The system connects reality and the underworld, and is a transfer station between the two worlds... Some people have the opportunity to get passes - people who died due to accidents, people who were locked out of the gate of hell because of too much resentment, people who have not yet waited for reincarnation and received recruitment flyers. These people will enter the ABD area after completing the initial copy. In addition, there are some special groups who live in the world and accidentally break through the entry and exit. They will be assigned by the system to enter Area C to open their own copy world.
Concept: enrich the inner drama of the cutie and the system's anthropomorphic body to overcome the levels, and gain friends and a growing story
