Chihe Akutagawa was harmed by a villain in his previous life and was forced to become a ghost, but he did not want to become a ghost and ran to commit suicide in the sun. Ghost Dance Tsuji Muzan sighed, this person has a noble character and cannot be contaminated by mortals. So he bowed three times and left; but unexpectedly, Chihe Akutagawa was not dead, and his soul still existed. He signed a contract with the system and was reborn as Chihe Akutagawa, befriended Akimichi Nahiro, and killed ghosts together. He vowed to get rid of all ghosts in the world and take revenge on businessmen who had interests in dealing with ghosts.
