Arknights: Touin Kiro S01

In the land of Terra, natural disasters with unknown causes are occurring irregularly in many regions. As a result, most people have migrated to developed cities to escape these disasters for years. "Oregium" has remained at the site of such catastrophes, causing rapid cultural progress due to its extremely high energy. However, it also brought an incurable disease called Oripathy. Since the bodies of those infected with Oripathy gradually crystallize and at the time of death become a new source of infection, in many countries, those afflicted with this disease are subjected to racial discrimination, forced labor, and persecution. Those who were oppressed by governments rise up in rebellion. "Rodes Isle", a pharmaceutical company that is researching a cure for Oripathy, gathers its army and begins to conquer to save all people from this disease.
