19XX, a scientist, Doctor Nagano discovers in his laboratory in Osaka the "Saisei" (再生). A molecule that can regenerate cells and thus give eternal life to whoever consumes it. Knowing the importance of his discovery, he made an announcement to the Japanese Academy of Sciences (ASJ) which saw in this molecule the dangerousness of such a discovery. Thanks to an alliance with the army, the ASJ created a secret organization (Saisei Secret) in order to eliminate all traces of the research of Doctor Nagano in agreement with the scientist. After many failures in trying to destroy the (Test) tablets of 再生, it was decided to seal them in a mausoleum. Taking advantage of a nuclear disaster, a team of scientists begins construction of the mausoleum on an abandoned island off the coast of Sendai in Japan. Recent research had found important properties of resistance to heat and radioactivity of alabaster, which makes it an ideal material for the realization of the structure. The construction of the building lasted only 3 days with the help of military equipment.
