Arknights: Prelude to Dawn

Originium transforms the world of Terra by providing enormous energy and enabling Arts that resemble magic, but it also causes Oripathy, an incurable disease. The Infected are discriminated against and driven from society, and the Reunion movement that arose around their suffering has become a violent force threatening entire cities. During one catastrophe, Rhodes Island enters the conflict to rescue an amnesiac Doctor whose strategic ability is desperately needed.

Amiya and her companions fight to protect the Infected from persecution without accepting terrorism carried out in their name. As they confront Reunion's leaders, the line between victim and enemy becomes increasingly difficult to draw, revealing that the disease may not be Terra's greatest danger; the way people choose to treat those who carry it may be worse.
