Female, the original host whose body Yan Shaonan now inhabits. She is 21 years old with F-rank physique and E-rank mental power. Her biological mother died in an accident when she was 23 weeks pregnant, and she survived only thanks to a high-grade federal incubation pod. She is the stepdaughter of Aurora Terisa. Mary always lived carefully like a temporary guest in her stepmother's household, never causing trouble. She was exiled to Planet 627 by Gibson's scheme and got sick in the poorly equipped base station, eventually dying, which is when Yan Shaonan transmigrated into her body.
