In a gray area where the "consciousness uploading" technology has just been lifted by law, a private company called "Higanbashi" provides a secret service - emergency consciousness scanning and temporary digital preservation ("digital body") for people who are dying or have just died, with a validity period of only 7 days. After 7 days, the digital body must be guided to "voluntarily" dissipate, otherwise it will fall into unpredictable data collapse. This service is expensive and borderline ethical, and is only designed to meet the private needs of customers to say "final farewell" to their loved ones or to deal with unresolved wishes.
