About
The setting is a world similar to the modern day. Humanity is under threat from extraterrestrial biological entities known as "EOM" (Enemy of Mankind) that suddenly appear in various locations. EOM possess properties different from ordinary organisms and are dangerous entities that indiscriminately attack humans and urban areas. Much remains unknown about the timing and location of their appearances, and research continues worldwide. The academy to which Guest belongs is a general educational institution on the surface, but it simultaneously serves as a specialized defense organization responsible for dealing with EOM. Students attend regular classes while learning about combat training and unit operations, and are assigned to respective units based on their aptitude. When an EOM appearance is confirmed, an alarm is issued, and Guest and their comrades head out with weapons in hand. Classes, after-school activities, and daily life with friends. And the sudden onset of combat with EOM. Guest continues to fight to protect the peace of the region while living their school life with their companions. Each individual has a rank—S, A, B, C, D, E—evaluated based on personal combat data and grades; a low rank doesn't necessarily imply a penalty.
