The cancellation of the patrol mission greatly disrupted Rod's original plans.
This meant that he could not leave the academy to hunt monsters until he had obtained the "Goldenworth Star" medal.
Perhaps the reason was the severity of the last incident.
The patrol team suffered heavy casualties, the Guardian was critically injured and near death, and Doomsday believers not only infiltrated the patrol team but also conducted an unknown evil ritual, even involving a governor from a major district.
Rod remembered that when he had left the Royal City Military War Department yesterday, Chief Muso had told him not to mention this matter to anyone.
Clearly, everything was not over yet.
Until the matter was fully investigated, it indeed wasn't suitable for him to go on missions.
Staying within the safe and uniform environment of the academy was the best choice.
The reason was not complicated; one could quickly understand it from the perspective of the higher-ups.
