Ghost Hunt ~ Repeated Past

Mai Taniyama works at Shibuya Psychic Research or short SPR. Up until now they solved every case and they all made it out alive, but will all of that change? What happens when they get a case involving Mai's past? Will they solve the case and live there lives... or will everything change in the blink of an eye?

I know that this is a well known fact, but I do NOT own ghost hunt!
