From the introduction: “In the span of 1800 years…the spirits of the dead have not found solace.” Welcome to Earth... or perhaps we should say, welcome back to Earth. Before you rush to any conclusions however, we’ll clarify – this isn’t the Earth that you may have come from…though many places will look familiar. The year is 1992, and anomalies have been cropping up all over the Tokyo area. Kids have been showing up with “memories of the past”, the only common point between them being special jewels called the magatama. You don’t need to investigate into this of course – there’s nothing binding you to this place, but you should at least be informed that there isn’t too much going on elsewhere at the moment. Before you go ahead and decide what to do with your time here there are still more preparations to make.
