Gunslinger Stratos: The Animation - S01

In A.D. 2115, the island nation once called Japan is now known as the "17th Far East Imperial City Management District." Its citizens were promised a peaceful life in exchange for some of the comforts they had been used to. People believed their lives would never change and that tomorrow would be the same as today. No one suspected the impending doom their society was about to face. "Degradation," a rare disease that caused the human body to completely break down into a mere pile of sand, was slowly but surely spreading throughout the world. Tohru Kazasumi, an ordinary student, becomes caught up in a battle spanning multiple universes between his world and the parallel world of "Frontier S (Stratos)." This means Tohru must fight himself from an alternate world. Their futures collide as their paths cross. Will both worlds ever find peace?
