Cold Demon

Twenty years ago, a witch from an extremely cold place came to this land carrying an ancient virus called "God Brain Cancer". Her appearance brought death, fear, despair... Later, a man who claimed to be God appeared, made a huge coffin from the bones of ferocious beasts from ancient times, and sealed the witch inside. Order began to be reestablished, and people woke up from their nightmares. They buried the coffin in a dead city, and regarded the man who surrendered the witch as a hero for everyone to admire. However, twenty years later, a young man with a brain cancer virus walked out of a small mountain village!
