A monster that eats people, takes away their appearance and memory, and replaces them, " Werewolf". Wolves are integrated into human society, and they prolong their lives by eating people so that they cannot be understood by their surroundings. Someone who was close to me yesterday may be a fake today. When the fate of such a monster and the young man who "gostain" of "life" intersects, a strange story begins.
