Arknights: Perish in Frost

In this world, contracting a disease slowly turns your body to crystal — and society's response is to treat you like garbage. That's the setup for Arknights: Perish in Frost, the second season of the Arknights anime. Rhodes Island, a pharmaceutical company slash paramilitary group led by the young Amiya, is trying to cure this disease called Oripathy while also dealing with Reunion — a violent rebel movement of infected people who are done being oppressed and have already burned one city to the ground. Now they're headed for Lungmen, and Chief Ch'en of the city's guard has to figure out how to protect a place that honestly kind of deserves what's coming. The Doctor, Rhodes Island's amnesiac strategist, is back too, piecing together tactics and fragments of a lost past. This 8-episode TV series from Yostar Pictures leans hard into moral gray areas — nobody's cleanly good or evil here, and the show doesn't pretend otherwise. The animation mixes 2D and 3D in a way that makes the combat sequences genuinely fluid, and Yuki Hayashi's soundtrack carries the weight of the darker moments well. The tone is heavy and political, closer to Fate/Grand Order: Babylonia's blend of lore and action than the lighter side of game adaptations. If you enjoyed Girls' Frontline or Azur Lane but wanted something with more narrative teeth, this one hits differently. Just make sure you've watched the first season — this picks up right where it left off.
