Ibara no Ou

As the Medusa disease turns human bodies to stone, Kasumi enters suspended animation in the hope of waking when a cure exists. Instead, she opens her eyes inside a facility strangled by enormous thorns and crawling with lethal creatures.

With a handful of other survivors, she searches for a way out while trying to understand what happened during their sleep. Memories of the twin sister she left behind haunt every discovery. The deeper they move through the ruined complex, the harder it becomes to separate the catastrophe from the secrets surrounding Kasumi herself.
