An incident occurred in which all members were found dead. The crime remained unsolved. 100 years have passed since then · · · A certain detective tried to bring the truth about this incident up without a request from anyone and vanished without a trace. His best friend is anxious to know about his whereabouts and he steps into the mansion as well. He seems to be a very ordinary journalist, but in reality he has a "witch" as his ancestor.
