Stratos: The Animation

In the year 2115, the island nation once known as Japan is now called the "17th Far East Imperial City Management District." The people were promised a peaceful life, though it came at the cost of some comforts they once knew. Most believed their days would remain unchanging, with tomorrow no different from today. None realized their society was on the brink of collapse. A rare disease known as "Degradation" was spreading across the world, slowly reducing its victims to piles of sand as their bodies disintegrated. Tohru Kazasumi, an ordinary student, finds himself caught in a conflict between his world and the parallel dimension of "Frontier S (Stratos)." Forced into battle, he must face his own counterpart from this alternate reality. As their destinies intertwine, the futures of both worlds hang in the balance. Will they ever find peace?
