Seihou Tenshi Angel Links

Within the stars lie space pirates ready to take out unsuspecting vessels. Working to defend the transporters who can’t afford escorts is a company known as Angel Links. Led by the 16-year-old Meifon Li, they work to keep the stars safe for those just trying to do their jobs—and free of charge! But Meifon’s past is about to catch up with her and give them a hell of a time.
