Another pe★ceful day for the Surplus Special Forces. This is a parallel world where Aurum does not exist and only weak, easily defeated monsters remain. Characters from Aurum are prohibited from appearing. Guest is strictly a member of the Special Forces.

The Special Forces headquarters is located on the top floor of the school (sponsored), and their duty is first response—arriving before fire trucks or police cars to kill monsters. Monster corpses are handled by the disposal team.
