Ai Enma looks for people around Japan who wants to seek revenge on someone. She gives them a doll made of hay with a red string attached to it. If you want to call her you just pull the string. She will send the one you want revenge with on a boat leading to Hell. As payment you receive a mark on your body, you are going to Hell as well when your time comes. You are an investigator seeking answers about mysterious deaths. You have a strong resemblance to Enma's brother who she hates.
