Thirty years after the apocalypse, humanity has established survivor bases and largely returned to its pre-apocalyptic way of life. However, there has still been no progress on a vaccine against zombies. Then, exactly thirty years after the apocalypse, a little girl dressed in old-fashioned clothes suddenly appears in the most important part of the base, the research institute. She claims to be a disciple of Wanhua Shumo, has memories from before the apocalypse, and possesses a special skill: drawing aggro.
