Vol4 Ch3: Announcement

"S-rank phenomenon detected, highest priority precautionary alarms triggered, relaying to the E5 council, request permission to activate S-2-5" the director of Site S2 immediately picked up his communicator and frantically contacted every appropriate department.

Each S-rank containment sites usually only contained at most 5 anomalies at once, so compared to other containment sites, there wasn't much work to be done at these sites; but whenever there was actual work, it could only be a huge event.

S-2-3: Phenomenon Precaution Device had a total of five levels of alarm, ranging from D-rank to S-rank. Under normal circumstances, a D-rank anomaly being involved in a containment breach wasn't only common, but also insignificant, so there was no need to sound any alarms for them. Due to this, Site S2 was only responsible for sending out personnel to counteract containment breaches of C-rank or above.
