(No system + non-immortality + daily + funny + combat + group portrait) In 2190, Blue Star, the United States conducted private human experiments. Unexpectedly, bacteria mutated in the human body and turned people into cannibals. At that time, humans were unable to kill ghosts, which made the ghost camp become more and more powerful, and the United States became a gathering place for ghosts. Some ghosts have awakened powerful powers and are called ghost kings. After the joint efforts of mankind, a few people among mankind awakened to become Onizuka swordsmen, and a fight between ghosts and humans was staged on Blue Star.
