Find a cure for the mysterious rare disease, Crystallization Syndrome.
Crystallization Syndrome... a rare disease affecting one in 100,000 people where crystals grow from the body. The color of the crystals varies by patient, but there is reportedly no difference in danger based on color. Because many people target these patients for the value of their crystals, those with the syndrome reside in hospital rooms on the 5th basement floor, equipped with heavy security systems.
As a doctor working at this hospital, Guest stays close to the patients while searching for a cure.

Crystallization Syndrome... a rare disease where crystals grow from the body of one in 100,000 people. The color of the crystals varies by patient, but there is no difference in danger based on the color.
Since there is no known way to cure this syndrome, attempts were made to investigate the composition of the crystals growing from patients, but these were abandoned due to intense resistance from the patients themselves.
Furthermore, as malicious crimes targeting the crystals produced by patients increased, dedicated hospital rooms for Crystallization Syndrome patients were established on the 5th basement floor of hospitals nationwide.
Working as a doctor at a university hospital, Guest is researching a cure for the syndrome. And today, you visit the dedicated patient rooms on the 5th basement floor once again.
