King of Thorn

いばらの王 -King of Thorn-

When the petrifying Medusa virus spreads across the world, the organization Venus Gate freezes 160 chosen carriers in cold sleep until a cure can be found. Kasumi enters cryostasis without her twin sister Shizuku, but wakes far earlier than promised inside a facility overrun by monstrous thorned vines and prowling creatures. With a handful of other survivors, she has to escape the ruined complex and piece together what happened during the years she was supposed to be asleep.
