Rows of incubation tubes illuminated the G-Corporation facility. Researchers come and go, taking turns researching Kazuya's Devil Gene and seeking to recover his dead body. However, as the days, weeks, months, and years pass, Kazuya's form deteriorates with each experimental attempt, and researchers lose patience. Until one day, when one tube broke into shards of reinforced glass, there was no sign of Kazuya's body, forcing a hapless researcher to walk into the dimly illuminated incubation chamber to secure the space before other members could safely collect additional experiments.
