Flag - Season 1 Episode 10 SDAC + 1

Investigators from UN HQ are sent to SDC, blocking their activity. In the background of a picture of the temple's leader, the flag is spotted. Eversalt, backed by the complete SDC team, decides to ignore orders and launch a fact finding mission into the temple. Ichiyanagi is freed from investigative detention so he can pilot a smaller mecha model he was involved in developing. One member of the investigators, only named Chief, backs the operation by delaying information sent to HQ. Shirasu is instructed by Eversalt to document the operation, for a possible future court martial trial. SDC intrudes the temple and finds the flag, but fails to capture it. Meanwhile, the temple's masked soldiers supported by improvised tanks and a mecha of unknown origin capture UNF's headquarters in a surprise attack and hold staff hostage.
